ABSTRACT:
A bubble-forming sleeve for an espresso coffee maker includes a generally vertical sleeving portion which has a central bore formed therethrough and which is sleeved fixedly on a nozzle that is fixed on an end of a vapor tube of the coffee maker in such a manner that a liquid-tight seal is established between the nozzle and the sleeving portion, and a mixing portion which is attached around a lower end portion of the sleeving portion and which is immersed entirely into the beverage within the container. The mixing portion has a downwardly opened mixing chamber which is located under and which is communicated fluidly with the central bore of the sleeving portion so as to permit vapor flow from the nozzle into the chamber, and a generally vertical air passage unit which is communicated fluidly with the chamber at a lower end and with an exterior of the sleeve at an upper end. Heated vapor flows downward from the chamber so as to heat the beverage within the container and so as to draw the beverage in the container into the chamber via the air passage unit, thereby forming bubbles of the beverage in the container.
