The invention relates to a nursing bottle comprising a rigid body (1), a nipple (9), which is joined to the rigid body (1) by means of a nipple collar (7), and a means to compensate for the vacuum created in the rigid body (1) when the liquid (3) contained in said body (1) flows through the nipple (9). According to the invention, said compensating means comprises a plunger (15, 17) that can move in relation to a communication chamber (12, 13) disposed in the bottom of the rigid body so that said plunger can be moved against an elastic return element (19), which is located between the plunger (15, 17) and the communication chamber (12, 13), from a closed position, wherein the communication chamber is sealed, to an open position which creates an air flow through the communication chamber.
