FOAM-FORMING ASSEMBLY AND SQUEEZE FOAMER

摘要

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.

主权项

1. A foam-forming assembly, comprising:
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 having a rest position, in which the valve body 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, the valve body further having a dispensing position, in which 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, wherein the air passage comprises an air inlet to connect an air inlet tube, wherein the air inlet is arranged non-concentrically with the substantially annular mouth of the air passage, and wherein the mouth of the air passage is substantially annular, and wherein the air passage comprises a pressure balance chamber to divide the air pressure substantially equally over the substantially annular mouth so as to compensate for the non-concentrical arrangement of the air inlet.
