Title: Aerosol spraying mechanism
Inventor: KIWAMUI MIYAZAKI
IPC: B65D83/14
Filed: 1993-11-05
Abstract: A container (1) contains a liquid to be sprayed and the gas in the vapour state for the spraying and it is provided with a control device (2) having a spraying orifice (7). When the control device (2) is actuated, the liquid is sprayed under the effect of the pressure of the gas. A sliding element (5) is provided in the control device (2) and a reservoir (42b) is defined in the liquid and gas passage. When the pressure of the gas in the reservoir (42b) rises to a specified value, the sliding element (5) moves in order to close the passage and, when this pressure falls, the passage opens and the pressure of the gas rises again. The liquid and the gas are therefore stored temporarily in the reservoir (42b) until they reach the specified pressure and they are then sent to the orifice generating the spraying (7) such that the liquid is always sprayed at the orifice (7) at a specified pressure and such that a specified spraying and aerosol state can always be maintained.
