Abstract

The present invention is a device for discharging the contents of an airless pump type cosmetic container containing a high-performance cosmetic mainly made of extracts of natural raw materials.

The contents discharging structure of the cosmetic container of the present invention is that the contents are discharged by the pressure of the compression piston, and the piston lowered by the compression force of the nozzle button has the teeth of the support body in which the guide wheels formed on the piston support member are integrally formed with the container body. The guide protrusion of the piston support member lowered together with the piston in the engaged state passes through the protruding surface of the tooth and rests on the indentation surface between the teeth, and it stops as it is without further force, so that the contents as much as the pitch distance of the tooth It is discharged through the discharge port of this nozzle.

Once the piston is lowered, it stops in its original state, and discharges only the required amount of contents. Therefore, it is possible to prevent the loss caused by discharging more contents than necessary, and the inflow of external air or inflow of foreign substances by the pumping action. This fundamentally blocked will prevent the deterioration of the contents.

Description

Contents Discharge Structure of Airless Pump Type Cosmetics Case

The present invention mainly relates to a content discharge structure of an airless pump type cosmetic container that can be used for program cosmetics or cosmetic samples.

Recent cosmetic trends are the extraction of functional raw materials and natural raw materials for the purpose of preventing skin aging and fine wrinkles by giving skin elasticity, flexibility and moisturization by promoting metabolism due to direct nutrition or cell activation. As the availability of cosmetics containing the main ingredient is increasing, high-performance cosmetics are being developed one after another.

Such high functional cosmetics have a very high risk of deterioration compared to cosmetics composed of other chemical raw materials by refraining from adding substances such as preservatives in order to maintain the properties of natural raw material extract and minimize irritation to the skin.

The cause of such deterioration of high-performance cosmetics is the inflow of bacteria or oxygen due to contact with external air because the inflow of external air cannot be avoided even when it is built in a container. Therefore, in recent years, the application of the airless pump type container that can overcome this problem is very active.

In general, the airless pump container of a general type is equipped with a piston inside a circular or elliptical container in order to solve the problem of inflow of external air as much as the content of the airless pump container, which is a disadvantage of the general pump. By eliminating the negative pressure port, the piston rises by the discharge amount of the contents to prevent the inflow of external air. However, such an airless container requires more parts than a general pump dispenser, which is expensive, and the use of the piston is polyolefin-based, and the use of the oil- or powder-rich contents or high viscosity contents is limited.

The present invention is to improve the problems of the conventional cosmetic airless pump container as described above, as the conventional airless pump container, while fundamentally blocking the inflow of external air, there is no restriction in use due to the piston operation failure according to the type of contents. It is a technical problem of the present invention to provide a container having a simple structure and a relatively inexpensive container.

In order to solve the above technical problem, the present invention constitutes a piston having only a compression function for discharging the contents and reinforces the sealing function of the valve from which the contents are discharged. It is provided.

The container housing (1) and the container body (2) are assembled, and the aluminum decoration (3) to be covered on the container housing (1) and the overcap (4) to be covered on the container housing (1), and the container body The nozzle button locking jaw 12 is formed around the bottom of the container housing upper jaw 11 so as not to be detached and the nozzle button 10 having the contents discharge port 13 and the piston shaft assembly 14. It is assembled with the container body 2, the piston 20 having a valve opening and closing rib 21 at the center and penetrates upward from the bottom of the valve opening and closing rib 21, the upper end is the piston shaft assembly 14 The valve stopper 32 has a piston shaft 30, the piston 20, and a nozzle button 10 so that the valve stop 31 is drilled in the lower circumferential wall and is supported by the lower end of the valve opening and closing rib 21. To a known airless pump type cosmetic container with a spring 40 mounted between In

The support 100 is formed integrally with the container body 2, is placed on both sides in a vertical state from the bottom surface of the container body 2, the spacing portion 101 is formed and a plurality of teeth 102 on the main wall And a guide protrusion wheel fitted into the piston 20 and engaged with the teeth 102 of the support 100 at a lower portion of the inner wall surface 201 ′, and having an entrance space 201 of the support 100 formed therein. It consists of a piston support member 200 having a 202.

It demonstrates the effect of the present invention having the above configuration.

Figure 2 is a cross-sectional view of the present invention assembled state, Figure 3 is a cross-sectional view showing an operating state of the present invention,

In the state of FIG. 2, the overcap 4 written on the inner housing 2 is detached from the container body 2, and then the nozzle button 10 is pushed with a finger to be held between the nozzle button 10 and the piston 20. As the spring 40 is contracted, the nozzle button 10 and the piston shaft 30 are lowered, and the piston shaft 30 is lowered, and the piston is pressed. When the pressure is greater than the spring force of the spring, the piston 20 can no longer be lowered, and if the pressure is continuously applied to the nozzle button 10 by hand, the piston shaft 30 is continuously lowered and drilled into the lower circumferential wall. The valve port 31 is exposed outside the lower end of the valve opening rib by leaving the valve opening and closing rib 21 of the piston 20 (see FIG. 3).

At this time, the contents to which pressure is applied flows into the piston shaft 30 through the valve port and passes through the internal movement path of the nozzle button 10 to start being discharged to the content discharge port 13.

At the same time, the inner guide protrusion 202 of the piston support member 200 is lowered along the teeth 102 of the container body 2 and the nozzle button 10 continues to press the nozzle button 10 in this state. Pressure is applied to the piston shaft 30 and continues to descend, and a pitch of the teeth 102 formed on the support 100 is guide wheels 202 formed below the inner wall surface 201 'of the piston support member 200. Move to settle in the recess between the teeth. Even after it is seated, the contents of the interior (liquid stuffing) continue to be discharged to the contents discharge port 13, and when the contents pressure becomes lower than the pressing force of the spring 40, the piston 20 is lowered by the force of the spring 40. As the valve opening and closing ribs close the valve port 31, only the contents of the teeth as much as the stroke stroke are discharged to the outside.

Unlike the conventional pump, the present invention having the above-described configuration and operation effect prevents the inflow of external air by the pumping action, prevents the deterioration of the contents and simplifies the structure of the container, thereby reducing the production cost of the container and at the same time There is no restriction on the use according to the type of, it is possible to apply to high-functional program cosmetics and sample cosmetic containers by enabling the quantitative discharge.
