Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, there are a drip type to be placed on the mouth of a cup and a coffee pack type to be put in the cup for use.

[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 after extraction the filter pack.

[0004]

Therefore, the present invention has the following features. 1. In a simple coffee extractor, a flat bag-type container filter (1) having a flat filter (11) on the front side and a waterproof / heat insulating plate (2) on the back side, which are fitted to each other and have an upper opening (4), is provided. The outer surface (3) of the waterproof and heat insulating plate (2) which is formed and constitutes the entire rear side is a knob portion (5) for picking up the bag type container filter (1) by hand after extracting the upper mouth (4). ), The flat filter (11) having the inner surface (10) of the waterproof and heat insulating plate (2) as the hot water pouring surface (6) is a hard filter, and the waterproof and heat insulating plate (2) on the rear side is also hard. Due to the hardness of the two surfaces of each other, the bag-shaped container filter (1) has the strength to prevent the bag-shaped and mouth-shaped deformation due to the weight of the hot water when pouring hot water into the bag-shaped container filter (1) in the cup (9). This upper opening (4) which is made up is the cup (9) Cup when it is set (9)
Flat filter (11) to be horizontal to the mouth of
The side is low and the side is high waterproof (2) The side is a slanting cut-shaped upper port (4) which is a bag-shaped container filter (1) filled with coffee powder (7) and temporarily attached at the temporary adhesion part (8). A dripper pack made by temporarily adhering the mouth (4).

[0005]

[Operation] When using the present invention, the mouth of the upper mouth (4) which is temporarily adhered is opened and the whole lower part of the pack of the bag-type container filter (1) is put in the cup (9) and hot water is poured into the bag. After putting and extracting, the outer surface (3) which is the side wall surface on the back side of the bag type container filter (1) which is the knob part (5) is manually gripped and the hot water drainer is used by gradually lifting the bag type container filter (1). .

[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 container having a waterproof and heat insulating plate (2) as a flat plate mainly integrated into a single surface, and mating the flat plate filter (11) with each other to form a filter on the front side. The bag-shaped container filter (1) was provided. In addition, the strength of the bag shape retention due to the hardness to prevent deformation of the bag shape and mouth shape due to the weight of the hot water when pouring hot water into the bag type container filter (1) in the cup (9) If it is only put on one side, it becomes hard only on one side and it becomes difficult to fill coffee powder into the bag, and it is difficult to form a bag shape when using for extraction, and if only the filter side is soft, pour hot water. However, in the present invention, the bag shape on the filter surface side is deformed. Therefore, in the present invention, the bag shape supports the weight of the hot water poured into the bag and the shape of the bag and the mouth shape. The bag itself has the strength required for holding the bag due to its hardness. In other words, by dispersing the hardness, the overall bag shape is softened, and when the coffee powder is filled into the bag, the bag shape is formed in the cup, and the extract is used or removed 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 set to be slightly stiff 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, the filter area is large if the entire bag is used as a filter, and it is necessary to reduce the filter area when an appropriate filter is used for coffee extraction. By using only one side of the filter as a filter, the filter area is reduced while securing the necessary bag volume. The waterproof and heat insulating plate (2), which is a flat plate, serves as a knob (5) when the outer surface (3) is taken out from the cup (9), and the inner surface (10) of the knob (5) is filled with hot water in a bag. It also functions as a pouring surface (6) when pouring into the cup, and when the knob (5) is manually gripped from the cup (9), steam rising from the cup (9) and the pack itself when taking out this dripper pack is removed. The waterproof and heat insulating plate (2), which is entirely flat, serves the function of a heat insulating plate that blocks heat and protects 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 a simple coffee extractor, a flat bag-type container filter (1) having a flat filter (11) on the front side and a waterproof / heat insulating plate (2) on the back side, which are fitted to each other and have an upper opening (4), is provided. The outer surface (3) of the waterproof and heat insulating plate (2) which is formed and constitutes the entire rear side is a knob portion (5) for picking up the bag type container filter (1) by hand after extracting the bag type container filter (1). ), The flat filter (11) having the inner surface (10) of the waterproof and heat insulating plate (2) as the hot water pouring surface (6) is a hard filter, and the waterproof and heat insulating plate (2) on the rear side is also hard. Due to the hardness of the two surfaces of each other, the bag-shaped container filter (1) has the strength to prevent the bag-shaped and mouth-shaped deformation due to the weight of the hot water when pouring hot water into the bag-shaped container filter (1) in the cup (9). This upper opening (4) which is made up is the cup (9) Cup when it is set (9)
Flat filter (11) to be horizontal to the mouth of
The side is low and the side is high waterproof (2) The side is a slanting cut-shaped upper port (4) which is a bag-shaped container filter (1) filled with coffee powder (7) and temporarily attached at the temporary adhesion part (8). A dripper pack made by temporarily adhering the mouth (4). The present invention is a bag-type container filter of a single-sided filter (1) in which one surface is a filter and the other surface is a flat plate, and two surfaces are combined.
A bag-type container filter (1) having a flat filter (11) on the front side and a waterproof and heat insulating plate (2) on the entire back side to open the upper opening (4) and form the mouth shape in a circular shape by hand The lower part of the bag-shaped container filter (1) has a smaller cross-sectional area from the horizontal direction because the flat shape is maintained by the rigid action of the two faces of the flat filter (11) and the waterproof and heat insulating plate (2). The overall shape of the bag-type container filter (1) having a smaller volume becomes an inverted conical shape. Therefore, when hot water is poured into the bag-shaped container filter (1) in the cup (9), the volume below the bag-shaped container filter (1) is larger than the amount of hot water accumulated in the cup (9). The occupancy rate in the inside is small, which causes the effect of increasing the drip rate. Further, if the bag-shaped container filter (1) is formed into a bag shape with a downwardly tapered shape and the entire shape of the bag-shaped container filter (1) is further inverted conical, the effect is further enhanced. The bag-type container filter (1) of the present invention is such that the lower part is placed on the bottom of the cup (9) and the upper mouth (4) side is tilted in one direction inside the mouth of the cup (9). ), The flat bag-type container filter (1) in the cup (9) is stabilized in the front, rear, left and right directions. Further, the upper mouth (4) has an overall shape which is positioned horizontally with respect to the mouth of the cup when set in the cup (9) to facilitate pouring hot water into the bag.
Further, since the bag type container filter (1) is a flat type bag type container filter (1), the bag type container filter (1) has a small capacity compared to the outer dimensions, and a drip action occurs due to the capacity difference with the cup (9). I am letting you. The bag-type container filter (1) is based on a planar bag-like shape having two surfaces as a whole, and has an easy-to-manufacture overall shape that matches a machine for filling coffee. The lower part of the bag-type container filter (1) is placed at the bottom of the cup (9), and the bag-type container filter (1) is placed.
This is a method in which the weight of the hot water inside is basically supported by the bottom inside the cup (9). 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-type container filter (1), is provided as the knob portion (5), the knob portion (5) is gripped from the outside and the coffee pack is held by hand. Since the position of the hand is on the outside of the cup (9) or pack when taken out from inside the holding cup (9), the heat rising from inside the cup (9) or inside the pack is not directly received by the hand You can hold the knob directly by hand. Further, since the knob portion (5) is waterproof on the waterproof / heat insulating plate (2) itself, when hot water is poured on the pouring surface (6) located on the outside of the cup (9), the cup (9) is moved from the outer surface (3). Prevents hot water from leaking out. Further, the knob portion (5) provided on the outer surface (3) of the back side wall of the bag-type container filter (1) has a waterproof and heat insulating plate (2) having a waterproof property, so that the coffee liquid may be soiled by the hand. Absent. According to the present invention, a waterproof surface is provided on a flat surface on the back side of the bag portion to configure the knob portion.By enlarging the waterproof surface, generation of steam around the knob portion due to the waterproof action is blocked. This is a knob portion that has a large waterproof and heat-insulating surface to suppress the generation and rise of heat to the hand side having the portion. As shown in FIG. 4 and FIG. 5, instead of the flat filter (11), a bag filter (13) having hardness is provided, and on the back side of the side wall surface, in the left and right end directions of the upper opening (4). It has an extended width and also extends downwards to form a flat shape, and the waterproof and heat insulating plate (1
2) may be provided to form a bag-type 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]

As the dripper pack of the present invention pours hot water directly into the pack, extraction is fast and the bag-type container filter (1) has hardness on both the front side and the back side. The mouth shape of the upper mouth (4) is opened stably, and the compact and simple structure does not require a setting mechanism or the like that extends largely outside the bag-type container filter (1). 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. Since the knob portion (5) is provided on the side wall surface, 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.
