Abstract:

A resealable container cap includes a skirt portion that is permanently attached to the container about a container opening. A plug portion, hinged to and received within the skirt portion, engages the container wall to seal the opening. A score line initially connects and provides a line of weakening between the skirt and plug portions. Initial removal of the plug portion from the skirt portion to open the container tears the connection along the score line leaving a clearly visible indication that the container has been previously opened.
