In a first stage, the flow of material occurs in a central peripheral position (40) with the flow area corresponding to a tubular component (9, 10). The flow area starts from the lower opening (7) of the container, up through the tubular component and then up through the upper powder mass, forming slanting lines (50) with intermittent transition from the shape of an upper edge line (21). - In a second stage, the flow area is divided into compartments, with the emptying movement commencing where the lower slanting line (50) touches the upper edge line (30) on the tubular component (9, 10). |
