Abstract
A device having a body (10), a reservoir (100) axially slidable relative to the body (10), a metering valve (200), a blocking element (500), a triggering element (600), a triggering system controlled by inhalation (60), an actuating member (800) cooperating with the blocking element (500), a cover (11) with a central axial sleeve (110) with a lower axial edge (111), a push member (810) mounted in the cover around the central axial sleeve (110), and a spring (850) disposed around the central axial sleeve (110) between a bottom of the cover and the push member. The lower axial edge (111) of the central axial sleeve is deformed after assembly of the push member and the spring in order to produce a retention collar of the push member and form a pre-assembled subassembly that is fixed to the body.
