<p>A vacuum cleaner bag (8) comprises an air-permeable bag (10) that is fastened to a plastic flange (9). The plastic flange (9) is provided with a support opening (11) for introducing a connection fitting (5, 5') of a vacuum cleaner (1). The support opening (11) is provided with a peripheral seal (13, 14) made of an elastic material. In order to facilitate the introduction of connection fittings (5, 5') that have different outer diameters (19, 19'), the seal (13, 14) is dimensioned in such a way that the inner diameter (22) of the seal (13, 14) is smaller than the minimum diameter (19') of the connection fitting (5') to be accommodated, whereas the outer diameter (25) of the seal (13, 14) is larger than the maximum diameter (19) of the connection fitting (5) to be accommodated. The present invention advantageously implements a dust bag flange that reliably accommodates and seals fittings with different diameters.</p> |
