ABSTRACT:
A self-venting container includes a top section and a bottom section. The top and bottom sections have adjoining side walls. The side walls are formed of a material which exhibits an elongation percentage greater than 100%. The configuration of the container is such that a cantilever-type movement of the side walls occurs when the walls are subjected to excessive pressure on their interior surfaces, resulting in a gap being formed between the top and bottom sections mainly along the side walls. The gap permits the release of excess pressure from within the container.
