Pumping device for liquid container with moving stopper {PUMPING DEVICE WITH MOVING STOPPER FOR LIQUID VESSEL}

The present invention relates to a pumping apparatus for a liquid container, and more particularly to a pumping apparatus for a liquid container having a movable stopper for preventing the pushbutton from operating during product distribution.

In general, a liquid container that stores liquid or paste-like cosmetics or other contents is provided with a pumping device for discharging a predetermined amount by air pressure.

As shown in FIG. 1, the conventional pumping apparatus for a liquid container is coupled to an inlet (not shown) of the liquid container and has a pumping part 10 in which a pressure chamber 11a is formed so that the liquid is pumped and temporarily stored therein, and the pumping device 10. The button unit 20 is provided with a jet port 21 for applying a pressure to the pressure chamber 11a of the section 10 to eject the pumped liquid to the outside.

The pumping part 10 is provided coaxially at the inner center of the cap housing 12 mounted at the inlet of the liquid storage container, and has a cylinder 11 having a pressure chamber 11a therein, and a pressure chamber of the cylinder 11. A coil spring 13 provided at 11a, a hollow piston 14 elastically supported at an upper end of the coil spring 13, and having a through hole 14a formed at one side thereof, and the hollow piston 14 slidably penetrates. And a cylinder cap 15 for closing the upper end thereof, a connecting pipe 16 for connecting the ejection opening 21 and the hollow piston 14 of the button part 20, and a locking jaw 11b at the bottom of the cylinder 11. It is provided with a ball valve 17 of the steel sphere to be placed).

Accordingly, when the user presses the button unit 20, the hollow piston 14 descends along the inside of the cylinder cap 15 while overcoming the elastic force of the coil spring 13, whereby the pressure chamber of the cylinder 11 ( The liquid filled in 11a) is ejected to the outside through the through hole 14a → the hollow part of the hollow piston 14 → the connecting pipe 16 → the spout 21. At this time, the ball valve 17 abuts against the latching jaw 11b by the lowering pressure of the liquid inside the cylinder 11 to block communication between the pressure chamber 11a and the inside of the liquid container.

When the user releases the button unit 20, the hollow piston 14 rises along the inside of the cylinder cap 15 by the elastic support force of the coil spring 13, and the through hole 14a is closed to stop the liquid discharge. A vacuum is formed in the pressure chamber 11a of the cylinder 11. Therefore, the liquid stored in the liquid reservoir is filled in the pressure chamber 11a while raising the ball valve 17. By repeatedly pressing the button unit 20, the liquid in the liquid reservoir is constantly discharged.

However, the pumping apparatus of the conventional liquid storage container is not provided with a separate configuration for preventing the pressing operation of the button portion 20, so that the contents contained in the storage container leaks during product distribution.

That is, there is a case in which the button unit 20 of the pumping device is pressed by an external force, not artificial, during the distribution of the product. In this case, the button unit 20 operates without any resistance, and there is a problem in that leakage occurs.

The present invention is to solve this problem; An object of the present invention is to provide a pumping apparatus for a liquid container having a movable stopper that can prevent the operation of the button unit by an external force by installing a stopper in the cap housing of the pumping apparatus.

In addition, another object of the present invention is to provide a pumping apparatus for a liquid container having a movable stopper that allows the user to arbitrarily manipulate or disable the stop function.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

2, the liquid A is stored in the liquid storage container 30 to which the present invention is applied, and the liquid A stored at the inlet 31 of the liquid container 30 by a manual pressing operation of the user. ) Is equipped with a pumping device 40 for pumping and ejecting.

The pumping device 40 according to the present invention has a cap housing 41 mounted to the inlet 31 of the storage container 30, and is installed in the cap housing 41 and pressured so that the liquid A is sucked and temporarily stored. A cylinder 42 having a seal 42a, a push button 43 mounted on the upper portion of the cap housing 41 and having a blowout port 43a at one side thereof, and a vertical movement of the cylinder 42 can be performed. And a hollow piston 45 for guiding the liquid A in the pressure chamber 42a toward the pushbutton 43, and a movement stopper 50 for selectively limiting the lowering operation of the pushbutton 43. have.

The cap housing 41 has a cylindrical shape and is coupled to the inlet 31 of the liquid container 30 by a screw method. For this purpose, a female screw 41a is processed inside the cap housing 41. At the center of the upper surface of 41), a cylindrical guide 41b for guiding the upper end of the hollow piston 45 to be relaxed is provided integrally. The movement stopper 50 is attached to this guide 41b so that a movement to the left-right horizontal direction is possible.

And the cylinder 42 is configured in a cylindrical shape with the upper and lower portions open, the upper end is firmly mounted to the inner center of the cap housing 41. Accordingly, the cylinder 42 is installed coaxially in the cap housing 41, and a pressure chamber 42a in which the liquid A is sucked and temporarily stored and the coil spring 44 is disposed is formed therein. . In addition, a valve seat 42c (valve seat) is formed at the lower end of the cylinder 42 so that the ball valve 46 is seated, and a hose extending to the bottom of the storage container 30 at the bottom of the cylinder 42. (47) is fitted. Therefore, the liquid A in the storage container 30 is sucked into the pressure chamber 42a of the cylinder 42 through the hose 47. Reference numeral "42b" is a negative pressure hole formed in the wall of the cylinder 42 so that the outside air enters the storage container 30 when the liquid A is sucked into the pressure chamber 42a.

Push button 43 is mounted to the upper and lower movements in the upper portion of the cap housing 41, the communication path 43b associated with the spout 43a is formed in the longitudinal direction therein. The pushbutton 43 is always elastically supported upward through the coil spring 44. That is, the coil spring 44 is installed inside the pressure chamber 42a of the cylinder 42 to support the push button 43 upward through the hollow piston 45.

And the hollow piston 45 is accommodated in the lower end is to be moved up and down in the cylinder 42, the upper end of the inside of the communication path 43b of the push button 43 while passing through the guide 41b of the cap housing 41 Fitted in and combined. In addition, the lower end of the hollow piston 45 is integrally raised and lowered by a piston assembly 48 for guiding the liquid A in the pressure chamber 42a into the hollow piston 45.

The piston assembly 48 is fitted to the outer wall of the lower end of the hollow piston 45 and coupled to the inner wall of the cylinder 42, and is coupled to the lower end of the hollow piston 45 to support the piston 48a. The piston support member 48b is provided. In addition, a communication hole 48c communicating with the hollow piston 45 is drilled in the piston support member 48b, which is opened and closed through the piston 48a. That is, when the hollow piston 45 is lowered, the piston 48a is also integrally lowered while pressing the coil spring 44. As a result, the liquid in the pressure chamber 42a is pressurized and the piston 48a is elastically deformed. While being heard from the piston support member 48b. Therefore, the liquid A of the pressure chamber 42a is discharged to the outside through the communication hole 48c, the hollow piston 45, and the push button 43.

On the other hand, the movement stopper 50 is disposed on the upper portion of the cap housing 41 so as to be movable in a left and right direction to selectively limit the downward movement of the push button 43. To this end, the movement stopper 50 is injection molded through a synthetic resin (plastic), and the bottom surface 51 and the top of which are coupled to the guide 41b of the cap housing 41 so as to be movable in the horizontal direction are opened. It consists of a side surface 53.

3 and 4, the bottom surface 51 of the movement stopper 50 is formed to be perforated to be coupled to the guide 41b of the cap housing 41 while the movement stopper 50 is elastically deformed to either side. The coupling mechanism 52 in the form of a janggu is perforated to move and maintain a moving state. As a result, the moving stopper 50 is eccentrically disposed on the upper side of the cap housing 41 by the coupling tool 52 in the form of a gear.

And the side 53 of the movement stopper 50 is made of a large curvature compared to the curvature of the pushbutton 43, semi-circular lowering allowance 53a for allowing the pushbutton 43 to descend, and the lowering allowance 53a. It is defined as a semi-circular lowering prevention portion (53b) is made in the same manner as the curvature of the push button (43) to prevent falling of the push button (43).

That is, the semi-circular descending allowance 53a is configured to accommodate the lower end of the pushbutton 43 with room. Therefore, as shown in FIG. 5, when the movement stopper 50 is moved to the right (arrow A direction), the semi-circular lowering allowance 53a is positioned directly under the pushbutton 43, and thus the pushbutton The lowering operation of 43 is allowed.

On the other hand, the semi-circular falling prevention portion 53b is composed of the same curvature as the push button 43. Therefore, as illustrated in FIG. 6, when the movement stopper 50 is moved to the left side (see arrow B direction), the semi-circular anti-dropping portion 53b is positioned directly under the pushbutton 43, thereby pushing. The lowering operation of the button 43 is not made.

Next, the operation of the pumping device 40 equipped with the movement stopper 50 according to the present invention configured as described above and the effects thereof will be described.

First, as shown in FIG. 5 and FIG. 7, when the movement stopper 50 is pushed to the right (arrow A direction), the bottom surface 51 of the movement stopper 50 is moved while being elastically deformed, When the guide 41b is completely engaged, the moving state is maintained as it is. At this time, the semi-circular lowering allowable portion 53a of the movement stopper 50 is located directly below the push button 43.

When the user presses the push button 43 in this state, the lower end thereof is lowered together with the hollow piston 45 while being accommodated in the semi-circular lowering allowance 53a of the movement stopper 50, and the coil spring 44 is compressed. . At this time, the hollow piston 45 and the piston 48a are lowered together to pressurize the liquid A in the pressure chamber 42a. Accordingly, the liquid A filled in the pressure chamber 42a of the cylinder 42 is discharged to the outside through the hollow piston 45 → the communication path 43b → the jet port 43a.

When the push button 43 is released, the push button 43 and the hollow piston 45 are gradually raised by the restoring force of the coil spring 44, and a vacuum pressure is applied to the pressure chamber 42a. Accordingly, the ball valve 46 rises upward due to the pressure difference between the pressure chamber 42a and the inside of the storage container 30, and a part of the liquid A in the storage container 30 is transferred through the hose 47. Inhaled at 42a.

Meanwhile, as shown in FIGS. 6 and 8, when the position of the movement stopper 50 is pushed to the left (arrow B direction), the bottom surface 51 of the movement stopper 50 is moved while being elastically deformed, and the coupling sphere 52 ) And the guide 41b are completely engaged, the moving state is maintained. At this time, the semi-circular lowering prevention part 53b of the movement stopper 50 is located directly under the pushbutton 43.

In this state, even if the user presses the push button 43, the lower end of the push button 43 does not come into contact with the semi-circular anti-drop protection portion 53b of the movement stopper 50 (see FIG. 8). As a result, the lowering operation of the push button 43 is not performed by the movement stopper 50, so that the liquid A is not discharged.

As a result, the lowering operation of the push button 43 can be selectively prevented through the movement stopper 50, so that the contents contained in the storage container 30 can leak (e.g., leakage) during product distribution or carrying. Product reliability can be improved.

In addition, since the movement stopper 50 is disposed to be movable from side to side at the top of the cap housing 41, there is an advantage that it can be used semi-permanently as well as its operation is easy.

As described in detail above, according to the pumping apparatus of the liquid container with a moving stopper according to the present invention; A cylindrical guide is provided at the center of the upper surface of the cap housing to surround the upper end of the hollow piston. The upper portion of the cap housing includes a bottom surface coupled to the guide so as to be movable in the horizontal direction and an upper side of the tubular shape of which the upper part is opened. A moving stopper is disposed to selectively prevent the lowering operation.

Therefore, the downward movement of the pushbutton is allowed or restricted by moving the movement stopper left and right in the guide. As a result, if the pushdown movement of the pushbutton is restricted through the movement stopper, even if an external force is applied to the pushbutton during product distribution or carrying, there is an effect of preventing the contents from leaking. In addition, since the movable stopper operates in an assembled state on the upper part of the cap housing, there is an advantage that it can be used semi-permanently as well as no loss.
