ABSTRACT:
A portable package unit used for extraction of coffee including a filter assembly easily attached to a receptacle such as a cup. The package unit includes a filter bag having a predetermined amount of parched coffee powder and a frame internally supporting the filter bag. The frame is made up of a pair of support boards each of which includes a pair of frame sections demarcated by a center fold line and a pair of wing sections connected to associated frame sections via bonding zones. The two support boards are united together along the bonding zones. When folded in a flat state for envelopment in the wrapper, the filter bag is wholly coved by the frame and the wing sections are superposed on the frame sections of the support boards. When unfolded cubically for attachment to the receptacle, the frame sections of the frame separate from each other to define a rectangular solid space in which the filter bag is suspended with its upper end being open for pouring of hot water.
