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 dripper for extracting regular coffee into a cup for use in a simple extraction dripper with an open top and a flat-type bag with two sides combined. This filter (3) The mouth (4) of the bag (5) has a mouth frame separated on the front side and the back side, and each is integrally formed around the mouth of the bag (5). The front frame (16) has a folded portion (6) extending upward at each of the left and right ends, which constitutes a mouth frame which is attached via a bag (5) and integrated. Back frame (13)
Has a pouring surface (8) extending upward, and further below has a set plate (18) extending only to the left and right in a central portion only with the bag (5). A notch (9) for hooking is provided, and furthermore, a folded part (1) extending upward is provided on both left and right ends of the rear frame (13).
4) is provided, and is integrated with the left and right folded portions (6) of the front frame (16) and the filter (3) of the bag (5), so that one folded portion is provided at the position of the left and right side edges (17). This is a simple dripper that has a fold (15) on both sides of the pouring surface (8), which constitutes a part.

[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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a simple coffee dripper for extracting regular coffee, a simple dripper of a bag type with an open upper opening for use in a cup is used. A bag (5) constituted by a filter (3). The mouth (4) of the bag (5) has a mouth frame separated on the front side and the back side, and each has a mouth portion of the bag (5). The front frame (16) has a folded part (6) extending upward at each of the right and left ends, which is integrally attached to the periphery and forms an opening frame which is integrated via a bag (5). Doing, rear frame (13)
Has a pouring surface (8) extending upward, and further below has a set plate (18) extending only to the left and right in a central portion only with the bag (5). A notch (9) for hooking is provided, and furthermore, a folded part (1) extending upward is provided on both left and right ends of the rear frame (13).
4) is provided, and is integrated with the left and right folded portions (6) of the front frame (16) and the filter (3) of the bag (5), so that one folded portion is provided at the position of the left and right side ends (17). This is a simple dripper that has a fold (15) on both sides of the pouring surface (8), which constitutes a part. When the present invention is used, the mouth (4) of the flat two-sided bag (5) is opened, and the left and right folds (15) provided on the pouring surface (8) are bent inward, and the bag (5) is further bent. The folded portion (6) and the folded portion (14) integrated by the filter (3) are provided one at each of the left and right ends (17), and the folded portion extending upward is bent outward. The folds at the left and right side ends (17) of the bag (5) extend linearly in the mouth frame portion, the front frame (16) is curved, and the mouth portion (4) is opened and fixed in a round shape. At this time, the set plate (18) provided below the rear frame (13) is linearly extended right and left since only the central portion is integrated with the bag (5). Put the simple dripper into the cup (10), move it toward the inside of the cup (10), and turn the front frame (16) toward the center of the cup (10) to cut the cut (9) provided on the set plate (18) on both the left and right sides. Insert it into the edge of the cup and set. The coffee powder (7) is put in the bag (5), hot water is further poured into the bag (5) to extract coffee, and then the knob (11) on the back side of the pouring surface (8) is picked up by the cup (10). Remove from hot water and drip. A set mechanism provided at the mouth portion comprising the set plate (18) and the cut (9) also measures the stability of the mouth portion (4) when pouring hot water. In this method, a pouring surface (8) extending upward is provided in order to prevent hot water from spilling out of the cup when pouring hot water, since the hot water is poured toward one side inside the cup and set. The outer surface (12) of the waterproof and heat-insulating surface (2), which is the side wall surface of the bag (5), is gripped by the knob (1).
Since the knob (11) is provided as 1), the user holds the coffee bag by hand and pulls the coffee bag out of the cup (10), so that the hand position is outside the cup (10) or the coffee bag. The heat that rises from inside or inside the coffee bag is not directly received by the hand.
Also, since the knob (11) has the waterproof and 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 rear frame (13) has a tongue (11) at its upper part, which is made of a cardboard-waterproof material to provide rigidity, which is resistant to deformation due to the heat of hot water. This is to make it easier.
