Abstract: A feeding bottle comprises a bottle body of a wide neck with an opening, a substantially rigid upwardly dome-shaped adapter ring detachably fitting to the neck and having an upper supporting surface defining a central opening, a teat with its flat radial flange merely resting on the supporting surface, and a clamping cap to retain the teat by clamping the teat flange against the supporting surface of the adapter ring. The supporting surface serves as a counterclamping surface for the clamping attachment of the teat. The outer diameter of the teat flange is substantially smaller than the inner diameter of the opening of the wide bottle neck.
