  • Squeeze-off closure with tamper indicating band
    Patent number: 4228909
    Abstract: This disclosure relates to a closure assembly for containers, particularly glassware containers, wherein the closures may be readily removed even when the product is vacuum packed by the deformation of the cup-shaped body of the closure and the sealing ring through the application of a diametrically opposite squeezing pressure. Normally the deformation of the closure body is prevented by a removable tamper indicating ring which interlocks with the skirt of the closure body and which must be ruptured to effect the removal thereof. The closure may assume various configurations depending upon whether the container is to be reclosed and whether there is an internal vacuum. The closure construction permits a modified sealing surface finish on the glassware container.

  • Molded gasket press-on closure
    Patent number: 4227616
    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.
