1. A device in combination with a capsule containing extraction material or an extract, said device being configured to discharge an extraction product from the capsule and comprising: a supporting surface for the capsule,at least one perforation element which projects from the supporting surface and comprises a perforation edge, and,at least one retaining web that projects from the supporting surface, and comprises a non-cutting edge and prevents a wall of the capsule from bearing against the supporting surface in an area surrounding the retaining web by the wall of the capsule bearing against said non-cutting edgewherein the supporting surface is defined by a sieve support, which is flat at least in sections and has at least one passage opening, and a sieve element, which is mounted flat on the sieve support and covers the passage opening, wherein an extraction product is capable of being discharged from the capsule through said sieve element, the said extraction product emerging from the capsule through an opening that is produced by the at least one perforation element; the retaining web is arranged in relation to a perforation edge of the perforation element such that the retaining web prevents a wall of the capsule from bearing against the supporting surface in an area surrounding the perforation edge, andwherein the retaining web butts against a perforation edge part that forms the perforation edge or is integrally formed with said perforation edge part, and wherein the retaining web is offset with regard to a perforation direction in comparison to the perforation edge. 2. A device according to claim 1, wherein the perforations in the sieve element comprise a diameter of between 0.1 mm and 0.3 mm. 3. A device according to claim 1, wherein the retaining web is designed to run parallel to a perforation direction. 4. A device according to claim 3, wherein the retaining web protrudes from the supporting surface by a height that, measured perpendicular to the support surface, decreases as a distance from a perforating edge of the perforation element increases. 5. A device in combination with a capsule containing extraction material or an extract, said device being configured to discharge an extraction product from the capsule and comprising: a supporting surface for the capsule,at least one perforation element that projects from the supporting surface and comprises a perforation edge for perforating the capsule, and,at least one retaining web that projects from the supporting surface, and comprises a non-cutting edge and prevents a wall of the capsule from bearing against the supporting surface in an area surrounding the retaining web by the wall of the capsule bearing against said non-cutting edge,wherein the supporting surface is defined by a sieve support, which is flat at least in sections and has at least one passage opening, and a sieve element, which is mounted flat on the sieve support and covers the passage opening, wherein an extraction product is capable of being discharged from the capsule through said sieve element, the said extraction product emerging from the capsule through an opening that is produced by the at least one perforation element; and wherein the retaining web is integrally formed on a support to which the sieve support is fastened, and wherein the retaining web extends through the sieve support and projects from the supporting surface. 6. A device according to claim 1, wherein the perforation element comprises the form of a metal sheet protruding from the supporting surface, and wherein the metal sheet is bent or composed of a plurality of sheet metal pieces that are positioned at an angle relative to one another. 7. A device for puncturing a capsule, which capsule comprises an extraction material for brewing a beverage, by perforating a wall of the capsule, the device comprising: a plate-like base element that forms a supporting surface for the capsule, the plate-like base element comprising a plurality of through openings for a liquid to flow through the plate-like base element into the capsule or from the capsule, said plate-like base element including a main portion that includes said supporting surface and extending portions that extend outwardly from peripheral edges of said supporting surface whereby peripheral edges of said main portion are defined by the peripheral edges of the supporting surface and peripheral edges of said extending portions, andwherein the extending portions are folded at an angle so as to project away from the supporting surface and thereby form a plurality of perforation elements that are integral with the plate-like base element and project from the peripheral edges of the supporting surface such that the peripheral edges of the main portion are defined solely by the peripheral edges of the supporting surface,the perforation elements each comprising a sharpened perforation edge projecting away from the supporting surface. 8. The device according to claim 7, wherein the extending portions are folded so that the perforation elements are at an angle of between 80° and 90° to the supporting surface. 9. The device according to claim 7, wherein the perforation elements are approximately perpendicular to the supporting surface. 10. The device according to claim 7, wherein the supporting surface is essentially rectangular in shape and has four corners, and wherein one of the perforation elements is disposed adjacent to each corner of the supporting surface. 11. The device according to claim 7, wherein a number of the through openings corresponds to a number of the perforation elements. 12. The device according to claim 7, wherein each perforation element comprises a piercing tip. 13. The device according to claim 7, wherein the plate-like base element integral with the perforation elements is made of a sheet metal. 14. The device according to claim 7, wherein the perforation edges are at an angle to the supporting surface. 15. In a combination of an extraction apparatus with a capsule, the capsule comprising an extraction material for brewing a beverage by means of the extraction apparatus by perforating a wall of the capsule, injecting a liquid into the capsule and discharging a resulting extraction product as a beverage, a device for perforating the wall of the capsule, the device comprising:a plate-like base element that forms a supporting surface for the capsule, the plate-like base element comprising a plurality of through openings for a liquid to flow through the plate-like base element into the capsule or from the capsule, said plate-like base element including a main portion that includes said supporting surface and extending portions that extend outwardly from peripheral edges of said supporting surface whereby peripheral edges of said main portion are defined by the peripheral edges of the supporting surface and peripheral edges of said extending portions,wherein the extending portions are folded at an angle to project away from the supporting surface and thereby form a plurality of perforation elements that are integral with the plate-like base element and project from the peripheral edges of the supporting surface such that the peripheral edges of the main portion are defined solely by the peripheral edges of the supporting surface,the perforation elements each comprising a sharpened perforation edge projecting away from the supporting surface. 16. An extraction apparatus configured to prepare individual portions of a beverage from an extraction material that is packaged in a capsule, said extraction apparatus comprising a device for puncturing a capsule, which capsule comprises an extraction material for brewing a beverage, by perforating a wall of the capsule, the device comprising: a plate-like base element that forms a supporting surface for the capsule, the plate-like base element comprising a plurality of through openings for a liquid to flow through the plate-like base element into the capsule or from the capsule, said plate-like base element including a main portion that includes said supporting surface and extending portions that extend outwardly from peripheral edges of supporting surface whereby peripheral edges of said main portion are defined by the peripheral edges of the supporting surface and peripheral edges of said extending portions, andwherein the extending portions are folded at an angle to project away from the supporting surface and thereby form a plurality of perforation elements that are integral with the plate-like base element and project from the peripheral edges of supporting surface such that the peripheral edges of the main portion are defined solely by the peripheral edges of the support surface,the perforation elements each comprising a sharpened perforation edge projecting away from the supporting surface.
