1. A method for visually indicating that a door of a medical injector device is open, the method comprising:
applying a closing force, which is greater than an opening force exerted on the door by a biasing element, to the door to move the door from a first position towards a closed position;
stopping the applying of the closing force to the door, wherein the door, when the closing force is stopped, is at a second position, which is between the closed position and a last 30 degrees of rotation towards the closed position; and
moving the door, as a result of stopping the applying of the closing force with the door at the second position and via the opening force exerted by the biasing element, from the second position to a perceptibly open position that visually indicates that the door is open, wherein:
the perceptibly open position of the door is less than a fully opened position of the door,
the fully opened position of the door is greater than a 30 degree rotation away from the closed position of the door, and
the opening force is exerted on the door by the biasing element only when the door reaches the last 30 degrees of rotation towards the closed position.
