COMBINATION SHAVING BRUSH AND STAND
Abstract
A shaving brush and stand with the brush having a central
shaving cream passageway occupied by a stem portion of the stand
when the brush is stored in place thereon. Removal of the brush
from the stand leaves the passageway open for the subsequent flow
of aerated shaving cream. The lower end of the shaving brush is
shaped for momentary sliding connection with a standard pressurized
aerosol shave cream container to impart a charge of shaving cream
to the brush bristles.

Claims
What I desire to secure under a Letters Patent is:
1. A combination shaving brush and stand with the brush adapted for
axial engagement with a pressurized shaving cream container having
concentric annular walls and a valve stem at its upper end for the
discharge of shaving cream, said valve stem discharging the shaving
cream upon depressed engagement with the brush, said brush and
stand comprising,
a stand for the shaving brush comprising a base and elongate
upright stem portion additionally serving to clean said brush,
a shaving brush body having bristles secured within its upper end
and having a centrally disposed passageway therethrough for
directing shaving cream to the bristles and alternatively for the
reception of the stand stem, said brush body having an annular wall
of reduced diameter depending from its lower end with inner and
outer concentric vertical wall surfaces for axial sliding
engagement with the annular wall surfaces of the pressurized
container, a shoulder formed within said brush body in
communication with said passageway and contactable with the upper
end of the valve stem upon closing axial movement of the brush body
and container for biasing the stem downwardly for release of the
shaving cream, said concentric vertical wall surfaces of the
annular wall being concentric with the passageway and serving to
assure axial alignment of said shoulder and the central passageway
of the brush body with the valve stem of the container.
Description
BACKGROUND OF THE INVENTION
The present invention relates to shaving brushes and particularly
to a shaving brush for receiving a charge of aerated shaving cream
discharged from a pressurized aerosol container.
The instant invention is directed toward providing for the
convenient brush application of shaving cream dispensed from a
standard pressurized container. While the prior art discloses
various brush arrangements directed at achieving a like purpose
they have not been widely accepted for one reason or another.
The present invention importantly is for use with conventional
pressurized containers without necessitating costly alteration of
their existing valve structures as is the case with some of the
prior art devices. The brush component of the present invention is
usable in a convenient manner with existing pressurized containers
which, to a large extent, are standardized in both size and details
of construction.
The prior art devices, for the most part, do not embody brush
structures usable with existing pressurized containers while the
instant brush structure lends itself to low cost production methods
and more importantly, one not requiring modification of existing
pressurized containers.
SUMMARY OF THE INVENTION
The brush invention is embodied within a shaving brush and
stem-like holder with the latter serving a secondary purpose of
keeping the brush passageways clear of dried shaving cream. A
vertical bore constitutes a passageway for the delivery of the
shaving cream through the brush structure and is slidably
engageable, adjacent its lower terminus, with the valve orifice of
a pressurized shave cream container. The brush handle is annularly
shaped at its lower end to assure operative, reciprocal movement
relative to the container to actuate the container valve. Included
in the present invention is a brush stand having a stem on which
the brush is stored. Removal of the brush body from the stand,
extracting the stem from the passageway, results in the passageway
being left clear for the flow of shaving cream therethrough.
An important object of the present invention is to provide a
shaving brush conveniently stored when not in use, on a stand and
which when removed therefrom has an open passageway for the
unrestricted flow of shaving cream therethrough. A further
important object is the provision of a shaving brush adapted to
momentarily engage the discharge end of a pressurized container to
receive a charge of shaving cream. The brush body is shaped at its
lower end to provide cooperating surfaces for sliding engagement
with corresponding container surfaces. Further, the brush body is
so shaped as to prevent the inadvertent discharge of the shaving
cream prior to engagement of the brush with container.
BRIEF DESCRIPTION OF THE DRAWING
In the accompanying drawing;
FIG. 1 is a frontal perspective view of the combined brush and
stand embodying the present invention,
FIG. 2 is a like view of the stand only,
FIG. 3 is an enlarged side elevational view of the brush body
sectioned along its vertical center line for purposes of
illustration with the upper end of a pressurized shaving cream
container shown spaced therebelow, and
FIG. 4 is a bottom view of the lower end of the brush body.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With continuing reference to the drawing wherein applied reference
numerals indicate parts similarly identified in the following
specification, the reference numeral 10 indicates generally a brush
body of cylindrical shape shouldered at 11 adjacent its lower
end.
Depending from the bottom shouldered area is a concentric annular
wall 12 having inner and outer vertical wall surfaces 13 and 14 the
former wall defining a central, upwardly extending bore 15. A
counterbore at 16 extends upwardly from bore 15 with an
intermediate conical surface 17 extending therebetween. The
counterbore 16 terminates upwardly in a shoulder 18 which as
described later comes into bearing contact with the valve end of
the pressurized container.
Extending centrally through the brush body 10 is a passageway 20 in
communication at its lower terminus with the counterbore 16 and
thereat defining the shoulder 18. The passageway 20 terminates
upwardly in communication with a delivery tube 22 which is inset at
its lower end into the brush body with the upper portion of the
tube extending into the brush bristles at 23. A flow of shaving
cream is hence conveniently discharged into the upper portion of
the bristles from tube 22 which is of a height less than that of
the bristles so as to not interfere with bristle movement during
use. The bristles 23 may be secured to the brush body in the
conventional manner.
The stand as shown in FIG. 2 includes a base 24 from which a stem
25 extends with the stem being of a length sufficient to occupy
brush passageway 20 and tube 22 when the stand and brush are
combined. Further, it is desirable to form stem 25 of a diameter
only slightly less than the passageway and tube inside diameters to
insure complete displacement of residual shaving cream left in the
passageway.
With attention to FIG. 3, in use the brush body 10 and particularly
the inner and outer wall surfaces 13 and 14 are brought into
sliding axial engagement with corresponding walls at 24 and 25 of
the container C. Annular wall surface 14 initially contacts the
upper rim 25a of wall 25 with annular wall surface 13 subsequently
coming into contact with the container wall 24. Continued downward
movement of the brush body assures coaxial alignment of said body
and the pressurized container. A depressible valve stem at 26 of
the container constitutes a discharge orifice engageable with the
counterbore 16 in the brush body with alignment being achieved
prior to such engagement. The end of valve stem 26 eventually seats
against the shoulder 18 with continued downward movement of the
brush body actuating the internal valve mechanism within the
container. The released aerated shaving cream is ultimately
discharged from tube 22 into the upper ends of the bristles.
After use of the brush in the normal manner replacement of the
brush onto the stand results in stem 25 substantially occupying
passageway 20 and tube 22 whereby extraction of the stem at a later
time leaves an open passageway and tube to insure the unobstructed
passage of shaving cream as earlier set forth.
