Description

Content discharge pump {CONTENTS EXHAUST PUMP}

The present invention relates to a discharge pump for the contents mounted in 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. In detail, this is a domestic utility model registration filed by the applicant in advance. The structure of the pushbutton elevating member, which is a valve-elastic body, in 0427103 (contents discharge pump structure;

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 is to use the discharge pump mounted on the container.

As described above, the conventional discharge pump that is mounted to the container and discharges the contents in small amounts has been variously conceived, but the structure of the general discharge pump is open and close the contents inlet hole 125, as shown in the accompanying drawings The opening and closing ball 122 and the operating piston 123 is installed to receive the elastic force of the spring 121, the pressure is applied to the contents storage chamber 126 by the operating piston 123 to the contents in the contents storage chamber 126. The cylinder 120 is configured to be discharged through the push button 140 is installed in the pump body (110).

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

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 through the contents transport 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.

As described above, when pressing the push button 140 to discharge the contents and then release the external force applied to the push button 140, as shown in Figure 2, the resilient elastic force accumulated in the spring 121 By the operation piston 123 and the sealing piston 124 is raised together.

As described above, the actuating piston 123 and the sealed piston 124 rise as the actuating piston 123 first ascends and the air gap between the actuating piston 123 and the hermetic piston 124 is closed to close the contents transport path. 123a is blocked, and the elastic force accumulated in the spring 121 is weakened.

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

The conventional contents discharge pump is to discharge the contents while repeating the above operation continuously.

The main disadvantage of the conventional contents discharge pump is that the spring which is the repulsion means is a metal material, and the opening and closing means for enabling the discharge and use of the contents is a metal ball so that the metal spring and the metal ball are corroded by the contents to contaminate the contents. There was a problem.

The discharge pump that improves the disadvantages of the conventional discharge pump described above is the applicant's pre-registration proposal.

The pre-registration proposal was to prevent the deterioration of contents due to corrosion by replacing the springs with elastomers and using synthetic resin valves instead of using metal rebound springs and metal balls. However, the pushbutton lifting members (first body) Since the content discharge hole of the valve) is in direct contact with the contents, the elastomer hardening phenomenon occurs at the parts in contact with the contents, and it becomes impossible to quantitatively discharge the contents, thereby degrading the reliability of the product.

In addition, the conventional contents discharge pump is composed of a synthetic resin material and a metal material, when using all the products and the separate collection, the contents discharge pump has a problem that is not good for the environment because the resources can not be recycled and had to be disposed of.

It can prevent the irregular discharge of the contents, and push button lifting part made of elastomer The can contents by the contact address the problem that the contents are altered.

In addition, by not using a metal material other than the synthetic resin material in the conventional contents discharge pump, that is, by using a synthetic resin valve instead of a metal ball, and by using an elastomer instead of a metal spring, the discharge pump can be recycled after all the products are used. To provide an eco-friendly contents discharge pump.

The present invention for achieving the above object is, when the push button is pressed, the deformation of the shape by the operation of the connection pipe mounted on the pump, and when the state is released, the connection pipe and the push button to the original state by its own repulsive force It has an elastic means for recovering, The elastic means is stretched when an external force is applied, the elastic action portion to contract when the external force is released; A fixing part provided at one end of the elastic functioning part and fixed to the outside of the contents discharge path; Combined with the connection transfer pipe in the other end of the elastic action portion is provided in the same body, while receiving the external force through the connection transfer pipe at the push button side, while transmitting its own elastic force through the connection transfer pipe to the push button side Including the action transmission portion, wherein the fixing portion is provided with a release preventing member 1 for preventing the deformation due to the operating pressure of the connection transport pipe, the action transfer portion is prevented from being separated from the coupling state with the working piston rod.
