Abstract: A method of reducing spillage and residual liquid when pouring liquid includes temporarily deforming a liquid-carrying resilient container to press a buoyant member into a position sealing a fluid flow passage of the container, which is then inverted and the force is released to permit the member to float away from the passage such that liquid freely passes therethrough. When the fluid level is no longer sufficient to float the member away from the passage, an additional step prevents the ball from becoming or remaining seated in the sealing position so that residual liquid left in the container can be drained through the passage. Novel containers feature a ball-shaped member of larger size relative to the passage to ease unseating of the member therefrom for draining of residual liquid, and novel two-piece container constructions accommodate insertion of such larger balls prior to final assembly of the container.
