Claims4
An apparatus for removing an injector blade held within a razor by clasping members and reinserting it into the razor in an inverted position for further use, which comprises:
- a cartridge for receiving a blade and storing it prior to reinsertion, the cartridge including:
- an elongated razor head aperture for receiving the head of an injector razor;
- a blade slot extending from one end of the razor head aperture to the exterior of the cartridge, the blade slot sized to receive and contain an injector blade;
- an end slot extending from the end of the razor head aperture opposite the blade slot to the exterior of the cartridge, the end slot and blade slot being aligned with one another;
- first means for separating the clasping members and guiding the razor head into the razor head aperture so that a blade within the razor head will be aligned with the slots;
- and
- second means for separating the clasping members and guiding the razor head into the razor head aperture in a second blade-receiving position so that the razor head will be properly aligned to receive a blade from the blade slot;
- and
- a push key for sliding the blade out of the razor and into the blade slot and out of the blade slot and into the razor.
