ABSTRACT:
A nursing bottle includes a pair of reservoirs which are selectively coupleable to a single nipple. The bottle includes a hollow body, an intermediate ring having a valve disk with two apertures and a nipple carrier having a valve plate with a single aperture. The nipple carrier is mounted over the intermediate ring and rotates to selectively connect the valve plate aperture with either of the valve disk apertures. A separate sack or flexible bag type liquid reservor is connected to each of the valve disk apertures. A conventional bag reservoir may optionally be fitted in the hollow body with the nipple carrier then being engaged directly over the body. In an alternate embodiment, the body may comprise a rigid walled bottle with a longitudinal partition forming two reservoirs. The nipple carrier and valve plate are engaged over the rigid walled bottle and are rotated to register the valve plate aperture with either reservoir. A method of reducing the risk of tooth decay while using the bottle for pacification purposes includes filling one of the reservoirs with a sugar containing liquid and the other reservoir with a sugar free liqid. The nipple is interconnected to the sugar containing liquid and the child is permitted to relax while drinking the sugar containing liquid. Thereafter, the nipple is connected to the sugar free liquid prior to cessation of sucking to rinse the sugars from the child's oral cavity.
