A container for re-suspending sedimented medicament comprises a reservoir for containing a suspension of particles in a liquid, a dispensing portion, and a sealing portion. The sealing portion is arranged to be in fluid communication with the reservoir via an orifice. The orifice is positioned between the dispensing portion and the sealing portion, and allows a turbulent flow of the liquid from the reservoir into the sealing portion to enable re-suspension of particles that have sedimented out of the liquid in the sealing portion.
