Description
BACKGROUND OF THE INVENTION
[0001] The present invention is directed toward a shaving brush
that includes a chamber in the handle including a mechanical or
electrical stirrer or mixer for converting a liquid into shaving
foam to be dispensed onto the brush bristles.
[0002] Shaving cream or foam or lather is normally applied to a
man's face before shaving in order to maintain moisture on the skin
and whiskers. Keeping them moist results in a closer shave with
less irritation to the skin. For many years, before the advent of
canned shaving cream, men applied shaving foam to their faces with
a shaving brush.
[0003] The greatest benefit from shave brush use is the tendency to
soften and lift facial hair before a shave. Applying shaving cream
by hand mats hair or raises it unevenly. Shave brush use, however,
requires agitation of the soap or cream in a mug to form a lather
suitable for shaving, before application of the lather to the face.
Therefore, a razor does not need to be pressed to the skin in order
to provide a close shave.
[0004] Conventionally, a wet brush was dabbed onto a solid soap
block which was usually kept in a mug. This could become somewhat
messy and unsanitary. While the brush could be rinsed and cleaned
after each use, germs could grow on the wet soap block in the mug.
Furthermore, the use of a brush and mug could be inconvenient when
traveling as they both had to be carried along.
[0005] Over the years, numerous attempts to solve this
inconvenience have been proposed. One proposal has been to make the
handle of the brush hollow to provide a chamber for holding a
quantity of shaving lather therein. One or more passageways between
the chamber and the brush bristles allowed the lather to be forced
from the chamber onto the bristles. See, for example, U.S. Pat. No.
1,170,923 to Malkin and U.S. Pat. No. 1,412,958 to Pearlmutter. The
entire contents of those patents are incorporated herein by
reference.
[0006] These prior inventions, however, still suffered from
significant deficiencies. The chambers in the handles could hold
only a small quantity of foam. Accordingly, they had to be refilled
often which meant that a quantity of foam or lather had to be
carried when traveling or other means had to be provided for
creating the lather in order to refill the chamber.
[0007] For example, a lather generator such as suggested by U.S.
Pat. No. 3,220,954 to Malbe could be carried along with the shaving
brush for refilling the hollow brush chamber. Malbe describes a
device wherein water and soap flakes are poured into a closed mug
and the combination is agitated by a motor-operated spinning blade
to create the foam or lather. The entire contents of the Malbe
patent is also incorporated herein by reference. Again, however,
both the brush and the lather generator had to be carried
together.
[0008] There is, therefore, a need for a shaving brush that is
self-contained and is capable of creating its own shaving lather or
foam.
SUMMARY OF THE INVENTION
[0009] The present invention is designed to overcome the
deficiencies of the prior art discussed above. It is an object of
the present invention to provide a shaving brush with a hollow
handle that can be used by itself to create shaving foam or
lather.
[0010] It is a further object of the invention to provide a shaving
brush that is capable of converting liquid soap into shaving lather
simply and easily with the push of a button.
[0011] In accordance with the illustrative embodiment demonstrating
features and advantages of the present invention, there is provided
a shaving brush for applying shaving foam or lather to a person's
body, The brush includes a brush head comprised of a plurality of
bristles secured at one end to a base and a hollow handle secured
to the opposite side of the base. The handle can contain a foamable
liquid therein. A passageway extends between the interior of the
handle and the bristles through the base. A small electric motor on
the outside of the handle spins an agitating blade within the
handle to turn the liquid into foam which is forced through the
passageway when a portion of the handle is depressed. The handle
also includes an opening therein which allows liquid to be
introduced into the interior of the hollow handle to be turned into
foam by the spinning blade.
[0012] Other objects, features, and advantages of the invention
will be readily apparent from the following detailed description of
the preferred embodiment thereof taken in conjunction with the
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] For the purpose of illustrating the invention, there is
shown in the accompanying drawings one form which is presently
preferred; it being understood that the invention is not intended
to be limited to the precise arrangements and instrumentalities
shown.
[0014] FIG. 1 is an overall perspective view of the shaving brush
of the invention;
[0015] FIG. 2 is a vertical cross-sectional view thereof, and
[0016] FIG. 3 is a perspective view similar to FIG. 1 but with
portions broken away to illustrate the interior features of the
brush handle.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] Referring now to the drawings in detail wherein like
reference numerals have been used throughout the various figures to
designate like elements, there is shown in FIGS. 1-3 a shaving
brush and mixer or agitator constructed in accordance with the
principles of the present invention and designated generally as 10.
The brush 10 is comprised of a brush head 12 which includes a
plurality of bristles 14 that are secured at their upper end 16 to
a base 18. A hollow handle 20 is secured to the base 18 on the
opposite side of the bristles. The hollow handle is in the form of
a chamber that is adapted to contain a quantity of a foamable
liquid 22 therein.
[0018] A plurality of small openings or passageways 24 in the base
18 provide communications between the hollow handle 20 and the
bristles 14. An agitator 26 in the form of a rotatable blade is
located in the interior of the handle 20 and is capable of mixing
or agitating the foamable soapy liquid 22 in order to turn the
liquid into shaving lather or foam 28.
[0019] An electric motor 30 positioned at the top of the handle 20
is connected to the agitator 26 through the drive shaft 32. The
motor 30 includes a small battery (not shown) and the push button
switch 34 located on top of the motor 30 turns the motor 30 on and
off as desired to rotate the agitator 26.
[0020] The agitating system comprised of the motor 30, blade 26,
shaft 32 and button 34 can be constructed similar to the system
shown in the Malbe patent discussed above. However, it will be of a
substantially smaller size so as to fit into the handle 22 of the
brush 10. This is, of course, by way of example as other types of
blades and other types of motor means are also possible. By way of
example, a wind-up spring motor or other types of mechanical
devices that are activated by a person's finger or hand could also
be utilized in lieu of an electric motor.
[0021] In order to force the foam 28 from the interior of the
handle 20 through the passages 24 to the bristles 14, at least a
portion of the handle 20 is formed of a resilient or rubbery
material such as shown at 36. Alternatively, and as shown in the
Malkin and Pearlmutter patents discussed above, the entire handle
20 could be made of a resilient material. In any case, when the
resilient portion 36 of the handle is depressed, air pressure
forces the foam 28 downwardly through the openings or passages 24.
A small one-way valve 38 in the resilient material portion 36
allows air to enter so as to permit the resilient material to back
outwardly and be restored to its original position after it is
depressed.
[0022] The openings or passages 24 are preferably small enough so
that no liquid or foam can pass therethrough without pressure
forcing the same through the openings. Alternatively, simple
one-way flapper valves or the like could be included. In lieu of
the plurality of small passages 24 it is not beyond the scope of
the present invention to include a single passageway such as shown
in the Malkin and Pearlmutter patents.
[0023] In order to introduce the foamable liquid material 22 into
the interior of the handle 20, an opening or port 40 is formed
adjacent the top thereof. A plug 42 is used to close the port 40
after liquid is introduced into the handle. The plug 42 can either
be threaded into the fill port 40 or it can be made of a rubbery or
elastomeric material and be friction fit into the same.
[0024] The present invention may be embodied in other specific
forms without departing from the spirit or essential attributes
thereof and accordingly, reference should be made to the appended
claims rather than to the foregoing specification as indicating the
scope of the invention.
