ABSTRACT:
A closure having at least two layers adapted to be fixed to the end of a container to close the same the inner layer of the closure being scored on its inside as well as its outside surface in a manner to permit rupturing of the layer between the score lines when a force acts upon the outer layer to form a shouldered removed closure portion receiving ledge with which the removed portion will mate upon reclosing the container. In an embodiment, enclosure is crimped to the end of the container. In another embodiment there is provided between layers a pliable film, e.g., aluminum foil of size sufficient to extend over the end of the container so that when the removed portion is replaced the foil can be used to substantially seal the replaced portion to the end of the container and to retain it there. Since the sealing surface is broken when the container is opened, any tampering with the container will be readily observable.
