JP2000109103A - Air-pressure extrusion type soft tube container - Google Patents

Abstract

PROBLEM TO BE SOLVED: To always realize the use of the subject container in beautiful shape by providing an air chamber to be communicated with the outside by a valve structure part to suck air from the valve structure part to allow the shape to be returned to the original one by the restoring force of a container when a container is pressed and a hand is detached even if the container is dent. SOLUTION: The inside of a soft tube container is of a double structure which is divided into a content chamber 5 and an air chamber 6, the content chamber 5 and the air chamber 6 are communicated with the outside at a mouth part 3 of the container and at a valve structure part 4, respectively, and the valve structure part is of a structure in which no air in the air chamber 6 is leaked outside when the pressure is applied to the container. The content chamber 5 is separate from the air chamber 6, and the outer fitting of the container is split into two so that the content chamber is detached/attached to/from the container.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of extruding a flexible tube container by applying air pressure to a body portion of the container, the pressure being transmitted to the air inside the container, and extruding the contents by the pressure of the air. The present invention relates to a flexible tube container of the formula.

[0002]

2. Description of the Related Art In a conventional flexible tube container, a force for pushing the container with a finger is directly transmitted to the contents, and the contents 2 are taken out from a mouth portion 3. In addition, it was a single use disposable method.

[0003]

Conventionally, there have been the following drawbacks. (B) Press the soft tube container with your finger and take out the contents.
The shape of the container gradually changed and did not return to the original shape. (B) When the content was low, the container was dent and it was difficult to discharge the content. (C) The container was greatly deformed each time it was used, and the appearance was not beautiful. (D) When the content becomes small, air may enter through the mouth and return to the original shape, but the content must be squeezed out. (E) It was not possible to replace only the contents with the disposable method. An object of the present invention is to eliminate the above disadvantages.

[0004]

In order to achieve the above object, the flexible tube container of the present invention has a double structure in which the interior of the container is divided into a content chamber 5 and an air chamber 6, and the content chamber is a container. The air chamber has a valve structure portion 4 which shuts out air from leaking out of the air chamber when a pressure is applied to the container by pressing the body portion 8 of the container. It is a structure that leads to the outside at the structural part.

In addition, the content chamber 12 and the air chamber 13 are separately provided so that the used content can be replaced with new content, and the content chamber 12 and the air chamber 13 are detachably assembled and disassembled.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When the flexible tube container is pressed with a finger, the pressure of the air in the air chamber increases and the contents of the contents chamber are pushed out from the mouth. Air is sucked into the air chamber from the valve structure by the restoring force of the container to the extent that the contents are reduced. The container returns to its original outer shape. Even if the above is regarded as one cycle, the container returns to the original outer shape even if it is repeated many times, and the contents can always be pushed out by pressing the same place.

Further, even if the contents are used up, not all of them are discarded, but only the contents room 12 containing the new contents needs to be replaced.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS When the flexible tube container is pressed with a finger and the contents are slightly released, the container is dented, but when the finger is released, air is sucked into the air chamber by the restoring force of the container. The container returns to its original outer shape. The air that has entered the air chamber does not leak out due to a valve that is configured to shut off the air even when pressure is applied to the container, and the pressure in the air chamber rises to push out the contents. By repeating the above, the volume of the content chamber decreases inside the container, and the volume of the air chamber increases in inverse proportion. Rather than throwing away the entire container even if the contents eventually run out, the structure that can be disassembled replaces only the contents room containing the new contents, and the others can be reused.

[0009]

The present invention has the above-described configuration and has the following effects.

By providing an air chamber communicating with the outside in the valve structure, even if the container is pushed and the container is dented, when the hand is released, air is sucked into the air chamber from the valve structure by the restoring force of the container and returns to its original shape. Because it returns, it can always be used in a beautiful shape, and it can also be used by pressing a part that is easy to hold.

Since the contents can be disassembled even when the contents are gone, only the contents chamber containing the new contents needs to be replaced, and it is not necessary to discard the entire contents.
