A dosage bottle is set onto a liquid medicine dispensing device while being held by an adapter (38). The adapter (38) comprises a lifting base (74) on which the bottle is placed and which is capable of lifting, and a clip body (78) for clamping and holding the mouth part of the bottle placed on the lifting base (74). The lifting base (74) is capable of lifting stepwise so that the selectable height of the upper end of the dosage bottle can become a prescribed reference height.
