| 摘要 |
The invention relates generally to a foam dispenser having a reservoir (10), a housing (104), and a chamber (107). The reservoir (10) delivers fluid to the housing (104) and the chamber (107) through a dip-tube (106). The chamber (107) moves within the housing in response to fluid pressure or air pressure from the reservoir (10), allowing air and foamable liquid to enter the chamber (107). Foam-producing packing material inside the chamber (107) causes the air and foamable liquid to mix and produce foam.
