The present invention relates to devices for packaging and applying a substance, in particular a cosmetic or a care product.
German patent application DE 31 00529 A1 describes a device for packaging and dispensing a cream, the device comprising two portions that can turn relative to each other, and a chamber containing the cream, which chamber is formed inside the device, with turning of one of the parts relative to the other causing the volume of said chamber to decrease and the cream to be dispensed directly via an outlet orifice. That device does not have an applicator device.
U.S. Pat. No. 3,085,281 discloses a receptacle for nail varnish including a bladed stirrer that can be rotated by the user using a knurled wheel at the bottom of the receptacle.
European patent application EP 1 177 741-A1 describes a receptacle including a stirrer that can be driven in rotation by the stem of the applicator.
French patent FR 1 374 719 describes a similar receptacle.
US patent application No. 2002/0007839 describes a packaging and applicator device having a piston engaged on a screw that is turned by the user. The pressure exerted on the substance is due to the piston moving axially, which piston needs to be prevented from turning relative to the body of the receptacle in order to be capable of being driven by the screw.
Packaging and applicator devices for mascara are also known that comprise an applicator comprising a brush mounted at the end of a stem whose other end is secured to a closure capsule for the receptacle that also constitutes a handle. The receptacle is generally elongate in shape and relatively narrow, so that the brush can extract most of the substance that is contained in the receptacle. With such a device, a certain quantity of substance is nevertheless never extracted by the brush and becomes lost after a chimney has been formed in the substance.
