We claim: 1. Apparatus for loading a defined quantity of a powdered medicament formulation into a container for use in an inhalation device, comprising: a perforated plate which has a first side on which powdered medicament formulation is, in use, disposed, a second side and a perforation having a first opening in the first side and a second opening in the second side, a closing member located at the second side of the perforated plate for closing the perforation at the second opening to enable filling of the perforation with a defined quantity of powdered medicament formulation through the first opening, at least one leveler non-contactingly spaced from the first side of the perforated plate for directing powdered medicament formulation located on the first side into the perforation through the first opening, the at least one leveler having a leveling face oriented at an acute angle to the first side of the perforated plate, a wiper located at the first side of the perforated plate for wiping away powdered medicament formulation overlying the first opening of the perforation, and a compacting pin insertable into the perforation through the first opening to compact and eject powdered medicament formulation in the perforation; wherein the apparatus is configured and arranged to provide for relative movement of the perforated plate, the closing member, the at least one leveler, the wiper and the compacting pin to successively effect: i) a filling mode, in which the closing member closes the second opening of the perforation and relative movement is provided between the at least one leveler and the wiper, on the one hand, and the perforated plate, on the other hand, which results in successive movement of the at least one leveler and the wiper over the first opening of the perforation to fill the closed perforation with a defined quantity of a powdered medicament formulation which is located on the first side of the perforated plate on the relative path of movement of the at least one leveler and the wiper, ii) a compacting mode, in which the compacting pin is inserted through the first opening of the perforation so as to compact the defined quantity of powdered medicament formulation in the closed perforation from the filling mode, and iii) a loading mode, in which the closing member opens the second opening and the compacting pin ejects the compacted powdered medicament formulation from the compacting mode through the second opening for loading a container for an inhalation device in registration with the second opening. 2. Apparatus according to claim 1, wherein the closing member is a blanking plate. 3. Apparatus according to claim 1, wherein the closing member is a blanking pin insertable into the perforation through the second opening. 4. Apparatus according to claim 3, wherein the blanking pin is movable within the perforation to adjust the volume of the closed-off perforation. 5. Apparatus according to claim 1, wherein the acute angle is between 1 and 60°. 6. Apparatus according to claim 1, wherein the acute angle is between 5° and 25°. 7. Apparatus according to 1, wherein the leveling face presents multiple acute angles to the first side of the perforated plate. 8. Apparatus according to claim 7, wherein the leveling face is curved in form. 9. Apparatus according to claim 7, wherein the leveling face is articulated. 10. Apparatus according to claim 1, wherein the leveling face has a flat tail section. 11. Apparatus according to claim 1, wherein there are plural levelers arranged to move in succession along the path. 12. Apparatus according to claim 11 wherein the levelers are arranged to provide a leading leveler and at least one trailing leveler and wherein the leading leveler is spaced from the first side of the perforated plate by a distance which is not less than that of the least one trailing leveler. 13. Apparatus according to claim 1, wherein the perforated plate has plural said perforations and each perforation is associated with a compacting pin. 14. Apparatus according to claim 3, wherein the perforated plate has plural said perforations and each perforation is associated with a blanking pin. 15. Apparatus according to claim 1, wherein the perforated plate is static and the at least one leveler and the wiper are movable.
