A static mixer suitable for mixing liquids, pastes, creams, gels or other fluids. Fluids introduced into a static mixing cavity of the static mixer are mechanically mixed by the static mixing cavity, and then dispensed from an outlet as a mixed fluid. The static mixer may be formed by two housing halves that are hingedly connected so that the static mixer can be easily opened for cleaning the static mixing cavity.

A system for treating the hair, to be connected to a water inlet, that includes at least one source of a cosmetic product, a water-dispensing device to convey the water to the hair, an adjustment device making it possible to inject, into the water, the product originating from the at least one source of product and to vary the content of product originating from this source in the water conveyed to the hair by the dispensing device and/or the amount of product conveyed to the hair by the dispensing device, this adjustment being able to assume at least one intermediate value between minimum and maximum content and/or amount values, a pressure booster to increase the pressure of the water at the inlet of the dispensing device beyond the pressure of the water at the inlet of the system.

A rinse-off hair treatment product with a multi-chamber tube package that can contain a dual-phase rinse-off hair treatment composition that can provide a warming sensation and hair conditioning. The multi-chamber tube package can be a tube-in-tube package with an outer tube with an outer chamber that contains a conditioning composition and an inner tube with an inner chamber that contains a warming composition. The inner chamber is fluidly connected to one or more central orifices by an inner nozzle channel and the outer channel is fluidly connected to one or more outer orifices by an outer channel. The ratio of the area of the central orifice(s) to the outer orifice(s) can be greater than 1. The ratios can help the product dispense as a single stream with two visible phases, which has been found to prompt the consumer to intuitively mix the composition, thereby activating a warming sensation.

Formulation delivery systems, formulation delivery devices, and formulation cartridges for the same are provided. Formulation delivery systems include a reusable handle, a formulation dispensing assembly, and a controller. The formulation dispensing assembly includes a reciprocating nozzle assembly and a pump. The reciprocating nozzle assembly is fluidically coupleable to the formulation cartridge or the cleaning cartridge received within the reusable handle. Formulation delivery devices include a reusable handle configured to receive a formulation cartridge therein, and a formulation dispensing assembly disposed in the reusable handle. The formulation dispensing assembly includes fluid conduits, a pump fluidically connected to the fluid conduits, a reciprocating nozzle assembly, and a controller. Formulation cartridges include a reusable cartridge body, a valve frame, and a disposable refill packet reversibly-coupleable to the reusable cartridge body. The disposable refill packet includes a formulation packet and a body portion configured for insertion into the reusable cartridge body.

The present invention relates to a cosmetic device comprising: a support and a composition, carried by the support, for dyeing or bleaching the hair, said composition having a formulation that varies depending on the position on the support, so as to allow shaded dyeing or bleaching to be produced on the hair by transfer.

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.

An apparatus for applying a two-component liquid composition to a surface has a housing having an open end, and a roller ball disposed and rotatably retained in the housing and projecting through the open end. There are two containers disposed at least partially in the housing. Each container has a dispensing nozzle arranged adjacent the roller ball. The nozzles have an open end such that a liquid or pasty substance disposed in each of the containers flows from the containers through the nozzle directly to the roller ball upon application of pressure to the substances in the containers. Rolling roller ball across a surface mixes the two substances on the roller ball with each other. This occurs by virtue of the movement of the roller ball around the surface, which causes the substances to flow around the ball and mix with each other during rolling.

A dispenser includes a first pouch configured to store a first component of a two component material, a second pouch, separate from the first pouch, and configured to store a second component of the two-component material, an outlet part having an outlet via which the first and second components stored in the first and second pouches are capable of being dispensed after the first and second components have been mixed in the outlet part, and a neck connected to the first and second pouches, a longitudinal axis of the dispenser extending in parallel to the outlet, and the first and second pouches being compressible towards one another in the direction of the longitudinal axis, the outlet part axially moveable relative to the first and second pouches in a direction towards the neck along the longitudinal axis.

An apparatus for applying a two-component liquid composition to a surface has a housing having an open end, an inner surface and an outer surface, an applicator retained in the housing and projecting through the open end, two containers removably mounted to the inner surface of the housing, each container having a dispensing nozzle extending through an aperture in the housing and arranged adjacent the applicator. A cover is mounted over the containers. There is a cutting device arranged on the housing adjacent the nozzles, the cutting device having at least one blade, wherein pressing the cutting device causes the blades to pierce the nozzles and allow contents of the containers to exit the containers and flow to the applicator.

The appliance includes a receptacle for hair formulation. A brushhead member is attached to the receptacle and is in fluid communication therewith, wherein color formulation in the receptacle is moved to the brushhead and the brushhead moved back and forth by a pump and motor mechanism. The receptacle and the brushhead are structurally sized and adapted for a singlue use and to be disposable thereafter.
