According to the present invention, when the push button is operated by pumping, the contents inflow path is selectively blocked or opened to enable the discharge of contents that have flowed into the contents storage chamber of the cylinder and the contents can be introduced again into the contents storage chamber where the contents have been discharged. The present invention relates to a discharge pump including an opening and closing ball for selectively opening or closing an inflow path, and more particularly, a opening and closing ball and a push button for selectively opening or closing a cylinder contents inflow path. The springs are placed to ensure the inflow and outflow of the contents in the cylinder, and at the same time, both the repulsive force to push up the push button and the open / close ball receive the appropriate repulsive force, like the spring used in the conventional discharge pump. No need to equip to make spring It relates to devise a relieve the sourness on the production accordingly.

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.

Existing discharge pumps equipped with a container and discharging the contents in small amounts are devised in various ways. Among them, the discharge pump in contrast to this filing case is shown in Utility Model Registration No. 382941 as follows. same.

In the pre-registration scheme, as shown in FIG. 1, the opening / closing ball 122 for opening and closing the contents inflow passage 125 is installed to receive the elastic force of the spring 121, and is installed to receive the elastic force of the spring 121. A cylinder 120 including an operation piston 123 for applying pressure in the storage chamber 126 to discharge the contents in the contents storage chamber 126 through the push button 140 is installed in the pump body 110.

The working piston 123 is further provided with a sealing piston 124.

The push button 140 is installed in the operation pipe 130 fastened to the operation 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 of the cylinder 120, and then the sealing piston 124 and As the working piston 123 goes down together, pressure is generated in the contents storage chamber 126, and the contents are discharged as shown in FIG. 2 through the contents conveying path 123a of the working piston 123 by the pressure. You lose.

At this time, the opening and closing ball 122 is in close contact with the contents inflow path 125 by the repulsive force of the spring 121 is 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.

The operating piston 123 and the sealing piston 124 rising as described above are operated between the operating piston 123 and the sealing piston 124 when the operating piston 123 is first raised to press the push button 140 at the initial stage of the rising. As the voids generated in the disappearance disappear, the contents transport path 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 and closing ball 122 is spaced apart from the contents inflow path 125 by the vacuum pressure generated in the contents to be introduced again into the contents storage chamber 126.

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

However, in the conventional contents discharge pump, as shown in FIGS. 1, 2, and 3, the opening / closing ball 122 for opening and closing the contents inflow passage 125 receives a repulsive force generated from one spring 121. Therefore, the elastic force of the spring 121 to have a resilient elastic force that can be smoothly pumping operation of the push button 140, and also to allow the contents to be smoothly introduced into the contents storage chamber 126 of the cylinder 120 Since it is necessary to have a resilient elastic force that can support the opening and closing ball 122, the precise processing of the spring is indispensable, and the manufacturing cost of the discharge pump is increased due to the difficulty in manufacturing and the increase in the production cost due to the precision processing. Becomes

In addition, when the discharge pressure is not generated in proportion to the resilience value of the spring in the contents storage chamber 126 of the cylinder 120 due to the assemblage of the exhaust pump must be assembled precisely, the opening and closing ball 122 ) Is not able to support the contents inflow path (125) to cause the failure of the discharge of the contents, as well as the discharge pump that is not used because of it can not be mass produced.

The discharge pump discarded as described above is in a situation where it is disposed of rather than separated collection because of economical efficiency due to separate collection and recycling, thereby increasing the environmental pollution caused by waste as well as waste of resources.

The present invention was devised to solve the shortcomings of the conventional contents discharge pump, and its purpose is to selectively open and close the contents inflow path of the cylinder constituting the discharge pump to enable the contents discharge in the contents storage chamber and the contents storage chamber at the same time. The resilient elastic force of the opening and closing ball to enable the inflow of the contents of the furnace is elastically supported by the first spring having a small resilience elasticity, and the push button and the discharge pipe which are installed through the push button and the discharge pipe so as to enable the pumping operation of the push button. As it is elastically supported by the second spring that occurs, the discharge pump of this case has two springs that can satisfy the resilient elastic force that can support the opening and closing ball as well as the resilient elastic force that can satisfy the pumping operation of the pushbutton on one spring. In the fabrication that had to produce a spring with resilience of the requirements The exhaust pump of the case application is that the opening and closing ball is elastically supported by a separate first spring having a weak rebound elastic force, so that suction pressure proportional to the spring resilience of the spring is generated in the contents storage chamber as in the prior art. Even if you do not do this, the opening and closing of the ball from the contents inlet flows smoothly, so it is not necessary to assemble precisely, which improves the assembly productivity and eliminates the waste pump that is disposed of due to malfunction. It is to provide a structure of the content discharge pump that can be significantly reduced.

The present invention for achieving the above object, the pumping operation of the push button to selectively block or open the content inflow path to enable the discharge of the contents that were introduced into the contents storage chamber in the cylinder and at the same time the contents storage chamber In the discharge pump including an opening and closing ball for selectively opening or blocking the contents inlet passage so that the contents can be introduced again to,

The lower end is placed on the rib ribs 23 formed in the contents inflow passage 22 and the contents storage chamber 29 adjacent to the cylinder tube 21 and connected to communicate with the discharge pipe 30 of the push button 40. The push button 40 is pumped by the repulsive elastic force of the second spring 27 supporting the lower end of the operated piston 24, and the upper end is positioned inward of the second spring 27 so that the upper end of the actuated piston 24 The opening and closing ball 26 is introduced by the resilient elastic force of the first spring 28 supporting the lower portion of the opening 24 and the lower end is elastically supporting the upper portion of the opening and closing ball 26 positioned on the contents inflow passage 22. It can be achieved by the contents discharge pump structure characterized in that the contents of the contents storage chamber 29 is discharged while being selectively supported from the furnace 22 and the contents are introduced into the contents storage chamber 29.
