A bottle 2 of liquid medicine has a self-sealing closure in its neck 14 , the bottle being flexible such that when it is inverted or tilted downwardly, squeezing the bottle produces a flow of liquid medicine through the closure, and releasing the bottle terminates the flow of liquid medicine. The bottle is shaped so as to assist the operation, being of generally box-form, having side walls 6, 8 which support larger front and rear panels 10 , which can be controllably flexed. |
