A collapsible container comprising:

• a roof;
• a base;
• two opposing end walls, each end wall comprising an upper and a lower end wall panel pivotally attached to said roof and said base respectively, said upper end wall panel being horizontally pivotally attached to said lower end wall panel to permit inward folding of each of said end walls;
• two opposing removable side walls fitting between said roof and said base;
• said end walls and said side walls being a twinned wall structure defined by inner and outer wall members made of plastic;
• wherein each of said side walls is partitioned into first, second, and third sequentially adjacent side wall panels, each of said side wall panels engaging said roof and said base along adjacent edges by complimentary tongue and groove means,
• wherein a groove in each tongue and groove means between said roof and said side wall panels has one or more sections dimensioned to permit upward displacement of said first, second and third side wall panels, so that said first, second and third side wall panels can be removed from said container when aligned with said one or more sections by disengaging said first, second and third side wall panels from the tongue and groove means between said base and said side wall panels;
• whereby said container is collapsible by removing said side walls and inwardly folding said end walls to draw said roof closer to said base.
