An insert that has a one-way valve that allows for one-way flow of liquid in response to reduced pressure. The insert is configured to be installed in a baby bottle to form two chambers—a reservoir chamber and a dispensing chamber. The insert also is provided with a valve failure mechanism which allows a user to force the one-way valve open in the absence of reduced pressure, which allows a user to prime the dispensing chamber (the nipple) prior to beginning feeding.

Feeding bottle with one-way liquid flow to prevent contamination

A dual chamber nursing bottle includes a first, relatively larger, storage chamber and a second, relatively smaller feeding chamber. A soft rubber nursing nipple is connected to the second chamber for feeding an infant. The first and second chambers are connected by a threaded closure. A transfer valve is mounted on the threaded closure to allow the transfer of selected quantities of milk from the first chamber into the second chamber.

Dual chamber nursing bottle

A dual chamber nursing bottle includes a first chamber, a second chamber, a closure which defines the second chamber, and a valve member which communicates between the first and second chambers to control the flow of fluid from the first chamber to the second chamber and then feed an infant using the nursing nipple which is mounted on the first chamber.
