Abstract
A vacuum filter bag includes an inlet flange and gasket, a clamp positioned adjacent the inlet flange, and a plug. The clamp is operable to engage the inlet port of a canister vacuum when the filter bag is mounted in the vacuum and keeps the filter bag securely attached to the vacuum inlet. The clamp is also operable to engage the plug and keep the plug in place to close the filter bag inlet after use of the bag. The filter bag reduces user exposure to dust and debris captured with a canister vacuum.
Claims20
A vacuum filter bag comprising:
- a flexible front layer;
- a flexible back layer;
- wherein the flexible front layer and the flexible back layer are attached together to form a filter bag;
- wherein the filter bag comprises filter media of a porosity sufficient to filter dust from air flowing through the filter media;
- a front layer opening formed in the filter bag front layer;
- an inlet flange attached to the filter bag front layer at the front layer opening;
- an inlet gasket attached to the inlet flange;
- a filter inlet opening formed in the inlet gasket;
- a plug which is attached to the inlet flange by a first flexible connector;
- wherein the plug is sized and configured to engage the filter inlet gasket to thereby close the filter inlet opening;
- a clamp which is connected to the inlet flange by a second flexible connector;
- wherein the clamp is secured to the inlet flange in a position adjacent the filter inlet opening;
- wherein the clamp is operable to grip a vacuum inlet when the filter bag is attached to a vacuum such that a vacuum inlet extends through the filter inlet opening;
- and
- wherein the clamp is operable to grip the plug and thereby hold the plug in a position wherein the plug closes the filter inlet opening.
