Abstract
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.
Claims9
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;
- and
- the 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.

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;
- and
- the resilient member adapted to:
- C) yield to downward pressure to allow a 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.
