Abstract: A universal adapter for retaining a baby nipple/pacifier or other removable liquid dispenser on a bottle includes a substantially rigid closure having a downwardly extending rim, for engaging the mouth of a bottle from the outside, and a central upwardly extending fitting, with a central through aperture. The fitting is designed so that a liquid dispenser having a resilient mouth can be pushed onto the fitting. Contained within the closure is a resilient insert which includes an annular portion that acts as a gasket when the adapter is installed on the bottle. The resilient insert may have a central downwardly extending plug, formed integrally with the annular portion, which can be inserted into a narrow-mouthed bottle such as a water bottle.

Abstract: A convertible bottle for children has a lid which can be manipulated to provide alternative liquid outlets, for example, a nipple, a foldable sippy spout, and a pop-up sports-type valved outlet. The cap, or a portion of the cap, may be inverted to expose different outlets, and each of the outlets forms or contains a valve for controlling liquid flow to prevent spillage.

Abstract: A container of sterilized fluoridated water, powdered infant formula, and a ready-to-use sterile feeding nipple are hermetically sealed within an enveloping structure. Once the structure is opened, the water and formula are removed, the formula is dissolved in the water in the bottle, and the nipple is then applied to the bottle. The used components may be placed back in the container for reuse or disposal by reapplying an outer lid. In a preferred embodiment, the enveloping structure is a cylindrical can and the water container is a bottle which is centered within the can by indentations in the wall of the can.

Abstract: A bottle of water and powdered infant formula or ready-to-use, pre-mixed, liquid infant formula, juice or other liquid and a ready-to-use sterile feeding nipple device are hermetically sealed within an outer container. Once the outer container is opened, the bottle is removed and the nipple device is then applied to the bottle. The used components may be placed back in the container for reuse or disposal by reapplying an outer lid. In a preferred embodiment, the outer container is a cylindrical can and the bottle is centered within the can by indentations in the wall of the can.
