an inner housing with a pressurised reservoir of an inhalable composition, the inner housing having an opening;
a breath operated valve operable by a user inhaling on an inhaling end of the inhaler;
a composition flow path from the breath operated valve to the inhaling end via which the composition is dispensed when the breath operated valve is opened;
the breath operated valve being biased closed at one end of the breath operated valve by a biasing member, a first end of the biasing member contacting the breath operated valve;
a bung extending through the opening in the inner housing, the bung being positioned in an opening in the inner housing to support a second end of the biasing member opposite to the first end of the biasing member that contacts the breath operated valve such that the biasing member extends between the breath operated valve at the first end of the biasing member and the bung at the second end of the biasing member;
and a rigid outer housing surrounding the inner housing and supporting the bung.
