本考案は、下方ガイド面を広くし、替刃を上方
に配置してひげ剃り時における安定性と剃り味を
よくした替刃式安全剃刀に関するものである。[Detailed description of the invention] (Field of industrial application) This invention is a replaceable blade safety razor that has a wider lower guide surface and a replaceable blade placed above to improve stability and shaving quality when shaving. It is related to.

易に剃ることができないという問題もあつた。 However, in the conventional type, the length W' of the lower guide surface 22 is significantly shorter than the overall length W' of the cartridge case 21, and the replaceable blade 24 is arranged near the lower guide surface 22. Due to the reaction force applied to the replaceable blade 24 when shaving, the cartridge case 21 tends to rotate in the direction of the arrow, and the tangential plane B connecting the lower guide surface 22 and the upper guide surface 23 tends to separate from the skin surface A. shall be. Therefore, there was a problem that stability during shaving was poor, and the contact angle θ' of the replaceable blade 24 with respect to the skin surface A changed, resulting in poor shaving quality. Moreover,
Since the replaceable blade 24 is disposed near the narrow lower guide surface 22, there is also a problem in that it is not possible to easily shave under the nose, under the eyebrows, or in the recessed area.

されたとはいえない。 In addition, some of the conventional safety razors with replaceable blades include
There is a method that attempts to control the effective exposure amount of the blade edge of a replaceable blade and the angle between the blade and the skin so as not to cause cuts as shown in Japanese Patent No. 55-141279. When the pressure applied to the skin from the disposable blade increases, for example by rotating the handle upwards relative to the disposable blade, the skin bulges in the span area between the blade edge of the disposable blade and the guard element (comb). Instead of a guard element having a curved engagement surface with a small radius of curvature that may injure the skin, the guard element has a skin engagement guide surface with a sufficient area and is placed sufficiently close to the blade edge to prevent the skin from getting into it. More preferably, the skin engagement control surface of the cap member (top plate) of the replaceable blade is provided on substantially the same plane as the guard element, so that the blade remains substantially constant even when the handle angle or the blade pressure changes. /Maintaining the contact angle with the skin improves the shave quality. however,
As explained earlier, if the replacement blade is not placed upward, the cartridge case will rotate outward due to the reaction force applied to the blade edge when shaving, and the tangential plane connecting the upper and lower guide surfaces will be at the skin surface. It cannot be said that the problem of stability and shaving quality deteriorated due to the contact angle changing as the blade tries to separate from the surface has not been solved.

ガイド面よりも広く形成した構成とされる。(Means for Solving the Problems) The present invention provides a guide surface that is formed over the entire length of the cartridge case and is pressed against the skin surface, with the cutting edges of one or more replaceable blades facing the guide surface. In a replaceable blade safety razor, the surface is formed with a lower guide surface that is on the lower side with the cutting edge of the replaceable blade as a boundary, and an upper guide surface that is on the upper side of the same cutting edge,
The cutting edge of the one or more replaceable blades located between the lower guide surface and the upper guide surface is arranged at 2/3 or higher than the total length of the cartridge case, and the lower guide The upper guide surface is configured to be wider than the upper guide surface.

れる。(Function) Since the above-mentioned method is adopted, when the cutting edge of the disposable blade receives a reaction force from the skin surface during shaving operations, the cartridge case uses the cutting edge of the disposable blade as a fulcrum to prevent the cartridge case from becoming unstable. This prevents the phenomenon of unintentional rotation.
The posture of the cartridge case pressed against the skin surface is stabilized in a state where the contact surface connecting the lower guide surface and the upper guide surface is in close contact with the skin surface, and the beard is shaved.
