  • Publication number: 20120328750
    Abstract: The device, known as an extraction basket, sits at the bottom of the brewing apparatus' brewing chamber. The basket is inserted into the chamber prior to the addition of the flavor base and water to the chamber. The basket is depressed to the bottom of the chamber. The flavor base is then added to the chamber along with hot water, following the French press process of brewing. With a standard French press brewing apparatus, once the flavor base and hot water is added, a filtration piston is then inserted into the brewing chamber. After the allotted brewing time has passed, the filtration piston is depressed into the chamber. This pushes the spent flavor base to the bottom of the chamber, filtering the brewed beverage from the solid flavor base. As the solid flavor base is pushed to the bottom, the spent flavor base is compacted in the extraction basket which is located at the bottom of the brewing chamber.

  • Patent number: 8313644
    Abstract: A portable vessel for fluids has an integrated filtration system. A pressing assembly fitted to the vessel includes a stopper, a rod having a top end and a filtration assembly. A vessel top receives the pressing assembly such that the rod of the pressing assembly is slidably attached to a bearing of the vessel top. A gasket attached to the filtration element maintains a seal between the inner surface of the vessel and an outer perimeter of the filtration assembly and the orientation of the rod is maintained by the gasket and the bearing. In use, pressure applied to the pressing assembly drives the filtration assembly through the vessel causing water to be filtered as it passes through the filter element.

    Abstract: A press and sip device including a straw and sieve coupled together to permit pressing solid particles to infuse flavor into a freshly brewed beverage consumable from the container in which it was prepared. The straw and sieve unit can be used in containers of various sizes through the use of gasket attachments. The sieve is provided with openings that allow the beverage to receive flavor from the solid particles while maintaining the particles separate from the beverage when the beverage is consumed. The straw is provided with apertures in the side wall of the straw that limit intake of beverage to the liquid above the sieve separated from the solid particles. The device is contemplated as having detachable elements to facilitate cleaning and storage.

  • Patent number: 7437990
    Abstract: An all-in-one beverage container for providing a mixed beverage product. The container includes a cup for holding a liquid, and a percolating mechanism for holding a beverage mix at a predetermined location within the cup, the beverage mix being provided in a solid, granular, gel and/or packaged form. A filter may be coupled to the percolating mechanism for separating the beverage mix from liquid disposable in the cup, and a stem may be coupled to the percolating mechanism for enabling axial movement of the percolating mechanism relative to a longitudinal axis of the cup. The stem may enable mixing of the beverage mix with the liquid and enable removal of the percolating mechanism from the cup upon mixing of the beverage mix with the liquid for thereby providing the mixed beverage product. The invention thus provides an all-in-one beverage container which is easy to use, hygienic and disposable.

  • Publication number: 20080245237
    Abstract: A press assembly is adapted to be used with a disposable stackable cup. According to the preferred embodiment, the press includes a filter. A resilient radially compressible support forms a seal is formed between the filter and the interior of the cup. A detachable rod is mounted to the support. The support is sized to accommodate all radii of the cup. As the user presses down the rod, the press assembly is pushed downward to the bottom of the vessel. The seal maintains continual and firm pressure on the inside surface of the vessel so that the pressurized liquid passes through the filter and the infusion substance is trapped.

  • Patent number: 7337714
    Abstract: An apparatus for pressing coffee has a base and housing supporting a filtercup and a pressing cylinder. The pressing cylinder has a forked end engaging a cylindrical body and attached to a rocker arm. A counterweight is attached to an end of the rocker arm. The cylindrical body has a rack engaging a ring gear activated by a lever. Movement of the lever causes movement of the cylindrical body and pressing cylinder. A pinion attached to the cylindrical body moves along a second rack. Movement of the pinion is translated to a bevel gear pair and a pin between the prongs of the forked end.

  • Patent number: 7279660
    Abstract: An electrically heated water kettle comprises a vessel for holding a liquid for extraction of tea, coffee or other food material. The vessel includes a partially open immersible container sized to allow the passage of water between the walls of the vessel. The container is capable of holding the material while an opening in the container allows the entrance of water into the container upon immersion of the container in the water. The heated kettle incorporates structure to hold the container out of the water until the water reaches an appropriate extraction temperature and to immerse or withdraw the container into or from the water as is necessary to accomplish the extraction.

  • Patent number: 7270050
    Abstract: A brewing apparatus for infusing compacted ground coffee in a grounds cup at a brewing station with heated water under pressure. At a brewing station, a piston head with an active seal that is spaced from the grounds cup wall during motion, extends into the grounds cup. When the piston head begins to compact the ground coffee it activates the seal to form a sealed upper end of a brewing chamber. Hot water is admitted to the brewing chamber to produce the coffee. When the brewing cycle is completed, the piston head displaces further to force additional coffee from the grounds. Then the piston head retracts to allow the infusion chamber assembly to be removed for cleaning.

  • Patent number: 7213507
    Abstract: An infusion beverage brewing system includes a container and an infuser. The infuser is positioned in a liquid, such as hot water, and has an infusing chamber for containing infusible materials, such as tea leaves. A plunger includes a piston with a peripheral seal and flap valves. After a brewing time has elapsed, an individual pushes on an operator to move the piston past a perforated wall portion of the infusing chamber. When the piston reaches a solid wall portion at the bottom of the infusing chamber, the flap valves open to allow liquid to escape. However, small apertures aligned with the flap valves prevent the passage of the infusible material. Consequently the infusible material is isolated from the liquid when the piston reaches a solid bottom wall portion of the infusing chamber.

  • Patent number: 7093531
    Abstract: Device having a cover to be positioned on a vessel with an interior wall. A shaft extends through a transverse passageway in the cover. A basket for holding a flavoring substance is mounted to the end of the shaft. The basket can thus be raised and lowered within the vessel through action of the shaft. A continuous lip of flexible polymer surrounds the periphery of the basket, for engagement with the interior wall of the vessel. With flavoring substance in the basket, liquid is poured into the vessel in such a way as to retain air in the space between the basket and the bottom of the vessel. The basket is pushed downwards, causing at least part of the air retained in the space between the basket and the bottom portion of the vessel to displace the flavoring substance while the air rises within the vessel, resulting in improved infusion of the flavoring substance.
