1. An autoinjector for automatically injecting an active agent, the autoinjector comprising:
an elongated casing;
an injection needle axially shiftable in the casing and connected to an active agent container;
a piston shiftable in the active agent container, to deliver the active agent;
a needle tube shiftable relative to the casing and configured to permit the injection needle to protrude therefrom; and
a resilient or elastic latching member, wherein in a latching position, the latching member prevents the active agent container from being shifted with respect to the casing, and wherein the latching member is movable to a release position,
wherein the container is axially shiftable in the casing by a spring force, and
wherein when the needle tube is shifted into the casing, the latching member is forced away from the latching position and thus freeing a travel path for an axial shifting of the needle.
