ABSTRACT:
A transparent thermoformed thermoplastic blister has a product bubble which protrudes from a flange which is connected to a backing card. The bubble has an access opening which is selectably uncovered by a pivotable door hinged to the flange and to a hinge panel by parallel hinges, with the hinge panel hinged to the flange to define an over-center hinge arrangement. The lengths of the hinge panel and door, as well as the spring constants of the hinges may be selected to form a closure which will tend to remain opened once opened, or alternatively one which will automatically spring closed when finger pressure on the door is released. The closure may alternatively be formed in a clamshell package. The physical manipulation of the door is similar to the throwing of a light switch, and hence is readily apprehended by new users.
