Brush and method of making same
First Claim
1. A brush adapted for applying a flowable fluid to a workpiece, said brush comprising:
- a plurality of elongated filaments formed of a synthetic heat-fusible material and disposed so as to define a tuft of said filaments, said filaments being heat-fused together to form at their proximal ends a head section comprising a non-planar heat-fused wall peripherally bounding an opening, and said filaments being freely movable relative to each other at their distal ends opposite said proximal ends; and
a fluid distribution channel in communication with said head opening and extending longitudinally along said brush from said head section toward said filament distal ends, said channel being peripherally bounded by a substantially flexible membrane and having an aperture defined at an end of said channel opposite said head section so that fluid fed to brush at the head section is flowable through said head section opening, into and along said distribution channel and through said aperture onto said filaments proximate their distal ends for selective application to a workpiece, said flexible channel membrane being formed of the same material of said filaments.

Abstract
A brush adapted for selective application of a flowable fluid to a workpiece is formed in its entirety of a heat fusible synthetic material and includes a hollow head section, a plurality of bristles depending from the head section, and a fluid distribution channel defined by a flexible membrane and extending substantially axially within the radial interior of the bristles from the head section of the brush toward the free ends of the bristles. Fluid fed to the brush head is delivered through the head section to the distribution channel and is discharged from the channel onto the bristles within the interior of the bristle tuft and proximate the bristle ends for facilitated distribution among the bristles and ready application to a workpiece by the user.

9. A method of making a brush adapted for applying a
assembling a plurality of elongated filaments formed of a heat-fusible synthetic material into a tuft of said filaments; -
heating the proximal ends of the filaments in said tuft so as to form a heat-fused wall defining a head section at the proximal end of the tuft; and heating a peripherally-interior portion of said tuft so as to form a substantially flexible membrane extending within and substantially axially along the tuft from said head section toward the distal end of the tuft and thereby define a fluid distribution channel in said brush for feeding fluid through said brush from the head section to the filaments proximate the filament distal ends for selective application of the fluid to a workpiece. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A brush adapted for applying a flowable fluid to a workpiece, said brush comprising:
-
a plurality of elongated filaments formed of a synthetic heat-fusible material and disposed so as to define a tuft of said filaments, said filaments being heat-fused together to form at their proximal ends a head section comprising a heatfused wall peripherally bounding an opening, and said filaments being freely movable relative to each other at their distal ends opposite said proximal ends; and a fluid distribution channel in communication with said head opening and extending longitudinally along said brush from said head section toward said filament distal ends, said channel being peripherally bounded by a substantially flexible membrane and having an aperture defined at an end of said channel opposite said head section so that fluid fed to said brush at the head section is flowable through said head section opening, into and along said distribution channel and through said aperture onto said filaments proximate their distal ends for selective application to a workpiece, said flexible channel membrane being formed of the material of said filaments by heat fusing of at least some of said filaments.
