A method of producing a container (201, 231 350) having a plurality of apert ures (e.g. 202, 232, 352) each containing a respective dose of powdered material, such as a medicament, involves placing an empty c ontainer in a position in which its apertures communicat e with a reservoir (216, 84) of powdered material. The material is then passed , for example by the flow of gas, from the reservoir int o the apertures to fill the latter, and the container is then separated from the r eservoir and the apertures are optionally sealed with sh eet material (204, 206, 321, 323). Since the apertures are filled, their volume determine s the amount of each dose which therefore does not have to be measured prior to introduction into the apertures. The container may compris e a rigid or flexible plate and in latter case can be su bsequently rolled into the form of a cylinder for use in an inhaler. Apparatus for perf orming the method, and an inhaler for use with a cylindr ical container, are also shown. |
