AbstractA disposable vacuum cleaner dust bag includes a porous sheet defining a dust collection chamber having an inlet, and a substantially rigid collar secured to the sheet around said inlet. The collar provides a generally circular opening and has at least a pair of peripherally spaced radially pivotable further portions disposed about the opening and extending radially inwardly further than the remainder of the collar when the pivotable portions and the collar remainder are in the same plane. An elastic diaphragm on the collar provides a generally circular opening smaller than the opening in the collar. The collar is adapted to mount on a connector having a generally cylindrical outlet having an end through which the air is delivered by a vacuum cleaner and which provides peripherally spaced outwardly extending projections. The collar is adapted to be installed, maintained in an installed position, and removed with the pivotable portions aligned with the projections. In the installed position the collar, the diaphragm and the pivotable portions are adapted to extend past the projections at the side thereof remote from the end, with the pivotal portions at least indirectly engaging the sides of the projections remote from the end at an angle to releasably secure the collar on the connector in the installed position. The diaphragm is adapted to extend into engagement with the surface of the connector on both sides of the projections to provide an airtight seal with the connector when the collar is in the installed position.
