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.

Abstract: A bottle closure includes a drink spout, pump mechanism, trigger mechanism and lock mechanism. The trigger mechanism is moveable between a first trigger position and a second trigger position. The lock mechanism is engageable with the trigger mechanism and movable between an engaged position and a disengaged position. The lock mechanism is adapted to engage the trigger mechanism when the lock mechanism is in the engaged position and thereby prevent the trigger mechanism from moving from the first trigger position to the second trigger position. The lock mechanism is further adapted to permit the trigger mechanism to move from the first trigger position to the second trigger position when the lock mechanism is in the disengaged position.
