Abstract
The invention relates to a dispensing device designed for liquids contained in a flexible bag with a dispensing outlet.
The device comprises a first wall and a movable pressure plate that can be pivoted from a first position to a second, closer position toward the wall. When moved, the pressure plate compresses the flexible bag to push out part of the liquid.
A pressure system drives this movement. It includes a pressure element connected on one side to the pressure plate and on the opposite side to a pivotable support inside the device. When the support pivots, it tensions or loads the pressure element, allowing smooth, controlled movement of the plate.
The geometry of the mechanism is designed so that as the plate moves, the force vector applied becomes more tangential to the plate’s motion path, improving efficiency and control in dispensing.
