Abstract:
1. A device for dispensing a fluid from a storage chamber of a container via at least one closeable discharge port to the outside, the device comprising: a pressure reservoir being separated from the storage chamber and containing a pressurized propellant; a discharge valve communicating with said pressure reservoir allowing discharge of propellant from said pressure reservoir upon activation; a pressure regulation mechanism communicating with said storage chamber and said discharge valve, said pressure regulation mechanism having an open position in which propellant is discharged via said discharge valve into said storage chamber and having a closed position in which there is no discharge of propellant into said storage chamber; said pressure regulation mechanism comprising a regulating assembly having a regulating element that is axially movable against said discharge valve for discharging propellant from said pressure reservoir; a biasing element for biasing said regulating element into the direction of said open position; an actuator member cooperating with said pressure regulation mechanism being accessible from outside the container and allowing transferring the pressure regulation mechanism from an inactive position in which no pressure regulation occurs into an activated position in which pressure regulation is activated; and a lock cooperating with said actuator member so as to allow transferring the pressure regulation mechanism from an inactive position into an activated position but to prevent transferring the pressure regulation mechanism from an activated position into an inactive position; wherein said pressure regulation mechanism further comprises a valve housing inside which said actuator member is held rotatably; wherein said valve housing on a side facing away from said pressure reservoir further comprises a cavity which is sealed against said storage chamber in said inactive position, said cavity being ventilated to the outside in said activated position.
