The present invention relates to a pump assembly for a liquid container, and more particularly to a pump assembly for a liquid container having a locking means for preventing the operation of the push button during product distribution.

Generally, a pump assembly is installed in a liquid container that stores liquid or paste cosmetics or other contents so as to be discharged by a predetermined amount by air pressure.

As shown in FIG. 1, the conventional pump assembly of the 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, and the pumping part. The button part 20 provided with the jet port 21 for applying the pressure to the pressure chamber 11a of 10, and spraying the pumped liquid to the outside is provided.

The pumping part 10 is provided coaxially at the 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 ( The coil spring 13 installed at 11a, the hollow piston 14 elastically supported at the upper end of the coil spring 13 and having a through hole 14a formed at one side thereof, and the hollow piston 14 slidably penetrate the upper end thereof. A cylinder cap 15 for closing the opening, a connecting pipe 16 for connecting the ejection opening 21 of the button part 20 and the hollow piston 14, and a locking jaw 11b at the lower end of the cylinder 11; It is provided with a ball valve 17 (steel ball).

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, in the conventional pump assembly of the liquid container, since there is no separate configuration for preventing the pressing operation of the button unit 20, the contents contained in the liquid container leak out during product distribution.

That is, the inner cap 111 is a female screw is processed on the inner circumference to be mounted to the neck 31 of the liquid container 30 by a screw coupling method, the cylindrical guide 113 is integrally provided to protrude from the center of the upper surface. In addition, a plurality of inner-ratchet protrusions 112 are formed to protrude at regular intervals on the upper edge of the inner cap 111, and the locking bead portion 114 protrudes outward to a lower edge of the inner cap 111. It is prepared in the form. In addition, the outer cap 115 is coupled to cover the inner cap 111 with a margin, and the through hole 116 is perforated so that the cylindrical guide 113 penetrates and is exposed upward. In addition, a plurality of outer-ratchet protrusions 117 are formed at regular intervals on the inner edge of the upper surface of the outer cap 115 so as to be engaged with the inner-ratchet protrusions 112, and the lower inner wall of the outer cap 115 is caught. The bead portion 114 is accommodated in a relaxed manner and the receiving groove 118 for limiting the axial movement height of the outer cap 115 is formed in a band shape having a predetermined height h (see FIG. 4).

The inner-ratchet protrusion 112 and the outer-ratchet protrusion 117 are easily caught and engaged when the cap unit 110 is closed, while the outer-ratchet protrusion 117 is opened when the cap unit 110 is opened. The inner-ratchet protrusion 112 is configured to easily ride over. Accordingly, the cap unit 110 may be opened or closed by pressing the outer cap 115 downward so that the inner-ratchet protrusion 112 and the outer-ratchet protrusion 117 engage with each other. The pump 111 is swung to idle (refer to FIG. 5).

And the cylinder 120 is configured in a cylindrical shape with the upper and lower portions open, the top is securely mounted to the inner center of the cap unit 110. Therefore, the cylinder 120 is installed coaxially inside the cap unit 110, and the pressure chamber 121 in which the contents A are sucked and temporarily stored and the coil spring 170 is disposed is formed therein. . In addition, a valve seat 123 is formed in the lower opening of the cylinder 120 so that the ball valve 160 is seated. At the lowermost end of the cylinder 120, the suction extends to the bottom of the liquid container 30. Hose 150 is fitted. Therefore, the contents A in the liquid container 30 are sucked into the pressure chamber 121 of the cylinder 120 through the suction hose 150. Reference numeral 122 denotes a negative pressure hole drilled in the wall of the cylinder 120 such that the external air enters the liquid container 30 when the contents A are sucked into the pressure chamber 121.

The push button 130 is formed in a tubular shape formed so that the jet port 131 is protruded, it is mounted to enable the vertical movement in the upper portion of the cap unit (110). The communication path 132 associated with the ejection opening 131 is formed in the vertical direction of the push button 130. The pushbutton 130 is always elastically supported upward through the coil spring 170. That is, the coil spring 170 is installed in the pressure chamber 121 of the cylinder 120 to support the push button 130 upward through the hollow piston 140.

And the hollow piston 140 is the lower end is to be allowed to move up and down in the cylinder 120, the upper end of the communication path 132 of the push button 130 while passing through the cylindrical guide 113 of the cap unit 110 ) Fits inside and is combined. In addition, the lower end of the hollow piston 140 is integrally raised and lowered to operate the piston assembly 180 for guiding the contents (A) in the pressure chamber 121 into the hollow piston 140.

The piston assembly 180 is coupled to the lower outer wall of the hollow piston 140 and coupled to the inner wall of the cylinder 120, and is coupled to the lower end of the hollow piston 140 to support the piston 181. The piston support member 182 is provided. In addition, the piston support member 182 is perforated with a communication hole 183 in communication with the hollow piston 140, which is to be opened and closed through the piston 181. That is, when the hollow piston 140 descends, the piston 181 is also lowered integrally while pressing the coil spring 170, whereby the contents A of the pressure chamber 121 are pressurized and the piston 181 continues. Is elastically deformed and heard from the piston support member 182. Therefore, the contents A of the pressure chamber 121 are discharged to the outside through the communication hole 183, the hollow piston 140 and the push button 130.

On the other hand, the locking means 190 is for the user to arbitrarily limit the lowering operation of the push button 130, the inner-locking jaw 191 and the cylindrical guide 113 provided to protrude to the inner wall of the push button 130, The locking unit 192 is disposed between the cap unit 110 and the pushbutton 130 while surrounding the wall, and the inserting groove 193 is formed in the longitudinal direction so that the inner-locking jaw 191 can be inserted into the wall. have.

Inner-locking jaw 191 is provided to protrude to the inner wall of the push button 130, in the embodiment of the present invention is shown to extend from the top to the lower end. However, the inner-locking jaw 191 can of course achieve the desired purpose of the present invention even if configured in the lower portion of the inner wall of the push button 130.

In addition, the locking member 192 has a cylindrical shape having an upper and lower portions open to be disposed between the cap unit 110 and the push button 130, so that the locking member 192 is accommodated in the push button 130 when the push button 130 descends. That is, when the locking member 192 is turned to match the inner-locking jaw 191 and the insertion groove 193, the lowering operation of the push button 130 is allowed, and the inner-locking jaw 191 and the insertion groove 193 are provided. If the mismatch between the inner-locking jaw 191 is caught on the upper surface of the locking member 192, the lowering operation of the push button 130 is limited. In addition, a plurality of locking projections 194 are formed at regular intervals on the outer wall of the lower end of the locking member 192 so as to be forcibly fitted to the lower end of the push button 130 when the push button 130 descends to the maximum. Therefore, when the push button 130 is pressed as much as possible while the inner-locking jaw 191 and the insertion groove 193 are aligned, the locking member 192 is forcibly held in the push button 130 by the plurality of locking protrusions 194. It is coupled (see Fig. 5), thereby causing the locking member 192 to move integrally with the pushbutton 130 unless it is artificially pulled out.

In addition, the upper end of the locking member 192 is provided with a stopper part 195 protruding in a stepped form that allows the user to turn the locking member 192 to some extent to abut on the side of the inner-locking jaw 191. The stopper portion 195 is for easily setting whether the inner catching jaw 191 and the insertion groove 193 coincide with each other. The stopper portion 195 starts at the top of the insertion hole 193 and is semicircular along the top of the locking member 192. It is configured to protrude into.

Next, the operation of the pump assembly equipped with the locking means according to the present invention configured as described above and the effects thereof will be described with reference to FIGS. 6 to 9.

First, the locking member 192 is positioned so that the stopper portion 195 of the locking member 192 is brought into contact with the inner locking jaw 191 so that the inner locking jaw 191 coincides with the insertion groove 193. (See Figure 6).

When the user presses the pushbutton 130 in this state, as shown in FIG. 7, while the inner-locking jaw 191 is accommodated in the insertion groove 193, the pushbutton 130 is together with the hollow piston 140. It is lowered, and the coil spring 170 is compressed. Therefore, the hollow piston 140 and the piston 181 are lowered together to pressurize the contents A of the pressure chamber 121, and thus the contents A filled in the pressure chamber 121 of the cylinder 120 are hollow pistons. 140, the communication path 183 is discharged to the outside through the outlet 131. At this time, when the pushbutton 130 is lowered to the maximum, the locking member 192 is forcibly fitted into the pushbutton 130 by the plurality of locking protrusions 194 and coupled thereto.

When the pushbutton 130 is released, as shown in FIG. 8, the pushbutton 130 and the hollow piston 140 are gradually raised by the restoring force of the coil spring 170, and the vacuum pressure in the pressure chamber 121 is increased. This takes Accordingly, the ball valve 160 rises upward due to the pressure difference between the pressure chamber 121 and the inside of the liquid container 30, and a part of the contents A in the liquid container 30 is pressurized through the suction hose 150. It is sucked into the chamber 121. When the locking member 192 moves integrally when the pushbutton 130 is lifted, the locking state of the pushbutton 130 is completely released. Therefore, in the unlocking state, the pushbutton 130 may be continuously pressed to continuously pump the contents A stored in the liquid container 30.

On the other hand, in the unlocked state, the outer cap 115 of the cap unit 110 is free to move in the axial direction by the height of the rotation and the receiving groove 118 from the inner cap 111 (see Fig. 5). Therefore, the neck of the liquid container 30 is not limited to the cap unit 110 unless the inner-ratchet protrusion 112 and the outer-ratchet protrusion 117 are firmly pressed while the outer cap 115 is pressed down while turning it. Can not open from (31).

In addition, as shown in FIG. 9, after the user finishes using the device, the locking member 192 accommodated in the pushbutton 130 is pulled down (see arrow direction in FIG. 9). And when the locking member 192 is turned so that the inner-locking jaw 191 and the insertion groove 193 do not coincide (see FIG. 2), the inner-locking jaw 191 is caught on the upper surface of the locking member 192. In this state, even if the user presses the pushbutton 130, it is caught by the locking member 192 and cannot be lowered. As a result, the lowering operation of the push button 130 is not made by the locking member 192, and thus the contents are not discharged.

As a result, the lowering operation of the push button 130 can be selectively prevented through the locking member 192, so that the contents contained in the container do not leak (aka, leakage) when the product is distributed or carried. It can be higher. In addition, since the locking member 192 is rotatably disposed from the top to the top of the cap unit 110, there is an advantage of easy operation thereof.

In addition, when the push button 130 is repeatedly pressed, since the locking member 192 is forcibly coupled to the push button 130 and interlocks with each other, the inconvenience of use by the locking member 192 is continuously. none.

In addition, in the state in which the pushbutton 130 is locked through the locking member 192, the outer cap 115 of the cap unit 110 is limited in rotation and movement in the axial direction. That is, as shown in Figure 2, the outer cap 115 is pressed by the locking member 192, the outer-ratchet protrusion 117 and the inner-ratchet protrusion 112 is maintained in a state of being engaged, thereby In the locked state of the push button 130, the outer cap 115 and the inner cap 111 are integrated.

This is to fill the contents (A) in the liquid container 30 and then rotate the outer cap 115 of the cap unit 110 through the automation line the inner cap 111 of the neck 31 of the liquid container (30). This is for easy tightening. As a result of applying the present invention to the existing liquid contents filling automation line, the test assembly was easily rotated to the inner cap 111 through the outer cap 115 and the pump assembly 100 to the neck 31 of the liquid container 30. It can be seen that can be easily mounted.

As described in detail above, according to the pump assembly for a liquid container having a locking means according to the present invention; The lowering operation of the pushbutton is allowed or restricted depending on whether or not the locking member is rotated by the locking member.

As a result, when the pushbutton is lowered by the locking member (push-button locking state), even if an external force is applied to the pushbutton during product distribution or portability, there is an effect of preventing the contents from leaking. In addition, locking the pushbutton through the locking member has the advantage that children with insufficient attention cannot operate the pushbutton without permission.

And because the locking member is disposed between the cap unit and the pushbutton to operate in an assembled state, there is no risk of loss, and there is an advantage of convenient operation.

In addition, when the locking state of the pushbutton is released, the outer cap constituting the cap unit is allowed to rotate and move axially from the inner cap, which makes it impossible for a child who lacks attention to open the cap unit from the neck of the container. There is this.
