ABSTRACT:
A container comprising a wall structure defining an opening and an outwardly projecting bead extending peripherally about the opening is disclosed. A plurality of outwardly projecting vent ribs are provided on the bead. A closure which includes a cover member having a downwardly extending skirt is provided for sealing the container. The downwardly extending skirt has an inner peripheral surface which includes a curved member, for contacting the bead and the plurality of vent ribs, and also a tapered member extending downwardly from the curved member. Upon attachment of the cap to the container, the plurality of vent ribs allow for pressure to be released from the container over the bead and about the plurality of vent ribs, while allowing a sealing engagement of the cap with the closure to resume after relief of the pressure from the container.
