<p><P>PROBLEM TO BE SOLVED: To provide a cushioning body which is recyclable by injecting or ejecting gas as necessary at low cost. <P>SOLUTION: A bag-shaped cushioning body 1 is formed by affixing edge portions of sheet bodies. Fluid spouts 9 are formed in corner parts of the cushioning body 1. The fluid spouts 9 are formed at diagonal positions of a pair of inner affixed parts, and the cushioning body is used in a swollen state by introducing gas through the fluid spouts 9. In this state, when the external pressure is applied to the cushioning body 1, the effect is generated in which the pair of inner affixed parts are pushed up to the sheet body contact area side, i.e., the atmosphere side. The opposing sheet bodies on the peripheral edges of the fluid spouts 9 are folded in the V-shape by the pushing-up stresses, and the sheet bodies leading to the sheet body contact area side from the fluid spouts 9 can be effectively and tightly attached to each other. Leakage of gas from a fluid storage chamber 3 can be effectively suppressed by the tightly attaching effect of the sheet bodies leading to the sheet body contact area side from the fluid spouts 9. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
