Abstract: This patent discloses tools, methods and systems for dispensing soap. The tools, methods and systems include a draw-back chamber constructed around and in line with the fluid path between a spout assembly for delivering soap to a user and a pump mechanism for supplying the soap. The draw-back chamber contains port openings into the fluid path. When the pump mechanism is actuated to dispense soap, the draw back chamber is collapsed and soap within it is dispensed with the main dose of soap supplied by the pump mechanism. When the pump mechanism is allowed to return to its extended rest state, the draw-back chamber expands, drawing soap into it through the port opening to prevent soap from hanging and dripping at the end of the dispensing tube.
