Title: Molded gasket press-on closure

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.
