An apparatus for closing an opening created by a removal of a breakable seal on a liquid container includes a stopper configured to overlap or cover the opening, an elongated arm having an end attached to the stopper for exerting a force on the stopper against the opening, and a flexible bridge having two ends which are affixed on the opposite sides of the wall of the container. A connection line has a first end secured to the stopper and a second end secured to the bridge. The opening is opened by applying force towards a middle of the bridge at the two ends and enabling the bridge to pull the stopper away from the opening via the connection line.

What is claimed is: 1. An apparatus for closing an opening created by a removal of a breakable seal on a liquid container, comprising: a stopper provided inside the container and configured to cover the opening; an elongated arm having a first end attached to said stopper for exerting a force on said stopper against the opening; a flexible bridge having two ends which are affixed on opposite sides of the container; and a connection line having a first end secured to said stopper and a second end secured to said bridge; wherein the opening is opened by applying force towards a middle of said bridge at said two ends and enabling said bridge to pull said stopper away from the opening via said connection line. 2. The apparatus as defined in claim 1, wherein said stopper is configured to be approximately the same shape as the opening. 3. The apparatus as defined in claim 1, wherein said stopper is formed from a flexible impermeable material. 4. The apparatus as defined in claim 1, wherein said stopper includes a gasket for providing a seal around the opening when said stopper is pressed against the opening. 5. The apparatus as defined in claim 1, wherein said arm further includes a second end fixedly attached proximate one of said two ends, said arm being configured and positioned to be in tension toward the opening. 6. The apparatus as defined in claim 5, wherein a thickness of said arm narrows toward said first end. 7. The apparatus as defined in claim 1, wherein said bridge comprises a pad formed at each of said two ends, and said force is applied at said pads to enable said bridge to pull said stopper away from the opening. 8. The apparatus as defined in claim 1, wherein said two ends of said bridge are affixed to the container by a post projecting from said opposite sides of said container. 9. The apparatus as defined in claim 1, wherein said connection line is formed from plastic or nylon. 10. The apparatus as defined in claim 1, wherein said connection line terminates in a ball at said first and second ends, and said balls are each received in an anchor fixed to said stopper and said bridge. 11. The apparatus as defined in claim 1, wherein said bridge comprises a hinged portion at approximately at said middle of said bridge, said hinged portion being configured and constructed to bend away from said stopper when said force is applied to said two ends. 12. The apparatus as defined in claim 11 wherein said second end of said connection line is secured proximate said hinged portion. 13. The apparatus as defined in claim 11, wherein said bridge comprises a slit extending transversely to the longitudinal direction at said hinged portion. 14. The apparatus as defined in claim 1, wherein said bridge comprises an elliptical ring, and said two ends are located approximate opposite two points on said ring. 15. The apparatus as defined in claim 14, wherein said bridge further comprises: a pair of braces located at opposite two points on said ring; and a through hole formed on each of said braces and overlapping each other; wherein said connection line is routed through said holes so that when said force is applied at said two ends of said bridge, the holes separate from each other and pull said connection line and said stopper away from the opening. 16. The apparatus as defined in claim 1, wherein the liquid container is a metal can. 17. A liquid container having an apparatus for sealing and unsealing an opening created by a removal of a breakable seal on the container, comprising: a stopper provided inside the container and configured to overlap the opening; an elongated arm having a first end attached to said stopper for exerting a force on said stopper against the opening; a flexible bridge having two ends which are affixed on opposite sides of the container; and a connection line having a first end secured to said stopper and a second end secured to said bridge; wherein the opening is opened by applying an inward force on the container proximate said two ends and enabling said bridge to pull said stopper away from the opening via said connection line. 18. A beverage can having a self-closing stopper for an opening of the can, said can comprising: a top having a breakable seal for creating the opening when said seal is removed; a stopper provided inside the can and configured to overlap the opening; an elongated arm having a stationary first end and a second end attached to said stopper for exerting a force on said stopper against the opening; a flexible bridge having two ends which are affixed on opposite side of the can; and a connection line having a first end secured to said stopper and a second end secured to said bridge; wherein the opening is closed by a force exerted on said stopper against the opening by said arm when said seal is removed, and opened by applying an inward force on the can proximate said two ends and enabling said bridge to pull said stopper away from the opening via said connection line. 19. The can as defined in claim 18, further comprising a post projecting inwardly from said opposite side for affixing said two ends of said bridge. 20. The can as defined in claim 18, wherein said bridge comprises; an elliptical ring, said two ends being located approximate opposite two points on said ring; a pair of braces located at opposite two points on said ring; and a through hole formed on each of said braces and overlapping each other; wherein said connection line is routed through said holes so that when said force is applied on the can, the holes separate from each other and pull said connection line and said stopper away from the opening.
