20090139044 | Corrugated Bristle Brush - A brush including layers of bristles used with a handle. Plates, with bristles connected to a base at one end, are retained by the handle. Certain stackable plates may also be interconnected by a set of hinges. Plates can be of a unitary plastic construction and can be stacked or folded upon one another to form layers of plates with bristles. A corrugated layer is adjacent to a first plate or between two plates. The corrugated layer has a base and corrugated bristles extending from an end of the base, with the corrugated bristles preferably shaped in alternating ridges and grooves. The corrugated layer is stiffer than an adjacent plate of bristles and assists with liquid retention of the brush. Recesses or holes in the ridges of the corrugated bristles can aid with liquid retention in the brush before applying the liquid on a surface. A method of making a brush with layers of bristles can include forming a first plate having a series of bases connected to a plurality of bristles, stacking bases of the first plate in layers, attaching the stacked bases of the first plate to a handle, and forming and attaching a corrugated layer to be adjacent to the first plate. | 06-04-2009 |
