Abstract: This invention provides a sectional bar system consisting of X-section bars and connecting elements preferably made up of pyramids. The advantages of the invention are a large variety of possible designs and high stability of the sectional bar system as well as easy and inexpensive production of the connecting elements.

Abstract: An originality guarantee for closures of containers, particularly bottles. It has a label (12) which, after it has been removed or damaged, indicates that the closure has been opened. The closure portions (4,6) which are to be moved apart when it is opened are provided with flat recesses for receiving the label (12). The recesses merge from one closure portion into the other or others and together have the external shape and size of the label. Such a label indicates that the closure has been opened when it is torn or cut through. The invention also prevents the possibility of the label being removed and glued on again. This purpose can be served by the said recess which makes it impossible for a user to engage beneath the label with a finger nail or a tool and to lift it away. Instead of a recess a horseshoe-shaped wall (22) can be provided which surrounds at least a portion of the label. It may be broken away so that the user has access to the label.

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.
