ABSTRACT:
A sealed container provides with a plug valve which employs a heat responsive band having one end attached to the side of the plug which is on the outer side of the plug when the plug is positioned in the container wall. The other end of the band extends around the edge of the plug holding the edge away from a valve opening in the wall of the container. This inner end of the band is connected through a wire to a fusable pin centrally positioned on the inner side of the plug. At the desired time, the fuse melts releasing the wire and the ban shrinks or retracks, releasing the edge of the valve member allowing it to seal against the container wall.
