Claims
What is claimed is:
1. A shaving razor having a bottom plate, a support member
extending from one edge thereof, and a cylinder rotatably disposed
in said member and having a perforated surface adapted to pass
lubricant from the interior of the cylinder, a lubricant supply
member is, a wick, said wick extending into both said supply member
and said cylinder to pass the lubricant from said supply member to
said cylinder.
2. A razor as defined in claim 1 wherein said support member is a
channel extending longitudinally from one edge of the bottom
plate.
3. A razor as defined in claim 2 wherein said cylinder is hollow
and a channel extends from each side of the bottom plate, said
cylinder being rotatably supported in each channel.
Description
This invention relates to attachments for safety razors and in
particular to razors having a moisture or lubricating chamber
adapted to dispense its content disposed in advance of the action
of the razor's cutting edge.
While the use of moisture-supplying components in conjunction with
safety razors is known, e.g. U.S. Pat. No. 2,600,880, it is new to
provide a razor having this accessory feature which combines the
ability to depose the moisture or lubricant uniformly and
simultaneously to stretching the skin prior to the act of shaving.
This capability is achieved by means of rotatable cylinders having
macroscopic holes in their surface through which the fluid is
metered continuously and evenly during rotation thereof regardless
of the pressure the user of the razor exerts on the face. Further,
the hollow cylinders are adapted to be supplied by a separate and
renewable supply of the fluid to assure an uninterrupted source for
a relatively, extended period of time.
One object of the invention is to provide a new and improved razor
head for stretching and lubricating the skin prior to shaving.
Another object of the invention is to provide an improved
lubricating razor head containing a supply of lubricant with means
for insuring that such supply will last for comparatively long
periods of normal use.
Other objects and advantages of the invention may be appreciated on
reading the following description of one embodiment of the
invention which is taken in conjunction with the accompanying
drawings, in which:
FIG. 1 is an exploded perspective view of the invention showing the
lubricating means detached from the razor;
FIG. 2 is a plan view of FIG. 1 in assembled relation;
FIG. 3 is an end view of FIG. 2 as seen from the left; and
FIG. 4 is a cross section taken on the line 4--4 of FIG. 2 showing
the retention means for rotatable cylinders.
Referring to the drawings, razor 6 is provided with a handle 8 and
head 10. The head 10 comprises a bottom plate 12 and a top plate 14
removable on the threaded end of the handle to accommodate a razor
blade 16 therebetween.
The plate 12 is provided at each longitudinal edge with a channel
18 semi-circular in cross section into which cartridge cylinders 20
are disposed. Macroscopic holes 22 are provided in the surface of
the cylinders to permit communication with their interior and the
uniform dispensing of lubricant contained therein as the cylinders
are turned on their own axes within the channels 18.
The cylinders 20 are removably connected to and in communication
with plastic bulb 24 through wicks 26, which serve as a reservoir
for the lubricant.
When the razor is in use, as seen in FIG. 4, the cylinders 20
function to stretch the skin and lubricate the area immediately
ahead of the blade. As shown in FIG. 1 the cylinders 20 are
removable, if desired, from the channels and detachable from the
lubricant supply for renewal of the latter. As the razor is moved
across the face the cylinders 20 roll on their own axes to press
and stretch the skin while the macroscopic holes 22 feed lubricant
thereto which has been obtained from the wicks 26. The pressing,
stretching and lubricating of the skin occurs prior to the actual
shaving operation.
