摘要

The device has a feeding chamber (118) that is provided for receiving the liquid to be dispensed (128). A dosing element (132) is formed in a base housing (110). An opening (134) is formed between feeding chamber facing an entry region (136) of dosage element and an outer chamber (30) facing an exit region (138) of the dosage element. The opening facing a cross section of the exit region of the dosage element is formed in plane transverse to the direction of extension (120) by a closed polygon.
