Annular section of a ring-shaped element

摘要

Ring section as part of a ring-shaped element, such as a ring, a drinking vessel or a bottle opening, a disk-like member, wherein the ring portion (1) a rotationally symmetrical basic body (2) with an axis of symmetry (12) and an outside diameter and the base body (2) on its one end face (3) and a closed protective edge element (9) is formed and on its other end face (4) is connected with the actual element, characterized in that at least two notches (13, 14, 31, 32) is provided,a. the notches (13, 14, 31, 32) is in side view of the first protective edge element (9) in the direction of the further end face (4) of the ring section (1),example, wherein the notch (13, 14, 31, 32) a lowest point (15) and on the basis of this lowest point (15) flank elements (16, 17) away from both sides in the direction of the rim member (9), which extend an asymptotic approach to the edge element (9) matching.
