Claim:
A foldable sheet formable into a basket for transportation of heavy weight items comprising a lateral surface, a bottom and a handle, said foldable sheet comprising: a plurality of folding lines; a pair of substantial first sectors, each said first sector formed having a trapezoidal shape with a top portion being more narrow than a bottom portion, a pair of second sectors, each said second sector formed having a trapezoidal shape with a top part being more narrow than a bottom part, said pair of the first sectors and said pair of the second sectors joined to each other by joining sectors, each said joining sector formed having substantially triangular configuration, the pair of first sectors, the pair of second sectors and the joining sectors defining the lateral surface of the basket; a pair of lower sectors, each said lower sector joined to one of said second sectors, the lower sectors defining the bottom of the basket; a pair of central flaps, each said central flap extending between a proximal end connected to the lower sector and a distal end, with the proximal end being more narrow than the distal end, said proximal end joined to the lower sector at a respective folding line, a pair of side portions connecting the proximal and distal ends, a pair of protrusions extending outwardly from the side portions, said central flaps defining a partition separating the basket into two housings, the handle is formed by a part of the partition situated outside of the housings; and grooves extending longitudinally through said first sectors, said grooves disposed in central regions of said first sectors and spaced from the folding lines defining said first sectors, said protrusions being inserted into and extending outwardly from said grooves when the basket is in use.
