LEVER-OFF TAMPER-INDICATING COMPOSITE CLOSURE

摘要

LEVER-OFF TAMPERINDICATING COMPOSITE CLOSURE A closure particularly intended for sealing containers having products packed therein under high vacuum wherein the vacuum retains the closure in place and a very high lifting or prying force is required to unseat the closure from the container to effect the removal thereof. The closure is provided with a supporting band which is interlocked with the shall of the closure and which supporting band has integrally formed as a part thereof a lever which is engageable with a shoulder on an associated container to effect the necessary lifting or prying action. The lever and associated supporting band are preferably injection molded of plastic material and may either be mechanically interlocked with the closure shell or molded in situ relative thereto. There are also suitable tamper indicating means. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
