Abstract
A canister vacuum cleaner includes a dust bag mount for mounting a dust bag with a collar onto the vacuum cleaner. The bag mount includes a mounting plate with a circular aperture. The dust bag collar includes an aperture that, upon installation of the collar, is aligned with the aperture in the mounting plate. Raised structure surrounds the aperture in the mounting plate and extends into the aperture in the collar upon installation providing a seal between the mounting plate and collar. The raised structure includes ramps and inclined surfaces to bend and lift the dust bag collar over the raised structure during its installation and removal. This structure also serves to index and retain the collar once it is installed and to seal the space between the installed dust bag collar and the mounting plate. A pair of channels are provided at the sides of the mounting plate for holding and guiding the edges of the dust bag collar during its installation and removal. A ramp is provided in each channel which acts to bias the dust bag collar against the mounting plate upon the installation of the dust bag. The channels are also sloped or angled relative to the mounting plate to reduce the stress imparted to the dust bag collar during its installation and removal and to move the dust bag collar against the mounting plate once the collar is installed. The dust bag collar includes a gripping tab and an aperture in the gripping tab to facilitate the removal of the dust bag collar from the bag mount.
