Dual chambered mixing and dispensing vial

A dosage device for the delivery of a measured quantity of a liquid or flowable paste, such as a medicament, comprises a cup component and a compartmented component which is secured within the cup component and rotatable with respect thereto about an axis, the cup component having a radial base wall with an opening radially offset from the axis, the compartmented component having axially extending walls bounding a plurality of compartments each of which has an open end and each of which can be brought, by relative rotation of the two components, into alignment with the base wall opening, each compartment having in its outer wall an outlet which is at a respective different axial spacing from its open end, the cup component and that outer wall bounding a dispensing space to receive liquid or flowable paste from the compartment.
