A razor cartridge is proposed. The razor cartridge may include a plurality of blades each including cutting edges, the plurality of blades including a first blade including a first cutting edge and a second blade including a second cutting edge. The razor cartridge may also include a blade housing longitudinally accommodating the plurality of blades to expose the cutting edge at least partially through an upper portion thereof, the blade housing including a first contact surface and a second contact surface respectively disposed in front and back of the cutting edge. The razor cartridge may further include an elastic arm elastically supporting the second blade. The first contact surface and the second contact surface may define a shaving plane. The first cutting edge may have a smaller exposure value than the second cutting edge with respect to the shaving plane while no external force acts.

Razor cartridge

An integral razor blade which is thin and has improved strength by shaping a geometrical structure of the razor blade and a razor cartridge using the same. The razor blade includes a base portion, a bent portion extending in a bent manner from one end of the base portion, and an edge portion extending from one end of the bent portion, a cutting edge being formed at one end of the edge portion. A first separation distance X between a straight line extending in a longitudinal direction from a front surface of the base portion and an end point of the cutting edge ranges from 0.3 mm to 1.0 mm.

Razor blade with bent portion

A razor handle includes a handle body including a head adapter and a grip portion extending from the head adapter; a connecting head configured to be coupled to a razor cartridge and coupled to the head adapter head so as to be pivotable around a rotational axis, the connecting head including a head side cam surface on one side thereof; and a plunger disposed on one side of the handle body and including a plunger side cam surface configured to perform a cam action with the head side cam surface, the plunger being configured to provide, through the cam action, recovery force to restore the connecting head to a rest position, wherein a contact area between the head side cam surface and the plunger side cam surface is smaller when the connecting head is deviated from the rest position than when the connecting head is in the rest position.

Razor handle and razor assembly using the same

Razor blade with bent portion and razor cartridge using the same

A razor handle assembly includes a gripping part gripped by a user, and a connecting part provided at one end of the gripping part to fix the cartridge. The connecting part includes a cartridge holder to which the cartridge is detachably coupled, and a holder clip which supports the cartridge holder. The cartridge holder is coupled to surround the outer side of an end portion of the holder clip.

Razor handle assembly and razor comprising the same

A razor cartridge includes a housing, a guard, a cap and a plurality of razor blades installed between the guard and cap in the housing, each blade including a base portion, a bent portion extending from an end of the base portion, and an edge portion extending from an end of the bent portion with a cutting edge formed at an end of the edge portion, wherein a first distance between a straight line extending from the front of the base portion and an end point of the cutting edge is in the range of 0.3 to 1.0 mm, wherein an overlap size defined as a distance by which the first distance of one of the razor blades is overlapped by an adjacent razor blade located behind the razor blade when the adjacent razor blade is projected in the vertical direction is less than or equal to 0.5 mm.
