[Prior Art] ^ As shown in Fig. 11 to Fig. 13, a hollow structural member which is used as a heat insulating or cushioning member and which has an air layer is used. In the hollow structural member 60 shown in Fig. 11, the bonding line portion 64 is formed by leaving a space on the planar base sheet member 61, and the air chamber forming sheet 62 is welded to the base sheet and the other. A plurality of air cells 63 are placed between the sheets to form a plurality of air cells 63. The hollow structural member 60 is formed as a structure in which the bubble-buffering sheet having heat insulation and cushioning properties is formed into a structure. The T-melt is connected to each other, and the air-insulating member 80 is placed in the hollow structure member. The hollow structural member 80 shown in Fig. 13 is sandwiched between the two sheets 81 and 82, and a plurality of sponge spacers 83 are interposed therebetween. The air chambers 8 are formed by maintaining a certain distance between the two sheets 8 1 and 8 2 . Further, in the above-described three examples, the peripheral members of the hollow structural member are welded to each other or connected to each other, and the hollow structural member is formed as a whole to form a plate-shaped member having a specific thickness. 200811390 (2) [ [Patent Document 1] Japanese Patent Laid-Open Publication No. 2005-1996 3 [Abstract] [Problems to be Solved by the Invention] However, in the first and second hollow structural members 60 and 70 described above, an air layer is formed. The two sheets are joined at the place where they are welded, and the air layer disappears. Therefore, in the place where the air layer disappears, the heat efficiency is remarkably lowered, and depending on the temperature condition, condensation or icing occurs in this portion, and the thermal efficiency is further deteriorated. Further, in the third hollow structural member 80 described above, although the thickness of the air layer is constant, there is a problem that the air in the air chamber cannot be removed and the folding thereof is reduced. The present invention has been made to solve the above problems, and an object of the invention is to provide a hollow structural member which has an air layer having a substantially uniform thickness and which can improve cushioning performance.

In the hollow structural member of the present invention, the two sheet members described above can be obtained by joining the end edges of the hollow body. In addition, it is possible to obtain a gas supply port for injecting and discharging a gas. Further, the joint portion between the sheet member and the air permeable sheet member is provided with a reinforcing sheet which has a bonding force between the sheet member and the permeable sheet member. In the heat insulating member of the present invention, the hollow structural member is provided as a heat insulating portion. Further, the cushioning member of the present invention includes the above-described hollow structural member as a cushioning portion. [Effects of the Invention] The hollow structural member of the present invention is obtained by interposing a ventilating air permeable sheet member between the two sheet members that are opposed to each other on the opposite surface of the two sheet members. In the state in which the gas is sealed between the members, the gas is formed in the gas-tight sheet as a whole, and a gas layer such as an air layer is formed between the two sheet members. The adhesion preventing member or the splicing preventing member or the sealing member material is interposed between the sponge ball, the PE cotton, the quilt cotton, the non-woven cotton, etc., so that the thickness of the gas layer is the sheet member and the ventilation. The joint size of the sheet member is set to be almost constant, and there is no local thinning, and it can be made into a nearly uniform thickness. Further, in the hollow structural member of the present invention, since the two sheet members are joined at the edge portion of the hollow body, the airtight structure as a whole can be maintained. In addition, the hollow structural member of the present invention can be stably formed after forming a gas supply port capable of injecting and discharging the gas into the gas inlet -6 - (4) 200811390. In the state in which the internal gas is discharged, the hollow structural member has a sheet shape, so that it can be folded and accommodated in a thin and small manner. Further, the hollow structural member according to the present invention is provided with a reinforcing sheet that reinforces the bonding force between the sheet member and the air permeable sheet member at the joint portion between the sheet member and the air permeable sheet member, and therefore, the sheet member and the permeable thin φ sheet member The joint strength is improved. Further, the heat insulating member of the present invention includes the above-described hollow structural member as the heat insulating portion, and can have an air layer having a substantially constant thickness, and has an excellent heat insulating effect. Further, the cushion member of the present invention has the above-described hollow structural member as the buffer portion, and therefore has an excellent cushioning effect. [Embodiment] ® Hereinafter, a hollow structural member, a heat insulating member, and a cushioning member according to the present invention will be described based on the following examples. [Embodiment 1] Fig. 1 is a view showing a first embodiment of a hollow structural member according to the present invention, (a) a sectional view of the drawing, (b) a plan view of the drawing, and a hollow structure shown in Fig. 1 of the second drawing. An oblique view of the section of the component. In this example, the hollow structural member 1 is composed of two rectangular airtight sheet members n and 1-2, and a rectangular ventilation disposed between the sheet members 1 and 2 (5) 200811390 The sheet member 13 is formed. The sheet members U and 1 2 are formed of a thermoplastic resin such as chlorinated ethylene, and as shown in Fig. 1(b), the bonding wire portions 17 around them are thermally welded and joined to form a gas cell 18 Being kept airtight. Further, a spherical body 25 formed of an elastic material such as a sponge for preventing adhesion of two sheet members is incorporated in the gas chamber 18. This spherical body 25 is a member for preventing the sheet member u from being in close contact with each other as will be described later. Further, the sheet member 1 1 is provided with a gas supply port 14 which is capable of injecting and discharging air which forms the gas chambers 18 in the sheet members 1 1 and 1 2 . Further, as the sheet members 11 and 12, as long as they are airtight as a whole, a polyethylene sheet, a polyester sheet, a heat insulating sheet, a rubber sheet, a brush cloth, a resin coated cloth or the like may be used. Further, the joining around the sheet members 1 1 and 1 2 is not limited to heat welding, and it is sufficient if it is joined by other means to maintain airtightness. Further, the air permeable sheet of the air permeable sheet member 13 is a mesh bottom sheet of a polyester resin, and allows gas to pass easily. As the breathable ® sheet member 13 , a mesh underlayer sheet made of synthetic resin, a nonwoven fabric, a through-hole fabric underlayer sheet, a lattice-like or punched sheet, a synthetic or natural fiber cloth, or the like can be used. Further, one or a plurality of rectangular airtight sheets may be used as a permeable sheet. In this example, as shown in Fig. 1 and Fig. 2, the air permeable sheet member 13 is placed on the opposite surface of the sheet member 1 1 and the 1-2 sheet member which are disposed opposite to each other, and is bonded to the line portion 1 5, 1 6 interactions are joined by heat fusion. Further, in this example, as shown in Fig. 3, when the bonding wires 15 and 16 are thermally welded through the reinforcing sheets 19, the bonding strength can be enhanced -8 - 200811390 (6) degrees. . This reinforcing sheet 19 can be omitted as needed. According to the present example, in a state where the gas is sealed between the sheet members, the gas is passed through the airtight sheet as a whole between the sheet members of the two sheets. A gas layer such as a layer of air is formed while the air is formed. Since the thickness of the layer is set to be almost constant by the joint size of the sheet member and the air permeable sheet member, it is possible to form a hollow structural member having a substantially uniform thickness without being locally thinned, and it is possible to have a large heat insulation. Force and buffering force. Further, in addition to φ, the gas supply port is formed in a state in which the gas in the hollow structural member is filled, and the gas layer having a certain thickness can be stably formed, and the hollow structural member is in a state in which the internal gas is discharged. It is in the form of a sheet and can be folded and stored thin and small. Further, since the hollow structural member 10 thus formed is excellent in heat insulating force and cushioning force, it can be used as a sheet-like heat insulating material, a cold-preserving material, and a cushioning material. Next, the effect of such a Φ when the hollow structural member is used as a heat insulating material will be described. Fig. 4 is a graph showing a first simulation result using the hollow structural member of the embodiment, Fig. 5 is a graph showing a second simulation result using the hollow structural member of the embodiment, and Fig. 6 is a view showing the use of the implementation. A curve of the third simulation result of the hollow structural member of the example. In this simulation, as a conventional example, the configuration shown in Fig. 2 is used as the following size. Sheet thickness t: 0.4mm Sheet material; Vinyl chloride, polyester resin Air layer thickness D: 50mm -9 - 200811390 (7) No air portion width W: 2mm No air portion distance p: 80mm In addition, as this application In the embodiment of the present invention, the configuration shown in Fig. 1 is set to the following size. Sheet thickness: 0.4mm · Sheet material: Vinyl chloride, polyester resin Air layer thickness: 50mm φ Further, common matters, air: large volume, no temperature change, heat preservation (cooling) liquid: water insulation (cooling) Area: 1πι2 (平方平方) (The length of the air-free part of the previous insulation material: 84〇111111 (1000-2x80) Insulation (cooling) Liquid depth: a little depth, the internal temperature is calculated as the liquid side inner wall temperature of the insulation (cooling). The first simulation shown in Fig. 4 is a case where the hollow structural members are sandwiched between warm water of 40 ° C and air of 20 ° C. This is equivalent to storing hot water in the bath, and is insulated with a heat insulating cover. The second simulation shown in Fig. 5 is based on the case where 90° (:: hot water and 0° (: empty 'gas) sandwich each hollow structural member. This is equivalent to the heat to be consumed. The case where water is kept in cold air. The third simulation shown in Fig. 6 is based on the case where 5 pieces of cold water and 3 〇 of its air sandwich the hollow structural members. This is equivalent to cold water for cooling. In the case of outside air. 10- 200811390 (8) Any one Compared with the conventional example, the simulation has an effect of 30% or more on the thermal conductivity (Kcal/m2 · h°C), and it is known that the examples of the present application are excellent in heat preservation and cold retention. The hollow structural member shown in Fig. 1 is used as a heat insulating member as an example of a bath cover, (a) is a sectional view, and (b) is a plan view. In this example, as the bath cover 20, three covers are provided. The members 21, 22, and 23 are arranged to be used. In this example, the cover members 21, 22, and 23 are arranged on the hot water # of the bath 40 so that the hot water surface is not in contact with the air, as in the first simulation described above ( In the case of Fig. 4, it is possible to maintain warm water for a long period of time than the conventional hollow structural member. Fig. 8 is a view showing an example in which the hollow structural member shown in Fig. 1 is used as a container for a beverage water bottle. In this example, the container 50 is formed into a three-dimensional sheet member 41, 42 and a ventilating sheet member 43 to form a three-dimensional hollow structural member having a bag-like air chamber 44, and is configured to accommodate beverage water inside. 50 bottles of PET bottles. In addition, the symbol 45 ^ in the figure indicates The sealing body which is placed in the mouth of the container 50 and which can be opened and closed in a sealed state. According to this example, when the warm bottle is placed in a warm bottle, the second simulation (Fig. 5) Compared with the conventional hollow structural members, it has a high heat retention capacity. In addition, when the cold beverage water is placed in the PET bottle, it has excellent cold retention power as in the third simulation (Fig. 6). Here, when the structure of the present invention is used in the various forms described above, the amount of injected air is small, and the injected air leaks for some reason, and the internal pressure P of the gas chamber 18 is subjected to surface pressure due to load. P is reduced, and it is possible to produce 11 200811390 (9) The state in which the outer airtight sheet is in close contact with the inner airtight sheet. In such a state, the heat cross flow rate is lowered, and the heat dissipation is increased, and the heat retention property is lowered. Therefore, in the present invention, as described above, a plurality of spheres 25 are interposed in the space in the gas chamber 18 so that the inner and outer sheet members do not cause adhesion, and the gas layer such as the air layer is maintained as a layer. Shape to maintain insulation. Of course, the spheres 25 can be formed from other well-known elastic materials. Further, in the illustrated embodiment, the container is described as having a heat insulating capacity and a cold-keeping property, but it may also function as a buffer container for protecting the stored contents from the impact. Thus, when used as a buffer container, it is possible to select various shapes by fitting various articles inside. [Embodiment 2] Fig. 9 is a cross-sectional view corresponding to Fig. 1(a) of a second embodiment of a hollow structural member according to the present invention, and Fig. 10 is a view corresponding to Fig. 9 The hollow structural member is a cross-sectional view corresponding to the example of Fig. 8 used as a container for a beverage water bottle. In the present embodiment, in order to prevent the adhesion of the two sheet members, the adhesion preventing member material 51 formed of PE cotton, cotton quilt, non-woven cotton or the like is present in the air chamber 18, and only this point and the first The embodiments are different. Of course, the member for blocking the blocking member member 5 1 can also be formed by other well-known materials having similar properties. Further, in the above embodiments, the hollow structural member has a layer of air, but the air layer may be formed of two or more layers. -12- 200811390 (10) Further, the hollow structural member of the present invention can be used as a bath cover, an automobile glass freezing prevention sheet, an automobile body cover, a cold-proof cloth, a frost-proof sheet, a heat insulating sheet, a heat preservation bag, and a bottle cooler bag. , pot insulation bag, rice ^ barrel insulation bag, insulation tube, life jacket, room exposed sheet, tent, heat-resistant sheet, freeze prevention sheet, greenhouse, floating bag, boat, cold food transport bag for fresh food, art craft storage bag, food utensils Storage bags, clothing storage bags, electronic and electrical machine transport bags, precision machine transport bags, hat storage bags, φ shoe storage bags, egg storage bags, camera cases, etc. Further, in each of the above examples, the hollow structural member can be in a state of exhausting air, and has an advantage that it does not occupy a space in storage. Further, the hollow structural member has no fine unevenness other than the air supply port, and is not intentionally attached to the dirt, and can be easily wiped and cleaned. Further, when it is necessary to discard the long-term change or large damage of the hollow structural member, it is possible to reduce the volume of the waste by not using a heat insulating member made of glass fiber or synthetic resin.
