Application October4 14, 11953,?Se`rial No. :385,988 `6 Claims. (Cl. .S0-'32) This invention relateslgenerally lto advertising -devices of a utilitarian nature andparticularly to an? inexpensive, disposable safety razor.

An IobjectV of the invention is toiprovidea very simple, yet highly practical, safety razor constructed asamolded plastic article having a razorbladeernbed'ded in the plastic material with its cutting edge exposed for V`use in shaving.

Another object of the invention is to provide e safety razor having a molded plastic'bod'yor holder .formed with a razor head at one end, the vremaining-.portionof the -body providing a'handle by Which-themazorcanvbe manipulated when shaving.

Another object of Ithe invention'is t-ofpro'vide -a safety razor, 'of the character referred to, in which said-head is of a shape closely'-simulatirlg'onehalf of the I'head of a conventional safetyraz'or,"`the lhead havingfaconvex face-engaging "surface overlying' the vblade and a "serrated or slotted guard portionfunderlyi'ng the bladeedg'e -a'n'd 'forming a guard.

Anotherobjectv of the invention is i tofprovide *afdisp'os- `ablesafety razorlof the Ytype ndicatedhavinga thin,`tear away strip of the plastiornateri-al'molded over'thefcutting edge'of the blade,` said strip 1bei`n`g=separable lfrom the headlengthwise of therblade'edge touncover the Vsame and thusex'pose it foruse, the :strip thus -providin'ga vsanitaryand safetyfseal forfthe cutting edgeof the blade.

-Another objectof-theinvention is toprovide a disposable safety razor of the type'specitied in- -which the bladepreferably consists fof one-half of faiconventional,

double-edged razor blade, the conventional thin, steel -a coat Yorin Aa compartment of 'alsuitcasa the farticle being particularly adaptable for useby travelingrnen, military personnel, etc.,'not wishing to carrythe usual shaving equipment. In additio'mthe razor is'of 1a ysize lending itself to dispensing-from a vendingama'chine and, due to its extremely low-cost,the1article may' bezprovided free of Icharge tothe guests ohotelsfandother establishments catering Yto transients, the back surface andthe portion of Vthe razorbody beneath the -headrproviding unobstructed surfaces upon which advertisingm'tter'inay be `applied by printing or bymoldirg' 'the same thereon.

A further object of'tne' invention 'isit'oprovide 'la' molded article ofthe character'i'eferred to'above Whichpr'eierably has a recess or cavityinits'rearward side, said recess providing a` shallo'wreceptacle 'or 'compartment for containing `a lsupply of'lathe'ringsoap or shaving "cream nfor applying'totheface prior to usingtlre'razor, theilth- Inited States Patent 'tutes a convexskin-engaging' surface.

Referring tothe `drawingeindetail,vthefprcsent safety razor is AVillustratedin Figs. l to 3 Aas approximately-`one and one-halt' times its-actual size, the razorthu-s lbeing of substantially vthe same size as an ordinary rnatch'book. The razor has a holder or body 10 which includes a rectangular central plate' portion El and a lowendhicker, rectangular portion 12, -these portions togetherprovidin'ga 'handle 'adapted to beheld in a hand.

`15 yand lower portion 12-are side anges or wings y22.

VFormed in the rear side of thelower'portion 12 is a rectangular recess or compartment 23.

The holder Ior body 1'0 is molded from a'ther'mo-setting -plastic material so ast-o minimize the costthereof. -P`rior `to injection of the plasticito the cavity 'of 'the mold, 'the LArazor blade 20`is placed in the cavity and against a `pernianent magnet therein which retains the blade :in

place. 'Whenth'e pla'stic 'material is injected intoi'tlie cavity of 'the mold,it flows aroundthevbladel't-o provide 'the headIS in whi-ch 'all but a small'lowerfportion of =the cutting edge (19 of the blade is embedded. The cavity=is -sofformed'as to cause the plastic materialfto -extendfacross the cutting edge -191in a very thin'bead or strip Z5 which encloses the cutting/edgefor vlsanitary and safety reasons. The razor blade v 20is preferablyyalthough notnecessarily, made from-a conventional double- -edged razor blade, ithe latter being broken along Yits 'median line to v'divide it'into a pair of single-edged blades.

To apply'tlie razor to use, the user holds it in one -hand and' then graspsanendof tle strip 25'be'tween theA thumb 1arid index'nger of "the other hand. The 'strip'is'then pulled laterally across the -razor tofpeel o'rtearthe strip from across theicuttingedge 19`of theblde,"so astoexposethe' "cutting edge, itlbe-ing noted .by rfencetoFig.

3 4 that this edge projects slightly beyond the forward side of the head 15. The razor is then in condition for use.

After l-athering the face, the user holds the razor in upright position, grasping the anges Z2 between the ythumb and foretinger. The razor then may be drawn across the skin to shave the whiskers therefrom in the manner of an ordinary safety razor. During such shaving, the lather and whiskers will enter the shallow -receptacle 26, defined by the central portion 11, lower portion 12, wing-s 22 and the guard 18, to be collected therein. Excess lather may be ilushed from the receptacle at lany time by simply subjecting the razor to the force of 1a stream of tap water.

After completing the shaving operation, the user deposits the entire razor in a waste basket or other receptacle to dispose of the razor which, as previously indicate-d, is a very inexpensive item adapted for .a single use.

lt is Within the concept 'of the invention to provide a dispensable material within the receptacle or compartment 23. This material preferably is of a whisker-lather ing nature, such as dry particles of shaving soap. A small Wad 3i) of cellular material may be impregnated with the soap particles, the wad being cemented or otherwise retained -in the compartment 23. Prior to the actual shaving operation, the wad is -moistened to create a lather which then may "be 'applied to the skin of the face of `a man, or to the legs of a woman who may wish to shave hairs from the legs.

lIn lieu of the soap-impregnated wad 30, a llexible envelope 33, containing lathering cream 34, may be secured within the compartment 23. When it is desired to :apply the cream 34, the envelope 33 may be easily punctured and squeezed or compressed to lforce the cream `from the envelope.

Referring now to Fig. 7, -it is also within `the present concept to provide a disposable razor in which the body thereof is molded from la flexible, heat-sealable plastic material, such as polyethylene. In this embodiment, the body -is molded with an integral envelope portion 32 having thin walls and an open end arranged either at a side or at the lower end thereof. The envelope portion 32 provides a receptacle into which brushless or lather cream may be placed. The edges of the open end then may be sealed together, as indicated `at 31, by the application of heat and pressure to seal the envelope. To prepare the whiskers for shaving, the envelope 30 is punctured to release the Whisker-softening medium which is then applied to the face prior to the shaving operation.

It will be observed from the foregoing that the present invention provides a simple, yet highly efficient and practical safety razor of a disposable type adapted for a l.single use. The razor is molded with an integral head in which the blade is partly embedded, thus avoiding the necessity Ifor inserting and clamping a blade at the time of shaving. The razor is 'of light weight, yet strong construction and may be mass produced at a very low cost. The razor, which is of substantially the same Isize and shape of a match book, provides an excellent advertising medium, the body of the razor having Hat surfaces to which may be rapplied ladvertising decals or printing, or which may be embossed with advertising indicia during the molding of the razor.
