United States Patent O 2,698,452 CREAM DISPENSING BRUSH Adolph L. Osrow, Jamaica, N. Y. Application November 9, 1950, Serial No. 194,831 1 Claim. (Cl. 15-136) This invention relates to a sanitary shaving brush capable of dispensing shaving or similar cream as required for use.

lt is the object of this invention to provide a shaving brush having a shaving cream reservoir associated therewith which is capable of injecting shaving cream into the interior of the brush as required.

Itis a further object of this invention to provide a shaving brush of the type indicated which may be easily maintained in a sanitary condition wherein the amount of shaving cream injected into the brush may be readily controlled and any excessive amounts of shaving cream may be retracted into the interior of the reservoir.

Another object of this invention is to provide a shaving brush of the character indicated wherein the reservoir may be refilled as desired from such a conventional source as a collapsible tube or from a suitable material storage device.

A further object of this invention is to provide a shaving brush of the type indicated wherein the reservoir serves as a convenient and eicient handle for the entire device.

It is an additional object of this invention to provide a simple and eicient device of the type indicated which may be readily and economically manufactured on a large scale and which is simple to use, and without mechanical elements which may get out of order.

Other and further objects of the invention will be indicated or will otherwise become apparent from the drawings, specications and claim appended hereto or will otherwise be made obvious.

In the accompanying drawings:

Figure l is an elevational view of the device;

Figure 2 is a longitudinal cross-section of the device shown in Figure l, and

Figure 3 is a longitudinal section of the reservoir portion of the device showing a collapsible tube in position for refilling the reservoir, in broken lines.

As shown in Figures l and 2 the device comprises a shaving head which carries bristles 11 suitable for forming a lather upon the face. A body or head 10 is formed of two compartments divided by an intermediate wall 23. One of said compartments forms a bristle receiving recess 12 into which the butt ends of the bristles are secured in a suitable manner such as by compacting the ends of the bristles in a suitable cement. In securing bristles 11 within recess 12, said bristles are so disposed as to provide a cavity 18 at substantially the axial center of the brush. The other compartment of said body or head 10 comprises an annular recess 13 which is provided with internal threads 14 adapted to removably engage with the external threads 16 formed on the neck 19 of container 15. Intermediate wall 23 is provided with a centrally disposed perforation 17 which registers with the central space or cavity 18 formed with the butt ends of bristles 11.

Handle or container comprises the reservoir wherein which the shaving material such as a suitable shaving cream is stored for discharge among the brush bristles. Container or reservoir 15 is formed of a flexible and resilient material preferably a polyethylene plastic, it being understood that rubber or similar suitable materials may be utilized for this purpose.

The handle or container 15 is provided with a restricted end or neck portion 19 which comprises the sole opening giving access thereto. A bushing 20 formed of a rigid metallic or plastic material is inserted into the interior of neck 19. Bushing 20 is provided with a circumferential flange 2l and is internally threaded so as to removably receive the neck of a conventional type collapsible tube in which such creams are customarily sold.

As shown n Figure 3, container 15 is filled and refilled by engaging the screw threads of a collapsible tube 22 of shaving cream with the internal threads of bushing 20 and injecting the contents of the collapsible tube into res- ICC ervoir or container 15. The collapsible tube may be of conventional type. When the reservoir or container has been filled the collapsible tube is disengaged therefrom and the reservoir is mounted on the brush head by engagement with the internal threads in the annular recess 13. Bushing 20 serves to maintain the neck portion 19 of the reservoir in a more rigid condition and in cooperation with flange 21 thereon permits a liquid and airtight seal to be formed between the reservoir and head 10.

When it is desired to inject lather forming shaving cream into the interior of the brush it is merely necessary to deform the container by pressing upon or compressing the side walls; the amount of cream injected being determined by the degree to which the reservoir is deformed. The manner of deformation is illustrated by the broken lines in Figure 2. If an excessive amount of shaving material is unintentionally introduced into the interior of the brush it is merely necessary to suddenly release the reservoir from deformation thereupon the vacuum formed in the reservoir tends to suck back a substantial portion of the cream back into itself from the bristles of the brush.

In this manner the amount of shaving cream dispensed is readily controlled and the amount available for use at the brush bristles may be reduced if desired. This element of control in addition to regulating the amount of lather produced by the brush permits it to be maintained in a sanitary condition with an economy in the use of the cream since the amount of shaving cream pressed in the brush may be reduced as desired. The brush may be readily removed, washed, dried and otherwise sanitarily maintained. It may also be readily refilled when empty from the commercially available shaving cream tubes. It has been found advantageous to use a reservoir formed of a polyethylene plastic material since such material is exible and resilient yet is sufficiently rigid to act as a handle for the brush. Other materials having similar suitable characteristics may also be utilized. The entire brush may be used in the conventional manner and it is unnecessary to shift the hand from its normal grasp of the container which comprises the brush handle in order to dispense the cream. As the lather is being applied an additional supply of cream may be added to the brush by merely clenching the hand more firmly over the reservoir which comprises the handle for the brush.

I have here shown and described a preferred embodiment of my invention. It will be apparent, however, that this invention is not limited to this embodiment and that many changes, additions and modifications can be made in connection therewith without departing from the spirit and scope of the invention as herein disclosed and hereinafter claimed.

I claim:

A dispensing brush adapted to be filled from a material storage source comprising a body portion and a container portion, bristles secured to said body portion, said container comprising a hollow handle formed of a resiliently deformable material adapted to contain the material to be dispensed, said container portion being provided with an externally threaded open end, a rigid bushing positioned within said open end circumferentially reinforcing said open end against transverse radially inward deformation, said bushing including a transversely extending flange having an inner surface sealingly abutting the open end surface of said container and including an outer transverse surface, said body portion comprising an internally threaded annular recess adapted to be threaded on said threaded open end, one end of said recess comprising a transverse perforated wall whereby said flange is forced into sealing contact with both the body portion and the said open end when the body and container portions are threadedly connected.
