Razor cartridge comprising mechanochromic layer
The present disclosure relates to a razor cartridge including a housing having a front edge and a rear edge; at least one razor blade disposed between the front edge and the rear edge; and a mechanochromic layer disposed on the at least one razor blade, wherein the mechanochromic layer comprises a mechanochromic material.
1. A razor cartridge comprising:
a housing having a front edge and a rear edge,
at least one razor blade disposed between the front edge and the rear edge, and
a mechanochromic layer disposed on the at least one razor blade, wherein the mechanochromic layer comprises a mechanochromic material.
2. The razor cartridge according to claim 1 , wherein the at least one razor blade is flexible.
3. The razor cartridge according to claim 1 , wherein the color change of the mechanochromic layer is reversible.
4. The razor cartridge according to claim 1 , wherein the mechanochromic layer is configured to change color when the at least one blade is deformed.
5. The razor cartridge according to claim 1 , wherein the at least one razor blade is disposed on a support member configured to attach the at least one razor blade to the razor cartridge; or,
wherein the at least one razor blade comprises a support section, wherein the support section is configured to attach the at least one razor blade to the razor cartridge.
6. The razor cartridge according to claim 1 , wherein the at least one razor blade is disposed on a support member configured to attach the at least one razor blade to the razor cartridge by being inserted into a blade receiving section of the razor cartridge; or
wherein the at least one razor blade comprises a support section, wherein the support section is configured to attach the at least one razor blade to the razor cartridge by being inserted into a blade receiving section of the razor cartridge.
7. The razor cartridge according to claim 1 , wherein the at least one mechanochromic layer is configured to face towards the shaved surface when used for shaving; or
wherein the razor blade comprises a cutting-edge, wherein the cutting-edge defines a cutting-edge-angle, and wherein the cutting-edge angle is disposed between the mechanochromic layer and the support section.
8. The razor cartridge according to claim 1 , wherein the mechanochromic layer has a thickness between about 1 μm to about 2000 μm.
9. The razor cartridge according to claim 1 , wherein the mechanochromic layer has a thickness between about 5 μm to about 400 μm.
10. The razor cartridge according to claim 1 , wherein the mechanochromic material is configured to change color when exposed to a mechanical stress between about 0.3 MPa to about 3 MPa.
11. The razor cartridge according to claim 1 , wherein the mechanochromic material is configured to change color when exposed to a mechanical force between about 0.1 N to about 5 N.
12. The razor cartridge according to claim 11 , wherein the mechanical force is a tensile force.
13. The razor cartridge according to claim 1 , wherein the mechanochromic material comprises a photonic material, a piezophotonic material, a polymer composite with electro/thermo-induced luminescent and chromic substance, a microcrack structure design composite material, a mechanophore or mixtures thereof.
14. The razor cartridge according to claim 1 , wherein the mechanochromic material comprises a mechanophore-linked polymer or composite.
15. The razor cartridge according to claim 1 , wherein the at least one razor blade has a thickness between about 0.02 mm to about 0.2 mm.
16. The razor cartridge according to claim 1 , wherein the at least one razor blade exhibits a tensile strength between about 500 MPa to about 2000 MPa.
17. The razor cartridge according to claim 1 , wherein the at least one razor blade exhibits a tensile strength between about 800 MPa to about 1300 MPa.
18. The razor cartridge according to claim 1 , wherein the razor cartridge comprises at least two razor blades.
19. A shaving razor assembly comprising:
a razor handle, and
a razor cartridge according to claim 1 , wherein the razor cartridge is either releasably attached to the razor handle via a pivotable or non-pivotable connection, integrally formed with the razor handle via a non-pivotable connection, or integrally formed with the razor handle via a pivotable connection.
20. A method for manufacturing a razor cartridge, wherein the method comprises coating at least one razor blade with a mechanochromic layer and assembling the razor blade into a razor cartridge; or,
assembling a razor cartridge blank comprising at least one razor blade and coating the at least one razor blade with a mechanochromic layer.
