Abstract
Disclosed are self-sealing actuators and pumps for distributing fluids such as personal care products. The actuator can include a nozzle having an outlet that is opens and closes via movement of a plug. A limit rod is configured to engage with the plug and upon actuation the assembly opens a passage for the fluid to flow through an inner channel of the limit rod and to the outlet. Upon de-actuation, the assembly closes the passage sealing the fluid within a closed environment to prevent degradation and caking. Actuators and pumps as described protect the performance of active ingredients within the fluid and prevent the nozzle and outlet from blocking with dried or caked fluid.
Claims21
A self-sealing pressing and discharging actuator, which is fixedly connected to a pump body assembly and comprises a use state as a directional reference, the actuator comprising:
- an actuator body with a discharge cavity inside;
- a nozzle connecting the discharge cavity with an external atmosphere is connected to a side end surface of the actuator body;
- a plug positioned in the discharge cavity,
- wherein an end of the pump body assembly is connected to a limit rod, a central axis of which is perpendicular to a central axis of the plug,
- wherein the limit rod is in communication with an inside of the pump body assembly and an inside of the nozzle,
- wherein an end of the limit rod is slidingly connected to a tapered surface of plug enabling the plug to elastically stretch and slide along an axial direction of the nozzle, and
- wherein the plug has an avoidance state for opening the nozzle and a blocking state for closing the nozzle.
