DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coffee extractor in which hot water is poured into a coffee filter in which coffee powder is stored in advance and coffee extracted is stored in a cup.

[0002]

2. Description of the Related Art An apparatus for extracting coffee by pouring boiling water into a filter containing coffee powder is disclosed in Japanese Examined Patent Publication No. 5-68246. No. 6,086,045.

In the filter disclosed in the above-mentioned prior art, for example, a predetermined amount of coffee powder is put in a resin case, and the upper and lower portions are closed with water-permeable paper or mesh resin mesh. After pouring into the coffee grounds, the extracted coffee falls from the lower mesh and is stored in the cup.

[0004] Such a filter can easily extract coffee from anywhere by simply pouring boiling water without using a large-sized coffee machine. Is useful for those who love coffee.

[0005]

As described above, it is possible to easily drink delicious coffee from anywhere with only boiling water, but the most difficult point is that the filter after extraction (disposal) is troublesome. is there.

More specifically, since the case is made of synthetic resin and the ground coffee powder becomes flammable, it is necessary to separate each of them and separate them into plastic waste and combustible waste for disposal. In addition to being troublesome, the protruding parts touched the hands during separation and became dirty, and the protruding parts were scattered on a table or the like, which required a lot of cleaning.

[0007] For these reasons, paper filters have been used which can easily discard the filter after extraction as a combustible material.

[0008] Paper filters are certainly convenient at the time of disposal, but apart from the fact that coffee powder touches the hands,
As a new problem, there is a disadvantage that the space occupied by the filter when placed in a garbage bag or the like becomes large.

The present invention does not stain the table or the surroundings due to dirty hands or coffee powder flowing out, and reduces the space occupied by the filter containing the coffee powder when disposing of the filter.

[0010]

According to the present invention, there is provided a coffee filter which is mounted on an upper portion of a cup and in which an extract is stored in the cup by pouring, wherein the coffee filter comprises a storage bag for accommodating coffee powder, The storage bag is constituted by a flange that supports the outer peripheral edge, and at least two folds are provided in parallel with the peripheral edge of the flange.

The fold is formed in a V-shape or a U-shape on the upper surface of the flange and directed upward, and the flange is bent by valley fold.

[0012]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the coffee extractor of the present invention, FIG. 2 is an overall sectional view of the same when placed on a cup, and FIG. 3 is an explanatory view showing a state at the time of disposal.

[0013] (1) is a general-purpose paper cup used for a vending machine, and has a curled outwardly curled portion (2) at the upper peripheral edge. The size of this cup has an upper inner diameter of 68 mm, a lower inner diameter of 48 mm, and a height of 73 mm, and a content suitable for drinking normal coffee is about 150 ml.

(3) A coffee filter which is placed on the upper part of the cup (1) and stores the extract (coffee) in the cup by pouring, is made of water-permeable paper, and has a fine mesh on the upper and lower sides. It comprises a storage bag (4) projecting downward and a ring-shaped flange (5) made of thick paper for fixing the periphery of the upper and lower bases of the storage bag. The diameter is set to be longer than the outer diameter of the edge winding portion (2).

As shown in FIG. 1, the flange (5) has two folds (6) parallel to the region where the peripheral edge faces each other.
(6), (7) and (7) are provided. The interval between adjacent folds is determined according to the outer diameter of the flange (5), and is generally wider when the outer diameter is larger.
If smaller, narrow it.

Although this will be described later, the folds (6) and (6)
(7) When the flange (5) is bent inward from (7), the interval is basically set so that the coffee powder does not fly out due to the overlapping portion of the bent left and right flanges.

Of course, the folds (6), (6), (7) and (7) may be provided on the upper surface of the flange (5), and a plurality of sets may be provided at a plurality of locations toward the center of the flange (5).

The folds (6), (6) and (7)
Each of (7) is formed on the upper surface of the flange (5) in a V-shape or U-shape facing upward.

Referring to the case of extracting coffee, FIG. 2 shows a coffee filter (3) in which coffee powder (8) corresponding to a required coffee extraction amount is stored in a storage bag (4). Is placed on the upper part of the cup (1) as described above, but at the time of placing, the flange (5) is placed on the upper part of the rim part (2), and the flange (5) is placed on the rim part (2). Jumps out slightly more.

As shown in FIG. 2, the lower peripheral edge of the storage bag (4) abuts along the wall surface inclined inward from the upper part to the lower part of the cup (1). 9) goes to the center of the cup (1).

When hot water is poured from above the coffee filter (3) in the above-described state, it penetrates into the coffee powder, and the extracted coffee falls from the lower end and is stored in the cup (1).

When the coffee extraction operation is completed, after the coffee filter (3) is sufficiently drained, the coffee filter (3) is taken out by holding the flange (5), and both sides of the flange (5) are held. Crease (6)
(6), (7) After being raised upward based on (7), it is bent inward (valley fold), and the opposite sides of the flange are overlapped as shown in FIG.

In a state where both sides of the flange (5) are overlapped, as shown in FIG. 3, the storage bag (4) is turned up and the overlapped portion (X) on both sides of the flange is coffee. This prevents a gap between the powder and the inner peripheral edge of the flange (5).

[0024]

As described above, according to the present invention, the coffee filter is constituted by a storage bag for storing coffee and a flange for supporting the outer peripheral edge of the storage bag, and the peripheral edge of the flange has at least two parallel folds. Because it is provided with
At the time of coffee extraction, the extraction work can be easily performed simply by placing a coffee filter on the top of the cup and pouring hot water.

In particular, after the coffee is extracted, the flanges are bent inward along the folds and overlapped,
The upper surface of the coffee filter is covered with a flange to prevent the coffee powder from jumping out and to prevent the coffee powder from touching a finger.

After the flange of the coffee filter is bent, the overall outer diameter becomes small, so that even if it is put in a garbage bag or a garbage bag, it does not occupy a large space and can store more garbage.

Further, the flange has a handle function that can be used by hand to set and remove the coffee filter from and into the cup.

Further, since the fold is formed in a V-shape or U-shape upwardly on the upper surface of the flange and the flange is bent by valley fold, the flange is bent from a predetermined position. In addition, the predetermined areas of the flanges can be overlapped with each other, and the bending is simple and accurate.
