The member carries a plurality of cutting means which are successively indexed at the slot for shaving.

1 Claim, 2 Drawing Figures DISPOSABLE SAFETY ROTARY RAZOR SUMMARY OF THE INVENTION This invention relates to a new and completely new concept in a safety razor. This new, one unit, inexpensive, disposable rotary razor provides a super floating action shave. It has fewer parts than any shaver on the market today. In addition, it also has less parts in the complete unit than can be found in just a blade dispenser itself. This razor is easy to use and, because of its principles, gives a really clean, close and comfortable shave. Because of its unique design, this invention lends itself well to practical manufacturing.

This safety rotary razor is made inexpensively, is of one unit, and can be thrown away after a plurality of shaves by the user. It can be made of bright colored plastic. It employs a plurality of blades, for example, six blades. The blades are adhesed to an hexagon-shaped plastic inner spool.

This one-unit spool holder and handle are made of an inexpensive brightly colored plastic and can have a shim of semi-flexible teflon plastic material which is cylindrically shaped and adapted to be fitted within said outer spool holder and adhesed to the inner surface of said outer holder in a manner to serve as a blade shield and blade wiper reed. This dual function is accomplished through the provision of an elongated slot extending lengthwise of said cylindrically shaped semiflexible shim, the edges of said slot being turned inwardly along the length of said slot to form blade wiper reeds which are arranged to press inwardly and contact the blades to wipe said blades as they move out of shaving position.

Two spool plug ends with a red markeron them can fall in line with the last blade which also has a thin red line on it to remind the user that he is on his last blade. This will give him ample time to buy and replace the razor in use.

To change the blade, all one has to do is to hold the spool, plug end between his thumb and first finger (left hand) (cutting edge up), and move the handle down until a clicking sound caused by the passing of the new blade as it is rotated past the inwardly pressing blade wiper reed which is in close contact with said new blade as it is rotated into operative position and a new blade comes into view. It is again ready for use.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings: FIG. 1 is an exploded view of my invention; and FIG. 2 is a side view of my invention in use.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIG. 1, a hollow elongated plastic semi rigid sleeve 10, open at both ends, has an axially extending slot 12. A plastic handle 30 is secured to the center of the sleeve and extends at right angles thereto. An elongated hexagon shaped plastic spool 14 has an axial bore 16. A separate stainless steel blade 18 is secured to each of the axially extending faces with a cutting edge which extends thereout. A thin flexible teflon sleeve 20 with an axial slot 22 having inwardly turned blade wiper reed edges is disposed axially within the sleeve 10 wi th slot 22 aligzned with slot 12. Spool 14 is disposed within the sleeve 0 so that the cutting edge of a blade extends outwardly and downwardly from the aligned slots 12 and 22 for use in shaving. Control knobs 24 have axially extending pins 26 which engage opposite ends of the spool. These knobs have aligned markers 28 which will point to the last blade in use after all other blades have been successively indexed at the slots for use whereby the user knows he should throw the entire unit out and obtain a replacement.

While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.

I claim:

1. A disposable safety rotary rotary razor comprising:

A. an elongated semi-rigid outer cylindrical sleeve open at both ends and having an open slot extending axially throughout the length of said sleeve,

B. a handle fixed to the midpoint of said sleeve and extending at right angle thereto,

C. an elongated hexagonal spool disposed within said sleeve and manually rotatable therein on an axis parallel to the wall of said sleeve, said spool having in cross section the shape of a hexagon with each of its six flat faces extending the entire length of said spool,

D. six separate stainless steel shaving blades, each of said blades being fixed to one of the flat faces of said elongated spool extending throughout the length thereof and each of said shaving blades having a cutting edge protruding outwardly from said,

spool extending beyond the flat faces to which each blade is fixed,

E. each of said six blades being rotatable with said spool and means to index each of said blades opposite the open slot of said elongated semiqigid outer cylindrical sleeve and the cutting edge of each blade adapted to protrude outwardly through said slot,

hexagonal spool and a control knob for each end of said spool, each control knob having a pin adapted to enter said bore in a manner to fix said control knobs to opposite ends of said spool and manually rotate said spool,

G. a semi-flexible cylindrical shaped shim adapted to be fitted within said semi-riged outer cylindrical sleeve and to surround said elongated hexagonal spool which is disposed within said sleeve whereby both said shim and said spool are disposed within said semi-rigid outer cylinder, said shim being adhesed to the inner wall of said outer cylinder and said spool being rotatable within both said shim and said outer cylinder,

II. an open slot formed in said cylindrically shaped semi-flexible shim said slot extending parallel to the open slot of the semi-rigid outer cylindrical sleeve in which it is disposed and to which it is adhesed said slot having inwardly turned edges along the length of the slot to form blade wiper reeds and arranged to press inwardly against and contact the blades as they are rotated and moved out of shaving position.

. an axially extending bore formed in said elongated

Claims
