摘要

The invention relates to a nursing bottle of the type comprising an outer open body (1) which houses a flexible casing (2) that is intended to contain the fluid food product, a flexible nipple (4) which is used to dispense the product, a check valve (3) which is disposed between the opening (20) in the casing (2) and the nipple (4) and, close to the end (40) of the nipple (4) which is pierced with at least one slit (41), a second check valve which can open and close depending on whether or not suction and/or pressure respectively is/are being applied. The aforementioned nipple (4) is provided with means (45) that enable the slit (41) to switch from a closed position in an impervious manner to an open position such that the food product can pass therethrough when a pre-determined pressure is exerted by the mandible. In this way, the slit (41) which is associated with the aforementioned means (45) forms the second check valve.
