Abstract

An oral brush with a handle having a longitudinal axis and a head mounted on the handle, the head including an elongated hub extending generally axially from the handle and bristles mounted in the hub, including bristles along most of the length of the hub which extend radially in all directions from the hub and which taper down in length from the base end of the hub to the front tip of the hub, and including bristles extending from the front tip of the hub in all directions as generally semispherical radii, the free ends of the bristles of the head defining a conical or bullet-shaped envelope.

1 . An oral brush with a handle having a longitudinal axis and a head mounted on the handle, said head comprising an elongated hub extending generally axially from the handle and bristles mounted in the hub, including bristles along most of the length of the hub which extend radially in all directions from the hub and which taper down in length from the base end of the hub to the front tip of the hub, and including bristles extending from the front tip of the hub in all directions as generally semispherical radii, the free ends of the bristles of said head defining a conical or bullet-shaped envelope.
