A nursing bottle having a body, a flexible liner, and a feeding nipple. In one embodiment, the body includes a check valve to allow air into a chamber formed between the body and the flexible liner to equalize the pressure in the chamber and prevent air from leaving the chamber. This prevents the liner from expanding and air from reentering the liner. Other embodiments of the nursing bottle include a pump for introducing pressurized air into the chamber and thereby expelling air from the liner. In still other embodiments, the bottle comprises a two-part body in which the parts of the body are slidably and sealably engageable with each other wherein movement of the parts relative to each other pressurizes the air in the chamber and expels air from the liner. Disclosed are also methods of feeding an infant or animal utilizing such nursing bottles.

[ What is claimed is:] [1.] A nursing bottle comprising;a body, open at an upper end, and a lower end;a flexible liner, open at one end, said liner open end suspended from said upper open end of said body;a feeding nipple attachable to the body upper end;and a cap with an aperture, and a valve in said aperture, attachable to the open lower end of the body, and upper end over said feeding nipple, that when the cap is attached to the lower end of the body, said cap creates a chamber between the liner and the body, that when liquid contained within the liner is removed during feeding, a vacuum is created in said chamber to readily draw air into said chamber through said valve so as to compensate for the volume of liquid removed from said liner, and when feeding stops, said valve prevents air from being drawn through said nipple into said liner.
