摘要

The vessel with a standing surface consists of one or more blanks of flexible flat material (a,c) which are such that in the final stages of assembly defined points or surfaces can be brought together by folding, bending or curving without special technical ability. The vessel resulting from this procedure can be fixed by suitable devices. The fixing during the final assembly is reversible and dispenses with adhesive. The fixing may be in the form of press-studs, hooks or slide fasteners.
