AbstractA fluid mixing system is provided to permit rapid mixing of a prestored powdered substance such as powdered milk with a liquid in which, in one embodiment, baby bottles are stacked one atop the other in fluid communication, with an internally carried stemmed disk preventing powdered contents of the upper bottle from entering the liquid carried by the lower bottle until the stemmed disk is dislodged from the aperture between the bottles, the stemmed disk falling into the lower bottle such that the mixing can occur without opening or separating the two bottles. The invention thus allows the separate storage of two pre-measured fluent materials within the same container, and to facilitate the mixing and dispensing of those materials at a later time without opening the container. The benefits of this are that the user can prepare in advance mixtures of materials which, if stored in a combined state, will sour, harden, or otherwise become usable without mixing the two ingredients until the time of use. Using this device, the user can pre-measure ingredients and assemble the container at a convenient time. The resulting assemblies can be stored and transported easily. When needed, the user can mix the prepared contents in a few seconds with only one hand, with the contents being prevented from spilling during storage, transportation, mixing, and use.
