A multipart cover made of paper material, comprising a base body which includes a cover plate and a circumferential cover collar extending from the cover plate, wherein the cover collar and the cover plate are shaped from a one piece paper material cut-out, wherein the cover collar, in a condition placed onto a container to be closed, surrounds and rests against an upper rim of the container to be closed, and a reinforcement ring which surrounds the cover collar at least sectionally on a radially exterior side of the cover collar, wherein the cover collar includes at least one bead encircling the cover collar in a circumferential direction, wherein the bead is disposed at a constant distance to the cover plate as viewed in an elevation direction, wherein the bead extends radially inwards relative to a portion of the cover collar, wherein a space is located between the cover collar and the reinforcement ring at the bead, wherein the reinforcement ring is connected to the cover collar by adhesive bonding or sealing above and below the bead extending along a periphery of the reinforcement ring, and wherein the reinforcement ring is exclusively arranged on the radially exterior side of the cover collar.
A multipart cover made of paper material comprising:
- a one piece integral base body having a cover plate and a circumferential cover collar extending from and being connected to the cover plate;
- the cover collar surrounding and resting against an upper rim of a container to be closed when placed onto the container to be closed;
- and
- a reinforcement ring separate from, abutting and surrounding the cover collar on a radially exterior side of the cover collar;
- wherein the cover collar includes at least one bead encircling the cover collar in a circumferential direction, the bead is disposed at a constant distance to the cover plate as viewed in an elevation direction, the bead extends radially inwards relative to a portion of the cover collar, an empty space is located between the cover collar and the reinforcement ring at the bead, and the reinforcement ring is connected to the cover collar by adhesive bonding or sealing above and below the bead extending along a periphery of the reinforcement ring;
- and
- wherein the reinforcement ring is exclusively arranged on the radially exterior side of the cover collar.
