Methods of priming formulation delivery devices include providing a formulation cartridge, inserting the formulation cartridge into a handle of the formulation delivery device, and initiating a priming sequence which simultaneously pumps a first formulation and a second formulation from the formulation cartridge for a first time period such that the first formulation and the second formulation pass from the formulation cartridge, through a pump, and exit a nozzle assembly of the formulation delivery device.

Formulation delivery priming methods

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.

Reusable cartridge systems, devices, and methods

A valve system comprises: a valve body; a valve cap; and a valve plug between the valve body and valve cap is compressed radially and axially, and a central bore extends wholly through the valve body and valve cap and partially through the valve plug. The valve system is welded to a packet which can contain a hair color formula. One or more of the packets are then used in a cartridge compatible with a dispensing device.
