The bottom has a back (7) located between the side pieces (3,3') centrally which extends inclinedly upwards and backwards and divides the bottom into two large surfaces (8,8'). The large surfaces each incline both forwardly and to the side. In the area of the bottom front edge (5) is arranged another frame (9) which extends unbrokenly along the front edge and connects to the front parts (10,10') of the first frame (6) and which has a height comprising only a fraction of that of the first frame. |
