Patented Mar. 10, 1953 RAZOR BLADE MAGAZINE Max Kleinmann and Jack H. Kleinmann, Brooklyn, N. Y.

Application January 24, 1949, Serial No. 72,502

5 Claims. (C1. 30-40) This invention relates generally to the field of razor blade packaging and more particularly to improvements in razor blade magazines.

It is among the objects of the present invention to provide razor blade magazine constructions which are easily loaded, particularly in view of the fact that the blades are placed within the magazine in an alined stacked relation, staggered arrangements being avoided.

Another object herein lies in the provision of structure of the class described in which the blades are consecutively and singly deposited upon a platform from which they may be easily and conveniently positioned upon the razor with which the blade is to be used.

A feature of the invention lies in the fact that the present construction with minor alterations may be utilized in connection with razor blades of various types although for the purpose of example, the present invention has been illustrated in connection with double edged razor blades having a central orifice.

Another object herein lies in the provision of razor blade magazines in which only one blade is fed out at a time and jamming is avoided. In view of the fact that in accordance with present construction the blade is positively guided at all times prior to its actual positioning upon the razor, the blades cannot twist and their cutting edges are protected against accidental contact. The prevention of accidental contact of the cutting edges not only keeps them sharp but also prevents the user from cutting himself.

Another object herein lies in the provision of structure whereby the blade is fully supported until actually removed so that it cannot accidentally fall on the floor.

The present devices are compact and easily operated, because one positive stroke feeds one blade.

As illustrated in certain of the following em- 'bodiments, the last fed blade may be completely :separate from the stack so that it may be picked up by old style razors in which the entire blade must be engaged by the head at one time rather than by the hooking arrangements on some of the newer models of razors.

Another feature of the present invention lies in the fact that the blades in the stack, prior to actual use, may be kept fully lubricated and are protected from outside contamination.

These objects and other incidental ends and advantages Will more fully appear in the progress of this disclosure and be pointed out in the appended claims.

Turning now to the first embodiment of the invention illustrated in Figures 1 to 6 inclusive, the razor blade magazine generally indicated by reference character l0 comprises broadly a casing l2 and a blade container l4. As'will be obvious to those skilled in the art to which the present invention relates, these parts may be made of various materials such as metal, card board, or artificial resin. When made of metal, the parts may be stamped and formed or die cast. When formed of card board they may be blanked, folded and the joints secured by suitable adhesives. Because of the pleasing appearance, sanitary condition and low cost manufacture which synthetic resins afford I prefer to mould these parts in suitable dies from such synthetic resins, frequently referred to as plastics. Many suitable plastics are known including cellulose acetate, methyl methacrylate, polystyrene, and the like.

The blade container I4 is generally of boxlike configuration, having a bottom opening I6. The container l4 includes a top wall I8, a front wall 20, a rear wall 22, a left side wall 24, and a right side wall 25. The top wall I8 is provided with a depression 28 which is adapted to receive one of the users fingers, preferably the thumb for manipulation of the device. Disposed at the four corners of the container I4 are a plurality of blade aligning guides 33 to 33 inclusive. The guides 30-33, serve to properly position the blades generally indicated by reference character 34 while they are in the stack 35 as will more fully appear. Disposed between the topmost blade 36 in the stack 35 and the inner surface of the topwall I8, is a resilient member 38. This is preferably composed of sponge rubber, although other materials such as felt, cotton, wool, or plastic or metallic springs may be used. The resilient member 38 is not intended to urge the blades out of the blade container I4, but rather to keep them parallel with each other and with the bottom wall, as will more fully appear. The guides 30-33 not only keep the blades 34 in alignment, but they prevent the cutting edges from contacting the inner surfaces of the

side walls

24 and 26.

The casing I2 includes a top wall 49, a bottom wall 42, a front wall 44, a rear wall 46, a left side wall 48, and a right side wall 50. The top wall has a rearwardly extending indentation which extends to the rear a distance sufficient to permit convenient access to the depression 28 and is also preferably slightly wider than the depression 28, for the same purpose. The forward portion of the top wall 4!! includes left and right

ledge portions

52 and 54 which extend inwardly toward each other on opposite sides of the opening 55 sumciently to prevent the blade container from coming up through the opening 56.

The bottom wall 42 at the forward portion thereof has a blade supporting platform 58. The platform 53 is downwardly depressed in the bottom wall 42 a distance substantially equal to the thickness of a single razor blade and is of substantially the same outline except that the

ridges

60 and 62 are spaced apart from each other a distance greater than the distance between the

cutting edges

34 and 66 of a blade 91 when it is located upon the blade supporting platform. Bordering the blade supporting platform 58, and preferably at the four corners thereof, are the front blade retaining guides 68 and ill and the rear blade feeding guides I2 and 74. The front blade retaining guides 68 and II! are provided with rearwardly extending

ramp portions

16 and 8. The bottom wall 42 at the forward portion thereof, and extending rearwardly from the front edge 80 thereof, is provided with a razor receiving indentation 82.

Operation of first embodiment The blade container I4 is normally located in the position in which it is shown in Figures 2 and 3, and it tends to remain there because of gravity and friction. When it is desired to remove the lowermost blade from the stack 35, the device I 0 may be held in the palm of one hand, and preferably with the thumb, the blade container I4 is moved forwardly, or to the left, as seen in Figures 2 and 3 of the accompanying drawings, whereupon the lowermost blade in the stack, will be deposited, principally by gravity, upon the blade supporting platform 58. In this position of the blade container, the forward wall 28 may abut against the inner surface of the front wall 44. The blade then deposited upon the blade supporting platform 58, said blade being indicated by reference character 61, is horizontally disposed between the guides I2, I4, I6, 18. Next the blade container I4 is returned to its original position, the guides 12 and I4 acting to prevent the blade 61 from returning with the stack 35.

The blade 61 is now in full view of the user, but he is prevented from manually touching the

cutting edges

64 and 66 in such a direction as would permit him to harm himself, or to damage said cutting edges. The blade 6'! may now be removed, from the magazine I0, by the user bringing a suitable razor (not shown) upwardly and partially through the indentation 82 so that the usual projections, or the like, on the razor may engage the slot 84, whereupon the blade 6'! may be brought forwardly and outwardly through the opening 86 below the front wall 44. The easy movement of the blade 61 outwardly of the magazine I0 is facilitated by its easy sliding action over the ramps I6 and I8.

Turning now to the second embodiment of the invention illustrated in Figures 7 to 12, inclusive, for the purpose of avoiding needless repetition, certain of the parts corresponding to the first embodiment are given the same reference characters, with the addition of a prefix l.

The second embodiment differs from the first embodiment, principally in the relatively shortened length of the casing H2, and the provision of an additional ramp portion I". Also, in this form, the indentation I5I is longer, so that the depression I58 is located closer to the rear wall I22.

When a blade I6! is located upon the blade supporting platform I58, the forward portion of the ramp portion I'I'I engages the central slot I84 and assists in properly aligning it, while the forward edge I15, assists the guides H2 and I14, during the return passage of the blade container H4 in a rearward direction.

In removing a blade, such as the blade IG'I, from the blade supporting platformv I58, the razor (not shown) may engage parts of the exposed portion of the blade to hook and pull it off of the blade supporting platform I58.

In the alternate form of the second embodiment shown in Figure 13 the front wall 220, and the rear wall 222 of the blade container 2I4 are angularly disposed so as to slope forwardly in a downward direction. A central blade aligning guide 229 extends downwardly from the under surface under the top Wall 2 I8 and extends downwardly through the aligned slots in the stack 235.

The front wall 244 and the rear wall 245 of the casing ZIZ are parallel to the

walls

220 and 222 of the blade container.

Certain of the other parts of the form showing Figure 13 have reference characters corresponding to the first embodiment with the addition of a prefix 2.

By virtue of the stepped arrangement of the stack 235, their vertical disalignment further assists in preventing the deposition of more than the lowermost blade in the stack upon the blade supporting platform 258.

It may thus be seen that we have disclosed a novel and useful razor blade magazine construction which in the several illustrated embodiments thereof provide for secure, sanitary, and protected maintenance of the razor blades in the magazine and for easy and convenient manipulation and use.

The blades even after having been deposited upon the blade supporting platform, are protected against damage to themselves and to the user. By virtue of the disclosed structure, jamming is avoided, and the blades are fed from the stack in a consecutive manner by positive action.

Because the blades are urged into position upon the blade supporting platform when it is in juxtaposition with the blade container, by gravity, the disadvantages and additional expense of springs or spring actions are avoided.

The present invention avoids the use of skill by the user because of any normal range of digital pressure upon the blade container, because this pressure is not communicated to the blades in the blade container. Thus their feeding is only the result of the reciprocation of the blade container. This may be contrasted with prior art devices in which manual pressure against the blades and against a spring afiects the operation, so that too much or too little pressure causes jamming, misfeeding or failure to feed.

We wish it to be understood that we do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
