A doser for controlled release of a preferably liquid medium, such as a liquid detergent, comprising a container and a locking and dosage insert connected to the container. The container is provided with an inwardly directed flange part for forming a container opening, and the dosage insert comprises a flange-like counterpart which abuts the flange part of the container and forms an opening which extends into the container. The insert also includes a locking and dosage part which is adapted for arrangement of the insert in locking and insertion positions in the container opening. The insert includes a number of shovel-shaped blades connected to the inner rim of the counterpart via thin-walled hinge areas. The blades abut with their upper terminal surfaces the inner surface of the flange part of the container in a locked position and extend convergingly from said upper terminal surfaces into the inside of the container, where they are connected to a connection body via thin-walled hinge areas. A very secure and reliable connection between the insert and the container is obtained, since in its locked position the locking and dosage part of the insert presses the counterpart against the flange part of the container and is itself situated in the inside of the container so that it cannot from outside be forced to leave this locked position. The locking and dosage part causes a controlled release of detergent, since its shovel-shaped blades obstruct the inflow of water into the inside of the doser and the outflow of detergent from the doser. |
