Abstract
An inhaler with an inner housing with a pressurised reservoir of an inhalable composition. A breath operated valve is operable by a user inhaling on an inhaling end of the inhaler. A composition flow path extends 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 is biased closed by a biasing member contacting the breath operated valve at one end. A bung in the inner housing is positioned in an opening in the inner housing to support the end of the biasing member opposite to the breath operated valve. A rigid outer housing surrounds the inner housing and supports the bung.
