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. ## Claims ### Claim at position 1 1-23. (canceled) ### Claim 24 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 penetratable 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 a 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. ### Claim 25 (depends on 24) The capsule as claimed in claim 24, wherein said recess has at least two wall portions which are inclined toward one another. ### Claim 26 (depends on 25) The capsule as claimed in claim 25, wherein said 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°. ### Claim 27 (depends on 24) The capsule as claimed in claim 24, wherein the 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°. ### Claim 28 (depends on 24) The capsule as claimed in claim 24, wherein the 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°. ### Claim 29 (depends on 24) The capsule as claimed in claim 24, wherein the base has at least two recesses. ### Claim 30 (depends on 29) The capsule as claimed in claim 29, wherein the base between the recesses is realized as a triangular web. ### Claim 31 (depends on 24) The capsule as claimed in claim 24, wherein the capsule body consists of at least two polymer layers and is produced using a deep-drawing method. ### Claim 32 (depends on 31) The capsule as claimed in claim 31, wherein an outer layer of the capsule body consists of polyethylene. ### Claim 33 (depends on 24) The capsule as claimed in claim 24, wherein the lid is formed from at least one of an aluminum foil, a perforated foil or filter paper or arbitrary combinations thereof. ### Claim 34 (depends on 24) The capsule as claimed in claim 24, wherein the penetration region has a center indentation. ### Claim 35 (depends on 24) The capsule as claimed in claim 24, wherein the capsule wall 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. ### Claim 36 (depends on 24) The capsule as claimed in claim 24, wherein the capsule body is realized as a truncated cone, wherein a truncated cone angle between the longitudinal axis and the capsule wall is different in portions along the longitudinal axis. ### Claim 37 (depends on 35) The capsule as claimed in claim 35, wherein the capsule body has at least three portions with a different truncated cone angle. ### Claim 38 (depends on 24) A capsule body for a capsule as claimed in claim 24. ### Claim 39 (depends on 24) The capsule as claimed in claim 24, wherein the capsule is enclosed in a substantially air-tight manner by a covering. ### Claim 40 (depends on 24) A system including a capsule which is filled with a substance as claimed in claim 24 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.
