10 Claims.

This invention relates to razor blade packages and refers more particularly to supports carrying the razor blades and wrappers enclosing the same.

Heretofore safety razor blades were packed individuaily in oiled paper or impregnated paper and were enclosed in a paper envelope. Five, ten or a larger number of suchenvelopes were packed together in packages made of heavier paper or cardboard.

Practical experience has shown that this method of wrapping razor blades does not prevent the sharp edges thereof from rubbingv against the paper wrapping so that in many instances the ends become dull before the user removes the razor blade from its wrapping for the first time.

This wrapping for razor blades is also inconvenient in so far as it is necessary for the user to open the paper envelope to produce the razor blade wrapped in oiled paper, then take oil' the oiled paper and finally place the razor blade upon the safety razor. All these manipulations must be done by hand and the razor blade must be held by the user before it is deposited upon the safety razor.

Every day experience shows that the fingers or the hands of the user are frequently cut by the sharp edges-of the safety razor blade while such razor blade is unwrapped and placed upon the safety razor. A

During the unwrapping the shaving edges of the blade must come in contact with the paper wrapping and may be dulled by this contact. The very nature of the blade prevents the user from holding it securely with the result that the blade is often dropped and damaged; furthermore, it is extremely inconvenient and dangerous to pick up the blade when it lies upon a fiat surface.

An object of the present invention is the provision of a razor blade support of such form that 40 any contact between the fingers or the hand of the user and the razor blade is avoided while the blade is being unwrapped and placed upon the safety razor.

Another object is the provision of a blade support which will eliminate the danger of injury to the user while he unwraps the blade and deposits the same upon the safety razor.

A further object is the provision of a wrapper for safety razor blades which will effectively protect the sharp edges of the blades while the latter are not in use.

The above and ether objects of'the present invention may be realized through the provision of v a blade support consisting of substantially water- (ci. zoe-4s) proof flexible material, for instance, a sheet of waxed cardboard. fibre, metal and the like, which carries the blade and which is wider and longer than the blade in order to prevent the user from being injured by the sharp edges of the blade.

The blade is attached to the cardboard support by any suitable adhesive, such as parafiln, or by any other suitable means. The cardboard may be provided with aline of perforations or indentations to enable the user to bend the sheetvof cardboard while holding the same and deposit the blade upona safety razor without touching the blade.

The adhesive connecting the blade with the cardboard support may be eliminated and the cardboard support may be shaped in such manner as to form a frame holding the blade while it is being deposited upon the safety razor. The blade and its support are preferably enclosed by an envelope of certain'stiifness having outstanding cushion-like edges which prevent the paper from coming in contact with the edges of the blade and thus prevent theseedges from rubbing against the paper while the blade is situated within its envelope.

"I'he invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawing showing, by way of example, preferred embodiments of the inventive idea.

In the drawing:-

Figure 1 shows a support carrying a blade;

Filgure 2 is a section along the line 2-2 of Figure Y Figure 3 illustrates a method of placing the blade carried by the support shown in Figures 1 and 2 upon a safety razor.

Figure 4 shows a razor blade support of a somewhat diflerent type;

Figure 4a is a section along the line la--l'a of Figure 4.

Figure 5 illustrates an envelopecarrying the blade and its support.

Figure 6 is a section along the line 6 6 of Figure 5.

Figure 7 is a perspective view of a blade support of a different type. The safety razor ill illustrated in the drawing may be of anystandard make and is provided with the usual central opening il through which projecting portions of a safety razor extend when the blade is placed in the proper position upon a safety razor.

The support i2 carrying the razor blade may 2 a,1aa,asa l be made of cardboard, ilbre or any other suitable ilrm but flexible or resilient material, the surfaces of which are preferably water-proofed by waxing or by any other appropriate means. Preferably,

5 the support I2 is of different resiliency than the blade I0.

The support I2 is wider and longer than the blade I0 so that when the support I2 is picked up by the fingers-of the user there is no danger that the user will be cut by the sharp edges of the razor blade I0.

The razor blade Il is glued to the surface I3 of the support I2 by parallln or any other suitable adhesive material. Preferably the adhesive materlal is placed upon the surface I3 of the support I2 in the form of four elongated strips I4, Il, I3 and I1. The strips I4 and I3 extend parallel to the strips I3 and I1 and are situated on op posite sides of the central opening I I of the blade.

Of course, the adhesive substance may be applied to the support I2 in any other suitable way.

Perforations or indentations Il extend across the entire support I2 and are'preferably situated in the middle thereof. In the support as illustrated, one row of perforations is shown, but the perforations may extend in two or more parallel rows.

The support I2 is provided with a central elongated opening I9 which is preferably somewhat longer than the corresponding opening IIof the razor blade III. z

The support carrying the blade I3 is situated in a paper envelope or wrapper 23 shown in Figures 5 and 6 which will be described in greater detail hereinafter.

The manner of using the blade support I2 is illustrated in Figure 3 `of the drawing. When ,the user removes the support I2 from the envelope his fingers do not come in contact with the blade It, since the support I2 is larger than the blade, so that he can hold the support conveniently between his nngers. In order to be able to place the blade it upon a safety razor (not shown), the user must hold the support I2 be tween the lingers of one hand and gently move the edge`2i of the support toward-its edge 22,

thereby ,bending the support I2 along 'the iii-- dented line i8.

The bent portion of the support I2 which car ries the layers oi.' adhesive I4 and i5 will easily separate from the adjacent portion of the razor blade, since the adhesive which is sufilciently strong to prevent the shifting of the blade within the envelope 2t is not strong enough to resist the pressure of the fingers. Then the user holding the bent support i2 by two or three dragers of one hand can easily place the clade i@ in the required position upon the safety razor which he holds in his other hand and thereafter remove 6o the support entirely.

Of course, the same result may be accomplished by moving both edges 2i and d2 toward each other simultaneously, while the middle portion of the support is pressed doumwardly upon the safety razor. another convenient method of application consists in holding the edges 2i and 32 by the thumb and middle finger of one hand and pressing the index finger ci? the same hand adjacent the :middle portions of the support, thereby dropping the blade in place.

It will be noted that in the course of this prov cedure there is no time during which the fingers oi' the user hold or come in contact with the blade itself, so that any danger of injury to the Vfingers or to the hand of the user is eliminated'.

The blade support 30 shown in Figures 4 and 4a of the drawing is provided with ilaps or bent-over portions 3l and.32 which hold the blade III so that the support has no adhesive or other additional means maintaining the blade I0 upon the 5 support 30. The flaps 3l and 32 are provided with cut-out portions 33 and 34, respectively. The razor blade I0 which is of standard construction, is provided with the usual projecting

end portions

35 and 36 which pass through the openl0 ings 33 ,and 34 respectively and fit snugly into these openings, so that any shifting of the blade I l upon the support 30 is prevented.` Obviously, the support 30 should be wider than its blade I0.`

The middle portion of the support I0 is prefl5 erably provided with two parallel ridges 3'I and 33 (Figure la) so that the blade l0 rests upon these ridges and not-upon the flat surface of the support. The ilap 3l is provided with similar parallel ridges 33 and 4.0, while the flap 32 is provided 20 with parallel ridges 4I and 42. By this arrangement the blade I0 is conveniently supported without contacting the entire surfaces of the support 33.

In order to place the blade upon a safety razor 25 the user must keep one flap, for instance the ilap 32, closed, and open the ap 3l, thereby freeing one end of the razor blade. e"I'his freed end of the razor blade is first placed upon the safety razor and then the support 30 is removed, leaving 30 the blade in its proper position upon the safety razor. The support 30 also will prevent injury to the fingers of the user, since at no time does the user hold the blade between his fingers while removing it from its envelope and placing it upon 35 the safety razor.

The envelope 2li which encloses the blade i0- and its support is shown in Figures 5 and 6 of the drawing.

The front surface of the envelope 20 is proel) vided with a central depressed fiat portion 23 and outstanding ridge portions 2d forming a frame surrounding the central portion 23. The frame portion 24 may consist of a large number o ridges 2d which are impressed upon the paper. d5 y The blade I II which is situated within the enveiope 26 is glued to a support 2l which is larger than the blade and which is provided with upturned flanges 28 and 2S protecting the sharp edges of the blade from contact with the enso yelope 2t.

As shown in Figure 6, the support 2 carrying the razor blade It is placed upon the rear surface of the envelope 2d. The support 2l nts snugly into the envelope 2t so that any shifting of the 55 support il? and its blade lo within the envelope 2li is prevented. The blade ill is so located within the envelope 2t that its edges are situated below the outstanding portions 2li of the envelop 2d. Consequently the edges of the blade i@ are protested by the frame-like portion 2d which 'forms air-cushions surrounding the edges of the blade, and the upturned edges 2Q and 29 of the support 2l. Bue to this arrangement, any .contact between the edges o the blade and the paper is 55 effectively prevented so that there is no danger that the razor blade edges will be damaged or dulled prior to use.

Obviousiy, various changes may be made in the construction of the device illustrated in the drawlil ing. For instance, a supplementary piece o cardboard 26 may be glued to the central depressed portion 23 of the envelope 2t to ensure further safety of the blade,

The supplementary piece of cardboard it may 75 f in such case the outstanding portions 2l may be.-

be oi' the same dimensions as the support 21 and eliminated entirely.

Any suitable number of blades carried by individual supports may be inserted into a single envelope 20. 4

Figure 7 shows a support 50 which is provided with upturned hook-shaped portions 5|, 52, 53, and 54 holding the blade l0. The blade may be conveniently removed from the support 50 and placed upon a safety razor without coming in contact with the ngers of the user, by bending the support 50 in the middle.
