Patent 7621423 was granted and assigned to L'Oreal Alumni Official Association on November, 2009 by the United States Patent and Trademark Office.
A container for packaging a product includes a casing made of a first material, and at least one deform able part in contact with the product and made of a second material with a lesser rigidity than the first material. The container is configured so that a pressure exerted on the deformable part causes a deformation of the latter and a displacement of the product towards the opening of the container. The deformable part can return to its undeformed shape when the pressure is released.
