Abstract

The invention features a hair removal device, such as a razor for dispensing a fluid during use. The hair removal device includes a fluid dispensing member which comprises an elongated elastomeric contact member for dispensing the fluid onto the skin in a wide and flat layer of fluid.

Claims

1. A hair removal device comprising:

a. a handle having a length that extends from a proximal end to a distal end and a transverse centerline, the handle comprising

i. a cavity for housing a fluid disposed within the handle, and

ii. an actuator adapted to displace the fluid from the cavity through a supply channel to an opening formed in said handle;

b. a fluid dispensing member comprises an elongated elastomeric contact region forming at least one dispensing orifice in fluid communication with said opening, said elongated elastomeric contact region comprising a lateral dimension which is generally perpendicular to said transverse centerline, wherein said fluid dispensing member is in fluid communication with said cavity via said opening, forming a fluid dispensing path, wherein said supply channel and said fluid dispensing path form a fluid flow path;

c. at least one one-way valve located at some point along said fluid flow path; and

d. a hair removal head having a lateral dimension.

2. The hair removal device of claim 1, wherein the ratio of the lateral dimension of the elongated elastomeric contact region to the lateral dimension of the hair removal head is from 1:

10 to about 1.5;

1.

3. The hair removal device of claim 2, wherein said ratio of the lateral dimension of the elongated elastomeric contact region to the lateral dimension of the hair removal head is from about 0.5:

1 to about 1;

1.

4. The hair removal device of claim 1, wherein said hair removal head has a top portion and a bottom portion, and wherein said elongated elastomeric contact region is positioned below said hair removal head in the vicinity of said bottom portion.

5. The hair removal device of claim 4, wherein said elongated elastomeric contact region is not in direct contact with said bottom portion of said hair removal head in a resting position.

6. The hair removal device of claim 4, wherein said elongated elastomeric contact region flexes towards said bottom portion of said hair removal head in an in-use position.

7. The hair removal device of claim 4, wherein said elongated elastomeric contact region is in direct contact with said bottom portion of said hair removal head in an in-use position.

8. The hair removal device of claim 4, wherein said elongated elastomeric contact region has a transverse central axis and rotates with respect to said transverse central axis.

9. The hair removal device of claim 4, wherein the ratio of the lateral dimension of the elongated elastomeric contact region to the lateral dimension of the hair removal head is from 1:

10 to about 1.5;

1.

10. The hair removal device of claim 1, wherein said hair removal head has a top portion and a bottom portion, and wherein said elongated elastomeric contact region is positioned below said hair removal head in the vicinity of said top portion

11. The hair removal device of claim 1, wherein said elongated elastomeric contact region forms said one-way valve.

12. The hair removal device of claim 11, wherein said one-way valve is selected from a flap valve, a slit valve, a duckbill valve, and a combination thereof.

13. The hair removal device of claim 1, wherein said elongated elastomeric contact region is separated from said one-way valve.

14. The hair removal device of claim 1, wherein said at least one dispensing orifice has a lateral dimension, wherein the ratio of the lateral dimension of the at least one dispensing orifice to the lateral dimension of the hair removal head is from 1:

10 to about 1;

1.

15. The hair removal device of claim 1, wherein said at least one dispensing orifice is biased to be sealed in a resting position.

16. The hair removal device of claim 15, wherein said at least one dispensing orifice opens when in an in-use position.

17. The hair removal device of claim 1, wherein said one-way valve is actuated by at least one of movement of the hair removal head, actuation of said pump, and a combination thereof.

18. The hair removal device of claim 1, wherein said fluid dispensing member is hingedly attached to said proximal end of said handle.

19. The hair removal device of claim 1, wherein said hair removal head comprises a razor cartridge.

20. The hair removal device of claim 1, wherein a hair removal composition is contained within said cavity, said hair removal composition being selected from shaving gels, shaving foams, shaving lotions, skin treatment compositions, conditioning aids, depilatories, lotions, moisturizers, and mixtures thereof.
