Abstract
A valve (20) is provided for sealing an evacuation port (16) in a port area (18) of a wall structure (12) of a container. The valve (20) comprises a casing (22) having a shell portion (30) which is deformable from an open condition, whereat the shell portion (30) forms a chamber (32) over the port area (18), and a closed condition, whereat the shell portion (30) contacts the port area (18). When the shell portion (30) is in its open condition, gas exits from the chamber (32) through gas-releasing holes (24) in the casing (22). When the shell portion (30) is deformed to its closed condition, a port-sealing adhesive (26) adheres to the port area (18) to thereby seal the evacuation port (16).
Claims11
A container, comprising;
- a wall structure and a valve, the wall structure defining a receptacle and an evacuation port in a port area of the wall structure, the valve comprising a casing having a shell portion which is deformable from an open condition, whereat the shell portion forms a chamber over the port area, and a closed condition, whereat the shell portion contacts the port area;
- gas releasing openings in the casing, through which gas exits from the chamber when the shell portion is in the opened condition;
- a supporting structure positioned between the casing and a wall structure;
- and a port-sealing adhesive adhering the shell portion to the port area when it is in the closed position, to thereby seal the evacuation portion;
- and
- wherein the casing of the valve is positioned entirely over the port area to form the chamber there over when the shell portion is in the open position.
