#CMT# #/CMT# A foam-forming assembly has a housing with an air passage and a liquid passage that communicate with a dispensing passage, which ends in the opening (3) of a container (2) that stores liquid and air. A valve (6) covers both liquid and air passages to prevent flow of liquid and air in the dispensing passage during rest state, and opens both liquid and air passages to allow mixing of air and liquid in the dispensing passage during dispensing state. The mouths (10,12) of both air passage and liquid passage are substantially annular and concentrically arranged with respect to one another. #CMT# : #/CMT# An independent claim is also included for a foam-forming assembly. #CMT#USE : #/CMT# For pumpless squeeze foamer (claimed). #CMT#ADVANTAGE : #/CMT# Prevents reduction in the quality of foam by improving mixture between liquid and air stream through the concentrically arranged mouths of air passage and liquid passage. Simplifies structure of the device by eliminating complicated flow paths. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the cross sectional view of the dispensing device. 2 : Container 3 : Opening 6 : Valve 10,12 : Mouths. |
