20090145902 | TAMPER-PROOF CLOSURE FOR A TUBE - A tamper-proof closure for a tube includes a tab which is placed at a distance to an end face of a neck of a tube. Connected to the neck by a perforate line is a membrane for sealing a discharge bore of the neck. The membrane has a neck-distal side which is formed in one piece with a ring defined by an outer diameter which is smaller than an inner diameter of the neck. The tab is connected to the membrane by a hinge by which the tab can be pulled upwards to allow the membrane to be yanked out from the neck by a user. | 06-11-2009 |
