cnsunn 'roo'rmsnusn' Application med larch 1,

The object of my invention is to produce a combination tooth brush provided with means for insert' a quantity of tooth paste therein, to be fed irectly into the brush sec- 13 tion at the time of using.

Another object is to produce an inexpensive tooth brush, suitable for dispensing in public wash rooms, or other public places wherc the article is generally used, and immediately dis- 19 carded after using.

A further object is to produce a -sanitary combination'tooth brush with paste inserted therein at the time of manufacturing the brush, but then sealed and remaining sealed until applied by the user.

- A still further object is to design an inexpensive sanitary tooth brush, containing samples of tooth paste for advertising purposes, and suitable for dispensing to the public through vending machines at a very low cost.

These several objects are attained in the preferred form by the construction and ar-' .rangement of parts more fully hereinafter set forth.

Similar parts on all drawings are marked by similar numerals or letters.

brush being slotted along the bottom of the recess for allowing the paste from the inclosed capsule to be forced therethrough and into the brush bristles.

I will now describe more fully the detailed construction of my device, referring to the drawings and the marks thereon.

The handle 1- is preferably made of wood, wood pulp or papier-mach, although it may be made of celluloid, or any other suitable material desired, and is formed with an approximately straight bar handle section, with rounded edges, and having an enlarged brush head section 2- formed on one end thereof. The'head section 2 is preferably made approximately a'rectangular exterior design as shown in the Figs. 3 and 6 of the drawings, and is provided with two rows of ordinary brush bristles 3 symmetrically placed along one side thereo The bristles -3 being mounted therein in the ordinary manner used for makin brushes of this type. Along the opposite si e of the brush head -2 is formed a longitudinal T-shaped recess 4 extending nearly the entire length of the head section, said recess being 0 en along the brush head back and end. he recess 4 is provided with overhanging slide edges '5- along the side wall 0 ening. A narrow paste slot 6 is formed t rough the brush head body 2- positioned centrally along the recess bottom and o ens within the brush bristles 3. between t e two rows as mounted on the op osite side of the head. The slot 6, may 1% desired be extended to the head end, although it will somewhat weaken the handle, and also allow a slight spreading of the paste outside the brush. The inner edges a, of the slot 6 are preferably curved as is indicated in the Fig. 6 of the drawings. Within the recess 4- is inserted a small capsule 7, formed of an exterior desi within t e grooved recess opening. The capsule 7 is preferably made of pliable material such as soft lead, pewter, or soft materials commonly used for tooth paste tubes &c., although other materials such as capsule gelatin, wax paper or glassine may be used if desired. The capsule 7 is preferably formed with two sheets of material -band 0, both of the same dimensions and approximately that of the bottom of the brush head recess 4, The sheet b is of a stronger material than the sheet c, the sheet cbeing sufliciently weak that it will tear along the paste slot 6- when the capsule is placed within the recess 4- an pressure is applied thereon. The sheets band 0 being placed together flatwise,-one over the other and with their edges coincidin' are sealed along their edges oy a folded edge bar -d securely clamped thereon as indicated in Fig. 13 of the drawings. The sheets b-- and 0- may be sealed together along their edges in any other manner that will provide a secure edge joint. Within the capsule 7, between the wall sheets -band c is forced a small quantity of tooth aste 8- and which is inserted therein be ore the final sealing of the capsule edges. The capsule 7- is then inserted within the brush head recess --4,

through the end recess opening, and with the thin capsule sheet c placed on the recess bottom, over the paste slot 6-, the folded edge bars da 01615 the sides of the capsule engaging the slide ges 5- for retaimng the capsule fixedly within the brush head recess. When the paste capsule is fully insertto be fitted and retained fixedlyed therein, then by applying pressure on the capsule wall exposed through the side wall opemng, the thin-ca sule sheet 0'- will tear a ong the edges 0 the slot 6-, and the tooth paste 8- be forced through the slot and mto the brush mounted on the opposite side of the handle.

The ca sule may, if desired, be made of a single tu ular section 7a---, and all of the same material, by slightly flattening and creaslng the tube as a ong the edges --e for engaging the brush head slides -5, and as indicated in Figs.,14 and 15 of the drawings, and provided with folded ed e bars at both ends. The capsule si e wall bemg partially perforated along a centerline -gas indicated in Fig. 14, and so as to weaken thewall directly over the slot -6 and allowing same to tear at that point when inserted within the brush head recess 4- and pressure applied thereon as heretofore described. The capsule being previously filled with paste before sealing as in the former case, and is used in the same manner as heretofore described. In either case, the capsule may be made of a size for retaining sufiicient tooth paste for several applications, or contain only sufiicient quantity of the paste for on'ceusing, the latter bein preferred for the inexpensive type of rush where made of papier-mach, to be used only once and discarded. For better grades of brushes which may be retained for successive use a larger capsule is more serviceable.

When desired, the capsule may be filled with a medicated paste prepared for tooth and gum treatment, and the brush used as a medical appliance also.

A modification of my brush is illustrated in Figs. 7 8, 9 and 10 of the drawings, the handle and brush head-2awith back recess 4a;- bein the same as heretofore de scribed, while t e paste slot .6a is enlarged along one side thereof by anadded knife slot 10, and which is extended only partially through the brush head wall, the ends of the slot -10 being projected slightly beyond the ends of the paste slot -6a. Within the knife slot -10 is placed a sharp knife blade 11, either with a" smooth edge as shown in Fig. 9 of the drawings, or a blade formed with a sharp toothed edge as illustrated in Fig. 10. The shar edge of the blade 11 being projecte slightly. above the bottom of the back recess 4a,-, and sufiicient for slittin the bottom capsule wall when inserted within the recess. For this type of head, the capsule 7 may be made of uniform material throughout, and inserted within the brush recess either side up, said apsule bein inserted therein only at the time of using, w e in the former types of brush head, the capsule may be laced within the brush head recess at the tune of its manufacture.
