JP2000109101A - Liquid pack container having pipe with opening/closing mechanism - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reduce the quantity of the refuse by fitting a pipe provided with a U-shape opening/closing mechanism on an elastic pipe with a closed outlet to a part of a closing part of a sheet-like liquid pack container to facilitate the arrangement, to prevent the bulkiness, and to miniaturize the container after the use. SOLUTION: When an end pant of an outlet 1 is twisted off to erect an outlet 1, a U-shape opening/closing mechanism 2 pressed by the wall thickness due to the difference between the inside diameter and the outside diameter of a pipe is returned to its original cylindrical shape by the elasticity. A space to which a liquid is introduced is ensured, and the liquid inside can be taken out by sucking the liquid from the outlet 1 or by directly pressing the liquid pack container 3 to squeeze the liquid. If no strong force is applied, the pipe is returned to its original U-shape by the elasticity. The U-shape opening/closing mechanism 2 is pressed to close by the wall thickness of the pipe, and no liquid leaks. The method to close the U-shape opening/closing mechanism 2 includes a method to hold the outside diameter of a straight pipe part by a C-shaped arm to press the pipe, and a method to cover a U-shaped part by a cylinder for the U-shaped thickness part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for attaching a tube with an opening / closing mechanism to a liquid pack container to facilitate taking out of a liquid.

[0002]

2. Description of the Related Art Conventional liquid pack containers are used for refilling for reusing expensive liquid containers. Also, conventional liquid containers have become larger and more diversified as liquid beverages and liquid detergents have become more diversified, making it difficult to store them at stores and at places of use. In addition, bulky rigid containers increase the cost of transportation. Thus, improvements are required for both producers and users.

[0003]

Therefore, liquid containers that are diversified and large in size and are increasing in demand are increasingly difficult to organize and consume large amounts of resources, resulting in large amounts of garbage.
The present invention has been invented in order to respond to such strong demands of producers and users.

[0004]

Means for Solving the Problems Now, the structure will be described. (A) A U-shaped opening / closing mechanism 2 is provided in an elastic pipe having an outlet 1 closed. (B) A pipe having a closed outlet 1 and a U-shaped opening / closing mechanism 2 is attached to a closed part of the sheet-like liquid pack container 3. The configuration is as described above.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. If the end of the outlet 1 is threaded and the outlet 1 is raised, the thickness of the pipe is compressed by the difference between the inner and outer diameters of the pipe. The mold opening / closing mechanism 2 returns to the original cylindrical shape by elasticity. At that time, a space for introducing the liquid is secured, and the liquid in the liquid can be taken out by suctioning from the outlet 1 or directly pressing and pushing the liquid pack container 3. Then, if a strong force is not applied, the tube returns to the original U shape due to elasticity. The U-shaped opening / closing mechanism 2 is closed by being pressed by the wall thickness of the tube, and does not leak liquid.

[0006] The method of closing the pipe by the U-shaped opening / closing mechanism 2 is as follows. How to squeeze. (B) A method of covering a U-shaped portion of a pipe with a cylinder having an inner dimension only for the thickness of the U-shaped pipe. and so on.

[0007]

As described above, the simple tube provided with the U-shaped opening / closing mechanism 2 is attached to the liquid pack container 3, so that it can be used as an independent container instead of a refill container. And when you display and use the products, you can hang them, and they are easy to organize without taking up space. Slim containers also reduce the cost of transportation. In addition, it does not become bulky when used in a portable manner, and after use, it becomes more compact and the amount of dust can be reduced.
