Abstract: 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.

Abstract: A formula delivery system can be used in conjunction with hair and scalp treatment appliances to supply a hair treatment formulation to the appliance. In one aspect, the formula delivery system delivers hair coloring formulation to the appliance. Formula delivery systems of the present disclosure generally include at least one fluid container configured to retain a volume of formulation for delivery of the formulation to a hair coloring appliance. In this regard, the formula delivery system may be configured to removably couple to an inlet member of the appliance that allows the appliance to draw the formulation from the fluid container for use within the appliance.

Abstract: 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.

Abstract: Hair coloring appliances include an elongate handle and a consumable assembly removably couplable to the handle. The consumable assembly has a manifold chamber with a fluid inlet in selective fluid communication with a first formulation fluid source, a plurality of outlet nozzles configured to discharge a first formulation from the manifold chamber, and a distribution protrusion extending into the manifold chamber and configured to direct the flow of the first formulation from the fluid inlet to each of the plurality of outlet nozzles.

Abstract: A formula 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 consumable assembly incorporating various components of the hair and scalp treatment appliance, a portion of which may be consumed and then replaced by a user. In this regard, the consumable assembly may include one or more formulation delivery packets, nozzles, manifold chambers, distribution protrusions, and the like. The hair treatment appliance may also include a rotatable coupling having a driven gear and a drive gear, where the driven gear may selectively engage the drive gear. In another aspect, the hair treatment appliance may also include a fluid container to retain a volume of formulation for delivery to the appliance.

Abstract: Formula delivery devices include a handle and a consumable assembly. The handle has a handle shell, and the consumable assembly is configured to be removably joined with the handle by insertion into the handle shell. The consumable assembly has a formulation container disposed in an elongate housing and is configured to contain a volume of a formulation. The formulation container is provided with a sealing member configured to enable fluid communication with the formulation container.

Abstract: A drive shaft coupling is provided, such as a coupling used with a formula delivery appliance. The drive shaft coupling generally includes a drive gear and a driven gear, with one of the drive gear and driven gear having a biasing member to allow axial translation. The drive shaft coupling is generally configured to transfer rotation from the drive gear to the driven gear. In one aspect, the drive shaft coupling is capable of alignment and coupling of the drive gear and driven gear upon the radial sliding of the coupling from a non-engagement position to an engagement position.
