Abstract

A paint brush and method include a ferrule extending around and in contact with a plurality of bristles and a spacer apparatus positioned to space apart the plurality of bristles to provide at least one reservoir within the plurality of bristles. The spacer apparatus defines at least one opening extending through the spacer apparatus that allows fluid passage therethrough to the at least one reservoir to assist in removal of paint from the plurality of bristles when fluid is provided therein.

First claim

The invention claimed is:

1. A paint brush comprising:
a brush handle comprising a handle portion and an attachment portion, wherein the attachment portion defines at least one channel extending from a distal outlet opening to a proximal inlet opening located closer to the handle portion than the distal outlet opening;
a plurality of bristles extending from a distal bristle end region to a proximal bristle end region;
a ferrule extending around and in contact with at least a portion of the plurality of bristles at the proximal bristle end region; and
a spacer apparatus extending from a proximal end to a distal end and positioned to space apart the plurality of bristles at the proximal bristle end region to provide at least one reservoir within the plurality of bristles, wherein the spacer apparatus defines at least one opening extending through the spacer apparatus from the proximal end to the distal end, wherein the at least one opening of the spacer apparatus comprises a plurality of openings, wherein at least a portion of the plurality of bristles at the proximal bristle end region are coupled between the ferrule and the spacer apparatus, wherein the spacer apparatus is configured to restrict paint in the at least one reservoir from flowing through the proximal end of the spacer apparatus, and further wherein the spacer apparatus comprises one or more structures defining the plurality of openings, wherein the one or more structures comprise a honeycomb structure, a mesh, or a screen structure, wherein the one or more structures extend orthogonal to an axis extending between the proximal end of the spacer apparatus and the distal end of the spacer apparatus.

2. The paint brush of claim 1 , wherein the at least one opening of the spacer apparatus defines a larger area at the distal end of the spacer apparatus than at the proximal end of the spacer apparatus such that paint in the at least one reservoir is restricted from flowing through the proximal end of the spacer apparatus.

3. The paint brush of claim 1 , wherein the at least one opening of the spacer apparatus is sized such that paint in the at least one reservoir is restricted from flowing through the proximal end of the spacer apparatus.

4. The paint brush of claim 1 , wherein at least one of the spacer apparatus and the ferrule comprises a plurality of spacing elements extending between the spacer apparatus and the ferrule.

5. The paint brush of claim 1 , wherein the handle portion defines a void region proximate the proximal inlet opening to allow access thereto.

6. The paint brush of claim 1 , wherein the spacer apparatus comprises a valve configured to restrict paint in the at least one reservoir from flowing through the spacer apparatus.

7. The paint brush of claim 6 , wherein the valve comprises a one-way valve.

8. A paint brush comprising:
a brush handle comprising a handle portion and an attachment portion, wherein the attachment portion defines at least one channel extending from a distal outlet opening to a proximal inlet opening located closer to the handle portion than the distal outlet opening;
a plurality of bristles extending from a distal bristle end region to a proximal bristle end region;
a ferrule extending around and in contact with at least a portion of the plurality of bristles at the proximal bristle end region; and
a spacer apparatus extending from a proximal end to a distal end and positioned to space apart the plurality of bristles at the proximal bristle end region to provide at least one reservoir within the plurality of bristles, wherein the plurality of bristles define the at least one reservoir, wherein the spacer apparatus is contained within the ferrule such that the distal end of the spacer apparatus does not extend beyond the ferrule, wherein the spacer apparatus defines at least one opening extending through the spacer apparatus from the proximal end to the distal end, wherein the at least one opening of the spacer apparatus is sized such that paint in the at least one reservoir is restricted from flowing through the proximal end of the spacer apparatus, wherein at least a portion of the plurality of bristles at the proximal bristle end region are coupled between the ferrule and the spacer apparatus, and further wherein the at least one channel of the attachment portion and the at least one opening of the spacer apparatus define a passageway that allows fluid passage from the proximal inlet opening of the attachment portion to the at least one reservoir to assist in removal of paint from the plurality of bristles when fluid is provided into the proximal inlet opening of the attachment portion.

9. The paint brush of claim 8 , wherein the at least one opening of the spacer apparatus defines a larger area at the distal end of the spacer apparatus than at the proximal end of the spacer apparatus.

10. The paint brush of claim 8 , wherein at least one of the spacer apparatus and the ferrule comprises a plurality of spacing elements extending between the spacer apparatus and the ferrule.

11. The paint brush of claim 8 , wherein the handle portion defines a void region proximate the proximal inlet opening to allow access thereto.

12. A paint brush comprising:
a brush handle comprising a handle portion and an attachment portion, wherein the attachment portion defines at least one channel extending from a distal outlet opening to a proximal inlet opening located closer to the handle portion than the distal outlet opening;
a plurality of bristles extending from a distal bristle end region to a proximal bristle end region;
a ferrule extending around and in contact with at least a portion of the plurality of bristles at the proximal bristle end region, wherein the ferrule comprises at least one inner surface facing at least a portion of the plurality of bristles, wherein that at least one inner surface of the ferrule comprises a plurality of grooves to define a gap between the ferrule and the plurality of bristles; and
a spacer apparatus extending from a proximal end to a distal end and positioned to space apart the plurality of bristles at the proximal bristle end region to provide at least one reservoir within the plurality of bristles, wherein the spacer apparatus defines at least one opening extending through the spacer apparatus from the proximal end to the distal end, wherein the at least one opening of the spacer apparatus defines a larger area at the distal end of the spacer apparatus than at the proximal end of the spacer apparatus such that paint in the at least one reservoir is restricted from flowing through the proximal end of the spacer apparatus, wherein at least a portion of the plurality of bristles at the proximal bristle end region are coupled between the ferrule and the spacer apparatus, and further wherein the spacer apparatus is configured to restrict paint in the at least one reservoir from flowing through the proximal end of the spacer apparatus.

13. The paint brush of claim 12 , wherein the plurality of grooves are evenly spaced around the at least one inner surface of the ferrule.

14. The paint brush of claim 12 , wherein the ferrule comprises a seamless ferrule.

15. The paint brush of claim 12 , wherein at least one of the spacer apparatus and the ferrule comprises a plurality of spacing elements extending between the spacer apparatus and the ferrule.
