Abstract: A beverage making machine may be arranged to cool a precursor liquid in a tank using a cooling liquid in a cooling container disposed around the tank. The cooling liquid may be freezable to form ice, e.g., to provide the system with improved cooling capacity and/or speed. A plurality of fins may extend between the tank and the cooling container, with each of the plurality of fins being physically attached to the cooling container or the tank and being arranged to conduct heat from the tank and/or from the cooling liquid. The plurality of fins may include first portions attached to the tank and extending outwardly, and second portions attached to the cooling container and extending inwardly. Side surfaces of corresponding first and second portions may be in contact with each other to aid in transferring heat via the fin portions.

Abstract: Method and apparatus for forming both carafe quantities and smaller (e.g., cup) quantities of a beverage using a cartridge-based beverage machine. A beverage forming machine accommodates cartridges having different sizes and/or shapes, including different rim sizes/shapes. The outlet used for receiving a beverage from a standard cartridge differs from the outlet used for receiving the beverage from a carafe cartridge inserted in a same cartridge holder. Beverage may exit the cartridge in an upward direction in some embodiments.

Abstract: Systems, methods and cartridges for carbonating or otherwise dissolving gas in a precursor liquid, such as water, to form a beverage are disclosed. A gas source, which is used to generate gas that is dissolved into the precursor liquid, and/or a beverage medium, such as a powdered drink mix or liquid syrup, may be provided in a cartridge. The use of one or more cartridges for the gas source and/or beverage medium may make for an easy to use and mess-free system for making sparkling beverages, e.g., in the consumer's home.

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: 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: Apparatus and method for forming beverages using a beverage cartridge and sonic energy. A cartridge may include a sonic receiver, such as a feature that extends into an interior space of the cartridge and is arranged to receive a sonic emitter that introduces sonic energy into the interior space. The sonic receiver may be excited by sonic energy, which causes the sonic receiver to itself introduce sonic energy into the cartridge.

Abstract: A beverage forming method and system in which a carafe with an associated magnetic element is positionable at a carafe receiving area. One of a protrusion and a first recess is associated with the carafe and the other of the protrusion and the first recess is associated with a housing. The housing includes a detector arranged to detect the presence of the magnetic element when the protrusion is inserted into the first recess. Beverage formation of an amount greater than a threshold volume is enabled when the detector detects the magnetic element.

Abstract: A method and apparatus for opening and closing a cartridge holder of a beverage forming machine. The cartridge holder may have an opening arranged to receive and hold a cartridge with the cartridge holder. The opening may be adjustable in size and/or shape to allow the cartridge holder to receive and engage with cartridges of different size and/or shape. The cartridge holder may include one or more movable portions that are adjustable in position to effectively adjust a size and/or shape of the opening.

Abstract: A method and apparatus for controlling operation of a beverage forming machine arranged for use with cartridges of different types, or receiving an upwardly flowing beverage from a cartridge. A beverage outlet may be movable to receive beverage from a cartridge of a first type, and to not receive beverage from a cartridge of a second type. Different cartridge characteristics may be detected by multiple detectors, e.g., for detecting a presence/absence of a cartridge, a cartridge type and/or an authorization feature.

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.
