Actuator for liquid ejection

An actuator for liquid ejection, which is adapted to be mounted on a container of the type that is filled therein with a pressurized fluid and having a valve spout, said actuator comprising:

• a fluid-introduction passage, which is adapted to be communicated with a valve spout of the container;
• a fluid-discharging passage intersecting with a distal end of said fluid-discharging passage, and forming an ejection spout at a tip portion thereof;
• an actuating rod coaxially disposed in said fluid-introduction passage, said actuating rod having a proximal end for effecting opening the valve spout of the container and a distal end portion thereof being projected into said fluid-discharging passage;
• an elastic rod-like member disposed in and along said fluid-discharging passage, a proximal end portion thereof being secured to the proximal end portion of said fluid-discharging passage, and a middle portion thereof comprising over the distal end portion of said actuating rod, said elastic rod-like member and said fluid-discharging passage being located within a body portion carried on said container means and held in position by said actuating rod, one end of said actuating rod being disposed within said container and spring means being disposed to extend between said body portion and said container to maintain said housing in spaced relationship from said container when in a deactuated position;
• a plug attached to the distal end portion of said elastic rod-like member and adapted to close said ejection spout formed at the tip portion of said fluid-discharging passage, said plug being forced to move backward to open the ejection spout as said elastic rod-like member is arched by a pushing movement of said actuating rod against the middle portion of said elastic rod-like member, thereby communicating said ejection spout with said fluid-discharging passage.
