Beverage maker for freshly brewed drinks - incorporates piston releasing perforated base to release excess pressure upwards to not affect coffee grains etc

摘要

The beverage maker which is used for freshly brewing coffee or tea etc comprises a cylindrical container (4) with a perforated base (19) and piston (21) wherein as the piston rises the hot water and coffee grains etc are supplied to the container through a valve in the piston and as the piston moves downwards the liquid coffee is pressed through the perforated base (19) which is subsequently released but only when the piston (21) has passed its base position and has opened so that the pressure in the container (4) is reduced to atmospheric pressure. The excess pressure in the container can thereby only escape up throught the piston which prevents the coffee residue from being forced out unevenly so that it can then be rinsed out with water or during the next brew.
