Abstract
A container containing a liquid and vaporizing gas to be sprayed is provided with a control member having a spray hole, and when the control member is manipulated, the liquid is sprayed by the gas pressure of the spraying gas. A sliding member is provided in the control member, and a pool is installed in the passage of the spray liquid and the vaporizing gas. When the gas pressure in the pool is raised to a specified pressure, the sliding member works to close the passage, and when the gas pressure in the pool drops, the passage is opened, and the gas pressure is built up. As a result, the spray liquid and the gas are temporarily stored in the pool until raised to the specified internal pressure, and then sent into the spray hole, so that the spray liquid is always sprayed from the spray hole at a specific pressure, so that a specific spray state and atomization state may be always maintained.
