A self-closing resealable can end for a beverage container that opens the top of the beverage container through downward pressure that causes a gate to move downward relative to the top panel. The gate is retained by a resilient member and when the downward pressure ceases, the gate is moved into proximity with the top panel. Pressure from the carbonation presses the gate against a lip and the gate bends to form an enhanced seal. Other variations are disclosed.

1. A self-closing resealable can end for a beverage container comprising: a top panel with an integrated gate contained as part of a folded seam with a weakened line that forms a closed perimeter surrounding the integrated gate;the integrated gate adapted to separate along the weakened line with the application of downward pressure to form: A) an opening along the entirety of the closed perimeter and; B) a separated gate distinct from the top panel; the integrated gate connected to a first portion of a resilient member with another portion of the resilient member connected to the top panel beyond the closed perimeter such that a separated gate is indirectly connected to the top panel through the resilient member; andthe resilient member adapted to: C) yield to downward pressure to allow the separated gate to move away from the top panel; and D) after the cessation of downward pressure, place the separated gate in sufficient proximity to the opening formed in the top panel such that gas pressure formed above a surface of a carbonated beverage placed within a beverage container using the self-closing resealable can end will press the separated gate into contact with the top panel with sufficient force to bend the separated gate for an enhanced seal. 2. The self-closing resealable can end of a beverage container of claim 1 wherein the self-closing resealable can end is connected to a generally cylindrical can body. 3. The self-closing resealable can end of a beverage container of claim 1 wherein a portion of the integrated gate extends above the top panel such that a user may press a portion of a lip against the separated gate to push the separated gate downward and create a fluid path through the opening. 4. The self-closing resealable can end of a beverage container of claim 3 wherein the integrated gate has a lip depression to assist in positioning the lip of a user. 5. The self-closing resealable can end of a beverage container of claim 1 wherein the weakened line is isolated from a top surface of the self-closing resealable can end so there are no exposed sharp can opening edges. 6. The self-closing resealable can end of a beverage container of claim 1 wherein a perimeter of the separated gate is curved and corresponds to curved portion of the top panel. 7. The self-closing resealable can end of a beverage container of claim 6 wherein a perimeter of the separated gate is concave and receives a convex lip of the top panel. 8. The self-closing resealable can end of a beverage container of claim 1 wherein the integrated gate is contained as part of a dual-fold seam formed into a stamped blank for a can end used in a process to make the top panel. 9. A self-closing resealable can end for a beverage container comprising: a top panel with an integrated gate surrounded by a weakened line that forms a closed perimeter surrounding the integrated gate;the integrated gate adapted to separate along the weakened line with the application of downward pressure to form:A) an opening along the entirety of the closed perimeter wherein the separated weakened line on the top panel is isolated from a top surface of the self-closing resealable can end so there are no exposed sharp can opening edges; and;B) a separated gate distinct from the top panel;the integrated gate connected to a first portion of a resilient member with another portion of the resilient member connected to the top panel beyond the closed perimeter such that the separated gate is indirectly connected to the top panel through the resilient member; andthe resilient member adapted to:C) yield to downward pressure to allow a separated gate to move away from the top panel; andD) after the cessation of downward pressure, place the separated gate in sufficient proximity to the opening formed in the top panel such that gas pressure formed above a surface of a carbonated beverage placed within a beverage container using the self-closing resealable can end will press the separated gate into contact with the top panel with sufficient force to bend the separated gate for an enhanced seal.
