This application is a continuation-in-part of U.S. application Ser. No. 18/780,213, filed on Jul. 22, 2024, which claims the benefit of U.S. Provisional Application No. 63/605,199, filed on Dec. 1, 2023, each of which is incorporated by reference herein in its entirety.

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present disclosure relates to non-rigid and rigid portable containers and methods of manufacturing and use therefore, including a container with an insulating lid, which is also referred to as a cooler.

2. Description of the Background of the Disclosure

Coolers can be useful to transport, physically protect, and thermally insulate various items in solid and liquid form. For example, beverage containers, including aluminum cans or glass bottles for beer, seltzers, non-alcoholic beverages and the like, are often stored within a rigid or non-rigid portable cooler in large quantities and transported to a particular location for consumption. Fluid beverages are also often enjoyed at cold temperatures and, thus, it is desired for coolers to thermally insulate the fluid beverages during transport and/or during storage on-site. Further, coolers with waterproof closures are desired to prevent liquid from entering the cooler and coming into contact with contents sored therein. In particular, it is desired that coolers include multiple layers of waterproof protection to ensure that liquid does not enter the cooler while the cooler is closed.

Additionally, it is contemplated that any manufacturing methodology may be utilized, without departing from the scope of the disclosure. For example, one or more of welding, e.g., high frequency, ultrasonic welding, or laser welding of fabric, or metal/alloy welding, gluing, stitching, molding, injection molding, blow molding, stamping, deep-drawing, casting, die-casting, rotational molding, or additive manufacturing processes may be used, as well as various finishing processes, including drilling, deburring, grinding, polishing, sanding, or etching processes, among many others, may be utilized to construct the various container structures, or portions thereof, described throughout the disclosure.
FIGS. 1-6 illustrate various aspects of an implementation of a container 100, which may be configured as an insulating container, a cooler, or an insulative enclosure, according to aspects of the present disclosure. In some applications, the container 100 is configured for transport, protection, and thermal insulation of one or more beverage containers, food items, and/or a free fluid (not shown). It should be understood, however, that the teachings herein are not limited to any particular beverage container, and are applicable to enclosures for containers of other products, including solids and liquids of various forms, temperatures, and compositions according to aspects of the present disclosure. In some examples, the container 100 comprises an outer portion or shell 102 and an inner portion or liner 104 (see FIG. 7 ) that is configured to fit within a cavity 108 (see FIG. 6 ) defined by the shell 102. The shell 102 includes a base 110 defining a front wall 112, a rear wall 114, a left wall 116, and a right wall 118, each of which extend upwardly from a bottom wall 120 to form a perimeter of the base 110.
In some aspects, each of the front, rear, left, right and bottom walls 112, 114, 116, 118, 120 of the base 110 are substantially planar walls that meet one another at curved corners of the base 110. The base 110 of the container is configured as a base assembly that includes an outer base layer 122 defined by the shell 102, an inner base layer 124 defined by the liner 104 (see FIG. 7 ), and a base insulation layer 126, which are best shown and described in relation to FIG. 9 . Referring again to FIGS. 1-6 , the base 110 has a top or first end 128 and a bottom or second end 130 that is opposite the first end 128. In some aspects, the container 100 defines a y-axis 132 that extends between the first end 128 and the second end 130, i.e., in a direction that is parallel to the outer base layer 122, a z-axis 134 that extends between the front wall 112 and the rear wall 114 in a direction that is perpendicular to the y-axis 132, and an x-axis 136 that extends between the left wall 116 and the right wall 118 in a direction that is perpendicular to the y-axis 132 and the z-axis 134. It is contemplated that the y-axis 132, the z-axis 134, and the x-axis 136 define corresponding planes of the container 100. For example, a YZ plane (not shown) extends along the y-axis 132 and the z-axis 134, a YX plane (not shown) extends along the y-axis 132 and the x-axis 136, and a ZX plane (not shown) extends along the z-axis 134 and the x-axis 136.
Referring specifically to FIG. 1 , there is a first closure 138 at the first end 128 of the base 110 that extends along the periphery of the top of the front, left, and right walls 112, 116, 118 of the base 110, and at least partially along the periphery of the top of the rear wall 114 of the base 110. In particular, the first closure 138 is integral with the structure of the base 110 and serves as a connection point between the base 110 and a moveable lid 140. For example, the first closure 138 may be a zipper, rail-type closures, hook and loop fasteners, tabs, interference fitting closures, interlocking closures, magnetic closures, and/or any other suitable type of fastener, without departing from the scope of the present disclosure. In some examples, the first closure 138 is a waterproof closure that is configured to prevent liquid from entering the cavity 108 (see FIG. 7 ) when the lid 140 is arranged in a closed position and the first closure 138 is sealed. For example, the first closure 138 may be watertight up to about 5 pounds per square inch (psi) of atmospheric pressure, or up to about 9 psi of atmospheric pressure, or up to about 15 psi of atmospheric pressure, or at atmospheric pressures greater than about 1 psi.
In some aspects, the lid 140 is configured as a lid assembly and includes a front wall 142 a rear wall 144, a left wall 146, and a right wall 148, each of which extend downwardly from a top wall 150. In some aspects, each of the front, rear, left, right and top walls 142, 144, 146, 148, 150 of the lid 140 are substantially planar walls that meet one another at curved corners. The lid 140 is movably coupled to the base 110, such that when the lid 140 is in a closed position, i.e., when the lid 140 is secured to the base 110 via the first closure 138, each of the walls 112, 114, 116, 118 of the base 110 are flush with the corresponding walls 142, 144, 146, 148 of the lid 140, respectively. Put another way, when the lid 140 is in a closed position as illustrated in FIGS. 1-6 , the front wall 112 of the base 110 and the front wall 142 of the lid 140 at least partially define a shared plane, the rear wall 114 of the base 110 and the rear wall 144 of the lid 140 at least partially define a shared plane, the left wall 116 of the base 110 and the left wall 146 of the lid 140 at least partially define a shared plane, and the right wall 118 of the base 110 and the right wall 148 of the lid 140 at least partially define a shared plane. In some embodiments, the walls 142, 144, 146, 148 of the lid 140 are not flush with the corresponding walls 112, 114, 116, 118 of the base 110. For example, the lid 140 can define a larger perimeter than the base, and/or the lid 140 can define a tapered profile in a vertical direction, e.g., along the y-axis 132. In some examples, the container 100 further includes a front pocket 152, straps 154, side handles 156, and/or attachment rings 158, as will be discussed in greater detail below.
Referring specifically to FIGS. 2 and 3 , front and side elevational views, respectively, are illustrated of the container 100. It is contemplated that aspects relating to the right wall 118 of the base 110 as described herein are also applicable to the left wall 116 of the base 110. Various dimensions of the container 100 are shown, including an external height 160 of the container 100, an external depth 162 of the container 100, and an external width 164 of the container 100. Each of the external height, depth, and width 160, 162, 164 of the container 100 are measured along the y-axis 132, the z-axis 134, and the x-axis 136 respectively. As such, it will be appreciated that a height may be measured in a direction that is parallel with respect to the y-axis 132, a depth may be measured in a direction that is parallel with respect to the z-axis 134, and a width may be measured in a direction that is parallel with respect to the x-axis 136. In the illustrated embodiment, the external height 160 is illustrated as a maximum height of the container 100 in a closed position, the external depth 162 is illustrated as a maximum depth of the container 100 in a closed position, and the external width 164 is illustrated as a maximum width of the container 100 in a closed position.
In some aspects, the external height 160 of the container 100 may be between about 50% and about 150% of the external width 164, or between about 50% and about 100% of the external width 164, or between about 75% and about 100% of the external width 164, or between about 80% and about 90% of the external width 164, or about 85% of the external width 164 of the container 100. In some aspects, the external depth 162 of the container 100 may be between about 50% and about 150% of the external height 160, or between about 50% and about 100% of the external height 160, or between about 75% and about 100% of the external height 160, or between about 75% and about 85% of the external height 160, or, about 80% of the external height 160 of the container 100.
Still referring to FIGS. 2 and 3 , the container 100 further includes a pocket 152, e.g., a front pocket, on the front wall 112 of the base 110. It is contemplated that the pocket 152 may be formed in the shell 102 so as to be flush with front wall 112 of the base 110, or the pocket 152 can be formed as an external pocket on the front wall 112. In some aspects, the container 100 includes additional pockets (not shown) located on one or more of the walls 112, 114, 116, 118 of the base 110. In the illustrated non-limiting example illustrated in FIGS. 2 and 3 , the pocket 152 is a substantially rectangular, external pocket that protrudes outward from the front wall 112 of the base 110, e.g., in a direction along the z-axis 134 (see FIG. 1 ).
In some aspects, the pocket 152 is integrally formed with the front wall 112 of the base 110, or the pocket 152 is coupled to the front wall 112 of the base 110 via stitching, glue, welding, and/or another suitable fastening technique. The pocket 152 is configured to hold a variety of objects, such as, e.g., cell phones, wallets, small purses, car keys, a beverage container, a beverage enclosure that contains a beverage container, and/or other objects sized and shaped accordingly. In addition, the pocket 152 has a second closure 166 extending at least partially therealong, e.g., in a direction that is parallel to the z-axis 134, and the second closure 166 is substantially similar to the first closure 138. For example, the second closure 166 may be a zipper, waterproof closure, rail-type closures, hook and loop fasteners, tabs, interference fitting closures, interlocking closures, magnetic closures, and/or any other suitable type of fastener, without departing from the scope of the present disclosure.
Various dimensions of the pocket 152 are shown in FIGS. 2 and 3 , including a height 168 of the pocket 152 measured along the y-axis 132, a depth 170 of the pocket 152 measured along the z-axis 134, and a width 172 of the pocket 152 measured along the x-axis 136. In some aspects, the height 168 of the pocket 152 may be between about 25% and about 75% of the external height 160, or between about 50% and about 70% of the external height 160, or between about 50% and about 60% of the external height 160, or about 57% of the external height 160 of the container 100. In some aspects, the depth 170 of the pocket 152 may be between about 5% and about 50% of the external depth 162, or between about 5% and about 25% of the external depth 162, or between about 5% and about 15% of the external depth 162, or about 10% of the external depth 162 of the container 100. In some aspects, the width 172 of the pocket 152 may be between about 50% and about 100% of the external width 164, or between about 60% and about 80% of the external width 164, or between about 70% and about 80% of the external width 164, or about 77% of the external width 164 of the container 100.
Referring specifically to FIG. 2 , and as discussed above, the container 100 further includes straps 154, e.g., straps for carrying the container 100. For example, the container 100 includes a front or first strap 154A coupled to the front wall 112 of the container 100 and a rear or second strap 154B coupled to the rear wall 114 (see FIG. 4 ) of the container 100. It is contemplated that the straps 154 may be formed of webbing, such as, e.g., nylon webbing, or other materials that may include, among other, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, or rope. In some aspects, each strap 154 has a thickness of between about 0.50 millimeters and about 2.0 millimeters, or between about 1.0 millimeters and about 1.5 millimeters, or about 1.3 mm. While FIGS. 1-6 illustrate the container 100 as including both the first strap 154A and the second strap 154B, it is contemplated that fewer or additional straps may be coupled to the containers 100. In some aspects, the straps 154 are configured to support less than about 100 pounds (45.4 kilograms), or less than about 150 pounds (68.0 kilograms), or less than about 200 pounds (90.7 kilograms), or less than about 250 pounds (113.4 kilograms).
Referring again to the non-limiting example illustrated in FIG. 2 , the straps 154 are similarly sized and configured to be coupled at midpoints thereof by a handle flap 174. In some aspects, the handle flap 174 is carried by the front strap 154A or the rear strap 154B, and the handle flap 174 further comprises a fastener for coupling opposing ends of the handle flap 174 to each other. For example, the handle flap 174 is carried by the second strap 154B and is configured to have a pair of fasteners (not shown) comprising male portions (not shown) located on a first end of a first surface and female portions (not shown) located on a second end of the first surface, with the first end being opposite the second end. As such, when the midpoints of the first strap 154A and the second strap 154B are proximate each other (see FIG. 3 ), the second end of the handle flap 174 may be wrapped around a portion of the first strap 154A so that the male and female portions of the pair of fasteners (not shown) are coupled together, thereby securing the first and second straps 154A, 154B together.
In some examples, the straps 154 are coupled to the base 110, e.g., the front wall 112 and the rear wall 114 (see FIG. 4 ), via patches (not shown) that are attached to or formed integrally with the shell 102. Put another way, the straps 154 are attached, e.g., adhered, stitched, welded, and/or otherwise fastened, to patches (not shown) which in turn are coupled to the base 110. In some aspects, the patches (not shown) are coupled to the exterior of the shell 102 such that the patches (not shown) are visible, or the patches (not shown) are covered by, i.e., disposed beneath, the shell 102. For example, the patches (not shown) are covered by flaps 176 formed in the shell 102 so as to cover the attachment points of the straps 154 to the base 110.
Referring now to FIG. 3 , the container 100 further includes side handles 156 and attachment rings 158, e.g., a component having an aperture extending therethrough, that are coupled to the sides, e.g., the left wall 116 (see FIG. 1 ) and the right wall 118 of the container 100. Specifically, the side handles 156 and the attachment rings 158 are located approximately centrally between the front wall 112 (see FIG. 1 ) and the rear wall 114 (see FIG. 4 ). Further, the side handles 156 and the attachment rings 158 are located closer to the lid 140 than the bottom wall 120 (see FIG. 6 ), although it will be understood that the side handles 156 and the attachment rings 158 can be coupled to the container 100 at any suitable position on the base 110.
In some aspects, the side handles 156 are coupled to the container 100 via patches (not shown) that are attached to or formed integrally with the shell 102. Put another way, the side handles 156 are attached, e.g., adhered, stitched, welded, and/or otherwise fastened, to patches (not shown) which in turn are coupled to the base 110. For example, both ends of one side handle 156 are attached to one or more patches (not shown) that are coupled to the base 110. In some aspects, the patches (not shown) are coupled to the exterior of the shell 102 such that the patches (not shown) are visible, or the patches (not shown) are covered by, i.e., disposed beneath, the shell 102. For example, the patches (not shown) may be covered by flaps 176 formed in the shell 102 so as to cover the attachment points of the straps 154 to the base 110. Further, it is contemplated that the side handles 156 may be formed of webbing, such as, e.g., nylon webbing, or other materials that may include, among other, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, or rope.
In some aspects, the attachment rings 158 are configured to receive opposing ends of a shoulder strap (not shown). In particular, each attachment ring 158 is configured to receive a clasp located at each opposing end of the shoulder strap (not shown) such that the clasp can be removably hooked to each attachment ring 158 to selectively attach and remove the shoulder strap (not shown) from the container 100 as desired. In some examples, the attachment rings 158 are coupled to loops 178 of fabric which in turn are coupled to the shell 102. For example, a single loop 178 extends through an aperture in a single attachment ring 158 so as to couple the attachment ring 158 to the right wall 118 of the base 110. Correspondingly, the loops 178 are coupled, e.g., stitched, adhered, welded, to patches (not shown) that are covered by the shell 102 and/or coupled to an interior (not shown) of the shell 102. In some examples, one side handle 156 and one loop 178 are connected to a single patch (not shown) on each side wall 116, 118 of the container 100, although it is contemplated that multiple side handles 156, loops 178, and/or attachment rings 158 can be coupled to the base 110 at a variety of different locations.
It is contemplated that the attachment rings 158 may be constructed from one or more polymers, metals, ceramics, glasses, alloys, or combinations thereof. In some examples, the attachment rings 158 may be constructed from polypropylene, neoprene, polyester, Dyneema, Kevalar, cotton fabric, leather, plastics, rubber, and/or rope. Further, the attachment rings 158 each define a substantially D-shape, e.g., D-rings, but the attachment rings 158 may include other shapes such as, for example, round, square, rectangular, triangular, or multiple rings with multiple attachment points and apertures. Moreover, it is contemplated that the loops 178 may be formed of webbing, such as, e.g., nylon webbing, or other materials that may include, among other, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, or rope.
Referring now to FIG. 4 , the rear wall 114 of the base 110 and the rear wall 144 of the lid 140 define a hinge 180 of the container 100. Specifically, the hinge 180 couples the base 110 to the lid 140 and defines a hinge axis 182 that extends between an interface of the base 110 and the lid 140 in a direction that is parallel with the x-axis 136. In this way, the lid 140 can be rotated about the hinge axis 182 when, e.g., the lid 140 is opened or closed. In some aspects, the hinge 180 is formed by the shell 102 and the inner liner 104 (see FIG. 7 ), meaning that the hinge 180 serves as a connection point between the shell 102 and the liner 104 (see FIG. 7 ). In some examples, the hinge 180 is a living hinge, and the hinge 180 allows the lid 140 to be actuated between an open position (see FIG. 7 ) and a closed position as illustrated in FIGS. 1-6 , and as will be discussed below in greater detail.
In some examples, the shell 102 is formed as an integral one-piece structure, or the shell 102 can be formed as a multiple component assembly. In the non-limiting example illustrated in FIG. 4 , the shell 102 is an integral one-piece component with a seam 184 that extends vertically, e.g., in a direction that is parallel with the y-axis 132, along the rear walls 114, 144, of the base 110 and the lid 140, respectively. In some aspects, the seam 184 is formed by joining sides of the one-piece shell 102 together using a suitable fastening technique, e.g., adhering, stitching, and/or welding, to secure the shell 102 around the container 100. Correspondingly, it is contemplated that the shell 102 may be constructed from neoprene, polyester, cotton fabric, mesh fabric, leather, plastics, rubber, nylon, and/or molded EVA (Ethylene Vinyl Acetate). In some examples, the shell 102 is made of or constructed from a synthetic fabric, e.g., polyester and/or nylon fabric. Further, the shell may include an outer and/or double-sided coating using, e.g., fabric, nylon, felt, thermoplastic polyurethane, etc. In some aspects, the container 100, e.g., the shell 102 and the liner 104, can withstand about 25 pounds (111.2 Newtons) or less of puncture force, or about 50 pounds (222.4 Newtons) or less of puncture force, or about 75 pounds (333.6 Newtons) or less of puncture force, or about 100 pounds (444.8 Newtons) or less of puncture force, or about 125 pounds (556.0 Newtons) or less of puncture force, e.g., puncture force provided during a benchtop puncture test.
Still referring to the non-limiting example illustrated in FIG. 4 , additional dimensions of the container 100 are shown, including a height 186 of the base 110 and a height 188 of the lid 140. Each of the base and lid heights 186, 188 are measured along the y-axis 132. In some aspects, the external height 160 is defined by the sum of the heights 186, 188 of the base 110 and the lid 140. In some aspects, the height 188 of the lid 140 may be between about 1% and about 25% of the height 186 of the base 110, or between about 5% and about 15% of the height 186 of the base 110, or between about 10% and about 15% of the height 186 of the base 110, or about 13% of the height 186 of the base 110.
Referring now to FIG. 5 , the top wall 150 of the lid 140 is substantially rectangular-shaped or square-shaped, although it is contemplated that the top wall 150 can be shaped differently than shown, e.g., circular, ovular, triangular, etc. In some examples, the lid 140 includes an upper or first strip 190 of material, an upper or first ridge 192, and a tab 194 that are each coupled to the top wall 150 of the lid 140. Specifically, the first strip 190 extends around the outer periphery of the lid 140 and is configured to protect and reinforce the lid 140. Put another way, the first strip 190 increases the rigidity of the lid 140. In some examples, the first strip 190 is configured as a corner support and/or joint, meaning that the first strip 190 wraps over the peripheral edge of the top wall 150 so as to couple the top wall 150 with each of the walls 142, 144, 146, 148 of the lid 140.
In other examples, the first strip 190 defines each of the walls 142, 144, 146, 148 of the lid 140, and the first strip 190 forms an upper or first joint 196A (see FIG. 9 ) between top wall 150 and the first closure 138 (see FIG. 1 ), as is best shown and described in relation to FIG. 9 . In some aspects, the first strip 190 is an integral one-piece structure, and the seam 184 formed along the rear wall 114 of the base 110 (see FIG. 4 ) extends into the first strip 190, meaning that sides of the first strip 190 are also joined together along the seam 184 (see FIG. 5 ) via, e.g., adhering, stitching, and/or welding. It is contemplated that similar fastening techniques may be used to couple the first strip 190 to the top wall 150. In some aspects, the first strip 190 is formed of a similar material as the shell 102, e.g., polyester fabric. In other examples, the first strip 190 is constructed of a more rigid material than the material of the shell 102.
Still referring to FIG. 5 , the first ridge 192 also extends around the top wall 150 of the lid 140. In particular, the first ridge 192 is inset from the peripheral edge of the top wall 150, i.e., inset from the first strip 190. In some aspects, the first ridge 192 defines a curved or semi-circular profile as best shown and described in relation to FIG. 10 , and the first ridge 192 extends upwardly, i.e., along the y-axis 132 (see FIG. 1 ), from the top wall 150. With continued reference to FIG. 5 , the first ridge 192 is formed integrally with the top wall 150 of the lid 140. For example, the first ridge 192 can be formed during manufacture of the lid 140 using, e.g., injection molding, blow molding, stamping, die-casting, etc. In some aspects, a logo 198 is also formed in the top wall 150 during the manufacture thereof. For example, the logo 198 can be compression molded, injection molded, printed, stamped, cast, pressed, and/or embossed in the top wall 150 of the lid 140.
In some examples, the tab 194 is coupled to the top wall 150 of the lid 140. Specifically, the tab 194 is inset from the front wall 142 of the lid 140 and extends outward and upward therefrom, e.g., in a direction towards the front wall 142 and away from the top wall 150 of the lid 140. In some aspects, the tab 194 is positioned on the top wall 150 inward relative to the first ridge 192, and the tab 194 partially extends over the first ridge 192. Further, one end of the tab 194 is coupled to the lid 140 via, e.g., adhering, stitching, and/or welding. In some aspects, the tab 194 is a rectangular tab, although it is contemplated that a variety of different shapes could be used for the tab, e.g., trapezoidal, ovular, triangular, etc. To that end, the tab 194 is sized so a user can easily grasp the tab to selectively open and close the lid 140, i.e., to actuate the lid 140 about the hinge axis 182. Using the tab 194 is particularly advantageous when the lid 140 or a portion thereof extends partially into the cavity 108 (see FIG. 7 ) when the lid 140 is in the closed position, as will be discussed below in greater detail. In some aspects, the tab 194 is constructed of neoprene, polyester, cotton fabric, mesh fabric, leather, plastics, rubber, nylon, metal, and/or molded EVA (Ethylene Vinyl Acetate). In one example, the tab 194 is constructed of a polyester sheet that is coupled at one end to the top wall 150 of the lid 140 and then folded over onto itself before being further fastened to the top wall 150.
Referring now to FIG. 6 , a bottom plan view is illustrated of the container 100. In some aspects, the bottom wall 120 of the base 110 is substantially rectangular-shaped or square-shaped, although it is contemplated that the bottom wall 120 can be shaped differently than shown. In some aspects, the base 110 includes a lower or second strip 200 of material and a lower or second ridge 202 that are coupled to the bottom wall 120 of the base 110. For example, the second strip 200 may mirror the first strip 190 (see FIG. 5 ), meaning that the second strip 200 extends around the outer periphery of the bottom wall 120 and is configured to protect and reinforce the base 110. In some aspects, the second strip 200 is configured as a corner support and/or forms a lower or second joint 196B (see FIG. 11 ) between the bottom wall 120 and the front, rear, left, and right walls 112, 114, 116, 118 of the base 110. Further, the second strip 200 is an integral one- piece structure. In some examples, the seam 184 formed along the rear wall 114 (see FIG. 4 ) of the base 110 extends into the second strip 200, meaning that sides of the second strip 200 are also joined together along the seam 184 (see FIG. 4 ) via, e.g., adhering, stitching, and/or welding. Correspondingly, the second strip 200 is coupled to the bottom wall 120 using a suitable fastening technique, e.g., adhering, stitching, and/or welding. In some aspects, the second strip 200 is formed of a similar material as the shell 102, e.g., polyester fabric, or a different material, e.g., rubber.
Still referring to FIG. 6 , the second ridge 202 may mirror the first ridge 192 (see FIG. 5 ), meaning that the second ridge 202 extends around the bottom wall 120 of the base 110 and defines a curved or semi-circular profile that extends downwardly, i.e., along the y-axis 132 (see FIG. 1 ), from the bottom wall 120. Correspondingly, the second ridge 202 elevates the container 100 above the ground or another surface when the container 100 is placed upright. This in turn prevents the bottom wall 120 from directly contacting the ground, which can reduce wear on the bottom wall 120. In some examples, the second ridge 202 is inset from the peripheral edge of the bottom wall 120, i.e., inset from the second strip 200. Moreover, the second ridge 202 is formed integrally with the bottom wall 120 of the base 110. For example, the second ridge 202 can be formed during manufacture of the base 110 using, e.g., injection molding, blow molding, stamping, die-casting, etc. In some aspects, a logo 204 is also be formed in the bottom wall 120 during the manufacture thereof. For example, the logo 204 can be molded or directly embossed into the bottom wall 120 of the base 110.
Referring now to FIG. 7 , the container 100 is illustrated in an open position or configuration in which the lid 140 has been rotated via the hinge 180. Thus, it will be understood that the lid 140 is capable of being rotated about the hinge axis 182 to uncover the cavity 108. In some aspects, the lid 140 can rotate at least 270 degrees via the hinge 180, or at least 180 degrees via the hinge 180. As discussed above, the hinge 180 serves as a connection point between the shell 102 and the liner 104. In particular, the shell 102 forms one side of the hinge 180, e.g., the side of the hinge along the rear wall 114 of the base 110, and the liner 104 forms an opposite side of the hinge 180, which is visible in FIG. 7 . Moreover, the liner 104 defines an innermost surface of the container 100 and an interior volume 206.
Specifically, the portion of the liner 104 in the base 110 is a cuboid or box-shaped container that is provided to nest within the cavity 108 of the shell 102 of the container 100 for storage, protection, and thermal insulation of contents, e.g., beverage containers, received in the interior volume 206. However, it is contemplated that the liner 104 can be formed in any suitable shape or combination of shapes, e.g., a cylinder. In some aspects, the liner 104 is a rigid container that is self-supporting and imparts structural integrity and form to the shell 102. In other examples, the liner 104 is provided as a soft and/or malleable material. In the non-limiting example illustrated in FIG. 7 , a snug or tight fit is provided between the shell 102, the liner 104, and/or an insulation layer, which may be an airtight or waterproof/resistant fit. For example, a sealant or compound may be applied between the liner 104 and the shell 102 to prevent ingress or egress of air, water, gases, fluids, and the like.
In some embodiments, the liner 104 is coupled to the shell 102 by, for example, fasteners, an interference fit, glue, stitching, or welding (ultrasonic welding, RF welding, laser welding), among others. In some embodiments, the liner 104 is removably, permanently, or semi-permanently coupled to the shell 102. For example, the liner 104 can be removably coupled to the shell 102 by fasteners that can be unfastened. In some embodiments, an adhesive may be applied to the liner 104 and the shell 102 for permanent or semi-permanent attachment. In some examples, the liner 104 is coupled to the shell 102, such as, e.g., by stitching provided on the walls 112, 114, 116, 118 of the base 110 near the first end 128 thereof. In the non-limiting example illustrated in FIG. 7 , the shell 102 is coupled to the liner 104 via welding, e.g., high frequency welding, ultrasonic welding, and/or laser welding, along the first closure 138 and the hinge 180. In some examples, the liner 104 and the shell 102 are configured to float when immersed in a body of water, thereby allowing the container 100 to buoyantly travel with or remain near a user engaged in a water activity and also preventing the container 100 from sinking. To accomplish such buoyancy, buoyant gases or materials may be provided between the liner 104 and the shell 102, or within the liner 104 and/or the shell 102, or coupled to the liner 104 and/or the shell 102.
Moreover, the liner 104 is constructed to be generally smooth, e.g., free of sharp corners or edges, although it is contemplated that the liner 104 includes one or more seams in some examples. Moreover, the liner 104 is configured to be coupled tightly to the shell 102 and to avoid tearing or ripping of the shell 102. In some examples, the liner 104 includes rigid portions or supports thereon, or a material that is substantially more rigid than the material of the shell 102, or a material that is substantially thicker than the material of the shell 102. Further, it is contemplated that a pull tab (not shown) may be coupled to the liner 104 to facilitate removal of the liner 104 from the shell 102. The liner 104 may be constructed from injection molded plastic, such as, e.g., polypropylene (“PP”), homopolymer PP, Copolymer PP, Random Copolymer, thermoplastics, and/or any other plastics or polyolefins, or combinations thereof.
With continued reference to FIG. 7 , the base 110 of the container 100 includes an outer base layer 122 defined by the shell 102, an inner base layer 124 defined by the liner 104, and a base insulation layer 126 disposed therebetween (see FIG. 9 ). In some aspects, the outer base layer 122, inner base layer 124, and base insulation layer 126 (see FIG. 9 ) define planar walls and are open on one end, e.g., the top or first end 128. When the container 100 is assembled, the inner base layer 124, i.e., the liner 104, is received and secured within the base insulation layer 126, i.e., the shell 102, and the base insulation layer 126 (see FIG. 9 ) is received and secured therebetween. As discussed above, the shell 102 and the liner 104 are coupled to one another at the hinge 180, and it is contemplated that the shell 102 and the liner 104 may not be directly coupled to one another at any other location on the container 100 other than the hinge 180.
However, in the non-limiting example illustrated in FIG. 7 , the outer base layer 122 and the inner base layer 124 are also coupled to one another along a portion of the first closure 138 that is coupled to the first end 128 of the base 110, i.e., a lower or first half 208A of the first closure 138. Put another way, a first half 208A of the first closure 138 extends around a periphery of the base 110 at the first end 128 thereof. In particular, the outer base layer 122 is coupled to an outer or first side 210A of the first half 208A of the first closure 138, and the base inner layer is coupled to an inner or second side 210B of the first half 208A of the first closure 138. In this way, a first joint 196A is formed between the shell 102 and the liner 104, which in turn secures the liner 104 to the container 100.
In some examples, the inner base layer 124 defines a seat 212 at the first end 128 of the container 100, and the seat 212 extends around an inner periphery of each of the front, rear, left, and right walls 112, 114, 116, 118 of the base 110 at the first end 128. In some aspects, the seat 212 defines a planar surface that is substantially parallel to the ZX plane (not shown), i.e., parallel to the z-axis 134 and the x-axis 136. Specifically, the seat 212 is formed atop the base insulation layer 126 (see FIG. 9 ) and below the first half 208A of the first closure 138. Thus, it will be understood that the first half 208A of the first closure 138 extends upward from the seat 212 in a direction that is parallel to the y-axis 132. In some aspects, the inner base layer 124 includes seat seams 214 along the peripheral edges of the seat 212, although it is contemplated that the inner base layer 124 may alternatively be constructed as a generally smooth, one-piece structure as discussed above. In some examples, the inner base layer 124 is secured to the other components of the base 110, e.g., the outer base layer 122, the base insulation layer 126 (see FIG. 9 ), and/or the first half 208A of the first closure, along one or more of the seat seams 214. Moreover, the seat 212 is configured to receive a corresponding structure of the lid 140 thereon when the lid 140 is in the closed position, as will be discussed below in greater detail.
Referring now to the non-limiting examples illustrated in FIGS. 7-8 , the lid 140 is configured as a lid assembly that includes an outer lid layer 222 defined by the shell 102, e.g., the top wall 150 of the lid 140 and the first strip 190, an inner lid layer 224 defined by the liner 104, and one or more lid insulation layers 226 (see FIG. 9 ) disposed therebetween. In some aspects, the inner lid layer 224 is an integral one-piece component, or the inner lid layer 224 includes a plurality of liner elements that are coupled to one another via, e.g., adhering, stitching, and/or welding. Moreover, a snug or tight fit is provided between the outer lid layer 222, the inner lid layer 224, and/or and the lid insulation layer(s) 226 (see FIG. 9 ), which may be an airtight or waterproof/resistant fit. For example, a sealant or compound may be applied between the liner 104 and the shell 102 to prevent ingress or egress of air, water, gases, fluids, and the like. In addition, the outer lid layer 222 and the inner lid layer 224 are coupled to one another along the hinge 180 (see FIG. 3 ) and a portion of the first closure 138 that is coupled to the lid, i.e., an upper or second half 208B of the first closure 138. In particular, the outer lid layer 222 is coupled to an outer or first side 228A of the second half 208B of the first closure 138, and the inner lid layer 224 is coupled to an inner or second side 228B of the second half 208B of the first closure 138. In this way, a second joint 196B is formed between the shell 102 and the liner 104, which in turn secures the liner 104 to the container 100. In some aspects, the second half 208B of the first closure 138 extends around a periphery of the lid 140.
In some aspects, the inner lid layer 224 and the lid insulation layer(s) 226 (see FIG. 9 ) are coupled to an underside 232 of the lid 140 and define a first portion or cover 234 and a second portion or plug 236. The cover 234 is coupled to the underside 232 of the lid 140 and protrudes therefrom opposite the top wall 150, e.g., along the y-axis 132 toward the base 110 when the lid 140 is in the closed position (see FIG. 9 ). Relatedly the plug 236 protrudes from the cover 234 opposite the top wall 150, e.g., along the y-axis 132 toward the base 110 when the lid 140 is in the closed position (see FIG. 9 ). In some examples, the cover 234 and the plug 236 define substantially rectangular profiles that are similar to the profiles of the base 110 and the lid 140. Moreover, the cover 234 and the plug 236 are aligned with one another, e.g., concentric with one another and the top wall 150 of the lid 140, along the y-axis 132 when the lid 140 is in the closed position (see FIG. 9 ). Still further, the cover 234 has a smaller area than that of the top wall 150 (see FIG. 5 ) of the lid 140, and the plug 236 has a smaller area than the area of the cover 234.
Put another way, such that the lid insulation layers 226 define a stepped profile that corresponds to the shape of the inner base layer 124 and the seat 212. For example, the cover 234 defines a first step surface or rim 238 around the plug 236, the rim 238 defining a planar surface that is substantially parallel to the ZX plane (not shown) when the lid is in the closed position (see FIG. 9 ). Relatedly, the plug 236 defines a second step surface or first/bottom plug surface 240 that abuts the interior volume 206 of the base 110 when the lid 140 is in the closed position (see FIG. 9 ). The bottom plug surface 240 is also a substantially planar surface that is parallel to the ZX plane (not shown) when the lid is in the closed position (not shown), meaning that the bottom plug surface 240 is parallel with respect to the rim 238. In addition, the plug 236 defines a second or side plug surface 242 around the periphery thereof, and the side plug surface 242 is configured to contact sides of the inner base layer 124 that define the interior volume 206 when the lid 140 is in the closed position (see FIG. 9 ), as will be discussed below in greater detail.
Referring now to FIG. 9 , a cross-sectional view is illustrated of the container 100 taken through line 9-9 in FIG. 2 , and the lid 140 is in the closed position. As discussed above, the base 110 of the container 100 includes the outer base layer 122 defined by the shell 102, the inner base layer 124 defined by the liner 104, and the base insulation layer 126 that is disposed between the outer base layer 122 and the inner base layer 124. In a similar way, the lid 140 of the container 100 includes the outer lid layer 222 defined by the shell 102, the inner lid layer 224 defined by the liner 104, a first lid insulation layer 226A disposed between the outer lid layer 222 and the inner lid layer 224, and a second lid insulation layer 226B covered by the inner lid layer 224. When the container 100 is assembled, the insulation layers 126, 226 are injected between the outer layers 122, 222 and the inner layers 124, 224, although it is contemplated that other configurations are also possible. In some aspects, the insulation layers 126, 226 are placed or slipped between the outer layers 122, 222 and inner layers 124, 224 during the manufacturing process. For example, the inner layers 124, 224 are received and secured within outer layers 122, 222, and the insulation layers 126, 226 are received or slipped between the outer layers 122, 222 and the inner layers 124, 224.
In some examples, the insulation layers 126, 226 may be secured, e.g., fastened, adhered, welded, to the outer layers 122, 222 and/or the inner layers 124, 224 at one or more points, or the insulation layers 126, 226 are floating insulation layers which are not coupled to the outer layers 122, 222 and/or the inner layers 124, 224. In the non-limiting example illustrated in FIG. 9 , the base insulation layer 126, the first lid insulation layer 226A, and the second lid insulation layer 226B are each shown as one-piece integral components, although it is contemplated that the insulation layers 126, 226 may alternatively be formed of multiple components. For example, the base insulation layer 126 may include side insulation pieces (not shown) that are secured to a bottom insulation piece (not shown) before the inner base layer 124 is overlaid thereon to form the interior volume 206. In some examples, the base insulation layer 126 is scored before being placed in between the outer and inner base layers 122, 124 to allow the base insulation layer 126 to be folded in the shape of the container 100. In addition, the insulation layers 126, 226 may be made of polyurethane, expanded polyurethane, open-cell or closed-cell foam, EVA foam, or any other known insulative material to enable the container 100 for ice retention over extended periods of time, such as, e.g., about 7 hours or more.
With continued reference to FIG. 9 , and as discussed above, the liner 104 defines an interior volume 206 in which fluid, beverage containers, or other objects are contained, when the liner 104 is positioned within the cavity 108 of the shell 102. In some aspects, the interior volume 206 defines an internal height 244, an internal depth 246, and an internal width (not shown). In some aspects, the internal height 244 is between about 50% and about 75% of the external height 160, or between about 60% and about 70% of the external height 160, or about 65% of the external height 160 of the base 110. In some aspects, the internal depth 246 is between about 50% and about 100% of the external depth 162, or between about 60% and about 80% of the external depth 162, or about 75% of the external depth 162 of the base 110. In addition, the interior volume 206 has a volume that is between about 1 gallon (3.79 liters) and about 20 gallons (75.71 liters), or between about 1 gallon (3.79 liters) and about 5 gallons (18.93 liters), or between about 5 gallons (18.93 liters) and about 10 gallons (37.85 liters), or about 5 gallons (18.93 liters).
In some aspects, the interior volume 206 is dimensioned so as to receive a particular quantity of beverage containers of a standard size in a vertical position and arranged in a grid-like fashion, i.e., m×n. For example, the interior volume 206 may be configured to receive twenty beverage containers arranged in a four-by-five grid, or twenty-four beverage containers arranged in a six-by-four grid, or thirty beverage containers arranged in a five-by-six grid, or thirty-two beverage containers arranged in an eight-by-four grid, or forty beverage containers arranged in an eight-by-six grid. However, different quantities of beverage containers may be received within the interior volume 206 and may be arranged differently, such as, e.g., stacked vertically atop one another and/or disposed in horizontal positions below the first closure 138 atop of each of the walls 112, 114, 116, 118 (see FIG. 1 ) of the base 110 such that the lid 140 can be rotated about the hinge axis 182 (see FIG. 7 ) to the closed position.
Still referring to FIG. 9 , the lid inner layer 224 and the lid insulation layers 226 define the cover 234 and the plug 236 of the lid 140. In particular, the cover 234 is defined by the inner lid layer 224 and the first lid insulation layer 226A, and the plug 236 is defined by the inner lid layer 224 and the second lid insulation layer 226B. In some aspects, the lid inner layer 224 also defines a partition layer 248 disposed between the first lid insulation layer 226A and the second lid insulation layer 226B, although it is also contemplated that the lid insulation layers 226 may alternatively be in direct contact with one another.
In some examples, the lid 140 is configured to seal the interior volume 206 from a surrounding environment when the lid is in the closed position. To that end, when the lid 140 is actuated about the hinge axis 182 (see FIG. 3 ) so as to be arranged in the closed position, the rim 238 defined by the cover 234 contacts the seat 212 formed by the inner base layer 124 atop the base insulation layer 126, and the plug 236 is inserted at least partially into the interior volume 206. Put another way, plug 236 extends past the seat 212 along the y-axis 132 to abut the interior volume 206 when the lid is arranged in the closed position. Further, as illustrated in FIG. 9 , the side plug surface 242 of the plug 236 contacts the sides of the inner base layer 124 that define the interior volume 206 when the lid 140 is in the closed position, thereby sealing the interior volume 206 from a surrounding environment.
In some examples, the plug 236 forms an interference fit with the liner 104, e.g., the sides of the inner base layer 124 that define the interior volume 206 when the lid 140 is in the closed position, which in turn seals the interior volume 206 from the environment. In this way, the cover 234 and the plug 236 of the lid 140 may create a generally water-and/or air-tight seal between the lid 140 and the base 110 when the lid 140 is in the closed position. That is, the interference fit defined by the liner 104 and the plug 236 helps prevent the container 100 from leaking any fluids from within and allows for a slower rate of heat transfer between the interior volume 206 and a surrounding or ambient environment of the container 100. In some examples, the lid 140 is configured to provide an air-tight and water-tight seal between the ambient environment and the interior volume 206, such that the container 100 is configured to be water-resistant and/or waterproof. In some examples, the seal may not be a completely air-tight or water-tight.
Correspondingly, it will be understood that in addition to the first closure 138, the shape(s) of the cover 234 and the plug 236 provide the seal between the ambient environment and the interior volume 206. In particular, and as illustrated in FIG. 9 , the cover 234 can define a height 250, a depth 252, and a width (not shown), and the plug 236 can also define a height 254, a depth 256, and a width (not shown). Each of the heights 250, 254, depths, 252, 256, and widths (not shown) are measured along the y-axis 132, the z-axis 134, and the x-axis 136, respectively. In some aspects, the height 250, the depth 252, and/or the width (not shown) of the cover 234 are greater than the height 254, the depth 256, and/or the width (not shown) of the plug 236, respectively. For example, the height 254 of the plug 236 may be between about 25% and about 75% of the height 250 of the cover 234, or between about 40% and about 50% of the height 250 of the cover 234, or about 45% of the height 250 of the cover 234. Further, the depth 256 of the plug 236 may be between about 50% and about 100% of the depth 252 of the cover 234, or between about 75% and about 90% of the depth 252 of the cover 234, or about 85% of the depth 252 of the cover 234.
In some examples, the depth 252 of the cover 234 is less than the external depth 162 of the container 100 and greater than the internal depth 246 of the interior volume 206. In this way, a gap 258 is formed between the cover 234 and the front, rear, left, and right walls 142, 144, 146, 148 (see FIG. 5 ) of the lid 140. Specifically, the depth 252 of the cover 234 may be between about 75% and about 100% of the external depth 162, or between about 85% and about 95% of the external depth 162, or about 92% of the external depth 162 of the container 100. In some examples, the depth 256 and/or the width (not shown) of the plug 236 are approximately equal to or larger than the internal depth 246 and the internal width (not shown), respectively, of the interior volume 206. Thus, when the lid is in the closed position and the plug 236 is partially inserted into the interior volume 206, larger profile of the plug 236 creates an interference fit with the liner 104, thereby creating the seal between the interior volume 206 and the ambient environment. In some aspects, the depth 256 of the plug 236 may be between about 90% and about 110% of the internal depth 246, or between about 100% and about 105% of the internal depth 246, or about 100% of the internal depth 246 of the interior volume 206.
Referring now to FIG. 10 , a detail, cross-sectional view is illustrated of an upper corner, e.g., an upper left-hand corner, of the container 100. As discussed above, the shell 102 and the liner 104 are coupled to one another at the hinge 180 (see FIG. 3 ) and the first closure 138. In particular, the outer and inner base layers 122, 124 are coupled to the first half 208A of the first closure 138, and the outer and inner lid layers 222, 224 are coupled to the upper or second half 208B of the first closure 138. Further, the first strip 190 of material couples the top wall 150 of the lid 140 to the second half 208B of the first closure 138, thereby forming the first joint 196A. In addition, the top wall 150 includes the first ridge 192 that is formed integrally therewith.
In some aspects, the lid 140 further includes a top or first support layer 260 that is coupled to a bottom side of the top wall 150, i.e., disposed between the top wall 150 and the first lid insulation layer 226A. The first support layer 260 is configured to reinforce the top wall 150 and increase the durability and/or rigidity of the shell 102. For example, the first support layer 260 is used to form the first ridge 192 and the logo 198 (see FIG. 5 ) in the top wall 150, meaning that the first ridge 192 and the logo 198 (see FIG. 5 ) are also formed in the first support layer 260. Moreover, it is contemplated that the first support layer 260 can be constructed from a variety of different materials with different material properties. For example, the first support layer 260 may be more or less rigid, elastic, strong, ductile, hard, brittle, tough, resilient, and/or stiff than the outer lid layer 222, i.e., the shell 102. It is contemplated that the first support layer 260 may be constructed from an EVA-Solid-Sponge (“ESS”) material, an EVA foam, polyurethane, polyether, an olefin block copolymer, a thermoplastic material (e.g., a thermoplastic polyurethane, a thermoplastic elastomer, a thermoplastic polyolefin, etc.), and/or a supercritical foam. In some examples, the first support layer 260 is formed, for example, using of an expansion press, an injection machine, a pellet expansion process, a cold foaming process, a compression molding technique, die cutting, or any combination thereof.
Referring now to FIG. 11 , a detail cross-sectional view is illustrated of a lower corner, e.g., a lower right-hand corner, of the container 100. As discussed above, the second strip 200 of material extends around the outer periphery of the bottom wall 120 and is configured as a corner joint to couple the front, rear, left, and right walls 112, 114, 116, 118 of the base 110 to the bottom wall 120 of the base 110. Further, the bottom wall 120 includes the second ridge 202 and/or the logo 204 (see FIG. 6 ) that are formed integrally therewith. In some aspects, the base 110 further includes a bottom or second support layer 262 that is coupled to a top side of the bottom wall 120, i.e., disposed between the bottom wall 120 and the base insulation layer 126. The second support layer 262 is configured to reinforce the bottom wall 120 and increase the durability and/or rigidity of the shell 102. For example, the second support layer 262 is used to form the second ridge 202 and the logo 204 (see FIG. 6 ) in the bottom wall 120, meaning that the second ridge 202 and the logo 204 (see FIG. 6 ) are also formed in the second support layer 262. Moreover, it is contemplated that the second support layer 262 can be constructed from a variety of different materials with different material properties. For example, the second support layer 262 may be more or less rigid, elastic, strong, ductile, hard, brittle, tough, resilient, and/or stiff than the outer base layer 122, i.e., the shell 102. It is contemplated that the second support layer 262 may be constructed from an EVA-Solid-Sponge (“ESS”) material, an EVA foam, polyurethane, polyether, an olefin block copolymer, a thermoplastic material (e.g., a thermoplastic polyurethane, a thermoplastic elastomer, a thermoplastic polyolefin, etc.), and/or a supercritical foam. In some examples, the second support layer 262 is formed, for example, using of an expansion press, an injection machine, a pellet expansion process, a cold foaming process, a compression molding technique, die cutting, or any combination thereof.
FIG. 12 depicts a flowchart illustrating a method 300 for assembling the container 100. While the example process is described with reference to the flowchart illustrated in FIG. 12 , various other methods of assembling the container 100 may alternatively be used. For example, the order of execution of the blocks may be rearranged, changed, eliminated, and/or combined to perform the method 300. Step 302 of the method 300 includes providing the shell 102, the liner 104, the insulation layers 126, 226, and the first closure 138. In some aspects, providing the shell 102, the liner 104, and the insulation layers 126, 226 includes forming or cutting sheets of material(s) to size. For example, multiple rectangular insulation layers are cut from a large sheet of insulative material, e.g., open-or closed-cell foam, or each of the insulation layers 126, 226 are formed as integral one-piece sheets.
Step 304 of the method 300 includes forming the base 110 and the lid 140 to define the cavity 108. For example, opposing sides of the shell 102, e.g., the outer base layer 122, the first strip 190 of material, the second strip 200 of material, and/or the outer lid layer 222, are coupled to one another to one another along a seam, e.g., the seam 184, to form the rectangular shape of the container 100, the base 110, and/or the lid 140. In some aspects, providing the shell 102 also includes forming, e.g., molding, stamping, casting, etc., the bottom wall 120 and/or the top wall 150 to include the ridges 192, 202 and/or the logos 198, 204, respectively, thereon. In some examples, step 304 further includes coupling the second strip 200 of material to the shell 102, e.g., the outer base layer 122, and the bottom wall 120 of the base 110 along an outer periphery of the bottom wall 120. In this way, the second strip 200 forms the second joint 196B between the front, rear, left, and right walls 112, 114, 116, 118 of the base 110 and the bottom wall 120 of the base 110.
Step 306 of the method 300 includes positioning or slipping the insulation layers 126, 226 within the cavity 108 of the shell 102, and step 308 of the method 300 includes positioning the liner 104 within the cavity 108 of the shell 102 to cover the insulation layers 126, 226. In particular, the base insulation layer 126 is placed or slipped into the cavity 108 before the inner base layer 124 is inserted into the cavity 108, meaning that the base insulation layer 126 is positioned in between the outer and inner base layers 122, 124. For example, the base insulation layer 126 is formed as a one-piece sheet which is scored to conform to the shape of the outer base layer 122, or the base insulation layer 126 is provided as an assembly with multiple insulation sheets that correspond to each of the walls 112, 114, 116, 118, 120 of the base 110. In some aspects, positioning the liner 104 within the cavity 108 further includes forming the seat 212 atop the base insulation layer 126 proximate to the first end 128 of the base 110. Thus, in some examples, individual sheets (not shown) of the liner 104 are positioned to cover the insulation layers 126, 226 and define the interior of the container 100, e.g., the seat 212, the cover 234, and the plug 236. Further, the lid insulation layers 226 are positioned in between the outer and inner lid layers 222, 224, meaning that the lid insulation layers 226 are positioned proximate to the underside 232 of the lid 140. In some examples, step 306 further includes positioning the first and second support layers 260, 262 proximate the top wall 150 and the bottom wall 120, respectively.
Step 310 of the method 300 includes coupling, e.g., welding, the outer and inner base layers 122, 124 to the first closure 138 to seal the base insulation layer 126 from the ambient environment and define the interior volume 206. For example, the outer and inner base layers 122, 124 are coupled to opposing sides of the first half 208A of the first closure 138 at the first end 128 of the base 110. In some aspects, step 310 further includes welding individual sheets of the inner base layer 124 together along one or more seams, e.g., the seat seams 214, to form the seat 212 atop the base insulation layer 126 proximate to the first end 128 of the base 110. Accordingly, the base insulation layer 126 is secured between the outer base layer 122 and the inner base layer 124, although it is contemplated that the base insulation layer 126 may be a floating insulation layer that is not coupled to the outer and/or inner base layers 122, 124.
Step 312 of the method 300 includes coupling, e.g., integrally molding, welding, adhering, etc., the first strip 190 of material to the first closure 138 and the top wall 150 of the lid 140 along an outer periphery of the lid 140. In particular, the first strip 190 is coupled to a first side 210A of the second half 208B of the first closure 138 to form the front, rear, right, and left walls 142, 144, 146, 148 of the lid 140. Thus, the first strip 190 forms the first joint 196A between the top wall 150 of the lid 140 and the first closure 138. Step 314 of the method 300 includes coupling the liner 104, e.g., the inner lid layer 224, to the first closure 138 to seal the lid insulation layers 226 from the ambient environment, and define the cover 234 and the plug 236. In particular, the inner lid layer 224 is coupled to the second side 228B of the second half 208B of the first closure 138. In some aspects, the lid insulation layers 226 are not directly coupled to the underside 232 of the lid 140, instead being covered by the inner lid layer 224 which in turn is coupled to the underside 232 of the lid 140. For example, the first lid insulation layer 226A is positioned between the underside 232 of the lid 140 and one side the partition layer 248 of the inner lid layer 224, and the second lid insulation layer 226A is positioned on the other side of the partition layer 248 to abut the interior volume 206 of the container 100. Thus, in some aspects, the inner lid layer 224 includes multiple components that are coupled, e.g., welded, to one another to cover the lid insulation layers 226, i.e., to define the cover 234 and the plug 236.
Referring now to FIGS. 13-21 , various aspects of an implementation of a container 400 are depicted, according to another aspect of the present disclosure. In this embodiment, elements that are shared with—i.e., that are structurally and/or functionally identical or similar to—elements present in the container 100 are represented by like reference numerals in the 400 and/or 500 series. In the interest of brevity, some features of this embodiment that are shared with the embodiment of FIGS. 1-12 are numbered or labeled in FIGS. 13-21 but are not discussed in the specification. In some examples, the container 400 is provided as a backpack-style container, i.e., a container that is configured to be carried as a backpack.
Referring to FIGS. 13-18 , the container 400 comprises an outer portion or shell 402 and an inner portion or liner 404 (see FIG. 19 ) that is configured to fit within a cavity 408 defined by the shell 402. The shell 402 includes a base 410 defining a front wall 412, a rear wall 414, a left wall 416, and a right wall 418, each of which extend upwardly from a bottom wall 420 to form a perimeter of the base 410. In some aspects, each of the front, rear, left, right and bottom walls 412, 414, 416, 418, 420 of the base 410 are substantially planar walls that meet one another at curved corners of the base 410. The base 410 of the container is configured as a base assembly that includes an outer base layer 422 defined by the shell 402, an inner base layer 424 defined by the liner 404 (see FIG. 19 ), and a base insulation layer 426, which are best shown and described in relation to FIG. 21 . Further, the base 410 has a top or first end 428 and a bottom or second end 430 that is opposite the first end 428. The container 400 also defines a y-axis 432 that extends between the first end 428 and the second end 430, a z-axis 434 that extends between the front wall 412 and the rear wall 414 in a direction that is perpendicular to the y-axis 432, and an x-axis 436 that extends between the left wall 416 and the right wall 418 in a direction that is perpendicular to the y-axis 432 and the z-axis 434. Further, a center of gravity (CG) of the container 400, when unloaded, is located approximately centrally within the cavity (see FIG. 19 ) such that the CG is coaxial with the axes 432, 434, and 436, e.g., located where the y-axis 432 intersects the z-axis 434 and the x-axis 436. In some examples, the CG is spaced farther away from the second end 430 than the first end 428 with respect to the y-axis 432, as will be discussed below in greater detail. When the container 400 is loaded, the CG can be displaced in one or more directions, so as to be offset with respect to one or more of the y-axis 432, the z-axis 43, and the x-axis 436.
Referring specifically to FIG. 13 , the container 400 includes a first closure 438 at the first end 428 of the base 410 that extends along the periphery of the top of the front, left, and right walls 412, 416, 418 of the base 410, and at least partially along the periphery of the top of the rear wall 414 of the base 410. The first closure 438 is integral with the structure of the base 410 and serves as a connection point between the base 410 and a moveable lid 440, as discussed above. For example, the first closure 438 may be a zipper, one or more rail-type closures, hook and loop fasteners, tabs, interference fitting closures, interlocking closures, magnetic closures, waterproof closures, and/or any other suitable type of fastener, without departing from the scope of the present disclosure.
In some aspects, the lid 440 is configured as a lid assembly and includes a front wall 442, a rear wall 444, a left wall 446, and a right wall 448, each of which extend downwardly from a top wall 450. The lid 440 is movably coupled to the base 410, such that when the lid 440 is in a closed position, i.e., when the lid 440 is secured to the base 410 via the first closure 438, each of the walls 412, 414, 416, 418 of the base 410 is adjacent and flush with the corresponding walls 442, 444, 446, 448 of the lid 440, respectively. In some examples, the container 400 further includes one or more pockets 452, shoulder straps 454, and/or side handles 456, as will be discussed in greater detail below.
In some aspects, however, the container 400 differs from the container 100. Referring specifically to FIG. 14 , one or more loops 458 of material are coupled to the front wall 442 of the container 400 to, for example, allow items, e.g., clips, attachment rings, rope, paracord, etc., to be attached to the front wall 442. In particular, the loops 458 are coupled, e.g., stitched, adhered, and/or welded, to patches (not shown) that are covered by the shell 402 and/or coupled to an interior (not shown) of the shell 402. In some examples, the loops 458 are arranged in rows and/or columns, with a single row or column of the loops 458 being disposed on a single patch (not shown). While FIG. 14 illustrates the loops 458 as being disposed on the front wall 442, it is contemplated that the loops 458 may be coupled to the base 110 at a variety of different locations, such as, e.g., the rear, left, and right walls 414, 416, 418 of the container 400. Further, the loops 458 may be formed of webbing, such as, e.g., nylon webbing, or other suitable materials that may include, among others, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, or rope.
Referring to FIGS. 14 and 15 , front and side elevational views, respectively, are illustrated of the container 400. It is contemplated that aspects relating to the right wall 418 of the base 410 as described herein are also applicable to the left wall 416 of the base 410. Various dimensions of the container 400 are shown, including an external height 460 of the container 400, an external depth 462 of the container 400, and an external width 464 of the container 400. Each of the external height, depth, and width 460, 462, 464 of the container 400 are measured along the y-axis 432, the z-axis 434, and the x-axis 436, respectively. In some aspects, the external depth 462 of the container 400 may be between about 25% and about 75% of the external height 460, or between about 40% and about 60% of the external height 460, or between about 40% and about 50% of the external height 460, or about 48% of the external height 460 of the container 400. In some aspects, the external width 464 of the container 400 may be between about 50% and about 100% of the external height 460, or between about 60% and about 80% of the external height 460, or between about 70% and about 80% of the external height 460, or about 74% of the external height 460 of the container 400.
Still referring to FIGS. 14 and 15 , the container 400 includes a first pocket 452A, e.g., a front pocket, on the front wall 412 of the base 410, and the first pocket 452A has a second closure 466 to seal an interior thereof from the ambient environment. In some aspects, the first pocket 452A is integrally formed with the front wall 412 of the base 410, or the first pocket 452A is coupled to the front wall 412 of the base 410 via stitching, glue, welding, and/or another suitable fastening technique. It is contemplated that the first pocket 452A may be formed in the shell 402 so as to be flush with front wall 412 of the base 410, or the first pocket 452A can be formed as an external pocket on the front wall 412. In the illustrated non-limiting example, the first pocket 452A is a substantially rectangular, external pocket that protrudes outward from the front wall 412 of the base 410, e.g., in a direction along the z-axis 434, so as to define at least a left side 468, a top side 470, and a right side 472. The second closure 466 extends at least partially around a periphery of the first pocket 452A, i.e., along portions of the left side 468, the top side 470, and the right side 472. Accordingly, the first pocket 452A can be loaded from above or from the side(s) by selectively opening the second closure 466 along the left side 468, the top side 470, and/or the right side 472. In some aspects, the second closure 466 is substantially similar to the first closure 438. For example, the second closure 466 may be a zipper, waterproof closure, rail-type closures, hook and loop fasteners, tabs, interference fitting closures, interlocking closures, magnetic closures, and/or any other suitable type of fastener without departing from the scope of the present disclosure.
The first pocket 452A is configured to hold a variety of objects, such as, e.g., cell phones, wallets, small purses, car keys, beverage containers, and/or other objects sized and shaped accordingly. In some aspects, one or more compartments (not shown), e.g., mesh pockets, flaps defined by the shell 402, and/or elastic bands, are located within the first pocket 452A to help organize any objects contained therein. The first pocket 452A can be provided with insulation (not shown), such as, e.g., a thickened wall material, insulative material embedded within or lining inside one or more walls of the first pocket 452A. Further, because the first pocket 452A is coupled to the front wall 412, the first pocket 452A is separated from the internal cavity 408, meaning that the internal cavity 408 and the first pocket 452A are not in fluid communication with one another. Separating the internal cavity 408 from the first pocket 452A prevents fluids and/or heat from being exchanged therebetween, which in turn allows the first pocket 452A to remain dry when fluids, e.g., water from melting ice, are disposed within the internal cavity 408. In this way, the first pocket 452A is configured to protect objects contained therein from fluid and/or heat exposure.
Referring now to FIG. 15 , the container 400 further includes second pockets 452B located on the left wall 416 of the base 410 (see FIG. 14 ) and the right wall 418 of the base 410. In some aspects, a second pocket 452B is integrally formed with the right wall 418 of the base 410, or the second pocket 452B is coupled to the right wall 418 of the base 410 via stitching, glue, welding, and/or another suitable fastening technique. It is contemplated that the second pocket 452B may be formed in the shell 402 so as to be flush with right wall 418 of the base 410, or the second pocket 452B can be formed as an externally protruding pocket. In the illustrated non-limiting example, the second pocket 452B is defined, in part, by a side panel 474 that is coupled to the right wall 418. During manufacture of the container 400, a portion of the shell 402 that defines the right wall 418 is removed to form a cutout 476 in the right wall 418, and the side panel 474 is attached to an inner surface (not shown) of the shell 402 to cover the cutout 476. In this way, the side panel 474 provides an outline for the second pocket 452B by creating a visibly recessed area SA1 within the right wall 418, which in turn increases the capacity of the second pocket 452B and enhances the aesthetic appeal of the base 410 when viewed from the side. In some examples, the side panel 474 is made of the same material as the shell 402, e.g., neoprene, polyester, cotton fabric, mesh fabric, leather, plastics, rubber, nylon, molded EVA (Ethylene Vinyl Acetate, a synthetic fabric, such as polyester and/or nylon fabric, thermoplastic polyurethane, etc.
In some examples, the side panel 474 and the cutout 476 are trapezoidal in shape such that a top boundary 478 of the second pocket 452B slopes downward as it extends toward the rear wall 414. That is, the top boundary 478 of the second pocket 452B defines an angle 480 with the z-axis 434, and the angle is between about 0 degrees and about 60 degrees, or between about 15 degrees and about 45 degrees, or about 30 degrees. However, it is contemplated that side panel 474 and/or the cutout 476 can have any suitable shape or combination of shapes, e.g., a quadrilateral, a circle, a triangle, etc. In some examples, the recessed area SA1 defined by the side panel 474 and the cutout 476 comprises between about 20% and about 80% of an area SA2 defined by the right wall 418, or between about 20% and about 60% of the area SA2 of the right wall 418, or between about 30% and about 50% of the area SA2 of the right wall 418, or about 40% of the area SA2 of the right wall 418.
With continued reference to FIG. 15 , the second pocket 452B is further defined by a mesh net 482 that covers at least a portion of the recessed area SA1 defined by the side panel 474. The net 482 is coupled to the side panel 474 along a periphery of the recessed area SA1, and the net 482 is open on a side facing the lid 440. In particular, an upper edge of the net 482 includes an elastic band 484 that is attached, e.g., adhered, welded, sewn, etc., to the side panel 474 at anchor points 486 disposed on opposite sides of the second pocket 452B, i.e., a first side adjacent the front wall 412 and a second side adjacent the rear wall 414. The anchor points 486 are covered by the shell 102, which enhances the aesthetic appeal of the right wall 418 and increases the strength of the attachment between the side panel 474 and elastic band 484. In some examples, the mesh net 482 is elastic and is configured to stretch to accommodate items, e.g., beverage containers, cell phones, wallets, etc., that are placed in the second pocket 452B. Accordingly, the net 482 may be formed of any suitable elastic material such as, e.g., nylon, braided elastic, woven elastic, knitted elastic, spandex, etc. In other examples, the second pocket 452B is defined by flaps of the shell 402, straps, and/or a non-mesh elastic sheet.
Still referring to FIG. 15 , the container 400 further includes side handles 456 coupled to the sides, e.g., the left wall 416 (see FIG. 14 ) and the right wall 418 of the container 400. Specifically, the side handles 456 are located approximately centrally between the front wall 412 and the rear wall 414. Further, the side handles 456 are located closer to the lid 440 than the bottom wall 420 (see FIG. 18 ), although it will be understood that the side handles 456 can be coupled to the container 400 at any suitable position on the base 410. In the illustrated example, the side handles 456 are positioned approximately centrally between the front wall 412 and the rear wall 414 to provide a lifting point that is approximately coplanar with the CG of the container 400 in an unloaded, e.g., empty, configuration, which allows the container 400 to be picked up in a controlled manner by minimizing weight imbalance. For example, the central lifting point provided by the side handles 456 minimizes potential imbalances created by loading the container 400 on one side, e.g., a load skewed toward one of the walls 412, 414, 416, 418 of the container 400. In some examples, the side handles 456 may be offset toward the front wall 412 or the rear wall 414 to account for typical loading configurations such as, e.g., positioning lighter object and/or loads toward the front wall 412, and heavier objects and/or loads toward the rear wall 414. Alternatively, the side handles 456 may be offset at an angle with respect to the z-axis 434, meaning that the side handles 456 can define a diagonal or slanted profile on the left and right walls 416, 418. This allows a user to tilt the second end 430 of the base 410, thereby preventing the container 400 from contacting the user's legs while walking and carrying the container 400 by the side handles 456. Accordingly, the side handles 456 are located on the left and right walls 416, 418 to make the container 400 easy and comfortable to carry.
In some aspects, the side handles 456 are coupled to the container 400 via patches (not shown) that are attached to or formed integrally with the shell 402. In some aspects, the patches (not shown) are coupled to the exterior of the shell 402 such that the patches (not shown) are visible, or the patches (not shown) are covered by, i.e., disposed beneath, flaps 488 formed in the shell 402. It is contemplated that the side handles 456 may be formed of webbing, such as, e.g., nylon webbing, or other materials that may include, among other, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, or rope.
Referring now to FIG. 16 , a rear elevation view is illustrated of the container 400. As discussed above, the container 400 is a backpack-style container that is configured to be carried on a user's back. Accordingly, the container 400 includes one or more shoulder straps 454 for carrying the container 400. In the illustrated non-limiting example, the container 400 includes a first shoulder strap 454A, e.g., a left-side strap, and a second shoulder strap 454B, e.g., a right-side strap, and the shoulder straps 454 are coupled to the rear wall 414. In particular, distal ends 490 of the shoulder straps 454 are directly coupled, e.g., adhered, sewn, and/or welded, to the rear wall 414, or the distal ends 490 of the shoulder straps 454 are coupled to patches (not shown) e.g., patches that are attached to or formed integrally with the shell 402 and covered by, i.e., disposed beneath, the shell 402. In the illustrated non-limiting example, upper distal ends 490A of the shoulder straps 454 are directly coupled to the rear wall 414, while lower distal ends 490B of the shoulder straps 454 are not directly coupled to the rear wall 414, although it is contemplated that the lower distal ends 490B may be coupled to the rear wall 414 in other examples.
Further, the shoulder straps 454 are coupled to load stabilizer straps 492, which in turn are coupled, e.g., adhered, sewn, and/or welded, to the rear wall 414 at attachment points 494 (see FIG. 15 ). In some aspects, the attachment points 494 (see FIG. 15 ) define locations on the rear wall 414 at which the load stabilizer straps 492 are coupled to patches (not shown) e.g., patches that are attached to or formed integrally with the shell 402 and covered by, i.e., disposed beneath, the shell 402. The load stabilizer straps 492 are also coupled to slip buckles 496, which are configured to allow the load stabilizer straps 492 to be adjustable, e.g., to be tightened and/or loosened, to change the load distribution and/or the CG of the container 400. For example, tightening a load stabilizer strap 492 with a slip buckle 496 shortens a distance between an upper distal end 490A of the corresponding shoulder strap 454 and the rear wall 414, which in turn helps to keep the rear wall 414 of the base 410, e.g., the first end 428 of the base 410, tight against a user's back when the container 400 is worn. Put another way, tightening the load stabilizer strap 492 moves the CG of the container 400 closer to the user's back, which helps to mitigate potential weight imbalances and makes the container 400 more comfortable to wear. In the illustrated non-limiting example, upper load stabilizer straps 492A are directly attached to the rear wall 414 at upper attachment points 494A (see FIG. 15 ), and lower load stabilizer straps 492B are coupled to strap loops 498 (see FIG. 15 ) that are directly coupled, e.g., adhered, sewn, and/or welded, to the rear wall 414 at lower attachment points 494B located at the second end 430 of the base 410. In some aspects, the strap loops 498 (see FIG. 15 ) are formed of materials that may include, for example, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, and/or rope.
With continued reference to FIG. 16 , the container 400 further includes a chest strap 500 that is configured to hold the shoulder straps 454 within a maximum distance from one another when fastened. The chest strap 500 is coupled to each of the shoulder straps 454 and extends therebetween in a direction that is substantially parallel with respect to the x-axis 436. In some examples, the chest strap 500 includes a first fastener 502, e.g., one or more buckles, magnets, hook-and-loop fasteners, etc., that allows a first half 504A of the chest strap 500 to be removably coupled to a second half 504B of the chest strap 500. In some examples, each half 504 of the chest strap 500 is slidably coupled to a rail 506 disposed on the corresponding shoulder strap 454, the rail 506 extending longitudinally along at least a portion of the corresponding shoulder strap 454. Thus, the chest strap 500 is slidable along the shoulder straps 454 to accommodate a specific size and/or shape of a user's chest, which enhances comfort when a user is wearing the container 400. In some examples, each rail 506 defines a substantially arcuate path along each respective shoulder strap 454. Further, it is contemplated that the rails 506 may be formed of any suitable material, such as, e.g., polypropylene, neoprene, polyester, Dyneema, Kevlar, plastics, rubber, metal, etc.
Relatedly, a shoulder strap 454, e.g., the first shoulder strap 454A, defines a strap length 508 that is measured between the upper distal end 490A and the lower distal end 490B. In some examples, a rail 506 disposed on the shoulder strap 454 defines a rail length 510 that is between about 25% and about 100% of the strap length 508, or between about 25% and about 50% of the strap length 508, or between about 30% and about 40% of the strap length 508, or about 33% of the strap length 508.
Further, the container 400 includes waist straps 512 that are directly coupled to the rear wall 414 at the lower attachment points 494B. In some aspects, a second fastener 514, e.g., one or more buckles, magnets, hook-and-loop fasteners, etc., is coupled to the waist straps 512 to allow a first waist strap 512A to be removable coupled to a second waist strap 512B. Tightening the waist straps 512 helps to keep the rear wall 414 of the base 410, e.g., the second end 430 of the base 410, tight against a users' back and/or waist when the container 400 is worn.
It is contemplated that the shoulder straps 454 and/or the waist straps 512 are formed of materials that may include, for example, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, and/or rope. In some examples, the shoulder straps 454 and/or the waist straps 512 include one or more layers of padding 516 on inside surfaces thereof, e.g., surfaces of the shoulder straps 454 and/or the waist straps 512 that are configured to contact a user when the container 400 is worn, to further enhance comfort. In some examples, the padding 516 is made of nylon, a thermoplastic material, e.g., polyurethane (PU), and/or an ethylene-vinyl acetate (EVA), copolymers thereof, EVA-Solid-Sponge (“ESS”) material, an EVA foam, polyurethane, polyether, an olefin block copolymer, a thermoplastic material, e.g., a thermoplastic polyurethane, a thermoplastic elastomer, a thermoplastic polyolefin, etc., a closed-cell foam, an open-celled foam, a dual-density foam, a supercritical foam, and/or any combination thereof.
Still referring to FIG. 16 , the rear wall 414 is at least partially covered by a rear sheet 518 of material, and a rear panel 520 is coupled to the rear sheet 518. During manufacture of the container 400, the rear sheet 518 is coupled to the rear wall 414 via, e.g., welding, adhering, stitching, etc., to over one or more patches (not shown) that are also coupled to the rear wall 414. For example, the rear sheet 518 covers the patches (not shown) corresponding to the attachment points 494 (see FIG. 15 ). In some aspects, the rear sheet 518 is inset from edges of the rear wall 414, e.g., boundaries of the rear wall 414 adjacent the left, right, and the bottom wall 420, as well as a boundary between the rear wall 414 and the top wall 450 of the lid 440. Put another way, the rear sheet 518 is inset from a periphery of the rear wall 414. In the illustrated non-limiting example, the rear sheet 518 includes projections 522 that correspond in shape to patches, e.g., square patches (not shown), that define the upper attachment points 494A (see FIG. 15 ). In some aspects, the projections 522 are coupled to the rear wall 414 of the base 410 and the rear wall 444 of the lid 440, meaning that the projections 522 extend over a hinge 524 of the container 400.
In some examples, the rear sheet 518 defines an area SA3 that is between about 50% and about 100% of an area SA4 defined by the rear wall 414, or between about 75% and about 100% of the area SA4 of the rear wall 414, or between about 80% and about 90% of the area SA4 of the rear wall 414, or about 85% of the area SA4 of the rear wall 414, or greater than about 50% of the area SA4 of the rear wall 414, or greater than about 75% of the area SA4 of the rear wall 414. In some aspects, the rear sheet 518 is made of the same material as the shell 402, e.g., neoprene, polyester, cotton fabric, mesh fabric, leather, plastics, rubber, nylon, molded EVA (Ethylene Vinyl Acetate, a synthetic fabric, such as polyester and/or nylon fabric, thermoplastic polyurethane, etc.
As discussed above, the rear panel 520 is coupled to the rear sheet 518, the rear panel 520 providing enhanced rigidity and support to the rear wall 414 of the base 410. In some examples, the rear panel 520 defines a generally rectangular shape that is inset from a periphery of the rear sheet 518, although it is contemplated that the rear panel may be provided in any suitable shape or combination of shapes. To increase the rigidity of the rear wall 414, the rear panel 520 is made of a suitably rigid material, e.g., plastics, metal, wood, a composite or one or more layers of fibers, and/or any combination thereof. In some examples, the rear panel 520 is made of a more rigid material than the rear sheet 518.
Further, a flange 526 extends entirely around the rear panel 520. In some aspects, the flange 526 is also coupled to the rear wall 414 via, e.g., stitching, to further secure the rear panel 520 to the rear wall 414. A carry handle 528 is coupled to the rear wall 414 along a portion of the flange 526 that is proximate the first end 428 of the base 410. In some examples, the flange 526 and/or the carry handle 528 are formed of webbing, such as, e.g., nylon webbing, or other materials that may include, among other, polypropylene, neoprene, polyester, Dyneema, Kevlar, cotton fabric, leather, plastics, rubber, or rope. In addition, back padding 530 is disposed on an outward-facing side of the rear panel 520 to further enhance user comfort when the container 400 is being worn on a user's back. In some examples, the back padding 530 defines a plurality of padding sections 532 arranged in one or more columns and/or rows, the padding sections 532 decreasing in area from the second end 430 of the base 410 to the first end 428 of the base 410. However, it is contemplated that the back padding 530 may be arranged in any suitable pattern, e.g., curved sections, differently sized sections, uniformly sized sections, etc. In some aspects, the back padding 530 comprises mesh and/or foam to promote airflow therethrough, which in turn helps to cool down a user's back when wearing the container 400. For example, the back padding 530 may comprise one or more of nylon, a thermoplastic material, e.g., PU, and/or an EVA, copolymers thereof, ESS material, an EVA foam, polyurethane, polyether, an olefin block copolymer, a thermoplastic material, e.g., a thermoplastic polyurethane, a thermoplastic elastomer, a thermoplastic polyolefin, etc., a closed-cell foam, an open-celled foam, a dual-density foam, a supercritical foam, and/or any combination thereof.
Still referring to FIG. 16 , the rear wall 414 of the base 410 and the rear wall 444 of the lid 440 define the hinge 524, e.g., a living hinge, of the container 400, which defines a hinge axis 534 extending between an interface of the base 410 and the lid 440 in a direction that is parallel with respect to the x-axis 436. Accordingly, the lid 440 can be rotated about the hinge axis 534 when, for example, the lid 440 is opened or closed. In some aspects, the hinge 524 is formed by the shell 402 and the inner liner 404 (see FIG. 19 ), meaning that the hinge 524 serves as a connection point between the shell 402 and the liner 404 (see FIG. 19 ).
Referring now to FIG. 17 , the top wall 450 of the lid 440 is substantially similar to the top wall 150 of the lid 140 of the container 100 illustrated in FIGS. 1-12 , in some aspects. For example, the top wall 450 of the lid illustrated in FIG. 17 is rectangular-shaped or square-shaped and includes an upper or first strip 536 of material and an upper or first ridge 538. Specifically, the first strip 536 extends around the outer periphery of the lid 440 and is configured to protect and reinforce the lid 440 by increasing the rigidity of the lid 440 and serving as a corner support and/or joint. That is, the first strip 536 wraps over the peripheral edge of the top wall 450 so as to couple the top wall 450 with each of the walls 442, 444, 446, 448 of the lid 440. In some examples, the first strip 536 defines each of the walls 442, 444, 446, 448 of the lid 440, and the first strip 536 forms an upper or first joint 540A between the top wall 450 and the first closure 438 (see FIG. 21 ). In some aspects, the first strip 536 is formed of a similar material as the shell 402, e.g., polyester fabric, or the first strip 536 is constructed of a more rigid material than the material of the shell 402.
In addition, the first ridge 538 is inset from the peripheral edge of the top wall 450 and defines a curved or semi-circular profile. Further, the first ridge 538 is formed integrally with the top wall 450 of the lid 440 and extends upwardly, i.e., along the y-axis 432 (see FIG. 14 ), therefrom. In some examples, the first ridge 538 is formed during manufacture of the lid 440 using, e.g., injection molding, blow molding, stamping, die-casting, etc.
Still referring to FIG. 17 , the container 400 further includes a holding system 542 on the top wall 450 of the lid 440. The holding system 542 includes additional strips 544 of material that are coupled to the top wall 450, e.g., adhered, stitched, and/or welded, and an elastic member 546 that extends between the additional strips 544. In particular, the additional strips 544 are positioned on the top wall 450, inset with respect to the first ridge 538 and disposed along opposing sides of the lid 440, e.g., the front wall 442 and the rear wall 444, or the left wall 446 and the right wall 448. In the illustrated non-limiting example, the additional strips 544 comprise a second strip 544A of material and a third strip 544B of material that are inset from opposing sides of the lid 440, e.g., the second strip 544A inset from the front wall 442, and the third strip 544B inset from the rear wall 444. However, it is contemplated that the holding system 542 may include fewer or additional strips that are disposed along an inside periphery of the first ridge 538 in other examples. In some aspects, each additional strip 544 is welded to the top wall 450 to form a strip hinge 548 therebetween, which allows a portion of each additional strip 544 to pivot in the YZ plane (not shown). Further, in some examples, each additional strip 544 is constructed of neoprene, polyester, cotton fabric, mesh fabric, leather, plastics, rubber, nylon, metal, and/or molded EVA.
Each additional strip 544 of material includes one or more eyelets 550 therealong, and the elastic member 546 extends through the eyelets 550. The eyelets 550 are spaced, e.g., uniformly spaced, along each additional strip 544 such that the eyelets 550 defined by the second strip 544A mirror the eyelets 550 defined by the third strip 544B. For example, the second strip 544A includes a first eyelet 550A, a second eyelet 550B, and a third eyelet 550C, and the third strip 544B includes a fourth eyelet 550D that mirrors the first eyelet 550A, a fifth eyelet 550E that mirrors the second eyelet 550B, and a sixth eyelet 550F that mirrors the third eyelet 550C. Put another way, the first eyelet 550A is collinear with the fourth eyelet 550D in a direction that is substantially parallel with respect to the y-axis 432, the second eyelet 550B is collinear with the fifth eyelet 550E in a direction that is substantially parallel with respect to the y-axis 432, and the third eyelet 550C is collinear with the sixth eyelet 550F in a direction that is substantially parallel with respect to the y-axis 432. However, it is contemplated that each additional strip 544 may include additional or fewer eyelets 550, e.g., two, three four, five, six, etc., than illustrated in the non-limiting example. In some examples, the eyelets 550 are integral with the additional strips 544 such that a medially extending portion of one of the additional strips 544, e.g., the second strip 544A, is folded over itself and welded to form a single eyelet 550, although it is contemplated that the eyelets 550 may be provided as separate components, e.g., plastic or metal eyelets, that are coupled to the additional strips 544 in other examples.
In some aspects, the elastic member 546 extends between the second strip 544A and the third strip 544B, through the eyelets 550, in an alternating, e.g., zig-zag, pattern to define the holding system 542. Still referring to the non-limiting example illustrated in FIG. 17 , a first portion 552A, e.g., a first half, the elastic member 546 extends from the first eyelet 550A to the fifth eyelet 550E, and from the fifth eyelet 550E to the third eyelet 550C. That is, the first portion 552A of the elastic member 546 extends diagonally from the second strip 544A to the third strip 544B before extending diagonally back to the second strip 544A from the third strip 544B. Further, the first portion 552A of the elastic member 546 extends through the third eyelet 550C and into a locking mechanism 554, which maintains tension in the elastic member 546. Correspondingly, a second portion 552B, e.g., a second half, of the elastic member 546 extends from the fourth eyelet 550D to the second eyelet 550B, and from the second eyelet 550B to the sixth eyelet 550F. That is, the second portion 552B of the elastic member 546 extends diagonally from the third strip 544B to the second strip 544A before extending diagonally back to the third strip 544B from the second strip 544A. Further, the second portion 552B of the elastic member 546 extends through the sixth eyelet 550F and into the locking mechanism 554.
In some examples, the first and second portions 552 of the elastic member 546 cross over one another to define intersection points 556 along the top wall 450 of the lid 440 between the second strip 544A and the third strip 544B. In the non-limiting example illustrated in FIG. 17 , the holding system 542 defines a first intersection point 556A located between the first eyelet 550A and the second eyelet 550B, and a second intersection point 556B located between the second eyelet 550B and the third eyelet 550C. However, it is contemplated the holding system 542 may define additional or fewer intersection points 556 based on the number and locations of the eyelets 550.
In this way, the holding system 542 is configured to retain objects, e.g., cell phones, wallets, small purses, trail maps, food items, and/or other objects sized and shaped accordingly, in place on top of the container 400. Specifically, such objects are held in place between the elastic member 546 and the top wall 450 by the tension of the elastic member 546, which is adjustable by actuating the locking mechanism 554. In some examples, the locking mechanism 554 is a spring-based locking mechanism, e.g., a push-button lock, a cord lock, a double hole cord lock, a wheeled cord lock, and/or any combination thereof. In some examples, the locking mechanism 554 is constructed from plastic, leather, metal, and/or any combination thereof.
Referring now to FIG. 18 , the bottom wall 420 of the base 410 is substantially similar to the bottom wall 120 of the base 110 of the container 100 illustrated in FIGS. 1-12 . For example, the bottom wall 420 of the base 410 illustrated in FIG. 18 is substantially rectangular-shaped or square-shaped and includes a lower or fourth strip 558 of material and a lower or second ridge 560 that are each coupled to the bottom wall 420 of the base 410. The fourth strip 558 mirrors the first strip 536 (see FIG. 17 ), meaning that the fourth strip 558 extends around the outer periphery of the bottom wall 420 and is configured to protect and reinforce the base 410 by forming a lower or second joint 540B between the bottom wall 420 and the front, rear, left, and right walls 412, 414, 416, 418 of the base 410 (see FIG. 14 ). In some aspects, the fourth strip 558 is formed of a similar material as the shell 402, e.g., polyester fabric, or the fourth strip 558 is constructed of a more rigid material than the material of the shell 402. In addition, the second ridge 560 mirrors the first ridge 538 (see FIG. 17 ), meaning that the second ridge 560 extends around the bottom wall 420 of the base 410 and defines a curved or semi-circular profile that is inset from the peripheral edge of the bottom wall 420, i.e., inset from the fourth strip 558. Correspondingly, the second ridge 560 elevates the container 400 above the ground or another surface when the container 400 is placed upright. In some aspects, a logo 562 is also be formed in the bottom wall 420 during the manufacture thereof. For example, the logo 562 can be molded or directly embossed into the bottom wall 420 of the base 410.
Referring R now to FIG. 19 , the container 400 is illustrated in an open position, e.g., configuration, in which the lid 440 has been rotated via the hinge 524. Thus, it will be understood that the lid 440 is capable of being rotated about the hinge axis 534 to uncover the cavity 408. In some aspects, the lid 440 can rotate at least 570 degrees via the hinge 524, or at least 480 degrees via the hinge 524. As discussed above, the hinge 524 serves as a connection point between the shell 402 and the liner 404. In particular, the shell 402 forms one side of the hinge 524, e.g., the side of the hinge along the rear wall 414 of the base 410, and the liner 404 forms an opposite side of the hinge 524, which is visible in FIG. 19 . Moreover, the liner 404 defines an innermost surface of the container 400 and an interior volume 564. In some embodiments, the liner 404 is coupled to the shell 402 by, for example, fasteners, an interference fit, glue, stitching, or welding (ultrasonic welding, RF welding, laser welding), among others.
Further, the base 410 of the container 400 includes an outer base layer 422 defined by the shell 402, an inner base layer 424 defined by the liner 404, and a base insulation layer 426 disposed therebetween (see FIG. 21 ). In some aspects, the outer base layer 422, inner base layer 424, and base insulation layer 426 (see FIG. 21 ) define planar walls and are open on one end, e.g., the top or first end 428. When the container 400 is assembled, the inner base layer 424, i.e., the liner 404, is received and secured within the base insulation layer 426, i.e., the shell 402, and the base insulation layer 426 (see FIG. 21 ) is received and secured therebetween. In some examples, the inner base layer 424 defines a seat 566 at the first end 428 of the container 400, and the seat 566 extends around an inner periphery of each of the front, rear, left, and right walls 412, 414, 416, 418 of the base 410 at the first end 428. In some aspects, the seat 566 defines a planar surface that is substantially parallel to the ZX plane (not shown), i.e., parallel to the z-axis 434 and the x-axis 436, and the seat 566 is configured to receive a corresponding structure of the lid 440 thereon when the lid 440 is in the closed position, as will be discussed below in greater detail.
Referring now to the non-limiting examples illustrated in FIGS. 19 and 20 , the lid 440 is configured as a lid assembly that includes an outer lid layer 572 defined by the shell 402, e.g., the top wall 450 of the lid 440 and the first strip 536, an inner lid layer 574 defined by the liner 404, and one or more lid insulation layers 576 (see FIG. 21 ) disposed therebetween. In some aspects, the inner lid layer 574 is an integral one-piece component, or the inner lid layer 574 includes a plurality of liner elements that are coupled to one another via, e.g., adhering, stitching, and/or welding. Moreover, a snug or tight fit is provided between the outer lid layer 572, the inner lid layer 574, and/or and the lid insulation layer(s) 576 (see FIG. 21 ), which may be an airtight or waterproof/resistant fit. For example, a sealant or compound may be applied between the liner 404 and the shell 402 to prevent ingress or egress of air, water, gases, fluids, and the like. In addition, the outer lid layer 572 and the inner lid layer 574 are coupled to one another along the hinge 524 (see FIG. 16 ) and a portion of the first closure 438 that is coupled to the lid.
In some aspects, the inner lid layer 574 and the lid insulation layer(s) 576 (see FIG. 21 ) are coupled to an underside 582 of the lid 440 and define a first portion or cover 584 and a second portion or plug 586. The cover 584 is coupled to the underside 582 of the lid 440 and protrudes therefrom opposite the top wall 450, e.g., along the y-axis 432 toward the base 410 when the lid 440 is in the closed position (see FIG. 21 ). Relatedly the plug 586 protrudes from the cover 584 opposite the top wall 450, e.g., along the y-axis 432 toward the base 410 when the lid 440 is in the closed position (see FIG. 21 ). In some examples, the cover 584 and the plug 586 define substantially rectangular profiles that are similar to the profiles of the base 410 and the lid 440. Moreover, the cover 584 and the plug 586 are aligned with one another, e.g., concentric with one another and the top wall 450 of the lid 440, along the y-axis 432 when the lid 440 is in the closed position (see FIG. 21 ). Still further, the cover 584 has a smaller area than that of the top wall 450 (see FIG. 17 ) of the lid 440, and the plug 586 has a smaller area than the area of the cover 584.
Put another way, the lid insulation layers 576 define a stepped profile that corresponds to the shape of the inner base layer 424 and the seat 566. For example, the cover 584 defines a first step surface or rim 588 around the plug 586, the rim 588 defining a planar surface that is substantially parallel to the ZX plane (not shown) when the lid is in the closed position (see FIG. 21 ). Relatedly, the plug 586 defines a second step surface or first/bottom plug surface 590 that abuts the interior volume 564 of the base 410 when the lid 440 is in the closed position (see FIG. 21 ). The bottom plug surface 590 is also a substantially planar surface that is parallel to the ZX plane (not shown) when the lid is in the closed position (not shown), meaning that the bottom plug surface 590 is parallel with respect to the rim 588. In addition, the plug 586 defines a second or side plug surface 592 around the periphery thereof, and the side plug surface 592 is configured to contact sides of the inner base layer 424 that define the interior volume 564 when the lid 440 is in the closed position (see FIG. 21 ), as will be discussed below in greater detail.
Referring now to FIG. 21 , a cross-sectional view is illustrated of the container 400 taken through line 21-21 in FIG. 14 , and the lid 440 is in the closed position. When the container 400 is assembled, the insulation layers 426, 576 are injected between the outer layers 422, 572 and the inner layers 424, 574, although it is contemplated that other configurations are also possible. In some aspects, the insulation layers 426, 576 are placed or slipped between the outer layers 422, 572 and inner layers 424, 574 during the manufacturing process. For example, the inner layers 424, 574 are received and secured within outer layers 422, 572, and the insulation layers 426, 576 are received or slipped between the outer layers 422, 572 and the inner layers 424, 574.
As discussed above, the liner 404 defines an interior volume 564 in which fluid, beverage containers, or other objects are contained, when the liner 404 is positioned within the cavity 408 of the shell 402. In some aspects, the interior volume 564 defines an internal height 594, an internal depth 596, and an internal width (not shown). In some aspects, the internal height 594 is between about 50% and about 100% of the external height 460, or between about 75% and about 90% of the external height 460, or about 88% of the external height 460 of the base 410. In some aspects, the internal depth 596 is between about 50% and about 100% of the external depth 462, or between about 60% and about 80% of the external depth 462, or about 75% of the external depth 462 of the base 410. In addition, the interior volume 564 has a volume that is between about 1 gallon (3.79 liters) and about 20 gallons (75.71 liters), or between about 1 gallon (3.79 liters) and about 5 gallons (18.93 liters), or between about 5 gallons (18.93 liters) and about 10 gallons (37.85 liters), or between about 15 gallons (56.78 liters) and about 20 gallons (75.71 liters).
In some aspects, the interior volume 564 is dimensioned so as to receive a particular quantity of beverage containers of a standard size in a vertical position and arranged in a grid-like fashion, i.e., m×n. For example, the interior volume 564 may be configured to receive twenty beverage containers arranged in a four-by-five grid, or twenty-four beverage containers arranged in a six-by-four grid, or thirty beverage containers arranged in a five-by-six grid, or thirty-two beverage containers arranged in an eight-by-four grid, or forty-eight beverage containers arranged in an eight-by-six grid, or sixty beverage containers contained in a ten-by-six grid. However, different quantities of beverage containers may be received within the interior volume 564 and may be arranged differently, such as, e.g., stacked vertically atop one another and/or disposed in horizontal positions below the first closure 438 atop of each of the walls 412, 414, 416, 418 (see FIG. 14 ) of the base 410 such that the lid 440 can be rotated about the hinge axis 534 (see FIG. 16 ) to the closed position.
Still referring to FIG. 21 , the lid inner layer 574 and the lid insulation layers 576 define the cover 584 and the plug 586 of the lid 440. In particular, the cover 584 is defined by the inner lid layer 574 and the first lid insulation layer 576A, and the plug 586 is defined by the inner lid layer 574 and the second lid insulation layer 576B. In some aspects, the lid inner layer 574 also defines a partition layer 598 disposed between the first lid insulation layer 576A and the second lid insulation layer 576B, although it is also contemplated that the lid insulation layers 576 may alternatively be in direct contact with one another.
In some examples, the lid 440 is configured to seal the interior volume 564 from a surrounding environment when the lid is in the closed position. To that end, when the lid 440 is actuated about the hinge axis 534 (see FIG. 16 ) so as to be arranged in the closed position, the rim 588 defined by the cover 584 contacts the seat 566 formed by the inner base layer 424 atop the base insulation layer 426, and the plug 586 is inserted at least partially into the interior volume 564. Put another way, plug 586 extends past the seat 566 along the y-axis 432 to abut the interior volume 564 when the lid is arranged in the closed position. Further, as illustrated in FIG. 21 , the side plug surface 592 of the plug 586 contacts the sides of the inner base layer 424 that define the interior volume 564 when the lid 440 is in the closed position, thereby sealing the interior volume 564 from a surrounding environment.
In some examples, the plug 586 forms an interference fit with the liner 404, e.g., the sides of the inner base layer 424 that define the interior volume 564 when the lid 440 is in the closed position, which in turn seals the interior volume 564 from the environment. In this way, the cover 584 and the plug 586 of the lid 440 may create a generally water-and/or air-tight seal between the lid 440 and the base 410 when the lid 440 is in the closed position. That is, the interference fit defined by the liner 404 and the plug 586 helps prevent the container 400 from leaking any fluids from within and allows for a slower rate of heat transfer between the interior volume 564 and a surrounding or ambient environment of the container 400. Thus, it will be understood that in addition to the first closure 438, the shape(s) of the cover 584 and the plug 586 provide the seal between the ambient environment and the interior volume 564. In some examples, the seal may not be a completely air-tight or water-tight.
