ABSTRACT OF THE DISCLOSURE To the body of a feeding bottle, of the type in glass or other reusable material, or of the type in plastic or other disposable material, there is applied a valve for manual regulation, without interruption of feed- ing, of the quantity of air which must replace the escaped liquid as a function of the sub-pressure generated by the sucking. The nipple has an area which is of lesser thickness than the rest and is therefore of a geometry that varies automatically with the sub-pressure present in the bottle so as to appraise the variation of this sub-pressure in the course of the sucking and to control the effects of said air valve.
