Abstract:
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.
