ABSTRACT:
A method of reducing spillage when pouring liquid out of a container which includes the following steps. Firstly, place a free floating buoyant member into a resilient deformable container adapted for containing liquid. The liquid must be of greater density than the density of the member such that the member floats upon the surface of the liquid. The container has a fluid flow passage narrower than the dimensions of the member such that the member is prevented from exiting through the fluid flow passage. Secondly, exert a force to temporarily deform the container thereby reducing the volume of the inner cavity and causing the liquid in the container to press the member into a position sealing the fluid flow passage. Thirdly, invert the container thereby placing the container into a pouring position. Fourthly, release the force upon the container such that the container resiliently resumes its original shape thereby increasing the volume of the inner cavity and permitting the member to float away from the fluid flow passage such that liquid freely passes through the fluid flow passage.
