ABSTRACT:
A tamper indicating seal for a dispensing closure that is secured to a container to discharge the contents thereof. Closure induces a depending skirt, and a planar top surface, with a cavity defined within the top surface. A spout is located within the cavity, and may be pivoted between a horizontal, closed position and a vertical, open position. The unique seal comprises a thin plastic tab, with frangible members depending below, to secure the tab to the upper surface of the spout in an overlying relationship. The frangible members are durable enough to form an effective seal, yet weak enough to fracture when the spout is pivoted toward its vertical position. The tab, when severed from the spout, is used as a proof of purchase indicator. The absence of the seal clearly indicates to the user that someone has attempted to gain access to the contents of the container.
