Abstract: A one-piece disposable razor having a blade edge protector molded integrally with the razor operable to latch releasably to the razor.

Abstract: A flexible razor blade cartridge having an expansible cap plus a blade support composed of a plurality of contiguous sinews or ribbons of flexible plastic material defining a sinuous, convoluted, cage-like structure including an integral segmental flexible guard bar and means for releasably securing the cartridge to a handle.

Abstract: A socket device for making a pivotal connection between a single or multiple blade cartridge and a support where a connection between the socket and the support is accomplished by interlocking arcuate flanges and a connection between the socket and a cartridge is formed by cooperation between a channel and a track.

Abstract: A replaceable blade cartridge shaving system having an elongate handle with a coupling head formed at its terminal end. The coupling head is arrayed transversely of the handle axis and has two elongate substantially parallel coupling flanges formed thereon. The flanges extend transversely of the head and perpendicular thereto. Located between the flanges and extending a predetermined distance from the terminal end of the handle above a plane containing the flanges is a protuberance member. The cartridge has complementary grooves formed along its base for slidable engagement with the handle flanges and a recess is formed between the grooves having sufficient clearance as to allow the protuberance member to fit therein. Attempted use of the handle with other than a cartridge having such recess produces interference between the handle and the cartridge, thereby preventing slidable engagement therebetween.

Abstract: A dispenser having a plurality of row-arrayed compartments each for releasably retaining a razor blade cartridge therewithin. The opposite ends of the compartments are respectively formed by a partition wall and yieldable, free-standing retention means positioned such that the end of one compartment is not in common with the opposite end of the next compartment, thereby making the compartments independent of one another to minimize the cumulative effects of oversize cartridge tolerances. The free-standing fingers also reduce the force required to manually load cartridges into the dispenser during assembly.
