Abstract
An adapter for the mouth of a container, such as a bottle of liquid medication, includes a body member adapted to fit sealingly into the mouth of the container, body member having a central aperture for receiving the nozzle of a syringe-type medication dispenser. In one embodiment of the invention, the body member includes a vent hole and a downwardly depending tube adapted to extend into the container to enable liquids to be drawn from deep containers without inverting them. A valve device retains the liquid in the tube near the body member. The valve is in the form of a flexible web extending transversely across the central aperture, the web having a slit or opening therein for receiving the nozzle of the dispenser to enable it to extend axially therethrough to gain access to the liquid medication disposed within the container.
