Definitions

• Cosmetic product dispensing head intended to be mounted on a receptacle, associated dispensing device and method
• the present invention relates to a cosmetic product dispensing head, intended to be mounted on a receptacle, comprising:
• the nozzle comprising an upstream part extending along an upstream axis, the upstream part being intended to be connected to the dispensing member, and a downstream part for guiding the product out,
• a push-button movably mounted between an idle position and a product dispensing position via the nozzle.
• This head is intended to be mounted on a receptacle containing a cosmetic product, in order to dispense the product in spray or aerosol form.
• the head is intended to selectively enable or disable dispensing of the product.
• the cosmetic product is, for example, a gel, cream or powder.
• Cosmetic product means in particular, in the sense of this invention, a product such as defined in EC Regulation no. 1223/2009 of the European Parliament and of the Council of November 30, 2009 relating to cosmetic products.
• the cosmetic product will be applied onto a surface of a user's body, such as the user's skin or keratin fibers.
• the head is generally mounted on a receptacle comprising, at the upper end thereof, a product dispensing member such as a valve or pump.
• a product dispensing member such as a valve or pump.
• the band on the head, covered by the push-button is engaged about the neck of the receptacle, and the dispensing nozzle is positioned in contact with the dispensing member.
• Moving the push-button from an idle position to a dispensing position causes the product to be dispensed.

Indeed, the nozzle is frequently blocked at the interface thereof with air, since the formula is not diluted with a dissolved gas and the dry solid polymer concentration is high. Moreover, in some cases, a small spray of formula is liable to form after closing the valve, given that the pressure in the dead volumes in the head falls, as the compressed gas escapes.
• One aim of the invention is thus that of providing a device eliminating any blockage of the nozzle orifice and minimizing the leakage of formula after filling.
