むものである。[Prior Art] A conventionally used gas filling valve integrally formed in a hollow body such as a floating ring is a closing valve for sealing the filled gas and a reverse valve for preventing leakage of the filled gas. Since it has a double structure with a stop valve, it is thick and the closing valve projects from the surface of the hollow body. This gas filling valve is embedded in the hollow body except when filling the gas, is drawn out from the hollow body when filling the gas, and is a space created by deforming the check valve by pushing the gas filling hole from the outside. Then, the gas is applied with pressure to fill the gas, then the gas is sealed, and the gas is pushed again into the hollow body.

っている。The leak prevention valve 8 is configured by stacking the close contact valve member 4 and the sealing valve member 6 with the intermediate member 5 interposed therebetween, has a larger area than the gas filling hole 3, and The heat sealing portion 7 is attached to the inner wall of the base material 2 a forming the hollow body 2 around the filling hole 3. The close contact valve member 4 constituting the leak prevention valve 8 is a rectangular thin film in which the gas filling hole 3 and the hole 4a concentric with the gas filling hole 3 are formed.
A sealing valve member 6 that seals the gas filling hole 3 is attached via an intermediate member 5 formed of a rectangular thin film that forms a ventilation path 5a that communicates from the gas filling hole 3 into the hollow body 2. Both the close contact valve member 4 and the sealing valve member 6 are made of a flexible film made of a soft synthetic resin such as polyester, nylon, ethylene vinyl alcohol or the like having low gas permeability like the base material 2a forming the hollow body 2. In this case, polyethylene is laminated on the inner side, and they are adhered to each other by the heat seal portion 7. Further, since the intermediate member 5 forms the ventilation passage 5a communicating with the hollow body 2 through the gas filling holes 3 and 4a, the intermediate member 5 has a higher temperature than the base member 2a, the close contact valve member 4, and the sealing valve member 6. It is a thin film made of a polyester resin or the like that melts at 1, and is not heat-sealed when the leak prevention valve 8 is attached to the hollow body 2. Furthermore, each end of the three sides of the leak prevention valve 8 except one side where the intermediate member 5 is installed is also adhered to the inner wall of the hollow body 2 by the heat seal portion 7. One end of the leakage prevention valve 8 on which the intermediate member 5 is installed is not attached to the hollow body 2 and is open, and the intermediate member 5 and the open end allow the ventilation passage from the gas filling hole 3 into the hollow body 2. Is formed, and the hollow body 2 can be filled with gas.

中空体2内からの気体の漏洩を防ぐことができる。The gas filled in the hollow body 2 is generally a gas having a specific gravity smaller than that of air such as helium, and the tip of a gas introduction pipe introduced from a gas cylinder or the like to the gas filling valve 1 formed in the skin of the hollow body 2. The nozzle made of neoprene or the like attached to the is closely contacted and filled. The gas to be filled is filled in the hollow body 2 through the air passage 5a formed between the close contact valve member 4 and the sealing valve member 6 by the intermediate material 5. When the inside of the hollow body 2 is filled with gas in this way, pressure is applied from the inside of the hollow body 2 by the gas, and the space between the contact valve member 4 and the sealing valve member 6 is pressed without any gap, Since the ventilation path 5a formed by the material 5 is blocked,
It is possible to prevent gas from leaking from inside the hollow body 2.

止され、充填された気体の漏洩を防ぐことができる。[Operation] The gas filling valve of the present invention comprises a synthetic resin sealing valve member made of a flexible thin piece that closes the gas filling hole on the inner surface of the base material. Is formed by arranging a thin film intermediate material having a high melting point so that one end of the intermediate material communicates with the gas filling hole, and by attaching a heat seal so as to form a ventilation path communicating with the inside of the hollow body through the intermediate material. As a result, the gas filled inside passes through the gas filling hole, the base material or the close contact valve member, and the ventilation path created by the intermediate material installed between the sealing valve member and into the hollow body. Is filled. When the gas is filled in the hollow body, an internal pressure is generated, so that the space between the base material or the close contact valve member and the sealing valve member is pressed from the inside to be in close contact with each other, and the air passage is closed. Is sealed, and leakage of the filled gas can be prevented.

Prepare a laminated film with a total film thickness of 25 to 28 μm, form gas filling holes with a diameter of 5 mm in this laminated film, and use a polyethylene film with a film thickness of 12 μm to form a film with a thickness of 40 mm.
A rectangular close contact valve member having a size of 80 mm and a sealing valve member were manufactured. An intermediate material made of a polyester film having a film thickness of 12 μm is sandwiched between the close contact valve member and the sealing valve member, and these are laminated to each other as a leak preventive valve, and a heat sealer is used to apply a heat seal to the polyethylene film side of the laminated film. Then, the gas filling valve of the present invention was formed.
Next, the laminated film and the laminated film having the gas filling valve were heat-sealed with a circular heat sealer so that the polyethylene film side was inside, and a hollow body was made into a bag.

A synthetic resin sealing valve member made of a thin film intermediate material having a melting point higher than those of the members is arranged between the base material and the sealing valve member so that one end thereof communicates with the gas filling hole. However, since the heat seal is adhered so as to form a ventilation path communicating with the inside of the hollow body through the intermediate material, the gas can be filled into the hollow body at a high speed, and the leakage of the filled gas is small. Therefore, the hollow body can be used for a long time.
