This invention provides an airtight cosmetic container, which comprises a cover (2), a base (1), and a hollow gasket (10) positioned on the cover or the base. As the cover is moved into the closed position, the gasket (10) deforms to a point where the gasket sealingly engages the cover and the base. The gasket surrounds a volatile solvent- containing product, and because the gasket deforms between the cover and the base, a seal is obtained which substantially prevents the loss of the volatile solvent from the product when the container is closed.
L'invention concerne un boîtier de produit cosmétique étanche à l'air. Ce boîtier comprend un couvercle (2), une base (1) et un joint d'étanchéité creux (10) positionné sur le couvercle ou sur la base. Lorsque le couvercle est déplacé en position fermée, le joint d'étanchéité (10) se déforme jusqu'à se mettre en prise, de manière à assurer une étanchéité, avec le couvercle et la base. Ce joint d'étanchéité entoure un produit à base de solvant volatile. La déformation du joint d'étanchéité entre le couvercle et la base permet d'obtenir une étanchéité qui empêche sensiblement toute perte de solvant volatile à partir du produit lorsque le boîtier est fermé.
