Abstract:
1. A dry powder inhaler comprising at least one medicament reservoir with an opening and a closure member engaged with the reservoir so as to close the opening, the reservoir having a first surface adjacent the opening and the closure member having an underside including a second surface, the first and second surfaces being in abutment via a deformable seal member interposed between the first surface and the closure member, the underside of the closure member including a pair of slots provided therein and the seal member being provided on the underside of the closure member and extending across substantially all of the underside of the closure member and into the pair of slots, wherein at least one of the first and second surfaces is formed with a projection that increases the contact pressure between the first and second surfaces as the projection engages the seal member, thereby improving a seal formed between the first and second surfaces and reducing the potential for ingress of moisture between the first and second surfaces into the reservoir.
