Abstract

A plastic cap has one or more hinged flaps that cover openings in the cap as well as a stepped sealing ring against which the top of a plastic bottle seals. The sealing ring is stepped, much like the rows of seats in a circular stadium. This stepped arrangement permits the cap to be used with many different bottle rim diameters and automatically corrects any ovality of the bottle rim by forcing it to flex into a more circular shape as it engages the steps of the stepped ring.
