Abstract:
The present invention relates to a foam dispensing apparatus including a nozzle portion that mixes a liquid with gas so as to dispense the liquid in a form of a foam. The nozzle portion includes: a foam generation mechanism including a gas liquid mixing portion in which the liquid and the gas are mixed and a first porous body that is disposed downstream of the gas liquid mixing portion; a cavity that is located below the first porous body and whose cross-sectional area defined by a plane perpendicular to a foam dispensing direction T is larger than the area of the first porous body; and a foam dispensing outlet that dispenses foam that has passed through the cavity to an outside. The foam dispensing outlet is configured so as to form shaped foam having a predetermined shape, and an opening area of the foam dispensing outlet that is on the cavity side is smaller than the cross-sectional area of the cavity.
