The container comprises a bowl having a side wall 12, the upper edge of which forms an opening over which an elastomeric membrane is secured. An actuator disc is secured to the upper surface of the membrane. Manual pressure on the membrane causes expulsion of fluid through outlet port 31, and the resilience of the membrane reduces the pressure in the container to draw fluid in through inlet port 30.
