TOOTH BRUSH Filed Nov. 4, 1964 WM WWW INVENTOR United States Patent ()fiice 3,258,805 Patented July 5, 1966 3,258,805 TOOTH BRUSH Michael Rossnan, 11724 Lovejoy Sh, Silver Spring, Md. Filed Nov. 4, 1964, Ser. No. 408,836 2 Claims. ((31. 15-110) The present invention relates to improvements in tooth brushes, one object being the provision of a tooth brush in which the bristles produce an erasing, instead of a grinding action in cleaning the teeth, and also in which the wear on the tips of the bristles in the present invention gives a visual indication or warning when the brush is ready to be discarded.
Another object of the invention is the provision of a wiper of a resilient type, which provides a polisher and also cleaner after the bristle part has been used.
In order that the invention may be fully understood and its advantages appreciated, attention is invited to the accompanying drawings, in which:
FIGURE 1 is a side view of a tooth brush embodying the present invention.
FIGURE 2 is a sectional view taken on the line 2-2 of FIGURE 1.
FIGURE 3 is an enlarged sectional view of one of the bristles, dotted lines showing when the bristles should be discarded.
Referring to the drawings, the numeral 1 designates the brush body, having a handle 2 and the operating elements 3.
Carried upon one side of elements 3 are synthetic bristles 4, generally of nylon, and each bristle is entirely coated at 5 with a vulcanized rubber, which acts as the cleaning and clearing elements of the brush. The bristles 4 are of a different color than the rubber coating, so that when the tip of the rubber coating is worn to exhibit or show the synthetic bristles, it warns the user that the brush should be discarded and a new one used.
Attached to the side 6 of the brush is a rubber pad 7, which acts as a final polisher and has a curved face 8 to conform to the shape of the respective jaws of the user, and so that the outer faces of the upper and lower teeth may be polished and any particles of tartar left by the bristle brushing may be removed.
From the foregoing description taken in connection with the drawings, it is evident that a very useful and practical tooth brush is here set forth, one that permits the teeth and between the teeth to be thoroughly cleared of tartar and food that may cling to the teeth, the bristles also acting as a warning to the user when the tooth brush should be discarded, and also by using the rubber coating on a relatively stiff bristle, no harsh 0r grating action to the enamel of the teeth results. Also with the soft rubber cleaning pad on the opposite side of the bristles, a complete tooth cleaning device results.
By using rubber encased bristles in this tooth brush, the gums are not scratched or torn, while they are softly massaged, which assists in preventing the receding of the gums, while also the teeth are thoroughly cleaned without scratching the enamel, as is the case when nylon or other stiff bristles are employed.
What is claimed is:
1. A tooth brush for tooth cleaning and gum massaging comprising a handle and an integral relatively flat terminal portion, said flat terminal portion being formed with a plurality of uniformly spaced recesses arranged in parallel rows, each recess having secured therein an elongated nylon bristle of uniform diameter extending from one face of the flat terminal portion, each bristle being entirely encased within a coating of rubber, said nylon bristles and said rubber coating each being formed of a dilferent color, whereby the user can visually determine when the tip of the rubber has worn down to expose the nylon bristles, thus preventing injury to the gums.
2. A tooth brush as defined in claim 1, including a rubber pad for polishing the teeth, said pad being attached to the opposite face of said terminal portion, the outer face of said pad having a longitudinally concave surface.
