Abstract
A sealable debris bag includes a bag body having an opening, and a plate member attached to the bag body proximate the opening. First and second portions of the plate member are pivotable along a fold-line so that the first portion is engageable with the second portion to substantially seal the opening. A tab on one side of the fold-line engages a notch on the other side of the fold-line to secure the device. The fold-line can be formed in the plate member, to define the first and second portions where the portions are contiguous, or can be formed in the bag body where the portions are non-contiguous. The opening may be formed in a flexible lateral wall of the bag body, or alternately, in an end portion of the bag body. A complimentary alignment structure on plate member mates with an alignment structure on a vacuum to ensure proper alignment of the debris bag on the vacuum.
