If the capsule has a vertical extraction direction, and therefore the sealing element is oriented horizontally, all the coffee seals the gap uncontrollably. This can cause irregular deformations of the sealing element that lead to a worsening of the sealing at this point and increase the effort required to close the capsule holder. This same effect is more pronounced in the case of vertical extraction machines, since all the coffee accumulates by gravity in the lower part of the capsule.
  • the separation means ensure that a significant amount of infusion product can accumulate in the recess provided below the sealing element that can cause the negative effects observed in the state of the art capsules in which the recess is part of the inner chamber of the capsule.
