A capsule for preparing infusion beverages comprising: [a] a containing body with a side wall and an end wall, said containing body defining a longitudinal direction, and [b] a cover, [c] said containing body and said cover being connected to each other at said side wall to form an inner chamber for containing an infusion product, [d] said end wall having: [i] a central section, [ii] an outer section arranged around said central section, and [iii] a deformation section connecting said central and said outer sections (10, 12) such that said central and said outer sections (10, 12) are movable relative to each other via said deformation section for moving said capsule between: - a closed position, in which said central section is remote from said inner chamber, and - an open position, in which said central section is near to said inner chamber, and [iv] a first opening for extracting said infusion beverage, [e] said capsule further comprising a sheet-like closing layer arranged adjacent to said end wall for closing said inner chamber from said first opening for extraction, said closing layer having a bearing side and a perforation side, and [f] perforation members, arranged in said inner chamber adjacent to said perforation side of said closing layer to perforate said closing layer when said capsule is in said open position, characterized in that it further comprises: [g] an inner wall arranged adjacent to said closing layer and crosswise to said longitudinal direction to divide said inner chamber into an infusion chamber and an extraction chamber, said inner wall comprising a plurality of second openings fluidly connecting said infusion chamber with said extraction chamber, and [h] receiving openings adapted to receive said perforation members, arranged adjacent to said bearing side of said closing layer, and [i] said bearing side of said closing layer being arranged relative to said end wall and said inner wall such that, when said capsule is in said open position, said bearing side of said closing layer bears respectively against one of said inner wall or said end wall, in order for said perforation members to cooperate with said receiving openings and perforate said closing layer, said receiving openings being correspondingly arranged on one of said inner wall or said end wall. [a] a containing body with a side wall and an end wall, said containing body defining a longitudinal direction, and [b] a cover, [c] said containing body and said cover being connected to each other at said side wall to form an inner chamber for containing an infusion product, [d] said end wall having: [i] a central section, [ii] an outer section arranged around said central section, and [iii] a deformation section connecting said central and said outer sections (10, 12) such that said central and said outer sections (10, 12) are movable relative to each other via said deformation section for moving said capsule between: - a closed position, in which said central section is remote from said inner chamber, and - an open position, in which said central section is near to said inner chamber, and [iv] a first opening for extracting said infusion beverage, [i] a central section, [ii] an outer section arranged around said central section, and [iii] a deformation section connecting said central and said outer sections (10, 12) such that said central and said outer sections (10, 12) are movable relative to each other via said deformation section for moving said capsule between: - a closed position, in which said central section is remote from said inner chamber, and - an open position, in which said central section is near to said inner chamber, and - a closed position, in which said central section is remote from said inner chamber, and - an open position, in which said central section is near to said inner chamber, and [iv] a first opening for extracting said infusion beverage, [e] said capsule further comprising a sheet-like closing layer arranged adjacent to said end wall for closing said inner chamber from said first opening for extraction, said closing layer having a bearing side and a perforation side, and [f] perforation members, arranged in said inner chamber adjacent to said perforation side of said closing layer to perforate said closing layer when said capsule is in said open position, characterized in that it further comprises: [g] an inner wall arranged adjacent to said closing layer and crosswise to said longitudinal direction to divide said inner chamber into an infusion chamber and an extraction chamber, said inner wall comprising a plurality of second openings fluidly connecting said infusion chamber with said extraction chamber, and [h] receiving openings adapted to receive said perforation members, arranged adjacent to said bearing side of said closing layer, and [i] said bearing side of said closing layer being arranged relative to said end wall and said inner wall such that, when said capsule is in said open position, said bearing side of said closing layer bears respectively against one of said inner wall or said end wall, in order for said perforation members to cooperate with said receiving openings and perforate said closing layer, said receiving openings being correspondingly arranged on one of said inner wall or said end wall.
