1. A container closure, comprising:
a retaining ring that extends around a reference axis of the container closure;
a cap part; and
a hinge that connects the retaining ring to the cap part, the cap part comprising an end plate, a circumferential wall that surrounds an inner surface of the end plate and a gripping projection that extends radially outward from the circumferential wall and extends axially at a spacing from the end plate, wherein the circumferential wall comprises a deformable region that is diametrically opposite the hinge and extends between the end plate and the gripping projection, wherein the deformable region comprises an engagement projection that protrudes radially inward, a lower wall portion arranged between the engagement projection and the gripping projection and an upper wall portion that is arranged between the engagement projection and the end plate, wherein a wall thickness of the upper wall portion and a wall thickness of the lower wall portion are such that elastic deformation of the deformable region allows for a radially outward movement of the engagement projection for more than fifty percent of a radial extension of the engagement projection,
wherein the deformable region is surrounded in the circumferential direction by two reinforcing regions of the circumferential wall that connect the gripping projection to the end plate, and
wherein each of the reinforcing regions has a wall thickness that is greater than both the wall thickness of the upper wall portion and the wall thickness of the lower wall portion.
