Abstract
The deposit of a suitable coin in a vending machine initiates the delivery of a sealed coffee pack from a revolving magazine, via a chute, to a conveyor table. The pack is advanced by a belt and a sealing sheet removed from the bottom of the pack. The pack is then advanced to a brewing station where a plurality of pointed nozzles are lowered to pierce the pack from above and deliver hot water thereto. The freshly brewed coffee exits the pack through a bottom filter and flows through a funnel into a coffee cup beneath the funnel. The spent pack is then advanced to a disposal chute where it is compacted and dropped into a waste tray.
