A positioning device for setting a bottle at a predetermined angular position, which device is provided with a bottle supporting mechanism to support the upper end portion of the bottle and a mechanism which imparts relative rotary motion to the bottle and an engaging member or members being brought into engagement with the positioning spot of the bottle. When the engaging member is turned, the bottle is rotated to a predetermined angular position together with the engaging member after the spot is brought into engagement with the engaging member. In the case where the bottle is turned, the bottle is not rotated after the spot is brought into engagement with the fixed engaging member. The bottle supporting mechanism has the function of holding the bottle stably at a precise position and this function is enhanced by the provision of a bottle receiving opening, that is, a wall surface to restrict movement of the outer bottom bottle surface, around the supporting member which supports the bottom portion of the bottle.
