Abstract
Abstract A tamper indicating closure for a container has a center section provided with a ring which may be pulled to open the container. The pull out center section forms part of an insert which is held in position by a cap base. The insert is interposed between the cap base and the neck of the container so as to form a seal between the cap base and the container. The insert can be formed of a softer more easily torn material than the cap base. The cap base can also serve as a pour nozzle for easy pouring, and also will cooperate with the cap lid to obtain a secured closure of the container once the center section of the insert is removed.
