A container (10) for a liquid medicament suspension, e.g. an insulin crystal suspension, has a tube (11) with a sealing piston (13), a cap (16), and a mixing element (20) which moves along the tube (11) to asist mixing the suspension. The element (20) is guided by the inner surface of the tube (11) and has restricted lateral movement but is free to move axially, for example, by tilting or end to end inversion of the container. Flow passages such as apertures and peripheral recesses are provided in the mixing element which can serve to promote turbulent flow. The containers are particularly suited for use as multi-dose cartridges for pen-like injection devices or for portable infusion devices whuich have piston-operating mechanisms to co-operate with the container piston.
