ABSTRACT:
A tamperproof closure for a bottle or other container having a neck portion with an external rib comprises a cap body of flexible, resilient material. This cap body includes an annular rim and a pair of skirts depending respectively from the inboard and outboard edges of this rim. The outboard skirt is provided with an internal rib that is adapted for lockable coaction with the bottle neck rib; and a circular top panel is connected to the inboard skirt to cooperate with the inboard skirt in defining a recess for receiving a cap-mounting tool. In accordance with the invention, the rim and its connection with the skirts cooperate to define a resilient hinge section.
