Next, the operation of the pump dispenser according to the present invention configured as described above and the effects thereof will be described.

First, as shown in FIG. 2, in the initial state of the pump dispenser 200, the hollow piston shaft 240 is raised together with the push head 300 by the elastic support force of the coil spring 242, and the cylinder The contents are sucked and stored in the pressure chamber 221 of 220.

In this state, the user presses down the head-body 310 of the pushhead 300; As shown in FIG. 7, the hollow piston shaft 240 descends while overcoming the elastic bearing force of the coil spring 242 (see arrow A direction in FIG. 7). Therefore, the contents filled in the pressure chamber 221 of the cylinder 220 is the piston shaft 240 → the ejection flow path 311 of the head-body 310 → the ejection hole 331 → the outlet 343 of the brush member 340 Are blown out through the air. At this time, the check valve 230 disposed in the inlet 222 of the cylinder 220 is in close contact with the valve seat 223 as the internal pressure of the pressure chamber 221 increases, and thus the pressure chamber 221 and the container 100 are closed. ) Block communication with the inside. The closing operation of the check valve 230 is made from the moment the piston shaft 240 descends. That is, the contents filled in the pressure chamber at the moment when the piston shaft 240 is lowered together with the push head 300 pressurizes the check valve 230 downwards, so that the inlet 222 of the cylinder 220 is firmly secured. It is closed so that there is no pressure loss during the pumping operation.

And when the user releases the pushhead 300; The push head 300 is instantaneously raised together with the piston shaft 240 by the restoring force of the coil spring 242, thereby applying a vacuum pressure to the pressure chamber 221 of the cylinder 220. That is, the piston shaft 240 is raised by the elastic restoring force of the coil spring 242 at the moment of releasing the push head 300, and the pressure chamber 221 is subjected to vacuum pressure so that the check valve 230 in the valve seat 223 is closed. Slightly lifted, this causes the suction port 222 to be opened so that a part of the contents in the pump container 100 is sucked into the pressure chamber 221 through the suction tube 224. In addition, the inside of the pump container 100 in which some of the contents are removed is filled with the external air by the volume through the air hole 225, so that the pump dispenser 200 is maintained at an initial state.

Meanwhile, the contents are finally ejected through the brush member 340 according to the push head 300 pressing operation, so that the user directly applies or cleans the contents to the skin through the brush member 340 without using a palm (cleansing). can do. At this time, since the front of the brush member 340 is provided with a soft massage-protrusion 342, it is possible to apply the contents evenly while pressing the massage like a skin. As a result, the contents can be evenly applied or washed (cleansing) while pressing the skin as if massaged according to the type of contents.

The present invention can be widely used in the field of "pump dispenser with a pushhead" which inhales / pumps and discharges the fluid (contents) contained in a container by repeatedly pressing the pushhead.
