Abstract:
In the dispensing device, preferably a double cartridge (1) having a stopper and a locking ring provided with bayonet connecting means, the stopper (7), the external surfaces of the cartridge outlets (4, 5), and the wall interior of the locking ring (6,) comprise mutually cooperating means (17, 26; 18, 27) for pressing the stopper into the outlets or pulling it out from the outlets as the locking ring is rotated. On one hand, this allows to obtain a tight closure, and on the other hand, it is very simple in this manner to pull out the tightly fitting stopper.
