Abstract
Abstract The closing device is provided for a container in which a cap is put in position on one end of the container forming a neck. The cap comprises an encasing portion for the container and a portion including opening and closing means. A membrane is sealed to a portion forming the neck of the container. A perforation member is placed in the vicinity of the membrane and provided for folding back this membrane toward walls of the neck. Means are arranged such that the perforation member can occupy a first position for which it cannot act on the membrane and at least a second position for which the membrane is broken and folded back.
