Patent abstract
The present invention describes a container end closure which utilizes a material that is adapted to provide a visible indicator when the internal pressure of the contents increase to a predetermined level. In one embodiment, an interruption in a reinforcing bead incorporated in the end closure is deformed to visually notify a consumer of spoilage due to bacterial activity and to substantially prohibit the use of traditional can openers to access the spoiled contents within the container.
