  • automatic means 23 for expelling the pod 4 are comprised and are provided on each one of the infusion chamber parts 8 and 11 for the separation and expulsion of the pod 4 from the infusion chamber parts 8 and 11 following their mutual spacing by way of the translation means 9 described earlier.
  • the automatic expulsion means 23 comprise, for each infusion chamber part 8 or 11 , a cap-like element 24, which is made of a nonstick elastically deformable material which is hygienically adapted for making contact with food.
  • each cap-like element 24 is fitted on a respective infusion chamber part 8 or 11 so as to define an elastic membrane 25 which is directed toward the other infusion chamber part 8 or 11 and delimits the internal volume of each infusion chamber part 8 or 11.
  • the elastic membranes 25, by deforming elastically due to the approach of the infusion assembly 5 to the abutment element 10, with the pod 4 interposed, adhere to the inner surfaces 22 of the two infusion chamber parts 8 and 11, and once the spacing of the infusion assembly 5 from the abutment element 10 has occurred, by recovering their initial geometry they expel the pod 4 from the infusion chamber 12, leaving it free to fall into the discharge channel 15.
  • the two cap-like elements 24 also act as gaskets for the two infusion chamber parts 8 and 1 1, ensuring a correct seal of the entire dispensing assembly 1.
