Abstract
The invention relates to a capsule opening arrangement for a powder inhaler device. The arrangement has a first part and a second part which are relatively movable with respect to one another. The first part has a capsule support including an aperture for supporting at least one severable capsule. The second part contains a capsule severing device fixedly located therein so as to pass across the supporting aperture during relative movement of the first and second parts. The opening arrangement provides particular advantages in that the capsule, after severing, has a large open area from which powder can be extracted without any part of the capsule interfering with the powder flow.
