Abstract: A reusable cartridge and method for forming a beverage using a beverage machine. The cartridge may include a bottom surface with inlet and outlet openings, e.g., arranged to receive an inlet or outlet needle, respectively, and an opening at a top end through which access to the interior space may be had. A filter basket may be inserted or removed into the interior space through the opening and a cover may engage at top to seal the opening closed.

Abstract: Systems and methods for controlling liquid flow to the liquid supply of a beverage forming apparatus. The liquid supply may include two valves positioned in series for controlling a flow of a liquid into the liquid supply. Pressures upstream, between and/or downstream of the valves may be detected and used to determine if one or both of the valves leak when closed.

Abstract: A beverage forming method and system in which a carafe is positionable at a carafe receiving area of a beverage forming machine with a lid of the carafe in an open position or a closed position. The carafe may be positioned at the carafe receiving area in any one of multiple rotational positions within a range of 45 to 180 degrees, and the machine may detect whether the lid is open or not for any of the rotational positions. Beverage forming is prevented if the lid is detected to be closed, allowing the carafe to be safely stored on the machine regardless of lid position.

Abstract: A method and apparatus for dispensing a beverage from a beverage forming machine with reduced gas bubbles or foam. An outlet chamber may be arranged to separate beverage flow into a liquid component and a gas/liquid component such that the liquid component flows downwardly to a first outlet opening and the gas/liquid component flows upwardly and/or through a tortuous path to condition the gas/liquid component and reduce foam prior to the gas/liquid component exiting a second outlet opening.

Abstract: A beverage forming method and system employing the introduction of air into the heater tank and/or an expansion chamber after liquid delivery is complete. An expansion chamber may be provided at the top of the heater tank and provide a tortuous flow path from an air inlet to the tank outlet.

Abstract: A method and apparatus for forming a beverage. Movement of a brew chamber may automatically enable the provision of beverage precursor liquid into a reservoir in a brewer, which is then used (heated or not) to form a beverage. For example, closing of the brew chamber may cause a lid for a water reservoir to be fully opened or otherwise permit movement of the lid to allow access to the reservoir, allowing a user to provide water into the reservoir. The reservoir lid may open with an abrupt action, causing attention to be drawn to the reservoir lid. In another arrangement, closure of the brew chamber may cause actuation of a baffle, pump, valve or other device to provide a suitable amount of water to a reservoir for beverage formation. In another arrangement, opening of the brew chamber may cause the reservoir lid to be automatically and simultaneously opened with the brew chamber.

The valve may open simultaneously and automatically with a brew chamber lid, and may close when the brew chamber lid is closed.

Abstract: A method and apparatus for forming a beverage. A brewer may be operated so that when water or other beverage precursor is detected to be heated to a desired temperature, the liquid may be provided to a brew chamber to form a beverage. In one embodiment, detection of the water temperature may be performed by a temperature cut off switch (TCO) which is normally closed to provide power to a water heater, but opens when the water reaches a predetermined temperature. Opening of the TCO may cause delivery of the liquid to the brew chamber, e.g., by causing pressurization of a reservoir containing the liquid. In another embodiment, control of delivery of water from the reservoir may be made based on power interruption to the heater. For example, an air pump may be controlled to deliver air to the reservoir in response to power to the heater being cut off.

Abstract: A method and apparatus for forming a beverage. An access opening for a reservoir of a brewer may be opened (e.g., to allow a user to provide liquid into the reservoir for forming a beverage), and thereafter, the access opening of the reservoir may be closed and the reservoir pneumatically sealed. The access opening may be closed and the reservoir pneumatically sealed by closing a lid of the reservoir, e.g., by a user pressing down on the lid. Pneumatic sealing of the reservoir may allow the water in the reservoir to be expelled from the reservoir for flow to the brew chamber by introducing air pressure into the reservoir, e.g., by an air pump. The reservoir may be vented during heating of the water, and during pressurization of the reservoir for delivery of the brew water.

Abstract: A method, system and cartridge for forming a beverage includes a cartridge having a container defining an interior space, a lid, a filter, and a beverage medium contained in the interior space. The filter may be attached to the lid only, and extend into the interior space to separate first and second chambers of the cartridge. The filter may hold the beverage medium and be arranged so that, when the lid is removed from the container, e.g., by peeling the lid from the container, the filter and beverage medium are removed together with the lid.

Abstract: A cartridge for forming a beverage includes a container defining an interior space, a filter, a beverage medium contained in the interior space, and a filter guard. The filter may be arranged so that liquid that interacts with the beverage medium flows through the filter to exit the interior space. The container may include a surface arranged to be pierced by a piercing member to permit beverage to exit the container. The filter guard may be arranged to contact the piercing member to resist damage to the filter when the container surface is pierced. In one embodiment, the filter guard and filter may be in contact with the container surface that is pierced, yet damage to the filter that might be caused by the piercing element may be avoided.

Abstract: A beverage forming apparatus includes a storage tank, and a centrifugal pump having an inlet connected to the storage tank by a supply conduit. The centrifugal pump may include a priming vent located below a full level of the storage tank and permit air to vent as liquid primes the pump. A metering tank may have an inlet connected to the centrifugal pump by a pump conduit, and an outlet connected to a brew chamber that forms a beverage using liquid received from the metering tank. In one embodiment, a flow control valve, such as a check valve, may be provided in the pump conduit to allow flow from the pump to the metering tank, but resist flow in reverse. In another embodiment, a vent valve in the pump conduit may be arranged to vent at least a portion of the pump conduit, e.g., to ambient air pressure.
