DETAILED DESCRIPTION OF EMBODIMENTS

The present disclosure describes a container and lid assembly that provides evidence of the lid being tampered with/opened a first time.
Referring to FIG. 1, in one embodiment, is a container and lid assembly 10, comprising a separable container 12 and lid 14. Container 10 can be of virtually any shape and volume, while lid 12 is to shaped and sized to contour to and sealingly mate with/engage a corresponding lip of container 10.
Container 12 has a volume of space defined by an open top 16 and a floor 18 and upstanding walls 20, wherein the upstanding walls 20 comprise an upper flange, designated generally by reference numeral 22 that extends around the periphery of the container 12. Upper flange 22 generally comprises a first upwardly facing U-shaped region 24 defined by an upstanding outer wall 26 having an upper edge 28, an upstanding interior wall 30 having an upper edge 32 that extends in a first plane, P1, and a floor 34 that extends between the outer wall 26 and interior wall 30, wherein the outer wall 26 includes a protuberance 36 extending inwardly therefrom adjacent the upper edge 28. Upper flange 22 further comprises a downwardly facing U-shaped region 38 inwardly adjacent to the upwardly facing U-shaped region 24 and defined by the first upstanding interior wall 30, a second upstanding interior wall 40 positioned interiorly of the first upstanding interior wall 30 and having an upper edge 42 that extends in a second plane, P2, that is vertically spaced above the first plane P1, and a ceiling 44 that extends between the upper edge 32 of the first upstanding interior wall 30 and an intermediate position along the second interior upstanding wall 40. Upper flange 22 further comprises a tab 46 that is secured to the upper edge 28 of upstanding outer wall 26 and that is manually separable from therefrom, wherein when separated from the upstanding outer wall 26, an access space 48 is created in the upstanding outer wall to permit a user to grasp the lid 14 and pull it away from container 12. Container 12 further comprises a lip 49 that extends inwardly from second upstanding interior wall 40 which transitions into the upstanding walls 20.
The lid 14 generally comprises a peripheral flange region 50 that cooperatively fits with the upper flange 22 of the container 12 to provide a tamper evident seal. The peripheral flange region 50 comprises a lid having a first lid upwardly facing U-shaped region 52 that is shaped and sized to fit within and contour the first U-shaped region 22 of the container 12. The first lid upwardly facing U-shaped region 52 is defined by a lid outermost upstanding wall 54 that terminates at an upper edge 56, a first lid interior upstanding wall 58 that terminates in an upper edge 60, and a lid floor 62 that extends between the lid outermost upstanding wall 54 and the first lid interior upstanding wall 58, wherein when the lid 14 is attached to the container 12 the upper edge 56 of the lid outermost upstanding wall 54 is positioned in movingly blocked relation beneath the protuberance 36. The flange region 50 further comprises a lid downwardly facing U-shaped region 64 defined by a second upstanding interior wall 66 positioned laterally interiorly of the first lid upstanding interior wall 58 and having an upper edge 68, a third lid upstanding interior wall 70 having an upper edge 72, and a lid ceiling 74 that extends between the upper edges 68, 72 of the second upstanding interior wall 66 and third lid upstanding interior wall 70. The flange region 50 further comprises a lid transition region 76 that extends between the first lid upstanding interior wall 58 and the second upstanding interior wall 66. When the lid 14 is sealingly engaged in covering relation to the container 12, the upper edge of the first upstanding interior wall is positioned within the lid downwardly facing U-shaped region with an air gap 78 formed between the upper edge 68 of the second upstanding interior wall 66 and the ceiling 74 of the lid downwardly facing U-shaped region 64. When the lid 14 is sealingly engaged with the container 12, access to the upper edge 56 of the outermost upstanding wall 54 is prevented until the tab 46 is manually separated from the upper edge 56 of upstanding outer wall 54 (e.g., by tearing/breaking/snapping). A user can then access upper edge 56 via the air gap 48 and pull lid 14 from under protuberance 36 and separate it from cover 16. From third lid upstanding interior wall 70, lid 14 transitions along a floor 80 that sits upon lip 49 before transitioning into the body of lid 14.
In use, lid 14 mates with container 12 with protuberance 36 preventing/blocking lid 14 from being lifted out of covering relation to container 12. To initially gain access to the contents of container 12, a user would need to break tab 46 off of/away from container 12, thereby providing a user with access to the upper edge 56 and ability to pull upwardly and away from protuberance 36 and pry lid 14 off of container 12.
With reference to FIGS. 12-21, a container and lid assembly 100 is shown comprising a container 102 and lid 104 hingedly connected to one another for selective movement between covered and uncovered positions. Container and lid assembly 100 is shown as rectangular, but other shapes are possible as well. For example, with reference to FIGS. 21-28, a circular container and lid assembly 200 is shown comprising a container 202 and lid 204 hingedly connected to one another for selective movement between covered and uncovered positions. Other than their shape, container and lid assembly 100 and 200 are identical.
Container 102/202 and lid 104/204 are connected together by a living hinge 106/206, respectively, that include flanges 108/208 extending outwardly from an edge of container 102/202, and a flange 110/201 extending outwardly from an edge of lid 104/204. Hinge 106/206 is formed at the interface of flanges 108/208 and 110/210 to permit pivotal movement of the lid 104/204 relative to the container 102/202 about the hinge axis X-X.
With reference to FIGS. 19B and 28B, the sealing structure of containers 100/200 can be seen. Container 102/202 each include an upwardly turned U-shaped portion 112/212 at its outermost edge and which transitions to a downwardly turned U-shaped portion 114/214 radially inward from the upwardly turned U-shaped portion. A lip/flange 116/216 is formed on the inwardly directed surface of the outer leg of upwardly turned U-shaped portion 114/214 adjacent the upper edge. Lid 104/204 include a backwards J-shaped portion 118/218 at its outermost edge in contoured relation to U-shaped portion 112/212 and with the shorter, terminal edge of the outer leg of the J being positioned for snapping engagement beneath lip/flange 116/216 to secure the connection of the lid to the container. Moving radially inward from backwards J-shaped portion 118/218, lid 104/204 then transitions into a downwardly turned U-shaped portion 120/220 which contours with downwardly turned U-shaped portion 114/214 and with its inner leg having a stepped out portion 122/222 that creates an air gap 124/224 between itself and the inner leg of downwardly turned U-shaped portion 114/214 when the lid 104/204 is covering container 102/202. The air gap 124/224 creates a vacuum seal to more securely interconnect the lid to the container. In addition, at the top of the downwardly turned U-shaped portions 114/214 and 122/222, there is a slight rise before it turns downwardly along the inner leg that further serves to secure the interconnection.
As with assembly 10, a tab 126/226 is secured to the upper edge of the container's outermost edge. Tab 126/226 is manually separable from container 102/202 and when separated, an access space 128/228 is created in the upstanding outer wall to permit a user to grasp the lid 104/204 and pull it away from container 102/202 and provide evidence that the unit has been opened/tampered with as there is otherwise no easy way of removing the lid from the container.
