Patent attributes
A mold can form a one-piece container closure by injection molding. The closure may have a base portion that inwardly defines an opening centered about a base portion longitudinal axis and a hinged cap that is linked to the base portion by an outside hinge member. The hinge member may have two opposite ends that are respectively connected to the base portion and the cap, thus defining an elongated hinge member therebetween. A mold may include two parts which respectively define two internal cavities facing each other along a longitudinal axis of alignment that coincides with the base portion longitudinal axis. The two mold parts my be movable along the longitudinal axis of alignment between a closed position where they define together a mold jointing plane and an open position where they are spaced apart from each other for demolding the closure.
