Abstract

The invention relates to a device for treating the hair including a housing for receiving a cosmetic product refill, a heating element for the hair to be treated, and a device that prevents the reception of the cosmetic product refill in the housing, depending on the temperature of the heating element.

First claim

1 . A device for treating the hair, comprising:
a housing for receiving a cosmetic product refill; a heating element for the hair to be treated; and a device that prevents the reception of the cosmetic product refill in the housing, depending on a temperature of the heating element.

2 . The device for treating the hair according to claim 1 , wherein the device that prevents the reception of the cosmetic product refill in the housing includes a lug that projects into the housing.

3 . The device for treating the hair according to claim 2 , wherein the lug is guided in translation in a direction substantially perpendicular to the direction of insertion of the refill into the housing.

4 . The device for treating the hair according to claim 2 , wherein the lug is guided in translation substantially in the direction of removal of the refill from the housing, such that, when the heating element cools, the lug ejects the refill from the housing.

5 . The device for treating the hair according to claim 2 , wherein the device that prevents the reception of the refill in the housing includes a bimetallic strip designed such that:
when the bimetallic strip is at a temperature below a first threshold temperature, the lug projects into the housing, and such that: when the bimetallic strip is at a temperature above a second threshold temperature, the lug allows the introduction of the cosmetic product refill into the housing.

6 . The device for treating the hair according to claim 5 , wherein the bimetallic strip is fastened to the heating element so as to create a thermal connection between the heating element and the bimetallic strip.

7 . The device for treating the hair according to claim 5 , wherein the device that prevents the reception of the refill in the housing includes a return spring for returning the lug into a position in which it allows the refill to be received in the housing.

8 . The device for treating the hair according to claim 5 , wherein an arm is secured to the bimetallic strip such that the arm projects from the device for treating the hair, at least in one of the positions of the bimetallic strip in which it allows or prevents the reception of the refill in the housing.

9 . The device for treating the hair according to claim 1 , further comprises two arms that are movable with respect to one another between a moved-together configuration for treating the hair and a spaced-apart configuration for introducing hair to be treated between said arms, one of the arms including the housing for receiving the cosmetic product refill and the heating element.

10 . The device for treating the hair according to claim 1 further comprises a cosmetic product refill, the cosmetic product refill including a reservoir that is intended to be at least partially received in the housing and an applicator member in fluidic communication with the reservoir, the applicator member being intended to extend at least partially out of the housing.

11 . The device for treating the hair according to claim 2 , wherein the lug is guided in translation in a passage formed in the device for treating the hair.

12 . The device for treating the hair according to claim 5 , wherein the first threshold temperature is greater than or equal to the second threshold temperature.

13 . The device for treating the hair according to claim 7 , wherein the bimetallic strip prevents the return spring from moving the lug into the position in which it allows the cosmetic product refill to be received in the housing as long as the temperature of the bimetallic strip is below the first threshold.
