Patented Mar. 24, 1953 UNITED STATES PATENT OFFlCE 2,632,446 DISPENSING RAZOR emote Sam Rosenzweig, New York, N. Y. Application April 26, 1949-, Serial No. 39,553

2 Claims.

This invention relatesto a safety razor handle, particularly toa handle having liquid styptic dispensing means therein. I i

It frequently happens during shavingwith a safety razor that the user will advertently slide the razor sideways or otherwise manipulate it in a manner and to such an extent that the skin is cut slightly. Small projections on the skin are also often cut slightly when shaving with a safety razor even under optimum conditions of use.- Suchcuts are characterizedby profuse and prolonged bleeding unless treated promptly with astyptic, such as alum. lior this reason it is common practice for men who shave regularly to keep a supply of a" styptic or astringent, generally a stick or pencil of alum, at hand which can be applied to a razorcut to stop bleeding. This necessitates an additional ar'ticle to be included among the already numerous articles necessary for shaving and is thus undesirable.- Furthermore, such alum sticks are seldom kept in a containe'r and thus tend to contaminate and corrode other articles with which they come in contact. This is particularly disadvantageous for travelers as is readily apparent. I V

A further and principal objection to the use of a solid styptic or astringent agent for treating cuts or wounds in the skin is due to the fact it must be: rubbed into the wound so that suflici'ent of the agent can dissolve in the fluids in the wound to exert thedesired effect. This is often painful, especially after the piece of styptic has been used and its surface has become roughened. Furthermore, the repeated use of a styptic pencil is liable to lead to the introduction into the wound of oertain' types of infectious organisms which are not devitaliz'ed by the particular styptic substance used.

It has been suggested to incorporate a container for a styptio pencil in the handle of a razor so that the styptic would at all times be at hand when needed and would not become misplaced and so thatits storage between uses would be facilitated and certain of the above-mentioned disadvantages overcome. However, none of the handles suggested have been adapted to the use of a liquid'styptic, astringent or antiseptic and the principal objection to the use of solid astringents hastherefore-not been overcome by such devices. Even inthe case of handles adapted to contain styptic pencils, thepencil must be removed from the handle before using and its use is, therefore, unhandy and devoid of desirable automatic features.

Itis, therefore, an object of the resent in-' 2 vention to provides handle for a razor adapted to contain a liquid sty'pti'c, astringent or anti septic. q p r An additional object is to provide a razor handle adapted to dispense a liquid astringent automatically and at a controlled rate.

An additional object is to provide a razor handle for containing and for applying a liquid astring'ent to an open wound with a minimum of irritation of the wound.

These and related objectsare accomplished readily and economically by providing in the handle of a razor, preferably a razor of the safety type having a shaving head in which a new blade .ean be inserted when the old one has become drilled, a receptacle for containing a fluid styptic, antiseptic or astringent, herein referred to generically as an antiseptic, and means associated therewith to dispense the fluid antiseptic on the skin surface, or in a wound or abrasion therein, by merely contacting the dispensing means lightly with the area which it is desired to treat with the antiseptic. To prevent the application of undue amounts of the antiseptic, e; g. by macv'ercemand undesired flooding of the antiseptic onto the treated area, means are provide to regulate the rate of flow of the fluid antiseptic during the application thereof and, to prev nt loss'of fluid by accidental spillage or evaporation, means are usuauy provided for sealing the device against such loss between uses, such means preferably operating automatically in such fashion that the device is normally sealed except when fluid is actually being dispensed therefrom.

Figure 1 is an elevation, principally in section, of a razor having a handle embodying one modifioation of the invention.

Figure 2 is an elevationpartly in section, of a dispensing razor handleembod ying an alternative modification of the invention.

Referring now to Figure 1, there is shown a razor having a conventional shaving head comprising blade-clamping members [0' and H, a blade 12, and positioning studs 13 secured, e. g. bya threadedstud 31 in conventional fashion, at one end of the main body member I4 of a handle comprisingone modification of the invention.

The handle body member 14 is formed to comprise areceptacle, chamber or cavity I5 for holding a fluid antiseptic. The handle body member I4 is usually cylindrical but may be square, Bct'angular' or ofany other convenient or desirable cross-sectional shape and the fluid chamber is generally elongated to enabiea suitable su ply of liquid to be contained therein.

The chamber i5 is closed at its outer end, i. e. at its end farthest removed from the shaving head, with a dispenser body member l5, conveniently a somewhat elongated annular body threaded externally on its inner end and adapted to be screwed into threads ll formed internally at the outer end of the hollow section of the handle body member M. A dispenser body bore 18, preferably cylindrical in cross-section, extends longitudinally through the dispenser body member 16 and is constricted somewhat and formed at its outer end to provide an annular seat i9 facing inwardly of the bore and adapted to receive a smooth surfaced ball 20 having a diameter somewhat less than the diameter of the bore l8 to form a liquid-tight seal. The annular seat I9 is preferably of a suitable diameter to permit the ball 20 to project substantially beyond the farthest outward extension of the dispenser body member I6 and the outer end 2! of the dispenser body member is preferably rounded and otherwise formed and polished so as to present with the exposed surface of the ball 29 a smooth, sub stantially continuous surface which causes a minimum of irritation when rubbed gently over an abrasion or open wound.

A tubular piston 22 open at its inner end is positioned in the longitudinal bore [8 of the dispenser body it and is of such a diameter that it slides easily in the bore. The outer end of the piston 22 is closed with a piston head 23, which is conveniently flat and which contains one or more piston head ports 25 to permit free flow of fluid through the piston head 23. At least one of the piston head ports 24 is located offcenter so that it is not closed when the piston head 23 and the ball 29 are in firm contact. A spring 25, conveniently a coiled spring under compression, is positioned inside the tubular piston 22 and bears at its outer end on the inside of the piston head 23. The inner end of the dispenser body bore 18 is closed with a spring-retaining member 25, against which the inner end of the spring 25 bears and which is secured in the bore IS in any convenient fashion and provided with one or more spring-retaining member ports 21 permitting free fiow of fluid between the fluid chamber l5 and the dispenser body bore 18.

The spring-retaining member 26 can conveniently be a close fitting plug which is pressed into position or it can be a threaded member which can be secured by means of threads formed in the surface of the bore [8. The spring-retaining member 26 is preferably adapted, e. g. formed with a flange 28 at its inner end somewhat greater in diameter than the diameter of the dispenser body bore l8, to extend only to a predetermined distance into the bore l8.

Under normal conditions of storage and use of the razor, the tension of the spring 25 keeps the piston head 23 tightly pressed against the ball 20 thus pressing the latter firmly against the annular seat !9 to seal the device and prevent passage of liquid or vapor between the ball and the seat. When, however, the ball is rubbed or rolled alon the skin, as in treating a small cut, the spring 25 is depressed slightly by the pressure of the skin on the ball and the ball is displaced from its seat sufiiciently to allow a thin film of liquid to adhere to the ball and to be deposited on the skin as it rolls along the surface of the skin.

To limit the rate of flow of the liquid to a desired predetermined value and to avoid its flooding onto the skin, it is preferable that the wall of the piston 22 be of such a length that it 4 abuts against the spring retaining member 26 when the tubular piston 22 has moved inwardly for a predetermined distance in the bore [8 and the ball has been unseated to the desired extent. A travel of a few thousandths of an inch for the piston will generally be sufficient.

Liquid styptic or other agent can be loaded into the chamber 15 by disconnecting the dispenser body member 16 from the handle body member M, as at IT, and filling the chamber 15 as desired. To prevent leakage, a thin gasket 29 can be employed in conventional fashion between the dispenser body 16 and the handle body member M. A cap 30 of conventional design can be removably secured, e. g. by friction, over the outer end of the dispenser body 16, if desired, to protect the ball 20 and the polished surface 2| when not in use.

In an alternative arrangement of the parts as shown in Figure 2, the dispenser body member [6 is connected with, e. g. by being pressed or threaded into the outer end thereof, a receptacle member 32 having a, receptacle 36 therein which is separate from the handle body member l4 and which is secured therein in any convenient way. e. g. by threads 33. The inner end of the receptacle member 32 can be closed in convenient fashion as by a threaded or friction plug 34. A fine capillary opening or port 35 can be drilled in the plug 34, if desired, to assist in equalizing pressure between the receptacle 36 and the cavity iii in the handle body member I4. Equalization of the pressure in the receptacle 35 with the atmospheric pressure is generally effected when the ball 20 is unseated for the application of the antiseptic.

Although the preferred applicator means comprises a ball arranged substantially as in Figure 1, other applicator means can be used, if desired, provided limiting the rate of flow of the antiseptic during use of the device to prevent flooding is effected. An alternate arrangement can comprise a wick suitably constricted to limit the rate of flow of the antiseptic to a desired value or other means equivalent thereto.

I claim:

1. A razor handle comprising in combination a handle body member having a receptacle closed at its inner end for containing a fluid, a dispenser body member secured to the outer end of the handle body member and closing the outer end of the receptacle, a longitudinal dispenser body bore through the dispenser body member communicating with the receptacle at its inner end and constricted at its outer end to form an annular ball seat, a tubular piston in the bore adapted to slide easily therein and closed at its outer end with a head having a port for the flow of liquid therethrough, a ball retained between the piston head and the annular ball seat and adapted to form a liquid-tight seal when seated on the latter, spring-retaining means secured to the inner end of the dispenser body bore having a port for the flow of fluid therethrough, and spring means under compressive stress positioned inside the tubular piston and bearing on the spring-retaining means and on the piston head for maintaining the piston head and ball normally in firm contact with one another and the ball firmly seated, the ball projecting through the annular ball seat and being movable inwardly of the bore against the pressure of the said spring means in response to external pressure to allow passage of fluid between the ball and the seat.

2. The combination as claimed in claim 1 wherein the spring-retaining means is positioned so as to lirriitthe inward travel of the piston and of the ball in response to external pressure on the ball and ,iirevent flooding between the ball and seat of a fluid contained in the fluid receptacle.
