A collapsible container, formed from a blank of heavy paperboard or cardboard comprising four side walls interconnected with each other, first bottom wall means extending from the lower edges of a pair of the side walls adjacent to each other and inwardly foldable, second bottom wall means extending from the lower edges of another pair of the side walls adjacent to each other, a first score line on the first bottom wall means, a second core line on the second bottom wall means, and reinforcing members disposed on the opposite ends of the side walls. The carton as a whole may be very readily set up or collapsed by unfolding or folding the first and second bottom wall means over along the first and second fold lines.
