A collapsed, pop-open and disposable debris collector formed of a semi-rigid blank the composition of which has a folded elastic memory, the collector forming interconnected rear abutment, side walls and a bottom, the side walls lapping the rear abutment wall in part in a collapsed configuration; permanent adhesive on the rear wall, securing a portion of the lapping side walls to the exterior of the rear abutment wall and spring-like foldable abutment retaining tabs projecting from each side wall, extensible upon setting up to engage the interior of the rear wall upon pop-opening of the collector from collapsed to pop-open utility configuration; the collector having an integral handle at the rear and a no-spill lip at the forward open end and pressure sensitive adhesive which is coextensive with the no-spill lip to coact therewith in the utility mode. The debris collector is readily adapted to stack packaging.
A collapsed, pop-open and disposable debris collector formed of a crisp blank, the composition of which is such that upon folding it tends to rebound to unfolded state, said blank upon folding having a bottom and an interconnected abutment rear wall and opposed side walls;
The debris pop-open collector of 1 or 2 wherein a segment of pressure sensitive adhesive is exposed upon the exterior of the collector bottom adjacent its open end whereby to provide an anchor of the collector to supporting surfaces to be cleaned allowing the sweeping function to be effected without hands-on gripping.
The pop-open debris collector of either 1 or 2, wherein the abutment rear wall defines a collapsible handle extension which in the utility configuration unfolds to project rearwardly of the abutment rear wall.
A method of forming a disposable pop-open debris collector from a semi-rigid crisp blank the composition of which is such that it tends to rebound after folding to an unfolded state, wherein the collector defines a flat bottom bounded by open and closed ends, the ends being connected by upright side walls comprising the steps of:
