Patents Assigned to NICHIBOU CO., LTD.
  • Patent number: 10118059
    Abstract: The present invention provides a compact automatic fire extinguishing equipment that can be installed near an object of fire extinguishing for which there is limited space therearound for a long term in a state of maintenance-free and that can extinguish a fire immediately on the occasion of a fire. The fire extinguishing equipment consists of a fire extinguishing agent 14 and a sealed container 12 filled with the fire extinguishing agent 14. And the fire extinguishing agent 14 is comprised with a compound that is liquid at 25 degrees Celsius (room temperature) at least and that has a boiling point of at least 75 degrees Celsius or less, having fire extinguishing effect. The container 12 is formed with lamination of gas barrier layer 16 and the thermoplastic resin layer 20, and the gas barrier layer 16 consists of ethylene-vinyl-alcohol copolymer resin (ethylene vinyl alcohol copolymer: EVOH).

  • Patent number: 9962568
    Abstract: The present invention provides an automatic fire extinguishing device that can detect a fire at the temperature lower than 120 degrees Celsius and that can be installed for a long term in a state of maintenance-free. The fire extinguishing device consists of a pressure resistant container filled with the extinguishant and the pressurization agent, the container valve attached to the opening of the pressure resistant container, the fire detection tube connected to the container valve. And the fire detection tube is formed with the lamination of the tubular base resin layer and the gas barrier layer, the base resin layer is made of the thermoplastic resin and the gas barrier layer is made of ethylene vinyl alcohol copolymer resin (EVOH resin).
