ABSTRACT OF THE DISCLOSURE An adapter for connecting in fluid communication a liquid dispensing syringe with the interior of a bottle containing a liquid, such as a liquid medication, includes a tubular body member composed of resilient material and being generally cylindrical in shape to fit snugly within the mouth of the bottle. Projections or beads are provided on the body member for engaging the inside surface of the bottle thereof in a continuous line of engagement therewith with a high pressure per unit area of engagement. An opening extends axially through the body member for receiving the nozzle of the syringe, and the opening includes a forward nozzle receiving portion and a rear portion. The axial length of the forward portion is substantially the same as the axial length of the nozzle so that the exit end of the nozzle terminates at the rear enlarged portion when the nozzle is inserted fully within the opening. A fluid pathway disposed at the rear portion of the opening for the adapter guides liquid to the forward nozzle receiving portion and prevents or minimizes the introduction of air into the attachment opening. In one form of the invention, the fluid pathway is in the form of an enlarged portion of the opening to prevent air from entering the syringe when the bottle is inverted to fill the syringe.
