Abstract: A formula bottle includes two separate sealed chambers, a liquid chamber and a formula chamber. A first seal seals the two chambers from one another and a second seal seals the formula chamber from the nipple on the formula bottle. Rotation of the liquid chamber counterclockwise opens the seal between it and the formula chamber, allowing the formula powder and the liquid to mix. Shaking of the bottle causes the two components to mix completely. In order for the mixed formula to be dispensed to a feeding infant, a bottle collar, which secures the nipple to the formula bottle, is rotated counterclockwise to open the second seal to allow an infant to feed.
