An automated station is provided with a tool comprising a linear actuator having a power supply inlet adapted to be releasably connected to a feed line; a container for edible liquids; a closure movable by means of the linear actuator between a closed position in which the edible liquid is in the container so that the liquid is shaken by the action of the automated station and an open position in which the edible liquid is poured out of the container in a controlled manner through the action of the automated station; and a lever arm pivoted and connected between the linear actuator and the closure so as to reduce the load applied by the actuator to decrease a first resultant force applied by the closure on a fluid seal in the closed position with respect to a second force applied by the actuator to the pivoted lever arm.
