Abstract

The present invention relates to razor heads and further to razors which include razor heads as defined. In one aspect of the invention the razor heads comprise at least one blade defining a plurality of cutting edges. The cutting edges are arranged to intercept at at least one point at which at least one angle of less than ninety degrees (90°) is formed between the cutting edges. This arrangement enables the cutting edges to impart cutting, sliding and rotary action onto hair being shaved.

Claims

1. A razor head for shaving comprising at least two blades defining a plurality of cutting edges, the cutting edges intercepting at at least one point at which at least one angle of less than ninety degrees is formed between the cutting edges.

2. A razor head as defined in claim 1, wherein the cutting edges intercept at one point.

3. A razor head as defined in claim 1, wherein the cutting edges intercept at a point substantially midway along their lengths.

4. A razor head as defined in claim 1, wherein two cutting edges are provided.

5. A razor head as defined in claim 4, wherein the cutting edges are substantially equal in length.

7. A razor head as defined in claim 4, wherein each cutting edge is defined by a separate blade.

8. A razor head as defined in claim 1, wherein the cutting edges define a cross.

9. A razor head as defined in claim 1, wherein the razor head comprises a substantially rectangular housing in which the plurality of cutting edges is mounted.

10. A razor head as defined in claim 9, wherein the plurality of cutting edges is affixed to the housing.

11. A razor head as defined in claim 1, wherein the head is provided with means for removably connecting the head to a handle.

12. A razor head as defined in claim 11, wherein said connecting means provides for relative movement between the razor head and handle in use.

13. A razor comprising a handle and a razor head connected thereto, the razor head being as defined in claim 1.

6. (canceled)

14-20. -20. (canceled)

21. A razor head for shaving, said razor head comprising:

a rectangular housing having a lateral axis extending between opposite sides of said rectangular housing, said housing also having top and bottom sides extending between said opposite sides of said rectangular housing;

a first blade mounted in said rectangular housing between said opposite sides of said rectangular housing, said first blade being mounted at a first angle with respect to said lateral axis of said rectangular housing; and

a second blade mounted in said rectangular housing between said opposite sides of said rectangular housing, said second blade being mounted at a second angle with respect to said lateral axis of said rectangular housing, said second angle being in a direction opposite said first angle;

wherein said first and second blades each have cutting edges which intersect at at least one point, and wherein the angle between said cutting edges which faces said opposite sides of said rectangular housing is less than ninety degrees.

22. A razor head as defined in claim 21, wherein said cutting edges intersect at a point substantially midway along their lengths.

23. A razor head as defined in claim 21, wherein said cutting edges are substantially equal in length.

24. A razor head as defined in claim 21, wherein said cutting edges define a cross therebetween.

25. A razor head as defined in claim 21, additionally comprising:

a mechanism for removably connecting said razor head to a handle.

26. A razor head as defined in claim 21, additionally comprising:

a plurality of flexible strips mounted in said rectangular housing near said bottom side thereof, said flexible strips operating to pull hair or stubble upwards before passing the blades there across, thereby providing for a closer shave.

27. A razor head as defined in claim 21, additionally comprising:

a flexible cleaning mechanism mounted in said rectangular housing, said cleaning mechanism upon application of pressure to a surface thereof moving between said first and second blades to enable shaved hairs and residual soap to be readily washed from said razor head.

28. A razor head for shaving, said razor head comprising:

a rectangular housing having a lateral axis extending between opposite sides thereof; and

at least two blades mounted in said rectangular housing between said opposite sides of said rectangular housing, said blades each have cutting edges which intersect at least one point;

wherein said cutting edges of said blades defining an angle therebetween which faces said opposite sides of said rectangular housing and is less than ninety degrees.
