Abstract:
A liquid dispensing assembly comprisinga flexible container defining an inner space therein adapted to store liquid; a dosing device connected to the container and adapted for dispensing liquid from the container, the dosing device comprising a base bottom connected to the container; a filling chamber comprising a filling chamber bottom and a vertical sidewall connected to the filling chamber bottom; at least one feed line system adapted to fluidly connect the inner space of the container the filling chamber, the feed line system comprising an inflow opening defined in the inner space of the container; and at least two pieces of line mounted on the filling chamber bottom, each piece of line defining an outflow opening located into the filling chamber, each of the at least two pieces of line being adapted to individually and exclusively fluidly communicate with the inflow opening such that each outflow opening is adapted to individually and exclusively fluidly communicate with the inflow opening; wherein the filling chamber bottom is movably mounted on and substantially in contact with the base bottom so that the filling chamber is movable relative to the base bottom, such that the inflow opening may be individually and exclusively brought into fluid communication with a selected outflow opening selected from the outflow openings defined by the at least two pieces of line by a movement of the filling chamber relative to the base bottom; a squeezing of the flexible container causes liquid to flow from the inner space of the container through the inflow opening, through the selected outflow opening, and into the filling chamber; a first outflow opening of the at least two outflow openings is located at a first height relative to the filling chamber bottom and a second outflow opening of the at least two outflow openings is located at a second height relative to the filling chamber bottom, the first and second heights differing from each other; and when the squeezing of the flexible container is sufficient to fill the filling chamber with liquid to a height greater than a height of the selected outflow opening, liquid drains out of the filling chamber through the outflow opening, through the inflow opening and into the flexible container until the filling chamber is filled to the height of the selected outflow opening.
