Brush with stapled tufts

Abstract

A bristle brush has a head with a multiplicity of closely spaced recesses in one surface thereof and in which are disposed bristle tufts of U-shaped configuration which extend outwardly thereof. The tufts are comprised of multiple bristles and have a bight portion disposed adjacent the bottom of the recesses and vertically extending leg portions. Staples are disposed between the leg portions of the tufts and pressing the bight portions downwardly in the recesses. The staples have a body portion of generally rectangular cross section and of greater length than the diameter of the recesses. A multiplicity of ribs are provided on at least one side surface and extend transversely thereof. The ribs are spaced apart in the vertical direction a distance at least three times the width of the ribs, and the ribs are of substantially lesser height than the thickness of the body portion. At least some of the ribs are embedded in the material of the head about the recesses.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to brushes and, more particularly, to brushes using an improved staple to secure the bristle tufts in recesses in the head of the brush. [0002] Brushes are used in many applications for seemingly countless tasks. In come cases, brushes are designed for specific applications, such as toothbrushes for dental hygiene. Other brushes have more generic uses, such as a typical scrub brush. Brushes typically utilize a multiplicity of bristles bunched together to form a tuft. The tufts are anchored in tuft holes located in the brush head. Typically, numerous tufts / tuft holes are located on the brush head and the number and locations vary depending upon the design. In many cases, a staple is used to anchor the tuft into the tuft holes on the brush head. [0003] A common practice is to use a flat or rectangular piece of wire cut to a specified length as the staple. The tuft is wrapped around the staple in a U-shape, and then the s...

Benefits of technology

[0008] It has now been found that the foregoing and related objects may be readily attained in a bristle brush comprising a head having a multiplicity of closely spaced recesses in one surface thereof, and bristle tufts of U-shaped configuration disposed in the recesses and extending outwardly thereof. Each of the tufts is comprised of multiple bristles and has a bight portion disposed adjacent the bottom of the recesses and vertically extending leg portions. Staples are disposed between the leg portions of the tufts and press the bight p

Problems solved by technology

Generally, the staples have a relatively large surface area and thereby cost because of the amount of metal employed.
