An application device for materials, in particular adhesives, including at least one cartridge receiving device for receiving a replaceable cartridge which contains a material and has a material outlet opening; a rotary device for metering or mixing the material, rotary device having a first engagement element; a drive device for driving the rotary device, the drive device having a rod which is mounted in a rotatable and axially movable manner and has a second engagement element at the end face; and a gearing unit for driving the rod in order to bring the first and the second engagement element into engagement with each other.

Methods, apparatus, devices and systems for mixing and dispensing multi-component materials. The mixing and dispensing may be performed using a mobile, enclosed dispenser that can be used to supply a mixed multi-component material at the point of use. In some embodiments, the components to be mixed into the multi-component material may be supplied in cartridges.

A matter displacement and mixing system having a mixing chamber for material to enter, and a vortex aperture that directs air into the mixing chamber at either a high velocity for violent shearing or lower velocity for gentle mixing. This would depend on the shape of the vortex aperture, or the pressure.

A portable dispensing system for dispensing a solution of a fluid and a solid product includes a fluid line, a dispenser, and a cartridge. The fluid line includes a first and second fluid line ends and a fluid source connection at the first fluid line end. The dispenser is at the second fluid line end. The dispenser includes a body and a fluid outlet. The cartridge houses the solid product and includes a fluid inlet and a solution outlet. The cartridge is removably connected at the fluid inlet to the fluid outlet of the dispenser. The cartridge is configured to receive fluid from the fluid outlet of the dispenser such that fluid contacts the solid product housed in the cartridge and dissolves at least a portion of the solid product forming the solution. The cartridge is also configured to output the solution at the solution outlet.

A mixer for a plural component spray gun is presented. The mixer has a mixer body comprising a mixing chamber with an outlet. The mixer also has a first fluid component inlet, coupled to a first fluid conduit, configured to introduce a first fluid component into the mixing chamber. The mixer also has a second fluid component inlet, coupled to a second fluid conduit, configured to introduce a second fluid component into the mixing chamber. The first and second fluid component inlets are offset with respect to a centerline of the mixing chamber and positioned such that a first fluid flow from the first inlet is directed toward the outlet, and a second fluid flow from the second inlet is directed toward the outlet.

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 re-mixing dispenser for containing and dispensing a liquid. The dispenser may have one or more tubes, each containing a different liquid. At least one of the liquids may be re-mixed in situ, using a special two-piece plunger and plunger rod. A mixing piece of the two-piece plunger is moveable independently of a top piece and has blades that allow it to move through the liquid. A plunger rod is removably attached to the mixing piece and is operable to move the mixing piece up and down within the tube during mixing. The two plunger pieces are joined and moved as a single plunger during dispensing.
