An combined nursing bottle nipple and pacifier device includes a fitting designed to be mounted on a push-pull valved dispenser spout of a conventional beverage container. The fitting also contains an independently operable valve of its own, so that the fluid path may be closed when desired. The fitting's valve is preferably a rotary valve, which can be operated by turning one part of the fitting with respect to another. When the fitting's valve is closed, the device is useful as a pacifier. The nipple may, alternatively, contain a check valve which can be opened by manipulating the fitting so as to drive a probe, supported in the fitting against the check valve. |
