W. C. KOVAL PAPERBOOK RAZOR Sept. 6, 1955 Filed July 6, 1954 IN V EN TOR.
United States Patent '0 PAPERBOOK RAZOR Walter C. Koval, Los Angeles, Calif.
Application July 6, 1954, Serial No. 441,197
8 Claims. (Cl. 30-47) This invention relates to a paperbook razor, and more specifically, to a razor of the cheap disposable type. This type of razor is especially useful to people who are travelling and for some reasondo not carry a shaving kit. They find themselves on a Sunday or holiday in a place where the barber shops are closed and naturally do not wish to appear in public unshaved.
Persons caught in this situation do not ordinarily wish to pay the price of a standard razor since they already have one, but are willing to pay a small amount for an inexpensive disposable razor that will be satisfactory for one or more shaves.
Applicant has invented such a razor that, when folded, assumes the appearance of a conventional match book and when unfolded will assume the proportions of a standard razor.
This improved razor may be purchased from stores and vending machines at any hour and may be conveniently carried in the pocket at all times for emergency use and subsequent disposal.
The primary object of this invention is to provide a paperbook, disposable razor for emergency use that is normally folded to the proportions of a match book with room for advertizing matter if desired, and one that may readily be unfolded to the size of a standard safety razor.
Another object is to provide a disposable razor that is furnished with a normal blade and a small supply of soap so that the article may be used wherever water is available.
A further object is to provide a disposable razor that is simple and practical in design and one that is made of cheap yet durable material.
Other objects and advantages will become apparent from the following description.
In the drawings,
Fig. 1 is a perspective view of the razor in its unfolded, ready to use, form. 2
Fig. 2 is an exploded, perspective view of the component parts.
Fig. 3 is a top plan, with the blade partly broken away, of the razor.
Fig. 4 is a vertical, sectional view taken on the line 4-4 of Fig. 3.
Fig. 5 is a vertical, sectional view taken on the line 5-5 of Fig. 3.
Fig. 6 is a horizontal, sectional view taken on the line 6-6 of Fig. 1.
Fig. 7 is a perspective view of the razor in its folded position.
The numeral 10 designates the razor in general, the same comprising a blank which provides a housing 12 made of a single sheet of sturdy, water-repellent paper, cardboard or the like.
The inside surface of housing 12 is divided into vertical panels, 14, 15, 16, 17 and 18 by score lines 14a, 15a, 16a and 17a. Intermediate the top and bottom edges of the housing 12 are formed horizontal score lines 18 and 19. All of the aforesaid score lines are provided to facilitiate assembly of the component parts of the razor and their subsequent folding in to the positions shown in Figs. 1 and 7.
The panel 16 is provided, from score line 19 to the bottom of housing 12, see Fig. 5, with a coating of soap 20 for use in lathering the face of the user. The soap 20 is afiixed to the housing 12 by any suitable adhesive.
The razor proper, see Fig. 2, comprises a T-shaped mounting 21, having a depending shank 22, the mounting 21 being fixed to panel 16 from score line 18, to the top edge of housing 12, by any suitable adhesive. The mounting 21 may be made of plastic, metal or the like.
The mounting 21 is provided centrally with a short, upright extension 24, having at one side a cam face 25. The lateral arm 26 of the mounting 21 is provided at its ends with bearings 27.
The blade holder 28 is provided with studs'or pintles 30 for mounting in bearings 27, and a lug 31 to engage cam face 25. The holder 28 is cut out at 32 to ac commodate the extension 24.
The blade holder 28 is extended laterally as at 34,-
to provide a rectangular base 35 for the blade 36, the same being of thin rectangular formation and having a slot 38.
The base 35 is centrally provided with an upstand ing rectangular lug 39, proportioned to loosely fit the slot 38. Suitably adhesive may be used to aflix the lug I 39 in slot 38 of blade 36.
The base 35 is set back at 40, the thickness of blade 36 leaving shoulders 41 at each end to support the blade. The set back 40 serves to provide a cavity 42 under the major portion of the blade 36 to prevent clogging by soap and hair.
The rear edge of blade 36 abuts the shoulders 40a of set back 40, the said shoulders merging centrally and rearwardly of lug 39 into a reduced relief area 44. As shown in Fig. 4, the base 35 has a rounded front edge 45 substantially co-extensive with the cutting edge 45 of blade 36, said edge being adapted to contact the face of the user.
The base 35, between rounded edge 46 and shoulders 40a and on opposite sides of lug 39, is provided with slots 47 and 48 adapted to co-act with cavity 42 to prevent clogging of the razor.
Fig. 2 indicates the order of assembly. The blade holder 28 is placed so that pintles 30 are mounted in bearings 27 and lug 31 is snapped under cam face 25 to maintain the blade holder in the proper angular position for shaving as shown in Fig. l.
The panels 14 and 18 are coated with a special adhesive so that along with panels 15 and 17, they may be bent back to form the reinforced triangular handle 50 shown in Fig. 6. The panels 15 and 17 are bent away from the razor for approximately and the panels 14 and 18 are then folded 120 so that they confront each other, with the edges 14b and 18b abutting panel 16. The special adhesive causes panels 14 and 18 to adhere to each other, the same forming a central stifiening rib 49 for the triangular handle 50.
In Fig. 7 is shown the folded, disposable razor. The blade holder 28 is folded, as shown by dotted lines in Fig. 4, to a position parallel to the inner face of housing 12. At this time the lug 31 snaps up past cam face 25 to release blade holder 28.
From the foregoing, it is apparent that I have inventer a disposable razor made of cheap material that is ingeniously designed to provide a match book formation in folded condition. The razor will give the shaving service of a standard razor for a limited time, and in its collapsed position, can readily be carried in Patented Sept. 6, 1955 the pocket so as to be ready for an emergency, since it takes up no more room than a match book.
I hereby reserve the right to make numerous changes in the size, shape and arrangement of the parts Without departing from the spirit of the invention and the scope of the appended claims.
l. A paperbook razor comprising a housing having longitudinal and lateral score lines dividing said housing into central, intermediate and end panels and upper and lower portions; a mounting on the upper central panel having bearings; and a blade holder having pintles adapted to be freely mounted in said bearings.
2. A paperbook razor comprising a housing having longitudinal and lateral score lines dividing said housing into central, intermediate and end panels and upper and lower portions; a mounting on the upper central panel having bearings and having a cam face; and a blade holder having pintles adapted to be freely mounted in said bearings and having a lug adapted to engage the cam face.
3. A device of the character described in claim 2, wherein said blade holder has a second lug; and a blade having a slot adapted to receive the said second lug.
4. A paperbook razor comprising a housing having longitudinal and lateral score lines dividing said housing into central, intermediate and end panels and upper and lower portions; a mounting on the upper central panel, said mounting having bearings; a blade holder having pintles adapted to be freely mounted in said bearings and having supports at each end; and a blade adapted to rest upon the said supports, the said blade holder having a set-back under the blade between the said supports.
