Abstract
An espresso machine has an underside provided with a brewing head into which a strainer holder having a handle can be inserted from below with a strainer inserted in the holder. The brewing head has slots and the strainer holder includes corresponding lugs that fit through the slots so that the strainer holder can be released from or locked to the brewing head by a pivoting movement of the strainer holder around an axis of the brewing head which places the lugs in or out of alignment with the slots, respectively. A positioning ring has a top end rotatably secured to the brewing head and a cutout that is open toward the bottom end of the positioning ring for receiving the handle of the strainer holder. A mechanism cooperating between the positioning ring and the brewing head locates the positioning ring in an initial position so that when the cutout in the positioning ring receives the handle of the strainer holder, the strainer holder can be raised and inserted into the brewing head with the lugs on the strainer holder in alignment with the slots in the brewing head.
