Abstract
Abstract A powdered drink brewing bag comprising a filter paper bag body having gusset walls and containing a powdered material, such as coffee powder therein. A frame type support member formed of thick paper is bonded to opposing walls of the bag body in the vicinity of the upper edge thereof in such a manner that the bag body is held at both surfaces thereof between the opposite surfaces of the support member. Arm portions project outwardly from the portions of the support member which correspond to both sides of the filter paper bag body, and are provided with folds and handles so that the arm portions are bent in the shape of the letter "Y" in plan to enable the gusset walls to be expanded. Accordingly, the upper edge portion of the bag body can be maintained in a largely opened state, so that the hot water can be poured thereinto easily. This enables the brewing bag to be used easily, and a drink, such as coffee to be obtained conveniently.
