United States PatentO 3,408,151 SELF-LATHERING SHAVING BRUSH John Cleghorn, 18947 Milmore Ave., Gardena, Calif. 90247 Filed Oct. 6, 1965, Ser. No. 493,492 2 Claims. (Cl. 401-291) I ABSTRACT OF THE DISCLOSURE This invention relates to a shaving brush apparatus which provides for a means of conducting soap from pressurized containers directly into the bristles of the shaving brush.

This invention relates to shaving brushes and more particularly self-lathering shaving brushes.

With the advent of the pressurized shaving soap dispenser it was found that the best method of using the aerated soap dispensed therefrom was to first discharge the same into the users'hand and thereafter apply it to the area to be shaved. The soap thus applied is then lathered by a shaving brush. This, however, is untidy and inconvenient in that the users hand is covered with soap and a separate soap container (the dispenser) is necessary. This is particularly inconvenient when travelling because of a problem of limited packing space.

In the invention in the instant application, these problems are eliminated by encompassing the soap dispensing container in the handle of the shaving brush. The soap is discharged into the base of the brush bristles thereby evenly distributing itself throughout the bristles. Thus, the aerated soap from the container need not be first dispensed into the users hand, but is applied directly to the area to be shaved by the shaving brush. This integrally self-contained unit is particularly useful when travelling and packing space is limited.

Further, in the event a container separate from the brush is desired or necessary, this invention can readily be adapted to function in substantially the same manner even though utilizing the extraneous soap supply.

Accordingly, an object of this invention is to provide an integral self-lathering shaving brush.

Another object is to provide a self-lathering shaving brush capable of functioning with an extraneous soap supply source.

Other objects and advantages of the invention herein will become obvious from the following description taken in conjunction with the accompanying drawings in which:

FIG. 5 is a side sectional view of the adapter shown in FIG. 4 which permits the self-lathering shaving brush of FIGS. 1-3 to be utilized with an extraneous soap supply source;

FIG. 6 is a top plan view of the adapter shown in FIG. 5;

FIG. 7 is a side sectional view of another embodiment of the self-lathering shaving brush of FIGS. 1-6; and

Patented Oct. 29, 1968 ice FIG. 8 is a sectional view of the brush of FIG. '7 taken on the line 88.

Referring more particularly to FIGS. 1-3, the number 10 designates generally the body of the self-lathering brush described herein which is 'provided'with ordinary bristles 11 as found in most lathering brushes and a hollow internal cavity 12. Bristles 11 are secured to body 10 by any adhesive material, or the like, to a base 13. Base 13 is in turn secured to the body 10 of the brush by adhesive means 14 and is provided with a longitudinal channel 15 therethrough. Longitudinal channel 15 interconnects the base of bristles 11 and cavity 12 contained in body 10 and has an expanded portion 15a. Cavity 12 is enclosed by body base 16 which is threadedly engaged to one end of body 10 at 17. A portion of-the internal surface of body base 6 is provided with-a thickened convex section 18. Although convex section 18 is shown here secured to body base 16 at a fulcrum point 19 any suitable means which provides flexing thereof may be utilized.

A container 20 containing a lathering compound currently commercially produced which is packaged under pressure, is provided with an atomizing dispensing nozzle 21 and is accommodated in cavity 12 with the atomizing nozzle 21 loosely positioned in expanded channel portion 15a. Upon the application of an axial force to convex section 18, said section concomitantly contacts lower end 22 of container 20 thereby displacing said container upwardly within cavity 12 so that the upper end 23 thereof abuts against internal annular shoulder 24 provided 'by body 10.

It should be noted that since the longitudinal dimension of expanded channel portion 15a of axial channel 15 is less than the axial displacement of container 20, when dispensing nozzle 21 engages walls 25 of expanded portion 15a, the axial displacement of said dispensing nozzle is restricted. Thus, as container 20 is being axially displaced, the longitudinal movement of dispensing nozzle 21 in the direction of the displacement of the container is terminated by Walls 25 of expanded portion 15a. Consequently, as the longitudinal displacement of container 20 continues until it engages internal annular shoulder 24, dispensing nozzle 21 is simultaneously depressed into said container thereby discharging the contents thereof through longitudinal channel 15 into the bristles 11 of the brush. That is, since the distance between the maximum height of the expanded channel portion 15a and the internal abutment shoulder 24 is less than the distance from the point of engagement of the abutment shoulder with the body of dispenser 20 and the point of engagement of the dispenser nozzle 21 with the expanded channel portion 15a, the upward displacement of the nozzle 21 is restricted before that of the container 20 so that the nozzle 21 is depressed into the body of said container thereby discharging the contents thereof.

Upon the removal of the axial pressure against convex section 18, said section, and concomitantly container 20, are displaced in the opposite direction (downwardly) so that the container is disengaged from its abutment position against internal annular shoulder 24. As container 20 returns to its original position (i.e., prior to displacement), dispensing nozzle 21 is also disengaged from Walls 25 of the expanded channel portion 15a thus permitting said nozzle to emerge from the body of container 20 thereby terminating the dispensing process. The brush is then used in the normal fashion to spread the lather which is now contained in bristles 11 thereof over the surface to be shaved.

In the event it is notdesired to provide a container of lathering soap compound within the body of the brush, an adapter 26 may be attached to body 10 at 17 rather than a body base 16 (see FIGS. 4-6). Adapter 26 is provided with a-longitudinal hollow'conducting duct 27 which is snugly positioned in expanded portion a provided by longitudinal channel 15 so as to be in alignment therewith. The base of hollow duct 27 is provided with an expanded portion 27a which is adapted to accommodate a dispensing nozzle of a soap container as did expanded portion 15a provided by longitudinal channel 15.

. In use, expanded portion 27a is fitted over the dispensing nozzleof-a container (not shown) containing a lathering compound thereby displacing the nozzle into the container so as to dispense the contents thereof. The lather thus discharged from the nozzle is conducted through hollow duct 27 and hollow channel 15 in longitudinal alignment therewith into the bristles 11. The brush is then used similarly to the brush described in FIGS. 1-3.

FIGS. 7-8 disclose another embodiment of the invention wherein body 29 is provided with an integral body base 30. Body 29 is also provided with a hollow duct 31 which is secured to base 32. Channel 33 is aligned with longitudinal channel 34 passing through base 32. Channel 33 of hollow duct 31 is also provided with an expanded portion 33a at one end thereof. All the other elements present in the brush disclosed in FIGS. 7 and 8 are similar in structure to those described in FIGS. 1-6. The lathering brush in FIGS. 7 and 8 is used in the same manner as is the brush described in FIGS. 4-6.

In the foregoing I have described an integral selflathering shaving brush which is convenient and not untidy to use and which is capable of functioning with currently existing pressurized soap dispenser.

While several embodiments of the invention have been described, it is, of course, understood that the particular embodiments of the invention herein discussed are for illustrative purposes only and that various changes may 4. be made therein without departing from-theprinciples of the invention or the scope of the annexed claims.

I claim:
