Abstract: A liquid dosing device for dispensing a metered dose of liquid from a squeezable container, comprising an outlet passage leading to a discharge opening; a dosing chamber positioned behind said discharge opening and having at least one entrance opening allowing a charging flow of liquid from said container into said dosing chamber under the influence of weight of liquid, and a drive opening allowing a control flow of liquid from said container into said dosing chamber in response on a rise of pressure of liquid in the squeezable container; a floating plunger movably arranged in the dosing chamber so as to advance upon said rise of pressure from a rest position in which under the influence of a lifting force of buoyancy said floating plunger closes said drive opening, into a blocking position in which said floating plunger blocks said outlet passage, wherein said floating plunger when advancing into said blocking position, pushes said liquid charged into said dosing chamber, to said outlet passage; a stop seat
