Pumping device for liquid container with stopper {PUMPING DEVICE WITH 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 stopper for preventing the pushbutton from operating during product distribution.

In general, a liquid container, which 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 catching 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 improve the cap housing structure of the pumping device to provide a pumping device for a liquid container having a stopper that can prevent the operation of the button portion by non-artificial external force.

In addition, another object of the present invention is to provide a pumping device for a liquid container having a stopper that can be easily removed by the user to configure the stopper integrally to the cap housing.

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 side, and a stopper 50 for limiting the lowering operation of the hollow piston 45.

Cap housing 41 is made of a cylindrical shape is coupled to the inlet 31 of the liquid container 30 by a screw method, for this purpose the female screw 41a is processed inside the cap housing 41.

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 the lower end is accommodated to move up and down in the cylinder 42, the upper end thereof is fitted into the communication path (43b) of the push button 43 is coupled. 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 lowered integrally while pressing the coil spring 44, whereby the liquid in the pressure chamber 42a is pressurized, and the piston 48a is continuously elastic. As it is deformed, it is heard from the piston support member 48b. Therefore, the liquid in 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 stopper 50 is provided to surround the hollow piston 45 to prevent its up and down operation, the consumer who purchased the product can be used after removing it.

2 and 3, the stopper 50 having such a function is arranged to surround the upper end of the hollow piston 45 extending out of the cap housing 41, and the ring abuts against the lower end of the pushbutton 43. Form. That is, the ring stopper 50 is integrally formed at the center of the upper surface of the cap housing 41, so that when the pumping device 40 is assembled, the hollow piston 45 is disposed therethrough and the upper end thereof is pushed. It comes into contact with the lower end of the button 43.

3 and 4, in order to easily disassemble the stopper 50, there is a notch line 52 extending in the longitudinal direction to allow notches from side to side, and an adjacent portion of the notch line 52. Handle portion 51 provided to protrude in is made integral. In addition, the lower end of the stopper 50 is integrally configured through the cutting line 53 at the center of the upper surface of the cap housing 41.

Therefore, when the user grabs the handle 51 and pulls it out forcibly, the ring-shaped stopper 50 is separated from the left and right through the cut line 52 and the cut line 53 is cut off from the cap housing 41. Will be.

In addition, the ring-shaped stopper 50 has a folding line 54 in a direction perpendicular to the cutout line 52 so that the stopper 50 can be easily cut. This folding line 54 is for the easy disassembly of the rest of the stopper 50 in the process of disassembling the other part is folded to the opposite side.

Next will be described the operation and the effects of the stopper according to the present invention configured as described above.

First, when the cap housing 41 having the stopper 50 integrated therein is coupled to the storage container 30 in which the liquid A is stored, and the product assembly is completed, the push button 43 may be applied even when an external force is applied during product distribution. Along with the hollow piston 45, the lowering operation is not made. Accordingly, when the product is distributed, the contents contained in the storage container 30 do not leak (aka, leakage phenomenon), so that product reliability may be further improved.

Since the stopper 50 is configured integrally at the time of forming the cap housing 41, the assembling work is made easier.

In addition, after the consumer purchases the product and uses it, the stopper 50 must be disassembled. Therefore, as shown in Figure 5 and 6, when holding the handle portion 51 and pull it, the stopper 50 of the ring shape is cut to the left and right through the cut line 52 and at the same time the cut line 53 is also broken cap It is cut apart from the upper surface of the housing 41. At this time, after cutting about half of the stopper 50 and folding it to the opposite side through the folding line 54, the other half is easily cut.

On the other hand, when the push button 43 is pressed in the state in which the stopper 50 is disassembled and removed, as illustrated in FIG. 7, the coil spring 44 is compressed while the hollow piston 45 descends. At this time, the piston 48a is lowered together with the hollow piston 45 to pressurize the liquid 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. In addition, the ball valve 46 rises upward due to an air 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 passes through the hose 47. 42a).

As described in detail above, according to the pumping apparatus of the liquid container with a stopper according to the present invention; A ring-shaped stopper is provided to detach the hollow piston on the upper surface of the cap housing and prevents the operation of the hollow piston in contact with the lower end of the push button. A notch line and a handle portion provided to protrude from an adjacent portion of the notch line.

Therefore, even if an external force is applied to the push button during product distribution, the lowering operation is prevented by the push button, thereby preventing the contents from leaking. In addition, when a consumer purchases and uses a product, the stopper is easily disassembled and removed while being cut along the cut line when the handle part is pulled out.
