摘要:
A dispensing device includes: a first chamber and a second chamber, the first chamber being longitudinally movable in the second chamber; an outlet passage fluidly connected to the second chamber; an intermediate valve positioned between an interior part of the first chamber and an interior part of the second chamber. The valve is configured to allow the liquid product to flow from the interior space of first chamber to the interior space of the second chamber when the first chamber is moved in a first longitudinal direction and to limit flow of the liquid product from the second chamber to the first chamber when the first chamber is moved in an opposite second longitudinal direction. A blocking member is movable in concert with the first chamber and configured to seal the outlet passage when the valve limits flow from the second chamber to the first chamber.
