ABSTRACT:
A tear-off safety closure is described in particular for ensuring authenticity and for additional sealing of a bottle-shaped container containing especially pharmaceuticals which is already closed by a disk-shaped or plug-shaped sealing element. The cap surface and the closed flange-shaped jacket of the closure enclose the sealing element and the rim of the container neck which has an outwardly projecting ridge. The closure has a tear-out part which can be detached to expose the surface of the sealing element, e.g., for piercing with a hypodermic needle. The jacket has retaining devices which are arranged on its inner surface at a distance from its lower edge and which engage under the lower edge of the ridge. The closure is produced from plastic in its entirety and so as to form one piece, in particular from thermoplastically deformable plastic such as polypropylene or polyamide.
