Safety razor blade equipped with multiple protuberances

When two conventional safety razor double-edged blades are superposed on top of each other, there is no space in between them to pass the shaving residues. The presently invented safety razor double-edged blade is equipped with several spaced protuberances on its surface. When two of these present invented blades are overlapped, there is a space between them to pass the shaving residues to be rinsed away by running water. Therefore two, three or more of them can be superposed on a single razor blade holder to allow the user to experience all the benefits of a multi-blade razor cartridge in a safety razor blade system.

THE BACKGROUND OF THE INVENTION

When two conventional safety razor blades are installed on a single razor blade holder, they lay on top of each other with no space between the two blades to allow the shaving residues to pass and essentially act as one thick blade. The presently invented safety razor blade equipped with multiple protuberances can create a space between two safety razor blades to allow the shaving residues to pass and allow the user to experience all the benefits of a multi-blade razor cartridge in a safety razor blade system.

THE BRIEF DESCRIPTION OF THE INVENTION

When two presently invented safety razor blades equipped with multiple protuberances are overlapped together there is a space in between them because the built-in protuberances act as spacers to create space in between the blades. Therefore two or more of the blades can be stacked together on a single safety razor blade holder in order to achieve the benefits of a multi-blade razor cartridge in a safety razor blade system.

THE DETAILED DESCRIPTION OF THE INVENTION

Referring now in detail to the drawings, number10ofFIGS. 1 and 3is a safety razor blade equipped with multiple protuberances (abbreviated as razor blade10hereafter). Numeral11ofFIGS. 2 and 3is a safety razor blade equipped with multiple protuberances, wherein the protuberances are serial slotted prominences (abbreviated as razor blade11hereafter). Number12ofFIG. 3is a safety razor blade holder stacked with three safety razor blades equipped with multiple protuberances, two of razor blade10and one of razor blade11. Number13ofFIG. 1is thin blade of razor blade10. Thin blade13is as thin as a conventional safety razor double-edged blade. Number14ofFIG. 1is the built-in protuberance (abbreviated as protuberance14hereafter), which is an elongated prominence and preferably made of flexible material. There are preferably four protuberances14, as illustrated inFIG. 1. Each protuberance14is approximate 1/16 inch in height which determines the distance of the space between two razor blades10or two razor blades11, 1/16 inch in width and 4/16 inch in length. Number15ofFIGS. 1 and 2is the central cut out of razor blade10and razor blade11. The central cut out15is the same as that of a conventional safety razor double-edged blade. Number16ofFIGS. 1 and 2is the length of razor blade10and razor blade11. Number17ofFIGS. 1 and 2is the width of razor blade10and razor blade11. Number18ofFIG. 2is the thin blade of razor blade11. Thin blade18is as thin as a conventional safety razor double-edged blade. Number19ofFIG. 2is the built-in protuberance (abbreviated as protuberance19), which is serial slotted prominences. There are preferably four protuberances19, as illustrated inFIG. 2. Each protuberance19is approximately 1/16 inch height, 1/16 inch in width and 4/16 inch long in length. Number20ofFIG. 1is the sharp edge of razor blade10. The protuberance14ofFIG. 1is built transversely at the sharp edge20and spaced at a distance from other protuberances14. Number21ofFIG. 2is the sharp edge of razor blade11. The protuberance19ofFIG. 2is built transversely at the sharp edge21and spaced at a distance from other protuberances19. Number22ofFIG. 3is a razor blade holder of safety razor blade. Number23ofFIG. 3is the cover member of razor blade holder22. One of the razor blade11and two of the razor blade10are installed on the razor blade holder22. The length16and the width17of razor blade10and razor blade11are the same as those of a conventional razor double-edged blade. The width17of razor blade10and razor blade11can be varied with gradual narrowing. Therefore, there are wider razor blade10and razor blade11. The narrower razor blade should be superposed on the top of the wider one for easier shaving. In this case, the cover member23of razor blade holder22should have the same gradual narrowing width corresponding to the width17of razor blade10and11.
