Patent ID: 8596476

Claim:
A non-reapplying plastic closure, comprising: a main body portion having a downwardly depending sidewall, said sidewall having an inner surface that is shaped to be applied over an unthreaded finish portion of a container having retention structure provided thereon; locking means provided at a lower end of said sidewall, said locking means being constructed and arranged to engage the retention structure of the container so as to make it difficult to remove said closure from the container after the closure has been applied to the container; and wherein said sidewall has a predetermined area of weakness defined therein, said predetermined area of weakness being constructed and arranged to rupture in the event that an attempt is made to remove the closure from the container, the predetermined area of weakness being located in a portion of the sidewall so that the closure will lack sufficient structural integrity to be successfully reapplied to the container in the event that the effort to remove the closure from the container is successful, and further wherein said predetermined area of weakness is defined by a portion of the sidewall that has a reduced thickness with respect to adjacent portions of the sidewall.
