Abstract
Abstract 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.

Claim 2
Dependent Claim
50 words
A unitary snap hinge made of plastic for closing a container adapted for simple molding and providing freedom of design of a locking member and container comprising: a snap hinge means for closing a container wherein the snap hinge means is separate from an associated container having a locking means.
Claim 3
Dependent Claim
64 words
A unitary snap hinge in accordance with claim 1 wherein the snap hinge means comprises two hinge parts connected to each other by a main joint, one of the hinge parts supporting a locking element for a removal opening of a container and the other hinge part supporting at least one plug part for mounting on a container or a locking piece associated therewith.
Claim 4
Dependent Claim
50 words
A unitary snap hinge in accordance with claim 2 further comprising an originality safety having at least one tearable part (174, 188, 194) provided on the snap hinge means which, after the first time closing the snap hinge means, is fixedly connected with a locking piece associated with the container.
Claim 5
Dependent Claim
127 words
A unitary snap hinge in accordance with claim 2 wherein the container is a container for longitudinally extending test carriers comprising: a longitudinally extending container body for receiving the test carriers; a locking means for locking the container body in a moisture proof manner; the container body and the locking means are injection molded parts; the container body has a flattened cross section in a plane transverse to its longitudinal direction deviating from the circular shape; the cross section of said removal opening is considerably smaller than the cross section of the container body; the container bottom encompasses a bottom element being separate from the remainder of the container bottom and moisture proof connected therewith; and the container body encompasses a chamber for receiving a drying substance.
Claim 6
Dependent Claim
156 words
A unitary snap hinge made of plastic comprising: (a) two hinge parts connected to each other by a main joint; (b) at least one flexible connecting piece connected with the two hinge parts by means of secondary joints; (c) the secondary joints each being distanced from the main joint transversely to the joint axis; (d) the joints are shaped in form of film hinges so that the hinge parts have a tendency to snap into one of the end positions from a position of an unstable balance which is located within its own pivot range; comprising the following features: (e) the snap hinge (1,1',1") is a separate structural part; (f) one of the hinge parts (4) of this structural part supports a locking element (32) for a removal opening of a container; (g) the other hinge part (2) supports at least one plug part with arrest element(s) for mounting on the container or its locking piece.
Claim 7
Dependent Claim
156 words
A unitary snap hinge made of plastic comprising: (a) two hinge parts connected to each other by a main joint; (b) at least one flexible connecting piece connected with the two hinge parts by means of secondary joints; (c) the secondary joints each being distanced from the main joint transversely to the joint axis; (d) the joints are shaped in form of film hinges so that the hinge parts have a tendency to snap into one of the end positions from a position of an unstable balance which is located within its own pivot range; comprising the following features: (e) the snap hinge (1,1',1") is a separate structural part; (f) one of the hinge parts (4) of this structural part supports a locking element (32) for a removal opening of a container; (g) the other hinge part (2) supports at least one plug part with arrest element(s) for mounting on the container or its locking piece.
