Claims
- 1. A shaver handle comprising:
an elongated rigid inner core extending along a longitudinal axis; and an elongated, compressible outer layer formed around the inner rigid core, the compressible outer layer being provided with a series of axially spaced fins having a substantially uniform aspect ratio D:T, wherein D is a depth of each individual fin viewed in a direction transverse to the longitudinal axis and T is a thickness of the individual fin viewed in a direction parallel to the longitudinal axis, the aspect ratio being greater than the depth D of the individual fin.
- 2. The shaver handle as claimed in claim 1, wherein the aspect ratio D:T varies from about 1.2 to about 2.
- 3. The shaver handle as claimed in claim 2, wherein the aspect ratio D:T varies from about 1.4 to about 1.6.
- 4. The shaver handle as claimed in claim 1, wherein the fins are spaced apart at an axial spacing varying from about 0.6 to about 0.8 millimeters.
- 5. The shaver handle as claimed in claim 4, wherein the fins cover from about 50 to about 80% of the entire length of the shaver handle.
- 6. The shaver handle as claimed in claim 1, wherein the compressible outer layer has an elongated, continuous outer segment bridging two elongated continuous lateral segments, each of the continuous lateral segments having a respective series of the fins extending laterally outward from the continuous lateral segment, the depth of each fin progressively decreasing from a greater depth to a smaller depth as the fin extends inwards from the continuous outer segment, whereas the depth D is the greater depth of the fin.
- 7. The shaver handle as claimed in claim 6, wherein each of the fins has a respective outer portion located adjacent to the continuous outer segment and having the greater depth D.
- 8. The shaver handle as claimed in claim 8, wherein the outer portion of the fin has a curved circumference, the greater depth D being defined as a radial distance between a tangent to the curved circumference and a center of the curved circumference lying on the respective lateral segment.
- 9. A safety razor comprising: a razor blade unit; and a elongated handle extending along a longitudinal axis and supporting the blade unit, the elongated handle including an inner, relatively incompressible core and an outer relatively compressible layer formed around the inner, relatively incompressible core, the relatively compressible layer having a series of axially spaced-apart fins, each of the fins being shaped and dimensioned to have an aspect ratio D:T, wherein D is a depth of the fin and T is an axial thickness of the fin, the aspect ratio being greater than the depth D of the fin.
- 10. The safety razor as claimed in claim 9, wherein each of the fins is shaped and dimensioned to have a greater depth and a smaller depth, the depth D being the greater depth.
- 11. The safety razor as claimed in claim 10, wherein the aspect ratio D:T varies from about 1.2 to about 2.
- 12. The safety razor as claimed in claim 10, wherein the aspect ratio D:T varies from about 1.4 to about 1.6.
- 13. The safer razor as claimed in claim 9, wherein the fins are spaced apart at a uniform axial spacing varying from about 0.6 to about 0.8 millimeters.
- 14. The safety razor as claimed in claim 13, wherein the fins cover from about 50 to about 80% of the entire length of the elongated handle.
- 15. The safety razor as claimed in claim 9, wherein the outer, relatively compressible layer is made from an elastomeric material and has an elongated, continuous outer segment bridging two continuous lateral segments, each of the continuous lateral segments having a respective plurality of the fins extending laterally outward from the continuous lateral segment.
- 16. The safety razor as claimed in claim 15, wherein each of the fins has the depth progressively decreasing from the greater depth D to the smaller depth as the fin extends inwardly from the elongated, continuous outer segment of the outer compressible layer in a direction transverse to the longitudinal axis.
- 17. The safety razor as claimed in claim 15, wherein each of the fins has a respective outer portion extending between the continuous outer and lateral segments of the outer layer and provided with the greater depth D.
- 18. The safety razor as claimed in claim 17, wherein the outer portion of the fin has a curved circumference, the greater depth D being defined as a radial distance between a tangent to the curved circumference and a center of the curved circumference lying on the respective lateral segment of the outer compressible layer.
- 19. The safety razor as claimed in claim 1, wherein the inner, relatively incompressible core includes an inner portion and an outer portion provided with a pair of legs, the inner and outer portions having a common outer part bridging the pair of legs which extend inward from the common outer part in a direction transverse to the longitudinal axis and angularly outward from the inner recessed portion.
- 20. The safety razor as claimed in claim 15, wherein the fins are arranged in multiple groups located along each of the lateral segment of the outer compressible layer, each of the lateral segments having at least one indentation separating adjacent groups of the fins, the at least one indentation being spaced from a front end of the handle attached to the razor blade unit at a distance varying from about a to about ½ of the entire length of the handle, the handle having a smooth curved shape in a direction parallel to the longitudinal axis.
