The present invention relates to an espresso brewing-head unit comprising locking member for detachable attachment to a brewing unit of an espresso machine. A filter for an espresso machine is meant to be improved in a general manner. To this end, the espresso brewing-head unit comprises a pot-shaped coffee receiving container consisting of a plastic material, whose bottom is provided with a filter plate having coffee exit openings and whose upper edge portion in the side wall has firmly embedded therein a substantially surrounding reinforcement ring of a stable material, preferably metal, the reinforcement ring comprising attachment portions which are part of the locking member.

Espresso brewing-head unit

The present invention relates to a permanent espresso filter insert for insertion into an espresso machine, the insert comprising a substantially flat filter disc which is penetrated by a plurality of filter openings substantially in the flow direction of the medium to be filtered, with a perforated disc being designed and arranged downstream of the filter disc in flow direction in such a manner that the medium to be filtered is swirled and deflected to an increased extent. With the permanent espresso filter insert of the invention, it is possible to improve the formation of the head or cream also in espresso machines having low working pressures.
