The invention claimed is: 1. A cartridge for a prepacked serving of coffee powder, said cartridge comprising: an essentially cylindrical side wall provided at its two ends with a first wall adapted to be acted upon by a pressurized hot-water supply means, said first wall being provided with predetermined weakened area to facilitate an action of the pressurized hot-water supply means, said predetermined weakened area comprise a thin area located approximately in a center of the first wall surrounded by a plurality of radial stiffening ribs formed on said first wall; and a second wall adapted to be acted upon by a brewed coffee dispenser, said wall being continuous and made of a thermoplastic material, wherein said cylindrical side wall and said first wall and said second wall are made of an essentially airtight material. 2. The cartridge of claim 1, wherein said first wall is provided with diffusion means for diffusing the flow of hot water. 3. The cartridge of claim 1, wherein said second wall has a channel for channelling the flow of brewed coffee. 4. The cartridge of claim 1, wherein the weakened area comprises a fracture area. 5. The cartridge of claim 1, wherein the weakened area comprises a pre-fracture line. 6. The cartridge of claim 1, wherein the weakened area is in the form of a pair of intersecting pre-fracture lines, located proximate a center of the first wall. 7. The cartridge of claim 1, wherein the cartridge is essentially airtight. 8. A dispensing unit adapted for use with the cartridge of claim 1, the unit comprising: pressurized hot-water supply means for supplying hot water and for forming a hole in a first wall at a top of a cartridge containing coffee; a brewing chamber; and a dispensing means for dispensing the brewed coffee, said dispensing means comprising perforating means for forming at least one hole in a second wall at a bottom of the cartridge, wherein said perforating means is adapted to puncture the second wall of the cartridge, while at the same time, forming a seal with lips of the second wall which surround the hole, thereby preventing fluid to be dispensed from the cartridge through the second wall until a defined pressure has built up inside said cartridge, at which point fluid is dispensed from around the perforation means in a space defined between an exterior surface of the perforation means and the hole in the second wall. 9. The dispensing unit of claim 8, wherein said perforating means is located on a back wall of the brewing chamber where there is a dispensing manifold communicating with a dispensing pipe. 10. The dispensing unit of claim 8, wherein said supply means comprises at least one mouth means for breaking through the first wall of said cartridge. 11. The dispensing unit of claim 8, wherein the hot-water supply means is located above the brewing chamber and the perforating means is located below the brewing chamber.
