Dispensing head and dispensing device for the metered dispensing of liquid preparations, and possible uses

A dispensing head for a dispensing device for metered dispensing of a liquid preparation comprising:

• a passage channel that has an inlet opening arranged at an inner side and an outer dispensing opening for the liquid preparation, wherein the inlet opening connects an inner space to an outer environment via the passage channel;
• and
• a valve comprising a valve body that is arranged on the side of the inner space above the inlet opening and the inlet opening is configured as reversibly sealingly closable for the liquid preparation with respect to an inner space;
• wherein the valve body comprises at least two sealing lips which are one inner sealing lip and one outer sealing lip and wherein the at least two sealing lips are arranged concentrically at the valve body;
• wherein the at least two sealing lips are formed on a side of the valve body facing the inlet opening and seal the inner space with respect to the inlet opening when the valve body closes the inlet opening;
• wherein the valve comprises a frame that has at least one fastening element to which the valve body is fixed, with the frame being fastened to the dispensing head;
• and
• wherein the valve body, the frame, and the at least one fastening element are formed in one piece, such that when the pressure on the valve body is increased the valve body closes the inlet opening of the passage channel.
