Abstract
The invention relates to a foam-forming assembly for forming a foam, comprising a housing having an air passage and a liquid passage which each end in a mouth and which are in communication with a dispensing passage which ends in a dispensing opening, and a valve body. The invention is characterized in that the mouth of the liquid passage is annular and the mouth of the air passage and an entry port of the dispensing passage are substantially provided on the circumference of an imaginary circle, in which between the annular mouth of the liquid passage and the mouth of the air passage and/or the entry port of the dispensing passage an annular sealing surface is provided, against which, in rest position, the valve body sealingly engages, and in which during dispensing the valve body becomes detached of the sealing surface such that the mouth of the air passage, the mouth of the liquid passage and the entry port of the dispensing passage substantially simultaneously come in fluid communication with each other.
