Abstract
A container for dispensing a predetermined amount of liquid through a dispensing tube is disclosed. A valve is dimensioned to contain and dispense a predetermined about of liquid and dispense the liquid through a dispensing tube in contact with the valve. The liquid is in fluid contact with the inlet port when the base is in a first position and out of fluid contact with the inlet port when the base is in a second position. Thus, the valve fills with liquid when the container is in a substantially horizontal position while angling the container removes the liquid from contact with the valve and stops the fluid flow. Preferably the container has a sealable, watertight lid that receives the dispensing tube and incorporates vent holes to enable airflow into the container. The fluid inlet port can be placed in the side or top of the valve. The valve can alternatively be a tube with fluid and tube inlets in fluid communication. An air vent can be incorporated within the dispensing tube to prevent using the dispensing tube as a straw, it is preferable to include a drinking shield.
