Abstract
A tamper indicating closure according to the present invention includes a top wall and a skirt depending from the top wall. A tamper indicating band is connected to the skirt along a frangible line. The tamper indicating band includes a ring and at least one tab, the at least one tab having a bi-stable geometric shape. In particular, the tab includes a pair of extending members angled toward one another and connected by a transverse member. The shape of the tab allows it to be molded in a downward orientation and later folded to a stable, upward orientation without reheating or otherwise resetting the tab.
Claims3
A method of producing a tamper indicating closure, the method comprising:
- (a) molding a closure including a top wall, a skirt, and a tamper indicating band, the tamper indicating band including a ring and a plurality of trapezoidal tabs each connected to the ring at a base, each tab having a transverse member and extending members, a maximum thickness of the transverse member being substantially equal to a maximum thickness of a tip of each extending member when said thickness are measured in the same direction, and each of the tabs having a trapezoidal hole therethrough, each of the plurality of tabs being molded in a downward orientation;
- and
- (b) folding the tabs to a stable inward and upward orientation.
