[0002]

2. Description of the Related Art Conventionally, there have been a drip type placed on the mouth of a cup and a bag type used in a cup.

[0003]

The conventional type placed on the mouth of a cup has drawbacks in terms of the number of operations and the complicated structure. In the case of a sealed bag type used in a cup, it is inserted into the bag through a filter surface. There is a drawback that the extraction requires a long time because hot water flows in and out and a sufficient extraction cannot be obtained. In the method of pouring hot water directly into the bag from the mouth of a bag-type filter bag used in a cup, the filter softens and deforms depending on the temperature and weight of the hot water when the hot water is poured, and the mouth shape of the bag-type filter However, there is a disadvantage that the bag is deformed and closed, so that hot water cannot be poured, or that the entire bag is deformed in the cup and hot water cannot enter. Also, if the bag is placed under the bag and placed against the inside of the cup opening, the upper part of the bag is located outside the cup, so hot water will seep out of the outside wall of the bag. Has occurred.
In addition, if the filter bag is directly held by hand after extraction, it has a drawback that it is hot and the hand is dirty with coffee liquid and is hard to hold.

[0005]

Embodiments of the present invention will be described below. The present invention is a bag-type coffee bag in which one side of a side wall is made of a waterproof heat-insulating material, and coffee liquid extracted from coffee powder in the bag by hot water poured into the bag passes through the filter and is extracted outside the bag. , Is 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 consists of a bag-type filter that has the strength necessary to support the weight of hot water and retain the overall shape and mouth shape of the bag, with one side of the bag covered with a frame plate to add rigidity to the bag. A bag-shaped hand in a cup when filling or using coffee powder in the bag due to its unitary structure that does not have any In the case of forming, extracting, and taking out from the cup, the upper portion of the bag side wall surface is grasped by hand, and the mouth portion is closed to make it easier to grasp. The outer surface (12) of the waterproof and heat-insulating surface (2) on the side of the upper opening (4) serves as a knob (11) for removing the bag (5) from the inside of the cup (10). No additional structure is provided.
The inner surface (1) of the knob (11) also functions as a pouring surface (8) for pouring hot water into the bag, and the knob (11) is manually gripped from the cup (10) to the dripper bag. The function of the heat-insulating plate that protects the hand by shutting off the heat of the steam rising from the inside of the cup (10) or the bag itself when taking out the waterproof heat-insulating surface (2) is added.
Due to its own rigidity, it also has the function of retaining the mouth shape of the upper mouth (4). The waterproof heat-insulating surface (2) may be 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. This is a coffee bag of a type that is set as a set, and the whole is in the form of a flat bag having two surfaces joined together. This is a bag (5) composed of a filter (3). A card board (6) having waterproof and heat-proof properties is integrally attached and provided, and the inner surface (1) on the card board (6) side of the bag (5) covered is used as a pouring surface (8). The card plate (6) constituted by the waterproof and heat-insulating surface (2) having the outer surface (12) as a knob (11) is a filter (3) and a bag (5).
The coffee bag (9) is filled in the bag, which also has rigidity to generate a frame function for retaining the shape of the bag and the shape of the mouth of the upper mouth (4). This is a bag-shaped card coffee that is closed flat and temporarily sealed. When one side is a card plate (6), the lower part of the bag of the bag-shaped filter (3) is hardly bulged due to the flat rigidity of the card plate (6). When a card board is attached while leaving a little, the lower part of the bag (5) is easily swelled, and a space for collecting coffee powder is secured.
The card board (6) is provided with a plurality of longitudinal folds (16). This makes it easy to bend the card plate (6) so that the upper opening (4) can be easily formed in a round shape. A bent portion (15) of the card plate (6) extends upward from the upper opening (4). This bent part (1
In 5), the temporarily sealed upper opening (4) is folded back and fixed to the bag (5) side so that the temporarily sealed upper opening (4) is closed and reinforced to prevent the temporarily sealed upper opening (4) from opening during transportation. The bent portion (15) located above the card plate (6) has an uneven portion (13). This is because the bent part (15) is also the knob part (11) at the same time, which prevents slipping when holding the coffee bag by hand, reduces the contact area between the hand and the card board (6), and adds space to the surface by adding unevenness. The heat insulation effect by the structure is also produced. 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
After the hot water is poured into the bag and extracted, the outer surface (12), which is the side wall surface of the bag (5), which is the knob portion (11), is gradually lifted by hand to gradually raise the knob bag (5) to use the hot water. The bag (5) of the present invention has the lower part fixed to the bottom in the cup (10) and the upper upper port (4) side is tilted in one direction inside the mouth of the cup (10). The flat bag (5) in the cup (10) is stabilized in the front, rear, left and right directions by approaching to the mouth. The bag (5) is in the form of a card having a square shape based on a flat bag shape having two sides and a left side edge (7) and a lower side edge (7). It is a whole shape that is easy to match with filling and storing of coffee. The bottom of the bag (5) is fixed at the bottom in the cup (10), and the weight of the hot water in the bag (5) is basically supported by the bottom in the cup (10). Since the outer surface (12) of the waterproof heat-insulating surface (2), which is the side wall surface of the bag (5), is provided as a knob (11), the knob (11) is picked up from the outside, and the coffee bag is held by hand.
0) Since the hand is positioned outside the cup (10) or the bag when taken out from the inside, the hand does not directly receive the heat rising from inside the cup (10) or the bag. Since the knob (11) has a waterproof and heat-insulating surface (2) itself which is waterproof, when hot water is poured into the pouring surface (8) located on the outside of the cup (10) during extraction, the cup is removed from the outer surface (12). (1
0) Prevents hot water from leaking outside.

[0006]

According to the dripper bag of the present invention, the hot water is poured directly into the bag, so that the extraction speed is high. Also, since the upper side of the bag (5) has rigidity, the upper port (4) is used when pouring hot water. (2) The opening shape is stable and the structure is compact and simple, which does not require a setting mechanism or a frame portion that greatly extends outside the bag. In addition, the card board (6) has a strength for retaining the mouth shape and the whole shape when pouring hot water in the cup (10), and the bag itself and the upper mouth (4) are waterproof and heat-proof surfaces (2).
In addition, the waterproof and heat-insulating surface (2) provided on the bag (5) protects the hand from the rising heat in the cup (10) or the bag, and holds the bag directly with the handle having the knob (11). Hands are not hot and protect from coffee liquid. Knob part (11)
Is provided on the side wall surface, so that the mouth portion is also flatly closed in one stroke in which the knob (11) is held between the outside and the right and left hands.
