[0003]

The conventional type that is placed on the mouth of a cup has drawbacks in terms of the number of uses and a complicated structure, and the full pack type that is used by putting it in the cup uses hot water inside the pack through the filter surface. However, there is a problem that it takes time to extract and sufficient extraction cannot be obtained, and it is a bag-type filter pack that is used by putting it in a cup and pouring hot water directly into the pack from its mouth The filter softens and deforms depending on the temperature and weight of the hot water when pouring, and the mouth shape of the bag type filter deforms and closes, making it impossible to pour hot water or the entire bag deforms in the cup and the hot water cannot enter. If you put the lower part of the bag inside the cup and lean it toward the inside of the cup mouth, part of the upper part of the bag is located outside the cup, so hot water flows from the wall surface of the bag to the outside of the cup. Exudation has occurred or, also hand there was also difficult to have dirty drawback in the hot, also coffee solution with a direct hand click Tsu this filter path after the extraction.

[0004]

Therefore, the present invention has the following features. 1. In the simple coffee extraction device, the front side is a flat filter (11) and the back side is a waterproof / heat insulating plate (2). These two surfaces are brought into close contact with each other at the left and right side ends (14) and the lower end (15), and the upper mouth is opened. After the bag-shaped container (1) is extracted, the outer surface (3) of the waterproof and heat-insulating plate (2) that constitutes the entire back side wall of this bag forming the flat bag-shaped container (1) having (4) is The inner surface (1) of the waterproof / heat insulating plate (2) is provided at the upper opening (4) which is a knob portion (5) for taking out the knob manually.
The flat filter (11) having 0) as the hot water pouring surface (6) is a hard filter, and the waterproof and heat insulating plate (2) on the back side is also hard. 9) The coffee powder (1) inside the bag-shaped container (1) has strength to prevent deformation of the bag-shaped or mouth-shaped due to the weight of the hot water when pouring hot water into the bag-shaped container (1). Card coffee obtained by filling 7) and temporarily sealing and sealing the upper opening (4) at the temporary sealing portion (8).

[0005]

[Operation] When the present invention is used, the mouth portion of the upper mouth (4) that is temporarily adhered is opened to form a mouth shape or a bag shape three-dimensionally by hand to increase the inner volume of the bag ( Put the whole lower part of the pack of 1) into the cup (9), pour hot water into the bag, and after extraction, the outer surface (3) which is the side wall surface on the back side of the bag type container (1) which is the knob part (5). Gradually lift the bag-shaped container (1) by hand to drain water.

[0006]

[Embodiment] The present invention is based on a bag-type filter, and the back side of the wall surface of the bag-type container is provided with a waterproof surface for preventing leakage of hot water to the outside of the cup, a knob portion, and a heat insulating plate function for its heat insulating effect. A flat bag-type container having a waterproof and heat insulating plate (2) as a flat plate mainly integrated into one surface, and mating each other with a flat filter (11) and the front side serving as a filter part Provided bag type container (1)
It is what Also, the bag-shaped container (1) in the cup (9)
When the strength of the bag shape holding due to the hardness to prevent deformation of the bag shape and mouth shape due to the weight of hot water when pouring hot water into the inside is given to only one side of the back side, the hardness is generated on only one side It is difficult to fill coffee powder inside the bag, it is difficult to form a bag shape during extraction use, and if only the filter surface side is soft, the bag shape on the filter surface side will deform when hot water is poured In the present invention therefor, the entire bag shape supports the weight of the hot water poured into the bag in the cup, and the strength due to the hardness required to maintain the entire shape and mouth shape of the bag provides the front surface of the bag itself. And the whole back and back. As a result, the hardness is dispersed to form a softness in the entire bag shape, resulting in the filling of the coffee powder in the bag, the formation of the bag shape in the cup, and the extraction use and the removal from the cup. The back side can be easily gripped by closing the mouth with the hand. When the hardness on the side of the flat filter (11) is slightly softened from the side of the waterproof / heat insulating plate (2), the action and usability can be improved. In addition, since the coffee pack is an extraction targeting one cup, if the entire bag part is used as a filter, the filter area will be large and the extraction speed will be too fast. In this case, it is necessary to reduce the area of the filter. Therefore, only one side of the bag shape is used as the filter, and the filter area is reduced while securing the required bag volume. The waterproof / heat insulating plate (2) which is a flat plate serves as a knob portion (5) when the outer surface (3) is taken out from the cup (9), and the knob portion is not structurally provided in the bag-shaped container. The inner surface (10) of the knob portion (5) also functions as a pouring surface (6) when pouring hot water into the bag, and the knob portion (5) is manually gripped from the cup (9) to the dripper pack. The water-proof and heat-insulating plate (2), which is entirely flat, acts as a heat-insulating plate that shields the heat of steam rising from the inside of the cup (9) and the pack itself when taking out the product to protect the hand. As the waterproof / heatproof plate (2) which is a flat plate, synthetic resin or waterproof cardboard is used. Therefore, the present invention has the following features. 1. In the simple coffee extraction device, the front side is a flat filter (11) and the back side is a waterproof / heat insulating plate (2). These two surfaces are brought into close contact with each other at the left and right side ends (14) and the lower end (15), and the upper mouth is opened. After the bag-shaped container (1) is extracted, the outer surface (3) of the waterproof and heat-insulating plate (2) that constitutes the entire back side wall of this bag forming the flat bag-shaped container (1) having (4) is The inner surface (1) of the waterproof / heat insulating plate (2) is provided at the upper opening (4) which is a knob portion (5) for taking out the knob manually.
The flat filter (11) having 0) as the hot water pouring surface (6) is a hard filter, and the waterproof and heat insulating plate (2) on the back side is also hard. 9) The coffee powder (1) inside the bag-shaped container (1) has strength to prevent deformation of the bag-shaped or mouth-shaped due to the weight of the hot water when pouring hot water into the bag-shaped container (1). Card coffee obtained by filling 7) and temporarily sealing and sealing the upper opening (4) at the temporary sealing portion (8). The present invention is a bag type container (1) of a single-sided filter (1) in which one side is a filter and the other side is a flat plate, and two sides are combined, and the front side is a flat filter (1).
1) and the entire back surface is made of a waterproof and heat insulating plate (2) to open the upper mouth (4), and even if the mouth shape is circularly formed by hand, the flat filter (11) is below the bag-shaped container (1). Since the two surfaces of the waterproof and heat insulating plate (2) maintain a flat shape by the action of hardness, the bag-shaped container (1) has a smaller cross-sectional area from the horizontal direction in the lower part and a smaller volume in the lower part ( The whole shape of 1) becomes an inverted conical shape. Therefore, when hot water is poured into the bag-shaped container (1) in the cup (9), the volume below the bag-shaped container (1) is larger than that in the cup (9) in hot water in the cup. Has a small occupancy rate, which has the effect of increasing the drip rate. The bag-shaped container (1) of the present invention has its lower part placed on the bottom of the cup (9), and the upper mouth (4) side is tilted in one direction inside the mouth part of the cup (9) to close the waterproof and heat insulating plate (2) side. The flat bag-shaped container (1) in the cup (9) is stabilized in the front, rear, left, and right directions by bringing it toward the mouth of the cup (9) in a state in which it is in the outward direction. The bag-shaped container (1) is in the shape of a card that has a square shape based on a flat bag shape with two sides combined, and has an easy-to-manufacture shape that matches the machine for filling coffee. It is a shape. The lower part of the bag-shaped container (1) is placed at the bottom of the cup (9), and the weight of hot water in the bag-shaped container (1) is basically supported by the bottom of the cup (9). is there. Since the outer surface (3) of the waterproof and heat insulating plate (2), which is the side wall surface on the back side of the bag-shaped container (1), is provided as the knob portion (5), the knob portion (5) is grasped from the outside and the coffee pack is manually grasped. Since the position of the hand is outside the cup (9) and the pack when taking out from the holding cup (9), the heat rising from the cup (9) and the inside of the pack is not directly received by the hand and the coffee pack is directly exposed. You can hold the knob by hand. Also, the knob part (5) is a waterproof and heat insulating plate (2).
Since it is waterproof itself, it prevents the hot water from leaking from the outer surface (3) to the outside of the cup (9) when pouring hot water onto the pouring surface (6) located on the outside of the cup (9). Further, the knob portion (5) provided on the outer surface (3) of the back side wall of the bag-shaped container (1) is protected from the coffee liquid by the waterproof and heat insulating plate (2) having the waterproof property. . According to the present invention, a waterproof surface is provided on a flat surface on the back surface side of the bag portion to form the knob portion. By enlarging the waterproof surface, steam is generated from the periphery of the knob portion to the hand side due to the waterproof action. It is a knob portion that has a large waterproof and heat-insulating surface to prevent heat generation and rise to the hand side that has a knob portion. As shown in FIG. 4 and FIG. 5, instead of the flat filter (11), a bag-shaped filter (1
3) is provided, and on the back side of the side wall surface, a waterproof and heat insulating plate (12) is provided which has a width extending toward the left and right ends of the upper opening (4) and further extends downward to form a flat shape. The bag-shaped dripper pack may be a bag-shaped dripper pack in which the back surface of the bag-shaped filter (13) is largely covered on the back surface side and integrally attached to the outer surface.

[0007]

Since the dripper pack of the present invention pours hot water directly into the pack, the extraction is fast and the front and back sides of the bag-shaped container (1) have hardness, so that when the hot water is poured upward The mouth shape of the mouth (4) is opened stably, and a compact and simple structure that does not require a setting mechanism or the like that greatly extends outside the bag-shaped container (1) is provided. Further, the strength of holding the mouth shape and the whole shape when pouring hot water in the cup (9) is also generated by the hardness of the entire bag portion, and the knob portion (5) is held from the outside by the hand holding the pack ( 9) Due to the heat inside or inside the pack, the waterproof and heat insulating plate (2) serves as a heat insulating plate, and the hands directly holding the pack also protect from the coffee liquid. Knob part (5)
Since the side wall surface is provided with, the mouth portion can be closed flat in one stroke by pinching the knob portion (5) from the left and right sides by hand. Since it is a flat bag type pack, the capacity of the bag is small and the hot water in the cup is easily drained, so that the drip action can be obtained even in the cup (9). Coffee powder (7) accumulates downwards and the hot water runs out quickly.
