Abstract
An injection device with distal and proximal ends includes a housing, a needle-protecting sleeve that is longitudinally movable relative to the housing, a container holder that is longitudinally movable relative to the housing toward the proximal end from a non-delivery position to a delivery position, and a needle-protecting sleeve spring that is operatively coupled between the needle-protecting sleeve and the container holder such that the sleeve is longitudinally movable toward the distal end from an initial position to an activating position and toward the proximal end from the activating position to an end position. The sleeve spring is strained by a first amount when the sleeve moves from its initial position to its activating position, and by a second amount when the container holder moves from its non-delivery position to its delivery position.
