Abstract: A device for packaging a product, particularly a cosmetic product, and for dispensing it under pressure includes a container which, at least in part, is translucent or transparent. The container delimits two compartments separated from one another in a sealed fashion. A first compartment is in communication with a valve fitted to the device, and contains the product to be dispensed under pressure. A second compartment contains a propellant in the form of a liquefied gas. A retainer is provided inside the second compartment and is capable of trapping the liquid phase of the propellant, the retainer having at least one portion which is permeable to the gaseous phase of the propellant.

Abstract: A dispensing head for actuating a dispensing element associated with a container and for dispensing product from the container is provided. The dispensing head may comprise a body configured to be mounted on the container, with the body at least partly defining a feed channel. A movable element may also be provided having a portion defining a dispensing orifice. The movable element may be movable between a first position, in which the dispensing orifice is in fluid communication with the feed channel, and a second position, lacking this fluid communication with the feed channel. An elastic element may also be provided and configured to cause at least one of the portion of the movable element and a part of the body to be elastically biased against the other of the portion of the movable element and the part of the body when the movable element is in the first position.

Abstract: A fluid product dispenser and a dispensing head for a fluid product dispenser are provided. The fluid product dispenser dispenses fluid product in the form of any one of a jet and a spray. The dispensing head includes a body or first piece having an inlet conduit. The inlet conduit communicates with a stem of any one of a pump and valve of the fluid product dispenser. The dispensing head also includes a second piece mounted on the first piece. The first piece includes a dispensing orifice which can be detachably placed in communication with the inlet conduit. The second piece is movable at will, with respect to the body or first piece, in an X-direction, wherein the X-direction is different from a Y-direction defined as the fluid product outlet direction of the jet or spray of the fluid product. The second piece is movable in order to clean the inlet conduit.

Abstract: A swirling effect nozzle has substance feed channels opening out into a swirling chamber which communicates with an outlet orifice. The ratio Ap/Ao where Ap is the smallest total section offered by the channels to the passage of the substance and Ao is the section of the outlet orifice is less than or equal to 0.5.

Abstract: A dispenser (1) for a liquid product (P) containing a film-forming polymer in the form of fine droplets, includes a container (2) containing the product (P) and at least one propellant gas (G). A valve (15) for dispensing the product, mounted on the container (2), includes a body (24) provided with a first chamber (28a) and a second chamber (28b), intercommunicating via a passage (p), movable element (16) for actuating the valve (15) being provided for the dispensing of the product, the first chamber (28a) being provided with a first additional gas intake opening (d1), and a second opening (d2) for the intake of the product in permanent communication with this product, the second chamber (28b) at least partially formed of the actuating element (16). In this valve, the delivery rate during the dispensing of the product (P) is determined by the cross-section of the passage (p).

Abstract: A valve (1), particularly for an aerosol container, includes, inside a valve body (2), an inlet passage (4) communicating with the container and an outlet passage (10), a first elastic return (16) for urging the valve (1) into the closed position, and a regulator for regulating the product outlet flow rate, which includes a second elastic return (14) for supplying a set-point pressure for the regulator. The second elastic return (14) is arranged in a compartment (12) of the valve body (2) isolated from the product, the pressure inside the compartment (12) being equal to atmospheric pressure.

Abstract: An aerosol system for dispensing a hair lacquer having a flammability classification less than or equal to 4 according to the Roth apparatus comprises, in combination, an aerosol recipient provided with a value equipped with a dispenser wherein the valve and dispenser have orifices such that the initial outflow of the hair lacquer is between 0.5 and 0.7 g/s. The aerosol recipient contains a hair lacquer composition consisting of 12 to 25% by weight of water, 10 to 26% by weight of an alcoholic phase selected from the group consisting of ethanol, isopropanol and mixtures thereof, and 49 to 78% by weight of dimethyl ether, the alcoholic phase containing from 3 to 5% by weight, compared to the total weight of the composition, of a synthetic film-forming resin.
