It includes an inner hollow tube 20, the upper end of which communicates with the inlet (11).

As shown in Figure 3 (b) and 4 (b), the above-described container 10,

When the button 19 is pressurized so that the contents from the container 10 can be sucked into the pump body 14 by the suction force through the inlet 11 which is opened when the external force pressurized the button 19 is removed. 10) includes a piston 21 moved in close contact along the inner surface.

It includes a stopper 22 formed on the inner side of the solder 17 to limit the amount of falling of the button 19 so that the discharge amount of the contents from the pump body 14 can be adjusted when the button 19 is pressed. .

The conical part 23 is formed at the lower end of the guide nozzle 16 so that the opening of the pump body 14 is opened earlier than the pumping action of the pump body 14 due to the pressurization of the button 19. Correspondingly, the inclined surface 24 is formed on the inner surface of the pump body 14.

The valve 12 seated on the pump base 13 described above and opened in one direction to open and close the inlet 11 includes a fixed plate 25 placed between the pump base 13 and the pump body 14, The check ball 26 to open and close the inlet 11, and the check ball 26 is connected to the fixed plate 25 in a single body, so as to open the inlet 11 when removing the external force pressurized button 19 And an elastic piece 27 (referring to an elastic rib formed to be soft so as to be elastically deformed and restored, for example) to return the check ball 26 spaced apart from the seating surface 30 to an initial position.

In the drawing, reference numeral 28 denotes a nozzle which is coupled to the above-described discharge port 18 and discharges the contents from the pump body 14 to the outside through the moving passage 15 in response to the pressurization of the button 19. 19 is an air hole through which the outside air flows when the contents of the container 10 are sucked into the pump body 14 by the suction force of the pump body 14 when pressurizing, and 32 is a cap coupled to the outside of the solder 17. , 40 is a packing to prevent the contents from leaking from the container 10 through the contact surface gap between the container 10 and the solder 17.

Hereinafter, a use example of a pump of a liquid storage container according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 (a, b) and 4 (a), when the user presses the button 19 to use the contents such as the cosmetic liquid contained in the container 10 described above, the button 19 is The corrugated pump body 14 is compressed by the guide nozzle 16 which descends along the inner surface of the solder 17 and connects the button 19 and the pump body 14 as a single body.

Accordingly, an annular gap 29 is generated between the conical portion 23 formed at the lower end of the guide nozzle 16 and the inclined surface 24 formed in the pump body 14 correspondingly.

For this reason, the contents, such as the cosmetic liquid stored in the pump body 14, in order to pump the action of the pump body 14, the inlet hole 16a of the guide nozzle 16 and the moving passage 15 in order. Passes through and discharges to the outside through the nozzle 28 formed in the button 19 (that is, when the button 19 is pressurized, the gap 29 is generated before the pumping action due to the compression of the pump body 14). Opening of 14 is opened).

At this time, the inlet 11 of the pump base 13 coupled to the opening of the container 10 described above maintains the initial state closed by the check ball 26 of the valve 12 seated on the pump base 13. do. As a result, the contents stored in the container 10 are not allowed to move into the pump body 14 through the inlet 11.

On the other hand, when the button 19 is lowered along the solder 17 due to the press by the user, the amount of movement of the button 19 is limited by the stopper 22 formed on the inner surface of the solder 17. That is, since the amount of movement of the button 19 is limited depending on the kind of the contents contained in the container 10 (for example, a cosmetic liquid or a detergent liquid each having a different viscosity), the amount of discharge of the contents through the nozzle 28 is limited. Is determined.

3 (a, b) and 4 (b), the contents stored in the pump body 14 are discharged through the nozzle 28 by pressing the button 19 described above, and then the button 19 is released. When the pressurized external force is removed, the button 19 is returned to the initial position along the inner surface of the solder 17. In addition, the pump body 14 is also returned to the initial position by the elastic restoring force.

At this time, before the pump body 14 is completely returned to the initial position, the conical portion 23 of the guide nozzle 16 and the inclined surface 24 of the pump body 14 corresponding thereto are in close contact, so that the pump body 14 The opening of is first sealed.

That is, after the opening of the pump body 14 is sealed, the check ball 26 of the valve 12 closing the inlet 11 due to the return of the pump body 14 opens the inlet 11. That is, the check ball 26 is spaced apart from the seating surface 30 of the pump base 13 by the restoring force of the pump body 14. At this time, the check ball 26 may be spaced apart from the seating surface 30 due to the elastic deformation of the elastic piece 27 in which the check ball 26 is connected to the fixed plate 25 seated on the pump base 13 as a single body. .

This causes the contents stored in the container 10 to be moved into the pump body 14 through the inlet 11. That is, when the button 19 is pressurized, the contents from the container 10 are introduced into the pump body 14 through the inlet 11 in an amount corresponding to the contents discharged from the pump body 14.

On the other hand, after the contents from the container 10 described above flow into the pump body 14, the check ball 26 of the valve 12 is filled with the weight of the contents filled in the pump body 14 and the elastic pieces 27. It is seated on the seating surface 30 by the restoring force. That is, since the inlet 11 is maintained in the closed state by the check ball 26, the movement of the contents from the container 10 into the pump body 14 is no longer allowed.

3 (a) and 4 (a) is a pump for a liquid storage container according to an embodiment of the present invention, a container in which a tube (so-called "deep tube") is built (for example, a shampoo container, etc.) Is a diagram showing that a pumping device is applied. That is, due to the pumping action of the pump body 14 when the button 19 is pressed, the contents in the container 10 are sucked into the pump body 14 through the tube 20 and the inlet 11.

3 (b) and 4 (b) is a pump for a liquid storage container according to an embodiment of the present invention, the pumping device in a container (in one example, refers to an airless cosmetic container) in which the piston 21 is built Is a diagram showing that is applied. That is, the contents in the container 10 are sucked into the pump body 14 through the inlet 11 due to the pumping action of the pump body 14 when the button 19 is pressed.

At this time, since the pumping force of the pump body 14 is transmitted into the container 10, the piston 21 (contents leak into the bottom surface of the container 10 or air is in close contact with the inner surface of the container 10). The airtightly coupled to the inner surface of the container 10 to prevent oxidation, contamination or alteration of the contents due to the inflow.

Therefore, the contents of the container 10 are pushed up by the rising of the piston 21, so that the contents of the container 10 are sucked into the pump body 14 through the inlet 11.

According to the pump of the liquid storage container according to an embodiment of the present invention as described above, the spring, the ball, etc. of the metal material for opening and closing the opening of the container in which the liquid contents are accommodated is unnecessary, harmless to the human body, recyclable It is environmentally friendly.

In addition, by reducing the number of parts of the pump mounted in the opening of the container to reduce the cost and manufacturing cost, and the parts of the pump are combined with each other to be easily assembled to facilitate mass production.

In addition, airtightness at the opening of the check valve and corrugated pipe opening and closing the opening of the container prevents leakage of liquids and the like, and can be applied to a container capable of refilling the contents by selectively attaching and detaching the pumping device to the container. .
