Embodiments of the present invention will be described below. The present invention is a bag-type coffee bag in which a part of a side wall, a mouth portion, and the periphery thereof are formed of a waterproof and heat-insulating material, has a filter portion below the bag portion, and has hot water poured into the bag. The coffee liquid extracted from the coffee powder in the bag passes through this filter and is extracted outside the bag and filtered. Further, in order to prevent deformation of the bag shape itself and the mouth shape due to the weight when hot water is poured into the bag (5) in the cup (10), the strength of the bag shape holding is poured in the cup in the present invention. It is made up of a filter that has the strength necessary to support the weight of hot water and retains the overall shape of the bag, and has added rigidity to the bag itself. Because the bag can be configured and arranged, softness also occurs in the entire bag, and when filling or using coffee powder in the bag, forming the bag by hand, extracting and using it, or removing it from the cup In addition, the upper portion of the side wall of the bag is grasped by hand, and the mouth portion is easily closed and grasped. The outer surface (12) of the waterproof heat-insulating surface (2) constituting the upper opening (4) serves as a knob (11) for taking out the bag (5) from inside the cup (10), and in particular, the knob is used as the bag (5).
Has no additional structure. In addition, this knob (1
The inner surface (1) of (1) also functions as a pouring surface (8) when pouring hot water into the bag, and the knob (11) is gripped by hand to take out the dripper bag from the cup (10). (10) The waterproof heat-insulating plate (2) acts on the heat-insulating plate that protects the hands by shutting off the heat of the steam rising from the inside or the bag itself, and the upper opening (4) due to the rigidity of the waterproof heat-insulating surface (2) itself. ) To maintain the shape of the mouth. The waterproof heat-insulating surface (2) is made of synthetic resin or waterproof paper.
Therefore, the present invention is as follows. 1. This is a bag type coffee bag with an upper opening that is used in a simple coffee extraction bag. The bottom of the bag is fixed to the bottom of the cup and the top of the bag is leaned on the inside of the cup opening. The bag (5) is a filter (3), and the bag (5) is a filter bag.
The upper opening (4) has a slant-cut opening, one of which is extended upward. The inner surface (1) is a pouring surface (8), and the outer surface (12) is a knob (11). The upper port (4) is made up of a waterproof and heat-insulating surface (2) having waterproof and heat-insulating properties. A bag (5) is composed of the waterproof and heat-insulating surface (2) and the filter (3), and the bag is filled with coffee powder (9) and the upper opening (4) is temporarily sealed. It is. When the present invention is used, the temporarily sealed upper mouth (4) is opened to form a round mouth shape, and the bag shape is formed three-dimensionally to increase the capacity of the flat bag to increase the capacity of the bag (5). Put the bag in the cup (10) and set it. Pour hot water into the bag and extract it after the knob (1
