ABSTRACT:
A manually actuated dropper device for the mouth of a liquid container that delivers finely metered dosages of liquid is disclosed. The dropper comprises an elastically deformable bellows which can sealingly be fastened onto the mouth of a container along with a threaded cap. The bellows are perforated in a protruding region by a hole serving as a dropper opening. Two spring tongues are also attached to the container; these at least partially surround the bellows and extend substantially parallel to the longitudinal direction of the bellows. The protruding ends of the tongues can be elastically displaced towards each other, thereby squeezing the bellows. Stop surfaces on the spring tongues control the degree to which the bellows are squeezed.
