Abstract
This disclosure relates to a closure for containers primarily of the tumbler and carafe types and wherein the containers are formed of glass or glass-like materials. The closure is particularly identifiable by a downward and radial extension of the normal sealing ring to define a lug structure which interlocks with the exterior finish of the container and serves to retain the closure in place, both initially and upon reclosing. If desired, a shrink band or tape may add to the initial holding of the closure in place. Advantageously only the gasket material of the sealing ring is engaged with the finish of the container. The closure is distortable by diametrically squeezing the skirt thereof so as to break the initial seal in the event the product is vacuum packed.
Claims7
A closure for tumbler-like containers, said closure comprising a cap-like body including an end panel having a depending skirt defining in conjunction with said end panel a corner, and a sealing ring seated in said corner, said closure being characterized in that said sealing ring extends axially along a portion of said skirt and includes radially inwardly directed lug means for interlocking engagement with a container external finish, said cap-like body being formed of a resilient flexible metal, said sealing ring being formed of a resilient gasket material, and said skirt extending axially beyond said sealing ring in a direction away from said end panel and in radially outwardly spaced relation relative to said lug means and forming means for facilitating distortion of said sealing ring to break a seal between said sealing ring and an intended container.
