摘要

A unitary snap hinge made of plastic with two hinge parts which are connected with each other by means of a main joint. A flexible connecting piece is connected with the hinge parts by means of secondary joints, whereby the secondary joints have a distance from the main joint transverse to the joint axis and that the joints are designed as film joints. The hinge parts have the tendency to snap into the one or other end position from a position of an unsteady balance within their own pivot range. The snap hinge is a separate structural element. The one hinge part supports a locking element for a removal opening, the other hinge part supports at least one adapter piece with arresting elements. Thereby, the snap hinge can be mounted on a container or on the locking piece of the same. A snap hinge or other hinge made of plastic and which is part of a lock may have tearable parts on its foldable hinge part which during the first time closing of the lock are fixedly connected with the lower part thereof and are torn off during the first time opening.
