Dispenser for small quantities of cleaning solution - has tubes leading from reservoir closed by mushroom-shaped elastic valves

摘要

The dispenser for a small quantity of liquid is particularly for a cleaning solution, such as liquid soap. It has a reservoir (1) of liquid (2) which is connected to a deformable chamber (12) by tubes (11,14) closed by a valve (16). The valves are mushroom-shaped elastic pieces (16,21) with a wide deformable head (18,22). This can be compressed to allow the liquid to pass when a sufficient differential pressure is applied to one side of the head and returns to its expanded position when no pressure is applied.
