A dust container comprising a dust bag (10), a collar (11) fastened to the bag, and a flexible membrane (16) with a membrane opening (17), where the flexible membrane partly covers an inlet opening (15) that can be at least partly sealed by means of a guillotine arrangement having a plate-shaped element (21), which is provided with an opening and is moved parallel to the plane of the collar. The opening of the plate-shaped element is designed such that a rear part of the plate-shaped opening, as seen in a moving direction of the plate-shaped element from an open to a closed position, is provided with a forwardly extending portion (26) whose central section is place further forward, as seen in the moving direction, than the adjacent side parts of the plate-shaped opening. |
