An inhaler for administering powder by inhalation and a method of constructing the same, the inhaler including a member that defines a chamber for containing desiccant, the member including first and second parts which when fitted together define the chamber for containing desiccant. The first part has an outer surface provided with at least one of an internal or external spline and the second part has an inner surface provided with at least one of the other of an internal or external spline, where the splines (28, 36) are dimensioned and/or spaced so as, on fitting together the first and second parts (14, 16), rotationally to fix the first and second parts and define spaces therebetween. |
