    Abstract: A container, in particular a bottle, made of a plastic which can be elastically deformed. The container has a pipe for filling and removing the contents. The container has a part which can be folded in in its main part or in its shoulder section.

  • Patent number: 4403712
    Abstract: 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.
