Abstract
A filter bag for a vacuum cleaner possesses a substantially plate-shaped connection member with a stationary two-part base body and a sliding door arranged between the two layers of the base body. The layers of the base body have aligned passage openings and the sliding door has a through opening, which in the open position of the sliding door is aligned with the passage openings. In the closed position the sliding door shuts off the passage openings. The base body has at least one abutment element, which fits into an abutment recess in the sliding door, the rim of the abutment recess constituting a terminal abutment striking against the abutment element at least in the closed position of the sliding door.

A filter bag for a vacuum cleaner comprising:
- a filter bag body, said filter bag body being formed with an inlet opening;
- a base unit attached to said filter bag body adjacent said bag body opening, said base unit having two spaced apart body layers, said body layers each being formed with an opening, said body layer openings being concentric with said bag body opening;
- a door slidably disposed between said body layers, said door having a first section formed with a door opening that can be selectively positioned in alignment with said body layer openings to place said door in an opened position and said door being further adapted so as to move said door opening out of alignment with said body layer openings so that a second section of said door is located substantially between said body layer openings to place said door in a closed position;
- and
- an abutment element attached to one said body layer and positioned to extend into said door opening when said door is moved to said closed position.
