Abstract (en)
[origin: EP0066900A2] This disclosure relates to a tamper indicating ring (28) for a closure assembly (24, 62) for containers, particularly glassware containers, wherein the closures (26, 28) may be readily removed even when the product is vacuum packed by the deformation of the cup-shaped body (32) of the closure and the sealing ring (44) through the application of a diametrically opposite squeezing pressure. Normally the deformation of the closure body is prevented by the removable tamper indicating ring (28) which interlocks with the skirt (36) 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 (66) on the glassware container.
