Cup-shaped body for a capsule for preparing a beverage

Cup-shaped body for a capsule, the capsule containing an extractable product and being arranged for preparing a consumable beverage in a beverage preparation device, the cup-shaped body comprising:

• a circumferential wall around a reference axis,
• a first end wall closing the circumferential wall at a first end of the cup-shaped body, and
• an open second end, opposite the first end, allowing for filling the cup-shaped body through said open second end with said extractable product so as to form said capsule when the thus filled cup-shaped body is closed with a second end wall at said open second end;
• wherein:
• for reference purposes in relation to the cup-shaped body, a first direction along said reference axis is defined as being directed from the first end towards the open second end, and a second direction along said reference axis is defined as being opposite to the first direction,
• the first end wall comprises a portion being deepened in the first direction, said deepened portion thus forming a first recessed space on the second direction side of the first end wall,
• the first end wall comprises a projection protruding from said deepened portion into said first recessed space,
• the cup-shaped body is formed such that identical specimens of the cup-shaped body are slidable, along said reference axis, into one another so as to form a stack of said specimens, said slidability being such that a first specimen of said specimens can be slided in the second direction and with its first end in front through the open second end of a second specimen of said specimens and into said second specimen, and
• the deepened portion of the first end wall is formed to comprise abutment structure having an abutment condition in which the extent of said slidability of said first specimen into said second specimen is limited by abutment of said abutment structure of said second specimen with the first end wall of said first specimen.
