1. A capsule for the preparation of beverages from soluble preparations after a liquid has been fed to said capsule, said capsule comprising: a dispensing wall and a dispensing wall lid portion that opens to form a dispensing opening for said beverage, said lid portion integrally connected to the dispensing wall at a fracture line, and a thickness of said dispensing wall in an area adjacently surrounding said lid portion is greater than a thickness of said dispensing wall adjacent side walls of the capsule,wherein said capsule includes means for repeatedly increasing and decreasing an area of said dispensing opening during dispensing the beverage from said capsule such that a cycle of increasing and decreasing the area of said opening repeats as long as the liquid is added to the capsule. 2. The capsule according to claim 1, wherein said means for repeatedly increasing and decreasing said area of said dispensing opening comprise hinge means. 3. The capsule of claim 2, wherein said hinge means are provided on the dispensing wall of the capsule in which said opening is formed, to impart an oscillating movement to said wall during said dispensing. 4. The capsule according to claim 2, wherein said hinge means are hinges that connect said dispensing wall lid portion to said dispensing wall, and said hinges bias said lid portion to return to an at least partially closed position after having been stressed into the open position before all the beverage has been dispensed. 5. The capsule according to claim 1, wherein at least part of said dispensing wall has a rigidity within a range of 10 to 55 N/mm measured by compression with a punch and deflection set to 3 mm. 6. The capsule according to claim 2, wherein said dispensing wall is inclined convergent towards said dispensing wall lid portion and wherein an angle of inclination of said wall towards said dispensing wall lid portion is within the range of 1 to 15 degrees. 7. The capsule according to claim 1 further comprising a filter element. 8. The capsule according to claim 7, wherein said filter element is spaced apart from a bottom wall of said capsule via a spacer. 9. The capsule according to claim 7, wherein said dispensing wall is configured to move outwardly relative to an interior of the capsule. 10. The capsule according to claim 3, wherein said hinge means are hinges connecting said dispensing wall lid portion to said dispensing wall, said hinges biasing said lid portion to return to an at least partially closed position after having been stressed into the open position before all the beverage has been dispensed. 11. The capsule according to claim 3 further comprising a filter element. 12. The capsule according to claim 2 further comprising a filter element. 13. A capsule for the preparation of beverages from soluble preparations after a liquid has been fed into said capsule, said capsule comprising: a dispensing wall including an outlet lid portion to form a dispensing opening for said beverage, said lid portion integrally connected to the dispensing wall at a fracture line, and a thickness of said dispensing wall in an area adjacently surrounding said lid portion is greater than a thickness of said dispensing wall adjacent side walls of the capsule, and wherein at least part of said dispensing wall has a rigidity within the range of 10 to 55 N/mm measured by compression with a punch and deflection set to 3 mm such that an area of the dispensing opening repeatedly increases and decreases during dispensing of the beverage and a cycle of increasing and decreasing the area of said opening repeats as long as the liquid is added to the capsule. 14. The capsule according to claim 13 further comprising a filter element. 15. A capsule for the preparation of beverages from soluble preparations after a liquid has been fed to said capsule, said capsule comprising: a dispensing wall and a dispensing wall lid portion which opens to form a dispensing opening for said beverage, said lid portion integrally connected to the dispensing wall at a fracture line, and a thickness of said dispensing wall in an area adjacently surrounding said lid portion is greater than a thickness of said dispensing wall adjacent side walls of the capsule,wherein said capsule repeatedly increases and decreases an area of said dispensing opening during dispensing the beverage from said capsule such that a cycle of increasing and decreasing the area of said opening repeats as long as the liquid is added to the capsule, anda hinge connects the dispensing wall lid portion to the dispensing wall and biases the dispensing wall lid portion toward a closed position. 16. A capsule for the preparation of beverages from soluble preparations after a liquid has been fed to said capsule, said capsule comprising: a dispensing wall and a dispensing wall lid portion that opens to form a dispensing opening for said beverage, said lid portion integrally connected to the dispensing wall at a fracture line, a thickness of said dispensing wall in an area adjacently surrounding said lid portion is greater than a thickness of said dispensing wall adjacent side walls of the capsule, and said dispensing opening is formed when pressurized liquid inside said capsule pushes said lid portion outwardly of said capsule,wherein said capsule repeatedly increases and decreases an area of said dispensing opening during dispensing the beverage from said capsule such that a cycle of increasing and decreasing the area of said opening repeats as long as the liquid is added to the capsule. 17. The capsule according to claim 16 further comprising a filter element.
