Definitions
- the present invention relates to thermoplastic containers and lids, and more particularly to a device for stacking thermoplastic containers and/or lids.
- Containers for the storage of items are well known. Such containers are used to store a variety of articles, from food to general household items including everything from craft supplies to children's toys. Generally, such containers can be characterized by shape and size. Containers that do not include a lid require a separate sealing member, such as a plastic wrap or aluminum foil. Often, the plastic wrap or aluminum foil is loose or jostled during movement of the container, and hence, the container is usually not properly sealed or closed to prevent contents therein from spilling. Containers that include lids overcome this problem.
- container lids As is well known, many different types and sizes of container lids exist. When such container lids are placed together in a confined space, such as a cupboard, cabinet, drawer, shelf, refrigerator, or the like, a disorganized condition can develop, preventing a user from easily locating a container lid of a particular size and shape. Further, as a user is attempting to locate a particular container lid, other items may be jostled, thereby causing a container lid or one or more of the items to fall off a supporting surface to the floor, resulting in breakage of the items and/or spilling of contents and/or lost container lids. Still further, when container lids are stacked on top of each other in an unconfined location, the container lids tend to slide out of the stacked configuration and into a disorganized state making it difficult to locate the proper size and/or shaped container lid.
- Bross U.S. Pat. No. 4,632,472 discloses a slidable drawer system mounted below a shelf. Guide rails are mounted to the shelf and receive flanges of the drawer, wherein the drawer slides in and out of the guide rails. A finger is attached to each guide rail wherein the fingers contact the rear wall of the drawer to prevent removal of the drawer from the guide rails in a first direction. To completely disengage the drawer from the guide rails the fingers must be pushed upwardly away from the rear wall to disengage the drawer from the guide rails.
- a front portion of the drawer includes extending side walls that contact the guide rails as the drawer is being pushed inwardly, thus preventing the drawer from sliding out of the housing in a second direction.
- Marino Jr. U.S. Pat. No. 5,964,359 discloses a modular storage system for multiple containers including a base having a top wall, a side wall, and a bottom wall wherein the bottom wall has a front opening cutout.

Description
- This application is based on and claims priority from provisional patent Application No. 60/429,687 filed on Nov. 27, 2002.
- The present invention relates to thermoplastic containers and lids, and more particularly to a device for stacking thermoplastic containers and/or lids.
- The use of containers for the storage of items is well known. Such containers are used to store a variety of articles, from food to general household items including everything from craft supplies to children's toys. Generally, such containers can be characterized by shape and size. Containers that do not include a lid require a separate sealing member, such as a plastic wrap or aluminum foil. Often, the plastic wrap or aluminum foil is loose or jostled during movement of the container, and hence, the container is usually not properly sealed or closed to prevent contents therein from spilling. Containers that include lids overcome this problem.
- As is well known, many different types and sizes of container lids exist. When such container lids are placed together in a confined space, such as a cupboard, cabinet, drawer, shelf, refrigerator, or the like, a disorganized condition can develop, preventing a user from easily locating a container lid of a particular size and shape. Further, as a user is attempting to locate a particular container lid, other items may be jostled, thereby causing a container lid or one or more of the items to fall off a supporting surface to the floor, resulting in breakage of the items and/or spilling of contents and/or lost container lids. Still further, when container lids are stacked on top of each other in an unconfined location, the container lids tend to slide out of the stacked configuration and into a disorganized state making it difficult to locate the proper size and/or shaped container lid.
- Carroll, U.S. Pat. No. 4,241,668 discloses a frame for mounting a container and a cover below a supply shelf. The frame is suspended from spaced apart rails depending from the supply shelf by multiple hooks. The frame includes side beams with inwardly extending flanges for engaging the container and cover and allowing the container and lid to inserted and removed from the frame.
- Bross U.S. Pat. No. 4,632,472 discloses a slidable drawer system mounted below a shelf. Guide rails are mounted to the shelf and receive flanges of the drawer, wherein the drawer slides in and out of the guide rails. A finger is attached to each guide rail wherein the fingers contact the rear wall of the drawer to prevent removal of the drawer from the guide rails in a first direction. To completely disengage the drawer from the guide rails the fingers must be pushed upwardly away from the rear wall to disengage the drawer from the guide rails. A front portion of the drawer includes extending side walls that contact the guide rails as the drawer is being pushed inwardly, thus preventing the drawer from sliding out of the housing in a second direction.
- DeBruyn U.S. Pat. No. 4,653,818 discloses a dry food storage container system wherein containers are supported by hanger plates that form a rack and are adapted to slide in and out of a cabinet. An upwardly projecting lug formed on the hanger plate restricts free sliding movement of the container. The containers may be laterally removed from or laterally inserted into the hanger plates when the container is lifted slightly over the lugs.
- Marino Jr. U.S. Pat. No. 5,964,359 discloses a modular storage system for multiple containers including a base having a top wall, a side wall, and a bottom wall wherein the bottom wall has a front opening cutout. A jar with cover may be inserted into the opening wherein the cover rests on the bottom wall and suspends the jar with contents therefrom.
- Semon et al. U.S. Pat. No. 6,056,378 discloses an add-on drawer and a method of mounting the same to a horizontal surface. The drawer includes a tray for storing items and at least two rails for slidably supporting the drawer. Each rail includes stops to prevent removal of the drawer from below the horizontal surface.
- Dimes U.S. Pat. No. 371,044 discloses a plate rack. The rack holds plates in a vertical position. The rack utilizes base supports and wire bent to the curve of the plate to support the plate in the vertical position.
- Moore U.S. Pat. No. 1,349,084 discloses a kettle cover drainer. The device acts as a stand utilizing bent wires to hold a kettle cover in a vertical position in order for the cover to drain of any liquid. The wires are held in a vertical orientation by attachment to a base that has a drain for funneling runoff from the kettle cover.
- Hay U.S. Pat. No. 1,994,195 discloses a rack for drying or storing dishes. The rack utilizes a horizontal wire frame having a length much greater than its width along with vertical wires in contract with the horizontal wires. Dishes are then placed in the rack in a vertical position and held there by the vertical wires.
- Greensfelder U.S. Pat. No. 2,600,755 discloses a wire cover rack. The rack rests on a horizontal surface and utilizes a series of interconnected wires to support the covers. The rack comprises a base section of parallel wires and a back section of parallel wire to support the covers. The base section is raised by a support at one end so it is not parallel with the surface and the back section is angled away from vertical and toward the base. Thus, when covers are inserted vertically they contact both sections and are held in the vertical position.
- Swan U.S. Pat. No. 4,396,123 discloses a tape cassette holding bracket. The holding bracket is a generally L-shaped member with a plurality of slots for holding cassettes. The slots further include flanges that extend into the slots that hold the cassette in place at the wider portion of the cassette.
- Vaughn U.S. Pat. No. 5,660,284 discloses a storage rack for container lids. The rack is capable of storing lids in either a horizontal or vertical position.

- Referring now to FIGS.1-3, a first embodiment of a stacking
device 40 includes a semicircular plate-shapedmain member 42 and at least one upwardly directed support member 44. Preferably, (although not necessarily) five support members 44 a-44 e extend transversely with respect to themain member 42 and are integral therewith. At least one support member 44, preferably (again not necessarily) thesupport member 44 c, includes a curvedmain portion 46 that conforms to and abuts anouter periphery 48 of themain member 42. At least one inwardly directedwall member 50, and preferably sixwall members 50 a-50 f, are integral with and extend transversely from the support members 44 in a direction substantially parallel to themain member 42. Each of thewall members 50 a-50 f is c-shaped and includes opposed ends 52 a, 54 a through 52 f, 54 f, respectively. - A first plurality or set of openings56 is defined between the
support members wall members 50 a-50 f. In the embodiment illustrated in FIGS. 1-9, six openings 56 a-56 f are defined, although a different number could alternatively be defined by a like number ofwall members 50. As seen specifically in FIG. 3, the first openings 56 a-56 f preferably all have the same width W1 defined by a chord representing the shortest distance between opposed portions 58 a-58 f, 60 a-60 f of the support members 44. Preferably, the width W1 is slightly smaller than the overall diameter of acircular container lid 70. As noted in greater detail hereinafter, the width W1 may also be slightly smaller than the diameter of a peripheral rim of acontainer 71. (seen in FIGS. 4-7). Inner peripheries 72 of thewall members 50 define a second plurality or set ofopenings 74 a-74 f each having a width W2 that is also somewhat smaller than the overall diameter of thecontainer lid 70. Further, each width W2 may be (although not need be) smaller than the width W1 of each first opening 56. - Referring now to FIGS.4-7 a number of cavities 76 a-76 e each capable of receiving a
circular container lid 70 or a peripheral rim of acontainer 71 is formed between the support members 44 and thewall members 50 a-50 f and at least onecavity 76 f is formed between themain member 42, the support members 44 and thewall member 50 f. A different number of cavities 76 may be formed by a different number ofwall members 50, as should be evident. - Referring now to FIG. 8, the
main member 42 of the stackingdevice 40 may be secured to a cabinet orsurface 82 by any suitable means, such as fasteners 84 a-84 c that extend through mountingholes 86 a-86 c in themain member 42 into the cabinet orsurface 82. Alternatively, if desired, double-sided tape, an adhesive, a hook and loop fastener (i.e., Velcro), or other device may be disposed between themain member 42 and the cabinet orsurface 82 to secure the stackingdevice 40 thereto. - Once the stacking
device 40 is mounted as seen in FIG. 8, a user may insert thecircular container lid 70 into one of the cavities 76. Once the user aligns the lid with one of the openings 56, the user applies an insertion force to thecircular container lid 70 in a first direction into the respective opening 56. Thecontainer lid 70 contacts a respective pair of portions 58, 60 (for example, theportions container lid 70. The portions 58, 60 are relatively stiff and capable of flexing a rim of thelid 70 and/or the body of the lid 70 a sufficient degree to allow thecontainer lid 70 to enter the respective cavity 76. Alternatively, the portions 58, 60 may flex to a degree sufficient to allow thelid 70 to enter the cavity 76. In either event, thelid 70 thereafter returns substantially to the undeformed state (or alternatively remains in a flexed condition in contact with the portions 58, 60) to create a first interference fit. Moreover, a second interference fit is established with thewall members 50. The first interference fit prevents thecontainer lid 70 from being removed from the stackingdevice 40 through the first openings 56 until a sufficient removal force is exerted to overcome the resistance force exerted by the end portions 58, 60. The second interference fit prevents thecontainer lid 70 of acontainer 70 from moving downwardly out of the suspension device through thesecond openings 74. - As should be evident from the foregoing, up to six lids may be stored in the
device 40, although a different number of lids could be accommodated depending upon the number ofwall members 50 that are provided in thedevice 40. Also, themain member 42 could be omitted, if desired, in which case one of theouter wall members 50 may be secured by fasteners or other securing means to the cabinet orsurface 82. Still further, thedevice 40 need not be secured to a surface at all; rather, thedevice 40 may simply be placed on a surface and/or in a cabinet, a drawer, a pantry, a refrigerator or other enclosed space. Still further, the stackingdevice 40 can optionally be integrally formed with a shelf, such as arefrigerator shelf 88 as seen in FIG. 9. - As seen in FIGS. 6 and 7, a peripheral rim of a
container 71 such as a jar or a thermoplastic disposable container (as seen in FIGS. 4-7) can alternatively or in addition be inserted into one of the cavities 76. This insertion is accomplished in the same manner as described above in connection with FIGS. 4 and 5. This permits the container 71 (with or without a lid mounted thereon) to be supported by thedevice 40. - In any of the embodiments described herein, the lid(s)70 and/or
containers 71 may be inserted into the cavities 76 with thedevice 40 oriented as seen in FIG. 1 (i.e., with themain member 42 down, in which case the arrangement seen in FIG. 5 or 7 results) or may be inserted with the device in the orientation seen in FIG. 2 (i.e., with themain member 42 up, thereby resulting in an arrangement similar to FIGS. 13 and 14 described hereinafter). - The remaining FIGS. illustrate other embodiments of the present invention. Referring now to FIGS. 10 and 11, a second embodiment of a stacking
device 90 includes a semi circular plate-shapedmain member 92 and asupport member 94 extending transversely with respect to themain member 92. Thesupport member 94 includes a plurality of outwardly flaredresilient end portions 100 on afirst side 101 of the stackingdevice 90, and endportions 102 on asecond side 103 of the stackingdevice 90. In the illustrated embodiment, twelveend portions 100 a-100 f, 102 a-102 f are provided on eachside device 90. A number of spaced, inwardly directedwall members 108 are further provided in alignment with theend portions support member 94 and extend transversely therefrom in a direction substantially parallel to themain member 92. - Each
end portion 100 a-100 f is associated with anopposed end portion 102 a-102 f, respectively, to define a first set of openings 110 a-110 f, respectively. As seen in FIG. 12, the first set of openings 110 a-110 f all have a width W1 wherein a chord defined by the shortest distance between the flaredresilient end portions circular container lid 112 or peripheral rim of a container 114 (FIGS. 13-16). Inner peripheries 116 of thewall members 108 define a plurality of second openings 118 each having a width W2 that is smaller than the width W1 of the first openings 110. Preferably, inner peripheries 116 a-116 f of thewall members 108 a-108 f define six second openings 116 a-116 f for receiving thecircular container lids 112 or the peripheral rim of acontainer 114. (FIGS. 13-16) - Referring now to FIGS.13-16, and similar to the previous embodiment, five cavities 117 a-117 e are formed between the
support member 94 andwall members 108 a-108 f and onecavity 117 f formed between themain member 92, thesupport member 94 and thewall member 108 a. Each cavity 117 is capable of receiving thecircular container lid 112 or the peripheral rim of acircular container 114. - As in the previous embodiment, the
main member 92 of the stackingdevice 90 may be secured to a cabinet orsurface 82 by any suitable means or thedevice 90 may be left free as noted above. A user inserts acircular container lid 112 or the peripheral rim of acontainer 114, such as ajar or a thermoplastic disposable container (as seen in FIGS. 13-16), into one of the first openings 110. As insertion force is applied thecontainer lid 112 or the peripheral rim of thecontainer 114 contacts the resiliently flaredend portions end portions end portions end portions container lid 112 or peripheral rim of thecontainer 114 from being removed from the stackingdevice 90 through the first openings 110 until a sufficient removal force is exerted to overcome the resistance force exerted by the resiliently flaredend portions container lids 112 or peripheral rim of acontainer 114 from moving downwardly out of the suspension device through the second openings 118. - As noted in the previous embodiment, the stacking
device 90 can optionally be integrally formed as part of ashelf 88. - A third embodiment of the present invention is shown in FIGS.17-22 and comprises a stacking
device 130. Referring now to FIG. 17, thedevice 130 includes a square-shaped platemain member 132 integral with asupport member 134 extending transversely with respect to themain member 132. Any number of inwardly directed wall members 136, preferably six wall members 136 a-136 f, are integral with thesupport member 134 and extend transversely therefrom substantially parallel to themain member 132. Preferably, the wall members 136 a-136 e form fiveopenings 138 b-138 f and themain member 132 andwall member 136 f form asixth opening 138 a. The wall members 136 a-136 f preferably (although not necessarily) includeinterference members 140 adjacent the openings 138 a-138 f that prevent a square-shaped container lid 142 (as seen in FIGS. 21 and 24) from slipping out of the stackingdevice 130. - Referring now to FIG. 18, five cavities141 a-141 e capable of receiving the
square container lids 142 or a peripheral rim of asquare container 143 are formed between thesupport member 134 and the wall members 136 a-136 f and at least onecavity 141 f is formed between themain member 132, thesupport member 134 and thewall member 136 f. Preferably, each cavity 141 is capable of receiving the peripheral rim of acontainer 143 and/or asquare container lid 142. - As in the previous embodiment, the
device 130 may be mounted to or integrally formed with a surface. - Referring now to FIGS.19-22 a square-shaped
container lid 142 and/or the peripheral rim of a square shapedcontainer 143 is (are) placed over theinterference members 140 and inserted into the stackingdevice 130 through one of the openings 138. Once past theinterference members 140, thecontainer lid 142 and/or peripheral rim of thecontainer 143 rests on the wall members 136. A first interference fit is thus defined in a first direction between the interference members 136 and the container lid 146 and/or the peripheral rim of thecontainer 143. The wall members 146 further form a second interference fit with the container lid 146 and/or the peripheral rim of thecontainer 143 in a second direction transverse to the first direction to prevent thesquare container lid 142 or the peripheral rim of thesquare container 143 from falling through one or more of openings 150 a-150 f defined by innerperipheral surfaces 151 a-151 f of the wall members 136 a-136 f, respectively. - A user lifts the
square container lid 142 or the peripheral rim ofcontainer 143 over theinterference members 140 to remove thecontainer lid 142 or thecontainer 143 from the stackingdevice 130. - All of the embodiments of the stacking device of the present invention are preferably made of a thermoplastic material. Alternatively, any of the stacking devices may be manufactured from any suitable rigid material such as glass, metal, wood, or any other similar materials. A preferable material will be rigid, inexpensive, and have the ability to be readily formed into a desired shape. Suitable plastic materials for any embodiment of the stacking device of the present invention include polypropylene, polyethylene, styrene, polystyrene, nylon, and a wide variety of other homopolymers and copolymers. Any suitable molding technique can be employed to form the stacking devices of the present invention, including but not limited to injection molding and thermoforming. The stacking devices are preferably integrally made but can also be formed in multiple parts that are snapped or pressed together during manufacture and assembly.
- The stacking devices can further have any geometric shape corresponding to the shape of the container inserted therein. For example, the stacking device may have a triangular shape or a rectangular shape for triangular and rectangular shaped containers, respectively. Alternatively, the device need not have a shape corresponding to the shape of the container. Such an arrangement is shown in FIG. 28, wherein round lid(s)70 and/or container(s) 71 are stored in the
device 130 of FIGS. 17-22. - FIG. 23 illustrates an embodiment of the present invention comprising a
device 200 including atriangular body member 202 made of a suitable plastic or other material. Thebody member 202 is preferably hollow and includes abase surface 204 andside surfaces base surface 204 may be secured to a shelf, countertop, pantry or closet surface or any other surface by any suitable means, such as double sided adhesive tape. The side surfaces 206, 208 may have a series of slots 210 formed therein. In the illustrated embodiment, six slots 210 a-210 f are formed in the side surfaces 206, 208, although a different number of slots may alternatively be provided. Each slot 210 a-210 f includes a main portion 212 a-212 f and an enlargedlower portion 214 a-214 f. One ormore lids 216 may be inserted into a corresponding number of the slots 210 such that thelids 216 are supported in a generally upright configuration as seen in FIG. 24. The enlargedlower portion 214 of each slot 210 accommodates an outer raised portion of thelid 216 when thelid 216 is tilted slightly to the side.
