ABSTRACT:
A closure accommodating internal pressure build-up in a container. The closure includes a cover, the top wall of which which is provided with a small orifice. A flexible plastic film lid or patch is sealed over the orifice by sealant such as adhesive or heat-seal. The patch may also be sealed by welding. The sealant may be pressure sensitive. When pressure within the container reaches a predetermined level, a small channel will form in the patch and gases will be released. The orifice may include pre-formed V-shaped venting notches in its top edge to direct gas-pressure.
