Abstract
A liquid dispenser comprises a container defining a liquid retaining chamber therein and at least one dispensing port defined through an upper end of the dispenser for providing the sole dispensing outlet for liquid from the chamber. A hydrophobic and microporous anti-bacterial filter is secured over the port to provide a barrier to the ingress of bacteria and particulate matter therethrough and for permitting the egress of sterile liquid therethrough. The dispenser is preferably constructed at its upper end to coalesce the liquid into droplet form upon dispensing thereof.
