PURPOSE: To reduce or completely prevent the useless consumption of the propellant of a pressurized container by disturbing the use in the inadequate position of a pressure dispenser. CONSTITUTION: A push button 4 has a collar 5 adapted to be fixed to the pressurized container 1, a spray nozzle 7 and an internal duct system 8 capable of connecting the outlet of a valve stem 3 to this spray nozzle 7. This internal duct system 8 has a hermetic sealing means F which is capable of closing a passage 15 communicating with the spray nozzle 7 when the angle formed by the axis A of the pressurized container and a vertical line exceeds a prescribed value γ and corresponds to an inadequate position. This hermetic sealing means F may be opened when the angle again restores the prescribed value γand corresponds to the adequate position. |
