ABSTRACT:
A shaving system comprises novel components of a razor handle (1), a razor blade cartridge (2), and a magazine (5) holding a supply of cartridges. The handle and magazine are adapted to cooperate so that a used cartridge on the handle is replaced by (i) inserting the used cartridge into an empty magazine compartment, which unlatches the handle from the cartridge; (ii) moving the handle along the magazine towards a next adjacent compartment accommodating a fresh cartridge, firstly to disconnect the handle from the used cartridge which is left in its compartment and secondly to latch the handle onto the fresh cartridge held in the next compartment; and (iii) withdrawing from the magazine the handle with the fresh cartridge attached. Thus, the cartridges are dispensed from the magazine in turn with each cartridge replacement operation being effected by a single stroke of the handle relative to the magazine, this stroke having distinct components of insertion, advancement and withdrawal. A novel handle and cartridge coupling system is used, the cartridge having key elements (14) which engage in slots (15) provided on the handle so that the handle is connected to the cartridge by displacement relative thereto in a direction transverse to the cartridge and substantially parallel to its front face (25), and latch devices (18) which engage in notches (17) at the ends of the cartridge being provided on the handle to lock the cartridge against detachment from the handle. Conveniently, the latch devices and notches (17, 18) define a pivot enabling pivotal movement of the cartridge on the handle.
