Abstract
A container closure including a retaining ring which extends around a reference axis of the container closure, a cap part and a hinge which connects the retaining ring to the cap part. The cap part has an end plate, an enclosing circumferential wall and a grip projection which extends radially outward from the circumferential wall, axially with a distance to the end plate. A deformable region of the circumferential wall extends diametrically opposite the hinge, between the end plate and the grip projection, and has a latching projection directed radially inward, a lower wall section which lies between the latching projection and the grip projection and an upper wall section which lies between the latching projection and the end plate.
Claims16
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.
