PCT No. PCT/CH93/00059 Sec. 371 Date Nov. 9, 1993 Sec. 102(e) Date Nov. 9, 1993 PCT Filed Mar. 8, 1993 PCT Pub. No. WO93/17918 PCT Pub. Date Sep. 16, 1993.A container made of a synthetic material, e.g., a bottle (10), comprising a closed bottom wall (11) and an opening (12) in the upper portion opposite the bottom wall. The container is produced according to a blow moulding, stretch blow moulding or thermoforming method, and its wall (9) comprises at least one fold line (13) consisting of a narrow linear area (13a) of said wall, in which the synthetic material has a different physical structure, whereby it is less plastically deformable but has at least as much tensile strength as the rest of the wall (9). This structural modification is obtained by mechanical or thermal processing or by exposure of the area in question to suitable particle radiation. The resulting bottle is readily foldable with a view to disposal after use.
