Abstract (en)
The stopping means comprises an intermediate chamber (15) arranged at the free end of the neck (2) of a flask (1). This chamber is delimited at its upper part by an elastic membrane (14) mounted rotatably relative to the axis of the neck. At its lower part, it is limited by a fixed base (10) perforated with two inlet orifices (16) to the chamber. An outlet orifice (18) from the chamber (15) is arranged in the centre of the membrane (14) and a projection (17), located opposite the outlet orifice (18) on the base (10), closes the latter. The membrane (14) comprises protuberances (19) which penetrate partially into the inlet orifices (16) and close them off, producing locking of the device. Rotation of the membrane (14) by acting manually on the skirt (12) of the movable cap (6) gives rise to an elastic deformation of the membrane and releases the device, placing the inside of the flask and the chamber (15) in communication via the inlet orifices (16). By increasing the pressure beyond a specific value inside the flask, the membrane (14) is further deformed and the outlet orifice (18) is disengaged from the projection (17), the device then being in the open position. <IMAGE>
