Lock washer for a lock.

The utility model relates to a tension washer for a closure, in particular for a Screw cap for bottles.

The invention is based on the task . Round to produce a tension washer which, particularly in the case of a screw cap for bottles © ine tightly «seals the bottle opening» This is done; According to the invention achieved in that the middle part of the old clamping disk, which was provided with a plate-like hand, is pulled up over the edge of the disk. Before the screw cap is put on, the bottle opening is opened; the clamping washer put on » When tightening the

The tensioning lever as part of the invention can consist of an elastic plastic _# preferably polyethylene *

In the drawing is an embodiment of the Invention shown.

i screwdriver loaaes presses the bottom of the same first on the re-drawn middle part of the tensioning disc. This will result in further »tightening of the screw cap this middle part of the tensioning disc pressed down * so that the in open bottles * Neck protruding 3Je-He egg 3p * nnacheibe pressed apart and attach to the inside wall of the bottle neck cuddle up and use a "^ connection of the To give the opening "

Its preferred form of execution of the object the invention provides * that the raised part an upward tapering * through a plane Area- closed Kugelstromf forms *

The tensioning disk shown in the drawing represents only one embodiment which is intended to carve out the sedanks on which the invention is based. It is therefore irrelevant to the details of the example shown, since the same effect of the tensioning disc can also be achieved with a modified form ; if only the middle part of the tensioning pulley, which is provided with a »plate-like band, is pulled over the edge of the pulley nose ·
