A multi-reservoir dispensing, disposable and sterile container has at least two separate and distinct reservoirs positioned adjacent to one another, and which can be readily manufactured using blow-fill-seal technology. The reservoirs contain components of a mixed pharmaceutical formulation, which is prepared at the time of dispensing from the container by blending of the contents of the reservoirs. Liquid flow channels extend from each reservoir and merge together at or near an exit aperture of the container, and a mixing feature can be employed at or downstream of the point of merging. In the container as provided to a user the exit aperture is blocked by a seal, which is removed prior to dispensing.
