ABSTRACT:
A vertical blade in the spout of a container, on the inside lip of a container or across the top diameter of a container. The blade forms a triangle in the center of the spout. In a spoutless container, the blade extends from the top lip horizontally inside the container for up to two inches, then diagonally down to the inside of the container. Placed across the diameter of a container, the top of the blade is flush with the top of the container and extends down to a maximum of two inches, making a rectangle across the container. Splattering is prevented because liquid is cut, then pulled toward the center. Cohesion pulls liquid toward the blade. Adhesion brings the liquid together after it passes the blade.
