A mounting collar is for supporting a vacuum cleaner filter bag in a mounted condition over a vacuum cleaner fill tube. The fill tube has a cylindrical outer surface. A panel of the mounting collar is configured to be attached to the filter bag. The panel has a first inner edge defining a first opening for receiving the fill tube. An elastomeric diaphragm of the collar extends across the first opening. The diaphragm has a second inner edge defining a second opening. The second inner edge is configured to be elastically stretched circumferentially about the fill tube and to be in contact with the cylindrical outer surface about the entire circumference of the cylindrical outer surface when the first opening receives the fill tube. A lobe of the diaphragm is defined by the second inner edge and a baseline. The baseline extends from a first point on the second inner edge to a second point on the second inner edge and is located entirely on the diaphragm.
