  • Publication number: 20080173182
    Abstract: A machine for the preparation of a hot drink with a water tank, a closed brewing chamber and a region for the accommodation of a cup. In order to minimize the size of the machine, to simultaneously prevent the production of germination and to save manufacturing and operating costs, the capacity of the water tank is rated such that the amount of water is only sufficient for one cup of hot drink so that the water tank is empty at the end of brewing.

  • Publication number: 20040159242
    Abstract: Described is a coffee machine (1) for preparing at least a first coffee beverage at a first brewing pressure and at least a second coffee beverage at a second brewing pressure, the second brewing pressure being higher than the first brewing pressure. The coffee machine is provided with a brewing means (5) which is connected via an outlet line (9) to a tap opening (1). A throttle means (12, 112) is provided in the outlet line (9) and is adjustable between a first and a second flow cross-section, the first flow cross-section being greater than the second flow cross-section. To simplify such a coffee machine in a constructionally simple way in terms of control, it is suggested that the throttle means (12, 112) should be made adjustable by the action of the brewing pressure.

  • Patent number: 4703686
    Abstract: Described is a coffee percolator for dispensing individual charges of freshly brewed coffee, which may also be employed, however, for satisfying a temporarily occurring increased demand. To this purpose the percolator is provided with a second outlet for dispensing the coffee into a storage container. In a preferred embodiment, two separate switching means are provided for actuation by the user for dispensing the coffee directly into a serving receptacle or into the storage container. This permits charges of different size to be preselected, so that a greater amount of coffee can be brewed for filling the storage container than would be required for filling a serving receptacle. The storage container is portable and provided with its own outlet, so that it can readily be carried to the site of use.
