Title: Closure with snap type hinge
Inventor: FILLMORE WILLIAM E
IPC: B65D43/16
Filed: 1988-09-22
Abstract: A closure (10) with a snap type hinge cap comprising a first part (11) adapted to interengage with the open neck of a container and a second part (12) forming a cap. Each of the first (11) and second (12) parts comprises a base wall (14) and a peripheral skirt (15). A pair of hinges (30) extends between the skirt (15) of the first part and the skirt (22) of the second part to hinge the parts about a hinge line. A short strap (36) connects the skirt of the first part and the skirt of the second part circumferentially between the hinges (30). The short strap (36) is axially rigid and has its ends hinged to the skirt of the first (11) part and the skirt of the second (12) part, respectively. The radial length of the strap is less than the length of the arc through which the second cap part is guided for movement by the hinges to and from open and closed positions relative to the first part. The portion of the skirt of the second part to which the strap is connected is capable of flexing. The strap (36) causes the flexing skirt of the second part to deflect while rotating between open and closed positions by pulling the skirt against its normal path. The reaction of the skirt to this pulling action is to tend to force the second part to remain open, or to tend to close the second part after sufficient rotation is made in the closing motion.
