摘要： A device for dispensing metered quantities of fluid from a container. The device comprises a through-flow passageway in which is arranged a valve chamber. A lower valve seat and an upper valve seat delimit said valve chamber. The valve seats are parts of two valve portions and may be closed by a lower and an upper valve body. A pressurizing bulb is arranged to generate a vacuum or excess pressure in the valve chamber. The device operates in the following manner. When the pressurizing bulb is compressed, soap solution is forced through the lower valve seat while the upper valve seat remains closed. When the pressure on the bulb is released, the bulb resumes its original shape and the vacuum thus created draws in fluid through the upper valve seat while the lower seat remains closed.
