  • cosmetic product is understood to mean any product as defined in Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.
  • the packaging and application assembly is intended more particularly for the application of a cosmetic product to a human keratin surface, such as the skin, the lips or the nails.
  • an assembly for packaging and applying a cosmetic product comprises, on the one hand, a body forming a reservoir which is intended to contain the cosmetic product to be applied and, on the other hand, an applicator comprising an application member that defines an application surface intended to come into contact with a body surface of the user.
  • Packaging and application assemblies are known that aim to improve the spreading of the product, while facilitating the application thereof.
  • the Juicy Shaker® lip oil product sold by Lancome with a pointed-shaped flexible applicator is known.
  • the two- phase lip oil is shaken in the bottle. It then passes through a screen having a shape complementary to that of the applicator and that is pierced by an opening at its top, before impregnating an applicator made of porous material.
  • the user pinches the tip of the applicator, highly impregnated with lip oil, between his/her lips until the desired coverage and uniformity is obtained.
  • the present invention aims to achieve all or some of these objectives and for this purpose proposes a device for packaging and applying at least one cosmetic product comprising a container containing a product to be applied, an applicator of longitudinal axis X comprising a gripping portion and an application member, and a separating element positioned between the container and the applicator, the separating element comprising a bottom wall that delimits a housing suitable for at least partially receiving the application member and having at least one through-opening, the application member being movable relative to the gripping portion and the application member being mounted movably in rotation about an axis of rotation Y.
