ABSTRACT:
A closure for a rigid or deformable container. The contents of the container are protected by a seal. The closure has a bottom part and a cap fixed thereon by a hinge. The lower part is closed by a cover face, through which only a pouring spout extends. A tear-off element is positioned on an underside of the cap in such a way that it extends through the pouring spout as far as the seal located below it. The tear-off element is in active contact with the seal, for example, it is bonded or glued to it. At the time of a first opening, the tear-off element pulls the seal upwards, which is simultaneously broken by a cutting element below the pouring spout. Such closures are structurally simple in their manufacture as well as in operation and can be attached to various types of containers.
