Waste transfer and disposal system for bagless vacuum cleaners
View Patent ↗A system for the collection and containment of vacuumed dust and debris, and more particularly to waste disposal bags for placement over a portion of a bagless vacuum cleaner, and into which the waste contents of the vacuum cleaner are emptied. The system includes a mouth with a projecting lip, a non-projecting lip and a light tack adhesive strip on the projecting or non-projecting lip. When the mouth is constricted about a portion of the bagless vacuum cleaner, the light tack adhesive strip adheres the bag for temporary affixment to the vacuum cleaner. The projecting lip serves as a flap that is folded over the mouth to seal the bag after the filled bag is separated from the vacuum cleaner.
1. A waste transfer and disposal bag for bagless vacuum cleaners comprising:
(1) a bag including an opening with at least a first lip, an inner surface, an outer surface, a front side with a maximum width, a back side, a bottom edge, and, a projecting flap opposite from and superior to the first lip, the projecting flap extending beyond the opening, the projecting flap including a flap width, at least an inside surface, and wherein an uppermost portion of the projecting flap defines a top edge of the bag;
(2) a first adhesive strip with a peel away backing on the inside surface of the projecting flap, the first adhesive strip configured to span the flap width, the first adhesive strip located above the first lip of the bag, and the first adhesive strip adapted to temporarily form a first seal between the bag opening and a disconnected dust collection canister of a bagless vacuum cleaner, and, wherein the projecting flap is flexibly conformable and adhesively sealable around the dust collection canister; and,
(3) an elastic member adapted to provide a circumferential seal about plural sizes of dust chutes of bagless vacuum cleaners, the elastic member forms an elastic annulus, the elastic annulus is stretchable over portions of the dust collection canister, and, the elastic annulus is configured to constrict to a relaxed state when the bag is not attached to the dust collection canister, and the elastic annulus in the relaxed state includes at least a maximum width transverse the front side of the bag less than one-half the maximum width of the front side of the bag in order to prevent escape of particulate matter.
2. The bag according to claim 1 , further comprising a second adhesive strip inferior to the lip of the opening.
3. The bag according to claim 1 , further comprising a pressure sensitive adhesive.
4. The bag according to claim 1 , further comprising a bag closure formed when the projecting portion of the bag is adhered to another portion of the bag to occlude the bag opening.
5. The bag according to claim 1 , further comprising further comprising gathers on the projecting flap.
6. A waste transfer and disposal bag for bagless vacuum cleaners comprising: (1) a bag including an opening including at least a first lip, the bag including an
inner surface, an outer surface, a front side, a back side, a bottom edge including a maximum width, and, a projecting flap opposite from and superior to the first lip, the projecting flap configured to extend beyond the opening, the projecting flap including a second width, at least an inside surface, and wherein a top portion of the projecting flap defines an uppermost edge of the bag;
(2) a first adhesive strip with a peel away backing on the inside surface of the projecting flap, the first adhesive strip configured to span the second width, the first adhesive strip located above the first lip of the bag, and the first adhesive strip adapted to temporarily form a coupling between the bag opening and a dust chute of a disconnected dust collection canister of a bagless vacuum cleaner wherein the
projecting flap is flexibly conformable and adhesively sealable around the dust collection canister; and,
(3) an elastic annulus adapted to provide a continuous circumferential seal around plural sizes of dust chutes, the elastic annulus is stretchable over portions of the dust collection canister, the elastic annulus includes a relaxed state with a maximum width when not attached to a dust chute, and the maximum width of the elastic annulus in the relaxed state is less than one-half the maximum width of the bottom edge of the bag in order to prevent escape of particulate matter.
7. The bag according to claim 6 , further comprising a second adhesive strip inferior to the lip of the opening.
8. The bag according to claim 6 , further comprising a bag closure formed when the projecting portion of the bag is adhered to another portion of the bag to occlude the bag opening.
9. The bag according to claim 6 , further comprising gathers on the projecting flap.
10. The bag according to claim 6 , further comprising a pressure sensitive adhesive.
