For the purposes of the present invention, the term "cosmetic product" is intended to mean a product as defined in Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 relating to cosmetic products.

The cosmetic product intended to be applied by the applicator according to the invention is in particular in the form of a powder, a compacted solid, or a fluid such as a liquid. The product is advantageously a product intended to be placed on the keratin fibers of a user, such as the eyelashes or the eyebrows. The product is for example a makeup product such as a mascara.

It is known to apply a makeup product such as a mascara with a heating applicator, intended to curl and / or lengthen the eyelashes.

In the embodiment shown in Figure 1, the application unit 12 is adapted to be reversibly assembled with a reservoir 30 of cosmetic product, as will be detailed below. At the second end of the rod 16, the application unit 12 thus comprises a reversible assembly element 32 with said reservoir 30. The assembly element has for example the shape of a cap 32 defining a cylindrical cavity 34. A bottom of said cavity 34 is fixed to the second end of the rod 16, said cavity being oriented towards the application head 22. A wall of the cavity 34 has a tapping 36.

Preferably, the first connector 28 is integral with the cap 32, on the opposite side to the cavity 34. The gripping member 14 comprises an outer cover 48 of elongated shape, extending along a second longitudinal axis 50. The organ gripping 14 further comprises a source of electrical energy 52, contained in the cover 48. The power source 52 is particularly battery type battery or electric.

At a first axial end, the cover 48 preferably has a base 53 in the form of a flat surface substantially perpendicular to the second longitudinal axis 50.

At a second axial end of the cover 48, the gripping member 14 comprises a second electrical connector 54, electrically connected to the energy source 52.

As will be described below, the second electrical connector 54 is adapted to cooperate with the first electrical connector 28 of the application unit 12, so that the energy source 52 provides energy to the heating element 20 .

Preferably, the gripping member 14 further comprises an electronic device 56 regulating the supply of energy to the heating element 20. The electronic device is for example an electronic card 56, received inside the cover 48 and electrically connected to the power source 52 and the second connector 54.

Preferably, the gripping member 14 further comprises one or more control buttons (not shown) and / or one or more LED-type indicator lights (not shown), disposed on an outer face of the cover 48 and electrically connected to the electronic card 56.

In FIG. 1, the application unit 12 and the gripping member 14 are presented in a dissociated configuration. The application unit 12 and the gripping member 14 are able to be assembled in a reversible manner to form the applicator 10.

In particular, the first connector 28 and the second connector 54 are able to be assembled in a reversible manner to electrically connect the energy source 52 and the heating element 20.

The first connector 28 and the second connector 54 are respectively arranged along a first and a second connection axis. The connection axes are merged into the assembled configuration of the connectors 28, 54. In the example of FIG. 1, the first connection axis corresponds to the first longitudinal axis 18 and the second connection axis corresponds to the second longitudinal axis 50. , the connection axes are inclined with respect to the longitudinal axes 18, 50.

The first 28 and second 54 connectors are able to be assembled and dissociated in a reversible manner. The first connector 28 and the second connector 54 respectively comprise a first 60 and a second 62 contact surfaces. The first 60 and second 62 contact surfaces, of complementary shapes, are in contact with one another in assembled configuration of the connectors 28, 54. Preferably, each of the first 60 and second 62 contact surfaces comprises at least two points of contact away from each other.

In order to facilitate assembly and dissociation, the first 28 and second 54 connectors are configured to allow contact surfaces 60, 62 to be brought into contact and / or dissociated by translation along the first 18 and / or the second 50 axes. connection, without rotating the first and second connectors relative to each other about said connection axis.

In other words, it is possible to assemble and disassociate the connectors 28, 54 by a pure translation movement, plug-in type, without association with a rotational movement as in the case of a screw.

In particular, the contact surfaces 60, 62 are devoid of thread-like reliefs. The application unit 12 and the gripping member 14 of the applicator 10 can thus be easily disconnected, by traction along the axis 18, 50, and reconnected in a reverse movement.

According to one embodiment, at least one of the contact surfaces 60, 62 is able to deform during the translational movement of the connectors 28, 54 relative to each other according to the first 18 and / or the second 50 axes. Said contact surface is for example formed of at least one flexible metal blade.

According to one embodiment, the first 28 and second 54 connectors are of a type allowing plugging flat, for example USB port type. However, such connectors require an angular indexing of said connectors relative to each other.

According to another preferred embodiment, at least one of the contact surfaces 60, 62 has a symmetry of revolution, respectively according to the first 18 and / or the second 50 longitudinal axis. Thus, angular indexing is not necessary.

For example, the first 28 and second 54 connectors form a "jack" type electrical outlet, the first connector 28 preferentially forming the female socket and the second connector 54 preferably forming the plug of said "jack" jack. In particular, the plug 54 has an elongated shape, of revolution along the second axis 50.

Preferably, the "jack" format 2.5 mm is used.

In assembled configuration, the first 28 and second 54 connectors have sufficient mechanical strength to secure the application unit 12 and the gripping member 14. Preferably, the gripping member comprises an additional mechanical assembly means 64 reversible with the application unit 12. Said additional means is for example a ring 64, arranged axially around the second connector 54 and able to be inserted reversibly around the cap 32.

The reservoir 30 shown in FIG. 3 is able to be assembled reversibly with the application unit 12 in order to form a cosmetic product packaging assembly according to one embodiment of the invention. The reservoir 30 comprises an outer wall 68 of elongate shape, for example cylindrical. The outer wall 68 defines an internal cavity 70, able to receive cosmetic product. In particular, the internal cavity 70 is able to contain a fluid product such as a mascara composition.

One end of the wall 68 has an axial opening 72, allowing the introduction into the cavity 70 of a portion of the application unit 12, in particular of the application head 22. Preferably, close to the opening axial 72, an inner face of the wall 68 carries a wiper 74, formed of a flexible frustoconical skirt. The wiper 74 is able to retain a portion of the cosmetic product in the cavity 70 when the application head 22 is extracted from said cavity. In the vicinity of the axial opening 72, the reservoir 30 comprises a reversible assembly element 76 with the application unit 12. The element 76 is able to cooperate with the assembly element 32 of said unit. For example, the reversible assembly element 76 is a thread carried by an outer face of the wall 68, said threading being capable of cooperating with the tapping 36 of the cap 32.

In the closed position, when the threaded cap 32 is screwed onto the thread 76, the application unit 12 is completely received in the cavity 70 with the exception of said cap 32. Said cap then closes the opening 72 of the reservoir.

In the case where the energy source 52 of the gripping member 14 is an electric battery, the gripping member 18 is adapted to cooperate with a charger 20 to recharge said battery. The charger 80 is shown in FIG.

The charger 80 comprises a base 82 and a third electrical connector 84, adapted to cooperate with the second connector 54. The third connector 84 has for example a shape identical to the first connector 28, such as the shape of a socket "jack" female .

The base 82 has a fourth connector 86 adapted to be connected to an external source of electrical energy. The fourth connector 86 is for example a mains socket or a USB socket.

According to one embodiment, the application unit 12 and the gripping member 14 are marketed in a dissociated configuration, in the form of a kit for producing an applicator 10. According to a first variant, the application unit 12 is marketed assembled to a reservoir 30 containing cosmetic product, thus forming the cosmetic product packaging assembly described above.

According to a second variant, the electric power source 52 of the gripping member 14 is a rechargeable battery, and the kit further comprises an electric charger 80.

A method of making and using an applicator 10 from the kit described above will now be described. It is considered that the application unit 12 is supplied assembled to a tank 30 in the closed position.

One end of the ring 64 of the gripping member 14 is positioned around the cap 32 of the application unit 12, so that the first 18 and the second 50 axes coincide. The gripping member 14 is then brought closer to the application unit 12, by sliding along the first 18 / second axis 50, so as to bring into contact the first 60 and second 62 contact surfaces of the electrical connectors 28, 54 and completely inserting the ring 64 around the cap 32.

Said cap 32 is then unscrewed from the thread 76 and the application unit 12 is extracted from the reservoir 30. The application unit 12 and the gripping member 14, in assembled configuration, form the cosmetic product applicator 10 , more particularly mascara.

Said applicator 10 is then used, for example to coat mascara eyelashes of a user. The energy source 52 allows the heating element 20 to diffuse heat, which has the effect of drying and / or bending the eyelashes in contact with the application head 22. Depending on the nature of the cosmetic product, the heat can also cause the melting of said product.

Preferably, the user regulates the temperature and / or the duration of diffusion of the heat, by means of the control buttons carried by the cover 48. At the end of the use, the user reintroduces the application head 22 in the tank 30 and screw the cap 32 on the thread 76. The user then exerts a traction along the first 18 / second 50 longitudinal axis, so as to dissociate the application unit 12 and the gripping member 14. After dissociation, in the case where the power source 52 is a battery, the gripping member 14 is preferably put to recharge on the charger 80.

Thus, the gripping member 14, ie the portion of the applicator 10 containing the energy source 52 and the electronics 56, is never in contact with the cosmetic product contained in the reservoir 30.

Preferably, at the end of use, the applicator 10 is placed vertically on its base 53, in order to allow the heating element 20 to cool before reintroducing the application unit 12 into the reservoir 30. The cavity 34 then receives possible mascara runs and prevents their contact with the first connector 28.

According to one embodiment of the invention, the kit described above comprises a plurality of application units 12. Preferably, each application unit 12 is assembled to a reservoir 30 containing cosmetic product, thus forming a plurality of cosmetic product packaging assemblies as previously described.

According to a first variant, said packaging sets of the kit are all identical. In a second variant, the cosmetic product and / or the application head 22 is different (e) from one set to another.

Thus, it is possible to use the same gripping member 14 while changing the cosmetic product and / or mascara brush shape, which improves the modularity of the device.

Similarly, it is possible to use the same gripping member 14 by replacing a used application unit 12. The gripping member 14 representing the most expensive part of the applicator 10, the cost of the device compared to the duration of use is reduced.
