    摘要： A container includes an airless dispenser for a cosmetic product. The container includes a hollow vessel body defining a sealed receptacle for containing a cosmetic product and a base. A dispensing head mounts at one end of the container and communicates with the receptacle for dispensing the cosmetic product. An actuator is associated with the dispensing head and configured to be operable to cause a pressure drop inside the receptacle. An outlet nozzle allows dispensing a desired quantity of cosmetic product when the actuator is operated. A plunger slidably and sealably mounts in the receptacle and is pushed from a spaced-out position towards a closer position relative to the outlet nozzle due to the pressure drop generated by operating the actuator. The hollow vessel body is made of glass, is substantially cylindrical, and defines a substantially constant cross-section through the axial segment in which the plunger is slidable.

    摘要： An all-plastic emulsion pump, includes a body, threads, pressing head, main column, suction tube, plastic spring, pull rod, stopper, lock cover, first and second one-way valve devices made of plastic material. A communication port is between the plastic spring and the main column. The pull rod is in the plastic spring. The stopper is connected to the pull rod upper end. When the plastic spring is pressed, there is a gap between the pull rod and the side wall of the communication port. When the plastic spring pops up, the stopper blocks the communication port. The first one-way valve device is between the pressing head and the main column to supply the emulsion to the pressing head. The second one-way valve device is between the plastic spring and the inlet of the body to supply the emulsion from the inlet of the body into the plastic spring.
