Abstract
Apparatus for dispensing a semifluid medium, in particular a pasty mass such as cream, gel or the like, comprises a container with a dispensing valve. The dispensing valve comprises a delivery tube that can be displaced, for example into the interior of the container and/or tilted about its long axis, against the action of a resilient means such as a spring. The delivery tube is coupled to an actuator defining an annular channel in such a way that the annular channel is in fluid communication with the delivery tube. The annular channel is closed by an annular closure flap which when opened under the pressure of the medium contained in the container defines an annular gap through which the medium can be discharged.
