Patent ID: 8573449

Claim:
A dispensing device for dispensing a liquid, comprising: a pump, with an elastically deformable or flexible, dome-like section which borders a pump chamber for the liquid or fluidically connected with the liquid, wherein the liquid can be pumped or conveyed by a reversible deformation of the section, and the liquid can be subsequently taken up via a sucking action, into the pump chamber by automatic returning of the section to an initial position, and an actuating element associated with a housing part acting on the section for the reversible deformation of the section from the initial position into a deformed state, wherein the section has a concave area in one or more of the initial position and in an unloaded state which can be pressed or deformed in order to pump the liquid into the pump chamber, wherein a thickness of the concave area of the dome-like section has a lesser wall thickness than a wall thickness of the dome-like section.
