ABSTRACT:
A container wall is disclosed having vent means in it for forming an opening in the container wall by digital force to release the pressure in a container which includes such wall. The force required to actuate the pressure release is not significantly affected by the internal pressure in the container due to the particular construction of the container wall as including two outwardly projecting hollow embossments separated by an inwardly projecting hollow rib with a score line across the rib near its middle. Each embossment has a top wall and a side wall therearound connecting the top wall to the adjacent portion of the container wall and with the side wall at both ends of the rib being generally transverse to the longitudinal axis of the rib. The apex of the rib is generally coplanar with the general plane of the container wall adjacent to the embossment and the side wall of each embossment is preferably thinner than the material in the adjacent container wall.
