Beschreibung
Zusammenfassung: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 ).
