Abstract
A bottle includes an outer vessel formed of a transparent or clear material and an inner vessel slightly smaller than the outer vessel and received therein to create a space therebetween. A cap is secured to the outer vessel and defines apertures therein. The outer vessel defines a closed upper end having apertures aligned with the cap apertures. A valve body providing check valves operable in opposite directions is coupled to a pair of straws which in turn are directed upwardly through the respective apertures and are joined at a common pump bulb. The pump bulb is formed of a resilient elastic material and cooperates with the check valves to displace liquid from the outer vessel to the inner vessel as the bulb is repeatedly squeezed and released. A doll cooperating with the bottle receives the pump bulb in a mouth opening and provides mouth motion to squeeze and release the pump bulb.
