  • Publication number: 20040177481
    Abstract: A nursing bottle nipple is comprised of a longer clipping rod and a shorter clipping rod; a round chuck and a C-shape chuck being respectively provided at the tips of both clipping rods with one on the top of the other; both bores of the round and the C-shape chucks being maintained on the same axial when the clip is not used to allow the nipple to be inserted into the internal space defined by both chucks; and the spacing between both bores of the chucks being shortened due to displacement of both clipping rods when external force is applied to both clipping rods to secure holding the nipple without direct contact of one's hand.
