1. An injection device with a longitudinal axis, comprising:
a housing for receiving a product container, wherein the product container includes an injection needle fixedly connected thereto and a needle shield cap detachably arranged on the product container, the needle shield cap enclosing the injection needle and sealing the injection needle from the environment in a sterile manner; and
a cap detachably connected to a distal end of the housing, wherein the cap comprises an engagement element for removing the needle shield cap from the product container when the cap is removed from the injection device, wherein the engagement element is deformable such that the engagement element is movable from a spaced-apart position in which the engagement element is radially spaced from the needle shield cap to an engagement position in which the engagement element is in an engagement with the needle shield cap, wherein the engagement element is deformed during cap removal,
wherein the cap comprises a sleeve element, the sleeve element comprising a recess having a distal edge and a proximal edge, wherein in the spaced-apart position, the engagement element extends from an interior of the sleeve element through the recess and rests on the distal edge of the recess at an exterior of the sleeve element, and wherein the engagement element is moved to the engagement position by the proximal edge of the recess.
