DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0051] The present disclosure is directed to a tamper evident seal mechanism for a jar and lid. In preferred examples, the jar and lid can both be made from plastic and cannot be opened without irreversibly breaking the seal mechanism. In one example, the jar includes a seal at a top end of the jar and includes a first securement mechanism and the lid includes a second securement mechanism that engages the first securement mechanism. The lid cannot be removed from the jar until the first securement mechanism is detached from the jar, ensuring that the jar seal is not broken if the first securement mechanism is still present.
Tamper-Resistant Jar and Lid
[0052]
[0053] Additionally, the lid 104, discussed in greater detail below in connection with respect to
[0054] In the present example, each of the jar 102 and the lid 104 of the tamper-resistant jar and lid 100 are made of a polymer. In some examples, the jar 102 and the lid 104 are made of the same polymer. In other examples, the jar 102 could be made of a first polymer and the lid 104 is made of a second polymer, different from the first polymer. Further, in various other examples, the jar 102 and the lid 104 can be made of other materials. The jar 102 and the lid 104 can be made of glass, metal, or nature-based materials. For example, the jar 102 can be glass and the lid 104 can be metal.
Jar
[0055]
[0056] The jar 102 further includes a tab 220 removably coupled to the jar 102 by at least one frangible connection (shown in
[0057] Additionally, the jar 102 includes a flange 230 disposed on the outer surface 212 of the jar wall 210. The flange 230 extends radially outward from the outer surface 212 of the jar wall 210 and circumscribes most or all of the jar 102. In the present example, the tab 220 is removably coupled with the jar 102 via the at least one frangible connection removably coupled with the flange 230.
[0058] Further, the jar 102 includes a first helical thread 240 disposed on the jar wall 210 between the top edge 208 and the first securement mechanism 222 and the flange 230. In the present example, the jar 102 includes a single helical thread 240, but in other examples, the jar 102 could include two or more helical threads 240 coextensive on the jar wall 210.
[0059]
[0060]
[0061] The tab 220 is selectively secured to the jar 102 and the flange 230 via frangible connections 410. For example, the tab 220 includes a first frangible connection 412 selectively securing the tab 220 to an outer surface 212 of the jar 102. Additionally, the tab 220 includes a second frangible connection 414 and a third frangible connection 416 (shown in
[0062]
[0063] As also shown in
[0064] The top edge 208 of the jar 102 further includes a circumferential wiper 522. As will be discussed in greater detail in connection with
Lid
[0065]
[0066] In the present example, the sidewall 604 includes a textured surface 612. The textured surface 612 is configured to increase grip on the surface and improve traction between a user's hand and the lid 104. As shown in
[0067] As shown in
[0068] In the present example, the second securement mechanism 702 is configured to engage the first securement mechanism 222 when the lid 104 encloses the top end 206 of the jar 102. In the present example, the second securement mechanism 702 defines a second set of teeth 722. As shown in
[0069] Additionally, as illustrated in
[0070]
[0071] In the present example, the sealing surface 802 is a generally flat surface disposed between the circumferential flange 804 and the inner surface 712 of the lid 104. In the present example, the sealing surface 802 is perpendicular to the inner surface 712. In a preferred example, the sealing surface 802 is rigid and does not deform under normal axial loads when closing the lid 104 on the jar 102.
[0072] The circumferential flange 804, which serves as a sealing flange, extends from the top wall 602 of the lid 104. In preferred examples, the circumferential flange 804 is at least partially flexible or partially deformable under a radial load. As a result, the circumferential flange 804 can deform and form a liquid-tight and airtight seal. The circumferential flange 804 includes a curved, engagement surface 812. The engagement surface 812 is configured to engage with the inner surface 214 of the jar wall 210 and deflect radially inward (as will be discussed in greater detail in connection with
Operation of the Securement Mechanism
[0073]
[0074] In the present example, the first and second sets of teeth 224, 722 are complementary to each other. For example, each tooth of the first and second sets of teeth 224, 722 includes angled surfaces. In the present example, each tooth of the first set of teeth 224 includes a first angled surface 912 disposed at a first angle 914 and a second angled surface 916 disposed at a second angle 918. Similarly, each tooth of the second set of teeth 722 includes a first angled surface 922 disposed at a first angle 924 and a second angled surface 926 disposed at a second angle 928. The first angled surfaces 912, 922 permit the first and second sets of teeth 224, 722 to slide over each other and the second angled surfaces 916, 926 inhibit the first and second sets of teeth 224, 722 from sliding over each other (discussed in greater detail below).
[0075] In the present example, the first angles 914, 924 are approximately 45. In some examples, the first angles 914, 924 can be greater or less than approximately 45. In various examples, the first angle 914 can be a different angle than the first angle 924. For example, the first angle 914 can be approximately 30 and the first angle 924 can be approximately 60. In the foregoing examples, the first angles 914, 924 are configured to facilitate the first and second sets of teeth 224, 722 passing over each other when twisted in a closing direction 932.
[0076] Also, the second angles 918, 928 are approximately 90. In some examples, the second angles 918, 928 can be greater than approximately 90or less than approximately 90. Additionally, in some examples, the second angles 918, 928 can be a different angle than the second angle 928. For example, the second angle 918 can be approximately 110and the second angle 928 can be approximately 70. In any of the foregoing examples, the second angles 918, 918 are configured to inhibit the first and second sets of teeth 224, 722 from passing over each other when twisted in an opening direction 934. When the second angles 918, 928 are 90, the first and second sets of teeth 224, 722 abut each other and prevent the lid 104 from disengaging from the jar 102. Alternatively, the second angles 918, 928, when larger than 90, can facilitate the first and second sets of teeth 224, 722 interlocking and preventing first and second sets of teeth 224, 722 from passing over each other when twisted in the opening direction 934.
Dual Seal Mechanism
[0077]
[0078] The first seal 1012 is between the top edge 208 of the jar 102 and the sealing surface 802 of the lid 104. In preferred examples, the circumferential wiper 522 deforms under an axial load between the lid 104 and the top edge 208. The deformed circumferential wiper 522 ensures a watertight and/or an airtight seal along the entire circumference of the top edge 208 of the jar 102.
[0079] The second seal 1014 is between the engagement surface 812 of the circumferential flange 804 and the inner surface 214 of the jar wall 210. In the present example, the inner surface 214 exerts an inwardly directed radial force on the circumferential flange 804. The circumferential flange 804 seals against the inner surface 214 in response to the inwardly directed radial force. In some examples, the circumferential flange 804 deforms by deflecting radially inward. In other examples, the circumferential flange 804 deforms in shape and the curved engagement surface 812 flattens against the inner surface 214.
First Alternate Jar and Lid Design
[0080]
[0081] The jar 1102 includes a tab 1120 removably coupled to the jar 1102 by at least one frangible connection (substantially identical to the frangible connections described above). The tab 1120 includes a first securement mechanism 1122, defining a first set of teeth 1124, and a leverage surface 1126. As shown in
[0082] Additionally, the jar 1102 includes a stepped surface 1152 defined by steps 1154 disposed in the jar wall 1112. In some examples, the stepped surface 1152 is disposed radially inward relative to the jar wall 1112. As a result, the jar wall 1112 defined by the stepped surface 1152 is thinner than adjacent portions of the jar wall 1112 in order to facilitate proper plastic injection tooling. For example, in order to facilitate the formation of a frangible connection between the tab 1120 and the jar wall 1110. For example, the step 1154 can be between 0.002 in. and 0.01 in. In various other examples, the step 1154 can be larger or smaller. Additionally, in some examples, the step 1154 can be tapered such that the step 1154 is larger along the top edge 1108 and smaller near the flange 1130.
[0083] As illustrated in
[0084] As discussed above, the second securement mechanism 1202 can be disposed in discrete segments. In the present example, the lid 1200 includes two second securement mechanisms 1202. In the present example, each of the second securement mechanisms 1202 defines an arclength 1226 of approximately 1.25 in. In various other examples, the arclength 1226 between approximately 0.5 in. and 3 in. In various examples, the arclength of the first securement mechanism 1122 can be between 0.25 in. and 3.5 in. In preferred examples, the arclength 1226 of the second securement mechanism 1202 is longer than the arclength first securement mechanism 1122, but in other examples, the arclength of the first securement mechanism 1122 can be longer than the arclength 1226 of the second securement mechanism 1202.
[0085] The present tamper-resistant jar and lid 100 provides several benefits over other tamper-resistant jars. First, the tamper-resistant jar and lid 100 includes a very economical and straightforward tamper-resistant and tamper evident sealing mechanism. Second, the tamper-resistant jar and lid 100 includes a redundant dual seal mechanism 1002 to ensure the jar 102 properly maintains a seal and protects the contents of the jar 102.
[0086] The tamper-resistant jar and lid 100 can be made entirely of a plastic polymer and doesn't require the use of expensive glass or metal. The securement mechanism is also very straightforward because the presence of the tabs 220 still on the jar 102 visibly indicates the seal has been maintained and the tabs are easily visible upon inspection of the tamper-resistant jar and lid 100.
[0087] The dual seal mechanism 1002 improves the seal between the jar 102 and the lid 104. This further protects the contents of the jar 102 from being exposed to an exterior environment. The dual seal mechanism 1002 can also provide redundancy to ensure the seal is maintained if one of the two seals fails.
Second Alternate Jar and Lid Design
[0088] Turning to
[0089] The tab 2220 includes an outside wall 2260, which is spaced radially outwardly of the first set of teeth 2224 and engages at least a lower lip 2604a of the side wall 2604 of the lid 2104 when fully closed, with the first set of teeth 2224 and the outside wall 2260 defining a channel 2250 therebetween that receives the lower lip 2604a of the side wall 2604. The tab 2220 is further provided with at least a pair of ribs 2262, 2264 that extend inwardly from the first set of teeth 2224. Each of the ribs 2262, 2264 may taper inwardly adjacent the outer surface 2212 of the jar wall 2210, and while integral with the tab 2220 and in abutting contact with the outer surface 2212 of the jar wall 2210, is not otherwise physically bonded to the outer surface 2212 of the jar wall 2210.
[0090] The ribs 2262, 2264 serve to add strength to the breakable tab 2220, helping to prevent tampering by pulling gently on the bottom of the tab while pivoting the first set of teeth 2224 inward in an effort to disengage them from the second set of teeth 1722 of the lid 2104.
[0091] The jar 2102 is also provided with an annular skirt 2270 extending substantially about a perimeter of the jar wall 2210, but terminating on either side of the tab 2220. The annular skirt 2270 is connected to jar wall 2210 by a plurality of radially-extending ribs 2272. The annular skirt 2270 provides additional stiffness and hoop strength.
