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.

A spray mechanism for an aerosol product having at least a spray liquid and a spraying gas stored in a container, said spray mechanism comprising: a spray hole formed in said control member; a nozzle having a nozzle opening, said nozzle being provided in the container for supplying the aerosol product to said control member; a control part for selectively supplying the spray liquid from said nozzle opening to said control member; a regulator mechanism unit communicating with the nozzle opening and the spray hole, the regulator mechanism unit comprises a chamber formed at a front end of the nozzle in said control member, a sliding member provided slidably in the chamber, and thrusting means for thrusting the sliding member always toward the nozzle, the chamber including an opening formed at the front end of the nozzle so as to communicate with the nozzle opening, a communicating part to communicate with the chamber opening, and a connection hole disposed between the chamber and the chamber opening for communicating therebetween, the sliding member includes a partition wall disposed in the communicating part, and a shielding part disposed in the chamber opening and connected to the partition wall to be movable together with the partition wall, and wherein the sliding member slides in a direction resisting the thrusting force of the thrusting means by receiving first and second pressures greater than the thrusting force of the thrusting means by the spray liquid and gas released from the nozzle opening, wherein the shielding part shields and selectively closes the connection hole from the nozzle side along with the sliding motion of the sliding member in the direction resisting the thrusting force of the thrusting means, the partition wall slidably contacts with an inner circumference of the communicating part and communicates with the chamber opening in the communicating part, thereby forming a pool for temporarily storing the aerosol product flowing in from the chamber opening; and means for communicating between the pool and the spray hole, wherein the aerosol product is reserved in the pool until raised to a predetermined constant pressure maintained throughout dispensing into the spray hole through said means for communicating.
