TODAY’S PATENT – VACUUM CLEANER DIRT CUP AND SEAL
The said invention (US8402599B2) was invented by Christopher M. Charlton, Raymond P Kawolics on 1st September 2010. Currently; it stands assigned to Techtronic Floor Care Technology Ltd.
The invention concerns dirt cups for vacuum cleaners, specifically focusing on seals. A dirt cup collects debris during vacuuming. Once full, it’s detached, emptied, and reattached, eliminating the need for replaceable vacuum bags.
A vacuum cleaner’s dirt cup features a container with an open bottom, a lid, a tube, two chambers, and a seal. The lid, which covers the bottom when closed, has an aperture and can be opened to empty the container. The seal, attached to the lid by a post fitting into the aperture, sits between the lid and tube when closed, blocking airflow between the two chambers.
