摘要:
For use in a single serve beverage brewer in which a measured charge of a dry beverage medium is infused with a metered amount of heated liquid to produce a beverage medium, a reusable beverage filter cartridge is provided for containing the beverage medium and for accommodating an inflow of the heated liquid and an outflow of the beverage medium. The cartridge comprises a cup-shaped housing having a top opening and a closed bottom with an outlet port. A filter internally subdivides the housing into a first chamber accessible via the top opening and configured and dimensioned to contain the beverage medium, and a second chamber communicating with the outlet port. A lid is removably secured to the housing in a position closing the top opening, and an inlet port in the lid serves to admit heated liquid into the first chamber for infusion with the beverage medium contained therein. The filter is permeable to accommodate a flow therethrough of the resulting beverage into the second chamber from which it exits via the outlet port.

A method of forming and inserting filter elements into cup-shaped containers comprises the steps of: a) folding a continuous web of filter material into two adjacent plies which have separable upper edges and are joined one to the other along a bottom fold line; b) blanking the adjacent plies to form their upper edges into a scalloped pattern; c) inserting carrier mandrels between the adjacent plies; d) joining the adjacent plies along seams extending transversely with respect to the bottom fold line to form a series of collapsed frustoconical filter elements interconnected by scrap segments and supported internally by the carrier mandrels; e) separating the filter elements one from the other by blanking and removing the scrap segments; f) transferring the filter elements from the carrier mandrels into cup-shaped containers arranged therebeneath; and g) securing the thus inserted filter elements to interior surfaces of the cup-shaped containers.

摘要:
A cup shaped holder is internally provided with an ejection mechanism which serves to automatically dislodge a spent beverage cartridge from an upwardly extending piercing member when the lid is opened at the end of a brewing cycle. In addition, the holder is mounted on externally protruding trunnions for pivotal movement between an upright brewing position and a partially inverted position to eject the dislodged cartridge from the holder into an underlying receptacle. The lid has a dependency arm that coacts with a pawl on the holder trunnions to automatically manipulate the holder to eject the cartridge.
摘要:
An automated beverage brewing system includes a liquid storage tank and a metering chamber. The metering chamber is at least partially submerged beneath a standing level of liquid in the storage tank. The chamber includes a sealable liquid inlet port communicating with the interior of the storage tank beneath the standing level of liquid. The chamber also includes a liquid outlet port and an aperture that receives compressed air, wherein the compressed air forces a predetermined amount of liquid from the liquid output port of the chamber for use in preparing a brewed beverage. A pump provides the compressed air and a controller monitors a pressure signal value indicative of the air pressure in the metering chamber. The controller commands the pump on to commence flow of the predetermined amount of liquid from the metering chamber. The controller then commands the pump off several seconds after detecting a drop in air pressure within the chamber, indicating that the predetermined amount of liquid has been delivered to the brewing chamber. The chamber is then vented to ambient pressure, which opens the sealable liquid inlet port and refills the chamber.
