1. A medicament delivery device, comprising:
a body,
a container carrier for retaining a medicament container within the body, the container carrier slidably disposed in the body,
a sleeve slidably coupled to the body, and
a piston rod coupled to the body and the container carrier, the piston rod coupled to the body in a manner preventing relative movement between the piston rod and the body,
wherein the piston rod and the container carrier are configured to provide a feedback as the container carrier moves from a first position to a second position relative to the body,
wherein the container carrier comprises one or more radially inwardly biased legs adapted to engage a ratchet toothing on the piston rod in such a manner that the container carrier can move in a proximal direction but is prevented from moving in a distal direction relative to the piston rod.
