Abstract (en)
Disposable filter bag for a vacuum cleaner, comprising two sheets (1, 2) of flexible filter material, which are arranged on top of each other and joined together along their perimetral edge, or in the vicinity thereof, there being envisaged means for joining said bag to the suction pipe of a vacuum cleaner; the perimetral edge (101) of said bag is a convex closed line, along the greater part of which it is possible to define wide-angle adjacent sections (111, 121) so that the axial expansion of the bag caused by the entry of the sucked-in air allows at the same time radial expansion thereof.
