Definitions
- the present invention relates to an integrated razor blade and a razor using the same, and more particularly, to a razor blade maximized in stiffness by shaping the geometry of the razor blade.
- Factors affecting shaving performance include the frictional resistance between the blade edge and the skin and the sharpness of the blade edge, both of which include the cutter force exerted on the hair by the blade.
- Increasing the number of blades in a razor generally improves the shaving efficiency of the razor and improves the distribution of compressive force on the skin, but increases drag force.
- the area occupied by the blade increases, or the gap between the cutting edges of the blade decreases.
- Increasing the area occupied by the razor blade can adversely affect shaving performance. If the spacing between the blades is reduced, the shaving performance may be deteriorated, and the shaving debris may also be difficult to remove.
- increasing the spacing between the razor blades may improve shaving performance, but there is a problem of increasing the risk of cuts and cuts. Therefore, it is important to properly adjust the spacing between the blades.

- the distance between the first razor blade and the last razor blade is preferably 1.0 mm to 8.0 mm.
- the distance between the plurality of razor blades is preferably 0.5mm to 0.9mm.
- the said edge part is made into the shape which recessed back surface part.
- the cutting edge preferably has a structure that protrudes in a circular shape to distribute the cutting pressure when the hair is cut.
- the distance between the center portion of the cutting edge and a straight line connecting both ends of the cutting edge is 0.01 mm to 2.0 mm.
- the distance between the center portion of the cutting edge and a straight line connecting both ends of the cutting edge is 0.2 mm.
- the thickness of the razor blade is preferably 0.075mm to 0.2mm.
- a razor blade can be provided that is thin and excellent in rigidity.
- according to the present invention can provide a razor blade formed integrally with the cutting edge and the support can increase the production efficiency of the razor blade.
- the thickness of the razor blade becomes thin, the shaving dregs can be easily discharged.
- FIG. 2 is a detailed view of the razor cartridge according to the prior art
- FIG. 3 is a cross-sectional view taken along the line A-A 'of FIG.
- FIG. 4 is a perspective view of a razor blade according to the present invention.
- FIG. 9 is a graph showing the stiffness test results of the blade according to the present invention and the blade according to the prior art
- Figure 4 shows an embodiment of a razor blade according to the present invention.
- the razor blade 40 extends from an edge portion 42 having a cutting edge 422 cutting hair, a connection portion 44 extending from the edge portion 42, and the connection portion 44. It can be confirmed that the support part 46 which supports the razor blade is integrally formed.
- FIG. 5 is an enlarged view of portion A of FIG. 4
- FIG. 6 is an enlarged view of only the edge portion 42
- FIG. 7 is a top view of the razor blade from above.
- the edge portion 42 has a curved surface in which the front portion 424 is convex and the back portion 426 is concave.
- the cutting edge 422 has a curved structure, so that the center portion of the razor blade protrudes, thereby forming the dimensions of a and d.
- This dimension depends on the total length of the razor blade, which may be comprised from 0.01 mm to 2.0 mm.
- the length of a and d is preferably about 0.2 mm.
- the radius is 216.95mm.
- the distance from the cutting edge 422 to the support 46 may be configured from 1.0mm to 3.0mm, preferably 1.8mm.
- the height c of the blade can be comprised from 1.5 mm to 5.0 mm, with 2.5 mm being preferred.

- the material of the housing 62 is made of synthetic resin, but may be made of other materials such as wood or metal, if necessary.
- the guard rubber 64 is formed adjacent to the cutting edge of the razor blade, and serves to make the razor blade easily cut by raising the hair on the skin in contact with the shaving blade.
- the lubrication band 66 is installed on the opposite side of the cutting edge direction of the blade 40 for the skin moisturizing and soothing effect.
- the lubrication band 66 may contain chamomile, olive, and allatoin components so that the user may feel more refreshed after shaving.
- the clip 68 is used to prevent the blade 40 from leaving the housing.
- Figure 9 shows the results of the performance test of the blade according to the present invention and the blade according to the prior art.
- the thickness of the razor blades is 0.075 mm (Example 1) and 0.1 mm (Example 2), and the conventional razor blades are currently available in G company products (product 1 and product 2). Was used.
- Instron 5542 tensile compressor from Instron was used as a test instrument.
