Razor with pre-wetting or capillarizer system

A safety razor including a replacable container inserted into the handle, the container having a pressurized beard-wetting agent therein that is dispensed in selected amounts, by a mechanism, toward the razor head where foam rubber pads absorb the agent and dispense it onto the skin in front of the blade edge.

This invention relates generally to safety razors. 
It is well known that a person must first lather up a beard so as to soften 
the hairs before they can be easily shaved off. Accordingly, up till now a 
lathering soap in a shaving mug has been applied by a brush, or else a 
soap dispensed foaming from a pressurized can was first dabbed on the skin 
and rubbed in by a person's fingers before a razor was applied for 
shaving. These preliminary steps required extra equipment and took extra 
time. 
Accordingly, it is a principal object of the present invention to provide a 
razor having a self-contained beard pre-wetting system that eliminates any 
preliminary beard softening operations prior to shaving, so as to save 
time and do away with any other extra equipment cluttering a bathroom 
medicine cabinet. 
Another object is to provide a razor with pre-wetting or capillarizer 
system that is adaptable for use in either a standard double or single 
edge safety razor, and which is adaptable for both men's or women's safety 
razors. 
Still another object is to provide a razor with pre-wetting or 
cappillarizer system which does not require and use of water.

Referring now to the drawing in greater detail, and more particularly to 
FIGS. 1 and 2 thereof at this time, the reference numeral 10 represents a 
safety razor according to the present invention wherein there is a handle 
11, and a head 12 mounted on one end of the handle and consisting of a 
conventional pressure plate 13 and a clamp plate 14 that serve as guards 
between which a razor blade 15 is held, the clamp plate having a threaded 
stem 16 extending through the pressure plate and screwed in a threaded end 
of a hole 17 in the handle. 
In the present invention, a foam rubber pad 18 is placed between the clamp 
plate and the razor blade, the pad being coated on opposite sides 19 and 
opposite end edges 20 with a waterproof sealant 21. A central hole 22 
through the pad clears the stem 16 passing therethrough. 
Also in this design a foam rubber pad 23 is applied around each leading 
edge 24 of the pressure plate, the edge being either conventionally 
toothed or being annularly grooved rotatable roller. 
Additionally in this design the handle is hollow and has a removable, 
screw-on end cap 25 so as to permit insertion of a replaceable cartridge 
26 therein which contains a pre-wetting agent under pressure. A valve 27 
within one end thereof includes an outwardly extending stem 28 which when 
depressed causes the agent to be dispensed around the stem. The cartridge 
is located between a compression coil spring 29 and a push button 30 
slidable in the end cap so that when the push button is depressed, the 
cartridge is moved against the spring and causes the stem 28 to abut 
against a transverse pin 29A in the handle so as to open the valve and 
allow the pre-wetting agent to be dispensed into the hole 17. From there, 
it is pushed through a central hole 30 in the clamp plate stem and into a 
transverse hole 31 thereof and into the central hole 22 of the pad from 
where it saturates into the pad 18. The opposite sides 32 of the pad being 
left uncoated with the sealant, allows the pre-wetting agent to be 
dispensed outward therefrom and upon a skin and beard, in a vicinity of 
the blade cutting edges 33. Thus, the agent also transfers therefrom to 
the pads 23 so that the blade cutting edges are surrounded on both sides 
with the pre-wetting agent that softens the beard and required no water 
being used. Thus, the beard is easily prepared for shaving by simply 
depressing the push button, and requiring no additional equipment clutter, 
such as shaving mug brush or separate pressurized soap can. 
In FIG. 3, a single edge injector razor 34 includes foam rubber pads 35 and 
36 above and below the blade cutting edge, the pad 35 being thicker so to 
store the agent during a shaving operation. 
In FIG. 4, the double edge razor 37 is likewise equipped with the pads 35 
and 36. 
In FIG. 5, another model of double edge razor 38 is of narrow type and 
includes a foam rubber pad on its underside for dispensing the agent to a 
roller 39 closely aligned to the blade edge and rolling the agent on the 
skin and beard hairs. The handle contains a cartridge 40 having a 
pressurized container 41 containing the pre-wetting agent for dispensing 
from a hole 42 of the razor head and into which the container valve stem 
extends. A cord 43 pulls on a piston 44 against a compression coil spring 
45 a bead 46 affixed along the cord being moved outward of a hole 47 in 
the end of the cartridge so as to be locked behind a slot 48 and thus 
allow a slow steady dispensing of the agent during a shaving operation. 
A cartridge 49 shown in FIG. 6 includes a container 50 containing the 
agent, and a compressed air chamber 51 containing a piston 52 bearing 
against the agent container. A compression coil spring 53 bears at one end 
against the container and bears at its other end against an end wall 54 
fitted with a check valve 55 for charging the chamber with air.
