Abstract
The present invention regards a method for filling containers with a single-dose composition comprising or, alternatively, consisting of mannitol in powder form. Such process comprises the following steps: a) breaking up a coherent mass of powder mannitol, so as to obtain a broken-up mass from said coherent mass; c) filling a plurality of containers with the broken-up mass of step a), wherein a bulk density of the coherent mass is smaller than a bulk density of the broken-up mass.
Claims16
A method for filling containers with a composition that comprises or, alternatively, consists of mannitol in powder form, comprising:
- a) breaking up a coherent mass of mannitol powder using a centrifugal drum sieve having a mesh gap size in the range of 2.0-5.0 millimeters, so as to obtain a broken-up mass from said coherent mass;
- and
- b) filling a plurality of containers with the broken-up mass of step a)
- wherein each container comprises a container compartment that comprises a first volume fraction and a second volume fraction, wherein at the end of step b) the first volume fraction is occupied by a single-dose composition and the second volume fraction is free from said composition, and wherein the first volume fraction is about two-thirds of a total internal volume of the container compartment and the second volume fraction is about one-third of the total internal volume.
