Abstract

A coffee maker for use in a vehicle such as a commercial aircraft. The coffee make accepts a sealed can of ground coffee. The can is pierced from the side by a pair of can-piercing spikes by actuating the can against the spikes. The can is drawn by a hydraulically operated cylinder mechanism powered by the water pressure of the aircraft'"'"'s potable water supply. Hot water is injected into the can through a passage within at least one of the spikes and the hot water is circulated within the can thereby brewing the coffee. Brewed coffee exits the can along the sides of one or both of the spikes and is channeled down into a reservoir located below the can. The brewed coffee may be filtered before and/or after the flowing into the reservoir. A desired volume of coffee may then be drawn from the reservoir.

directing the brewed coffee out of the can past at least one of the spikes and then into a reservoir;

wherein the step of piercing the can comprises piercing a side of the can with the first and second spikes, and wherein the step of injecting hot water comprises injecting the hot water into a longitudinal passage within the first spike and then horizontally out through an opening in a side wall of the first spike.

10. A method for making coffee comprising the steps of

inserting a can containing ground coffee into a coffee maker;

automatically piercing the can with a spike;

injecting hot water into the can via an opening within the spike;

making brewed coffee by circulating the hot water within the can;

directing the brewed coffee out of the can along outer periphery of the spike and into a reservoir.

11. A method according to claim 10 wherein the step of piercing the can comprises moving the can horizontally into the spike.

12. A method according to claim 10 further comprising

moving the can into the spike via a hydraulic actuator and

actuating the hydraulic actuator via water pressure from a water supply.

13. A method according to claim 10 further comprising inserting the can into the coffee maker in an upright position and piercing a side of the can with the spike.

14. A method according to claim 10 further comprising
