Processing residues e.g. dust, collecting box for e.g. grinder, has container comprising variation unit that varies size of collecting volumes, where container and variation unit are formed as single unit

摘要

The box has a container (8) comprising a variation unit (12) that varies the size of collecting volumes (14), where the container and the variation unit are formed as a single piece. The variation unit has two stable form states characterized by different collecting volumes. The variation unit is reversibly transferable between the form states by applying a minimum force. The variation unit has a folding unit provided for deformation. The container has two rigid areas (18, 24), where the area (18) is movable relative to the other area (24) by the variation of the variation unit.
