ABSTRACT:
A container having an opening in its top by which it may be filled with liquid and an opening in its bottom through which liquid may be expelled. The bottom opening is covered by the distal end part of a first rod which is surrounded by a gasket; the first rod is connected to a first piston within a first cylinder. The first cylinder forms a second rod which is connected to a second piston within a second cylinder. The rods and pistons are so arranged that a downward force on the second rod causes the first rod to rise allowing liquid to be dispensed from the bottom opening.
