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

The invention provides a dispensing assembly to dispense a foam, comprising: &#x22c5;&#x2014;a double cylinder element () mounted or to be mounted in an opening of a container (), comprising a liquid cylinder () and an air cylinder (), wherein the liquid cylinder has a smaller diameter than the air cylinder, and wherein the liquid cylinder and the air cylinder are arranged substantially concentrically, and &#x22c5;&#x2014;a piston assembly () comprising a liquid piston () and an air piston () for reciprocal movements in the liquid cylinder and air cylinder, respectively, and a common operating part for operating the liquid piston and air piston, &#x22c5; wherein a liquid pump chamber () is at least delimited by the liquid cylinder and the liquid piston, said liquid pump chamber having a liquid inlet () and a liquid outlet (), &#x22c5; wherein an air pump chamber () is at least delimited by the air cylinder, the air piston and the liquid piston, said air pump chamber having an air inlet () and an air outlet (), &#x22c5; wherein the piston assembly () further comprises a dispensing channel () in fluid communication with the liquid outlet and the air outlet, wherein the dispensing channel ends in a dispensing opening (), &#x22c5; characterized in that the air outlet () is provided in the liquid piston in a region of the air pump chamber opposite to the air piston ().

Foam dispensing assembly

The invention relates to a system for dispensing a foam of a fluid product (P) comprising a head () wherein a mixing chamber () of said product with air (A) is formed, said head having: a passage for product () and a passage for air (); a unit for foaming (); a supply valve () of the mixing chamber () which comprises a product valve () and an air valve (); a passage for return air () which is provided with an air return valve (); the supply valve comprising a membrane () whereon the product () and air () valves are formed, said membrane being arranged in order to be reversibly mobile starting at a pressure that the source of product () or that the source of air () exerts on it, between a stable position wherein the passages of the product () and of the air () are closed by the intermediary of the corresponding valve () and a stressed position wherein the passages for product () and for air () are open in order to supply the mixing chamber ().

System for dispensing a foam of a fluid product

The present invention provides a foam dispensing assembly comprising a liquid piston pump, comprising a liquid cylinder and a liquid piston delimiting a liquid pump chamber, and a liquid inlet and outlet, an air piston pump comprising an air cylinder and an air piston delimiting an air pump chamber, and an air inlet and outlet, a common actuation button for actuation of said liquid pump and said air pump, a dispensing channel for mixing and dispensing liquid and air pumped by said liquid and air pump, respectively, and a securing collar for attachment of said dispensing assembly to a container. The invention is characterized in that said air cylinder is formed by a cylindrical skirt of said actuation button, and said air piston is at least partially formed by a cylindrical extension of said securing collar and in that said air chamber at least partially surrounds said liquid chamber.

The present invention relates to a dispensing device comprising: &#x2014;a container () for holding a liquid having an opening, and&#x2014;a dispensing assembly () mountable on or in said opening, said dispensing assembly comprising: &#x2014;a pump () having a pump chamber () and a pump inlet () comprising an inlet valve () and a pump outlet () comprising an outlet valve (), and&#x2014;a liquid supply channel (), one end of said channel () being in fluid communication with said inlet (), the other end being arranged in a bottom portion of said container (), wherein a one-way valve () is arranged in said channel (), and wherein an air inlet opening () is provided between said inlet valve () and said one-way valve.
