Substance containment apparatus

摘要

A storage container for storing powdered baby formula consisting of a first opening mated with a baby bottle and a hollow member rotatably disposed in the container. A wall of the hollow member provides a waterproof seal between the interior of the hollow member and the baby bottle when the hollow member is rotated into a first position. The hollow member defines a second opening which aligns with the first opening when the hollow member is rotated into a second position. The container also has a second open end for mating to a nipple. The container is used to store a pre-measured amount of powdered formula and the baby bottle is used to store a pre-measured amount of water. When in the first position the wall of the hollow member prevents contact between the powdered formula and the water. At a desired time, the hollow member is rotated to the second position to allow the water and powdered formula to mix, thereby producing liquid baby formula. Once thoroughly mixed, the liquid formula is consumed through the nipple.
