ABSTRACT:
One disadvantage during delivery of products such as foams, for instance shaving foam or gel, self-foaming products and other products that are applied with a pressurized system from a conventional, pressurized dispenser container with the aid of known dispenser heads that can be inserted into the delivery valve of the dispenser container is that the pressurized product remaining in the delivery channel continues to be pressed out in small amounts in an uncontrolled manner after utilization despite the fact that the delivery valve is closed. In order to eliminate said disadvantage, the dispenser head (1) is configured with an additional closing device (1′) that automatically opens the delivery hole (3) and automatically closes it after the dispensing process is completed.
