Description of Invention (16), or a composite sheet made of such materials. Examples of the plastic sheet include polyethylene, polypropylene, polyester, polycarbonate, and nylon resin. It can also be formed by using such a soft sheet or a composite sheet as a material, closely bonding two material sheets and heat-sealing the surroundings with a predetermined width, and then performing heat welding, or for example, as an outer layer, Polyethylene or polypropylene and the inner layer is made of nylon resin or polyester. * Of course, the check valve 3 can be configured as shown in FIG. 20. Fig. 21 is a second configuration example showing a case where two flexible sheets are used by folding each other. First, a sheet 7 constituting the inner wall and a sheet 8 (a) constituting the outer wall are prepared. Each of the wide sizes (A) and (B) is the width of the film 8 being larger than that of the film 7. This is for the same reason as the configuration example shown in the previous figure. The method is to fold in half for each, insert each way between the pieces 8 of the half-folded piece 7 in the same direction (b), insert the check valve 3, and weld along the circumference of the piece 8 while welding, from the upper and lower ends. Set the weld line (c) at the desired position. In this case, the weld line 17 A is enlarged to the full width, and 17 B leaves a connecting portion 18 connecting the two air chambers. In this case, as shown in the figure (d), if the welding portion is made into an l-shape, only the connecting portion 18 is formed, and when the air is filled, as shown in FIG. 18 (b), the continuous connection portion 1 at the bottom is formed. The 6 series maintains the shape of the plane, but as shown in Fig. 21 (e), when "dissolving according to the open state", as shown in Fig. 18 (c), another air chamber can be provided at the bottom.

Description of the Invention (17) First, prepare the tube-like flexibility as (a) Chip, and set 4 weld lines at the desired position. Then insert the check valve 3 in the end of 1 and weld the two ends 10. In this case, the weld line 17 is formed by connecting portions 18 which contact all the air chambers. However, for 1 7 B, as shown in the figure (d), if the welded portion is made into a Λ shape, p forms the connecting portion 18, and when the air is filled, as shown in FIG. 18 (b), the bottom connection The design section 16 maintains a flat shape, but as shown in FIG. 21 (e), when it is welded in an open state, as shown in FIG. 18 (c), another air chamber can be provided at the bottom. In the case of this example, it is because 17 A is also provided with a connecting portion. In FIG. 18 (c), the upper connecting portion 16 will also generate a small air chamber 0 (f) as a longitudinal sectional view. It is in a state of squeezing a cylindrical body. Although this example is the simplest structure, the air in the air chamber is not sufficiently communicated with the inner part of the curved part because the inner side is closely attached to the outer side. Even if it is filled with air, it is highly likely that only the air in the check valve 3 The chamber expands. Fig. 23 is a fourth configuration example, and shows a case where it is composed of only one sheet. One flexible sheet is prepared by successively arranging the part 7 constituting the inner wall and the part 8 constituting the outer wall shown in FIG. Next, as shown in (b), clamp the check valve 3 and fold it in half, and weld it along the end to form a weld line 17 B. This is then folded in half as shown in (c) and (d) and the ends 1_2 are welded. (Please read the precautions on the back before filling out the packing ^ | ^ 丨: write order: -line.

Description of the invention (18) If the weld line 17 A is formed in an open shape (: 2 shape), only the connecting portion 18 is formed, and when the air is filled, as shown in FIG. 18 (b), the bottom connection The part 16 maintains a flat shape, but as shown in Fig. 23 (c), when it is welded in an open state, another air chamber can be provided at the bottom as shown in Fig. 18 (c). (D) is a normal front view showing a state where the cylindrical body is flattened. Figs. 24 and 4 show a meandering prevention member of the air chamber communicating portion 18. Figs. 4, 5, 22 and 23 In the method shown in the figure, as shown in FIG. 24 (d), the sheet 7 constituting the inner wall and the sheet 8 constituting the outer wall are closely adhered at the zigzag portion, and the communication between the air chambers 4 and 5 cannot be ensured, so that the check valve 3 The inflowing air cannot be expanded through the communication portion 18 and only in the air chamber 4 on the side with the check valve 3, because the two air chambers cannot be balanced under good balance. Due to the expansion, there are disadvantages such as that the position of the object to be stored cannot be fixed.... As a result, by inserting an adhesion preventing member made of an elastomer into the communication portion 18, as shown in FIG. 24 (e), As shown in the figure, it is possible to ensure the communication portion and to expand the air chamber uniformly. Here, the adhesion prevention member is shown in the figure as a shape in which longitudinal ribs are formed on a planar member, provided that it has a moderate degree of flexibility and The elasticity can ensure the shape of the channel, but it does not need to be the shape as shown in the figure, but can be a cylindrical body.
