Abstract

The present invention relates to a refill ( 20 ) for an appliance for treating the hair, comprising:
a reservoir ( 23 ) containing a haircare product and comprising a rigid or semi-rigid body ( 86 ) in contact with the product, and an end piece ( 53 ) for dispensing the product contained in the reservoir ( 23 ), a fluidic connection disposed between the dispensing end piece ( 53 ) and the reservoir ( 23 ), a support ( 83 ) for the dispensing end piece ( 53 ), the fluidic connection and at least a part of the reservoir ( 23 ), this support being produced in an integral manner, the refill ( 20 ) extending along a longitudinal axis (Z), the length (l) of the support ( 83 ), measured along said longitudinal axis (Z), being less than that (L rech ) of the refill ( 20 ).

First claim

The invention claimed is:

1. Refill for an appliance for treating hair, comprising:
a reservoir configured to contain a haircare product and comprising a rigid or semi-rigid body configured to be in contact with the product,
a dispensing end piece configured to dispense the product contained in the reservoir,
a fluidic connection disposed between the dispensing end piece and the reservoir,
an applicator member configured to: (i) receive the product from the dispensing end piece, and (ii) apply the product to the hair, and
a support that supports the dispensing end piece, the fluidic connection, and at least a part of the reservoir, the support being produced in an integral manner,
the refill extending along a longitudinal axis, a length of the support, measured along said longitudinal axis, being less than a total length of the refill.

2. The refill according to claim 1 , wherein the reservoir extends along a longitudinal axis and has a single outlet for the product at one end.

3. The refill according to claim 1 , wherein a length of the reservoir is less than half the total length of the refill, measured along said longitudinal axis.

4. The refill according to claim 1 , wherein the internal volume of the reservoir is configured to vary while the refill is being used.

5. The refill according to claim 1 , wherein the dispensing end piece has at least one dispensing orifice.

6. The refill according to claim 1 , wherein the dispensing end piece is connected to the reservoir by a flexible duct.

7. The refill according to claim 1 , wherein the dispensing end piece is pre-filled with the product.

8. The refill according to claim 1 , wherein the dispensing end piece and the reservoir have respective longitudinal axes that are not coincident.

9. The refill according to claim 1 , wherein the maximum capacity of the reservoir is between 2 ml and 20 ml.

10. The refill according to claim 1 , wherein the rigid or semi-rigid body of the reservoir has a tubular shape.

11. The refill according to claim 1 , wherein the reservoir comprises a follower piston.

12. The refill according to claim 11 , wherein the follower piston is configured to move unidirectionally by virtue of the presence of an anti-recoil system.

13. The refill according to claim 1 , wherein the reservoir extends along a longitudinal axis and comprises a flexible wall.

14. The refill according to claim 1 , wherein the applicator member at least partially covers the dispensing end piece.

15. The refill according to claim 1 , wherein the applicator member comprises a porous material and/or a material that is able to release or diffuse the product.

16. The refill according to claim 1 , wherein the dispensing end piece is carried by a support rigidly connected to the reservoir.

17. The refill according to claim 16 , wherein the rigid or semi-rigid body of the reservoir and the support are produced in an integral manner.

18. The refill according to claim 1 , wherein the applicator member is held on the support by a holding element fixed to the support.

19. The refill according to claim 18 , wherein the applicator member is configured to be removable from the support.

20. The refill according to claim 1 , further comprising one or more components of a pump for supplying the dispensing end piece with the product present in the reservoir.

21. The refill according to claim 20 , wherein the components of a pump is at least one peristaltic pump tube and/or a flap-valve pump.

22. The refill according to claim 21 , wherein the dispensing end piece is connected to the reservoir by a flexible duct, and the peristaltic pump tube is formed by a portion of said flexible duct.

23. The refill according to claim 1 , further comprising a member to close the refill when the refill is not in use.

24. Device for treating hair, comprising:
at least two arms that are able to move relative to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for inserting a lock of hair to be treated between said arms,
the refill according to claim 1 , the refill being disposed in a removable manner on one of the two arms.

25. The device according to claim 24 , wherein the moving together of the arms actuates said pump.

26. The device according to claim 24 , wherein the arm carrying the refill has a relief designed to engage with the reservoir in order to cause the internal volume thereof to decrease when the refill is fitted on the device.

27. The device according to claim 24 , which is a straightener, wherein each of the two arms comprising a heating element.
