The inhaler 40 is assembled as follows. Cover 10 is placed over mouthpiece 12 in order that cover hinge member 18 is brought into close proximity with beveled shaft 22 (Fig. 2). Beveled shaft 22 is then inserted into cover hinge recess 20 to connect the cover to the mouthpiece (Fig. 3). Container 14 is then placed undemeath the connected cover and mouthpiece with the container hinge member 24 in close proximity to the beveled shaft 22 (Figs. 4 and 5). The beveled shaft 22 is then inserted into container hinge recess 26 and the fastening member 30 is snapped into both cover fastening recess 16 and mouthpiece fastening recess 32 to form the dry powder inhaler 40 (Figs. 6 and 7). It is possible to disassemble the inhaler 40 by performing the steps in Figs. 2 to 7 in the reverse order. Disassembling the inhaler may be desirable for cleaning, refilling, or disposal purposes. 10 15 20 25 30 538 845 When the inhaler 40 is not in use for example, during storage or transport, it remains in the closed position illustrated in Fig. 8. In the closed position the cover 10, mouthpiece 12, and container 14 are securely fastened together at one end of the inhaler by the engagement of the fastening member 30 with the cover fastening recess 16 and mouthpiece fastening recess 32. This prevents the cover and the mouthpiece from slipping out of the hinge formed by cover hinge members 18, container hinge member 24, and beveled shaft 22 at the opposing end of the inhaler.The inhaler 40 is assembled as follows. Cover 10 is placed over mouthpiece 12 in order that cover hinge member 18 is brought into close proximity with beveled shaft 22 (Fig. 2). Beveled shaft 22 is then inserted into cover hinge recess 20 to connect the cover to the mouthpiece (Fig. 3). Container 14 is then placed undemeath the connected cover and mouthpiece with the container hinge member 24 in close proximity to the beveled shaft 22 (Figs. 4 and 5). The beveled shaft 22 is then inserted into container hinge recess 26 and the fastening member 30 is snapped into both cover fastening recess 16 and mouthpiece fastening recess 32 to form the dry powder inhaler 40 (Figs. 6 and 7). It is possible to disassemble the inhaler 40 by performing the steps in Figs. 2 to 7 in the reverse order. Disassembling the inhaler may be desirable for cleaning, refilling, or disposal purposes. 10 15 20 25 30 538 845 When the inhaler 40 is not in use for example, during storage or transport, it remains in the closed position illustrated in Fig. 8. In the closed position the cover 10, mouthpiece 12, and container 14 are securely fastened together at one end of the inhaler by the engagement of the fastening member 30 with the cover fastening recess 16 and mouthpiece fastening recess 32.
