DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple extraction dripper for regular coffee.

[0002]

2. Description of the Related Art Conventionally, there have been a drip type placed on the mouth of a cup and a thread hanging sealed 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 thread-hanging sealed bag type used in a cup, the bag is passed through a filter surface. There is a drawback that the extraction takes a long time because hot water flows in and out, and sufficient extraction cannot be obtained. Also, in the method of pouring hot water directly into the bag from the mouth of the bag-type filter used in the cup, the filter softens and deforms depending on the temperature and weight of the hot water when the hot water is poured, causing the shape of the mouth of the bag-type filter to change. It has the disadvantage that it is deformed and closed, making it impossible to pour hot water or that the whole 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 bag filter is directly held by hand after extraction, it has a drawback that it is hot and the hand is dirty with a coffee liquid and is difficult to hold.

[0004]

According to the present invention, there is provided the following. A simple extraction dripper for regular coffee is a bag-type simple dripper with an open upper opening for use in a cup. The bottom of the bag is fixed to the bottom of the cup, and the top of the bag is leaned inside the cup opening. This is a simple dripper of a set type. The whole is in the form of a flat bag with two surfaces combined, and this is a bag (5) composed of a filter (3). A card board (6) constituted by the surface (2) is integrally attached and provided and covered. The inner surface (1) is a pouring surface (8), and the outer surface (12) is a knob (11). The knob (11) of the card plate (6) is the upper opening (4)
It extends further upwards and is rigid for forming the mouth of the upper mouth (4) and also has a fold (14) in the vertical direction. The lower part is used as a face frame (13) for supporting the bag (5). And extends downward from the upper opening (4) to form a card plate (6). The periphery of the upper opening (4) is formed by a front opening frame (15) and a card plate (6). The mouth frame is provided with folded portions (16) extending upward from side ends (7) located on the left and right sides, respectively.

[0005]

Embodiments of the present invention will be described below. The present invention is a bag-type simple extraction dripper provided with a surface frame formed of a waterproof and heat-insulating material on one side of a side wall, and the coffee liquid extracted from coffee powder in the bag by hot water poured into the bag. The system is extracted and filtered outside the bag through a bag filter. 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 maintain the overall shape and mouth shape of the bag with respect to the weight of hot water, and has one side of the bag covered and reinforced with a surface frame to add rigidity to the bag. In particular, it has a single unit structure without a frame part, which allows the rigidity to be configured and arranged in the necessary part of the bag, so that the bag itself becomes soft, so that the bag is filled with coffee powder and used in the cup at the time of use The upper portion of the side wall of the bag is also grasped by hand when the bag is formed and extracted by hand or taken out of the cup by hand, so that the mouth portion is closed and pinched. 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) when hot water is poured into the bag, and the knob (11) is manually gripped from the cup (10) to form the bag. The water-proof heat-insulating surface (2) is used to protect the hand by blocking the heat of the steam rising from the cup (10) and from the dripper when removing the simple extraction dripper. The hardness of the upper mouth (4) also serves to maintain the shape of the mouth. The waterproof heat-insulating surface (2) may be made of synthetic resin or waterproof cardboard. Therefore, the present invention is as follows.

Embodiment 1 In a simple coffee dripper for extracting regular coffee, this is a simple dripper of a bag type having an open upper opening which is used in a cup in a cup. The bottom of the bag portion is fixed to the bottom of the cup, and the upper portion of the bag is a cup opening. A simple dripper that leans on the inside of the part to form a set. The whole is in the form of a flat bag with two surfaces combined, and this is a bag (5) composed of a filter (3). On one side, a card plate (6) constituted by a waterproof and heat-insulating surface (2) is integrally mounted and covered. The inner surface (1) is a pouring surface (8), and the outer surface (12) is a grip portion. The knob portion (11) of the card plate (6), which is (11), extends upward from the upper opening (4) and has a rigidity for forming the opening of the upper opening (4), and has a fold in the vertical direction. (14) also has
The lower part is for supporting the bag (5) as a face frame (13) and extends below the upper opening (4) to constitute a card board (6). The periphery of the upper opening (4) is A mouth frame is constituted by the front side mouth frame (15) and the card plate (6). The mouth frame further includes folded portions (16) extending upward from side ends (7) located on the left and right sides, respectively. This is a bag-type coffee bag in which coffee powder (9) is filled in the bag (5), the upper opening (4) is closed flat and temporarily sealed.

[Embodiment 2] The same effect can be obtained by forming the bag (5) with a filter (3) having rigidity instead of the face frame (13) of the card board (6).

Embodiment 3 The required rigidity of the bag (5) may be secured by matching the hardness of the surface frame (13) and the body of the bag (5). When the entire surface of one side is a card plate (6), the lower part of the bag (5) of the bag-shaped filter (3) becomes round and hard to swell due to the flat hardness of the card plate (6), as shown in FIG. Leave the bag lower part (17) large on the face frame (1
When 3) is attached, the whole or lower part of the bag (5) is easily swelled, and a large space for storing coffee powder is secured.
When using the present invention, the upper opening (4) is opened, the fold (14) provided on the knob (11) side of the card board (6) is bent inward, and the upper opening (4) is greatly opened. The folded portion (16) provided in (7) is bent outward by hand. At this time, since the left and right side ends (7) are linear, the front mouth frame (15) is curved and the knob portion (11) is formed. The upper mouth (4) opens in a circular shape as a whole and becomes stable even when the hand is released. In addition, the bag shape is formed three-dimensionally, the capacity of the flat type bag is increased, and the bag (5) is placed in the cup (10) and set. Then, hot water is poured into the bag and the knob (11) is extracted. The outer surface (12), which is the side wall surface of the bag (5), is picked up by hand, and the bag (5) is gradually lifted and used for draining. 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. Bag (5) is 2 whole
The card is shaped like a square with a flat bag shape with the left and right side edges (7) and the lower side edge (7). It matches coffee filling and storage. The overall shape is easy to do. 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. Since the position of the hand is taken out of the cup (10) or the coffee bag when taken out from the inside, the heat that rises from the inside of the cup (10) or the inside of the coffee bag is not directly received by the hand. Further, since the knob (11) has the waterproof heat-insulating surface (2) itself waterproof, when hot water is poured into the pouring surface (8) located outside the cup (10) during extraction, the cup ( 10) Prevents hot water from leaking outside. The card board (6) has a grip portion (11) at its upper part, which is made of a cardboard-waterproofed material or the like to provide hardness, which is resistant to deformation due to the heat of hot water. This is to make it easier.

[0006]

The coffee bag of the present invention can be quickly extracted because hot water is poured directly into the bag, and has a rigid upper portion of the bag (5). )
The opening of the opening is stable and it is a compact and simple structure that does not require a setting mechanism or a frame that greatly extends outside the bag. The card board (6), which is a waterproof heat-insulating surface (2) provided on the bag itself and the upper mouth (4), retains the shape of the mouth and the whole shape when hot water is poured in the cup (10).
In addition, the waterproof 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 hand with the knob (11) directly. The hand to hold is not hot and also protects from coffee liquid. Knob part (1
Since 1) is provided on the side wall surface, the mouth portion is also closed flat in one stroke in which the knob portion (11) is held between the outside and the left and right by hand.
