ABSTRACT:
A pull tab of the type having a mounting ear which is rigidly secured to a container panel and wherein a major portion of the tab is hingedly connected to the mounting ear for pivoting to an operative position. The mounting ear is defined by a generally C-shaped lance or cut line and the tab is distinguished by having a child proof feature in the form of one or more interruptions of the lance or cut line with the interruption being selectively a full thickness portion of the tab body or a portion of the tab body having a score formed therein whereby the force necessary to effect a separation of the tab body from the mounting ear so that the tab body may hinge relative to the mounting ear may be selectively varied so as to control the force required to place the tab in a use condition, and thus permit the use of the tab to be restricted to persons other than children of a generally selected age.
