Sept. 26, 1967 ,B. E. cox ETAL SHAVING BRUSH Filed April 12, 1965 United States Patent 3,343,201 SHAVING BRUSH Boyd E. Cox, 1931 NW. 81st Terrace, and Raymond Ponton, 9547 NW. 21st Ave., both of Miami, Fla.

Filed Apr. 12, 1965, Ser. No. 447,357 1 Claim. (Cl. 15-552) ABSTRACT OF THE DISCLOSURE A shaving brush removably attachable to a pressure- ,actuated lather dispensing container for use either inde- Our invention relates generally to shaving brushes and is directed particularly to a shaving brush for use in conjunction with pressure-actuated soap lather dispensing cans for supplying lather directly to the tip of the brush as needed in shaving.

Shaving brushes combined with dispensing means operative to apply soap or lather directly to the brush to simplify lathering and at the same time avoid wetting or soaping the hands, are known. Such combinations as have heretofore been devised, however, are of such unitary construction that the brush cannot be removed from the lather dispensing container for independent use, and are further deficient with respect to the complexity of their actuating mechanism for dispensing the lather to the brush.

It is accordingly the principal object of our invention to provide a shaving brush that will be removably attachable to a lather dispensing container for use either independently, as an ordinary shaving brush, or in conjunction with a pressurized dispensing can for automatically feeding lather directly to the tip of the brush as needed in shaving.

It is another object to provide a shaving brush of the character described for use with pressurized lather dispensing cans of the type having a dispensing nozzle perpendicularly disposed at one end of the can and yieldably attached at its base for universal rocking motion with respect thereto, and wherein dispensing i effected by displacing the nozzle from its perpendicular position relative to the container.

Yet another object is to provide a shaving brush of the above nature wherein the attaching means comprises an axial opening in the base of the shaving brush for receiving a dispensing can nozzle, whereby pressure exerted against the side of the brush when attached to the nozzle will rockingly displace it to dispense lather axially through the center of the brush.

Another object is to provide a shaving brush of the character described including selectively operable means for preventing displacement of the brush with respect to a lather dispensing can when attached thereto at its nozzle, thereby to prevent accidental actuation of the lather release mechanism while vigorously lathering the face with the brush and can combination.

Yet another object is to provide a shaving brush of the character described which will be simple in construction, inexpensive to manufacture, attractive in appearance and durable in use.

Other objects, features and advantages of the invention will be apparent from the following description when read with reference to the accompanying drawings. In the drawings, wherein like reference numerals denote corresponding parts throughout the several views:

FIG. 1 is an elevational view of a shaving brush embodying the invention;

FIG. 2 is an elevational view, partly in cross-section, illustrating the brush attached to a pressurized lather dispensing can for use in conjunction therewith;

FIG. 3 is a cross-sectional view similar to FIG. 2 but illustrating the brush in tipped or inclined relation with respect to the can to actuate the dispensing mechanism;

FIG. 4 is a fragmentary view, partly in cross-section, of a modified form of the brush embodying the invention including mechanism for selectively locking of the brush in perpendicular relation with respect to the can; and

FIG. 5 is a View similar to that of FIG. 4 but showing the locking mechanism in locking position with respect to the can to prevent the accidental dispensing of lather.

Referring now in detail to the drawings, 10 designates a shaving brush embodying the invention for use with a pressurized shaving lather dispensing can generally indicated at 11. The pressurized lather can 11 is of the type used by most manufacturers for packaging shaving soap to be dispensed in lather form, and comprises a cylindrical metal container member 12 having a convex upper end wall 13 from the center of which protrudes a dispensing nozzle 14. The dispensing nozzle, which is commonly molded of a synthetic plastic material, is tubular in form and provided with a central, outer, screw-threaded portion 15 adapted to receive a screw-on cap (not illustrated) seatable against the upper surface of the upper end wall 13 of the can to prevent accidental dispensing of lather during shipment and storage. The lower end of the nozzle 14 is formed with an annular flange portion 16 providing a seat for the lower end of a rubber grommet 17 fitted thereon. The grommet 17 extends through a central opening in the upper end wall 13 of the container member 12 and serves to seal off the outer wall of the dispensing nozzle 14 with respect to said container member. Side openings 18 are formed in the nozzle 14 in circumferentially spaced relation just above the flange portion 16, thereof, and the grommet 17 is formed with an annular recess 19 circumjacent said side openings. In ordinary use of the can in dispensing lather, the nozzle 14 is pushed sidewardly with the thumb, yielding under the resiliency of the rubber grommet 17, whereupon the fiange portion 16 of the nozzle will be tilted into a partially unseating position with respect to the grommet 17, as illustrated by the position thereof in FIG. 3, to allow the pressurized lather to escape into the annular recess 19 thereof and the side openings 18 of the nozzle 14, whence it will be discharged at the tip of the nozzle.

The brush 10 comprises a generally cylindrical base or handle portion 20 in the upper end of which bristles 21 are aflixed in any suitable manner, such as by embedding thereat in a waterproof cement. The base portion 20 of the brush is provided with an axial bore 22, a central portion of which is internally threaded as indicated at 23 to match the central screw thread 15 on a shaving lather dispensing can nOZZle 14. The lower end of the axial bore 22 in the brush base portion 20 is chamfered or divergently tapered, as indicated at 24. In use, the brush 10 will simply be screwed down upon the lather can nozzle 14 until the inner end of the chamfered portion 24 is in seating engagement against a beveled shoulder 25 provided on said nozzle, whereat the lower end of the brush base portion 20 will be supported in slightly spaced relation with .respect to the upper end wall 13 of the can, as illustrated in FIG. 2. As illustrated in FIG. 3, applying pressure against the side of the brush base portion 20 will cause the nozzle 14 to be rocked or tilted with respect to the top of the can, whereupon lather will be discharged through the nozzle as described above and flow through the center of the brush to the tip end of the bristles 21. It is ,to be noted that the can 10 can conveniently be gripped in the palm of the hand and the brush base readily pushed with the thumb to dispense lather as needed while lathering the face. There is thus no need to get lather on the hands preparatory to the use of a razor.

The embodiment of the invention illustrated in FIGS.-4 and ditfers from that of FIGS. 1, 2 and 3 described above only in the provision of a short cylindrical sleeve 26 surrounding the lower portion of the brush base 20a and movable between withdrawn (as illustrated in FIG. 4) and extended (as illustrated in FIG. 5) positions with respect to said base portion. When in withdrawn position the sleeve 26 has no effect on the operation of the device. When in extended position, the lower end of the sleeve 26 seats against the upper surface of the upper end wall 13 of the can to prevent accidental discharge of lather. Pins 27 (only one shown) extending outwardly of the brush base 20a at opposite sides thereof and through slots 28 (only one shown) having vertical portions 29 and upper sidewardly-extending portions 30 serve to constrain the sleeve 26 to movement between its above described upper and lower limits with respect to said base member. As illustrated in FIG. 5, the sleeve can be locked in place in its lower or projecting position by turning it with respect to thebrush base 20a so that the pins 27 extends through the sidewardly-extending portions 30 of the sleeve slots 28.

While we have illustrated and described herein only two forms in which the invention may conveniently be What We claim as new and desire to obtain by Letters Patent is:

A shaving brush for use with pressurized lather dispensing cans of the type having a dispensing nozzle perpendicularly disposed at one end of the can and yieldably attached at its base for universal rocking motion with respect thereto, and wherein dispensing is efiected by displacing the nozzle from its perpendicular position relative to the container, the combination comprising, a brush body member, brush bristles extending outwardly of one end of said body member, means for removably securing the other end of said body member upon the dispensing nozzle in spaced relation withrespect to the end of the can, said securing means including an end-to-end opening within said brush body member for passing lather from the nozzle to said brush bristles, said securing means comprising an internal thread within said end-toend opening threadable upon an externally-threaded portion on the nozzle, said end-to-end opening being formed with a divergently tapered portion extending into the other end of said base, means for preventing movement of said brush base with respect to the dispensing can when the brush is secured thereto, said movement preventing means comprising a sleeve surrounding said brush base and movable axially with respect thereto between positionsin and out of contact with the end of the can. and. means for locking said sleeve in contact position with respect to the end of the can.
