Abstract
An apparatus for dispensing a semifluid medium such as a pasty mass, cream, gel or the like, from a container comprises a manually operated dosing pump connected to the container. The dosing pump itself comprises a pump body which is attached to a rim of the container opening and defines a pump chamber, the volume of which can be changed from outside. The pump chamber communicates on its input side with the interior of the container by way of a non-return valve that opens in the direction of the pump chamber and on its output side with the exterior by way of a delivery outlet. The container is also provided in its interior with a flexible bag for holding the semifluid medium. The bag is connected to the container in the region of the container opening.
