This invention relates to a dust container comprising a bag of air pervious material the opening of the bag being covered by a plate (12a, 12b) of comparatively stiff material. The plate has an inlet opening which is connected to an inlet sleeve (18) of the vacuum cleaner. The inlet opening is provided with a first and a second elastic membrane (14 and 15 resp.)each having an opening for taking up the inlet sleeve, two opposite flaps (16a,16b) of comparativeley stiff material being arranged between the membranes (14,15) so that they at least partly cover the openings of the membrane. One side of the first flap (16a) is provided with a third elastic membrane (17) which, when the container is not used, at least partly overlaps or is overlapped by the second flap (16b). <IMAGE> |
