Abstract
A drop dispenser for accurate dispensing of drops of a predetermined size. The dispenser comprises a container joined to a tip by a neck. The liquid from the container is forced into a flat flow passage in the neck and discharged into a chamber in the tip where the liquid coalesces. The liquid is then dispensed through an aperture which controls the size of the drop dispensed. The size of the aperture is independent of the pressure applied to the bottle. The flat flow passage prevents the flow of liquid therethrough at such a rate such that the liquid could be dispensed as a stream and not at the desired drop size.
