Abstract
Abstract The leakage preventing baby bottle of the invention incorporates a collar inserted over the neck of the bottle, supported by the body of the bottle and held in place by the screw-on nipple cap employed. For a cylindrically shaped bottle, the collar is selected of a greater diameter dimension than that of the bottle itself so as to prop the bottle at an upwardly directed angle to prevent the nipple from leaking or dripping even at such times as the infant, or toddler, is not sucking, and with the bottle at rest. In a preferred embodiment of the invention, the collar is comprised of a pair of see-through apertured disks, sandwiched together, and with the lower one being provided with a luminous coloration along its circumference to enhance easy-finding in a darkened environment.
