Abstract
An inhaler for administering powder by inhalation and a method of constructing the same. The inhaler includes an inhaler body having an opening therein and an indicating wheel disposed in the inhaler body for providing an indication as to the usage of the inhaler. The indicating wheel is disposed such that at least part thereof is visible through the opening and so as to be rotatable in a diametrical plane containing a central axis of the inhaler body. The inhaler also includes a divider substantially closing one end of the inhaler body and a storage unit disposed in the inhaler body. The storage unit includes a storage chamber for storing powder for inhalation. The inhaler body and the divider are formed as a single integral unit of an opaque material and the storage unit is formed of a transparent material and has a portion which substantially fills the opening.
