Abstract
A permanent mounting assembly for a vacuum cleaner filter bag includes a plastic collar stitched to the porous body of the vacuum cleaner bag around the inlet opening thereof. The bag is mounted on the exterior surface of a projection on the vacuum cleaner housing. The exterior surface of the projection is provided with an annular groove. An interior rib on the collar is positioned within the groove to mechanically lock the bag on the projection of the housing. A nonelastic tie strap is positioned around the rib to permanently secure the rib in place and to provide a permanent fluidtight connection between the collar and the projection on the housing. The collar is provided with a band which is folded back to conceal the stitching, providing an attractive, neat appearance.
