Abstract
A pipe arrangement (40) consists of two nested pipes (60, 62) and a nozzle head (68, 76) on their bottom ends. This nozzle head is located within the diameter of the pipe arrangement (40) and does not protrude radially beyond its diameter. The pipe arrangement can thus be slipped through a guide opening (7) of a guide device (1) into a container holding powder or can be pulled out completely of the guide opening (7), without a need for disassembly of parts of the device. The guide device (1) contains preferably a container lid (3) that can be set on the container (6). Provided on the pipe arrangement (40) is a stop (44) that can be fastened on said arrangement at various heights and through the adjustment of which the immersion depth of the pipe arrangement (40) in the container can be adjusted.
