Description

DESCRIPTION

DISPENSER TYPE LIQUID POUCH CONTAINER

TECHNICAL FIELD

The present invention relates to a dispenser type liquid pouch

container and, more particularly, to a container that is designed to

securely maintain its self-standing force even when depressing force is

applied to an associated pump dispenser.

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

when force is applied to a pump dispenser.

To achieve the above objective, a flexible pouch container of the

present invention is designed having a shape of a conical type, a seal

portion of the flexible pouch container being disposed to be crossed to

each other to be stable in the standing position.

Between a pump dispenser and a bottom of the pouch,

self-standing dispensing means is disposed so that the self-standing

force can be maintained even when pumping force is applied to the pump

dispenser. More concretely, the present invention provides a dispenser type

liquid pouch container comprising a flexible pouch main body for
