DISPOSABLE RAZOR BLADE CARTRIDGE, RAZOR, METHOD FOR CONNECTING CARTRIDGE TO HANDLE IN PROPER DIRECTION, AND COMBINED SHAVING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a shaving system which connects a disposable razor blade cartridge to a handle in the proper direction.

SOLUTION: A disposable razor blade cartridge 12 includes a cartridge connecting structure 16 for connecting a blade unit 14 to a handle 63. The connection is made by moving the handle 63 along a connection axis toward the cartridge connecting structure 16. The cartridge connecting structure 16 is provided with an oblique slot 80 functioning as a keyway for catching a corresponding key structure on the handle 63 when the handle 63 moves along the connection axis, so as to ensure that the handle 63 moves in the proper direction. The cartridge connecting structure 16 has an opening in parallel with the connection axis, in which the oblique slot 80 is disposed. Consequently, when the cartridge 12 is being connected with the handle 63, the opening and the oblique slot 80 are not blocked with the key structure.
