| 摘要 |
The invention relates to a dispensing device, and to a dispensing head (6) and the use thereof. By pressing down on the dispensing head, an associated dispensing valve (4) is opened, and the product (2) to be dispensed can flow out and/or can be discharged by way of a discharge chamber (9) and a downstream dispensing valve. In order to avoid, or at least minimize, post dripping or foaming, the volume of the discharge chamber is initially reduced when the dispensing head is actuated, and once the actuation is finished, particularly after the dispensing valve is closed, is enlarged again so that the product is suctioned from the outlet, that is, the dispensing valve, back into the discharge chamber. |
