In one embodiment, bag 3 may be formed from similar procedures and may have characteristics similar to the bag shown in US Provisional Patent Application No. 62 / 231,723 incorporated by reference. . The bag can be formed from a portion of suitable material (eg, a band of material can be folded, sealed and cut to form the bag). A portion 150 of a web of material is schematically shown in FIG. 2, in which the lines shown in fig. 2 illustrate the locations and / or boundaries of certain features in the band portion. These lines may or may not actually be formed on the band portion 150 (for example, the lines representing the location of the pleats or the boundary of a sealing area may be included in Fig. 2 only to illustrate these features, but may not exist in the web portion, but other lines, such as a fill line, may be printed or otherwise formed in the web portion 150). In one embodiment, the band portion 150 may have a central pleat 153 and two outer pleats 155 that form the reinforced lower part 9 of the bag 3. When the reinforced lower part 9 of the bag 3 is formed, the band 150 is folded along the center fold 153 and the outer folds 155, so that the center fold is arranged between the outer sides of the bag 3. Consequently, the center fold 153 and the two outer folds 155 form four layers of overlapping material on the bottom of the bag, so that the bottom of the bag can be expanded to move from the non-upright position of container 1 (figs. 4 and 6) to the upright position (figs. 5 and 7 ) and / or to accommodate various sizes of products that will be contained in the bag. The upper limits of the lower reinforcement 9 are represented by lines 157 in FIG. 2. The bottom gusset 9 could be shaped, arranged, positioned and / or otherwise configured without departing from the disclosure.

As shown in fig. 2, the band portion 150 may include two sealing areas 119 that extend along the edge margins of the band portion. The limits of the sealing areas can be represented by respective lines 159. As shown in fig. 3, after the band portion 150 is folded and the reinforced bottom 9 is formed, the sealing areas 119 can be heat sealed to form respective heat sealed sides 19 that extend along the sides of the bag 3 in the lower reinforcement 9 of the bag. Consequently, the side portions of the overlapping layers of material are sealed along the edge margins and at the bottom of the bag. In the flat configuration of bag 3 (eg FIG. 3), the outer pleats 155 form the lowermost edge of the bag. Optionally, fill lines 158 (FIG. 2) may be printed or otherwise formed on the sides of the band portion 150 to indicate a recommended stopping point for a product (eg, water) that could be poured into the bag. 3. The band portion 150 and / or the bag 3 could be shaped, arranged and / or otherwise configured without departing from the disclosure.

In one embodiment, the reinforced container 1 may be formed by a packaging system that fixes the web of material to form the bags 3 to respective preforms 10, and the preforms and the web are moved through a respective packaging system. and are transformed into individual packages by various portions and components of the system. In another embodiment, the reinforced container 1 may be formed by systems and procedures similar to those shown in US Provisional Patent Application No. 62 / 231,723, incorporated by reference, in which The bags 3 can be at least partially formed and then attached to the respective preforms 10, and the preforms and web can be moved through a respective packaging system and transformed into the individual packages by various portions and components of the system. The reinforced package 1 could be formed otherwise without departing from the disclosure.

In one embodiment, the material for forming the bags 3 can include pre-printed paper, polyethylene, or other material that includes flexible and heat-sealable materials. The sealed side portions 19 of each bag 3 are formed by joining (for example, by heat sealing, such as a rotary heat sealer) the overlapping edge margins 119 of the material web 150. The bags 3 can be attached to the respective preforms 10 by means of glue. For example, the bag 3 can be attached to the front panel 21 of the preform 3 in glue strips G1. Bag 3 could be formed and / or otherwise attached to preform 10 without departing from the disclosure.

In one embodiment, the individual preforms 10 with the bags 3 attached are transported in the system to a folder / gluer carton forming assembly that includes a series of folders that position the various tabs and panels of the preform 10 to form the flat cardboard boxes 5 that can be packaged and shipped to be filled with the product. In one embodiment, the preform 10 can be folded along the lateral fold lines 26, 27, so that the panel portions 28b, 29a overlap, at least partially, with the respective panel portions 28a, 29b and the second rear panel 25 overlaps the first rear panel 23 and is adhesively attached thereto. As shown in figs. 1 and 3, panels The backs 23, 25 may include glue strips G1, so that they stick to the bag 3 when folded over the bag. In the illustrated embodiment, the first lower end flange 45 overlaps with the second lower end flange 42 and is adhesively attached thereto (eg, with a glue strip G2, Figs. 1 and 3). to form the closed bottom 20 of the carton (Figs. 6 and 7).

As shown in figs. 4 and 6, in the flat configuration or in the non-upright position of the container 1, the carton 5 folds flat by folding the side panels 28, 29 along the fold lines 26, 27, so that the panel portions 28a, 28b overlap each other and panel portions 29a, 29b overlap each other. Additionally, the bottom 20 of the carton 5 folds outward at the fold lines 49, 43, 47. In an alternative embodiment, the bottom 20 could be configured to fold inward when the carton it is in the non-upright position. The container 1 can be placed in the upright configuration shown in FIGS. 5 and 7 by grasping the sides 28, 29 and pushing the sides inward at the fold lines 26, 27 in the direction of the arrows A1 (fig. 6), causing the front panel 21 and rear panel 23 to separate or they move away from each other to give the package its three-dimensional shape and form the interior space 17 of the bag 3 to contain a product. As the panels 21,23 are pulled apart, the bottom 20 can be folded along the fold lines 43, 47, 49 so that the bottom panel 41 and the bottom tabs 42, 45 extend through from the bottom of the carton from the front panel 21 to the rear panel 23. Since the bag 3 attaches to the front and rear panels 21, 23, the sides of the bag 3 can be moved apart as the front and back panels are separated from each other. Consequently, the reinforced bottom portion 9 of the bag can be expanded to extend through the bottom of the package 1, supported by the bottom portion 20 of the carton. In one embodiment, since the bottom panel 41 and the bottom tabs 42, 45 are folded to extend through the bottom of the carton, the brackets 71, 75 can be detached from the bottom panel 41 and the tab. respective bottom 45 along the respective cuts 73, 77, so that the supports continue to extend and are coplanar with respect to the respective front panel 21 and rear panel 23. Brackets 71, 75 may form respective openings 79 in respective bottom panel 41 and bottom end flange 45 (FIG. 7). The container 1 could otherwise be moved between the upright position and the folded position without departing from the disclosure.

In the upright configuration of container 1 (Figs. 5 and 7), the supports 55, 65, 71, 75 extend downwardly from the respective side panels 28, 29, the front panel 21 and the rear panel 23 to form the portion lowermost part of the lower part 20 of the carton 5. Consequently, the container 1 can be supported on a flat surface on the supports 55, 65, 72, 75 and placed in an upright position in the upright configuration to allow access into the interior space 17 through the upper part 7 of the bag 3. As shown in figs. 5-7, recesses 81 may be formed on each side of the brackets 71,75, such that a recess 81 extends between each of the brackets 71, 75 and a respective one of the brackets 55, 65. In a mode of In embodiment, each of the recesses 81 is defined by an edge of one of the supports 71, 75, one of the fold lines 43, 47 and an edge of one of the supports 55, 65. Similarly, a recess 83 It may extend between the supports 55 and between the supports 65, such that each of the recesses 83 is defined by the respective edges of the supports 55 or 65 and the respective oblique edges 57, 67.

In one embodiment, the sealed bottom portion 9 of the bag 3 may be a watertight seal that allows the user to add water or milk to the interior 17 of the bag of the reinforced package 1 to combine it with a food product (for example, cereal, oatmeal, etc.) inside. The package 1 can be placed in a microwave oven to heat the food product without departing from the disclosure. Furthermore, the package 1 can be used to contain other types of food products without departing from the disclosure.

The fold lines 51, 26 on the side panel 28 and the fold lines 53, 27 on the side panel 29 increase the rigidity of the formed container 1. Side panels 28, 29 can be folded along fold lines 51, 26; 53, 27 to slope inwardly to reinforce the structure of the carton 5, so as to entice the package 1 to remain in the upright configuration once formed. The package 1, the carton 5 and / or the preform 10 could have other characteristics, or could be shaped, arranged and / or otherwise configured without departing from the disclosure.

In general, as described herein, liners or bags can be formed from a paper stock material, although various plastic or other liner materials can also be used, and can be lined or coated with a desired material. The reinforcing constructions, preforms, and / or sleeves described herein can be made from a more rigid material, such as clay-coated natural kraft ("CCNK") paper. Other materials such as cardboard, paper, plastic, or other synthetic or natural materials can also be used to form the components of the packages described herein.

In general, the preforms of the present disclosure can be constructed from cardboard having a gauge such that it is heavier and stiffer than plain paper. The blank can also be constructed of other materials, such as card stock or any other material that has suitable properties to allow the carton to function, at least in general, as described above. The preform can be coated, for example, with a clay coating. Products, advertising and other information or images can be printed on the clay lining. The preforms can then be coated with a varnish to protect the information printed on the preforms. The preforms can also be coated with, for example, a protective layer against moisture, on one or both sides of the preforms. The preforms can also be laminated or coated with one or more sheet-like materials on selected panels or panel sections.

As an example, a tear line may include: a slit that extends partially into the material along the desired line of weakness and / or a series of separate slits that extend partially and / or completely through the material along the along the desired line of weakness, or various combinations of these characteristics. As a more specific example, one type of tear line is in the form of a series of separate grooves that extend completely through the material, with contiguous grooves slightly spaced so that a notch (e.g., a small portion of the material similar to a bridge) is defined between adjoining grooves to typically temporarily connect the material across the tear line. The notches are broken during the tear along the tear line. Typically, the notches are a relatively small percentage of the tear line and, alternatively, the notches can be omitted or torn on a tear line so that the tear line is a continuous cut line. That is, it is within the scope of the present disclosure for each of the tear lines to be replaced with a continuous slit or the like. For example, a cut line can be a continuous slit or it could be wider than a slit without departing from the present disclosure.

According to exemplary embodiments, a fold line can be any substantially linear, though not necessarily straight, form of weakness that facilitates folding along the line. More specifically, but not for the purpose of reducing the scope of the present disclosure, fold lines include: a score line, such as lines formed with a blunt scoring knife, or the like, that creates a pitted or recessed portion in the material along the desired line of weakness; a cut that extends partially into a material along the desired line of weakness and / or a series of cuts that extend partially toward and / or completely through the material along the desired line of weakness; and various combinations of these characteristics. Typically, in situations where a cut is used to create a fold line, the cut will not be too extensive in a way that may cause a sensible user to incorrectly consider the fold line to be a tear line.

The above embodiments can be described as having one or more panels glued together during erection of the carton embodiments. The term "glue" is intended to encompass all types of adhesives commonly used to secure cardboard box panels in place.
