DISPOSABLE COMBINATION SAFETY-RAZOR AND BLADE MAGAZINE Filed Dec. 30, 1960 INVENTOR.

United States Patent 3,137,940 DISPOSABLE COMBINATION SAFETY-RAZOR AND BLADE MAGAZINE Alfred Curci, 183 London Drive, Hamden 10, Conn. Filed Dec. 30, 1960, Ser. No. 79,811 1 Claim. (CI. 30-40) This invention relates to improvements in safety razors. The main object is to provide a blade magazine comprising a complete shaving device having a plurality of blades arranged in predetermined shaving alignment with respect to corresponding razor blade guards. The magazine, which may be manufactured at a moderate cost, serves a double purpose; it is an item of blade packing ready for distribution, and in addition, provides a complete safety razor ready for use which may be discarded by the user when the magazine has served its intended purpose.

In the conventional type safety razors the common practice is to manufacture and sell the blades and blade holders as separate items. The blade is fed into the razor manually or removed therefrom placing the user in danger of cutting the fingers; or inadvertently the blade may be inserted in the holder improperly aligned which often results in a minor but painful out before the misalignment is rectified. Another serious disadvantage to these previous devices is that a discarded blade may be left where a child picking it up would be in danger of injury. A further disadvantage is that should the blade holder be dropped on a hard surface a misalignment may occur that entails replacement of the costly blade holder. These and other disadvantages are overcome in the present invention, the solution of which comprises important objects of the invention.

In the drawings:

FIG. 1 is a perspective view of the invention with a part in section.

FIG. 2 is a fragmentary section taken substantially on line 22 of FIG. 1.

FIG. 3 is a modification showing in cross section a blade capped with a metallic guard.

The combination safety razor and blade magazine herein shown, comprises a hollow frame indicated generally at 1 having a plurality of safety guards 2 (in this case twelve), a corresponding number of blades 3 disposed in a paddle-wheel configuration. The blades 3 are similarly oriented in any predetermined shaving alignment relative to the corresponding safety-guards 2. This arrangement is clearly seen in FIGS. 1 and 2 of the drawlngs.

Fixedly secured between and substantially at the peripheral edges of identical circular end panels 4 and 5 are a plurality of safety guards 2. Preferably, the guards 2 and end panels 4 and 5 are molded from a suitable synthetic resin. Said guards 2 are fixed longitudinally (in this case by cementing) between said end panels 4 and 5 in a spaced relation to each other. The said guards 2 are substantially round in cross-section, but may be contoured in any suitable fashion. It is to be understood, that as a general thing the guards 2 will be molded as an integral part of the end panels 4 and 5, and if desired, the guards may be provided with segmentally annular grooves or serrations (not shown) to form a comb-like safety guard common to safety razors. Blades 3 may be fixedly secured on blade magazine 1 by any suitable means to provide the most efiicient shaving alignment of blade 3 with respect to guards 2. In this case, as seen in FIGS. 1 and 2 of the drawings, guards 2 are provided with longitudinal slots 9 disposed for a tenaciously gripping reception of blades 3.

- If desired, the structure described and shown herein may be fabricated from metal, in which case the noncutting edges of blades 3 may be fixedly secured to metallic covers or guards 2 such as shown in FIG. 3 of the drawings. The opposite ends of said metallic guards 2 are provided with ears (not shown) which register and interlock by staking or other suitable means with corresponding perforations (not shown) in end panels 4 and 5. It is to be understood, that the magazine 1 may be formed of a suitable sheet metal to provide a tubular or cylindrical member having a plurality of integral spaced guards 2 with suitable means for securing blades 3 in alignment relative to said guards (notshown).

Since it is desirable for the convenience of the user to be informed which blade is in use, the outer face of the end panel 4 and 5 may be marked numerically to indicate which blade is in current use (not shown), or the cut ting edge of blades 3 may be coated with a suitable synthetic resin that is easily peeled off to expose the blade 3 for use (not shown) thereby providing both blade protection and indicia.

The safety razor 1 as described to this point may be used for shaving. The handle member commonly associated with safety razors is not required or essential, in fact, superior control of the razor is possible without the handle member. The user simply holds the opposite ends of the blade magazine 1 between the thumb and forefinger and shaves in the customary manner. However, in the drawings, it will be noted that the razor 1 is provided with a cover 10 to which a detachable handle member 11 (shown in dotted lines) may be threadably attached if desired (threads not shown).

The cover member 10 just previously mentioned, is preferably molded from a suitable synthetic resin being substantially cylindrical having a cut-away longitudinal section 12 whereby said cover 10 is substantially C- shaped in cross section and somewhat resilient. The cover 10 is formed slightly smaller in diameter than end panels 4 and 5 so that said cover 10 is expanded or sprung slightly outwardly to insert the magazine 1 within cover 10 thereby providing the magazine with a slight frictional resistance to free rotational movement within said cover 10. The magazine may be readily slid in and out of cover 10 for cleaning purposes. Cover 10 is further provided with detents 14 arranged for successive registration with a plurality of detent notches 15 formed on pcripheral surface of end panels 4 and 5, said

detents

14 and 15 being disposed to frictionally restrain cover 10 in any one of a plurality of predetermined positions until such time cover 10 is moved manually to expose a successive blade 3. Preferably, as shown in the illustrated embodiment, the cut-away section 12 of cover 10 is of such dimensions that two cutting edges of blades 3 are exposed for shaving. It has been found that using two blades 3 simultaneously results in maximum shaving efficiency, and to this end, while shaving, the user rocks the razor slightly about its longitudinal axis with each reciprocal stroke.

The handle member 11, when provided, is threadably attached (threads not shown) to boss 16 molded integrally with said cover 10 (handle member 11 and boss 16 are shown in dotted lines). When packaged for distribution or when not in use, handle member 11 may be stored conveniently within central hollow portion 17 of magazine 1.

The invention as applied to a single embodiment has been shown and described, but it will be understood, that various changes in the form and details of the device illustrated may be made by those skilled in the art without departing from the spirit of the invention.

What is claimed is:

A shaving device comprising a substantially cylindrical hollow frame, including a pair of similar circular end panels, a plurality of spaced longitudinal members secured between and substantially at the peripheral edges of said end panels, means to secure on said frame a plurality of blades in a laterally spaced relationship to said 4 spaced longitudinal members, a cover member disposed to resiliently and revolvably embrace said cylindrical frame, said cover member being manually revolvable relative to said frame is provided with a cut away longitudinal section to successively expose for use one or more blades.
