Jan. 10, 1956 L. M. APPELDORN DISPOSABLE RAZOR Filed June 4, 1953 IN VENTOR 100 111. @zueldazm ATTORNEYS United States Patent 37 .99. 3? DISPOSABLE RAZOR L M-App ldom, Hun ington, W. Va.

Application June .4, 1953, Serial No. 359,561

2 Claims. 01. 30-41 This invention relates to safety razors, particularly that type which is designed for one use only and is disposable, and may be sold in railroad stations, public washrooms and like places.

While disposable razors are not new, those previously known have not been satisfactory. In attempting to produce a razor which could be made at extremely low cost, most of the desirable characteristics of the permanent type razor have been eliminated.

The primary object of the present invention is to provide a safety razor which embodies most of the features of high grade permanent razors but which, because of its construction, can be manufactured and sold at a sufficiently low price to be disposable after a single use.

A more specific object of the invention is to provide such a safety razor which will be handleless, but of such shape that it may be conveniently held in the hand for shaving.

A further object is the provision of a disposable razor which provides for drainage of waste so that it will not become clogged in use.

Other objects of the invention will become apparent from the following description of one practical embodiment thereof when taken in conjunction with the drawings which accompany, and form a part of, this specification.

In the drawings:

Figure 1 is a perspective View of a disposable safety razor embodying the principles of the present invention;

Figure 2 is an end view of the razor;

Figure 3 is a plan view of the razor;

Figure 4 is a front view with parts broken away to show the blade;

Figure 5 is a vertical section taken on the line 5-5 of Figure 4; and

Figure 6 is a view of a blank which may be folded up to form the razor.

In general, the invention consists of a rectilinear body having one face to receive a razor blade, with means to hold the blade tightly against the face, and means to permit free drainage of waste.

Referring to the drawings in detail, the body 1 serves as both blade holder and gripping element. All of its longitudinal faces are rectilinear in shape, and its ends 2 are shaped as rhomboids having bottom, front and back edges disposed at right angles to one another and its fourth side angularly disposed with respect to the bottom and inclining downwards toward the front. The bottom panl 3 connects the bottom edges of the sides, and the front is closed by a panel 4. The top panel 5 forms a blade rest and, as mentioned, is inclined forwardly with respect to the bottom. The blade rest is cut out along its forward edge to form a slot 6. Slot 6 terminates short of the side edges of the blade rest, and forms a passage to allow lather and cut whiskers to pass into the body 1. Projections 7 at either side of the front edge of the blade rest are turned back to provide seats into which the side portions of the edge of a blade 8 may seat to properly 2,729,887 Patented Jan. 1 956 M AC? align the blade edge with the front edge of the body l for shaving. The blade rest is provided with upstanding bosses 9, one near either side edge, to hold the back edge of the blade spaced from the blade rest for a purpose to be described.

The back of the body is formed with a panel 10. The back is slotted, as at 11, to allow waste which enters the body through slot 6 to flow out. It will be noted that the slots .6 and 11 are at diagonally opposite corners of the body so that there can be no large accumulation within the body. If waste does accumulate, the razor may be placed under a faucet and the water stream will enter one slot and flush out the waste through the other.

When the blade is in place on the blade rest, it is held in the seats formed by the projection 7 and against the bosses 9 by means of a resilient flap 12. Flap 12 is formed of two sections, the section 13 adjacent the back 10 and inclined outwardly from the blade rest, and the section 14 which is a continuation of section 12 but angularly related to it to decline from its line of juncture with sec tion 12 to have its free edge bear upon the rabor blade to hold it firmly upon the blade rest. The free end of the flap contacts the blade along a line intermediate the blade edge and the bosses 9. The flap is sufiiciently resilient to hold the blade rigid while in normal use.

The razor may be made up of separate panels of plastic, sheet metal, or other suitable material with the various panels joined together. The blade may be put in place before the flap is joined to the back, or the blade may be slid in from the side after the body is completely formed.

A very inexpensive manner of forming the body is to fold it up from a blank of the shape shown in Figure 6. In this form also the material may be plastic or metal. By referring to Figure 6 it will be seen that flap 15 having the

sections

16 and 17 is joined to the back 18 along a fold line. The back is provided with a slot 19, one edge of which forms part of the line of fold separating the back and the bottom panel 20. Front panel 21 is joined to the bottom, and the blade rest 22 extends from the front. Slot 24 is cut into the blade rest and projections 23 which are bent to form the blade seats are struck from the front panel 21. Bosses 25 are pressed upwardly from the blade rest. The end panels 26 for completing the box and giving it its cross-sectional form extend outwardly from the side edges of the bottom panel 20. It will be obvious that the razor will have exactly the same form and contain the same features as when constructed of separate panels as previously described.

A razor constructed in the manner disclosed will be extremely simple yet quite sturdy. The blade is held firmly in place and the corners are protected to prevent accidental cutting. The flap not only holds the blade in position but acts as a protective cover leaving only the cutting edge exposed. The edge of the body between the front and blade rest acts as a guard to prevent injury in handling the razor and while shaving. Due to the construction the razor may be sold so inexpensively that it is disposable after one use.

Although in the above specific details of construction have been disclosed, it will be understood. that this is merely by way of example, and that structural details may be changed without departing from the invention as defined in the appended claims.

What is claimed is:

l. A disposable razor comprising a body having a bottom, front, back and side panels and a blade rest substantially closing the top thereof, a resilient flap projecting from said back panel and extending over the major portion of said blade rest and adapted to have its free edge bear upon a razor blade on said blade rest and hold the blade in place upon said blade rest, said blade rest having a longitudinal slot adjacent the juncture of said blade rest and said front panel, and at least one of said other panels having a slot diagonally disposed from said first mentioned slot with respect to said body, whereby waste may enter the body through the slot in said blade rest and flow out through the other said slot.

2. A disposable razor to receive a blade comprising, a body having bottom, front, back and end panels and a blade rest substantially closing the top of said body, said front and back panels being parallel to each other and perpendicular to the bottom and said blade rest declining forwardly toward said bottom, said blade rest having bosses upon which the blade may rest, projections at the sides of the front edge of the blade rest turned back to form seats for the cutting edge of the blade, and a resilient flap joined to the back and having its free edge in pressure contact with said blade between the edge of the 4 blade and the points of contact of said blade with said bosses, said resilient flap extending over the major portion of said blade rest and contacting the blade near its cutting edge, said blade rest having a slot extending longitudinally adjacent the juncture of said blade rest and said front panel, and said back panel having a slot extending longitudinally adjacent the juncture of said back and bottom panels, whereby Waste may enter said body through said slot in the blade rest and flow out through 10 the slot in the back panel.
