Abstract:
1. A capsule for the preparation of a coffee extract from coffee contained in the capsule and hot water injected under pressure in the capsule by a water injection device having blades extending along a circular path, the capsule comprising: a frusto-conical body comprising a rim, a sidewall and an inlet wall, the rim forms a flange; a lower delivery wall sealed to the rim of the body; a predosed amount of coffee in the capsule; wherein the inlet wall has a structure arranged for facilitating penetration by blades belonging to the water injection device, the structure comprises a portion of the inlet wall having a reduced thickness (t) compared to the thickness of the sidewall, the portion of the inlet wall having the reduced thickness is positioned along a radius (R wherein the body is a self-standing, integrally moulded piece extending by the rim and is made of polymer material; wherein the inlet wall that has the reduced thickness comprises reinforcement members extending locally on the inlet wall to ensure improved rigidity during perforation by the blades; wherein the predefined circular line of radius R wherein the reinforcement members are integral with the body and extend from the inlet wall to the sidewall of the body.
