FIELD: packages, particularly plastic vessels for food and other product storage.
SUBSTANCE: collapsible vessel comprises several collapsible sections arranged at an angle to each other. Each section is inclined to vertical line. Vessel has fold areas arranged between adjacent sections and adapted for flexible section movement between opened position when vessel is in erected state and folded position when vessel is in collapsed state. Fold areas restrict section movement between erected vessel and collapsed vessel states or in any other intermediate state in which said fold zones are in opened positions.
EFFECT: increased rigidity of erected vessel and compactness in empty state, as well as improved tightness.
