  • Patent number: 4800614
    Abstract: A disposable bag filters dirt particles and the like from exhaust air of a hand-held vacuum cleaner. The motor housing of the vacuum cleaner receives a conventional reusable bag thereon and an adaptor facilitates changeover of existing vacuum cleaners to accommodate the disposable bag. A reinforcing member is provided on the disposable bag and is dimensioned for a friction fit with the adaptor. Another preferred embodiment incorporates a seal member into the assembly to enhance the sealing integrity between the adaptor and disposable bag.
