1. An inhaler comprising:
- a one piece tubular body, which has a mouthpiece section and is intended to be used only once, and which defines an air flow passage therein, the tubular body having substantially rectilinear sections, at least one intermediate bendable section comprising peripherally extending corrugations; and
a single dose only of an active, inhalable, particulate substance being arranged within the air flow passage, said dose being sealed or closed in relation to an ambient atmosphere by closure means which are to be removed or opened by a user prior to use, and a cross-sectional area of the flow passage defined in the tubular body being unobstructed and not exceeding 75 mm2.

Abstract
An inhaler comprises a tubular body in which an air flow passage is defined. A single dose of an active, inhalable, particulate substance is arranged within the air flow passage and is sealed or closed in relation to the ambient atmosphere by closure means, such as removable caps, a section of the flow passage extending from a free mouthpiece end of the tubular body along a major part of the total length of the flow passage is preferable 7-35 mm2, for example about 20 mm2. The inhaler may be adapted to be used only once, and the tubular body of the inhaler may be a length of a simple tube similar to a drinking straw.

23. An inhaler comprising:
-
a one piece tubular body, which has a mouthpiece section and is intended to be used only once, and which defines an air flow passage therein, the tubular body having a pair of substantially rectilinear sections and an intermediate curved section defining an obtuse angle between the rectilinear sections; and a single dose only of an active, inhalable, particulate substance being arranged within the air flow passage, said dose being sealed or closed in relation to a ambient atmosphere by closure means which are to be removed or opened by a user prior to use and a cross-sectional area of the flow passage defined in the tubular body being unobstructed and not exceeding 75 mm2. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
