<p>The device has a water inlet and a capsule-boring unit arranged at the interior of a cone shaped capsule housing (5). The housing is sized so as to partially deform a capsule (1) consisting of a material that is deformable in contact with hot water, such that the capsule is retained in the housing after the capsule is contacted with the hot water. A harpoon type relief is placed at an internal wall of the housing. A recess (6) i.e. annular groove, is formed on the internal wall of the housing, and is occupied by a lightly deformable element (7) e.g. spring.</p> |
