Abstract

A 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 unusable without mixing the two ingredients until the time of use. Using this device, the user can pre-measure ingredients and assemble the containers 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.

Claims

1. A baby bottle for the rapid mixing of a prestored substance with a fluid comprising:

primary and secondary containers in fluid communication, said containers having walls and mating orifices, with said primary container adapted to contain said prestored substance and with said secondary container adapted to contain said fluid;

means including an apertured nipple of flexible material at the top of said primary container and connecting with the interior of said primary container for dispensing said fluid after mixing, said nipple having a longitudinal extent so as to form a chamber having a vertically extending portion;

a stemmed disk having a stem with a distal end opposite the end with said disk, said disk adapted to seal the orifice associated with said primary container, said distal end of said stem being positioned proximate the tip of said nipple, with the stem of said stemmed disk projecting into said primary container along the longitudinal centerline thereof into the vertically extending portion of said nipple, the portion of said stem positioned within said vertically extending portion of said apertured nipple being spaced from said nipple to define a free annular portion therebetween, said disk having an outer periphery disposed in the orifice associated with said primary container, said containers being demountable to permit refilling and reuse as well as permitting reuse of said stemmed disk; and

, means for sealing said disk in said orifice in a snap fit including an annular member at the orifice associated with said primary container, said annular member projecting inwardly from an interior wall of said primary container, whereby said disk is retained in sealed communication with said annular member in a snap fit, and whereby movement of said stem causes said disk to move with respect to said annular member, thus to become unsnapped to permit said mixing.

2. The system of claim 1 wherein each of said containers include matching screw threads adjacent the orifice thereof for the attachment of the containers together.
