The invention is a device which works similar to a ‘liquor dispenser’. To use the invention the original cap on the beverage carton must be screwed off. The invention screws onto a screw top beverage carton (usually milk/cream carton also referred to as a Gable Top Carton usually made of a cardboard type material). It has a straight pour spout which always keep the spout in pouring position and two chambers. These chambers contain steel balls that function according to angle and pressure when the invention is secured onto the beverage carton threaded neck and is raised to pour liquid into a cup. The steel ball in the main chamber acts as a stopper. This occurs when a specified amount of liquid has rushed through the two side hollow windows of the chamber and out of the spout. When the ball rolls to the top wall of the main chamber it blocks excessive liquid from exiting the spout thus creating a measured serving. This invention is unique because it attaches to the neck of the screw cap housing located atop of a beverage carton by means of an internal thread. The invention is externally located with the chamber reaching inside of the beverage carton just past the beginning of the beverage carton neck.
The invention consists of a ‘main’ chamber which near the top are 2. two side hollowed windows or openings. The main chamber is tube like in form and can be made of plastic or steel, it may or may not have a side venting chamber. The main chamber houses a 3. steel ball which runs up and down. There is a 4. connecting chamber which houses a second 5. steel ball, this is separated from the main chamber. This is located at the bottom of the main chamber. At the top of the main chamber is the 6. straight spout. Surrounding the main chamber is the 7. cap or ‘housing’. The spout protrudes through a hole and seals itself to the cap. 8. Threads are located at the bottom of the cap. The cap and main chamber are fitted together via the spout which is connected to the main chamber which is connected to the connecting chamber. The invention screws onto the beverage/milk carton's threaded neck via its internal threads. Simply turn or screw on and it secures creating a ‘snug’ tight fit preventing leakage.
