A collapsible container comprising:
- a peripheral side wall movable between extended and collapsed conditions;
- a dosed bottom at a lower end of the peripheral side wall and an opening at an upper end of the peripheral side wall;
- said peripheral side wall having at least three axial sections, with at least one relatively thin section located axially between upper and lower relatively thick sections;
- wherein at a transition area between the relatively thin section and at least one of the upper and lower relatively thick sections, the peripheral side wall is shaped to include a sideways oriented, substantially S-shaped cross section when the container is in its extended condition, and wherein said substantially S-shaped cross section includes a first radius and a second radius, and wherein said first and second radii have different wall thicknesses.
