A foam-forming assembly includes a housing having an air passage and a liquid passage, each ending in a mouth and being in communication with a dispensing passage having a dispensing opening, and a valve body which, in a rest position, covers the mouth of the liquid passage and the mouth of the air passage in a sealing manner in order to prevent a flow from the liquid passage and the air passage to the dispensing passage. During dispensing, the valve body opens the mouth of the liquid passage and the mouth of the air passage in order to allow mixing of air and liquid to take place in the dispensing passage. The mouth of the air passage is substantially annular, and the air passage includes a pressure balance chamber to divide the air pressure substantially equally over the substantially annular mouth.

Foam-forming assembly and squeeze foamer

A dispensing assembly to dispense a foam, having: a liquid pump having a liquid inlet () and a liquid outlet (), an air pump having an air inlet () and an air outlet (), a mixing chamber (), wherein the air outlet and the liquid outlet are in fluid communication with the mixing chamber, a dispensing channel (). A first end of the dispensing channel is in fluid communication with the mixing chamber () and the second end forms a dispensing opening () for dispensing of foam. The dispensing channel () and the mixing chamber () are connected to each other via a constriction. The constriction is formed by an opening having a cross section which decreases towards the dispensing channel.

Foam dispensing assembly

A dispensing system includes a pump mechanism that has a liquid chamber, a liquid piston for delivering fluid to a mixing chamber, and a valve component biased to close the outlet from the liquid chamber. The pump mechanism also has an air chamber, and an air piston for delivering air to the mixing chamber. A bore allows passage of a mixture of the air and the liquid from the mixing chamber to a dispensing tube. A pump actuator moves the air piston and the liquid piston to propel a dose of the mixture of the air and the liquid through the bore and into the dispensing tube and to collapse a draw-back chamber. The draw-back chamber expands to draw the mixture of the air and the liquid from the dispensing tube into the draw-back chamber. The valve component is biased to close the first outlet before the draw-back chamber expands.
