  • Patent number: 5104666
    Abstract: The present invention consists of a single-dose espresso maker for preparing infusions in general, to be disposed of after being used. It consists of two glass-shaped containers, one of which contains water to be heated and the other of which, equipped with a filtering bottom wall, contains the infusion product; the mutually opposite mouths of both said containers are coupled with each other by grafting, with the interposition of a water-sealing disk-shaped element of pre-established strength, which can be broken by the pressure developed by heating water; and of at least one perforated disk-shaped element. After heating the water containing element, the pressure of generated water vapor causes the breakage of said sealing disk, enabling water to flow through the filter-container containing the infusion product and hence the desired infusion to be produced and fed to a container associated with the espresso maker.
