<p>The spinning container has a fixed base (1) on which are fixed support rollers (4). The cover (6) is protected at the top by a metal edge (7) with a rounded joint (8). A movable end (9) has a bent over edge (10), guided by pantographs (12), thrust upwards by a helicoidal spring (14) to hold the edge horizontal. There is a fixing for the spring and pantograph bases as near the ground as possible, between the rollers. A part (28) at the base keeps out foreign bodies from the base (1) when the pot is moved on the rollers.</p> |
