ABSTRACT:
A vacuum bag for use with a vacuum device having a dirty air vacuum inlet has a conventional self-sealing collar including a pair of apertured planar panels, an apertured resilient membrane therebetween, and a finger extending at least partially across the outer panel aperture. However the collar is made self-aligning with a vacuum inlet by adding a third planar panel disposed parallel to and outwardly of the pair of panels. The third panel defines a respective third aperture therethrough configured and dimensioned for receipt of a vacuum inlet therethrough and aligned with the apertures of the pair of panels. The third aperture is of a thickness to facilitate blind placement of the collar on a vacuum inlet. In a combination of the bag and a vacuum device, the dirty air inlet extends through the three panel apertures as well as the membrane aperture of the collar.
