Title: Suction producing disposable pump and dispenser

Abstract: A hollow casing having a vertical bore is inserted into the open neck of a container having liquid therein in such manner as to evacuate all air in the container other than the air in the neck. A piston having a brush at one end is moved into and out of the bore to charge the brush with a selected amount of liquid and to cause a lower portion of the bore to fill with liquid by suction action. A cap secured to the top of the piston and detachably engagable with the neck enables a user to manipulate the piston as desired.
