Razor handle

A shaving razor handle comprising

• an elongated hand gripping structure, and
• a cartridge support structure extending from an end of said hand gripping structure,
• said cartridge support structure having outer side surfaces that mate with inwardly directed surfaces of a recess on a cartridge and an end surface with an opening, and
• a spring-biased plunger that has a cam follower surface, is retained in said cartridge support structure and extends through said opening of said cartridge support structure,
• wherein said spring-biased plunger is guided by a slot in said cartridge support structure,
• further comprising an ejector pushed by a snap fit elector button,
• wherein said plunger and said ejector are biased in opposite directions by a spring.

A shaving razor handle comprising

• an elongated hand gripping structure, and
• a cartridge support structure extending from an end of said hand gripping structure along a connection axis,
• said cartridge support structure having two opposing outer side surfaces, the distance between said opposing outer side surfaces decreasing in size along said axis away from said hand gripping structure such that said outer surfaces fit within and mate with inwardly directed surfaces of a recess on a cartridge during insertion of said cartridge support structure into said recess along said connection axis, said cartridge support structure having an end surface with an opening, and
• a spring-biased plunger that has a cam follower surface, is retained in said cartridge support structure and extends through said opening of said cartridge support structure.
