Rotary Dosing Device

Abstract

A rotary dosing device includes a rotating bucket, a container body, a cap top having an opening, a first restraining element, and a second restraining element. The rotating bucket has at least two partitioned dosing slots. The container body is rotatably coupled with the rotating bucket. The cap top is capped on the container body. The first restraining element is connected to both the container body and the rotating bucket for applying and removing restriction to movement between the container body and the rotating bucket in a packaging state and a using state respectively. By means of providing the first restraining element and the second restraining element, when the dosing device is not in use, the rotating bucket is prevented from rotating with respect to the container body and the opening is prevented from opening, so that the dosing device is convenient for packaging and transporting.
