FIELD: process engineering. ^ SUBSTANCE: invention relates to foam dispenser and foamer. Proposed device comprises container for fluid and air that can be compressed manually, foam-forming assembly and valve body. Foam-forming assembly may be fitted either in or on container opening. It comprises casing with air and fluid channels. Each of said channels terminates in the neck and communicates with outlet channel terminating in outlet hole. At rest, valve body shuts off fluid channel mouth and air channel mouth to seal them, hence, to prevent fluid and air flows into outlet channel. For dispensing, said valve opens fluid and air channels mouths to allow mixing of air and fluid in outlet channel. Valve flexible body comprises arc-like section. Section passes into fluid channel mouth. Fluid pressure on valve body makes arc-like section add to sealing of fluid channel mouth. ^ EFFECT: simplified design, higher quality of foam. ^ 20 cl, 6 dwg |
