Abstract (en)
A dispenser for pasty detergents includes a socket (A) for introducing a detergent container and a chamber (G) in communication with the socket (A) through a one-way detergent inlet valve and with the outside through a one-way outlet valve, a pressure and a vacuum being alternately created in said chamber (G) through a pump (P) provided with a return spring (S). Each of said one-way inlet and outlet valves consists of a membrane (M; V) made of an elastically deformable material and provided with a central bore, and of a corresponding conical shutter (N; Z) suitable to close said bore. The central portion of the membrane is thicker so as to have a greater rigidity, whereby in the closing return motion when it abuts against the conical surface of the shutter (N; Z) it cuts the residual film of detergent possibly remaining and achieves a perfect tightness without risk of dripping. <IMAGE>
