The capsule according to the invention consists of a capsule body having a side wall and having a base which is integral with the side wall. The capsule comprises a lid that covers the capsule body in order to form a closed chamber, wherein said chamber contains a substance for preparing a beverage.
The capsule according to the invention consists of a capsule body having a side wall and having a base which is integral with the side wall. The capsule comprises a lid that covers the capsule body in order to form a closed chamber, wherein said chamber contains a substance for preparing a beverage. The base can be penetrated by a device arranged outside of the capsule in order to conduct a liquid through the chamber. The capsule body is made of plastic, wherein the base has a penetration area and a reinforcement area. A central area of the base is designed at the penetration area and the reinforcement area is arranged around the penetration area. The reinforcement area is designed as at least one recessed section in the base, said section(s) running substantially in the circumferential direction.

1. A capsule consisting of a rotationally symmetrical capsule body having a side wall and having a base which is realized integrally with said side wall as well as having a lid which covers the capsule body for forming a closed chamber which contains a substance for the preparation of a beverage, wherein, for conducting a liquid through the chamber, at least the base is penetrable at a penetration region of the base by way of a device which is arranged outside of the capsule, and wherein the base has a reinforcement region,wherein a central region of said base is realized as the penetration region,wherein said reinforcement region is arranged in a rotationally symmetrical manner around said penetration region, and wherein said reinforcement region is realized in the base as at least one portion-wise recess substantially in the circumferential direction,wherein said portion-wise recess has three wall portions which are inclined toward one another,wherein a first wall portion lies in a cutting plane, which extends along the longitudinal axis of the capsule body, substantially parallel to the longitudinal axis of the capsule body or encloses an angle with the longitudinal axis within the range of ±20°,wherein a second wall portion encloses a first external angle with the first wall portion within the range of between 35° and 55°,and wherein a third wall portion encloses a second external angle with the second wall portion within the range of between 35° and 55°. 2. The capsule as claimed in claim 1, wherein the portion-wise recess is realized in at least one of a step-shaped manner or an L-shaped manner in a cutting plane which extends along the longitudinal axis of the capsule body, wherein one arm of the L-shape lies substantially parallel to the longitudinal axis of the capsule body or encloses an angle with the longitudinal axis within the range of ±20°, wherein a second arm of the L-shape lies substantially at right angles to the longitudinal axis or encloses an arm angle with the longitudinal axis within the range of between 70° and 110°. 3. The capsule as claimed in claim 1, wherein the portion-wise recess has at least one face portion parallel to a cutting plane, which extends along the longitudinal axis of the capsule body, through the recess or the face portion with said cutting plane encloses an angle within the range of ±45°. 4. The capsule as claimed in claim 1, wherein the base has at least two portion-wise recesses. 5. The capsule as claimed in claim 4, wherein the base between the portion-wise recesses is realized as a triangular web. 6. The capsule as claimed in claim 1, wherein the capsule body consists of at least two polymer layers and is produced using a deep-drawing method. 7. The capsule as claimed in claim 6, wherein an outer layer of the capsule body consists of polyethylene. 8. The capsule as claimed in claim 1, wherein the lid is formed from at least one of an aluminum foil, a perforated foil or filter paper or arbitrary combinations thereof. 9. The capsule as claimed in claim 1, wherein the penetration region has a center indentation. 10. The capsule as claimed in claim 1, wherein the side wall of the capsule has at least two reinforcement ribs which are arranged on the outside substantially parallel to the longitudinal axis and which are spaced apart from one another along the circumference, wherein the capsule body including the capsule wall and the reinforcement ribs are realized integrally. 11. The capsule as claimed in claim 1, wherein the capsule body is realized as a truncated cone, wherein a truncated cone angle between the longitudinal axis and the side wall of the capsule is different in portions along the longitudinal axis. 12. The capsule as claimed in claim 10, wherein the capsule body has at least three portions with a different truncated cone angle. 13. A capsule body for a capsule as claimed in claim 1. 14. The capsule as claimed in claim 1, wherein the capsule is enclosed in a substantially air-tight manner by a covering. 15. A system including a capsule which is filled with a substance as claimed in claim 1 and a beverage production apparatus, wherein the beverage production apparatus has a capsule holder for accommodating a capsule, as well as a device for penetrating a base of the capsule and for supplying a liquid into the capsule for extracting the substance for producing a beverage, wherein the beverage can be discharged through a lid of the capsule. 16. The capsule as claimed in claim 1, wherein the capsule body consists of at least three layers, said layers consisting in each case of one of the following materials or of an arbitrary combination therefrom: polypropylene, polyethylene and ethylene vinyl alcohol,and wherein the capsule body is produced using a deep drawing method.
