Abstract

An end brush for use in a dental unit or the like includes a base formed of solified fiber material. The base includes an outwardly projecting portion, which is adapted to be received within a mounting structure provided on the dental unit. An apparatus and method for forming the end brush are disclosed.

Claims

1. An end brush comprising:

a plurality of generally parallel fibers bundle to form a brush having first and second ends; and

, a base formed at said first bundle end by solidifying said fibers, said fibers extending away from said base and terminating in said second end, the base having a first portion disposed in a plane substantially perpendicular to the fibers and a projecting portion extending from said first position in a direction opposite to said fibers, said projecting portion being of smaller diameter than said first portion, and having means for connecting the base to a means for rotating the brush, the projecting portion having a protrusion extending perpendicular to the projecting portion, for connecting the base to a means for rotating the brush, the protrusion spaced away from and substantially parallel to the first portion of the base.

2. The end brush of claim 1 wherein the projecting portion is substantiality cylindrical, the projecting portion having a side wall and an end wall formed of solidified fiber material, the fibers extending upwardly from the end wall of said projecting portion and being partially contained within the side wall of the substantially cylindrical projection.

3. An end brush comprising:

a plurality of generally parallel fibers bundle to form a brush having first and second ends; and

, a base formed of solidified fiber material, said fibers at said first bundle end by solidifying said fibers extending away from said base and terminating in said second end, the base having a first portion disposed in a plane substantially perpendicular to the fibers and a projecting portion extending from said portion in a direction opposite to said fibers, said projecting portion being of smaller diameter than said first portion, and having means for connecting the base to a means for rotating the brush, the connecting means being a rib extending outwardly from the projecting portion, between the projecting portion and a lower surface of the first portion.

4. The end brush of claim 3 wherein the projecting portion is substantially cylindrical, the projection portion having a side wall and an end wall formed of solidified fiber material, the fibers extending upwardly from the end wall of said projecting portion and being partially contained within the side wall of the substantially cylindrical projection.
