Description

Liquid container having pumping device with simple structure

The present invention relates to a fluid container, and more particularly, to a fluid container having a pumping device for allowing a user to discharge a certain amount of fluid contained in the container such as cosmetics by pressing a button.

Containers for receiving fluids, such as cosmetics, etc. are largely classified into a general form having a structure for receiving fluids and a pumping form in which a certain amount of cosmetics is discharged through a nozzle by pressing a button provided in the container. 1 is a view showing a cosmetic container as an example of a fluid container having a pumping device of such a fluid container.

As shown in FIG. 1, the fluid container includes a container part 110 for accommodating fluid, and a pumping device 200 for discharging cosmetics contained in the container part 110 to the outside.

The container portion 110 is typically formed in a cylindrical shape. The container unit 110 forms an accommodation space 111 for accommodating cosmetics therein, and a vent hole 115 is formed on a lower surface of the container unit 110.

The container piston 113 is provided in the container unit 110. As the cosmetics contained in the accommodation space 111 is leaked to the outside by the pumping device 200 and the amount thereof is reduced, the container piston 113 gradually increases by the negative pressure in the accommodation space 111. To rise. At this time, since the outside air may be introduced into the container unit 110 through the vent hole 115, the lifting of the container piston 113 is not disturbed.

The pumping apparatus 200 may include a nozzle cap 220 installed at an upper portion of the container 110, a nozzle button 210 installed at an upper portion of the nozzle cap 220, and a cylinder 230 installed at a lower portion of the nozzle cap 220. The upper plunger 260 and the lower plunger 270 installed to penetrate the nozzle cap 220 and the spring 240 and the ball 250 installed in the cylinder 230 are included.

The nozzle cap 220 is fixed to the upper portion of the container portion 110 to provide a frame for installing the entire pumping device 200 on the container portion 110. A gasket 223 is installed between the nozzle cap 220 and the upper end of the container 110 to maintain an airtight state between the container 110 and the nozzle cap 220.

The nozzle button 210 is coupled to the upper plunger 260 at the top of the nozzle cap 220, the nozzle 213 is provided on the side of the nozzle button 210. The nozzle 213 provides an outlet through which the cosmetic finally flows out when the user presses the nozzle button 210.

The upper portion of the upper plunger 260 is coupled to the nozzle button 210 and the lower portion of the upper plunger 260 is coupled to the upper portion of the lower plunger 270. Therefore, as the user presses the nozzle button 210, the upper plunger 260 and the lower plunger 270 together with the nozzle button 210 are lowered together.

The cylinder 230 is disposed in the container 110, and the inlet 233 is formed at the lower end thereof to allow the cosmetics in the accommodation space 111 to flow into the cylinder 230. The ball 250 is provided near the inlet 233 in the cylinder 230.

The lower portion of the lower plunger 270 is accommodated in the cylinder 230, and the spring 240 is disposed between the lower end of the lower plunger 270 and the ball 250. Therefore, the lower plunger 270 is pressed upward by the elastic force of the spring 240, and the ball 250 is maintained in a state in which the inlet 233 of the cylinder 230 is closed.

On the other hand, the nozzle button 210, the upper plunger 260 and the lower plunger 270 is formed with flow paths 217, 267, 277 are formed to communicate with each other. The flow path 217 of the nozzle button 210 is connected to the nozzle 213, and an end of the flow path 217 of the lower plunger 270 is located in the cylinder 230. At this time, in a state where the lower plunger 270 is pressed upward by the elastic force of the spring 240 as shown in FIG. 6, the end opening of the flow path 277 of the lower plunger 270 is closed by the inner wall of the cylinder 230. In the state where the lower plunger 270 is moved downward, the distal opening of the flow path 277 of the lower plunger 270 is moved into the cylinder 230 to be opened in the inner space of the cylinder 230.

The pumping operation of the conventional fluid container having such a structure is performed as follows.

When the user presses the nozzle button 210 downward using a finger, the upper plunger 260 and the lower plunger 270 move downward together with resistance to the elastic force of the spring 240. In this case, the ball 250 strongly closes the inlet 233 of the cylinder 230 by the downward elastic force of the spring 240, and the flow path 277 of the lower plunger 270 is opened in the cylinder 230. Accordingly, the cosmetics previously filled in the cylinder 230 are flow paths 277 of the lower plunger 270, flow paths 260 of the upper plunger 260, and flow paths 217 of the nozzle button 210. It is discharged to the outside through the nozzle 213 through.

When the user releases the pressurized state of the nozzle button 210, the lower plunger 270, the upper plunger 260, and the nozzle button 210 are moved upward by the elastic force of the spring 240. At this time, since the flow path 277 of the lower plunger 270 moves upward in a closed state by the inner wall of the cylinder 230, the interior of the cylinder 230 is in a negative pressure state, and the pressure inside the cylinder 230 decreases. The ball 250 resists the elastic force of the spring 240 and moves upward. Therefore, the inlet 233 of the cylinder 240 is opened, and thus the cosmetics filled in the receiving space 111 are introduced into the cylinder 240 through the inlet 233.

That is, when the user presses the nozzle button 210, the ball 240 closes the inlet 233 and the cosmetics filled in the cylinder 240 are discharged to the outside through the nozzle 213, and the user presses the nozzle button. When the pressure 210 is released, the ball 240 opens the inlet 233 so that the cosmetics in the container 110 flow into the cylinder 230.

By repeating such a process, the user can spill out a certain amount of cosmetics every time the nozzle button 210 is pressed. At this time, if the amount of cosmetics in the container 110 is reduced by the outflow of cosmetics, the container piston 113 is raised by the pressure drop in the accommodation space 111, and thus the inlet 233 of the cylinder 230 is You will always be in contact with your cosmetics.

By the way, the conventional fluid receiving container as described above has the following problems.

That is, the conventional fluid receiving container as described above is composed of a large number of small parts, as shown in Figure 1 is complicated in structure and not easy to manufacture, there is a problem that the productivity is lowered and the production cost is increased .

In addition, since the cosmetics in the container 110 flows into the cylinder 230 in order to flow out, the metal spring 240 in the cylinder 230 while the cosmetics are filled in the cylinder 230. ) Is in contact with the When a large amount of time elapses in a state where the cosmetics are in contact with the metal spring 240, the cosmetic may be deteriorated, or when the metal spring 240 is rusted, rust may be included in the cosmetics that are spilled.

The incision line 515 is formed in a cross shape. At this time, at least the protrusion 513 of the entire portion of the first valve 510 or the first valve 510 is made of a soft material. Accordingly, the incision line 515 is in a state capable of elastically opening and closing.

At this time, since the cut line 515 is formed on the protruding portion 513, the first valve 510 may allow the withdrawal of the fluid in the container portion 610 and the inflow of the fluid into the container portion 610 is blocked. Done. That is, referring to FIGS. 3 and 4, when the pressure outside the container portion 610 is less than the pressure inside the container portion 610, the incision line 515 is opened as shown in FIG. 5 to open the inside of the container portion 610. When the fluid is sucked out of the first valve 510 and discharged, and the pressure outside the container 610 is greater than or equal to the pressure inside the container 610, the cut line 515 is closed as shown in FIG. 4. Backflow of fluid into the container portion 610 is prevented.
