1. A capsule for the preparation of a beverage in a beverage preparation device comprising a cup-like body, a cover for closing the cup-like body; a flange for the cover to seal thereon; the cup-like body being shaped from a paper-based sheet to form a cavity wall containing beverage ingredients and an inner flange portion extending outwardly from the cavity wall; wherein the flange further comprises an outer flange portion formed of moulded polymer-based material comprising at least a loop shaped recess enabling the inner flange portion to be received in and the polymer-based material of the outer flange portion to seal at least partially against a lower surface of the inner flange portion oriented in the direction (B) towards the cavity wall and against the outer edge of the inner flange portion. (15) (0)

2. The capsule according to claim 1, wherein the cavity wall is revolutionary symmetrical and the recess is annular. (0)

3. The capsule according to claim 1, wherein the outer flange portion prolongs the inner flange portion both in outward radial direction (R_E) and in axial direction (C). (0)

4. The capsule according to claim 1, wherein the region of the outer flange portion extending outwardly (radially) beyond the inner flange portion is thicker than the lower part of the outer flange portion sealing against the lower surface of the inner flange portion. (0)

5. The capsule according to claim 1, wherein the outer flange portion forms an outermost relief of longest axial dimension (L) compared to the axial dimension (L₀) of the rest of the flange. (0)

6. The capsule according to claim 1, wherein the outer flange portion further extends inwardly (in direction R_I) by an upper part which seals against the upper surface of the inner flange portion. (1) (0)

8. The capsule according to claim 1, wherein the outer flange portion forms a step-like recess which is arranged in open fashion upwardly towards the cover. (1) (0)

10. The capsule according to claim 1, wherein the paper-based sheet of the body comprises at least one oxygen barrier layer. (1) (0)

11. The capsule according to claim 1, wherein the paper-based sheet of the body comprises at least one sealing layer oriented towards the cavity. (0)

12. The capsule according to claim 1, wherein the cover is a paper-containing sheet and optionally the cover comprises a gas barrier layer. (0)

13. The capsule according to claim 1, wherein the cover comprises a sealing layer oriented (in direction B) towards the cavity or bottom of the body. (0)

14. The capsule according to claim 1, wherein the polymer-based material for the outer flange is an injection-mouldable thermoplastic material or elastomeric-thermoplastic material (TPE) selected from a group consisting of polyethylene (PE), high-density polyethylene (HDPE), polypropylene, polyethylene terephthalate (PET) and combinations thereof. (0)

15. The capsule according to claim 1, wherein the moulded polymer-based material is filled with reinforcing material. (0)

16. The capsule according to claim 1, wherein the outer portion of flange comprises an identification code. (1) (0)

17. The capsule according to claim 1, wherein the beverage ingredients are selected from the group consisting of ground coffee, soluble coffee, coffee beans, leaf tea, soluble tea, dairy products, cocoa, chicory, barley, culinary aid, soup ingredient, infant formula and combinations thereof. (0)
