Description

Fluid pump dispenser{A FLUID PUMP-DISPENSER}

The present invention relates to a fluid pump dispenser, and more specifically, by improving the structure of the cylinder, piston tube, and push button among the parts of the pump assembly that pumps and discharges the contents to the outside, the existing elasticity is reduced by the action of vacuum force in a reduced pressure state. A fluid pump that facilitates the discharge of contents without a spring, prevents contamination and loss of the packaging box due to discharge of contents, reduces logistics costs by minimizing height, and allows recycling by discharging with the container immediately after use. It's about the dispenser.

In general, a pump dispenser consists of a container made of synthetic resin that holds the contents of various liquids such as cleaning fluid and water, a pump assembly that fastens the mouth of the container with a cap to discharge the contents to the outside, and the contents contained inside the container. It consists of a tube that guides the pump assembly.

And the pump assembly includes a cylinder that accommodates a piston ring and a spring member that provides elastic restoring force, a sealing ring coupled to the top, and is mounted on the inlet of the container by the cap, and a spring member that is installed on the piston ring and the sealing ring. A push button consisting of a piston tube and a nozzle head with the bottom in contact with the top, and a ball valve that opens and closes the inlet of the cylinder are formed integrally with the bottom of the spring member.

Meanwhile, when the contents of various liquids such as cleaning liquid and water are placed in the container, and the pumping operation of pressing and releasing the push button of the pump assembly is repeated, the contents contained in the container flow into the cylinder, and then the contents inside the cylinder flow into the nozzle. It is discharged to the outside through the discharge pipe of the head, and the push button rises to its original state after being lowered with the help of the elastic force of the spring member to help the user's convenience.

However, the spring member, which is one of the main parts of the pump assembly, is oxidized by liquid detergent or cleaning fluid, which has a negative effect on the human body. In addition, this problem can be solved by using plastic containers for detergent or cleaning fluid discharged in large quantities in ordinary homes or public saunas. When disposing of the spring, the existing metal spring is molded into a synthetic resin material so that it can be immediately recycled without having to disassemble and separate it.

For example, Domestic Registered Utility Model No. 20-0286798, “Spring device molded from synthetic resin,” was proposed, which is hygienic as the spring material is molded from synthetic resin, and is convenient and recyclable because it is discharged together with the container rather than separated after disassembly. However, when distributing and storing a pump dispenser, if the push button is pressed and the contents leak out, the packaging box may be contaminated or the contents may be lost. To solve this problem, a method is used to lower the push button and fasten it to the cap. This caused a problem in that pumping efficiency was reduced because the synthetic resin spring was compressed over a long period of time and its elastic force was weakened.

In order to prevent weakening of elasticity due to compression of the synthetic resin spring, a stopper was installed to prevent the push button from descending.

For example, Domestic Registered Utility Model No. 20-0369051 "Pumping device for liquid container with moving stopper" and Registered Utility Model No. 20-0460772 "Pump container" were proposed, but these were simply attached to the connector to prevent the push button from lowering. A 'C' shaped clip-shaped stopper is provided separately to attach and detach, and when combined with the problem of it being lost after separation, the push button is in an elevated state, which increases the packaging and increases the manufacturing and logistics costs.

In addition, Domestic Registered Utility Model No. 20-0468344, “Pump head structure with a direction-variable rotating nozzle,” divides the nozzle through which the contents are discharged into a main body and a rotating part, and has shaft rods on both sides of the rotating part that rotates to open and close the passage. is formed to protrude, and a C-shaped receiving groove is formed in the main body so that the shaft rod of the rotating part can rotate after being inserted. However, the rotating part is not fixed in a vertical or horizontal state and rotates freely, so it is subject to pressure during pumping operation. It was inconvenient to use because there was a problem of it descending and closing the passage.

Domestic registered utility model No. 20-0286798 (announced on August 24, 2002) Domestic registered utility model No. 20-0369051 (announced on December 4, 2004) Domestic registered utility model No. 20-0460772 (announced on June 12, 2012) Domestic registered utility model No. 20-0468344 (announced on August 8, 2013)

Hereinafter, the present invention will be described in detail using the attached drawings. However, since the attached drawings show preferred embodiments of the present invention, the scope of the present invention is not limited by these drawings. In addition, even if the configuration is essential for carrying out the present invention, a detailed description of the configuration that belongs to the known technology or can be easily implemented by a person skilled in the art from the known technology will be omitted.

The pump dispenser of the present invention includes a container 100 that accommodates the contents as shown in Figures 1 to 3, and a pump that is fastened to the inlet 101 of the container 100 with a cap 200 to discharge the contents to the outside. A basic configuration consisting of an assembly (1) and a tube (300) that guides the contents to the pump assembly (1) is used.

And the pump assembly (1) accommodates a movable piston ring (10) inside, a sealing ring (11) is coupled to the top, and a cylinder (13) is mounted on the inlet (101) of the container (100) by the cap (200). ), and is inserted into the center of the movable piston ring 10 and the sealing ring 11, and the upper end is exposed to the outside of the cylinder 13, and the lower peripheral surface has an inclined protrusion 141 and an inlet 142 through which the contents pass. A push button having a nozzle head 15a formed at the tip of a piston tube 14 and an ejection port 15b through which the upper end of the piston tube 14 is fitted and discharges the contents moving upward along the internal passage to the outside. (15) And a valve 12 that opens and closes the inlet 131 formed in the cylinder 13 is included.

The pump dispenser of the present invention uses the above basic configuration, but improves the structure of the cylinder 13 and piston tube 14 among the parts of the pump assembly 1 that pumps and discharges the contents to the outside, thereby reducing pressure without the existing elastic spring. The structure of the push button (15) was improved to facilitate the discharge of the contents through the action of the vacuum force of the state, and to stably maintain the open or closed state of the passage of the outlet (15b), thereby preventing the discharge of the contents. The goal is to prevent contamination and loss of the box, reduce management and logistics costs by minimizing the height, and enable recycling by discharging it with the container 100 immediately after use.

Therefore, the pump assembly (1) facilitates discharge of the contents through the action of vacuum force in a reduced pressure state even without an elastic spring, prevents contamination and loss of the packaging box by preventing discharge of the contents, and minimizes the height of the cylinder. This is achieved by improving (13), piston tube (14), and push button (15).

To this end, as shown in FIGS. 1 to 4, in order to improve the structure that can generate vacuum force in a reduced pressure state, which acts as a conventional elastic spring, the cylinder 13 has a piston tube 14 and a movable piston ring 10. The inner tube (13a) and the outer tube (13b) are lowered so that the contents are moved upward along the inner passage of the piston tube (14) and delivered to the push button (15) so that a vacuum force can be applied in a depressurized state in the inner space. It is formed by dividing it into parts and they are fused or joined so that the parts that are fitted together can maintain airtightness.

And the inner tube (13a) fitted into the inner diameter of the outer tube (13b) of the cylinder (13) has a first receiving groove (132) in the partition wall formed in the horizontal and vertical directions on the upper side as shown in FIGS. 3 and 5. A fixed piston ring 16 is disposed in the first receiving groove 132 to be fitted and sealed around the circumferential surface of the piston tube 14, and a movable piston ring 10 is placed on the lower side of the first receiving groove 132. ) is made to provide a reduced pressure space (H) that is in a low pressure state when it descends together with the piston tube (14).

In addition, the fixed piston ring 16 in contact with the circumferential surface of the piston tube 14 and the movable piston ring 10 in contact with the inner diameter of the inner tube 14 move smoothly up and down while maintaining a sealed state as shown in FIG. 3. For this purpose, semicircular protrusions are formed protruding from the upper and lower sides, and the fixed piston ring 16 can be replaced with an O-ring 16a having a circular cross-section and an '○' shape as shown in FIG. 12. The movable piston ring 10 is formed as an arc-shaped curved portion 10a as shown in FIG. 13, and the semicircular protrusions protruding on the upper and lower sides can be formed as free ends to provide elastic force. Let it be revealed.

In addition, the outer tube (13b), which is fitted and coupled to the inner diameter of the inner tube (13a) of the cylinder (13), is closed at the top with a sealing ring (11) as shown in Figures 1 and 3, and is sealed by a cap (200). It is mounted on the inlet 101 of (100), and a second receiving groove 133 is formed at the lower part to accommodate the valve 12 that opens and closes the inlet 131 and moves up and down. A tube 300 that guides the contents contained in the container 100 is inserted into the lower side.

On the other hand, in order to cancel the depressurized space (H) created in the inner tube (13a) of the cylinder (13) to create a space at atmospheric pressure and stop the operation of returning to the raised state of the push button (15), as shown in FIGS. 1 and 1 As shown in 4, a control room 135 with a through hole 134 penetrating into the decompression space (H) is provided in a portion of the partition wall to form the first receiving groove 132 of the inner tube 13a. .

In addition, a control valve 2 is provided that can change the reduced pressure space H to atmospheric pressure or reduced pressure (vacuum) by opening and closing the through hole 134 of the control room 135.

As an example of the control valve 2, as shown in FIGS. 4 and 5, the lower end opens and closes the through hole 134 of the control room 135 and is a soft valve with a plurality of grooves formed in the vertical direction on the circumferential surface to serve as an air passage. It is formed by a stopper 211 and a gripping handle 212 with a lower side embedded in the stopper 211 in a locking shape and a locking piece 213 protruding from the upper side.

In addition, a part of the control chamber 135 formed in the inner tube 13a of the cylinder 13 is protruded upward to form a locking groove 136, and the locking groove 136 is provided with a handle for holding the control valve 2 ( When the locking piece 213 formed in 212 is seated, the stopper 211 maintains the open state of the through hole 134 of the control room 135, so that the decompression space (H) is at atmospheric pressure, and the push button 15 is activated. It is made to descend by its own weight.

Therefore, the pump assembly 1 of the above embodiment artificially lifts the control valve 2 as shown in FIG. 4 or seats the locking piece 213 of the handle 212 in the locking groove 136 on the upper side of the control chamber 135. When this is done, the stopper 211 opens the through hole 134 of the control room 135, so the reduced pressure space (H) created in the inner tube (13a) of the cylinder (13) is changed to a space at atmospheric pressure, and at the same time, the push button (15) The hypermovable piston ring 10 and piston tube 14 are lowered by their own weight and remain stationary as shown in FIG. 3, and in this state, pumping is impossible in an unused and packaged state, preventing discharge of the contents, so the packaging box It not only prevents contamination and loss of contents, but also reduces management and logistics costs by minimizing height. Since existing metal elastic springs are unnecessary, the contents can be immediately discharged with the container after use and recycled. There is this.

And on the contrary, the push button 15, the movable piston ring 10, and the piston tube 14 are raised as much as possible to the upper side of the inner tube 13a of the cylinder 13 as shown in FIG. 7 in a state where there is no decompression space H. As shown in FIG. 6, when the stopper 211 of the control valve 2 closes the through hole 134 of the control chamber 135 and the push button 15 is pressed as shown in FIG. 5, the movable piston ring 10 And as the piston tube (14) descends together, a reduced pressure space (H) in which a vacuum force is generated in a low pressure state is created in the inner tube (13a) of the cylinder (13). When the push button (15) that was being pressed is released, in FIG. As the movable piston ring 10 and the piston tube 14 rise together to their original state by the vacuum force, the contents of the container 100 enter the inside through the tube 300 and the inlet 131 of the external tube 13b. It is moved to the pipe (13a) and through a repeated process, the contents are discharged through the outlet (15b) of the push button (15) and introduced into the inner pipe (13a) as shown in FIG. 8, so that an elastic spring made of metal or synthetic resin is not required. There is an advantage that pumping is possible through the action of vacuum force under reduced pressure, and manufacturing cost and productivity are improved by reducing the quantity of parts.

Next, as another embodiment of the control valve 2 according to the present invention, as shown in FIG. 9, the shaft rod 214a opens and closes the through hole 134 of the control chamber 135 formed in the inner tube 13a of the cylinder 13. A spherical stopper 214 made of a soft or hard material so that it can be erected, a spring 215 made of synthetic resin that is inserted into the shaft rod 214a of the spherical stopper 214 and provides elastic force, and this spring 215 is supported. The fixing ring 216, which is fitted on the upper side of the control chamber 135 formed on the inner tube 13a of the cylinder 13, and the step formed on the upper end of the shaft rod 214a of the spherical stopper 214 are fitted and coupled to each other. A coupling hole 217 is formed in the center of the door, and a gripping handle 212a with a protruding locking piece 213 is provided on one side.

Then, a part of the upper part of the control chamber 135 is protruded to form a locking groove 136, and when the locking piece 213 formed on the gripping handle 212a of the control valve 2 is seated in the locking groove 136, the shaft seal As (214a) rises and the spring 215 is compressed, the spherical stopper 214 maintains the through hole 134 of the control chamber 135 in an open state.

Therefore, the control valve 2 of the embodiment of FIG. 9 is not operated by its own weight but by the elastic force of the spring 215 even when the spherical stopper 214 normally closes the through hole 134 of the control chamber 135. 5, 7 and 8, when the push button 15 is pressed, the piston ring 10 and the piston tube 14 descend together, creating a reduced pressure space (H) in which a vacuum force is generated in a low pressure state. When the pressurized push button 15 is released, the piston ring 10 and the piston tube 14 rise together to their original state due to the vacuum force generated in the decompression space H, and the contents of the container 100 are released into the tube. It is moved to the inner tube (13a) through the inlet (131) of (300) and the outer tube (13b), and in a repeated process, the contents are discharged through the outlet (15b) of the push button (15) and flow into the inner tube (13a). When the gripping handle 212a of the control valve 2 is raised and the locking piece 213 is seated in the locking groove 136 protruding from the upper side of the control room 135, the shaft rod 214a is raised and As the spring 215 is compressed, the spherical stopper 214 opens the through hole 134 of the control room 135 to maintain a space at atmospheric pressure rather than a decompression space (H), making pumping of the push button 15 impossible and the contents Since the discharge of is prevented, contamination of the packaging box and loss of contents can be prevented as well as management and logistics costs can be reduced by minimizing the height.

Next, as another embodiment of the control valve 2 according to the present invention, a valve formed on the inner tube 13a of the cylinder 13 as shown in FIG. 10 A stopper 211a on the lower side that opens and closes the through hole 134 of the control room 135, a male screw 218 partially cut in the vertical direction to allow air to move around the circumferential surface, and a grip handle 212b at the top are integrated. It is formed and the stopper 211a portion may be coated with soft rubber for airtightness.

And a female thread 137 is formed in the control chamber 135 formed in the inner tube 13a of the cylinder 13, and the male thread 137 is formed on the gripping handle 212b of the control valve 2 ( 218) is fastened so that the stopper 211a opens and closes the through hole 134 of the control room 135 through forward and reverse rotation.

Therefore, the control valve 2 of the embodiment of FIG. 10 rotates while the male screw 218 formed on the grip handle 212b is fastened to the female screw 137 of the control room 135, so that the stopper 211a is held in the control room ( 5, 7 and 8 in a state in which the through hole 134 of 135) is closed, when the push button 15 is pressed, the piston ring 10 and the piston tube 14 are lowered together and low pressure is generated. In this state, a reduced pressure space (H) in which a vacuum force is generated is created, and when the push button (15) that was being pressed is released, the piston ring (10) and the piston tube (14) are compressed by the vacuum force generated in the reduced pressure space (H). As it rises to its original state, the contents of the container 100 are moved to the inner tube 13a through the inlet 131 of the tube 300 and the outer tube 13b, and in a repeating process, the contents of the container 100 are moved to the outlet 15b of the push button 15. The furnace contents are discharged and introduced into the inner tube (13a), and the gripping handle (212b) of the control valve (2) is rotated in the opposite direction so that the male screw (218) is connected to the female screw (137) of the control chamber (135). As it rises according to the guidance, the stopper 211a opens the through hole 134 of the control room 135 to maintain a space at atmospheric pressure rather than a reduced pressure space (H), making pumping of the push button 15 impossible and discharging the contents. This has the advantage of preventing contamination of the packaging box and loss of contents, as well as reducing management and logistics costs by minimizing the height.

Next, as another embodiment of the control valve 2 according to the present invention, as shown in FIG. 11, the lower side opens and closes the through hole 134 of the control chamber 135 formed in the inner tube 13a of the cylinder 13. The stopper (211b), the locking ring (219) that is cut through in the vertical direction and protrudes from the circumferential surface to allow air to move, and the gripping handle (212c) at the top are all made of synthetic resin or hard rubber that is softer than hard. It is formed by molding.

In addition, a lower locking groove 138a and an upper locking groove 138b are formed in a spaced apart state inside the control chamber 135 formed in the inner tube 13a of the cylinder 13, and the lower locking groove 138a and the upper locking groove 138b are formed in a spaced apart state.
