A technical objective of the present invention is to provide a chemical dispersion prevention mechanism for hair treatment, whereby chemicals used during the treatment of a hairstyle, such as a perm or hair dyeing, or foreign substances may be prevented from splattering onto an operator or a subject to be treated. To this end, the chemical dispersion prevention mechanism for hair treatment of the present invention is a chemical dispersion prevention mechanism for hair treatment, used by an operator, and comprises: a cover part for covering a hand or a portion surrounding same of an operator; and a wearing part enabling the cover part to be removably worn on the hand of the operator.

A hair coloring appliance includes a handle and a hair color delivery system supported within the handle. A nozzle assembly is adapted to receive hair color. The nozzle assembly includes a stationary frame and a nozzle array through which the hair color is delivered to the hair and a plurality of filaments adjacent the nozzles which are longer than the nozzles, acting as a stand-off between the nozzles and the scalp. A motor reciprocates the nozzle array back and forth as hair color moves through the nozzles.

A device (10) for packaging at least one product and dispensing at least said product on a surface is provided, which comprises at least one container (12) delimiting a product cavity (22) containing said at least one product and a dispensing member (14) mounted on said container (12). The dispensing member (14) has a first dispensing orifice (24b) in flow communication with the product cavity (22), said container (12) has a neck (18) allowing access to the product cavity (22), said dispensing member (14) comprises a dispensing duct (24) in flow communication with the product cavity (22). An assembly skirt (30) radially surrounds said dispensing duct (24), and an annular sealing lip (32) is radially disposed between said dispensing duct (24) and said assembly skirt (30), said annular sealing lip (32) bears radially against a sealing portion (18c) of the neck (18) of the container (12). Said sealing portion (18c) is located axially away from an opened end of the neck (18).

Device (10) for packaging at least one product and dispensing at least said product on a surface and comprising at least one container (14) delimiting a product cavity (24a) containing said at least one product and having a dispensing closure (26) designed to be separated from the container (14) for first use of said device in order to open a first dispensing orifice (24b) in flow communication with the product cavity (24a). Said device comprises an application member (40) mounted on the at least one container (14) having at least two rows (44b, 44d) of elastically deformable application teeth (44) arranged on both side of the dispensing closure (26) and extending outwardly from said at least one container (14), said application teeth (44) being each inclined towards the longitudinal axis (X-X′) of the first dispensing orifice (24b), and at least a plurality of teeth of the said rows (44b, 44d) of teeth are deformed in a stressed position by the contact with the dispensing closure (26) and configured to return elastically in a rest position when the dispensing closure (26) is removed, in said rest position, the teeth are more inclined towards the longitudinal axis (X-X′) of the first dispensing orifice (24b) then in the stressed position.

An apparatus for dispensing a fluid from a source of fluid comprises a roller and a tray member. The tray member comprises a pair of spaced walls having a contiguous tapered inner surface for defining an arcuate recess in an outer surface of the tray member, the outer surface tapering to an outer edge of each wall. Roller mounting means includes a pair of resilient spaced arms, each one of the arms spanning between and interconnecting the ends of the spaced wall. The tray member defines a pair ports spaced along a central longitudinal axis of the tray member for providing fluid communication between the source of fluid and the tray member. The roller is rotatably mounted to the spaced arms for receiving fluid from the tray member and applying the fluid onto a surface.

The present invention relates to an aerosol device including: —a container containing: —one or more propellants, and--a composition including one or more sebum-absorbing powders with a sebum uptake of greater than or equal to 35 m1/100 g, the propellant(s) possibly being present in the composition or, in the container, separate from the composition, —an aerosol device for dispensing the said aerosol composition, including a diffuser equipped with at least two, and better three, spray orifices (22). The invention also relates to a process for the dry-washing and cosmetic treatment of keratin materials, including a step of applying to the hair the cosmetic composition, sprayed from the particular aerosol device.
