Description

Container coupled type pump device {Container coupled type pump device}

The present invention relates to a pump device combined with a contents storage container, which is used in combination with a cap-joining portion of various containers storing contents, and which enables the contents of the container to be easily discharged through a pumping operation with a simple structure.

A pump or dispenser, which is generally attached to the top of a container storing contents such as cosmetics, perfume, medicine or food, discharges a certain amount of the contents for use by pumping them by pressing the button at the top downward.

These conventional pumps or dispensers were mainly used for containers made of hard materials.

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

Flexible containers like this have the effect of reducing costs because they are used by directly pouring out the contents by combining a cap instead of a pump or dispenser, or by refilling the contents into a container combined with a pump or dispenser, but they are very inconvenient to use.

In order to solve such a problem, a pump or dispenser combined with a flexible container has been disclosed, which has a structure in which a bellows is combined on the upper part of a base as in Patent Publication No. 10-2012-006523, and the bellows is pressed to pump and discharge the contents. However, this has the problems of being difficult to mold and manufacture because the base is formed as an integral structure, poor airtightness and weak control of the opening and closing of the contents supply section, resulting in a low contents discharge output, difficulty in operation because only the upper part of the bellows is pressed to perform the pumping operation, and low pumping power. In addition, since the bellows is pressed and restored by its own elasticity, the pumping operation power is low.

Above all, when using a flexible container for general purposes, there was a problem that it was inconvenient to use it for general purposes when combining it with the cap joint in the general purpose container.

Publication Patent No. 10-2012-006523 (January 18, 2012) Utility Model Registration No. 20-0391021 (July 19, 2005)

The present invention has been made to solve various problems of the above-mentioned prior art, and its purpose is to enable the contents of the container to be easily and effectively discharged by using a pumping operation that presses up and down while being combined with the cap-joining portion of various containers in which contents are stored.

The purpose of the present invention is to provide excellent manufacturing productivity by enabling simple and sturdy assembly manufacturing through a simple assembly structure.

According to the present invention, the ring-shaped connecting portions of the upper and lower covers are characterized by having a close-fitting press portion that close-fits and presses the rim of a dome-shaped body, a connecting rib that extends vertically outside the close-fitting press portion and forms a catch projection on the inside, and a catch projection that catches the catch projection of the connecting rib, which are installed facing each other vertically, and the connecting rib and the catch projection are installed facing each other so as to be staggered from both sides so as to be configured to perform one-touch connecting up and down.

According to the present invention, the sealing portions of the upper and lower covers are configured to form sealing projections protruding to pressurize and seal the edges of the upper and lower bellows, and sealing projections are formed protruding between the edges of the upper and lower bellows at opposing positions to form an airtight connection.

According to the present invention, front and rear coupling step portions are protrudedly formed on the outer sides of the output side assembly portion and the input side assembly portion of the upper and lower covers, a front insertion coupling portion into which the front coupling step portion is inserted is formed at the rear of the nozzle, and a rear insertion coupling portion into which the rear coupling step portion is inserted is formed at the front of the container coupling cap portion, and a sealing protrusion and a sealing groove are formed correspondingly in a ring-shaped structure on the outer periphery of the front and rear coupling step portion and the front and rear insertion coupling portion.

This invention inserts a check valve forward and backward inside the upper and lower bellows of a dome-shaped structure, a buffer spring into the central chamber, and then connects the upper and lower covers together, and a nozzle is connected to the front of the upper and lower covers, and a cap part for combining a container is connected to the rear, so that the contents are simply connected to the cap-combining portion of various containers in which the contents are stored by the cap part to discharge the contents.

That is, the purpose is to pump the contents inside the container by pressing the upper and lower bellows up and down to operate the pumping, together with the opening operation of the check valve, so that the contents can be discharged easily and effectively.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

The contents storage container combined pump device of the present invention is configured, as shown in FIGS. 1 to 12, to include upper and lower bellows (10) (10'), a buffer spring (20), front and rear check valves (30) (40), upper and lower covers (50) (50'), a nozzle (60), and a cap portion (70) for container combination, and is configured to be combined with a cap combination portion of a container in which various contents are stored and to discharge the contents by a pumping operation.

The upper and lower bellows (10)(10') above are configured to be formed facing each other with a flexible material such as rubber. That is, a chamber (15) is formed inside a dome-shaped body (11) forming a dome-shaped structure, and front and rear valve assembly parts (12)(13) having valve installation grooves (12a)(13a) formed inwardly at the front and rear of the dome-shaped body are formed to protrude, and an outlet hole (12c) and an inlet hole (13c) are connected between the chamber and the front and rear valve installation grooves to press the upper and lower pressing parts (16)(16') of the dome-shaped body up and down to perform a pumping operation.

At this time, unlike the rear valve assembly (13), the outer periphery of the front valve assembly (12) is configured to further form a fitting groove (12b).

The above buffer spring (20) is installed vertically in the chamber (15) of the upper and lower bellows (10)(10') so that when the upper and lower pressing parts (16)(16') of the upper and lower bellows are pressed up and down, the springy buffering operation is performed and the upper and lower pressing parts are returned to their original positions.

The above front and rear check valves (30)(40) are installed by insertion into the valve installation grooves (12a)(13a) of the upper and lower bellows so as to open the outlet hole (12c) and the inlet hole (13c) when the upper and lower bellows (10)(10') are pumping.

The above front and rear check valves (30)(40) are configured to open and close by moving back and forth according to pressure changes by connecting an opening/closing valve (32)(42) to the center of the support body (31)(41).

The upper and lower covers (50)(50') are configured to be joined to the upper and lower bellows at the top and bottom, and to be airtightly joined by pressing the edges (18)(18') of the dome-shaped body, and to be formed by a discharge-side assembly part (55) and an inlet-side assembly part (56) having assembly grooves (55a)(56a) into which front and rear valve assembly parts (12)(13) are inserted.

In particular, the ring-shaped connecting portions (51)(51') of the upper and lower covers are configured to have a close pressing portion (52) that presses the edge (18)(18') of the dome-shaped body, a connecting rib (53) that extends vertically outside the close pressing portion and forms a catch projection (53a) on the inside, and a catch protrusion (54) that catches the catch projection (53) of the connecting rib, so that the connecting rib and the catch protrusion are installed facing each other so as to be staggered from both sides, so as to enable one-touch connecting up and down.

That is, the connecting ribs and the catch structures are formed facing each other in an up-down manner so as to be staggered on both sides of the center line connecting the discharge-side assembly part and the inlet-side assembly part of the ring-shaped connecting part (51)(51') so as to enable one-touch connecting up and down.

A sealing projection (52a) is formed protrudingly on the sealing pressurizing portion (52) of the upper and lower covers (50)(50') to pressurize and seal the edges (18)(18') of the upper and lower bellows, and a sealing projection (18a)(18'a) is formed protrudingly in an opposing position between the edges (18)(18') of the upper and lower bellows to form an airtight connection.

The above nozzle (60) is inserted and connected to a front coupling step (57) formed with a step in front of the discharge side assembly of the upper and lower covers (50) (50'), and the container coupling cap (70) is inserted and connected to a rear coupling step (58) formed with a step in the rear of the input side assembly of the upper and lower covers (50) (50').

At this time, a front insertion joint (62) into which a front coupling step (57) is inserted is formed at the rear of the nozzle (60), and a rear insertion joint (72) into which a rear coupling step (58) is inserted is formed at the front of the container coupling cap (70), and a sealing projection (57a) (58a) and a sealing groove (62a) (72a) are formed in a ring-shaped structure corresponding to the outer periphery of the front and rear coupling step (57) (58) and the front and rear insertion joint (62) (72).

In addition, the center of the cap portion (70) for combining the containers is configured to have a contents supply hole (75) penetrating through it.

And, as shown in the drawing, the cap part (70) for combining the container can be configured to be combined by a spiral part (73) inside to a cap combining part to which a cap of a content storage container, such as a pouch container, is combined, or by other combining methods.

As a non-descript symbol, 55b represents a fitting projection into which a fitting groove (12b) of the outer periphery of the front valve assembly (12) is fitted into an assembly groove (55a) of the discharge side assembly into which the front valve assembly (12) is inserted, and 80 represents a sealing ring coupled to the inside of the cap portion (70).

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

First, the assembly process of the device of the present invention will be explained. As shown in Fig. 5, the buffer spring (20) is inserted into the chamber (15) of the upper and lower bellows (10) (10') and the front and rear check valves (30) (40) are assembled into the valve installation grooves (12a) (13a) of the front and rear valve assemblies (12) (13).

In this state, the upper and lower covers (50)(50') are connected above and below the upper and lower bellows (10)(10') (see Fig. 6).

This is because the upper and lower covers are assembled by inserting the front and rear valve assemblies (12) (13) into the assembly grooves (55a) (56a) on the inside of the discharge-side assembly (55) and the inlet-side assembly (56) while the close pressure portion (52) of the ring-shaped joint (51) (51') presses the edge (18) (18') of the dome-shaped body up and down.

At this time, the upper and lower bellows edges (18)(18') are sealed and hermetically joined by the contact projections (18a)(18'a) that are positioned opposite each other between the edges, and the upper and lower portions of the edges (18)(18') are sealed and hermetically joined by the contact projections (52a) that are protruded from the contact pressure portions (52) of the upper and lower covers (50)(50').

At the same time as assembling in this manner, the engaging projection (53a) of the engaging rib (53) extending vertically to the outside of the close-fitting pressurizing portion (52) in the ring-shaped joint (51)(51') engages with the engaging projection (54), but the engaging rib and the engaging projection are installed oppositely so as to be staggered from each other on both sides, so that they are interlocked with each other by one-touch joining up and down.

In this way, the upper and lower bellows (10)(10'), the buffer spring (20), and the front and rear check valves (30)(40) are assembled by the upper and lower covers (50)(50).

In this state, the nozzle (60) and the cap part (70) for combining the container are assembled at the front and rear of the upper and lower covers (see Fig. 7).

This is done by inserting the front coupling step (57) in front of the upper and lower covers (50) (50') into the front insertion coupling portion (62) in the rear of the nozzle, and inserting the rear coupling step (58) in the rear of the upper and lower covers (50) (50') into the rear insertion coupling portion (72) in front of the cap portion for combining the container, thereby coupling, and the sealing projections (57a) (58a) and the sealing grooves (62a) (72a) which are formed in a ring-shaped structure corresponding to the outer periphery of the front and rear coupling step portions (57) (58) and the front and rear insertion coupling portions (62) (72) are coupled to prevent separation by interlocking with each other.

In this way, the pump device of the present invention is assembled.

The pump device of the present invention assembled in this manner is installed by being coupled to a cap coupling portion (110) of a container storing various contents, for example, a pouch container (100), by a cap coupling portion (70) as shown in FIGS. 11 and 12.

In this state, the pouch container (100) is placed at the top and the pump device is positioned at the bottom, and the contents inside the pouch container are discharged by the pumping operation.

To explain this more specifically, the upper and lower pressing parts (16)(16') are pressed up and down at the upper and lower parts of the dome-shaped body (11) of the upper and lower bellows (10)(10') to perform a pumping operation.

In this way, when the upper and lower pressing parts (16)(16') are pressed, the buffer springs (20) installed up and down in the chamber (15) inside the dome-shaped body are compressed and then return to their original positions up and down, thereby performing a pumping operation.

By this pumping operation, the front and rear check valves (30) (40) inserted and installed in the valve installation grooves (12a) (13a) formed inside the front and rear valve assemblies (12) (13) of the upper and lower bellows (10) (10) open the outlet hole (12c) and the inlet hole (13c) due to the change in internal pressure.

By this operation, the contents inside the pouch container (100) are discharged and used through the contents supply hole (75) - inlet hole (13c) - chamber (15) - outlet hole (12c) - nozzle (70) of the container combining cap part (70).

In this way, the contents inside the pouch container are quantitatively discharged and used by one pumping operation of pressing the upper and lower pressing parts (16)(16') of the upper and lower bellows (10)(10') up and down.

In particular, the upper and lower pressing parts (16)(16') of the upper and lower bellows (10)(10') are not pressed from the top or bottom in a button-like manner as in the past, but are pressed from the top and bottom and returned by a buffer spring, thereby providing excellent pumping power and more effectively discharging and using the contents inside the pouch container.

Therefore, the present invention is a simple assembly structure in which a check valve is inserted forward and backward inside the upper and lower bellows of a dome-shaped structure, a buffer spring is inserted into the central chamber, and then the upper and lower covers (50)(50') are connected upward and downward, and a nozzle is connected to the front of the upper and lower covers, and a cap for container connection is connected to the rear, so that not only is the manufacturing productivity excellent, but also the assembly sturdiness and airtightness are excellent, and in particular, when used in combination with the cap connection portion of various containers in which contents are stored, the upper and lower pressing portions of the upper and lower bellows are pressed upward and downward, and the buffer spring is buffered and pumped to effectively discharge the contents inside the container together with the opening operation of the check valve.
