Abstract
An injection device is presented having a housing, a container holder, a first and a second energy accumulating member arranged in the interior of the housing adapted to accumulate and store energy, a sleeve, a plunger holder operationally associated with said first energy accumulating member such that the plunger holder and the container holder are axially moveable in relation to the housing a predetermined distance towards the proximal end of the injection device from an initial position to a position following needle penetration, and a plunger rod being operationally associated with said second energy accumulating member such that the plunger rod is axially moveable in relation to the container holder, wherein in the initial position movement of the plunger holder is substantially inhibited by at least one first biasable member that recoils when being overlapped by an opening and/or recess of the sleeve such that the plunger holder is released.
