BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting and sealing body composed of a bag body partitioned into a plurality of small chambers.

[0002]

2. Description of the Related Art A conventional valve body has a flat tubular structure made of a flexible film, and one end of the valve body is attached to the outside of the hermetically sealed body and the other end is opened to the interior of the hermetically sealed body. When the fluid is fed from the external opening after the valve and then the feeding is stopped,
It is known that the internal pressure of the sealed body and the restoring force of the flexible film forming the tubular shape cause the membranes of the inner openings to come into close contact with each other to close the valve, thereby keeping the sealed body airtight. Such a valve body has been regarded as useful because it can be easily attached to the closed body and the tightness is ensured.

[0003]

However, such a valve body has a drawback that the airtightness of the sealed body is impaired by repeatedly feeding the fluid into the sealed body and extracting the fluid from the sealed body. Had. That is, the fluid is sent to the sealed body directly from the outer opening of the valve body or by a transport pipe inserted therethrough, and the fluid is withdrawn from the sealed body from the outer opening of the valve body through the inner opening. Since the withdrawal pipe inserted into the body is used for withdrawal, repeating this operation causes the fluid itself or its pressure and / or the shape of the pipe to distort the flexible membrane forming the valve body, resulting in close contact between the membranes. And the airtightness of the sealed body was impaired.

In Japanese Utility Model Laid-Open No. 61-20969, in order to solve this drawback, a thin piece of rigid elasticity is attached along the wall of the valve body near the inner opening side end of the valve body to prevent distortion of the membrane. However, attaching a thin piece of rigid elasticity to the valve body requires time and effort such as providing a pocket in the valve body, so it is difficult to say that this is a simple method.

Further, in order to close the conventional valve body, it is necessary to sufficiently increase the internal pressure of the sealed body, and if this internal pressure is insufficient, the hermeticity of the sealed body cannot be maintained. A bag using such a valve body is also known, but it is only applied to a single bag. In such a single bag, if the bag is damaged, almost all of the fluid filled inside is discharged, which may cause serious trouble.

On the other hand, a structure in which a valve body communicating with the outside is separately provided for each small chamber of a bag having a plurality of small chambers is conceivable, but there is a drawback that the manufacturing is complicated and the cost becomes high. It was The present invention solves the above drawbacks and provides a connecting sealing body that is easy to manufacture and inexpensive to manufacture, and that can be used for various purposes without causing serious trouble even if a part of the sealing body is damaged. With the goal.

[0007]

Means for Solving the Problems, Actions and Effects of the Invention In order to solve the above-mentioned problems, in the connecting sealing body of the present invention, flexible films having adhesiveness are superposed on each other, and A plurality of non-adhesive portions are arranged along the direction, and a fluid passage capable of communicating the superposed surface of the flexible membrane and the outside of the superposed surface is provided between the non-adhesive portions adjacent to each other. A valve body portion provided, a bag body arranged so that the valve body portion longitudinally cuts through, and a bag body provided so as to cross a non-adhesive portion of the valve body portion. It is characterized by having a partitioning part for dividing the room . This connecting seal is
The valve body is opened by inserting a pipe from the outside into the non-adhesive portion of the valve body, and the fluid sent from the pipe is filled in each small chamber through the fluid passage of the valve body. The valve is closed by removing the pipe.

[0008] That is, according to the connecting enclosure of the present invention, pie
It is possible to fill each cubicle in the fluid in the filling operation once according flop, filling operation of the fluid becomes easy. In addition, since the valve body has a configuration in which a plurality of valve bodies are provided between a pair of flexible membranes and each valve body is arranged in each small room, compared to a configuration in which a valve body is provided for each small room one by one. Therefore, simple and low-cost manufacturing is possible.

Further, the same effect as the structure in which the valve element is provided for each small room can be obtained. That is, even if one small chamber is damaged and the fluid is removed, the other small chambers are still filled with the fluid, and it is possible to prevent a large trouble from occurring. The connected sealed body filled with fluid is
It mainly has a cushioning function and a heat insulating function, and can be used for various purposes. The cushioning function of the connecting sealing body of the present invention is
It is obtained by the internal pressure of the fluid sent to the plurality of sealed bodies of the connected sealed body and / or the property of the fluid itself. Further, the adiabatic action is due to the fact that the convection of the fluid sent to the connecting hermetically sealed body occurs only in each hermetically sealed body of the hermetically sealed hermetically sealed body, and therefore the amount of heat applied to the hermetically sealed hermetically sealed body from the outside does not easily fluctuate.
