Content exhaust pump

The present invention relates to a discharge pump that is mounted to the opening of the container so that the cosmetics contained in the container can be discharged out by a predetermined amount by the pumping operation, and more specifically, this is a utility model registration filed and registered by the applicant in advance. By improving the structure of the first valve, which is a valve-elastic elasticity of the arc, when the contents are discharged by the pumping operation of the pushbutton, the elastic pushbutton raising and lowering member, which is caused by the elastomeric pushbutton raising and lowering member, comes into contact with the contents and It prevents the deterioration of contents and improves the problem of disposing because it is impossible to recycle because it is composed of synthetic resin material and metal spring, which is the problem of conventional contents discharge pump, and recycles the discharge pump by replacing spring with elastomer without using metal spring. To make it more environmentally friendly All.

In general, one of the means for discharging and using the contents of cosmetics, shampoo, detergents, etc. contained in the container by an appropriate amount to use the discharge pump in the container.

Existing discharge pump is installed in the container as described above using a small amount of the contents discharged in various ways, but the structure of the general discharge pump is the opening and closing ball 122 and the operation piston (123) for opening and closing the contents inlet hole (125) ) Is installed to receive the elastic force of the spring 121, the pressure is applied to the contents storage chamber 126 by the operation piston 123 is made to discharge the contents in the contents storage chamber 126 through the push button 140. The cylinder 120 is installed in the pump body 110.

The operating piston 123 is further provided with a closed piston 124, the push button 140 is installed in the operating pipe 130 is fastened to the operating piston 123 of the cylinder 120.

In the conventional contents discharge pump having the above-described configuration, when the push button 140 is pressed, a gap is first generated between the sealing piston 124 and the operation piston 123, and then the sealing piston 124 and the operation piston 123 are formed. The pressure is generated in the contents storage chamber 126 while going down together, and the contents are discharged as shown in FIG. 1 through the contents transfer path 123a of the operation piston 123 by the pressure.

At this time, the opening and closing ball 122 is in close contact with the contents inflow path 125 by the spring 121 to be compressed to block the contents inflow path 125.

Pressing the push button 140 as described above to discharge the contents and then release the external force applied to the push button 140, the operation piston 123 and the sealing piston 124 by the resilient elastic force accumulated in the spring 121 ) Will rise together as in FIG.

As described above, the actuating piston 123 and the sealing piston 124 ascend the actuating piston 123 at the initial stage of the ascending to close the air gap generated between the actuating piston 123 and the hermetic piston 124 to transfer contents. The furnace 123a is blocked, and the elastic force accumulated in the spring 121 is weakened.

As the operation piston 123 and the sealed piston 124 continuously rise in the state in which the contents transfer path 123a is blocked as described above, a vacuum pressure is generated in the contents storage chamber 126 and the contents storage chamber 126. The opening / closing ball 122 is spaced apart from the contents inlet hole 125 by the vacuum pressure generated therein, and the contents in the container are introduced again into the contents storage chamber 126.
