摘要:
A biasing hinge is disclosed which is made up of a first hinge member and a second hinge member integrally hinged together along a curved line. The hinge members are shaped so that when one hinge member is swung relative to the other, the members are resiliently deformed or stressed and energy is stored in said hinge members. This stored energy will bias the hinge members to swing to an open or a closed position depending on which position is nearest said hinge member at a particular time. The hinge can be molded with the hinge members having the desired shape to provide the necessary stresses to provide the desired biasing. The hinge can also be molded as an integral part of a cap or closure.

A dual-durometer integral synthetic resin hinge joins two relatively rigid synthetic resin sections. The hinge comprises a first ply of the same composition and hardness as the rigid panels and an overlying second ply of relatively softer synthetic resin material. The first ply of the hinge is scored to provide a fracture line adjacent the hinge axis.

An integral snap hinge of plastic material is intended to be used, e.g., for container closures or vacuum formed packages. At least two flexible joints extending in the direction of the main geometric axis are provided between these two hinge members. At least one of these flexible joints is constituted by a connecting element, which is flexibly linked to the hinge members by film hinges. The film hinges diverge so that the connecting element widens along the main geometric axis. The large or small ends of two connecting elements may face each other. The snap action is due to the fact that components of the snap hinge are resilient. The spring action may be performed by the connecting elements and/or by walls of the hinge members.

A plastic hinge integrally interconnecting two plastic container sections having end walls, comprising an intermediate portion, and two reduced thickness webs respectively integrally interconnecting the intermediate portion with the end walls so that the end walls and the intermediate portion define an inverted U-shape, and wherein the end walls and the hinge together define a container end wall when the end walls are swung into a substantially common plane with the intermediate portion.

A snap-hinge in which two hinge members are hinged together about a first hinge line. A resilient connecting link is joined at one end integrally to one of the hinge members at a second hinge line and is hinged at the other end to the other hinge member at a third hinge line. The connecting link is capable either of compression or .[.of expansion.]. .Iadd.deformation .Iaddend.as between its two ends, and tends to maintain the hinge members in a given angular relationship, and to return the hinge members to that relationship if they depart from it.

1,063,156. Hinging lids. DE LUXE READING CORPORATION. Feb. 15, 1966 [May 24, 1965], No. 6473/66. Heading B8P. A hinge joining two box parts comprises a tongue (17), Fig. 4 (not shown), integral with one box part and joined to it along a flexible area (18) defining the hinge axis, outwardly extending wings (21) integral with the tongue, a pair of slots (23) in the second box part to receive said wings, each wing having a hooked end (22) that engages a slot margin to hold the tongue flat against the area (24) between the slots, said tongue and the area between the slots being resilient so that the tongue may be forced over a wedge-shaped boss (25) on the said area between the slots to lock the parts together. The box may comprise a polypropylene base portion on which the flexible hinge axis may be formed and a clear plastics cover portion.
