Abstract
A bottle liner or insert for administering at least two different liquids to a feeding child, includes a first reservoir of polymer fabric, the reservoir comprising two walls sealed together at their mutual bottom and sides and having an open top and flaps extending from both walls at the top of said first reservoir; a sheet of polymer fabric having a smaller area than either wall of said first reservoir, the sheet sealingly anchored to the inside of either wall such that the sheet and inner wall together form a second reservoir extending to and open at its top, the sheet also having a flap extending from its wall at the top; and a valve in fluid communication with and disposed between the first and second reservoirs.

A bottle liner for administering at least two different liquids to a feeding child, comprising:
- (a) a first reservoir, said reservoir comprising two sheets sealed together at their mutual bottom and sides, and having an open top and flaps extending from both walls at the top of said first reservoir;
- (b) a second reservoir, said second reservoir comprising two sheets sealed together at their mutual bottom and sides, and having an open top and flaps extending from both walls at the top of said second reservoir, said first reservoir and said second reservoir sharing a common sealing wall;
- and
- (c) a passageway in said common sealing wall in fluid communication with and disposed between said first and said second reservoirs whereby, when said liner is installed in a bottle, the passageway opens at the urging of a vacuum created by the child, thereby allowing flow from the first reservoir to the second reservoir.
