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. A second apertured resilient membrane may be disposed between the third panel and the pair of panels, the second membrane aperture being sized to enable formation of an uninterrupted 360.degree. seal with a vacuum inlet when the collar is disposed thereon.
