Abstract
A manual machine tool ( ) includes a vacuum device for dust removal ( ) situated in its housing ( ) and a blow-out connection ( ) installed after this. A dust collection box ( ), particulaily self-contained, can be attached in detachable fashion to the blow-out connection ( ) via its blow-in connection ( ). The dust collection box ( ) is airtight on all but two sides and has air-exit holes ( ) on the top side ( ) and a dustproof filter element ( )—especially a fluted filter—on the inside. The dust collection box is particularly secure against the unintentional escape of dust after the dust collection box is detached from the associated manual machine tool because a pair of sealing lips ( ) arranged as a separate part is provided inside the blow-in connection ( ), which pair of sealing lips ( ) is connected as a single part with closing flaps ( ) projecting into the interior of the dust collection box ( ).
