Abstract

The invention provides for an improved article of manufacturing, being a utility brush that is designed to be made from material that minimizes abrasion to surfaces. This brush is made from materials excluding metal and other materials that can cause abrasion to surfaces upon the utility brush making physical contact with those surfaces. The utility brush being further designed to be made of material that excludes adhesives, where adhesives can be vulnerable to decomposition caused by physical contact with chemical solvents that could be applied to the utility brush or to the surfaces. The brush can be further dimensioned and/or customized, to brush surfaces located within oddly dimensioned and/or difficult to access spaces, including small and/or narrow spaces and crevices.

Dependent claims

A utility brush, including:

a handle being made from a material including polypropylene;
a bristle sleeve including a backing layer and pile of bristles,
said backing layer being made from a material including polypropylene and having an interior and an exterior surface, and wherein said interior surface of said backing layer being configured to be attachable to said handle;
and wherein said exterior surface of said backing layer being attached to said pile of bristles;
said bristle sleeve being configured to be wrapped around said handle so that said interior surface of said bristle sleeve is in physical contact with an outer surface of said handle;
and wherein
said backing layer of said bristle sleeve being attached to said outer surface of said handle at a plurality of points, spatially separated from each other, along said handle and said backing layer, wherein one or more groups of different ones of said plurality of points are at a set spatial relationship with each other.

A method for making a utility brush, including:

providing a handle having an exterior surface and being made from a material including polypropylene;
providing a bristle sleeve including a backing layer and a pile of bristles;
and wherein
said bristle sleeve being configured to be wrapped around said handle so that said interior surface of said bristle sleeve is in physical contact with said exterior surface of said handle;
and wherein
said backing layer being made from a material including polypropylene and having an interior surface and an exterior surface, and wherein said interior surface of said backing layer is configured to be attachable to said handle;
and wherein said exterior surface of said backing layer is attached to said pile of bristles;
and
directing energy towards a plurality of points, each of said points being spatially separated from each other along said backing layer and said handle, causing heating and attachment between said exterior surface of said handle and said interior surface of said backing layer, at said points, and wherein one or more groups of different ones of said plurality of points are at a set spatial relationship with each other.
