Description
BACKGROUND OF THE INVENTION
Lorenzo Lopez, Jr. disclosed a shaving device in his U.S. Pat. No.
4,023,269 including a razor blade and a supply of shaving cream in
a device for convenient shaving. However, such a conventional
shaving device has the following drawbacks in use:
1. Even the operator 81 is depressed to open a valve of the aerosol
container 18, the valve stem is not made as an inclined surface to
mate with the inclined surface of the operator 81 as shown in his
FIG. 2 so that a heavier force is required to depress the operator
81 bearing against a strong force exerting on an acute edge of the
valve stem resiliently actuated by a valve spring inside the
aerosol container.
2. By depressing the operator 81 to push the valve stem inwardly
through the opening 20, a shaving cream will be discharged through
the passageway 52 towards the brush 36, of which the passageway 52
is very long to easily cause contamination or curing of the cream
as kept in the passageway.
3. When the operator 81 is suddenly released from the seals 84, the
acute edge of the valve stem as tensioned by a valve spring and the
pressurized cream in the aerosol container 18 may forcibly bias (or
even brake) an inner end of the operator 81 to slow down the
recovery or outward protruding of the operator, especially
frictionally held by packing seals 84, thereby possibly causing
cream leakage due to a difficulty for sharply closing the aerosol
valve.
The present inventor has found the drawbacks of the conventional
shaving device and invented the present fountain shaving device
overcoming the above-mentioned drawbacks.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a fountain
shaving device including a brush mounted on one end of an aerosol
container of shaving cream, a razor means mounted on the other end
of the aerosol container, and a push-button controller operatively
depressible for opening an aerosol valve for directly discharging a
shaving cream from the aerosol container into the brush bristles
for convenient shaving purpose.

DETAILED DESCRIPTION
As shown in FIG. 1-3, the present invention comprises: an aerosol
container of shaving cream 1 also serving as a handle, a brush
means 2 mounted on a first end portion 11 of the container 1, a
shaving-cream despensing controller 3 mounted on the first end
portion 11 of the container 1 and mounted in the brush means 2, and
a razor means 4 mounted on a second end portion 13 of the container
1 opposite to the first end portion 11.
The aerosol container of shaving cream 1 includes: an aerosol valve
12 mounted in the first end 11 of the aerosol container 1 having a
central hollow stem 121 longitudinally reciprocatively mounted in a
central opening 111 of the first end portion 11 normally protruding
outwardly as retained by a tensioning spring 124 seated on a
cartridge 125, a lower plug 122 formed on a lowest end of the stem
121 operatively sealing a valve opening or seat 123 of a valve
cartridge 125 internally secured to the first end portion 11, and a
cream outlet port 120 formed in a lower portion of the stem
positioned above the plug 122 and being normally excluded from any
inlet cream by closing the plug 122 on the seat 123 of the valve
cartridge 125. The valve 12 can be selected from any other
conventional designs or modifications to have a central hollow stem
121 operatively depressible for opening the valve, and normally
protruding outwardly from the container 1 without depressing of the
stem 121.
The razor means 4 includes a socket 41 for mounting a second end
portion 13 of the container opposite to the brush means 2 and a
holder portion 42 for connecting a blade cartridge 43 containing
shaving blades thereon.
The brush means 2 includes a plurality of bristles 21 planted on a
base plate 22, and a cylindrical portion 24 formed under the base
plate 22 secured to the first end portion 11 of the container 1,
defining a cylindrical chamber 25 among a bottom flat surface 23 of
the base plate 22, the first end portion 11 of the container and an
inside wall of the cylindrical portion 24 to generally encase the
dispensing controller 3 in the chamber 25. A cover 26 may be
provided to protect the bristles.
The shaving-cream dispensing controller 3 is an essential means of
the present invention and includes: a longitudinal dispenser 31 and
a lateral actuator 32.
The longitudinal dispenser 31 includes a central guide tube 311
having its inner tubular hole coaxially engaged with the central
hollow stem 121 of the aerosol valve 12 having an annular extension
312 of the tube 311 engaged with an upper edge of the stem 121, and
a disk portion 313 formed on a lower end of the tube 311
perpendicular to the tube 311 having a first inclined surface 314
tilting downwardly outwardly.
The lateral actuator 32 generally perpendicular to the dispenser
tube 311 includes a push-button portion 321 normally protruding
outwardly through a slot 241 formed in the cylindrical portion 24;
a bifurcate wedge portion 322 protruding inwardly opposite to the
push-button portion 321 to tangentially dispose around the tube
311, having an upper flat surface 324 coplanar to an upper flat
surface of the push-button portion 321 laterally sliding along the
bottom flat surface 23 of the brush base plate 22 and having a
second inclined surface 323 formed on a bottom of the wedge portion
322 tilting upwardly inwardly to be slidably engageable with the
first inclined surface of the longitudinal dispenser 31; and a
restoring spring plate 325 retained between the bifurcate wedge
portion 322 and an inside wall of the cylindrical portion 24
normally pushing the actuator 32 outwardly to protrude the
push-button portion 321 beyond the slot 241. The brush means 2 may
further include a cap 26 for hygienic purpose.
The central guide tube 311 has its outer tubular wall
reciprocatively engaged in a shallow jacket 221 formed in a central
portion of the base plate 22, The guide tube 311 is fluidically
communicated with the central hollow stem 121 and has its upper end
poking into a bundle of bristles 21 of the brush means 2.
When using the present invention for shaving purpose, the
push-button portion 321 is depressed inwardly as shown in FIG. 3 to
allow the second inclined surface 323 to thrust the first inclined
surface 314 of the longitudinal dispenser 31 downwardly to lower
the central stem 121 of the aerosol valve 12, thereby discharging a
shaving cream 10 through the port 120, the stem 121 and the tube
311 into the brush bristles 21 for direct distribution of cream
onto a man's skin. When releasing the push-button portion 321, the
spring 124 will resiliently raise the stem 121 and the dispenser
313 to allow the first inclined surface 314 to thrust the second
inclined surface 323 of the lateral actuator 32 to recover the
outward protrusion of the push-button portion 321, also laterally
restored by the spring plate 325.
Naturally, the spring plate 325 may also be omitted when the
aerosol spring 124 is strong enough.
As shown in FIG. 4, the razor means 4 may be omitted so that the
brush 2 is mounted on an aerosol container 1 filled with shaving
cream.
As shown in FIG. 5, the razor means 4 is mounted on the first end
plate 11 of aerosol container 1, The holder portion 42 of the razor
means 4 may be formed with a tube hole 421 therein to substitute
the shallow jacket 221 of the brush means 2 so that the tube 311 is
reciprocatively operated in the hole 421 when depressing or
releasing the push-button portion 321.
The present invention has the following advantages superior to a
conventional shaving device such as taught by Lopez's U.S. Pat. No.
4,023,269;
1. The shaving cream is directly and immediately distributed into
the brush bristles by merely push button operation for convenient
and hygienic using of cream.
2. The longitudinal (vertical) dispenser tube 311 coaxially
linearly connected with the aerosol valve stem 121, both tube 311
and stem 121 slidingly held in two plates 22, 11, can be stably
operated without causing a serious braking or twisting action
between the lateral push button and the aerosol valve stem, when
slidably thrusting the two inclined surfaces 314, 323 by depressing
or releasing the push button 321.
3. The bifurcate wedge portion 322 of the lateral actuator has two
arms tangentially disposing around the central tube for ensuring a
sharply slidable engagement of the two inclined surfaces 323, 314,
as assisted by a stable lateral sliding movement of the actuator 32
transversely reciprocating in the chamber 25 of the cylindrical
portion 24 of the brush means 2, so that a transverse (horizontal)
movement of the actuator 32 is very stable in commensuration of a
stable longitudinal (vertical) movement of the dispenser 31,
resulting in a very smooth depression operation of push button when
opening an aerosol valve or a smooth recovery of push button when
closing the valve.
The lateral actuator 32 of the dispensing controller 3 can be
modified to have variable adjusting means, such as by forming
scales on the actuator (not shown) or other stepwise control means
so as to adjust the discharge quantity of shaving cream.
