Definitions

  • the present invention relates to the field of container closures, and more particularly, to a closure for a liquids container which provides for selective release of the contents of such container.
  • One class of closure comprises a one piece construction, with a main cover member that can be secured to the outer periphery of a beverage cup in a conventional manner, and which has a cut-away flap portion that can be selectively displaced between a closed position, whereat the flap is positioned substantially in line with the main cover member, and an open position, whereat the flap projects away from the main cover member, thereby to provide an opening for flow of the liquid contents of the beverage cup.
  • United States Patent No. 4,741, 450 (Braude), issued May 3,1988 and United States Patent No. 5,799, 814 (Schaefer et al.), issued September 1,1998 are both exemplary of this class, which is known to be capable of manufacture at relatively low cost, but can provide an unreliable liquid seal.
  • Another class of closure comprises two sections joined at their center.
  • the outer section can be secured to the outer periphery of a beverage cup in a conventional manner, and forms an annular well which has a plurality of openings therein.
  • the inner section is stressed such that it normally bears against the openings, thereby to provide a liquid seal between said openings and any contents of the container.
  • the center of the outer section is depressed, the inner section separates from the openings, thereby to permit fluid contents of the container to flow through the openings.
  • United States Patent No. 3,797, 696 (Debrell), issued March 19,1974 ; United States Patent No. 3,727, 808 (Fitzergerald), issued April 17,1973 ; and United States Patent No. 3,730, 399 (Dibrell et al.), issued May 1,1973, are all exemplary of this latter class, which is known to be capable of providing a relatively liquid-tight seal, but suffers from the need for users to maintain pressure on the centre portion to permit fluid flow, which can be inconvenient.
  • the present invention comprises a closure for a container having an aperture bounded by a rim.
  • the closure comprises a substantially bowl-shaped body having an interior surface and an exterior surface and having defined therethrough a passage.
  • the closure further comprises a connection means for sealing the body to the container such that the interior surface in combination with the container defines an interior space into which the aperture opens during use of the closure.
  • the body is selectively deformable, upon manual manipulation, between an open configuration, wherein the passage is in fluid communication with the aperture, and a closed configuration, wherein one of the interior surface and the exterior surface is sealed against the passage.
  • the present invention comprises a closure for a container having an open top bounded by a rim.
  • the closure comprises a closure body having a lower surface, an upper surface, and a substantially planar portion.
  • the closure further comprises: connection means for sealingly connecting said closure body to said container; a hollow protrusion formed in said closure body and projecting upwardly above said planar portion; and a folding lip portion formed on an outwardly facing side of said protrusion and having a hole formed therein.
  • the lip portion is selectively deformable, upon manual manipulation, between an open configuration wherein said hole is open for flow of fluid therethrough, and a closed configuration, wherein said hole is sealed shut by surrounding sections of the lip portion.
  • FIGURE 1 a preferred embodiment of the closure of the present invention is illustrated and designated with general reference numeral 20.
  • the closure 20 is for a container 22 having an aperture or open top bounded by a rim 26, such as a disposable coffee cup.
  • a rim 26 such as a disposable coffee cup.
  • the container 22 does not form part of the invention.
  • the closure 20 comprises a substantially bowl-shaped body 28.
  • the body 28 has an interior surface 30, best seen in FIGURE 4, and an exterior surface 32 and has defined therethrough a passage or aperture 34, as illustrated in FIGURE 2 and FIGURE 7.
  • the closure 20 further comprises connection means for sealing the body 28 to the container 22 such that the interior surface 30 of the body 28, in combination with the container 22, defines an interior space 38 into which the aperture opens, as indicated in FIGURE 10.
  • connection means is designated with general reference numeral 36 in FIGURE 1, and comprises a skirt 60 which extends peripherally around and is operatively connected to the body 28, the skirt 60 having a peripherally extending groove 70 therein, as indicated in FIGURE 4, shaped and dimensioned to frictionally, sealingly, releasably receive the rim 26.
  • the body 28 When so sealed to the container 22, the body 28 may be selectively deformed, by manual manipulation, between a closed configuration, as illustrated in FIGURE 1, wherein the interior surface 30 is sealed against the aperture 34 to resist fluid flow, and an open configuration, as illustrated in FIGURE 10, wherein the passage or aperture 34 is in fluid communication with the interior space, to permit fluid flow.
  • a pair of vent holes 58 are formed in the body 28 (actually, in an annular sheath part44 of the body 28, described more fully in the following paragraph) on circumferentially opposite sides of the passage 34 to facilitate fluid egress, and avoid vacuum lock.
  • the structure of the body 28 will now be described in more detail with reference to FIGURES 6 and 7, and will be seen to comprise a cap part 62; the aforementioned sheath part 44; an insert part 50; and an intermediate part 56.
  • the sheath part 44 which has the passage 34 formed therein, has a first end 46 and a second end 48 and is frustoconical, tapering in external dimension towards the second end 48, which is occluded by and rigidly connected to the cap part 62.
  • the insert part 50 also has a first end 52 and a second end54, the second end 54 being shaped and dimensioned to be received within the sheath part 44.
  • the intermediate part 56 extends between the first end 46 of the sheath part 44 and the second end 54 of the insert part 50, and flexibly connects same for relative movement, upon manual manipulation, from the open position, seen best in FIGURE 7, where the insert part 50 and the intermediate part 56 are disposed exteriorly relative to the sheath part 44, to the closed configuration, where the second end 54 of the insert part 50 (in fact, the entire insert part 50) is disposed, in substantially form-fitting, nested relation, within the intermediate part 56, and the intermediate part 56 is disposed, in substantially form-fitting, nested relation, within the sheath part 44, as indicated in FIGURE 6. (It will be evident that during manual manipulation from the open configuration to the closed configuration, the intermediate part 56 collapses into the sheath part 44 and the second end 54 of the insert part 50 collapses into the intermediate part 56.)
  • the interior surface 30 is formed with a protuberance 42 which projects through the passage 34 in a sealing manner when the body 28 is in the closed configuration, as indicated in FIGURE 1 and FIGURE 6.
  • the cap 62 forms an interiorly disposed protuberance having an outwardly tapering frustoconical sidewall 78 which, when the body 28 is in the closed configuration, sealingly engages against the junction of the intermediate part 56 and the insert part 50, so as to yet further increase the effectiveness of the seal.
  • the open configuration is a static open configuration wherein the body 28 is stable without an external application of force
  • the closed configuration is a static closed configuration wherein the body 28 is stable without an external application of force
  • the body 28 is constructed of a resilient plastic and is of the "overcentre" variety, which is unstable at locations intermediate the open and closed position, and thus, self- biasing into one of the open and closed configuration, depending upon the relative locations of the various parts.
  • a tubular pedestal part 74 is provided which rigidly extends between and connecting the first end 52 of the insert part 50 to the skirt 60, and the first end 52 of the insert part 50 is constructed of smaller external dimension than the first end 46 of the sheath part 44, thereby to define, in the closed configuration, an overhanging lip designated with general reference number 76 in FIGURE 6, which can be pried upwardly by the fingers of a user.
  • the closure 20 may be constructed from the structure 68 illustrated in FIGURE 8 wherein each of the sheath part 44; intermediate part 56; and insert part 50 take the form of a substantially frustoconical annulus connected to one another (preferably, formed integrally) in alternating orientation.
  • the intermediate part 56 is collapsed into the sheath part 44 and the insert part 50 collapsed into the intermediate part 56, and thereafter, the sheath part 44 is affixed, by sonic welding, adhesive or the like, to the insert part 50 at the side opposite to that in which the passage 34 is formed, so as to arrive at the preferred embodiment illustrated in FIGURE 9 (and FIGURE 1).
  • FIGs 11 to 13 illustrate another embodiment of a closure suitable for use on a coffee cup, for example.
  • This closure 82 is similar to the closure illustrated in Figures 8 and 9 of the drawings, except for the differences noted hereinafter.
  • the closure 82 is shown mounted on the annular rim of a coffee cup 84.
  • the closure 82 has an annular connection means as well for sealing its body to the cup, this connection means including a skirt 60 which is integrally connected to the body 84 of the closure.
  • the skirt forms an annular groove 70 which is shaped and dimensioned to frictionally and sealingly receive the rim of the cup.
  • a primary difference between the embodiment of Figures 11 to 13 and that of Figures 8 and 9 is the height of its tubular, pedestal part 88 which is substantially greater than the above described pedestal part 74.
  • the height of the pedestal part 88 is in the range of 1 cm to 2 cm and it is most preferably close to 1 cm. Because of the greater height of the pedestal part 88, it can be easier for the user of this closure to manipulate the closure from the closed position illustrated in Figure 12 to the open position. It will be seen that in the closed position shown in Figure 12, the closure has an overhanging lip 76 which is spaced a substantial distance above an upper rim 90 of the closure.
  • closure 82 is also provided with an insert part 50 visible in Figure 11 and the upper end of this part is integrally connected to an outwardly sloping intermediate part 56.
  • the passage 34 of this closure is also formed in the sheath part 44.
  • FIG. 14 to 17 This closure is indicated generally at 92. Again, it will be understood that this embodiment is constructed generally in accordance with the embodiment of Figures 8 and 9 described above, except for the differences noted hereinafter.
  • Figure 15 illustrates the closure 92 mounted on a cup 94 which can, for example, be a standard coffee cup.
  • This closure is also fitted with means for connecting the body 96 of the closure to the cup, these means including the skirt 60 which extends peripherally around the bottom of the closure and which forms a groove to frictionally and sealingly receive the rim of the cup.
  • the closure 92 includes an upper cap part 98, a downwardly sloping sheath part 100, an insert part 102 visible clearly in Figure 16, and an intermediate part 104.
  • the sheath part 100 has a passage or hole 106 formed therein.
  • a protuberance 108 is Formed on the intermediate part 104 which of course projects through the hole 106 when the body of the closure is in the closed position.
  • this embodiment has an outwardly projecting, annular lip 110 which makes the closure easy to manipulate in order to move the closure from the fully closed position to the intermediate, open position of Figure 15.
  • the lip 110 projects beyond the skirt 60 a short distance making it relatively easy for the user's thumb or finger to push the projecting lip upwardly in order to move the closure to the open position.
  • tubular pedestal part 110 it is not necessary for the tubular pedestal part 110 to be as high as in the embodiment of Figures 11 and 12. In fact, this pedestal part 110 can be constructed with the same height as the embodiments of Figures 1 to 9.
  • Figure 16 illustrates the preferred angle of slope of the insert part 102.
  • the slope of the insert part 102 is approximately thirty degrees to the horizontal plane (assuming that the bottom of the closure is horizontal).
  • the preferred slope of the intermediate part 104 is also about thirty degrees to the horizontal either in the closed position or in the fully opened position illustrated in Figure 16.
  • closure 115 is indicated generally at 115.
  • This closure has a primarily flat body 116 except for a relatively large, upwardly projecting protrusion 118.
  • the closure 115 has means for connecting the body 116 to a container such as the container illustrated in Figure 10 and this connection means includes a skirt 60 which extends around the circumference of the body. As in the previous embodiments, this skirt forms a peripherally extending groove 70 which is shaped to frictionally and sealingly receive the cup rim.
  • the aforementioned protrusion 118 can have a generally triangular shape in plan view as shown in Figure 19 with a rounded inner end at 120. This inner end can be located close to the centre 122 of the closure.
  • the top surface 124 of the protrusion is rounded, forming a convex curve extending from one side 126 to an opposite side 128.
  • a folding lip 132 integrally attached to the protrusion is a folding lip 132.
  • This lip extends about the upper perimeter of a semi-circular front wall 134 which effectively closes the front side of the protrusion.
  • a small hole 136 Formed in the upper extremity of the lip is a small hole 136 which, in the case of a coffee cup lid, can be a drinking hole.
  • the protrusion is formed with an intermediate wall section 140 and the folding lip 132 is integrally connected to a front edge 142 of this wall section.
  • the folding lip 132 includes a rear wall section 144 and a forward wall section 146 which are connected together along a fold line 148.
  • the hole 136 is located along the fold line 148 and it extends only a short distance into the two wall sections 144, 146.
  • FIGs 22 to 24 illustrate yet another embodiment of a closure constructed in accordance with the invention, this embodiment being particularly suitable for use on a larger container such as paint can 152.
  • the closure of this embodiment is designated generally by reference 154.
  • the illustrated paint can can be per se of known construction except for the construction of the illustrated closure.

  • the can 152 is equipped with external connecting threads located at its top end 156. The threads themselves cannot be seen in Figure 22 as they are covered by the bottom portion of the closure 154. In any event, these threads are standard construction and they permit a threaded closure or top for the paint can to be detachably connected to the can in an efficient, saleable manner.
  • closure 154 can be constructed in a manner similar to the closure illustrated in Figures 8 and 9 and described above.
  • a primary difference of the closure 154 is that it is fitted with an internally threaded skirt at 156 that forms the bottom portion of the closure.
  • the internal threads (not shown) are dimensioned and arranged to cooperate smoothly with the external threads formed on the top portion of the paint can.
  • a preferred optional feature of this closure is that it is fitted with a skirt extension 158.
  • the skirt extension may be formed with a rippled or corrugated outwardly facing wall that permits it to be easily gripped for turning purposes.
  • the skirt extension extends radially beyond the annular lip 160 formed by the body 162 of the closure. In this way, the skirt extension is made easier to grip so that the closure can be readily turned about its vertical central axis.
  • the closure 154 is constructed for a larger container such as a paint can, it will be understood that it is made of a thicker, stronger plastic sheet material. Suitable plastics that can be used include polypropylene and polyethylene. It will be understood that the plastic sheet material must be selected so that it has sufficient strength and rigidity to properly contain the paint within the can for all normal conditions of use.
  • closure 154 Additional features of the closure 154 that can be seen in the figures include a circular top or cap part 164, a downwardly sloping sheath part 166 and an intermediate part 168.
  • a suitable hole 170 is formed in one side of the sheath part. In the closed position shown in Figure 22, this hole can be sealed shut by means of a protuberance 172, this protuberance being formed on the intermediate part 168.
  • Air holes 174 can be formed on opposite sides of the sheath part 166, if desired or necessary. If desired, protuberances can be provided on the intermediate part 168 to close sealingly the air holes 174 in the closed configuration.
  • Figure 23 illustrates the closure 154 in an intermediate open position which allows paint (or any other liquid in the container) to flow out through the hole 170.
  • the closure has been pried upwardly on one side only, that is on the side of the hole 170.
  • the upper portion of the closure can be fully raised to the position illustrated in Figure 24. Movement of the closure to this position may be desirable, for example, for cleaning the lid. Particularly for a paint can lid, it can be important to clean off the interior of the lid so that it will function properly for future use purposes.
  • connection means for sealing the body to the container in the preferred embodiment comprise a groove to receive the rim of the container
  • the body and the container may, for example, be formed integrally, in which case the connection means will constitute a physical connection between the body and the container, and the rim will be a notional structure.
  • the invention is not limited to beverage containers and paint cans, but may be utilized with equal utility in combination with other larger containers.
  • the closure of the preferred embodiment is annular, and relatively "affixed" at one side the body may take other shapes, for example, rectangular, akin to an accordion, or polygonal, and may "open" from all sides.
  • the structure illustrated in the preferred embodiment contemplates its construction from a precursor structure, it will be evident that such precursor structure is not necessary.
  • sealing of the passage is effected by the interior surface, it is possible to seal the passage by the exterior surface, for example, by provision of an externally-projecting protuberance on the insert part, and by locating the passage through the intermediate part of the body.
