Abstract: The invention relates to a sealed and thermally insulating tank for storing fluid, comprising, from the outside to the inside of the tank, a secondary thermally insulating barrier and a secondary sealing membrane, the secondary sealing membrane being secured to the secondary thermally insulating barrier, a primary thermally insulating barrier resting against the secondary sealing membrane and a primary sealing membrane resting against the primary thermally insulating barrier, the tank comprising a duct that extends along a longitudinal direction, the duct being delimited on one hand by the secondary thermally insulating barrier and on the other hand by the secondary sealing membrane, a bottom of the duct being at least in part formed by the secondary thermally insulating barrier, the tank further comprising a pressure-drop stopper that is arranged in the duct and extends between the bottom of the duct and the sealing membrane.

Abstract: A sealed and thermally insulating tank has a thermally insulating barrier and a sealing membrane. The tank has a channel extending in a longitudinal direction along the sealing membrane. The thermally insulating barrier forms a bottom of the channel. The tank further has a closure member that is a flexible film. The flexible film has a first fastening zone extending transversely to the longitudinal direction of the channel and fastened to the bottom of the channel and a second fastening zone extending transversely to the longitudinal direction of the channel and fastened to the sealing membrane. The flexible film has a closure portion interposed between the first fastening zone and the second fastening zone. The closure portion closes the channel in order to create a loss of pressure in the channel.
