[0028] According to various embodiments, a resealable can end is provided.

[0029] In some embodiments, a resealable can end is described herein. In some embodiments, the resealable can end can be part of any suitable type of can, such as a soda can, which can be used to store any suitable type of liquid or beverage, or can be used for any other suitable canning storage needs.

[0030] In some embodiments, the can, including the resealable can end, can be opened. For example, in some embodiments, the cap base of the can end (e.g., the flat top portion of the can end) can be opened such that a scored tab of the cap base is pressed inward to expose an opening in the cap base. In some embodiments, the scored tab can be pressed inward in any suitable manner, such as by using a pull tab attached to the cap base (which can act as a lever to apply pressure to the scored portion), thereby disrupting the indentation boundary between the scored tab and the cap base.

[0031] In some embodiments, the pull tab may be coupled to a sealing flap, the size and dimensions of which correspond to an opening in the lid body, such that the sealing flap can be rotated and subsequently pressed into the opening to close the opening in the lid body, thereby providing a seal in the opening in the lid body. In some embodiments, the sealing flap can be pulled out and / or rotated out of the opening to open the lid body. Further, in some embodiments, the sealing flap can be reinserted into the lid body to re-close the opening in the lid body. In some embodiments, the sealing flap can be inserted and rotated from the opening of an open can any suitable number of times while still maintaining a seal at the opening.

[0032] In some embodiments, the pull tab may be coupled to the closure tab and attached to the lid base at the end of the can in any suitable manner. For example, in some embodiments, the pull tab may be coupled to the closure tab and attached to the lid base via a rivet formed by a raised central region of the lid base, as described below. Figure 10A , Figure 10B and Figure 10C As shown and described. As another example, in some embodiments, the pull tab may be coupled to the closure cover and attached to the cover base via a rivet made of the raised central region of the pull tab, such as in the following description. Figure 3E As shown and described. As another example, in some embodiments, the pull ring may be coupled to the closure tab and attached to the cover base via separate rivets, such as those described below. Figure 4A , Figure 4B and Figure 4C As shown and described. In some embodiments, any suitable mechanism may be used to attach the pull ring to the closure tab and attach the attached pull ring and closure tab to the cover base, which allows the pull ring and closure tab to lock and rotate together.

[0033] It should be noted that in some embodiments, "can end" may refer to the top portion of the can. In some embodiments, the can end may include any suitable elements, such as a lid base (e.g., a flat portion of the can end having shaped edges to allow the can end to attach to the can body), a notched lid corresponding to an opening in the lid base when the can is opened, a closing lid, a pull tab, and / or any suitable rivet. Furthermore, it should be noted that in some embodiments, the lid base, closing lid, pull tab, and rivet as described herein may be manufactured for can ends of any suitable size.

[0034] In some embodiments, the closure tab, pull tab, and any rivets may remain attached to the can, thereby reducing waste and protecting consumers and animals from scratches caused by any sharp and / or metal edges. Furthermore, in some embodiments, any suitable portion of the closure tab, pull tab, rivets, lid base, and / or any other suitable element at the end of the can may be made of any suitable material (e.g., aluminum and / or aluminum alloys used within the can body), thereby allowing for the recycling of the closure tab, pull tab, rivets, and / or lid base.

[0035] Go to Figure 1A and Figure 1B According to some embodiments of the subject matter of this disclosure, a top view of an example of a resealable end of a can is shown. Figure 1A An example of an unopened lid base 100 is shown. It should be noted that in some embodiments, the can end may be made of any suitable material, such as aluminum, aluminum alloy, steel, and / or any other suitable material. It should also be noted that in some embodiments, the can body may be made of a different material than the can end. In some embodiments, the inner portion of the can end may be coated with any suitable material or combination of materials. For example, in some embodiments, the inner portion of the can end may be coated with epoxy resin. As another example, in some embodiments, the inner portion of the can end may be coated with a polymer plastic liner made of any suitable material or combination of materials (e.g., polyethylene, polypropylene, polyester, styrene, acrylic, vinyl, and / or any other suitable material).

[0036] As shown in the figure Figure 1A This includes a pull ring 102, a closing cover 108, a pull ring rivet area 110, a cover base 100, and a notched cover 104. Note that, as... Figure 1A As shown, the notched cover 104 is fully attached to the cover base 100 because the pull ring 102 has not yet detached the notched cover 104 from the top portion of the cover base 100. In some embodiments, the pull ring 102 may be attached to any suitable portion of the cover base 100 (e.g., the central portion, and / or any other suitable portion) in any suitable manner. For example, in some embodiments, the pull ring 102 may be attached to the cover base 100 via a rivet in the pull ring rivet region 110. It should be noted that in some such embodiments, the rivet in the pull ring rivet region 110 may be a rivet that is part of the cover base 100 (e.g., as described below). Figure 10A , Figure 10B and / or Figure 10C (Shown and described), is a portion of the pull ring 102 in the pull ring rivet region 110 (e.g., as described below). Figure 3E The rivet and / or pull ring rivet area 110 (shown and described) (e.g., as combined below) Figure 4A , Figure 4B and Figure 4C The individual rivets shown and described.

[0037] In some embodiments, such as Figure 1B As shown, the pull tab 102 can cause a portion of the scored cover 104 to separate at least partially from the cover base 100, thereby opening the cover base 100. In some embodiments, opening the cover base 100 can expose an opening 106 in the cover base 100. In some embodiments, the pull tab 102 can separate a portion of the scored cover 104 from the cover base 100 in any suitable manner. For example, in some embodiments, the tip of the pull tab 102 located above the scored cover 104 can be pressed into the scored cover 104, thereby causing a portion of the scored cover 104 to be pressed into the interior of the can body attached to the cover base 100. In some embodiments, the tip of the pull tab 102 can be pressed into the scored cover 104 in any suitable manner. For example, in some embodiments, by lifting the rear end of the pull ring 102 (opposite to the tip of the pull ring 102), the pull ring 102 can be operated as a first type of lever and a second type of lever corresponding to the area around the pull ring rivet region 110, thereby causing the tip of the pull ring 102 to apply pressure to the notched cover 104.

[0038] like Figure 1B As shown, in some embodiments, the pull ring 102 can be connected to the closure cover 108 in any suitable manner, including rivets, welding, recyclable sealants, rubber, recyclable adhesives, connectors, and / or any other suitable method. For example, in some embodiments, the pull ring 102 can be connected to the closure cover 108 via rivets corresponding to the pull ring rivet region 110. It should be noted that in some embodiments, the rivets corresponding to the pull ring rivet region 110 can be part of the cover base 100 (e.g., as described below). Figure 10A (shown and described), a portion of pull ring 102 (e.g., as shown in the following combination) Figure 3E (as shown and described), and / or individual rivets (e.g., as combined below) Figure 4A , Figure 4B and Figure 4C (as shown and described).

[0039] like Figure 1B As shown, in some embodiments, the closure cover 108 may have a size and shape corresponding to the opening 106, thereby allowing the closure cover 108 to be inserted into the opening 106 to reclose and seal the cover base 100 after the scored cover 104 of the cover base 100 has been opened.

[0040] It should be noted that, such as Figure 1BAs shown, the pull ring 102 can be engaged by rivets corresponding to the pull ring rivet area 110, thereby allowing the pull ring 102 to rotate clockwise or counterclockwise together with the closure cover 108. For example, in some embodiments, the closure cover 108 can be rotated to a position suitable for inserting the closure cover 108 into the opening 106 to seal the opening 106.

[0041] Furthermore, it should be noted that in some embodiments, the perforated cover 104 may have recesses of any suitable size and / or any suitable shape. In some embodiments, the perforated cover 104 may be perforated or perforated to allow a portion of the perforated cover 104 to separate from the cover base 100 when the tip of the pull ring 102 is pressed against the perforated cover 104 to open the cover base 100. It should be noted that in some embodiments, the perforated cover 104 may remain attached to the cover base 100 via the connecting portion 112 when opened. In some embodiments, the perforated cover 104, the connecting portion 112, and / or any suitable portion of the cover base 100 may be perforated or perforated to allow any portion of the perforated cover 104 to bend from the cover base 100 when the cover base 100 is opened, thereby keeping a portion of the perforated cover 104 attached to the cover base 100 while providing a seal between the closing cover 108 and the opening 106.

[0042] In some embodiments, the notched cover 104 may be notched around the periphery of the opening 106 and at the connection 112 in various ways. In some embodiments, the notched cover 104 connected to the connection 112 may be rolled upward and inward toward the center of the cover base 100, for example, as described below. Figure 5C As shown and described. As another example, in some embodiments, the notched cover 104 that engages with the connection portion 112 may be notched to make it a non-curling end stop, as described below. Figure 5A As shown and described. As yet another example, in some embodiments, the notched cover 104 connected to the connecting portion 112 may be notched so that it can be curled downward and inward toward the center of the notched cover 104, as described below. Figure 5D As shown and described.

[0043] In some embodiments, the lower side of the connecting portion 112 may be recessed in any suitable manner (e.g., as described below). Figure 5B(As shown and described) to form a more ideal angle, thereby providing a seal of the cover 108 over the opening 106 and the connection 112 of the cover base 100. For example, in some embodiments, the underside of the connection 112 (adjacent to the point where the connection 112 connects to the cover base 100) may have a smaller cut or notch when the cover base 100 is opened, such that the notched cover 104 bends around the notch of the connection 112 when the cover base 100 is opened. In some embodiments, the depth of the notch on the underside of the connection 112 may be deep enough to allow the notched cover 104 to bend directly inward around the area of ​​the connection 112 into the opening 106, but shallow enough so that the connection 112 remains connected to the cover base 100 when the cover base 100 is opened.

[0044] Go to Figure 2A According to some embodiments of the subject matter of this disclosure, examples of a cover base 100 without a pull ring are shown when the cover base 100 is not yet opened (i.e., the notched cover 104 is not yet pressed). It should be noted that, as Figure 2A As shown, when the closure cover 108 is not in use, the closure cover 108 can be positioned in a portion of the cover base 100 (e.g., a recessed portion and / or any other suitable portion).

[0045] Go to Figure 2B According to some embodiments of the subject matter of this disclosure, an example of a cover base 100 without a pull ring and a closing cover is shown when the cover base 100 is not yet opened.

[0046] It should be noted that in some embodiments, the cover base 100 may include a liquid collection section 208 (e.g., capturing liquid flowing out of the opening of the cover base 100 when opened), a cover base cavity 210, a cover base rivet area 204, and an edge 212.

[0047] In some embodiments, the liquid collection portion 208 of the cover base 100 may have any suitable cover base cavity 210, having any type of recess, angle, edge, shape, arch, depth, and width. In some embodiments, the cover base cavity 210 may serve as a retaining area for the closure flap before the cover base 100 is opened or when the cover base 100 is reopened. In some embodiments, the cover base cavity 210 may be located below the closure flap and may be exposed once the closure flap is rotated.

[0048] In some embodiments, the collection portion 208 may have a width or depth sufficient to accommodate the opening or closing of the lid base 100. As a more specific example, where the opening of the lid base 100 is wider than that of a conventional soft drink can, the collection portion 208 of the lid base 100 may be relatively wider and more elliptical than the collection portion at the end of a conventional can. In some embodiments, the collection portion 208 may include a liner of any suitable type of material.

[0049] refer to Figure 2A and Figure 2B According to some embodiments of the subject matter of this disclosure, a closure cover (e.g., as shown) is illustrated. Figure 2A The closure cover 108 shown) and the cover base (e.g., as shown) Figure 2B The shape of the rivet area of ​​the cover base 100 shown. For example, refer to Figure 2A In some embodiments, any suitable rivet may be inserted into the closure cover rivet area 202 to attach the closure cover 108 to the pull ring (not shown). Note that in some embodiments, the rivet inserted into the closure cover rivet area 202 may be any suitable rivet, such as a rivet that is part of the pull ring (e.g., as described below). Figure 3E (as shown and described below) rivets that are part of the cover base (e.g., as shown and described below in conjunction with Figure 10) and / or separate rivets (e.g., as shown below in conjunction with Figure 10) Figure 4A , Figure 4B and Figure 4C (As shown and described). Furthermore, it should be noted that although the closed cover rivet area 202 is shown as triangular, in some embodiments, the closed cover rivet area 202 may have any suitable shape (e.g., square, circular, hexagonal, and / or any other suitable shape).

[0050] As another example, see Figure 2B In some embodiments, any suitable rivet can be used in the rivet area 204 of the cover base to connect the cover base 100 to the pull ring and the closing cover. It should be noted that in some embodiments, the rivet can be a rivet located on the cover base 100 at the rivet area 204 of the cover base (e.g., as described below). Figure 10A , Figure 10B and / or Figure 10C (As shown and described), the rivet may be part of a pull ring that passes through the rivet area 204 of the closed cover plate and the cover base (e.g., as described below). Figure 3E (shown and described) and / or individual rivets (e.g., as combined below) Figure 4A , Figure 4B and Figure 4C(As shown and described). Furthermore, it should be noted that although the cover base rivet area 204 is shown as circular, in some embodiments, the cover base rivet area 204 can be any suitable shape (e.g., square, triangular, hexagonal, and / or any other suitable shape). In some embodiments, the cover base rivet area 204 can be smaller or larger than the closing cover rivet area 202.

[0051] It should be noted that, although the above text combines... Figure 1A , Figure 1B , Figure 2A and Figure 2B Pull ring 102, closure tab 108, and cover base 100 are shown and described, but in some embodiments, any suitable alternative designs for the pull ring, closure tab, cover base, and rivet can be used in any suitable combination. For example, in some embodiments, alternative pull ring designs (e.g., as combined below) Figure 3A , Figure 3B , Figure 3C , Figure 3D , Figure 3E , Figure 9A and / or Figure 9F (As shown and described), replaceable closure cover designs (e.g., as combined below) Figure 6A , Figure 6B , Figure 6C , Figure 7A , Figure 7B , Figure 7C , Figure 8 , Figure 9A , Figure 9B , Figure 9C , Figure 9D and / or Figure 11 (As shown and described), alternative rivet designs (e.g., as combined below) Figure 4A , Figure 4B , Figure 4C , Figure 9A , Figure 9B , Figure 9C , Figure 9D , Figure 9E , Figure 9F , Figure 9G , Figure 10A , Figure 10B and / or Figure 10C (shown and described) and / or alternative cover substrate designs (e.g., as combined below) Figure 10A , Figure 10B , Figure 10C and / or Figure 11 (As shown and described) can be used in any suitable combination.

Furthermore, it should be noted that... Figure 7A , Figure 7B and Figure 7C In the middle, the outer edge 609 of each closed cover is shown on the top of the cover base 100.

[0070] Note that in some embodiments, the closure and / or the raised portion on the closure may be made of any suitable material. For example, in some embodiments, the closure and / or the raised portion may be made of the same material as the can, such as aluminum or an aluminum alloy. In some embodiments, the closure and / or the raised portion on the closure may be made of any suitable material that allows the closure and / or the raised portion to be recycled together with the can.

[0071] Additionally, it should be noted that in some embodiments, the center of the sealing cover may have a recessed cavity (e.g., as shown in the image). Figure 7A The recessed cavity 708 shown has a center dimension corresponding to the opening dimension of an open can (e.g., as described above). Figure 1B The opening 106 shown and described.

[0072] In some embodiments, the bottom portion of the closure cover may have a lining seal of any suitable material (e.g., such as...). Figure 7AThe lining seal 710 shown may be, for example, the same coating as the interior of the can body or any other suitable material. Note that in some embodiments, any suitable type of seal may be used, such as a seal for the lining or interior of the can (e.g., epoxy, any suitable polymer plastic, and / or any other suitable seal). In some embodiments, the seal may be any suitable seal that meets any suitable criteria, such as being harmless to consumers (e.g., BPA-free, and / or any other suitable harmless seal), recyclable with aluminum, not contaminating and / or altering the taste of the beverage in the can, and / or meeting any other suitable criteria. In some embodiments, the lining seal may have any suitable layer and / or may have any suitable thickness, which may help seal openings at the can ends and / or contribute to ease of use. In some embodiments, the lining seal may have any suitable size to correspond to a portion of the bottom of the corresponding closure flap or to the entire bottom of the corresponding closure flap. Additionally or alternatively, it should be noted that in some embodiments, a destructible seal may be used to cover the closure flap before first use to prevent contaminants from entering the area beneath the closure flap.

[0073] Go to Figure 8 According to some embodiments of the subject matter of this disclosure, exemplary cross-sectional side views of closure flaps of different shapes are shown. As illustrated, eight shapes 802, 804, 806, 808, 810, 812, 814, and 816 are shown, offering multiple design options and / or combinations thereof. It should be noted that, as Figure 8 As shown, the closure cover can have any suitable size and any suitable shape, including any suitable angle, cut, edge, pad, groove, mold, lip, pressure point, curl and / or any other suitable design.

[0074] In some embodiments, the closure cover may have a segment including the following: 1.) a recessed cavity 708 (as described above) Figure 7A 1) As shown and described above; 2.) Closed sealing locking region 826; and 3.) Outer edge 609 (as shown and described above in conjunction with FIG. 6). For example, in some embodiments, the recessed cavity 708 may be of various depths, angles, shapes, and / or widths relating to the closed sealing locking region 826 to be inserted into the interior of the cover base opening and / or into the cover base cavity (e.g., Figure 2B The cover base cavity 210) is located inside the holding area, thereby accommodating the movement of the cover (e.g., during the rotation or positioning of the cover during opening or closing) and / or facilitating the insertion of the cover into the cover base opening.

[0075] As another example, in some embodiments, as shown in shapes 812, 814, and 816, the closure flap may include a straight edge 818 that connects to an angle drop 819 at any suitable angle (e.g., 40°, 45°, 50°, and / or any other suitable angle), which results in a lower cut / notch 820 serving as a hook. In some embodiments, once the cover base 100 is opened, the lower cut / notch 820 may be located below the edge of the opening 106. In some embodiments, this may allow the closure flap to be sealed over the opening 106 such that the seal does not interfere with the connection 112, but rather allows the closure flap to work in conjunction with the connection 112 to seal the cover base opening.

[0076] As yet another example, in some embodiments, the outer edge 609 of shape 814 can act like a spring when the closure tab is pressed down in the middle via the attached pull ring, providing resistance or assistance as the closure tab is pressed into the opening of the cover body and / or as the closure tab is rotated by the attached pull ring. It should be noted that shape 814 includes an upward arch and a downward bend 822 forming a curled edge 824 that can retract below the arch 822 and may be located on top of the liquid collection portion of the cover body. This can be used to provide a spring-like effect, resistance, pressure, and / or any other suitable function to assist the closure tab at the junction of the cover body opening and the cover body opening (e.g., as described above). Figure 1B A tight and leak-proof seal on the connection 112 shown and described. Furthermore, in some embodiments, the curled edge 824 may provide a smooth surface area for the outer edge 609 of the closure cover, so that the closure cover has no scratching edges.

[0077] In some embodiments, the cover body may have a sliding region in which the closing cover can move during rotation of the closing cover into and out of the cover body opening. In some embodiments, the sliding region may facilitate movement and / or rotation of the closing cover.
