The present invention relates to a baby bottle, and more particularly, to a baby bottle comprising a container (10) having an injection port (101) at the upper portion; and a nipple (30) coupled to the injection port (101) of the container via a fixing means (20), wherein the baby bottle further comprises: an outer cup (40) which has a sticking protrusion (401) and a first ventilation hole part (402) on the outer circumferential wall and is installed at the injection port (101); and an inner cup (50) which is slidable vertically inside the outer cup (40), has a second ventilation hole part (502) communicated with the first ventilation hole part (402), and is insertingly installed into the outer cup (40), thereby, as a baby sucks the baby bottle and leaves the contents in the mouth, preventing contents in the mouth, such as saliva or vomitus, from re-entering into the baby bottle to stop the contents in the mouth mixing with the contents in the baby bottle and thus inhibit degradation of the contents in the mouth and ensure reingestion of the contents remaining in the baby bottle. |
