Packaging and applicator device

A packaging and applicator device for applying at least one cosmetic composition, the device comprising:

• a reservoir containing the composition to be dispensed;
• an applicator element including an applicator head that is secured to the reservoir at least during application, the head presenting an application face for coming into contact with the region to be treated, and including at least one cavity that opens out into the application face,
• wherein at least one of (a) the reservoir includes at least one extension that covers, at least in part, the applicator element or (b) the application face extends generally obliquely relative to a longitudinal axis of the reservoir;
• and
• at least one feed channel for supplying the composition to the application face;
• the applicator head including:
• at least one portion that is cantilevered-out as far as the periphery of the applicator head, and that defines the application face at least in part;
• wherein the cantilevered-out portion is flexibly mounted so as to make it possible to change the orientation of at least a portion of the application face when the application face makes contact with a surface.
