发明名称 Tamper evident container seal with integral pull opener
摘要 A tamper evident container closure seal with an integral pull opener is constructed from one or more layers of frangible sheet material adhesively bonded to one or more layers of strengthening sheet material. The one or more strengthening layers each contain one or more duplicate void configurations that form a weak area in the multi layered seal only in the area of the void configuration. When a consumer forces a finger into the seal when bonded to the rim of a container the applied pressure forces the seal to break open and tear only in the weaker area of the void configuration while the peripheral portion of the seal remains bonded to the container rim. The broken open center portion of the seal then forms a pull tab that can be partially connected which allows the pull tab to be lifted back out and pulled from the container.
