IPC: A47J31/46
Filed: 2020-08-13
Abstract: The present invention relates to a coffee capsule capable of quickly and uniformly extracting ice coffee by raising water from bottom to top in a plurality of chambers filled with ground coffee. The coffee capsule of the present invention includes at least one chamber (the cross section of the chamber is one to 20 times smaller than the whole cross section of a capsule) dividing the capsule into a plurality of parts, and filled with ground coffee. As water is raised from bottom to top in the chamber (if the water is supplied from top to bottom, the coffee powder in the capsule cannot be evenly invaded because a route for the water to flow down is fixed (a waterway is created) due to the gravitational influence), the coffee can be uniformly instilled into the chamber. Therefore, coffee can be extracted with cold water even for a short time, and a high concentration and taste uniformity can be secured.
