A removable hygienic hand pump adapter or adapter mechanism for dispensing liquids or semi-liquids from a container comprises a body having a bore and of a shape to fit around a container with a neck. A hand pump on the body includes a manually flexible outer wall defining an air chamber. A cover assembly upon the body has a cap portion snugly positioned over the neck and has an outlet. An extension tube which is integral with the cap portion extends into the container. A flexible collapsed bladder is mounted at its neck around the tube, extends along the tube and is adapted to expand along the interior of the container upon application of pressurized air from the pump to progressively dispense all the contents of the container.
