In accordance with various embodiments, reclosable can ends are provided.

In some embodiments, reclosable can ends are described herein. In some embodiments, a reclosable can end can be part of any suitable type of can, such as a soda can, that can be used to store any suitable type of liquid or beverage, or a can that can be used for any other suitable cannable storage needs.

In some embodiments, a can that includes a reclosable can end can be opened. For example, in some embodiments, a lid base of the can end (e.g., a flat top portion of the can end) can be opened such that a scored flap of the lid base is pressed inward to expose an opening in the lid base. In some embodiments, a scored flap can be pressed inward in any suitable manner, such as by using a tab attached to the lid base that can act as a lever to apply pressure to the scored portion, thereby breaking a perforated border of the scored flap and lid base.

In some embodiments, the tab can be coupled to a closure flap that has a size and dimensions corresponding to an opening in the lid base such that the closure flap can be turned and then pressed into the opening to close the opening in the lid base, thereby providing a seal in the opening in the lid base. In some embodiments, the closure flap can be pulled and/or rotated out of the opening to open the lid base. Continuing further, in some embodiments, the closure flap can be reinserted in the lid base to reclose the opening in the lid base. In some embodiments, the closure flap can be inserted and rotated from an opening of an opened can any suitable number of times while still maintaining a seal over the opening.

In some embodiments, a tab can be coupled to a closure flap and attached to a lid base of a can end in any suitable manner. For example, in some embodiments, a tab can be coupled to a closure flap and attached to a lid base via a rivet made from a raised center area of the lid base, as shown in and described below in connection with. As another example, in some embodiments, a tab can be coupled to a closure flap and attached to a lid base via a rivet made from a raised center area of the tab, such as shown in and described below in connection with. As yet another example, in some embodiments, a tab can be coupled to a closure flap and attached to a lid base via an independent rivet, such as shown in and described below in connection with. In some embodiments, any suitable mechanism can be used to couple a tab to a closure flap and to attach the coupled tab and closure flap to a lid base, which can allow the tab and the closure flap to lock and rotate together.

Note that, in some embodiments, “can end” can refer to a top portion of a can. In some embodiments, a can end can include any suitable elements, such as a lid base (e.g., a flat portion of a can end with shaped edges to allow the can end to attach to a can body), a scored flap corresponding to an opening in the lid base when the can has been opened, a closure flap, a tab, and/or any suitable rivets. Additionally, note that, in some embodiments, lid bases, closure flaps, tabs, and rivet(s) as described herein can be manufactured for can ends of any suitable size.

In some embodiments, a closure flap, a tab, and any rivet(s) can remain attached to a can, thereby reducing litter and protecting consumers and animals from abrasions due to any sharp and/or metal edges. Additionally, in some embodiments, any suitable portions of a closure flap, a tab, rivet(s), a lid base, and/or any other suitable elements of a can end can be made from any suitable materials (e.g., aluminum and/or aluminum alloy as used in a can body), thereby allowing the closure flap, the tab, the rivet(s), and/or the lid base to be recycled.

Turning to, top views of examples of reclosable can ends are shown in accordance with some embodiments of the disclosed subject matter.shows an example of a lid basethat has not yet been opened. Note that, in some embodiments, a can end can be made of any suitable material, such as aluminum, an aluminum alloy, steel, and/or any other suitable materials. Additionally, note that, in some embodiments, a body of a can can be made of a different material than a can end. In some embodiments, an internal portion of a can end can be coated with any suitable material or combination of materials. For example, in some embodiments, an internal portion of the can end can be coated with epoxy resin. As another example, in some embodiments, an internal portion of the can end can be coated with a polymer plastic lining that is made of any suitable material or combination of materials (e.g., polyethylene, polypropylene, polyester, styrene, acrylic, vinyl, and/or any other suitable material(s)).

As illustrated,includes a tab, a closure flap, a tab rivet area, lid base, and a scored flap. Note that, as shown in, scored flapis fully attached to lid base, because tabhas not yet caused scored flapto separate from a top portion of lid base. In some embodiments, tabcan be connected to any suitable portion of lid base(e.g., a center portion, and/or any other suitable portion) in any suitable manner. For example, in some embodiments, tabcan be connected to lid basevia a rivet in tab rivet area. Note that, in some such embodiments, a rivet in tab rivet areacan be a rivet that is part of lid base(e.g., as shown in and described below in connection with, and/orC), a rivet that is part of tabin tab rivet area(e.g., as shown in and described below in connection with), and/or an independent rivet inserted in tab rivet area(e.g., as shown in and described below in connection with).

In some embodiments, tabcan cause a portion of scored flapto at least partially separate from lid base, thereby opening lid base, as illustrated in. In some embodiments, opening lid basecan cause an openingof lid baseto be exposed. In some embodiments, tabcan cause the portion of scored flapto separate from lid basein any suitable manner. For example, in some embodiments, a tip of tabthat is above scored flapcan be pressed into scored flap, thereby causing a portion of scored flapto be pressed into an interior of a can body attached to lid base. In some embodiments, the tip of tabcan be pressed into scored flapin any suitable manner. For example, in some embodiments, tabcan be operated as a second class lever and a first class lever around a corresponding to tab rivet areaby lifting a back end of tabthat is opposite the tip of tab, thereby causing the tip of tabto apply pressure to scored flap.

As shown in, in some embodiments, tabcan be connected to a closure flapin any suitable manner including a rivet, welding, recyclable sealant, rubber, recyclable glue, links, and/or in any other suitable manner. For example, in some embodiments, tabcan be connected to closure flapvia a rivet corresponding to tab rivet area. Note that, in some embodiments, the rivet corresponding to tab rivet areacan be part of lid base(e.g., as shown in and described below in connection with), part of tab(e.g., as shown in and described below in connection with), and/or an independent rivet (e.g., as shown in and described below in connection with).

As shown in, in some embodiments, closure flapcan have a size and a shape that corresponds to opening, thereby allowing closure flapto be inserted into openingto re-close and seal lid baseafter scored flapof lid basehas been opened.

Note that, as shown in, tabcan be joined by a rivet corresponding to tab rivet area, thereby allowing tabto rotate in conjunction with closure flap, either clockwise or counterclockwise. For example, in some embodiments, closure flapcan be rotated to a position suitable for insertion of closure flapinto openingto seal opening.

Additionally, note that, in some embodiments, scored flapcan have any suitable size and/or any suitable shape depressions. In some embodiments, scored flapcan be scored or perforated to allow a portion of scored flapto separate from lid basewhen a tip of tabis depressed on scored flapto open lid base. Note that, when opened, in some embodiments, scored flapcan remain attached to lid basevia a link. In some embodiments, any suitable portion of scored flap, link, and/or lid basecan be scored or perforated to allow any portion of scored flapto bend from lid basewhen lid baseis opened to allow the portion of scored flapto remain attached to lid basewhile providing a seal between closure flapand opening.

In some embodiments, scored flapcan be scored in multiple ways around a circumference of openingand at link. In some embodiments, scored flap, where it meets link, can curl upward and inward toward the center of lid base, such as shown in and described below in connection with. As another example, in some embodiments, scored flap, where it meets link, can be scored such that it is a dead end stop with no curl as shown in and described below in connection with. As yet another example, in some embodiments, scored flap, where it meets link, can be scored such that it can curl down and inward toward the center of scored flapas shown in and described below in connection with.

In some embodiments, an underside of linkcan be perforated in any suitable manner (e.g., as shown in and described below in connection with) to create a more desirable angle to provide a seal of closure flapover openingof lid baseand link. For example, in some embodiments, the underside of linkadjacent to a point at which linkconnects to lid basewhen lid baseis open can have small cuts or indents such that scored flapbends around the perforations of linkwhen lid baseis open. In some embodiments, a depth of the perforations of the underside of linkcan be deep enough to allow scored flapto bend straight inward into openingand around linkarea but shallow enough that linkremains connected to lid basewhen lid baseis opened.
