Abstract
A dosing head for dispensing a fluid from a container is presented. The dosing head has an inlet opening connected to the container, an outlet opening connected to the inlet opening via a conduit, a pump provided in the conduit, and a aerating opening. The dosing head can be used in an upside down position. A liquid seal is arranged between the aerating opening and the container. The seal can include an aerating channel that is rotated twice through about 180° and which can be assembled from two mutually connected parts. The liquid seal can have a restriction which prevents liquid form reaching the aerating opening when upside down.
