Claims

[Scope of utility model registration request]

(1) In a low-temperature storage tank that has a double shell structure of an inner tank and an outer tank, and a cold insulator is filled between the inner and outer tanks, an elastic bracket is installed to cover at least the outer surface of the inner tank side wall and the outer surface of the inner tank roof. 3. A double-shell cryogenic storage tank characterized in that the outer surface of the elastic blanket is covered with an airtight flexible membrane plate and the elastic blanket is attached to the inner surface of the outer tank side wall.

(2) Scope of Utility Model Registration Claim Paragraph 1 states that the airtightness is visible through the outer tank and the cold insulation layer so that the space surrounded by the inner tank and the airtight flexible membrane plate communicates with the outside of the tank. A double-shell low-temperature storage tank characterized by having a discharge pipe that opens into a membrane plate.
