る即席コーヒー煎れ器。 A coffee powder pack is prepared by putting coffee powder into a bulge-shaped container with tapered sides formed of a rigid non-woven fabric or filter paper, and sealing the coffee powder by overlaying a sheet-like non-woven fabric or filter paper, and a peripheral seal part of this coffee powder pack. A pouring cylinder consisting of a suspended stepped part and a housing chamber for an expansion/injection part, and a presser cylinder that clamps and presses the peripheral seal part of the coffee powder pack against the stepped part of the pouring cylinder, A groove is formed in the stepped part of the pouring cylinder to clamp and press the peripheral seal part of the coffee powder pack at the lower opening edge of the presser cylinder, and the storage chamber in which the coffee powder pack's expanded accommodating part is accommodated is located inside the groove. The wall is formed into a bulge having an inner diameter slightly smaller than the outer diameter at the center of the side surface of the coffee powder pack, and a protrusion that supports the bottom surface of the coffee powder pack is formed in the center of the lower bottom having a plurality of through holes. is formed on the inner surface of the pouring barrel and the outer surface of the presser tube, so that when these two are stacked and rotated, the peripheral seal of the coffee powder pack is connected to the groove in the step of the pouring tube and the presser tube. This instant coffee brewer is provided with engaging protrusions that are clamped and fixed with the lower end surface of the cylinder.
