Abstract
An improved bristle for toothbrushes having a spiral groove along the longitudinal shaft of the bristle to increase the abrasiveness and expand the surface area of the bristle used in cleaning, the grooved bristle is combined into tufts and mounted on a suitable platform so that when the surface to be cleaned is scrubbed with a toothbrush having the improved bristle of the invention the bristles twist and bend and in the process the shaft of the bristle scrapes on the surface to be cleaned and agitates the fluid in and around the area to be cleaned thereby increasing the cleaning ability of the brush.
Claims8
A bristle consisting of a base end, and a tip end connected to each other by means of a substantially rigid shaft portion wherein said substantially rigid shaft of said bristle has at least one shallow spiral groove along its longitudinal axis and wherein said substantially rigid shaft is sufficiently flexible so that said bristle will twist, bend and rotate on its axis when said base end of said bristle is held in a fixed position on a brush device and vertical and horizontal pressures applied to the tip of said bristle in a brushing motion such that the twisting, bending and rotating of said bristle upon the application of vertical and horizontal pressure on the tip of said bristle causes the tip of said bristle and said substantially rigid shaft of said bristle to become an abrasive device with respect to the surfaces to be cleaned and wherein said twisting, bending and rotating of said bristle increases with the application of increased pressure on the tip of said bristle.
The bristle claimed in claim 10 wherein said bristle made of a plastic material and wherein said bristle is of such flexibility as to be capable of bending and rotating on an axis of thirty to ninety degrees when used in scrubbing or cleaning.
A brush device for use in cleaning and scrubbing including a bristle receiving body portion having a plurality of substantially rigid bristles disposed therein and wherein said body portion of said device has a plurality of holes adapted for receiving said bristles and wherein said bristles are arranged in tufts of bristles and wherein each of said bristles has at least one spiral groove along the longitudinal axis of said substantially rigid shaft of said bristle wherein the scrubbing action of said brush device causes said bristle to bend and twist about its axis and to agitate liquid substances which are present in the area to be cleaned and wherein the tips of said bristles and said substantially rigid shaft of said bristles act as cleaning surfaces and whereby said longitudinal axis having said spiral groove acts as an extended scraping device with respect to the surface to be cleaned.
A toothbrush having a head portion and a handle portion wherein said head portion has a plurality of holes adapted for receiving tufts of bristles in each hole and wherein each tuft consists of not less than ten bristles each of said bristles having at least one spiral groove along the longitudinal axis of said bristle and wherein upon the application of pressure to the tips of said bristles and use of a scrubbing action thereon said bristle bends and rotates and agitates saliva in the mouth and wherein said tips and said longitudinal axis of said bristles act as cleaning surfaces with respect to the teeth and gums and whereby said longitudinal axis having said spiral grooves acts as an extended scraping device for the removal of waste materials, including plaque, from the teeth and gums.
