Alternatively, a double-sided tape with a detachable structure or cloth fastener is used on the surface of the cushioning material 4a, and the gas storage bag 2a
The buffer material 4a is fixed.
A nozzle 3 such as an inlet / outlet is provided at the bottom of the gas storage bag 2a as gas suction / discharge means, and is connected to an existing pipe to suck and discharge gas into the gas storage bag 2a.
Then, the suction and discharge of the gas to the gas storage bag 2a and the adjustment of the gas pressure are performed by supplying or exhausting air between the container box 1 and the gas storage bag 2a from the outside using the blower 9. Adjust to adjust. When the gas is sucked into the gas storage bag 2a, the air is not supplied or exhausted, or the gas is stored by holding the air at a pressure lower than the gas suction pressure. Moreover, when supplying stored gas, the same pressure as predetermined operation gas pressure is set to air pressure, and the gas storage back | bag 2a is pressed with the air pressure shown by the arrow of FIG. The gas storage bag 2a contracts as shown by the broken line in FIG. 1, and the gas in the gas storage bag 2a is discharged.
Alternatively, although not shown, when the container box is not airtight and the blower and air are not used, an annular weight is loaded on the upper surface of the gas storage bag and the pressure of the gas is measured using a wire and a weight. Make adjustments and supply / discharge.

As described above, the gas storage bag 2a is formed in a horizontal cylindrical shape, and the lower portion of the bottom surface is supported by the buffer material 4a. Therefore, no local stress is generated in the film body in order to support the load on average, and the nozzle 3
No local stress is applied to the mounting part.

FIG. 2 shows a gas storage bag 2b formed in an outer shell of a rectangular parallelepiped container box 1 in a laterally flat bottomed dome roof that can be inflated and contracted, or in a sealed open bag shape or bottom open type bag body.
Is shown, and the bottom periphery is hermetically fixed to the bottom wall.
This structure is opened so that the periphery of the bag body does not come into contact with the inner wall surface of the outer shell, so that the upper dome can be expanded and contracted away from the ceiling and the side wall. By filling 4b, the movement in the horizontal direction is restricted so that the side wall is not touched and damaged, and the interval is not increased and no dead space is formed.
A nozzle 3 such as an inlet / outlet as a gas suction / discharge means is provided in the bag body through the bottom wall of the container box 1 in the case of a sealed bag body of a seashell shape, and in the case of a bottom opening type bag body. It is provided directly on the bottom wall of the box 1.
Gas suction / discharge and pressure adjustment into the gas storage bag 2b are performed by using the blower 9 to send or exhaust air between the container box 1 and the gas storage bag 2b from outside. Adjust and do. When the gas is sucked into the gas storage bag 2b, the air is not supplied or exhausted, or the gas is stored by holding the air at a pressure lower than the gas suction pressure. Moreover, when supplying stored gas, the same pressure as predetermined operation gas pressure is set to air pressure, and the gas storage back | bag 2b is pressed with the air pressure shown by the arrow of FIG. The gas storage bag 2b contracts as shown by the broken line in FIG. 2, and the gas in the gas storage bag 2b is discharged.
Alternatively, although not shown, when a blower and air are not used in a container box that does not have airtightness, an annular weight is loaded on the upper surface of the gas storage bag, and the pressure of the gas is adjusted using a wire and a weight. Inhalation and discharge should be performed.

In this way, the gas storage bag 2b is formed in a horizontal flat bottom dome roof and is supported by pressing the periphery of the lower side of the side wall surface with the buffer material 4b. Therefore, the film body does not rub against the surface and does not have to worry about damage or breakage.
Although the fixing part of the bottom edge of the gas storage bag 2b and the bottom wall is held by a fixing tool (not shown) and the buffer material 4b is in contact with the lower part of the side wall surface, the fixing part is in the horizontal direction. Since peeling stress and local stress are not generated, damage deterioration of the film body can be prevented.
Moreover, since the upper part of the gas storage bag 2b is open and separated from the ceiling and the side wall of the container box 1, the operability of expansion and contraction is good.
Further, since no dead space is generated around the lower side of the gas storage bag 2b, the gas storage efficiency is good, and the nozzle 3 can be easily attached to the bottom of the container box 1.

FIG. 3 shows the cushioning material 4a in FIG. 1 made of a heat insulating material 5a, and further provided with a heat insulating material 5b extending from the ceiling wall surface to the side wall surface in the container box 1.
The heat insulating material 5a supporting the load uses, for example, hard polyurethane, rock wool,

Further, the lower portions on both sides of the bellows-like gas storage bag 2 are provided with engaging members 16b and supported so that the guide wire 17 can be slid.

As shown in FIGS. 5 to 7, the gas storage bag 2 is formed in a bellows shape with the air chamber 7 and the gas chamber 8 of the horizontal cylinder facing each other through the partition wall 13, and the gas storage bag 2 is suspended. Since it is supported and stretched and contracted by air, the bellows-shaped membrane body can be expanded and contracted, and the gas pressure can be adjusted and suction and discharge can be performed with good operability.

The flexible membrane material forming the gas storage bag 2 is, for example, a sheet body made of a synthetic resin material such as polyolefin resin, ethylene vinyl acetate resin, polyvinyl chloride resin, or fiber such as polyester fiber or glass fiber. In addition, a sheet body having air tightness and liquid tightness such as a cloth film material coated with a synthetic resin such as the above-described polyvinyl chloride resin is used.
Since this gas storage bag 2 is housed in the container box 1, it is not exposed to sunlight or outside air, so there is no deterioration due to ultraviolet rays, etc., and the film body is prevented from collapsing due to strong winds or being damaged by flying objects. It is possible to ensure safety and durability.

The box 1 having a rectangular parallelepiped shape has a simple structure as an outer shell structure that protects the film body, and has a length of, for example, about 20 to 40 feet (6 to 12 meters) and a volume of 20 to 40.
