A container (11) which can be carried on the back is equipped at the lower edge, on each side, with an outlet tube (13) which opens into a spreading pan (12) carried by it. To make the position of the spreading pans adjustable, the connection between the outlet tube and the respective spreading pan (12) and/or the container (11) is designed as a ball joint. The outlet tube passes through a joint ball (19; 26) which is mounted in a partially spherical seat (17). <IMAGE> |
