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.
Claims14
A method of making a brush adapted for applying a flowable fluid to a workpiece, comprising the steps of:
- assembling a plurality of elongated filaments formed of a heat-fusible synthetic material into a tuft of said filaments;
- securing together the proximal ends of the filaments in said tuft so as to define a brush head 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 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 to the filaments proximate the filament distal ends for selective application of the fluid to a workpiece.
