A container (1) comprising a flexible body (2) which is collapsible and erectable, said body having a base (3) and a side wall (4), and stiffening means to stiffen the flexible body wherein the side wall (4) of the container (1) is arranged to assume a substantially cylindrical configuration when the container (1) is filled and the stiffening means comprises a unitary sleeve (5) of resiliently deformable material. The stiffening means is resiliently deformable about vertical axes, and is formed of a corrugated plastics material (30). The side wall (4) of the flexible body (2) is formed as an endless loop, for example as a unitary tubular or endless belt-shaped piece (12; 13). The container is especially resilient to bursting or rupturing and is ideal for many materials including liquids. |
