Resealable beverage can end and methods relating to same

1. A can end combination comprising a metal can end and resealable closure coupled to the can end,

the can end comprising a peripheral wall and a center panel, the center panel including an upper surface, an opposing lower surface, and an aperture formed therethrough;

the closure comprising a base plate and a top plate coupled to the base plate at a first location, the base plate includes a bead, the closure having (i) a sealed position in which at least one of the base plate and top plate contact the center panel about the aperture to form a seal, (ii) an intermediate position in which the closure is proximate the aperture but not sealed, and (iii) a fully open position in which the aperture is exposed to enable pouring liquid through the aperture;

the base plate being downwardly moveable relative to the top plate when moved from the sealed position to the intermediate position;

the base plate and top plate being: (i) translatable together relative to the can end from the intermediate position to the fully open position and (ii) translatable together relative to the can end from the fully open position to the intermediate position;

the base plate being upwardly moveable into engagement with the center panel from the intermediate position into a resealed position forming at least one of a bore seal and a flange seal;

wherein the bead is configured to engage with a rim of the aperture when the base plate is moved into the resealed position to thereby provide an audible “click.”

2. The re-sealable can end combination of claim 1 , wherein the base plate further includes a wing, adapted to ride on a cam surface to allow relative movement between the base plate and the top plate to enable venting.

3. The re-sealable can end combination of claim 1 , wherein the base plate includes one or more protrusions that enhance the inclination of the base plate upon rotation of the top plate relative to the base plate to enable venting.

4. The re-sealable can end combination of claim 1 , wherein in the closed position, the base plate includes a continuous flange for forming the face seal with the underside of the center panel, and a continuous upright ring for forming the bore seal with a lip of the aperture.

5. The re-sealable can end combination of claim 1 , wherein the top plate comprises a tab plate articulated by a living hinge.

6. The re-sealable can end combination of claim 5 wherein the living hinge is formed by a v-groove formed between the tab plate and an anchor plate, whereby lifting of the tab plate causes the sides defined by the v-groove to contact, and lifting forces applied to the tab plate are transmitted to the anchor plate and thereafter transmitted to the base plate.

7. The re-sealable can end combination of claim 1 , wherein the base plate includes at least one vent groove, adapted to define a flow path between the base plate and the top plate during venting.

8. The re-sealable can end combination of claim 1 , wherein the top plate includes at least one vent slot, adapted to define a flow path through the top plate during venting.

9. The re-sealable can end combination of claim 1 , wherein the base plate includes a rivet that couples the top plate and bottom plate together.

10. The re-sealable can end combination of claim 9 , wherein the rivet is hidden from view by a cover.

11. The re-sealable can end combination of claim 1 , wherein one of the top plate and the bottom plate includes at least one post that is insertable into an aperture formed in the other of the top plate and the bottom plate to prevent rotation of the top plate relative to the base plate.

12. The re-sealable can end combination of claim 1 , wherein (i) the top plate includes a tab having at least one downward extending protrusion, (ii) the center panel includes at least one recess, and (iii) the protrusion of the tab is adapted to fit into the recess of the center panel.

13. The re-sealable can end combination of claim 1 , wherein the center panel includes embosses to provide an indication to a user that the closure is in proper position for reclosing.

14. The re-sealable can end combination of claim 1 , wherein the closure includes a tamper evidence structure.

15. The re-sealable can end combination of claim 14 , wherein the tamper evidence structure includes a rivet that engages a hole on a tab of the top plate upon application, the tab being removable from the rivet upon initial opening.

16. The can end combination of claim 1 , wherein (i) the top plate comprises a cover plate and an anchor plate, and (ii) the cover plate is rigid relative to the anchor plate to facilitate flexing of the anchor plate during the opening process.

17. The can end combination of claim 1 wherein a downward force for opening is directly applied by a user.

18. The can end combination of claim 1 wherein a downward force for opening is by lever action of a tab of the top plate.
