摘要：A capsule for extraction of coffee comprises a thermoformed truncated cone-shaped plastic capsule body having an outlet side and an inlet side. A destructible inletsealing membrane (11) attached inside the capsule body closes an inlet opening (10). Acircumferential centring ramp (12) ends in an inwardly directed circumferential flange (9)forming the circular inlet opening (10). Said centring ramp (12) is designed to align saidmembrane (11) with the inlet opening (10) before welding it to the flange (9). Themembrane (11) has a diameter larger than the outer diameter of the flange (9), a circularedge (13) being bent upwards along the centring ramp (12) and at least partially coveringthe latter when welding the membrane to the second flange (9). Said circular edge formsa heat protecting layer between a hot sealing tool (14) and the centring ramp (12).
