| 20120058226 | BEVERAGE CARTRIDGE - 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. | 03-08-2012 |
| 20110200726 | METHOD AND APPARATUS FOR BEVERAGE FORMATION WITH AUTOMATED WATER DELIVERY TO HEATING TANK - A method and apparatus for forming a beverage using a beverage formation device. Opening of a brew chamber may automatically enable the provision of beverage precursor liquid from a reservoir to a heating tank that is used (heated or not) to form a beverage. For example, opening of the brew chamber may cause a valve to be opened or otherwise permit flow of beverage precursor liquid from the reservoir to the heating tank. The valve may open simultaneously and automatically with a brew chamber lid, and may close when the brew chamber lid is closed. | 08-18-2011 |
| 20100303964 | CARTRIDGE WITH FILTER GUARD - 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. | 12-02-2010 |
| 20100024658 | BEVERAGE FORMING APPARATUS WITH CENTRIFUGAL PUMP - 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. | 02-04-2010 |
