SEALED AND HEAT-INSULATING RESERVOIR Russian patent published in 2024 - IPC F17C13/00 F17C13/02 B63B25/16 

FIELD: manufacturing technology.

SUBSTANCE: group of inventions relates to sealed reservoir (100). Reservoir comprises a plurality of reservoir walls, including first wall (106) and second wall (104), which are parallel to first direction (101), and two end walls (108), which are perpendicular to the first direction and connect the first wall and the second wall. Each wall of the reservoir in series comprises, in the direction of thickness from the outer side to the inner side of the reservoir, a heat-insulating barrier held on the corresponding bearing wall, and a sealing membrane resting on the heat-insulating barrier. Sealing membrane of each of first wall, second wall and end walls comprises a row of corrugations (118), parallel to each other and located at right angles to transverse angles (107), formed by first wall or second wall and end walls. Parallel corrugations are spaced apart so as to form in a direction parallel to the transverse angles: a plurality of identical constant intervals (120), wherein each constant interval is formed between two adjacent corrugations, and one separate interval (122), different from the constant interval.

EFFECT: simplified reservoir fabrication.
