Abstract

A closure sealingly engages with a container having a generally annular neck having a top edge and inner and outer surfaces and defining a container opening. The closure comprises a generally circular top wall having opposed inner and outer surfaces. A generally annular skirt extends downwardly from the inner surface of the top wall. A plurality of annular seal members, extending downwardly from and integral with the inner surface of the top wall, includes at least a plug seal that engages with the inner surface of the neck to create a first seal therebetween, a V-ring seal that engages with the top edge of the neck to create a second seal therebetween, and a flexible seal that engages with the top edge of the neck to create a third seal therebetween.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application No. 60 / 551,125, filed Mar. 8, 2004, with the same title.BACKGROUND OF THE INVENTION [0002] This invention generally relates to closures for containers and, more particularly, to caps that seal containers without the use of a separate liner or O-ring seal. [0003] Caps having separate liners or O-ring seals are generally known. The liners and O-rings in these types of caps are generally located on an inner side of a top wall of the cap. These caps generally operate by compressing the liners or O-ring seals between a top edge of a neck of the container and the top wall of the cap. [0004] Caps having flexible or rigid flanges that extend from an inner top wall of the cap to seal a mouth of a bottle when the flexible seal is brought into contact with the surface of the bottle adjacent the neck are generally known. Specifically, caps having rigid plug seals, rigid V-ri...
