摘要： A foam discharging nozzle of the invention is a foam discharging nozzle for a foam discharging device, including: a foam diffusion space to which foam produced by mixing a liquid and a gas is supplied from a foam supply opening located on an upper side; and at least one foam discharging opening formed in a bottom portion of the foam diffusion space. The area of the bottom portion of the foam diffusion space is wider than the area of the foam supply opening. The centroid of the foam discharging opening does not match the centroid of a supply opening projected portion formed by projecting the foam supply opening onto the bottom portion parallel to a central axis of the foam diffusion space.

摘要： 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.

摘要： A foam discharging device includes: a storage portion that stores a liquid agent; a foamer mechanism that changes the liquid agent into foam to generate a foam body; and a discharging portion that discharges the foam body. The discharging portion includes a foam passing chamber that allows the foam body to pass, and one or a plurality of ejection-port forming wall portions that extend downward below the foam passing chamber, are formed into a closed-loop shape in plan view, have the inner space communicating with the foam passing chamber, and have the lower edge having an ejection port formed thereon. At least part of the ejection-port forming wall portion has a bottom end portion formed into a shape that has a thickness reduced toward the lower side. The ejection-port forming wall portion and a second portion. The height position of a lower edge of the first portion is higher than the height position of a lower edge of the second portion.
