ABSTRACT:
The present invention relates to a feeding-bottle device with an adjustable air inflow, comprising a feeding bottle, a teat and a ring clamping the teat onto the feeding bottle. The teat has an annular collar intended to be retained between the rim of the feeding bottle and a flange of a clamping ring screwed onto the feeding bottle. The collar bears on the rim by means of ribs betwen them delimiting air-inlet passages. Opposite a localized annular zone of the rim, each rib has an interruption arranged in correspondence with a moulding for the bearing of the flange on the collar. Thus, by screwing the clamping ring into the feeding bottle to a greater or lesser extent, the effective cross-section of the air-inlet passages can be adjusted, deforming the collar as a result of a lever effect exerted between the moulding and the ribs, especially until the air inlet passages are closed. Leaks of the liquid contained in the feeding bottle when the child stops sucking can thus be prevented.
