Abstract
Abstract A holder for a razor blade is provided comprising a pair of spaced limbs having opposed internal surfaces defining an elongate seat which in use receives a strip blade, the seat having a depth less than the depth of a blade to be used so that the cutting edge of the blade projects beyond the spaced limbs and the spacing between the limbs being such that a blade to be used is held in position during use by surface adhesion between said opposed internal surfaces and the surface of the blade, the depth of the seat being limited by means forming the back of the seat against which the blade abuts to limit penetration of the blade between the limbs, said limit means extending only a part of the length of said seat and including a pivot point spaced from one end of the seat, removal of a blade being effected by rearward pressure on the blade at said one end of the seat so that the blade pivots about said pivot point.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
189 words
A holder for a blade comprising a pair of spaced limbs permanently fixed in position relative to one another and having opposed internal surfaces defining an elongate seat which in use receives a strip blade, the seat having a depth less than the depth of a blade to be used so that the cutting edge of the blade projects beyond the spaced limbs and the spacing between the limbs being such that a blade to be used is held in position during use primarily by surface adhesion between said opposed internal surfaces and the surface of the blade, the depth of the seat being limited by means forming the back of the seat against which the blade abuts to limit penetration of the blade between the limbs, said limit means extending only a part of the length of said seat so that a pivot point is formed spaced from one end of the seat, whereby rearward pressure on the blade at said one end of the seat causes the blade to pivot about said pivot point releasing the blade at the other end of the seat to enable removal.
Claim 2
Dependent Claim
189 words
A holder for a blade comprising a pair of spaced limbs permanently fixed in position relative to one another and having opposed internal surfaces defining an elongate seat which in use receives a strip blade, the seat having a depth less than the depth of a blade to be used so that the cutting edge of the blade projects beyond the spaced limbs and the spacing between the limbs being such that a blade to be used is held in position during use primarily by surface adhesion between said opposed internal surfaces and the surface of the blade, the depth of the seat being limited by means forming the back of the seat against which the blade abuts to limit penetration of the blade between the limbs, said limit means extending only a part of the length of said seat so that a pivot point is formed spaced from one end of the seat, whereby rearward pressure on the blade at said one end of the seat causes the blade to pivot about said pivot point releasing the blade at the other end of the seat to enable removal.
Claim 3
Dependent Claim
38 words
A holder for a blade according to claim 1 wherein the limbs are of substantially the same rectangular shape and are spaced by a rectangular intermediate plate having a length and breadth smaller than that of the limbs.
Claim 4
Dependent Claim
14 words
A holder according to claim 2 wherein the intermediate plate constitutes said limit means.
Claim 5
Dependent Claim
43 words
A holder according to claim 3 wherein the limbs and intermediate plate are flush along the back and the other end, the pivot point being formed by that front corner of the rectangular intermediate plate not flush with the edge of the limbs.
Claim 6
Dependent Claim
202 words
A shaving razor having a handle and a holder for a blade wherein the holder for the blade comprises a pair of spaced limbs permanently fixed in position relative to one another and having opposed internal surfaces defining an elongate seat which in use receives a strip blade, the seat having a depth less than the depth of a blade to be used so that the cutting edge of the blade projects beyond the spaced limbs and the spacing between the limbs being such that a blade to be used is held in position during use primarily by surface adhesion between said opposed internal surfaces and the surface of the blade, the depth of the seat being limited by means forming the back of the seat against which the blade abuts to limit penetration of the blade between the limbs, said limit means extending only a part of the length of said seat so that a pivot point is formed spaced from one end of the seat whereby rearward pressure on the blade at said one end of the seat causes the blade to pivot about said pivot point releasing the blade at the other end of the seat to enable removal.
