A mixer (46) for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mixer includes a contoured seal head (120) that is configured to interface with a contoured chamber within a receiver to form a fluid-tight seal therebetween. The mixer receives individual component materials through inlet bores (50a, 50b) formed through the mixer. The component materials mix within a mix bore (52) of the mixer to form a plural component material that is emitted as a spray from an orifice (54) formed in the mixer.

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.

The present invention provides a foam dispenser having a twice automatic cleaning function that automatically discharges a compressed air toward a mixing chamber, when releasing a pulled trigger lever, thereby improving convenience of work and providing economic advantages. The foam dispenser having a twice automatic cleaning function includes a main body 4 including a hose connection unit 34 and an air hose connector 42, a coupling end part formed at the other end thereof, a pair of fluid passageways 20, an air passageway 22, and a handle 3; a dispensing nozzle 6 connected to the coupling end part of the main body 4, has a mixing chamber 64; a separate-fluid supply unit 8 provided inside the main body 4 to open or close the fluid passageways 20; and an automatic cleaner 10 provided at a middle portion of the air passageway 22 to automatically open the air passageway 22.

A cartridge is provided having at least one reception chamber (2), which extends in the longitudinal direction, for a medium to be dispensed, having an end face (4) and a cartridge wall (3) which bound the reception chamber (2) and which are injection molded in one piece, with the end face (4) having an outlet for the medium, and with the cartridge wall (3) having a first film (6) at its inner side bounding the reception chamber (2) which extends over the total cartridge wall (3) and is non-releasably connected to the cartridge wall (3). A method of manufacturing such a cartridge as well as a multicomponent cartridge are furthermore provided by the invention.

A dispenser comprises a housing defining at least three feed channels, a spool valve with a spool defining at least three flow passages, a deformable sealing plug in at least two of the feed channels and in sealing orientation with both the housing and the spool, and a nipple in at least the two feed channels of the housing comprising sealing plugs; wherein the spool can reversibly rotate between an open orientation and a closed orientation can dispense two-component form formulations that are free of gaseous blowing agents.

A foam spray gun is illustrated in which a third hose is attached to the gun for the application of either a liquid or a gas.

Multi-component fluid mixing devices and methods of manufacturing and using such multi-component fluid mixing devices are provided. The multi-component fluid mixing devices include one or both of a serpentine flow path and an attachment point decoupled from an inlet of the multi-component fluid mixing devices. The method of use includes switching between multi-component fluid mixing devices with different length flow paths, while retaining a constant position of the outlet of the multi-component fluid mixing devices. A manufacturing method includes fusing two halves of a multi-component fluid mixing device together with mixing elements in a serpentine flow path captured in a mixer wall formed between the two halves of the multi-component fluid mixing device.
