The container comprises a sheath of flexible synthetic material with a perforated structure. At least two opposed longitudinal zones are reinforced to provide rigidity for these zones relative to the rest of the wall of the sheath. The reinforced zones assure are paralleli-piped shape for the sheath. The strands which form the sheath are provided at greater density at the reinforced zones than elsewhere in the sheat. The sheath is formed of longidutinal strands connected by transverse strands. |
