发明名称 Tear strip closure with improved tamper indication
摘要 Disclosed is a container and closure assembly including a container having a substantially circular opening and an outer wall containing an upper retention bead and a lower, regularly-outwardly extending security ring. The closure includes a one-piece plastic body having a top panel and an encircling skirt depending from the top panel so as to be integrally attached thereto. The skirt includes a groove for locking engagement with the retention bead to retain the closure on the container. A circumferential line of weakness in the skirt wall defines a removable tear strip having a movable free edge and which is removable from an upper portion of the skirt wall by fracturing the skirt wall along the upper line of weakness. A tear strip is weakened so as to form a plurality of circumferentially-spaced segments throughout the substantial entirety of its periphery. The segments are separable one from another in response to a prying or wedging force applied to the tear strip at the free edge thereof.
