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.

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.

FIG. 1 shows an embodiment of the present invention.

As shown in the drawings, the inventive dispenser type liquid pouch container is designed to be stable by its self-standing structure.

That is, the spout container maintains its self-standing structure even when a button of a pump dispenser 100 is pushed to dispense the content.

To this end, the liquid pouch container comprises a pouch main body 200 formed in a flexible material and self-standing dispensing means suspended between an outlet hole of a lower housing 104 of the pump dispenser 100 and a bottom 204 of the pouch main body 200.

Contents is filled in the pouch main body 200 and the pump dispenser 100 is coupled on an outlet of the pouch main body 200, whereby a product containing the liquid content is completed.

To provide the self-standing force to the flexible pouch main body 200, at lest two sealing portions 206 are formed crossing each other, by which the pouch main body 200 of the present invention is formed in a tetrahedron conical shape. As a result, it becomes possible that the pouch main body can be self-standing.

Furthermore, a reinforcing sealing portion is further provided connecting the both side sealing portions 206 disposed in a crossing direction with respect to each other. The structure of the pouch main body becomes more stable in its structure.

Preferably, in the present invention, the size of the bottom of the pouch main body 200 is designed to be greater than other portion to increase the structural stability thereof.

Meanwhile, the pump dispenser 100 of the present invention is a conventional piston cylinder type that is designed to dispense the stored content by generating vacuum pressure in the lower housing 104 as the button 102 is reciprocally operated. That is, the pump dispenser 100 is a general structure using a one-way valve to pour the content according to the pressure of the button 102, the detailed description of which will be omitted herein.

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

The self-standing spouting means 300 is provided to maintain the self-standing force even when the pump dispenser 100 is pressurized.

Since a lower end of the self-standing spouting means is supported on the bottom 204, even when the button 102 is pushed, the pushing pressure is applied to the pouch main body.

As an embodiment, the self-standing spouting means 300 comprises a spouting support 302 having an upper end communicatively inserted into an outlet of the lower housing 104 of the pump dispenser 100 and a lower end closely contacting the bottom o the pouch main body 200.

That is, the spouting support 302 is extended to the pump dispenser 100 coupled on the outlet 202 of the pouch main body to the bottom of the pouch main body 200. The spouting support 302 is hollowed to communicate with the outlet of the lower housing 104 of the pump dispenser 100. The spouting support 302 is further provided at

lower end with at least one bottom spout hole 304 so that the hollow portion can communicate with the inside of the main body 200.

Preferably, the lower end of the spouting support 302 is designed not to damage the bottom of the main body 200. Therefore, the lower end of the spouting support 302 is designed in a widened bottom surface or a specially designed support member made of a smooth material can be attached on the lower end of the spouting support 302.

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

First, a liquid product is made by filling the liquid in the pouch body and coupling the pump dispenser 100 on the outlet 202 of the pouch body.

Then, when a user depresses the button 102 of the pump dispenser 100, the liquid is poured out of the container. At this point, the pouch is subject to a predetermined pressure by the depressing force.

However, since the pouch main body 200 of the present invention has a stable structure and the spouting support 302 is disposed between the outlet of the lower housing 104 of the dispenser 100 and the bottom

204 of the pouch main body 100, it can be prevented that the pouch main body 200 is bent or folded, thereby maintaining the self-standing force.

FIGS. 2 to 6 show a variety of modified examples of the pouch main body.

As shown in the drawings, the pouch main body 200 has at least two sealing portions 206 disposed in a crossing direction with respect to each other. In addition, by varying the length and width of the sealing portion, a variety of shapes of the pouch main body can be realized.

For example, FIGS. 1 and 5 show a pouch main body having a triangular bottom in which three sides have an identical length. FIGS. 3 and 6 show a pouch main body having a triangular bottom in which a length of two sides is greater than that of another. In addition, a sealing portion where the pump dispenser 100 is attached can be designed to be inclined at a predetermined angle. That is, the outer appearance of the pouch main body can be varied in accordance with the inclined angle of the sealing portion 206.

In addition, the reinforcing sealing portion 208 can be formed on a side and/or upper and lower portions of the pouch main body 200. the reinforcing sealing portion 208 may be omitted.

FIG. 4 shows a pouch main body having a sealing portion where the pump dispenser is attached is formed in a horizontal direction.

In this case, special reinforcing means is further provided on the pouch main body.

That is, as shown in FIG. 1, the bottom of the main body is provided at its bottom periphery portion with a concave or convex portion 402. The concave or convex portion 402 is formed of a rigid material to provide a more stable structure to the pouch main body 200.

That is, this structure prevents the pouch main body is deformed toward a side or the content from flowing into one place.

As another example of the reinforcing means, a both-sided tape 404 is disclosed in FIG. 2. by attaching the tape on the pouch main body, the self-standing force can be further improved. In addition, an absorption member 204 mounted on a bottom frame of the main body can be also used as the reinforcing means.

As another example, as shown in FIG. 3, a sub-support 408 for supporting a lower portion of the main body can be provided.

FIGS. 7 to 9 shows a variety of examples of the self-standing spouting means 300.

The self-standing spouting means 300 depicted in FIG. 7 comprises a spouting support coupled on the outlet of the lower housing of the pump dispenser 100 and a support 308 extending from the pump dispenser 100 to the bottom 204 of the pouch main body 200. The support 308 is formed in a minimum width and length to save the manufacturing costs and prevent it from reducing the volume of the container. The lower end of the support 308 is bent to provide an enlarged bottom surface contacting the bottom of the pouch body.

The self-standing spouting means 300 depicted in FIG. 8 comprises a spouting tube 306 coupled on an outlet of the lower housing of the pump dispenser 100 and a support 308 extending from the bottom of the outlet 202 of the pouch main body 200 to the bottom 204.

The self-standing spouting means 300 depicted in FIG. 9 is separated from the pump dispenser 100 and a sub-support 310 having an upper end of the means 300 connected to the outer side of the outlet 202 of the pouch main body 200 and extended to an outer bottom 204 of the pouch main body 200.

The sub-support 310 is, as shown in FIG. 10, is formed of plural elastic member formed on an inner surface of the coupling hole 316 so

that it can be securely and easily coupled on the outlet 202 of the pouch main body. At this point, the sub-support 310 is first fitted through the top of the outlet 202 of the pouch main body and screwed coupled on the outlet 202.

In addition, an opening 314 may be formed on the coupled hole 316 so that the sub-support 310 can be more easily coupled.

INDUSTRIAL APPLICABILITY As described above, the dispenser type liquid pouch container is designed to provide a stable self-standing structure and prevent the deformation and folding of the pouch by providing a self-rigidity structure to the pouch main body and disposing self-standing spouting means between the pump dispenser and the pouch main body.
