Description

Technology Field

[0001] The present invention relates to a pump device coupled to a liquid contents storage container, and more specifically, to a pump device coupled to a liquid contents storage container that is coupled to the cap coupling part of various containers in which liquid contents are stored, installed upside down so as to face downward, and conveniently discharges liquid contents through pumping operation by a simple structure. Background Technology

[0003] Generally, a pump or dispenser attached to the top of a container in which contents such as cosmetics, perfumes, medicines, or food are stored is designed to dispense a certain amount of contents for use by a pumping operation that pressurizes the top button downwards.

[0004] These conventional pumps or dispensers were mainly applied and used in containers made of hard materials.

[0005] However, recently, in addition to containers made of hard materials, the use of flexible containers such as vinyl pouches is increasing.

[0006] Since such flexible containers were used by combining a cap instead of a pump or dispenser to directly dispense the contents, or by refilling the contents into a container combined with a pump or dispenser, there was a cost-saving effect but there was a significant inconvenience in use.

[0007] In order to solve such problems, a pump or dispenser used in combination with a flexible container has been disclosed. This is structured such that a bellows is combined with the upper part of a base as in Public Patent No. 10-2012-006523, and the contents are discharged by pumping the bellows by pressing them. However, this has problems such as difficulty in molding manufacturing because the base is formed as a single unit, poor airtightness and weak control of opening and closing the contents supply section resulting in reduced contents discharge power, difficulty in operation and reduced pumping power because only the upper part of the bellows is pressed to pump, and reduced pumping power because the bellows is compressed and restored by its own elasticity.

[0008] Above all, when the above-mentioned flexible container is used for general purposes, there was a problem of some inconvenience in using it while connecting to the cap joint of the general-purpose flexible container. Prior art literature

[0023] Hereinafter, preferred embodiments of the present invention described above will be examined in detail with reference to the accompanying drawings.

[0024] As shown in FIGS. 1 to 10, the liquid contents storage container combined pump device of the present invention is configured to consist of a pump body (10), a buffer spring (20), upper and lower bellows (30)(30'), front and rear check valves (40)(40'), a nozzle (50), and a cap part (60) for container combination, and is configured to discharge the liquid contents downward by pumping operation while connected to the cap combination part (3) at the bottom of the contents storage container (2) where the liquid contents are stored.

[0025] The above pump body (10) is configured to form a chamber (11) that penetrates vertically inside, and front and rear valve assembly parts (12)(13) in which internal valve installation grooves (12a)(13a) penetrate and connect to the chamber (11), inlet hole (14a), and outlet hole (14b) at the front and rear centers.

[0026] In addition, support protrusions (11a) are formed protruding at equal positions on the inner circumference of the chamber (11), and the upper and lower ends of the support protrusions are configured to form round curved surfaces.

[0027] In addition, ring-shaped upper and lower coupling grooves (15) and (16) are formed facing each other on the outer side of the chamber (11) on the upper and lower parts of the pump body, and are configured so that a locking projection (15a) and (16b) are formed protruding at an equal position on the inner circumference of the upper and lower coupling grooves.

[0028] The above buffer spring (20) is inserted and installed inside the chamber (11) of the pump body to buffer up and down, and is configured to be inserted and installed so as to be supported by a support projection (11a) formed on the circumference of the chamber to prevent movement.

[0029] The upper and lower bellows (30)(30') are formed from a flexible material, such as rubber, so as to be sealed and connected to the upper and lower parts of the pump body, but are curved and protruded in opposite directions so as to be pumped by elastic pressure and return operation by an inner cushioning spring.

[0030] At this time, a connecting step (31)(31') is formed on the outer circumference of the upper and lower bellows and inserted into the upper and lower connecting grooves (15)(16), and the upper and lower fixing ring bodies (35)(35') are connected to the outside of the connecting step to fix the upper and lower bellows, and a ring-shaped locking groove (36) is formed on the outside of the upper and lower fixing ring bodies to be inserted into and fixedly connected to the locking projections (15a)(16a) of the upper and lower connecting grooves (15)(16).

[0031] The above front and rear check valves (40)(40') are formed with an inner blocking plate that can move back and forth in a disc-shaped structure, and are installed by inserting them into the valve installation grooves (12a)(13a) of the front and rear valve assembly so that when the upper and lower bellows are pumped, the blocking plate opens the inlet port (14a) and the outlet port (14b) due to pressure changes.

[0032] The nozzle (60) is connected to the front valve assembly (12) of the pump body, and the container connection cap (60) is configured to be connected to the rear valve assembly (13) of the pump body.

[0033] At this time, the nozzle (50) is configured to form a ring-shaped coupling groove (51) at the rear to insert and connect the ring-shaped coupling protrusion (12b) of the front valve assembly (12), and a ring-shaped coupling protrusion (71) and a ring-shaped coupling groove (72) are formed correspondingly on the ring-shaped coupling groove and the ring-shaped coupling protrusion to prevent detachment, and the container coupling cap (60) is configured to form a ring-shaped coupling groove (61) at the front to insert and connect the ring-shaped coupling protrusion (13b) of the rear valve assembly (13), and a ring-shaped coupling protrusion (71) and a ring-shaped coupling groove (72) are formed correspondingly on the ring-shaped coupling groove and the ring-shaped coupling protrusion to prevent detachment.

[0034] And, the rear of the nozzle (50) and the front of the cap part (60) for container coupling are configured to press and fix the outer circumference of the front and rear check valves (40)(40'), the inner end of which is inserted into the valve installation groove (12a)(13a) of the front and rear valve assembly part.

[0035] As an unexplained symbol, 65 represents a spiral hole for spiraling to the cap coupling portion of a container for container coupling with the cap coupling portion of a container for storing contents.

[0037] Next, we will examine the operation and function of the present invention configured as described above.

[0038] First, the assembly process of the pump device of the present invention is described as follows: as shown in FIGS. 6 and 7, a cushioning spring (20) is inserted vertically into a chamber (11) formed vertically through the inside of the pump body (10), and upper and lower bellows (30) (30') are sealedly connected to the upper and lower parts of the pump body (10).

[0039] At this time, the upper and lower bellows (30)(30') are connected such that the connecting step (31)(31') formed on the outer circumference is inserted into the upper and lower connecting grooves (15)(16) formed in a ring shape on the upper and lower parts of the pump body, and the upper and lower fixing ring body (35)(35') is inserted and connected above the connecting step. Since the ring-shaped locking groove (36) formed on the outer circumference of the upper and lower fixing ring body is inserted into the locking projection (15a)(16a) formed at an equal position on the inner circumference of the upper and lower connecting grooves, the upper and lower bellows are fixedly connected while being pressed, thereby having a simple connection method and excellent sealing power of the upper and lower bellows.

[0040] In this state, front and rear check valves (40) (40') are inserted into the valve installation grooves (12a) (13a) inside the front and rear valve assembly parts (12) (13) formed at the front and rear of the pump body, respectively, and a nozzle (50) is assembled to be attached to the front valve assembly part (12), and a container coupling cap part (60) is assembled to be attached to the rear valve assembly part (13).

[0041] At this time, the ring-shaped coupling grooves (51)(61) formed at the rear of the nozzle (50) and the front of the cap portion (60) for container coupling are respectively inserted and coupled to the ring-shaped coupling protrusions (12b)(13b) of the front and rear valve assembly portions (12)(13), and are coupled so as to prevent detachment by means of the corresponding ring-shaped coupling protrusions (71) and ring-shaped coupling grooves (72) formed on the ring-shaped coupling grooves and ring-shaped coupling protrusions.

[0042] In this way, the pump device of the present invention is assembled (see FIG. 4).

[0043] The pump device of the present invention, assembled in this manner, is connected to the cap connection portion (3) at the bottom of the contents storage container (2) where liquid contents are stored by the container connection cap portion (60) as shown in FIGS. 9 and 10, and is installed and used by hanging the liquid contents storage container upside down.

[0044] In this installed state, the liquid contents stored in the contents storage container (2) are discharged and used by pumping operation by the pump device of the present invention.

[0045] To explain this more specifically, the upper and lower bellows (30)(30') that are sealed and connected to the upper and lower parts of the pump (10) are pressed in opposite directions to operate the pumping.

[0046] At this time, the upper and lower bellows (30)(30') are elastically supported vertically by a cushioning spring (20) that is inserted vertically into the chamber (11) of the pump body. Therefore, when the upper and lower bellows are pumped vertically, the upper and lower bellows return to their original positions facing each other after being compressed vertically by the compression and restoration operation of the compression spring, thereby effectively pumping.

[0047] In this way, the front and rear check valves (40) (40,) assembled inside the front and rear valve assembly (12) (13) of the pump body are operated by the pumping operation of the upper and lower bellows to open the inlet port (14a) and outlet port (14b) connecting the front and rear valve assembly and the chamber (11) due to changes in internal pressure.

[0048] By such opening operation, the liquid contents inside the contents storage container (2) are discharged through the container coupling cap part (60) - rear valve assembly part (13) - inlet port (14a) - chamber (11) - outlet port (14b) - front valve assembly part (12) - nozzle (50).

[0049] In this way, the liquid contents inside the contents storage container are dispensed in a precise amount by a pumping operation that presses the upper and lower bellows (30)(30') up and down.

[0050] In particular, the upper and lower bellows (30)(30') are not pressed from the top or bottom in a button-like manner as in the conventional method, but are pressed from the top and bottom in opposite directions and are springed back by a cushioning spring to further maximize the pumping force, thereby allowing the liquid contents of the contents storage container to be discharged and used more effectively.

[0051] Accordingly, the present invention allows for the convenient and effective discharge of liquid contents by connecting upper and lower bellows (30)(30') to the upper and lower parts of a pump body (10) in which a cushioning spring is inserted and installed vertically, and connecting front and rear check valves (40)(40') and a nozzle (50) and a cap part (60) for container connection to the front and rear parts of the pump body, and simply connecting them to the cap connection part at the bottom of a contents storage container in which liquid contents are stored, thereby opening the front and rear check valves and discharging the liquid contents inside the contents storage container downwards through a pumping operation that presses the upper and lower bellows vertically.
