  • Patent number: 7032507
    Abstract: Device and method for brewing coffee comprises a body connected to a container for allowing the formation of a dispersion of flavor-containing materials and liquid and the extraction of the flavor-containing materials to produce a liquid extraction, a porous filter connected to the body and having a first surface for contacting the dispersion, filtration openings for allowing the liquid extraction in the dispersion to pass through but blocking the flavor-containing materials and a second surface for receiving the liquid extraction, and a flow facilitator having a selective opening adapted to allow air to pass through but restrict the flavor-containing materials from passing through. The body and porous filter are adapted to allow the container to be tilted to generate a liquid head to act on the first surface of porous filter to drive the liquid extraction through the porous filter to produce a beverage.

    Abstract: With respect to a filter with a fastening device for a coffee-making apparatus of the type where water is brought to a boil in a closed container, whereupon the water is pressed through a riser pipe into a funnel, where boiling water extracts aromas and flavour from the ground coffee, whereupon the finished coffee beverage is filtered back into the closed container through a filter placed at the outlet of the funnel, where the filter is fastened by means of a fastening device which reaches through the riser pipe, the objective is to provide a filter where the aroma and flavour of the ground coffee is exploited as well as possible and where the filter offers a comparatively large filter surface for the finished coffee, and where the filter can easily be removed from the funnel and cleaned with a view to further coffee-making. Moreover, the filter must be easily replaceable by dismantling the handle and locking clip and fitting these on a new filter.

The centrally located chamber is located above a heating unit, such as a standard electric resistance heater, a halogen lamp or a heater with one or more thick film conductors, and the heated liquid flows upwardly through a riser to be distributed over a supply of comminuted coffee beans or tea leaves in a removable filtering unit which has an outlet for admission of freshly brewed coffee or tea into the outer chamber. A cover above the filtering unit is threadedly connected to the upper end of the housing to ensure that the interior of the housing can be maintained well above atmospheric pressure without risking escape of hot water or steam. The device for uniformly distributing heated water in the filtering unit can constitute a nozzle or a foraminous top wall above the supply of flavoring agent.

  • Patent number: 4765896
    Abstract: Beverage brewing funnel combination for supporting scrunchable disposable filters in either their non-scrunched full or normal capacity condition or in a scrunched reduced-capacity condition. The combination is formed by a funnel and a removable skeleton-like insert. The interior bottom surface of the funnel is inclined or dished toward a drain aperture and has a plurality of upstanding ribs which maintain a wet disposable filter out of adhering contact with the bottom surface when the funnel is used without the removable insert to support a disposable filter in its non-scrunched condition. When the insert is nested within the funnel it supports the disposable filters in their scrunched condition and preferably out of contact with the bottom surface of the funnel as well as the sidewall surface thereof.

  • Patent number: 4751875
    Abstract: Liquid beverage equipment for producing a consumable liquid beverage or a liquid beverage concentrate which can be mixed with a liquid diluent such as water to form a consumable beverage. The equipment includes a container for receiving a quantity of liquid such as lot water and a removable receptacle having a quantity of flavor imparting material therein with the receptacle being constructed to enable direct contact between the liquid and the flavor imparting material to form a liquid beverage which then can be removed from the container. The receptacle and depleted flavor imparting material are then removed from the container for disposal of the depleted flavor imparting material. The liquid fills the container to a predetermined level to remain in contact with the flavor imparting material for a predetermined time period before draining the liquid from the container.

  • Patent number: 4328740
    Abstract: In accordance with the present invention, there is provided a coffeemaker with a variable brew strength apparatus which comprises a base which contains a water reservoir and a heater and which supports a coffee carafe. The base supports a variable brew strength apparatus directly over the coffee carafe. The variable brew strength apparatus includes a water restrictor member which is rotably mounted on the cover of a coffee basket member. The water restrictor member and the coffee basket member, in combination, form a valve which either admits heated water to an inner basket which is mounted in the coffee basket and which contains ground coffee, or causes a portion of the heated water to bypass the inner basket and enter the coffee basket to mix with and dilute coffee brewed in the inner basket. The coffee basket supports a special coffee scoop which has a tabular indicia relating the number of cups of coffee desired, the brew strength desired, and the number of scoops of coffee required.

  • Patent number: 4181071
    Abstract: This disclosure describes a teapot and a cover therefor. The cover is hollow and radiused at the top tapering to a slightly larger radius at the bottom. The hollow cover is sufficiently large and operates as a food warmer when the perforated disc is placed across the opening of the tea making chamber. The perforated disc allows the penetration of steam into the hollow cover of the teapot creating a food warmer, thus conserving energy by making use of otherwise unused steam. The teapot having a removable circular band, with attached teabag holders, which fits within the interior of the tea making chamber is of a size slightly less than the interior diameter of the tea making chamber and allows for use of the standard teabag without the string and label being attached, thus eliminating the teabag string from falling into the infusing substance during the infusing process and further eliminating the dangers of the teabag label coming in direct contact with the heating source.

  • Patent number: 4119019
    Abstract: A funnel-shaped receptacle is temporarily positioned on the top of a coffee-making machine with its bottom outlet positioned to discharge into the heater tank of the machine. The interior of the receptacle is spanned by a disposable activated carbon filter and below the filter is a container of screen material filled with soluble phosphate granules. Replenishing water poured through the receptacle is first purified by the filter and is then treated with the dissolved phosphate to prevent calcium formation and corrosion in the heater tank.
