A formula delivery appliance generally includes a formula delivery head having features to mix, direct, and distribute formulation through nozzles to a desired location, such as the hair or scalp of a user. In this regard, the formula delivery head may include a plurality of nozzles configured to discharge the formulation at a desired flow rate. In some instances, the flow rate across the plurality of nozzles is controlled such that each nozzle has a flow rate within a specified percentage of the average flow rate across the plurality of nozzles.

A formulation delivery appliance can be used for treatment of the hair and scalp, such as an appliance used to color hair. The appliance may include a container having an aperture and being configured to retain a volume of formulation. The formulation delivery appliance may further include an elongate engagement element having a channel extending therethrough and being configured to be at least partially received by the aperture of the container when the container is mounted to the engagement element. A vent aperture is formed in the engagement element and provides fluid communication between the channel and an area outside of the engagement element when the container is disengaged from the engagement element. The vent aperture is sealed, and the channel receives a flow of formulation from the container when the container is mounted to the engagement element.

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).

Cosmetic applicators for applying a cosmetic to a body part of a person are disclosed. The cosmetic applicators include containers in which cosmetics of different colors are respectively contained. The applicators are constructed so that the cosmetics can either be applied together or to be applied individually.

The device for delivering a product to the base of hair shafts and/or on the scalp of a predefined user comprises a base comprising a container for the product, equipped with a filler cap, and an electric pump aspirating the product in the container and pushing it into a flexible tube (809). The device also comprises a case (800) connected to the flexible tube, a case whose geometry is configured to be held in the palm of a user's hand and comprising a row of assemblies (810) having a convex distal surface (805) of contact with the user's head, each of these assemblies comprising a tooth (803), at least one nozzle and at least one applicator. The convex distal surfaces of the assemblies are all tangential to a flat curve (818) whose radius of curvature is equal to a radius of curvature of the user's skull (820). The case also comprises a control button (808) for controlling the operation of the pump.

An application device for applying hair-coloring composition, comprising a device body, comprising a first reservoir comprising a first piston; the first reservoir configured to receive a first part of a hair-coloring composition; a second reservoir comprising a second piston; the second reservoir configured to receive a second part of a hair-coloring composition; and a dispensing mechanism associated with the first piston and with the second piston: the dispensing mechanism configured to sealingly move the first piston inside the first reservoir and the second piston inside the second reservoir; and an application cap, comprising a mixing mechanism; and a plurality of projecting tines: wherein the application cap is configured for reversible-connection with the device body such that, when the application cap is connected with the device body, the first reservoir and the second reservoir are sealed from the outside except channels of the plurality of projecting tines which are in fluid communication with the first reservoir and the second reservoir, through the mixing mechanism; and wherein the dispensing mechanism is configured, when activated, to move the first piston and the second piston towards the plurality of projecting tines thereby mixing the first part of the hair-coloring composition with the second part of the hair-coloring composition to form a mixed hair-coloring composition to be dispensed through the plurality of projecting tines.

A hair-penetrating shield 220 comprises a tooth array having top 280 and bottom 290 surfaces. In some embodiments, for a majority of the teeth, a cross section of each tooth (for example, triangular in shape) has an asymmetric width profile such that the tooth cross section, on average, is narrower near the top of the tooth and wider near the bottom of the tooth. In some embodiments, a ratio between: i) a first average tooth width describing the average tooth width below the top-bottom midpoint; and ii) a second average tooth width describing the average tooth width above the top-bottom midpoint is at least 1.2, or at least 1.6. In some embodiments, a non-viscous hair-coloring agent is dispensed as a mist over the top of the surface of the shield so as to color roots of hair passing through the spaces between the teeth of the user's hair. In some embodiments, closely-spaced teeth of the hair penetrating shield protect the user's scalp from the non-viscous hair-coloring agent. Related methods and kits are disclosed herein.

The scalp applicator comprises an applicator comb, a snapping cap, a solution container, and a pair of finger rests. The scalp applicator is configured for use with a liquid phase cosmetic media. The scalp applicator may be a tool that is adapted to apply the liquid phase cosmetic media to a scalp of a patient. The pair of finger rests may be adapted to be pulled by a user's fingers while a user holds the solution container. Pulling the pair of finger rests may activate a pump to force the liquid phase cosmetic media from the solution container through the applicator comb onto the scalp of the patient.
