Safety cover for coupling with an injection device

A safety cover for coupling with an injection device, the safety cover comprising:

• a base;
• a cover including an outer housing and an inner housing;
• and
• a hinge,
• wherein the base includes a needle mount which is configured for directed receiving of an injection needle along a receiving axis of the needle mount,
• wherein the outer housing is coupled with the inner housing in a coaxial arrangement relative to a longitudinal axis of the cover and mounted at the inner housing, at least partially surrounding the inner housing,
• wherein the cover is connected by the hinge with the base, so that the cover is pivotable relative to the base about a pivot axis formed by the hinge and oriented perpendicular to the receiving axis so that that the cover is pivotable from an initial position in a first pivoting direction into a treatment position,
• wherein the longitudinal axis of the cover is aligned parallel to the receiving axis of the needle mount when the cover is in the initial position, so that the injection needle received in the needle mount is enclosed by the cover,
• wherein the longitudinal axis of the cover is pivoted relative to the receiving axis of the needle mount when the cover is in the treatment position, so that the injection needle received in the needle mount is available for use,
• wherein the outer housing is twistable relative to the inner housing at least in one rotation direction about the longitudinal axis of the cover,
• wherein the outer housing includes at least one first recess and the base includes at least one locking device corresponding with the at least one first recess
• wherein the at least one locking device projects radially outward relative to the receiving axis of the needle mount and is configured engage the at least one first recess by positive form locking and block a further twisting of the outer housing relative to the inner housing when the outer housing is in a locking position when the outer housing is twisted relative to the inner housing,
• wherein the at least one locking device of the base engages the outer housing by positive form locking at least when the outer housing is in a starting position which is assumed by the outer housing at least when the cover in the initial position, so that a twisting of the outer housing relative to the inner housing is blocked by the at least one locking device,
• wherein the cover is pivotable by the hinge about the pivot axis in a second pivoting direction that is opposite to the first pivoting direction, beyond the initial position of the cover into an end position of the cover, so that the outer housing is displaceable relative to the base and the cover is transferrable into the end position,
• wherein an engagement of the at least one locking device with the outer housing is terminated and a twisting of the outer housing relative to the inner housing is enabled when the cover is in the end position.
