An actuator for liquid ejection which is provided with a plug for closing the ejection spout disposed at the distal portion thereof. This actuator is capable of preventing a residual liquid which is left inside the actuator after an ejection operation from being contacted with an outer atmosphere, thereby preventing the denaturing or degradation of the liquid. Further, it is capable of preventing an ejection spout from being stopped up and of preventing a filmy cover or block to be made. This plug is mounted on an elastic rod-like member disposed in and along the liquid-discharging passage, and is adapted to be moved backward, thus opening the ejection spout as the elastic rod-like member is forced to bend by an actuating rod when the actuator is pushed downward.

An actuator for liquid ejection, which is adapted to be mounted on a container filling therein a pressurized fluid, and comprises: a fluid-introduction passage, which is adapted to be communicated with a valved spout of the container; a fluid-discharging passage intersecting with a distal end of said fluid-introduction passage, and forming a ejection spout at a tip portion thereof; an actuating rod coaxially disposed in said fluid-introduction passage, a proximal end thereof being adapted to press open the valved 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 crossing over the distal end portion of said actuating rod; a plug attached to the distal end portion of said actuating rod, 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 forced to be 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.
