  An arbitrary number of through-holes 14 and 7 are provided in the front and rear surface portion 12 of the inner bag body 10 and the front and rear surface portion 3 of the outer bag body 1 at substantially the same positions during assembly. In addition, a reinforcing frame member 15 made of a synthetic resin film or the like that is in close contact with the periphery of the through holes 14 and 7 to obtain high airtightness is integrally provided, and the through holes 14 and 7 are provided with a strong thickness, At the same time, a packing effect is provided when tightening.

  Further, the fastener 5 of the flexible outer bag body 1 is opened, the flexible inner bag body 10 is accommodated therein, and the inside and outside are connected by the pipe-shaped connecting member 20 that fits the through holes 14 and 7 together. The bag bodies 10 and 1 are provided so that they can be assembled, and a high-pressure gas from a pressure source is supplied by the connecting member 20, and the inner bag body 1 and the outer bag body 10 are fitted into the through holes 14 and 7.

The fastener 5 of the outer bag body 1 needs pressure resistance to maintain the expansion force of the inner bag body 1, and the fastener 13 of the inner bag body 10 maintains air in a predetermined pressure higher than the surrounding area. A certain air permeability is required. This predetermined air permeability is referred to as micro-air permeability in the present invention.
Further, the fastener 5 of the outer bag body 1 has the air 8 between the inner bag body 10 and the outer bag body 1 because of the air permeability of the outer bag body 1 as compared with the conventional case where the bag body is not air-permeable. Since the air permeability for discharging the air is not an indispensable condition, it is possible to employ a fastener having a free configuration with respect to the air permeability.

In the case of the embodiment of the present invention, as the fastener 13 of the inner bag body 10, there is provided a micro-breathable fastener 13 having a micro-breathability with less pressure resistance and breathability than the outer bag body.

And since the micro breathability fastener 13 of the inner side bag body 10 has the structure which has substantially uniform micro air permeability over the whole fastener, while being able to ease the pressure resistance of the whole fastener by micro air permeability, it is equal Exhaust sound can be weakened by the fine air permeability, and unpleasant feeling due to concentrated exhaust sound from both ends and gaps of the fastener can be alleviated.
In this case, the high-pressure gas is supplied from the pressurizing source of the pressurizing mechanism while supplementing the air permeability of the micro-breathable fastener 13 so that the internal air is ventilated by the micro-breathable fastener 13 while maintaining the high-pressure gas state. be able to.
In addition, the present invention is configured so that the fastener 5 of the outer bag body 1 and the fastener 13 of the inner bag body 10 are not in direct contact with each other, so that the opening and closing of the fasteners is not hindered. Reference numerals 9 and 16 denote slider handles for the fasteners 5 and 13, respectively.

  In this case, the arrangement positions of the fasteners 5 of the outer bag body 1 and the fasteners 13 of the inner bag body 10 can be removed at positions where they do not overlap each other. As described, the diaphragm body 17 is provided between the outer bag body 1 and the fasteners 5 and 13 of the inner bag body 10 along the longitudinal direction. The diaphragm body 17 is doubled from both sides of the fastener 5 in the longitudinal direction along the lower side of the fastener 5 of the outer bag body 1, and is provided so as to face the opposite fasteners 5 and 13.

In the case of this embodiment, the diaphragm body 17 is made of a non-breathable film body, and the fastener 13 of the inner bag body 10 is in close contact with the outer bag body 1 through the non-breathable film body. It is configured to enhance.
The diaphragm body 17 can also be provided on the inner bag body 10 on the upper side of the fastener 13. In this case, the slider handle 16 of the fastener 13 is covered with the diaphragm body 17, making it difficult to operate from the outside. However, in the case where the fasteners 5 and 16 are disposed at positions where they do not overlap each other, the fastener 13 is in close contact with the outer bag body 1 via the diaphragm body 17, so that the airtightness of the fastener 13 is improved. be able to.
