Aseptic container closure having a hinge and a mouthpiece

A container closure comprising:

• a base part,
• a pouring area having a peripheral wall extending about a reference axis of the container closure and extending axially from the base part to a peripheral top edge of the pouring area surrounding a drinking opening,
• a cap part connected to the base part by a hinge and rotatable back and forth between a closed position and an open position about a pivot axis extending perpendicular to the reference axis, wherein the cap part has a base and a peripheral outer wall surrounding an inner surface of the base and extending axially from the base to a circumferential lower edge of the cap part, wherein the peripheral outer wall and the base of the cap part together surround and cover the pouring area in the closed position,
• wherein the cap part has an anchor wall which extends outside the peripheral outer wall at a radial distance from the peripheral outer wall and is rigidly connected to the lower edge of the cap part by a bridge of the cap part extending radially outwardly from the lower edge of the cap part, wherein, in the closed position, the anchor wall projects from the bridge in a direction opposite the base part and the hinge is connected to the anchor wall and extends from the anchor wall toward the base part, and
• wherein a channel is formed by the anchor wall, the bridge and a surface of the peripheral outer wall opposite the bridge, wherein the channel extends in a circumferential direction between two channel ends and is open in a direction opposite the base part between the channel ends, as well as in the circumferential direction at the two channel ends.
