6 Claims. (CI. 30-47) This invention relates to safety razors and more particularly to disposable razors suitable for sale at low cost.

The present invention is designed to meet a need for an inexpensive safety razor. A need for such a razor often arises with travelers, campers and others when remote from readily accessible shaving supplies. In such circumstances it is desirable to have an inexpensive razor that can be disposed of after a minimum number of shaves. Such a razor must necessarily be uncomplicated and possess a minimum number of parts. At the same time the razor must be sufficiently rigid and durable to withstand handling when it is used.

A razor meeting these qualifications can be made in sheet-like form ready for use after making a few simple folds along score lines embodied therein. In such sheetlike form very little space is occupied during storage. Thus, it is particularly convenient for carrying in luggage for emergency use. In addition, the sheet-like form is adapted for dispensing the razor in ordinary coin machines located in washrooms, in trains, transportation depots, and the like. Finally, the sheet-like form of the razor makes it readily adaptable for use as a medium for advertising or as a gift novelty.

Accordingly, the primary object of this invention is to provide an inexpensive safety razor for use in emergencies which has a compact design.

Another object of this invention is to provide a safety razor that is so inexpensive that it can be discarded after a single use.

Finally, it is an object of the invention to provide a disposable razor in blank form including a blade, which may be folded to a usable shape and which satisfies the foregoing objectives and desiderata.

These and other objects are accomplished by the parts, elements, devices, constructions, arrangements, combinations and sub-combinations comprising the present invention, the nature of which is set forth in the folding general statement, a preferred embodiment of which-illustrative of the best mode in which applicant has contemplated applying the principles-is set forth in the following description and illustrated in the accompanying drawing, and which is particularly and distinctly pointed out and set forth in the appended cliams forming a part hereof.

In general terms, the disposable safety razor constituting the present invention may be stated as including a sheet-like member of light metal or plastic to which a razor blade is attached, and which is provided with transverse score lines on which the member is folded for forming a safety razor head, and which is provided with generally longitudinally disposed score lines on which the member is folded for forming a handle portion for the razor. The member need not be folded until the razor is to be used.

Referring to the accompanying drawing, which is illustrative of a preferred embodiment of the invention, by way of example, and in which similar numerals refer to similar parts throughout:

Fig. 6 is an enlarged plan view of a sheet-like blank from which the safety razor may be formed and showing gtlertagn of the score lines and apertures embodied in the As shown in Fig. 1, a safety razor is generally indicated at 1 in a form ready for use after having been folded along certain score lines provided in a manner described hereinbelow.

A sheet-like member 2 is shown in Fig. 6. It is a blank or flat piece of sheet material of either plastic or metal sheet or foil. The preferred material is aluminum sheet of .008" to .010 thickness. But, an aluminum sheet having .005" thickness may be used if rigidized. However, the member 2 may be composed of steel sheet of .001" to .002" thickness if the steel is of proper analysis to permit bending or folding in a manner described hereinbelow. Whatever may be the thickness of the material, it must be thick enough to provide rigidity for shaving yet thin enough for relatively easy folding.

The member 2 consists of a tapered portion 3, a razor portion 4, and a handle portion 5. As shown in Fig. 6, the member 2 is an elongated rectangular member and the razor portion 4 is divided from the tapered portion 3 and the handle portion 5 by score lines 6 and 7, respectively, extending transversely of the longitudinal axis of the member.

The tapered portion 3, having converging sides extending from the longitudinal edges of the member 2, is provided with a tongue 8 at the zone of convergence. For the purpose of facilitating the folding of the blank it is preferred that the converging sides be concavely arcuate. Thus, clearance is provided for the sides of the handle extending from the score line 7 during the final folding of the handle (Fig. l).

The razor portion 4 is provided with a transverse score line 9 (Fig. 6) near the score line 6. Along the score line 9 is disposed a plurality of apertures 10, the centers of which are aligned with said score line. A razor blade 11 is attached to the razor portion 4 so that cutting edge 12 of the razor blade overlies the apertures 10 (Fig. 4) and particularly that portion of the apertures disposed between the score lines 6 and 9. The razor blade 11 is secured to the member 2 by means of a water-proof adhesive, but other means of attachment may be used. For example, if the member 2 is composed of steel sheet, the razor blade may be attached thereto by spot welding.

The handle portion 5 constitutes the greater portion of the length of the member 2. It includes a pair of spaced score lines 13 (Fig. 6) extending longitudinally over a greater portion of the handle 5 from the end of the handle remote from the razor portion 4 to points 13a spaced from the score line 7. In addition, the score lines 13 extend from the points 13a to the opposite side edges by divergent arcs 14. The score lines 13 thereby divide the handle into longitudinal elements, including an intermediate element 15 between score lines 13, and side elements 16 and 17 on either side thereof. Finally, the handle portion 5 is porvided with a tongue-receiving slot 18 disposed between the score lines 13 near the points 13a.

The first folding operation in the forming of the razor 1 from the sheet member 2 is on score lines 6, 7 and 9, as shown in Fig. 3. At the same time the tongue 8 is inserted into the tongue-receiving slot 18 and folded back over the intermediate handle element 15. By these operations a head portion 19 is made whereby the cutting edge 12 of the razor blade 11 is disposed in a cutting position overlying the leading edge formed by the fold about the score line 9. The segments of the score line 9 between the apertures 10 provide protection against cutting by the cutting edge 12 in a manner similar to guards on the conventional safety razor. In addition, that segment of the razor portion 4 between the score lines 6 and 9 serves as a reinforcement for the structure adjacent the razor and the apertures 10. Likewise, that portion of the handle 5 between the score line 7 and the slot 18 is arched, when the tongue is secured in the slot, thereby providing reinforcement for the razor head 19. Y

The final forming operation of the razor 1 consists of folding the handle 5 about the score lines 13 and the divergent arcs 14 so that a handle is formed having a triangular transverse cross-section as shown in Fig. 5. The portions of the side elements .16 and 17 adjacent the divergent arcs '14 provide reinforcement between the head portion and the handle by the folds about the divergent arcs 14 which extend longitudinally as well as transversely of .the sheet member 2. More over, said portions of the side elements 16 and 17, when folded, are at substantially right angles with the aforementioned arched portion of the handle 5 between the score line 7 and the slot 18 (Fig. 4), thereby combining to further reinforce the razor head This configuration results from the concavely arcuate sides of the tapered portion 3'WhlCh give clearance for the proper angle of the upper ends of the side elements 16 and 17. In short, the particular combination of said arched portion of the handle 5, together with the folding of the side elements 16 and 17 along the divergent arcs 14 at substantially right angles to the arched portion, establishes maximum reinforcement for the razor head 19, which reinforcement is strengthened by the continuation of said parts as portions of the handle. The reinforcing folds extend transversely as well as longitudinally providing a more rigid unit.

Additional reinforcement of the various portions of the safety razor 1 may be provided by the use of light score lines on the several surfaces. Accordingly, the surface of the tapered portion 3 is provided with a plurality of light score lines 20 extending longitudinally thereof. Likewise, the intermediate element 15 of the handle is provided with longitudinal light score lines 21 as well as transverse light score lines 22. Also, the side elements 16 and 17 of the handle are provided with transverse light score lines 23. Finally, that portion of the handle between the divergent arcs 14 is provided with light score lines 24. Hence, the light score lines 2024 provide rigidizing or reinforcing means for the elements of the razor member 2 and permit the use of lighter gauge sheet material, such as metal foil, than would be otherwise usable.
