The present invention relates to a discharge pump unit of a cosmetic container that can be arbitrarily variably adjusted the discharge amount of the discharge pump to be used in combination with the cosmetic container, and more specifically, to form a protrusion having a male screw portion at the tip of the valve body, the protrusion Screw the holder having a female thread portion, the holder is moved up and down along the projection from the settle groove formed in the upper portion of the valve body, by varying the stroke of the push button through the holder, according to the stroke adjustment of the push button The discharge amount of the pump can be controlled to adjust the discharge amount according to the characteristics or usage of the product, and the discharge amount according to the purchaser's own usage can be conveniently controlled, thus enabling the common use of the discharge pump and preventing waste of contents due to excessive discharge. Discharge by stroke adjustable lifting holder This will control the emission of the pump unit.

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 installed in the container and discharging the contents in small amounts have been devised in various ways. Among them, the discharge pump in contrast to the filing case is shown in Utility Model Registration No. 382941 as an example. .

The pre-registration design is provided with an opening and closing ball 122 for opening and closing the contents inflow path 125, as shown in Figure 1 to receive the elastic force of the spring 121, is installed to receive the elastic force of the spring 121 The cylinder body 120 including the operation piston 123 for applying pressure in the contents 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 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 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 transfer 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 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. 3.

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 / closing ball 122 is spaced apart from the contents inflow passage 125 by the vacuum pressure generated therein so that the contents in the container are introduced again into the contents storage chamber 126. The conventional contents discharge pump performs the above operation. The contents are discharged continuously and repeatedly.

When applied to a cosmetic container, most cosmetic products, except for cream products, which generally use the contents of a finger or spatula, are combined with a discharge pump at the tip of the container for the convenience of use. The pressing operation alone allows the contents of the container to be discharged.

The container of the cosmetic having the discharge pump is such that the internal contents are discharged to the outside by a fixed amount by the pressure pump by the discharge pump, while preventing unnecessary waste of cosmetics, the internal contents and the user's hand is not in direct contact. It prolongs the service life of the product by preventing internal contents from being contaminated from the user's hands.

However, the discharge pump as described above has a disadvantage that only a certain amount of contents are discharged each time because a limited amount of contents stored in the contents storage chamber is discharged when the push button is pressed.

In terms of manufacturing cosmetics, this means that in the case of a large product that requires a large amount of discharge of the contents, the above-mentioned contents storage chamber should be made relatively large and the stroke of the push button should be made long, In this case, since the contents storage chamber is made relatively small and the stroke of the push button should be formed shortly, all the discharge pumps having different discharge amounts should be manufactured separately according to the characteristics or the usage of the product.

Since the discharge pump is composed of a very small combination of parts, a considerable amount of effort and attention should be paid in terms of the huge mold cost, as well as the management and supply of parts of different sizes.

In addition, even from the perspective of the consumer using the actual product, the amount of the contents discharged through the above discharge pump may be unsatisfactory according to the user's own preference in the same product, and the user using a relatively large amount of the contents. The use of the contents through the two or three pumping, there is an inconvenience caused by repeated pumping, the user who uses a very small amount is a problem that causes unnecessary waste because the excessive amount is discharged even with a single pumping.

The present invention is devised to improve the problems as described above, and forms a protrusion having a screw thread on the upper portion of the valve body, and forms a settling groove on the outside of the protrusion, and the settling groove is screwed with the protrusion By inserting the holder of the configuration, the holder is configured to rotate up and down from the projection,

The lifting stroke of the pushbutton is variable by raising and lowering the holder located on the lower side of the pushbutton, so it is possible to control the amount of discharged contents and to adjust the amount of cosmetics. It is possible to use the discharge pump in common by conveniently adjusting the optimum discharge amount according to the use.In addition, it is possible to reduce the enormous mold cost required for the manufacture of the discharge pump according to the common use, as well as to use various discharge amounts on the same product It is an object of the present invention to provide a discharge pump unit capable of adjusting the discharge amount by the lifting and lowering holder for adjusting the stroke having a feature that can improve the purchase satisfaction.

Hereinafter, preferred embodiments of the present invention will be described.

4 is a cross-sectional view of the discharge pump according to the present invention, Figure 5 is an enlarged perspective view of the top of the discharge pump according to the present invention.

In the construction of the present invention, when the push button is pumped, the contents inflow path is selectively blocked or opened to enable the discharge of contents that have flowed into the contents storage chamber in the cylinder and at the same time, the contents flow into the contents storage chamber where the contents have been discharged again. So that the contents inflow path

In the discharge pump comprising an opening and closing ball to selectively open or shut off,

The upper part of the valve body 10 is formed with a protrusion 12 in which the discharge pipe 11 is embedded, the outer surface of the protrusion 12 forms a male screw portion 13,

The protrusion 12 is screwed to the holder 20 having a female screw portion 21 formed therein, the holder 20 is elevated by rotation from the protrusion 12, the coupling with the discharge pipe 11 It is configured to interfere with each other by the falling of the push button 30.

Referring to the operation of the discharge pump unit capable of adjusting the discharge amount by the present invention stroke adjustment lifting holder by the configuration as described above in more detail by the accompanying drawings as follows.

The general discharge pump is fastened to the tip opening of the container in which the contents are stored, and is classified into an airless pump in which the contents are introduced into or discharged from the barrel in the pump or the contents in the container are discharged through a separate lifting piston.

Such a discharge pump is normally pushed down the push button 30 exposed to the tip when the lifting piston 40 in conjunction with the push button 30 is lowered, when the lifting piston 40 is lowered Since a void is generated between the piston 40 and the sealing piston 41, and the contents in the cylinder tube 42 flow into the discharge pipe 11, the end of the push button 30 connected to the front end of the discharge pipe 11 eventually. It is discharged to the outside through the discharge port.

At this time, the opening and closing ball 43 for opening or closing the contents inlet hole according to the pressure change in the cylinder tube 42 due to the lifting and lowering of the push button 30 is a spring 44 at the inner lower end of the cylinder tube 42. It is snowed by.

Such a discharge pump is to discharge only the contents filled in a predetermined volume in the cylinder tube 42, the conventional discharge pump was unable to control the discharge amount.

Accordingly, the present invention discharge pump unit is coupled to the upper surface of the valve body 10, the holder 20, which can limit the lifting width of the push button 30, that is, the stroke, the holder 20 Since the falling width of the push button 30 is limited according to the height of the), the amount of discharge of the contents discharged through this is easily adjusted as the falling width of the push button 30 is variably limited.

That is, the upper surface of the valve body 10 is formed to project upwardly the protrusion 12 having the discharge pipe 11 accommodated therein, and the male screw portion 13 is formed on the outer circumferential surface of the protrusion 12 to form a ring holder. (20) is to be screwed.

In particular, the male screw portion 13 and the corresponding female screw portion 21 are formed in the holder 20, so that the holder 20 from the discharge pipe 11 is rotated through the rotation of the holder 20. It has a structure that can be lifted freely, and has a structure that can be inserted into the lower end of the holder 20 on the upper surface of the valve body 10 in which the lower portion of the holder 20 is located.

Accordingly, the user or the manufacturer can finely adjust the discharge amount of the contents by elevating the holder 20 according to the characteristics of the product or the inherent usage amount. The holder 20 is lifted and rotated as shown in FIG. In this case, since the falling width of the push button 30 coupled with the discharge pipe 11 is limited, the contents are discharged only within the stroke of the push button 30, so that a relatively small amount of contents are discharged.

In the case of discharging the contents at an appropriate amount, that is, a standard amount of use, when the holder 20 is rotated as shown in FIG. It is discharged.

In particular, when using a large amount due to the characteristics of the product or using a relatively large amount of content according to the user's preference, as shown in Figure 8 by rotating down to the bottom of the holder 20, the push button (30) By maximizing the stroke, the contents stored in the cylinder tube 42 inside the valve body 10 are discharged in the maximum amount. In addition, if numbers or symbols are displayed at equal intervals along the circumference of the holder 20, the discharge of the discharge pump may be measured according to the rotation of the holder 20.

Therefore, the cosmetics manufacturer can adjust the amount of the contents discharged by adjusting the position of the holder 20 in consideration of the characteristics of the product in the production stage, so it can be used in common for various products using a single discharge pump. In the case of a user, even in the case of a single product, it is possible to conveniently adjust the discharge of the contents according to the characteristics of the user, thereby reducing the waste caused by excessive discharge and improving the inconvenience of having to use the pump several times.

The discharge pump unit which can control the discharge amount by the above-described stroke adjustment lifting holder according to the present invention raises and lowers the holder located below the pushbutton, and the lifting stroke of the pushbutton is changed by the interference, thereby discharging the contents.
