Patent ID: 7156250

Claim:
A collapsible, tub-shaped container for erection on a support, comprising: a base ( 1 ) of flexible flat material with a frame construction, side walls ( 2 a , 2 b ) of flexible flat material and having a frame construction, wherein outer contours of the side walls ( 2 a , 2 b ) are constructed to be substantially congruent with or smaller or larger than outer contours of the base ( 1 ) and to be foldable into or onto the base ( 1 ); connecting walls ( 3 a , 3 b ) between the side walls ( 2 a , 2 b ); frame elements ( 4 ) disposed in the side walls ( 2 a , 2 b ) and the base, said frame elements, at least in a center longitudinal portion (A), comprising flexible spring rod members ( 5 a , 5 b ) which are arranged to extend or intersect in outer edges to form in common with other portions of the frame elements ( 4 ) a figure-eight-shaped course, a curved element connecting the side walls ( 2 a , 2 b ) together at an upper side at each of the front and the back; wherein a first side wall ( 2 a ) of the two side walls ( 2 a , 2 b ) can be folded over or pivoted onto the base ( 1 ) at an outer side thereof about a pivot axis or fold axis ( 8 ) extending longitudinally in an edge region, wherein with simultaneous drawing in and turning in of the curved elements ( 6 a , 6 b ) of the respective connecting walls ( 3 a , 3 b ), the second side wall ( 2 b ) can be folded onto the first, folded-over side wall at the outer side of the base ( 1 ) about a fold axis ( 9 ) extending longitudinally in an edge region and wherein by diagonal twisting and subsequent folding together of a thus-formed one stack half ( 10 ) onto another stack half, said stack halves are collapsible in a substantially congruent manner.
