The present invention further relates to a dispenser type liquid pouch container that is designed having self-standing means that can cooperate with the folding and unfolding of a pouch body.

BACKGROUND ART Generally, liquid contents such as detergent, cleaning material, and medicinal liquid are packaged, delivered and sold in a state where they are contained in a variety of containers.

Conventional containers for holding the liquid contents is formed of synthetic resin with a closure coupled therewith. After the closure is

opened, a pump dispenser is assembled on the container to easily dispense the contents.

For example, U. S. Patent No. 5,579, 945 discloses a dispenser type pouch container that is designed such that a closure of a spout is first removed and then a dispenser assembly is assembled on the spout.

Although the container of this patent is formed of pouch considering the environmental problem, a special spout has to be attached on the upper end of the pouch container to assemble the dispenser assembly thereon. Furthermore, since the pouch container has not self-standing force resisting against the pumping force of the dispenser, the pouch container should be assembled on a specially prepared rigid case. Such a case is specially designed for the special pouch container, not being compatible to the pouch container produced by other companies.

Korean Utility-Model Application No. 1999-16315 discloses a structure that is designed such that a pump dispenser assembly is directly attached on a pouch, not needing a special spout.

However, such a structure still requires a rigid case for supporting the pumping force of the pump dispenser. In addition, when

the pouch container is inclined at a predetermined angle during its use, the pouch may be folded, making it difficult to allow the contents to be normally poured out of the container.

In addition, when the case is not provided with a hole at its predetermined location, since the pouch disposed therein is not contracted, it cannot be used for the vacuum pouch.

DISCLOSURE OF INVENTION Therefore, the present invention has been made in an effort to solve the above-described problems of the prior art.

It is an objective of the present invention to provide a dispenser type liquid pouch container that is provided with self-standing dispensing means that allows the liquid holding pouch to maintain its self-standing force without a specially provided rigidity case or container, thereby making it possible to maintain the standing force even when force is applied to a pump dispenser.

It is another objective of the present invention to provide a dispenser type liquid pouch container that has self-standing means that can be folded and unfolded in association with the folding and unfolding

operation of a pouch body.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described more in detail hereinafter in conjunction with the accompanying drawings.

EMBODIMENT 1 FIGS. 1 and 2 show a dispenser type liquid pouch container according to a first embodiment of the present invention.

In this embodiment, a pouch container having a pump dispenser 100 is designed to maintain its standing force even when depressing force is applied to a button 102 of the pump dispenser 100.

That is, the inventive pouch container comprises a pouch main body 200, a pump dispenser 100 coupled on a spouting portion 202 of the pouch main body 200, and self-standing maintaining means 300 disposed between the spouting portion 106 and a bottom of the pouch main body 200.

Generally, contents are filled in the pouch main body 200 in a state where the body 200 is folded to be compact as shown in FIG. 2.

After the contents are filled in the pouch main body 200, the pump dispenser 100 is assembled on the spouting portion 202.

The pump dispenser 100 is a conventional one that is designed to dispense the contents by depressing the button 102, the detailed description of which will be omitted herein.

As a feature of the present invention, self-standing maintaining means 300 is disposed between an outlet of a lower housing 104 of the pump dispenser 100 and the bottom 204 of the pouch main body 200.

The self-standing maintaining means 300 comprises a spouting member 302 having an upper end inserted into the outlet 106 of the lower housing 104 of the pump dispenser 100 and a lower end closely contact the bottom 204 of the pouch main body 200.

The spouting member 302 is designed having a length extending closely to the bottom 204 when the pump dispenser 100 is coupled on the spouting portion 202 of the pouch main body 200. The spouting member 302 is provided with a hollow portion 304 communicating with the outlet 106 of the lower housing 104 of the pump dispenser 100.

The spouting member 302 is further provided at its lower end with a bottom spouting hole 306 communicating with the inner space of the pouch main body 200.

Preferably, a support portion 308 for preventing the bottom 204 of the pouch main body 200 from being damaged is formed on the lower end of the spouting member 302.

The support member 308 can be integrally formed with the lower end of the spouting member 302 or be assembled with the lower end after it is separately prepared.

For example, FIGS. 3 and 4 show a foldable support member 310 separately prepared.

The support member 310 comprises an assembling part 312 for assembling on the spouting member 302 and folding support parts 314 extending horizontally from the lower end of the assembling part 312 to

enhance the self-standing force. Each of the folding support parts 314 is connected to each other by articulation parts 316 for allowing the folding operation.

An assembling projection 318 is provided on each of the folding support parts 314 for maintaining the horizontally disposed state of the folding support parts 314.

The assembling projections 318 can be formed in a variety of examples that can prevent the folding support parts 314 from returning to their initial positions. As an example, the assembling projection 318 shown in a dotted line is tightly fitted on an inner wall of the assembling part 312 when the folding support part 314 is horizontally widened, thereby preventing the folding support part 314 from returning to its initial positions.

As shown in FIG. 5, the support member 310 has plural folding support parts 314 disposed at an identical distance from each other, and the spouting hole 306 communicating with the spouting member 302 can be formed between the folding support parts 314.

In addition, the self-standing maintaining means 300 of the present invention may further comprise reinforcing means 400 disposed

on the bottom 204 of the pouch main body 200.

The reinforcing means 400 comprises a base for supporting the pouch main body 200. The base 402 comprises a center base disposed under the spouting member and a sub-base disposed on a periphery of the bottom 204 of the pouch main body 200.

The reinforcing means 400 is attached on the bottom portion of the pouch main body 200, and is made of hard material in consideration of the structural stability. However, when the reinforcing means 400 is made of a hard material, it may disturb the folding operation of the pouch main body 200. Therefore, a bending portion 404 can be formed on the folding portion. The bending portion 404 is defined by a groove formed on the reinforcing means.

In addition, as shown in FIG. 6, a portion of the bottom 204 is cut away and an attaching portion 406 can be formed so that a portion of a wall of the pouch main body 200 can be directly attached on the reinforcing means 400, thereby improving the attaching force of the pouch main body 200 to the reinforcing means 400.

Meanwhile, the spouting member 302 of the present invention can be designed having the spouting hole defined by removing a sidewall

of the spouting member 302. However, at this point, a specially prepared spouting tube may be assembled on the outlet 106 of the housing 104.

The operation of the above described dispenser type liquid pouch container will be described hereinafter.

A final product is completed by filling contents into the pouch main body and assembling the pump dispenser 100 on the spouting portion 202.

Then, the user depresses the button 102 of the pump dispenser 100 to dispense the contents out of the pouch main body. At this point, the pouch main body 200 is applied with depressing force.

However, the depressing force is firstly supported by the spouting member 302 disposed by the bottom 204 of the pouch main body 100 and the outlet 106 of the dispenser housing 104, whereby the standing force of the main body 200 is maintained by preventing the main body 200 from being folded.

That is, the self-standing means 300 prevents the main body from being structurally shrunken by resisting the depressing force applied to the button 102 of the pump dispenser 100.

In addition, the folding and shrink of the pouch main body is further prevented by the reinforcing means 400.

Here, as a feature of this embodiment, the self-standing support means 300 is designed to be reciprocally moved in cooperation with the folding and unfolding operation of the pouch main body 200.

That is, the self-standing support means 300 comprises an upper spouting member 320 coupled on the lower housing 104 of the pump dispenser 100, a lower spouting member 322 slidably inserted into the lower spouting member 322 and extending to the bottom 204 of the pouch main body 200.

The upper spouting member 320 may be supported on the spouting portion 202 of the pouch main body 200 by a separately

prepared support 326.

In this embodiment, the self-standing support means 300 is inserted and coupled on the lower end of the housing 104 when the pump dispenser is assembled on the spouting portion 202.

The operation of the above described pouch container will be described hereinafter.

A product is completed by filling contents in the pouch main body 200 and assembling the pump dispenser 100 on the spouting portion 202 as shown in FIG. 7.

Then, the user depresses the button 102 of the pump dispenser 100 to dispense the contents out of the pouch main body through the lower spouting hole 306.

At this point, the pouch main body 200 is applied with depressing force. However, the depressing force is firstly supported by the spouting member 302 disposed by the bottom 204 of the pouch main body 100 and the outlet 106 of the dispenser housing 104, whereby the standing force of the main body 200 is maintained by preventing the main body 200 from being folded.

Meanwhile, the self-standing support means 300 is designed to

vary its length as the upper and lower spouting members 320 and 322 are moved away or closely from and to each other in accordance with the folding and unfolding operation of the pouch main body 200.

Here, the spouting hole may be formed by cutting sidewalls of the upper and lower spouting members 320 and 322.
