A versatile feeding system for use by infants and children in which liquid from a bottle is either fed out of the bottle through an adapter, through the improved nipple and into the mouth of the infant or child; or liquid from the bottle is fed out of the bottle through the adapter, through a flexible tube, and into and through a nipple assembly which is adapted to be placed in the mouth of the infant or child. The adapter includes a pair of halves which are held in place in the open top of the bottle by a screw cap, each half including a flow regulator of resilient material having slits therein which open or close due to suction pressure, and at least one flow restrictor having slots therein for controlling the volume rate of flow of liquid through the adapter. The elongation and deformation of the regulator is controlled by two reducers in one half housing and by one reducer in the other half housing, each reducer has a centrally located hole beveled on one side. The nipple assembly includes a nipple coupled to a rigid extension which couples the opposite end of the tube to the nipple. Once the flow of liquid commences to the nipple assembly, the tube is primed and remains until the bottle and tube are drained. The various parts of the adapter and nipple assembly can be disassembled for cleaning and reassembled for use. |
