  • Publication number: 20110049178
    Abstract: A circular pill box comprises a body and also comprises a positioning ring, at least one pill disc, a rotating ring and a sleeve ring, which are stacked together from bottom to top inside the body, wherein the positioning ring, pill discs and rotating ring are engaged to each other. When rotated by a force, the rotating ring drives the positioning ring and pill discs to rotate synchronously. The bottom of the positioning ring has a positioning spring platelet press-fitting to one of positioning grooves formed on the bottom of the body. The positioning spring platelet can only rotate with respect to the positioning grooves stepwise and unidirectionally. Via the stepwise unidirectional rotation mechanism, the pills stored inside the pill discs can be sequentially released from the circular pill box according to the predetermined order.
