ROTARY CLOSURE WITH LINER FOR A CONTAINER

摘要

The invention concerns a rotary closure especially for medication bottles, which has a rotary cap, in which a liner that closes the opening is provided. The liner has at least two layers, which contact each other along a contact surface; the upper layer initially lies in the rotary cap and is joined to it at least in the central part of the face and the lower layer is firmly joined to the annular face of the opening and the liner has a weakening line (4). In order to achieve simple and clean opening, it is prescribed that the weakening line (4) is closed and leads around the central part (3) of the face and that in the area of the contact surface within the weakening line (4) joining of the two layers is strong and outside the weakening line (4) it is not present or only weak.
