An application device for a cosmetic product comprising a holding member, an application member having a surface for application of the product, and a heating electric element. The heating electric element is formed of at least one resistor mounted on a printed circuit positioned, at least in part, facing or in contact with the application member, and the surface area of the orthogonal projection of the resistor on a plane defined by the printed circuit is less than or equal to 10 mm.

Heating application device for a cosmetic product

A packaging and application device for a cosmetic product includes a receptacle for packaging the cosmetic product that has an outlet orifice, an application member having a plate forming an application surface for the product, a tube extending from the face of the plate opposite to the application surface to the receptacle so as to define a delivery duct leading on the one hand to the application surface and on the other hand into the receptacle, and an electrical heating element. The electrical heating element is a heating resistive wire mounted at least partly around the tube defining the delivery duct.

The present invention relates to an applicator for applying a composition to the human body, the applicator comprising: a support that is configured to be mounted in removable manner on an appliance that enables movement to be transmitted to said support; a reservoir that is secured to the support and that contains the composition, the reservoir being defined, at least in part, by at least one closure element; an applicator element that is secured to the support at least during use; and an opener element that is suitable for acting on the closure element in order to put the reservoir and the applicator element into communication.

Applicator and a kit including such an applicator

A device for loading and applying a cosmetic composition may comprise an applicator comprising an electric heater member, a container containing the composition, the container comprising a housing configured to receive at least part of the applicator so as to load the applicator with the composition, and an electrical circuit configured to power the heater member. The circuit may be configured so that the power supply to the heater member is automatically modified, leading to an increase in the electric power that is dissipated by the heater member when said heater member is received in the housing, when a predefined condition relating to the at least part of the applicator being received in the housing is satisfied.

Device for loading and applying a cosmetic composition

A generator for exciting a piezoelectric transducer, includes at least one digital processor unit. The digital processor unit is configured to operate at least in an iterative operation stage including more than two successive iterations. Each iteration includes: exciting the transducer at a plurality of frequencies in a frequency band about a set-point frequency; during transducer excitation, acquiring one or more values related to at least one electrical magnitude associated with the excitation of the transducer for a plurality of frequencies in the frequency band; and analyzing the values acquired to determine a new set-point frequency for a subsequent iteration.
