A foamer mechanism (20) of a foam dispensing container has a gas-liquid contact chamber (21), a liquid agent flow passage (22) through which a liquid agent supplied from a liquid agent supply portion (28) to the gas-liquid contact chamber (21) passes, and a gas flow passage (23) through which a gas supplied from a gas supply portion (29) to the gas-liquid contact chamber (21) passes. The gas flow passage (23) has a gas opening (23a) that is open to the gas-liquid contact chamber (21). The liquid agent flow passage (22) branches into plural branch flow passages (for example, branches into a first branch flow passage (221) and plural second branch flow passages (222)). Each of the plural branch flow passages has a liquid agent opening (22a, 22b) that is open to the gas-liquid contact chamber (21). The liquid agent openings (22a, 22b) are respectively arranged at positions on the both sides sandwiching an extension region (26) of an adjacent flow passage (231) which is a part of the gas flow passage (23) adjacent to the gas opening (23a).

The present foam dispensing unit comprises a manifold defining a first channel and a second channel. The first channel defines an input for receiving a first liquid and an output for directing the first liquid into a mixing nozzle. The second channel defines an input for receiving a second liquid, and an output for directing the second liquid into the mixing nozzle. The foam dispensing unit further comprises a first flow adjustment mechanism positioned along the first channel for controlling a flow of the first liquid at the output of the first channel, and a second flow adjustment mechanism positioned along the second channel for controlling a flow of the second liquid at the output of the second channel.

An aerated wax application assembly comprises a meltable wax applicator, one or more meltable wax delivery conduits having a first end coupled to the meltable wax inlet of the meltable wax applicator and a second end positioned proximate a meltable wax holding tank, and an air injection system positioned upstream from the meltable wax applicator and configured to inject air into the meltable wax and generate the aerated meltable wax upstream of the inlet of the meltable wax applicator. A method of applying an aerated meltable wax onto an object comprises injecting air into a meltable wax such that it forms an aerated meltable wax, delivering the aerated wax through one or more meltable wax delivery conduits to a meltable wax applicator, and contacting at least one exposed surface of the object with the aerated wax when dispensing the aerated meltable wax from an outlet of the meltable wax applicator.

A dispensing system includes an above-deck nozzle portion, a reservoir for holding fluid, a foam pump, a multi-lumen dispense passage, and a mixing portion. The above-deck nozzle portion has a dispenser outlet and is disposed above a counter. The foam pump is disposed below the counter and includes at least one liquid pump chamber in fluid communication with the reservoir, at least one air pump chamber, and a pump outlet. The multi-lumen dispense passage includes an inlet, an outlet, at least one liquid lumen, and at least two air lumens. The inlet is in fluid communication with the pump outlet, the outlet is in fluid communication with the dispenser outlet, and the at least one liquid lumen and the at least two air lumens are each in fluid communication with the inlet and the outlet of the multi-lumen dispense passage. The mixing portion is disposed between the multi-lumen dispense passage and the dispenser outlet.

A crossover prevention valve for use in a multi-component fluid mixing and dispensing system includes a valve body defining at least two fluid passageways having respective one-way check valves at their outlet ends. A forward end of the valve body cooperates with an interior surface of a dispensing nozzle to define a mixing chamber for chemically reactive fluids prior to discharging the mixed fluids out of the dispensing nozzle. The crossover prevention valve does not permit reverse flow, thereby preventing clogs due to undesired intrusion of one reactant into the flow path of another reactant. Solidified reactants left in the mixing chamber are easily removed from the valve body, permitting the valve body to be reused even after sitting for extended periods.

One or more techniques and/or systems are disclosed for a foam fluid dispensing device that allows for quick and easy adjustment between a straight stream and dispersed stream. A user can quickly adjust between various stream patterns using a common motion in nozzle operation. An example device can comprise a nozzle comprising a nozzle body and an inlet configured to receive a flow of fluid, with a nozzle stem centrally disposed in the nozzle and fixedly engaged with the nozzle body. The device can also comprise a foam tube configured to receive and dispense at least a portion of the flow of fluid from the nozzle, with a foam tube coupler fixedly engaged with the foam tube. The foam tube coupler can be configured to operably couple with the nozzle stem.

A slurry arm is provided. The slurry arm includes: an arm body; a slurry line that extends through the arm body; an oxygen removal chamber provided in the arm body and configured to receive slurry from the slurry line; a purge gas supplier configured to supply a purge gas to the slurry in the oxygen removal chamber; and a main valve configured to selectively discharge gas from the oxygen removal chamber.

A dispensing system includes an above-deck nozzle portion, a reservoir for holding fluid, a foam pump, a multi-lumen dispense passage, and a mixing portion. The above-deck nozzle portion has a dispenser outlet and is disposed above a counter. The foam pump is disposed below the counter and includes at least one liquid pump chamber in fluid communication with the reservoir, at least one air pump chamber, and a pump outlet. The multi-lumen dispense passage includes an inlet, an outlet, at least one liquid lumen, and at least two air lumens. The inlet is in fluid communication with the pump outlet, the outlet is in fluid communication with the dispenser outlet, and the at least one liquid lumen and the at least two air lumens are each in fluid communication with the inlet and the outlet of the multi-lumen dispense passage. The mixing portion is disposed between the multi-lumen dispense passage and the dispenser outlet.

The present disclosure is a foam machine which is convenient to use, triggers foam generation and extrusion by a sensor, and effectively avoids cross infection caused by hands making contact with the machine.

A metering and application system for a moisture-curing polymer material includes a reservoir for the polymer material and a first pump and a second pump, wherein the polymer material is conveyable by the first pump from the reservoir to the second pump. In addition, a gas metering device with a defined pressure ratio is provided to bring a gas to a defined pressure, wherein the gas metering device is connected to the input of the second pump on its outlet side. In addition, a mixer for mixing the polymer material and the gas and a valve arranged downstream of the mixer for metering and a nozzle for applying the polymer material/gas mixture are provided.
