Abstract
A medicament delivery device comprises a housing, a needle, a needle cover, a needle cover biasing member, and a needle cover retaining mechanism. The needle cover is axially movable between an extended position and a retracted position. The needle cover biasing member is configured to bias the needle cover axially in a distal direction towards the extended position. The needle cover retaining mechanism is configured to be moved between a first state, in which the needle cover retaining mechanism is disengaged from the needle cover such that the needle cover is moveable in the distal direction under a force of the needle cover biasing member, and a second state, in which the needle cover retaining mechanism is configured to engage the needle cover and prevent distal movement of the needle cover under the force of the needle cover biasing member, when the needle cover is in the retracted position.
