Abstract: In consumer-market containers for beverages or other contents under pressure, the cap provides a gas-tight seal by way of two mechanisms that work interdependently. The first is a pressure grip configured to grip the outside wall of the container. The second is twist threads, or some other second attachment structure, that urges the inside of the cap (or, typically, a cap liner disposed thereon) against the rim of the container. Release of pressurized gases when the container is first opened can be by way of release vents in the cap, or via the bottom of the cap through the twist thread area. In the latter case, particular configurations of the pressure grip are relied on to establish the gas escape path.

This ensures venting of the volume of the container with a relatively weak torque.

Abstract: A cap for use with bottled water dispensing systems. The cap includes a main cap and a liner. The main cap has an opening which receives and seals against a probe. The liner is gripped between the main cap and the bottle neck and has a outside part and an inner movable part. The inner movable part is separated from the outer part by perforations and is connected to the outer part by a large connecting section, which serves as a hinge, and small connecting sections, which serve as frangible ties. When the bottle is lowered onto the dispensing system, the probe enters into the opening in the main cap, breaks the frangible ties, and pushes the inner movable part open like a flap. The liner, at the location of the large connecting section, is resilient such that the inner movable part tends to close when the bottle is removed from the dispensing system.

Abstract: A composite closure includes a band and an insert disk. A contact surface urges downwardly against the disk even while the band moves longitudinally relative to the disk or container. The closure has a fully tightened position in which the band's ring contacts the disk's annular channel, a loose position in which the ring is spaced apart from the annular channel, and an intermediate tightened position in which the ring is spaced apart from the disk and the contact surface urges against the curl. Another composite closure includes plural fins or gussets. The fins or gussets engage the peripheral curl of the insert disk to secure the band to the disk, which provides a resistance to initial unscrewing of the band. The disengagement torque required to disengage the curl from the fins may enable the closure to function as a one-piece closure.

Abstract: The present development is for a closure which provides a means for maintaining an effective pressure against a peelable seal affixed to a container lip as the sealed container is exposed to relatively high temperature and pressure conditions. The closure includes a liner which abuts a surface of the seal so as to sandwich the seal between the liner and the container lip. The resilient liner and inner foil seal are positioned above a retaining structure and function such that the peelable seal will not rotate relative to a container rim upon engaging the container rim as the closure is rotationally applied. This functions to inhibit torque transmission from the closure to the inner seal or reseal structure and further inhibits imperfections in the container rim from scraping or otherwise damaging the inner seal.
