Abstract
A removable dust collecting container for professional and household vacuum cleaners. The container is closed with a dust filter embodied as a cover, whereby between the dust collecting container and the cover-like filter, a soft-elastic seal is arranged. The filter is embodied in a frame configuration, and projects in a positively connecting manner into the opening of the dust collecting container. The seal is arranged tangentially between the inner surface of the dust collecting container and the outer surface of the filter which projects or extends into the dust collecting container. The filter may be embodied as a double filter, including a coarse filter on the inlet side and an immediately subsequent filter embodied as a fine filter.
