composed of a plurality of cylindrical clusters of bristles integrally molded with the body of the toothbrush and coated with a thin layer of dentifrice composition which is sprayed onto the bristles in an amount adequate for a single brushing only. Each cluster is composed of four bristles of approximately triangular section and is formed by bristles projecting from a cylindrical base of small depth which is bisected by a pair of rectangularly displaced diametral slots which define the inner surfaces of the bristles while the lateral surfaces of the latter are coincident with the periphery of the base.

INVENTOR CHAIM: fZaM BY ATTORNEY SINGLE-USE TOOTHBRUSII This invention relates to a single-use toothbrush formed of synthetic plastic material and more particularly to one formed with bristles molded integrally with the brush and coated with a dentifrice composition which is effective for a single brushing operation, and which is designed to be discarded thereafter.
It is the object of the present invention to mold a toothbrush composed of a handle at one end for convenient grasping, and a bristle portion at the opposite end wherefrom project a plurality of bristles which are capable of'clearising the teeth without undue irritation of the gums and which are spray-coated with a dentifrice composition so that a toilet item of low cost may be attained for a single use only.
The item of low cost may be dispensed from machines or distributed as a form of advertising in hotels, motels or other business establishments, or may be purchased economically for casual use by a traveller when the need therefor arises, and by all consumers that daily brush their teeth.
It is a further object of the invention to so correlate the physical characteristics of the molded plastic material, which may be a high density polyethylene, with the distribution of the individual bristle elements so that a light coating of the dentifrice composition, which is sprayed onto the bristles, is adequate for a single use only, so that after use, the brush is thrown away, thereby eliminating any possibility of infection. The bristles are formed in cylindrical clusters and are subdivided by four radial slots or by a pair of rectangularly displaced diametral slots, the dimensions of which, relative to the size of the clusters, provide adequate spaces between the bristles, so that the fluid dentifrice composition which is sprayed on the bristles in a light layer covers the resulting three faces of each bristle to provide a critically proportioned quantity of the composition, to make possible a single brushing of the teeth, following which the brush may be thrown away.
Other objects and purposes will appear from the detailed description of the invention following hereinafter, taken in conjunction with the accompanying drawings, wherein FIG. I is a top plan view of the toothbrush in accordance with the invention;
FIG. 2 is a front elevation of Fig. 1;
FIG. 3 is an enlarged bottom view of the bristle portion of the toothbrush;
FIG. 4 is a vertical sectional view along line 44 of Fi .3;
%*IG. 5 is a vertical sectional view along line 5-5 of Fig. 3, and
FIG. 6 is a vertical sectional view along line 6-6 of Fl .3.
lhe toothbrush T in accordance with the invention is formed of an integrally molded elongate handle portion 1 at one end thereof and a bristle portion 2 at the pposite end thereof. The cross-section of the handle portion is varied along the length thereof, as indicated in Figs. and 6, to afford a convenient hand-hold for the user of the brush, and the top of the bristle portion 2 is contoured to provide a comfortable base for the bristles as the brush is moved in the mouth.
The bristles 3 are molded integrally and project from the bottom face 4 of the portion 2. These bristles are arranged in cylindrical clusters which project from circular bases 5 of small depth at the junction of the bottom face 4 of brush 2 and the bristles. These circular bases are offset from each other with four individual bristles extending from each base. Each circular base may be approximately one-sixteenth to three thirtyseconds inch in diameter and the bristles are formed by bisecting the clusters with a pair of rectangularly displaced diametral slots 6 and 7 of approximately three sixty-fourths inch in width, or four radial slots of greater dimension so that in effect each cluster of bristles is constituted by four bristles of triangular section which taper to points at the end of the bristles remote from the bases 5. The slots 6 and 7 may be of uniform width, or they may flare or widen in radial directions from the center to narrow the bristles at their outer sides, as shown in FIG. 3.
The diametral slots 6 and 7 enable the sprayed dentifrice composition to be applied to the juxtaposed faces of the bristles in each cluster, as well as to the outer curved faces of the latter.
The bristles project from the base of the brush for approximately three-eighths inch in order to permit a limited flexing thereof so that the teeth may be brushed without undue irritation of the gums.
An adequate brush area may be attained by the provision of approximately ten clusters which extend along the length of the bristle portion along each edge thereof spaced from each other approximately oneeighth inch apart, with one or more rows of bristle clusters between the outer rows. The adjacent rows of clusters are displaced longitudinally from each other to give rise to a staggered effect which provides an effec tive brushing area. The lateral spacing between the longitudinal rows may also be one-eighth inch apart, or slightly less.
Following the molding of the brush, the bristles are sprayed with a dentifrice composition having a suitable amount of detergent and abrasive ingredients in conjunction with wetting and flavoring agents.
The following formula has proven to be especially effective:
carboxymethylcellulose (I20) 0.9 gm. saccharin sodium 0.18 gm. methyl paraben sodium lauryl sulfate 2.5 gm. dicalcium phosphate 7 54.0 m. strontium chloride 5.0 gm. glycerin L0 gm. propylene glycol 18.0 gm. water l3.5 gm. mineral oil 1.0 cu. mm. peppermint oil 0.7 cu. mm. oil of pine cu. Iran.
The dentifrice composition may be prepared and applied to the bristles in following manner:
Dissolve the methyl paraben in the propylene glycol; wet the carboxymethylcellulose with the glycerin and then the propylene glycol solution. to make a slurry; dissolve the saccharin sodium, sodium fluoride and strontium chloride in the water; add the aqueous solution to the carboxymethylcellulose slurry slowly while stirring (in a l-Iobart" mixer), continuing stirring until a homogeneous gel results (heat may be used); add the dicalcium phosphate slowly to the gel while stirring until homogeneous; add the mineral oil, peppermint and pine oils and the sodium lauryl sufate and mix until evenly dispersed; (the paste may be milled and deaerated if necessary); add warm water of approximately 50C. slowly, with constant stirring to a paste consistency until it becomes sufficiently fluid for spraying; introduce the warm mixture into a spray dispenser using a Freon propellant; spray on bristles of the brush and place the brush in a warm place of 30 to 40C. to dry.
The spraying of the dentifrice composition onto the bristles results in a highly improved product over the practice of dipping the bristles into the composition, even in the case of molded plastic bristles.
I claim:
1. A single-use toothbrush of generally elongate shape, comprising a. an integrally molded handle portion of synthetic plastic material with a bristle portion of generally rectangular outline at one end thereof,
b. a plurality of cylindrical clusters of bristles, of a length of approximately three-eights inch, projecting from a face of said brush at said bristle portion to form said generally rectangular outline,
c. a cylindrical base of small depth at said face constituting the root of each cylindrical cluster of bristles having a pair of rectangularly displaced diametral slots extending from said base to divide each cluster into four bristles of triangular crosssection, with each bristle tapering to a point at the free end thereof remote from said base,
(1. each of said cylindrical clusters of bristles being of a diameter ranging from one-sixteenth to three thirty-seconds inches, with the width of the diametral slots being approximately three sixtyfourths inches,

f. a coating of dentifrice material dispersed uniformly on all faces of said bristles in consequence of the spacing of said bn'stles from each other and from the bristles in the adjacent clusters to a degree sufficient to have the composition sprayed onto all surfaces of said bristles.
