2092829 9303338 PCTABS00019 There is disclosed a viscous liquid dispenser (1) comprising a reservoir (3) for holding the liquid (at least a part of the reservoir (3) being resiliently squeezable), a measuring channel (2) for measuring therein a quantity of the liquid to be dispensed, a spout (8) in communication with an upper part of the channel (2), and an air trap including an air chamber (6) and a passage (11). A lower end (4) of the channel (2) is in communication with one side of the chamber (6), and the passage (11) communicates an opposite side of the chamber (6) with the reservoir (3). In this way, upon squeezing the reservoir (3), the flow of the liquid through the passage (11) to the lower end (4) of the channel (2) across the chamber (6) from the opposite side to the one side is able in use to release the air bubble from the chamber (6) into the lower end (4) and, upon releasing the reservoir (3), to replenish the chamber (6) with air drawn back through the spout (8), channel (2) and air trap to the reservoir (3).
