SEMIRIGID FOLDING CONTAINER Russian patent published in 1998 - IPC

FIELD: materials handling and storage. SUBSTANCE: proposed semiring container with folding part is designed for storing carbonized liquids. It consists of many rhomboid-shape panels forming truncated cone. Panels are curved to arc relative to connecting bed of truncated cone in cross or longitudinal direction. Panels counteracting the expansion caused by inner pressure of container are able to expand crosswise to provide folding of foldable part under of longitudinal folding force. Panels resists to expand from folder state. EFFECT: enhanced storage of carbonized liquids. 15 cl, 25 dwg
