- Heating of the end of the stick S can take place by conduction, in contact with a hot surface, as described above.
- the heating means comprises a heating surface which can be brought to the appropriate temperature by any heating means, for example an electrical resistance. Heating of the end of the stick can still be carried out without contact, for example by IR radiation and / or convection, and / or by vibration and / or radio-electric radiation, or any other source providing heat.
- the housing 40 may comprise any suitable sensor, in particular an optical sensor, capable of evaluating the distance between the end 11 of the stick and the heating means 50, in order to allow it to start up only when when a predefined distance is respected and / or in order to adjust the heating power as a function of the distance between the heating means and the end of the stick S.
- any suitable sensor in particular an optical sensor, capable of evaluating the distance between the end 11 of the stick and the heating means 50, in order to allow it to start up only when when a predefined distance is respected and / or in order to adjust the heating power as a function of the distance between the heating means and the end of the stick S.
- the heating means 50 may be a heating system by emitting infrared radiation towards the end 11 of the stick, for example by means of a halogen or incandescent lamp, or by blowing hot air towards the end 11.
- the end 11 of the rod S may be further heated by exposure to radioelectric radiation, for example microwaves, focused at the end 11 of the rod S.
- radioelectric radiation for example microwaves
- the end 11 of the S stick can be warmed by ultrasonic vibrations.
- the heating device 60 comprises a heating means 62 which is integral with the base part 2 and which can comprise, as illustrated, a ring-shaped heating element 62, which can The heating member 62 is for example of section greater than or equal to that of the stick S.
- the heating device 60 may comprise, for example, a control member 64 on which the user can press to trigger the operation of the heating member 62.
- the heating member 62 may comprise, for example, a heating resistor that allows the heating element to be heated. by conduction, convection and / or radiation (for example infrared, microwaves ...) the end 11 of the stick S. If necessary, the heating member 62 may also participate in the application of the product associated with the rod S and may for this purpose have an upper face 70 of suitable shape, for example beveled.
- the user can bring the end 11 of the stick to the heating member 62 and trigger the heating by pressing the control member 64.
- the heating device may comprise a light indicator 72 signaling to the user the operation of the heating member 62.
- the user can then interrupt the heating when he visually observes that the end 11 of the rod has changed in appearance due to the temperature rise, for example has become glossy.
- the user can then possibly, at this moment, move the end 11 a little more upwards so as to facilitate the application of the product, without contact with the heating member 62.
- the user can proceed to the application of the product with contact not only of the stick S but also of the heating member 62 on the lips or the skin.
- the surface of the heating member 62 that can contact the skin may be flocked or have a textured surface appearance facilitating application.
- the stick S passes through a heating member 62 defining an opening 76 of narrowed section relative to the body section of the stick.
- the softening of the rod S in contact with the heating member 62 may thus be accompanied, in this example, by a deformation of the rod through the heating member 62. This may increase the accuracy of application of the product. and to prevent the rod S can be advanced relative to the heater 62 until sufficient softening is achieved.
- FIG. 14 represents a variant embodiment in which the mass of product S associated with the stick S is supported by a rod 200, and is suitable for example for a single use.
- the application surface 202 is heated by being brought into contact with or near a hot surface, for example by introducing it into a housing provided with a heating means such as the housing previously described with reference to FIGS. 8 and 9.
- phase A In a skillet, the ingredients of phase A are added. The whole is stirred with a Rayneri while heating slightly at 50 ° C.
- the pigments of phase B are ground in a part of phase A.
- the ground material, the other part of phase A and the waxes of phase C and the pasty fatty substances of phase D are added.
- the mixture is heated to 98-100 ° C. C stirring with Rayneri until melting waxes.
- the charge (phase E) is added to the mixture, which is poured into a mold to make lipsticks with a diameter of 12.7 mm.
- the molds are then placed at -20 ° C. for half an hour, then the rods are demolded, which are mounted in lipstick mechanisms such as that illustrated in FIG. 8, for example.
- the lipstick has a dynamic coefficient of friction of 1.05 at 25 ° C. and a hardness at 20 ° C. of 146 Nm -1 .
- phase D The pigments of phase D are ground in phase A.
- phase E mother-of-pearl
- the hardness of the stick at 20 ° C. is 156 Nm -1 .
- the bevel of the composition is brought into contact with a hot source at 60 ° C. for 10 seconds and then applied to the lips:
- the application is more pleasant compared to the application performed at room temperature as described above, the deposit on the lips is shiny with good gloss and without migration.
- the invention is not limited to the examples that have just been illustrated.
- the displacement of the rod can be effected by means of a mechanism comprising at least two parts movable in rotation or a mechanism moving the rod in increments. Examples of such incremental mechanisms are found on hot melt glue guns for example, an example of which is given in US 2003 / 0,150,875 or US 2006 / 0,191,957.
- the heating resistor is integrated in the base part or in the closing cap thereof and is powered by an electrical source which is located on a housing with which the base part or the cover must be engaged to be electrically connected. This can prevent the incorporation in the base part or the cover of one or more batteries or accumulators.
- the base portion or the cover comprises at least one electric accumulator and it is recharged by placing the base part or the hood on a charging station.
- the heating of the end of the rod can still be obtained by a mechanical action of the user, for example by the rotational drive of a wheel mounted rotatably on the hood and which is in engagement with a wiper, so that that the rotation of the wheel causes the elevation of the temperature of the wiper, this temperature rise being transmitted via a contact piece at the end of the stick.
- the invention is not limited to a lipstick or a makeup or skin care product or lips.
- the product may be present on a pallet at the time of its warming.
