Abstract

Abstract A sponge collection device comprising, a backing sheet of flexible material having a front surface, a rear surface, a pair of side edges, and a pair of end edges connecting the side edges. The device has a plurality of pockets progressively disposed on the front surface of the backing sheet intermediate the end edges. The pockets comprise a flap of flexible material having a pair of side edges, and an upper edge extending between the side edges, with side portions of the flap adjacent its side edges being joined to the backing sheet adjacent the side edges of the backing sheet. The upper edge of the flap defines an opening intermediate the flap and backing sheet to receive sponges, with a lower portion of the flap being joined to the backing sheet along a line intermediate the side portions of the flap. The joinder line extends upwardly from each of the flap side portions toward a raised central portion of the joinder line.
