Abstract
A closure system adapted to closing off in leaktight manner a reservoir (50) of a dispenser device for dispensing a freeze-dried substance, said closure system being characterized in that it comprises a closure element (1) having a fixing portion (10) co-operating in leaktight manner with the reservoir (50), and a closure portion (11) comprising a radial diaphragm (11) provided with a slit (12), interference between said closure portion (11) and said reservoir (50) being zero or almost zero, so that the slit (12) can open to either side whenever pressure is exerted on the other side of said closure portion (11), said slit (12) being closed in leaktight manner in the absence of such pressure.
