Liquid and air flow dividing arrangement for baby bottle

Abstract

A liquid and air flow dividing arrangement for baby bottle, comprising a bottle body, a nipple and a cover, and a plurality of check valve being provided on the base of the nipple, wherein said liquid and air flow dividing arrangement includes: a disk body fixed between the base of the nipple and the bottle opening by the fastening of the cover, which has a first sleeve provided on the outer side end to insert within the bottle opening of the bottle body and a second sleeve provided on the inner side end to insert on the inner side of the nipple, a recess being formed between the first sleeve and the second sleeve for receiving the check valve; and a pair of branched pipes extended from the side wall of the second sleeve in the center direction, each branched pipe having an air inlet hole communicated with the recess, both branched pipes being combined at the inside to form an air vent pipe extending towards the bottom of the bottle. The milk liquid during the baby feeding moves from the bottle body along one flow passage M, simultaneously the air enters from the other flow passage A into the bottle for quick supplement so as to balance the internal pressure. The interior of the baby bottle thus maintains a positive pressure all the time, so that the baby can suck milk smoothly without much effort.
