Abstract:
A method of introducing each of a plurality of doses of particulate material into a respective compartment of a container, the container comprising a plate having a plurality of apertures, each of which constitutes a respective compartment, the method comprising the steps of:a) inserting a respective protuberance into each compartment so as to reduce the capacity thereof;b) filling each compartment with said particulate material, with the respective protuberance inserted in said compartment by positioning the plate on a porous bed with the apertures in communication with a reservoir of particulate material; applying gaseous pressure to the reservoir so as to transfer particulate material from the reservoir to the apertures, the porosity of the bed being such as to allow the passage of gas but to prevent the particulate material from passing all the way through the apertures and escaping from the underside of the plate; andc) removing said protuberances,wherein the volume of each dose of material is less than that of its respective compartment.
