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.
