Abstract
A shaver handle has an outer layer made from a compressible elastomeric material and formed around an inner rigid core. The elongated outer layer is provided with a series of 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 a longitudinal axis of the shaver handle and T is a thickness of each of the fins viewed in a direction parallel to the longitudinal axis, the aspect ratio is greater than the depth D.
Claims20
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.
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.
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.
