Abstract: A bottle closure includes a drink spout, a pump mechanism, and a trigger mechanism. The pump mechanism includes a plunger configured to be movable along a first axis to pump a liquid, and the plunger is operatively connected to a first camming surface. The trigger mechanism is connected to the pump mechanism and movable linearly along a second axis. The second axis is transverse with the first axis. The trigger mechanism is configured to actuate the pump mechanism to pump the liquid as the trigger mechanism is moved. The trigger mechanism has a second camming surface configured to engage with the first camming surface of the pump mechanism. The first and second camming surfaces are shaped and configured such that motion of the trigger mechanism causes the second camming surface to engage with the first camming surface to move the plunger along the first axis.
