The barrel (1) has walls (3) extended from bottom (2) to an upper edge of the barrel, where height of the walls is larger than breadth or depth of the bottom of the barrel. The bottom and the walls form a common injection mold component, and two injection points (7) are provided at the bottom. Axle supports (4) for an axle are provided close to the bottom of the barrel with running wheels. A hinge axle (6) serving hinge-like attachment of a cover is used as a handle of the barrel and provided at an upper end of each wall. |
