ABSTRACT OF THE DISCLOSURE The present invention relates to a feeding bottle having an air intake valve, said feeding bottle having a bottom cap comprising an inverted cup shaped portion, which extends into the bottle and is surrounded by a stretched, resilient rubber sleeve covering a radial hole in the cylin- drical wall of the cup portion to form an automatic air intake valve. The radial hole is provided in a part- cylindrical facet of reduced cross sectional curvature, whereby even a large rubber sleeve is easily liftable from the hole for sensitively admitting air into the bottle whenever a moderate suction vacuum is built up therein.
