Lid element and closure assembly for a beverage container

A closure assembly for a beverage container, comprising:

• a lid;
• and
• a closure arranged on the lid for closing an opening;
• wherein the lid comprises a lid panel with the opening, a folded rim extending around the lid panel in a circumferential direction for connecting the lid to the beverage container, and a damping bead extending circumferentially between the folded rim and the lid panel;
• wherein the lid comprises an outside and an inside;
• wherein the opening comprises an opening rim and an opening plane formed by the opening rim;
• wherein the lid further comprises a connecting region adjacent the opening rim;
• wherein the lid extends at least partially at a slope angle;
• wherein the slope angle can be determined in a cross-section, the cross-section being perpendicular to the opening plane and the opening rim;
• wherein the slope angle is measured between the opening plane and a tangent lying against either the outside of the lid or the inside of the lid;
• wherein the slope angle is more than zero angular degrees;
• wherein the opening rim forms a sealing face forming a gas-tight seal against an environment;
• wherein the closure is arranged on the lid from the inside and extends at least partially over the opening to the outside;
• wherein the connecting region adjoins the opening rim in a radial direction at a first portion;
• wherein the first portion extends at the slope angle;
• and
• wherein the first portion has an extent of at least 0.2 millimeters in the radial direction.
