  Hereinafter, the beverage extraction filter and the beverage extraction bag of each embodiment of the present invention will be described by taking, as an example, the case of drip coffee as a raw material from which coffee beans are extracted (extraction raw material).

  As shown in FIG. 1, a beverage extraction filter 1 includes a bag-like filter body 3 having an opening 2 formed on the upper end side, and a prefiltration unit 4 that divides the internal space of the filter body 3 into a plurality of vertical directions. And a multi-drip structure M having a holder 5.

FIG. 2 is a diagram in which the substrates 6 and 7 are superimposed. As shown in FIG. 2, the filter body 3 is formed by overlapping two base materials 6.
The two base materials 6 and 6 are formed in the same shape. The substrate 6 includes a first upper side 6a extending in the horizontal direction, second upper sides 6b and 6b extending obliquely downward from both ends of the first upper side 6a, and second upper sides 6b and 6b. It is formed in a pentagon surrounded by left and right lower sides 6c, 6c extending from each lower end to the top 6d formed on a line orthogonal to the first upper side 6a through the center of the first upper side 6a.

The base materials 6 are arranged to face each other with the sides 6a, 6b, 6c aligned, in a state where the right and left lower sides 6c, 6c are welded and the first upper side 6a and the second upper sides 6b, 6b are released. It is pasted together.
The pre-filtration unit 4 is formed by aligning the sides 7a, 7b, and 7c of the base materials 7 and 7, and welding the lower side 7c. The first upper side 7 a and the second upper side 7 b are formed in the same shape as the first upper side 6 a and the second upper side 6 b of the filter body 3. The lower sides 7c and 7c of the pre-filtration part 4 are formed shorter than the lower sides 6c and 6c of the filter body 3. Further, the angle θ1 formed by the lower sides 7c and 7c is formed larger than the angle θ2 formed by the lower sides 6c and 6c of the filter body 3. As a result, the pre-filtration unit 4 is formed with a shallower inner space than the filter body 3.

The prefiltration unit 4 is sandwiched between the base materials 6 and 6 of the filter body 3.
The first upper side 6a and the second upper side 6b of the filter body 3 and the first upper side 7a and the second upper side 7b of the pre-filtration unit 4 are overlapped so as to substantially coincide with each other.
As shown in FIG. 3, the pre-filtration part 4 and the filter main body 3 are firmly welded, leaving one corner K at the upper end. The upper ends (first upper side 7 a and second upper side 7 b) of the pre-filtration unit 4 form a first opening 2 a that communicates with the internal space of the pre-filtration unit 4.

The vicinity of the non-welded corner K is a part of the first upper side 6a and the second upper side 6b of the filter body 3, and a part of the first upper side 7a and the second upper side 7b of the pre-filtration unit 4. Can be separated from each other, and forms a second opening 2b that communicates with the space formed by the pre-filtration unit 4 and the filter body 3.
The 1st opening part 2a and the 2nd opening part 2b comprise the insertion port into which coffee beans are thrown in, and are formed on substantially the same plane.

  As shown in FIG. 1, the top portion 7 d of the pre-filtration unit 4 is downward from the upper end of the opening of the filter body 3 when the whole from the upper end of the opening of the filter body 3 to the deepest part inside the filter body 3 is 100. It suffices if it is inserted from a depth of 80 (4/5 depth) to a depth of 33 (about one third). In this embodiment, the top part 7d of the pre-filtration part 4 is inserted in the depth of 60 (3/5) to 50 (1/2) from the more preferable opening part upper end.

The beverage extraction filter 1 formed in this manner widens the first opening 2a by separating the first upper sides 7a, 7a and the second upper sides 7b, 7b of the base materials 7, 7 shown in FIG. Then, as shown in FIG.
Specifically, the filter body 3 forms a deep, substantially conical shape that accommodates the pre-filtration part 4. This quadrangular pyramid shape has a structure in which the extract is concentrated at the tip. And the filter main body 3 below the pre-filtration part 4 forms the 2nd drip part M2 which accommodates coffee beans intensively in the lowest part of the internal space, and performs secondary extraction.

The pre-filtration unit 4 forms a substantially quadrangular pyramid shape that is shallower than the filter body 3 and is enclosed in the filter body 3. The quadrangular pyramid shape of the pre-filtration unit 4 has a structure in which the input is concentrated at the tip. This pre-filtration part 4 forms the 1st drip part M1 which performs 1st extraction (previous stage extraction), concentrating coffee beans on the lowest part of the interior space.
The filter body 3 forms a second drip portion M2 that extracts the coffee in a superimposed manner by passing the coffee extracted by the pre-filtration unit 4 through the coffee beans accommodated below.

  The materials of the base materials 6 and 7 contain at least a part of a thermoplastic resin or efficiently take in a thermoplastic resin, and the base materials 6 and 6, the base materials 7 and 7, or the base material 6. The nonwoven fabric etc. which can be easily joined to the base material 7 are used. The base materials 6 and 7 are, for example, mirror-finished and embossed on the entire surface so that the ground coffee beans do not get entangled or cause jamming in the coffee bean filling process. It is preferable that it is a thing with high smoothness. Moreover, the base materials 6 and 7 have water repellency, and it is still better if they have oil repellency. Specific materials for the substrates 6 and 7 include, for example, a thermal bond nonwoven fabric, a spunbond nonwoven fabric, and a resin film.

Alternatively, the base materials 6 and 7 are excellent in the filtration performance of the non-woven fabric such as the thermal bond non-woven fabric and the coffee powder, and do not discharge fine powder, useless oils and fats into the extract, for example, melt blown What bonded non-woven fabric, heat seal paper, etc. may be used.
That is, as the base materials 6 and 7, any material can be adopted as long as it can suitably filter coffee extraction at a desired speed.

The filter main body 3 and the prefiltration part 4 can use the nonwoven fabric of the same or different material.
In the case of using a nonwoven fabric of the same material for the filter body 3 and the pre-filtration unit 4, except that the hot water for steaming coffee beans is high-temperature white water or coffee after extraction, The extraction condition and the extraction condition in the filter main body 3 can be made the same.
When non-woven fabrics of different materials are used for the filter main body 3 and the pre-filtration part 4, coffees having different amounts and properties of coffee beans to be accommodated in the first drip part M1 and coffee beans to be accommodated in the second drip part M2 It can be set as appropriate according to the conditions of the beans themselves.

As a typical example of the case where non-woven fabrics of different materials are used for the filter main body 3 and the pre-filtration part 4, there are cases where the extraction speed in the first drip part M1 and the extraction speed in the second drip part M2 are different. .
Since the nonwoven fabric used can control the extraction speed by the degree of hydrophilicity or hydrophobicity, the porosity, the thickness dimension of the nonwoven fabric, etc., the first drip in the pre-filtration part 4 and the second drip in the filter body 3 It is possible to extract various flavors of coffee by making the speeds the same or different.

  That is, the beverage extraction filter 1 drips coffee from hot water in the first drip part M1, and drip coffee from coffee in the second drip part M2 (in other words, “extract coffee with coffee”). Multi-drip structure M is adopted.

  The holder 5 is fixed to the outer surface of the base material 6 and may be anything as long as it has a locking piece 5b that can be placed on the container 100, but in addition to the locking piece 5b, It is desirable to have a holding portion 5a that can hold the shape of the first opening 2a.

Next, the usage method of the filter 1 for beverage extraction of this invention is demonstrated.
As shown in FIG. 1 or FIG. 2, the beverage extraction filter 1 is formed by flatly folding the base materials 6 and 6 of the filter body 3 and the base materials 7 and 7 of the pre-filtration unit 4 before use, as shown in FIG. One opening 2a is in a closed state. Therefore, first, as shown in FIG. 3, the first opening 2 a is opened in a substantially rectangular shape to form the first drip part M <b> 1 and the second drip part M <b> 2 having a substantially quadrangular pyramid shape. Install.
Then, from the first opening 2a and the second opening 2b, as shown in FIG. 4, the coffee beans X1 are fed to the first drip part M1 of the pre-filtration part 4 and the second drip part M2 of the filter body 3, respectively. , X2.

  Since preparations for starting drip are completed, hot water is poured from the first opening 2a. If it does so, the coffee bean X1 thrown into the 1st drip part M1 will be steamed. At this time, the first drip portion M1 is formed in a substantially quadrangular pyramid shape, and the coffee beans X1 are gathered at the lowermost part of the quadrangular pyramid shape. The poured hot water also flows toward the tip of the quadrangular pyramid shape. Therefore, the whole coffee bean X1 becomes easy to touch hot water and is efficiently steamed.

Since the pre-filtration part 4 is formed with the nonwoven fabric etc. by which the extraction speed was controlled, the coffee bean X1 is fully steamed in the 1st drip part M1. And the extracted coffee passes the pre filtration part 4 slowly, and is dripped at the 2nd drip part M2 directly under.
The coffee dripped from the first drip part M1 is immediately dripped onto the fresh coffee beans X2 in the second drip part M2 without almost lowering the temperature of the hot water because the pre-filtration part 4 is formed inside the filter body 3. .

  As a result, the coffee extracted from the first drip section M1 is steamed more slowly by the filter body 3 whose extraction speed is controlled, and fresh coffee that has been newly steamed into the coffee that has been drip once. Are extracted and overlapped to drip coffee that is rich and very tasty.

That is, the beverage extraction filter 1 employs a multi-drip structure M in which the first drip part M1 and the second drip part M2 are continuously formed in one filter body 3, thereby allowing the coffee beans X to be obtained. It can be subdivided and carefully steamed.
Therefore, the beverage extraction filter 1 does not pass through the filter while the hot water poured as in the past only steams the coffee beans, but passes the coffee beans X1, X2 divided into a plurality of portions, The coffee can be drip while fully drawing out the potential of the coffee beans X1, X2.

  With this structure, the beverage extraction filter 1 has the effect of being able to drip coffee that is richer and more delicious than before even when the same amount of coffee beans X is used. In other words, it is the same as when drip with the conventional coffee filter with a smaller amount of coffee beans than in the conventional case where hot water is passed through the coffee beans only once using a conventional coffee filter that does not have the pre-filtration unit 4. Can drip strong coffee.

  In addition, in further detail, even with a conventional filter that does not have the pre-filtration unit 4, hot water may be poured into the filter a plurality of times in order to obtain a predetermined amount of coffee. This is completely different from the present invention of passing through coffee beans divided into a plurality of times. In a conventional filter that does not have the pre-filtration unit 4, no matter how many times hot water is poured, the coffee passes only once in the filter.

Further, in the present invention, similarly to returning green tea with a light output to the teapot again, after extracting coffee with a conventional filter having no pre-filtration unit 4, the coffee is returned again to the same filter and extracted a plurality of times. It is completely different from the method.
The inventor of the present application has found out that the present invention is capable of brewing coffee with a strength and a taste that cannot be obtained by any of the above methods using a conventional filter. And, as a result of earnest research, the reason why it is possible to brew a coffee that is stronger than the conventional one is that under the multi-drip structure M according to the present invention, coffee beans X are added to each of the first drip part M1 and the second drip part M2. It was found that when the hot water was poured separately, the extraction at the first drip part M1 and the second drip part M2 can be performed slowly over time.

In this way, the beverage extraction filter 1 can produce delicious coffee with a smaller amount of coffee beans than the conventional one, and is advantageous in that it is economical.
Moreover, since the filter 1 for drink extraction forms the pre filtration part 4 in the filter main body 3 unlike the conventional coffee dripper described in patent document 1, when installing in the container 100 shown in FIG. High stability and easy to brew coffee.

  Furthermore, since the beverage extraction filter 1 has a short distance between the first drip part M1 and the second drip part M2, the drip after the first drip is reduced before the heat of the first drip coffee decreases. It can be carried out. That is, the beverage extraction filter 1 can perform the second and subsequent drip at a temperature that is almost the same as the first drip, so that the coffee can be satisfactorily dipped and a very delicious coffee can be brewed. There is an effect that can be.

Moreover, since the filter 1 for drink extraction forms the pre filtration part 4 in the filter main body 3, there exists an effect that it can form compactly as a whole.
In addition, since the beverage extraction filter 1 includes the holder 5, there is an effect that it can be easily installed in the container 100 without using a resin dripper or the like.
The beverage extraction filter 1 may not be provided with the holder 5 as long as it can be installed in the container 100 and a dripper along the shape of the beverage extraction filter 1 can be used.

Moreover, as shown in FIG. 1, using the beverage extraction filter 1, coffee beans (not shown) are accommodated in advance in each of the first drip part M1 and the second drip part M2, and the first opening 2a. And it is good also as the drink extraction bag 30 which sealed the 2nd opening part 2b.
Since such a beverage extraction bag 30 can start a drip just by opening the first opening 2a and setting it in the container 100 as shown in FIG. 3, it can easily brew very delicious coffee. There is an effect that becomes possible.

In said embodiment, although the filter 1 for drink extraction and the drink extraction bag 30 set it as the structure which formed only one pre filtration part 4 in the filter main body 3, two or more pre filtration parts 4 are provided. Also good.
In this case, coffee can be further subdivided and extracted. In addition, there is an effect that one of the pre-filtration units 4 can contain ingredients of elements (for example, other flavors such as vanilla, nutrients, beverages to be blended) that are desired to be added to the coffee.

  In addition, at least one of the first opening 2a and the second opening 2b shown in FIG. 3 is used for notation and marking of lines, characters, etc. that clearly indicate each opening as shown in FIGS. An identification display 20 may be attached, or a tab 70 that facilitates opening may be provided.

Moreover, although the pre-filtration part 4 and the filter main body 3 illustrated the structure connected in the upper end, the outer peripheral surface of the pre-filtration part 4 and the inner peripheral surface of the filter main body 3 are a certain amount toward the downward direction from the upper end of an opening part. The dimensions should be in close contact.
With such a configuration, the pre-filtration unit 4 can be more securely fixed to the filter body 3. In addition, the coffee that has oozed out of the pre-filtration unit 4 can be dropped into the second drip unit M2 along the inner peripheral surface of the filter body 3. Therefore, the coffee beans that have been steamed and spread in the second drip portion M2 can flow downward.
Thereby, the effect that the drip in the 2nd drip part M2 can be performed more effectively is acquired.

  Moreover, the shape of the filter main body 3 and the pre filtration part 4 is not limited to a quadrangular pyramid shape. Specifically, the filter body 3 and the pre-filtration part 4 have the same shape as the reverse truncated cone shape of the filter body 3 as shown in FIG. Only the depth may be shallower than that of the filter body 3, and the filter body 3 may be stacked.

In this case, it is preferable that the tapered outer peripheral surface of the pre-filtration unit 4 is fixed in close contact with the tapered inner peripheral surface of the filter body 3.
By making such a shape, coffee is dripped from the narrowed bottom surface of the first drip part M1, and in the second drip part M2, the dropped coffee is applied to the coffee beans in the second drip part M2 as quickly as possible. The effect that it becomes possible to make it spread to the whole is acquired.

  In addition, the same operation or function as the modification of the embodiment can be obtained. That is, the coffee that has oozed out from the tapered surface of the pre-filtration unit 4 falls down along the inner peripheral surface of the filter body 3. As a result, the coffee beans that have been steamed in the second drip portion M2 and spread on the inner peripheral surface of the filter main body 3 can be made to flow again below the filter main body 3. Therefore, the beans in the second drip part M can be steamed together as much as possible below, and the coffee beans that have been added are brought into contact with the liquid dripped from the first drip part M1 so that coffee with a higher concentration and deeper taste can be obtained. The effect that it can drip is acquired.

  Although not shown, the filter body 3 has a conical shape and the pre-filtration part 4 has a truncated conical shape, or vice versa, and the filter body 3 has a reverse-conical shape, and the pre-filtration part 4 has a circular shape. Etc. may be used. By making such a shape, a beverage can be dripped quickly from the pre-filtration unit 4, or a coffee in which the bottom of the truncated cone shape is dripped on the whole coffee beans housed in the lower part of the filter body 3 is dripped. The effect that it becomes easy to do is acquired.

Alternatively, as shown in FIG. 6, the filter main body 3 is formed into a substantially flat bag shape with a substantially quadrangular prism shape (rectangular cross-sectional view rectangular shape) or a front view rectangular shape, and the pre-filtration unit 4 has a smaller depth than the filter main body 3. It may be formed in a somewhat flat bag shape having a prismatic shape or a rectangular shape in front view. By setting it as such a structure, the effect that the double bag-shaped drink extraction filter 1 which comprises the 1st drip part M1 and the 2nd drip part M2 can be produced simply is acquired.
That is, as shown in FIG. 7, a rectangular sheet 50 is folded in a Z shape (or an inverted Z shape) from one end 50a side, and finally the other end 50b covers the one end 50a, and both side portions 50c, By appropriately heat-sealing and cutting at 50d, the beverage extraction filter 1 can be easily produced from one sheet.

  Alternatively, as shown in FIG. 8, the filter main body 3 and the pre-filtration part 4 are made into a home base type, and the lower tip of the first drip part M1 is formed in substantially the same shape as the lower tip of the second drip part M2. May be. By setting it as such a structure, the fusion | melting part of the vertical direction of the filter main body 3 and the pre filtration part 4 is set largely, and the pre filtration part 4 becomes easy to hang down with the weight of coffee beans and hot water. The effect that it can prevent is acquired. Further, as described above, the coffee dripped from the first drip portion M1 can prevent the coffee beans from spreading in the second drip portion M2.

  That is, in order to steam the coffee well, the filter main body 3 and the pre-filtration unit 4 are preferably shaped so that the coffee beans can be easily touched with hot water as much as possible, but the hot water is passed through all the subdivided coffee beans. As long as coffee beans can be steamed carefully and repeatedly, the shapes of the filter main body 3 and the pre-filtration unit 4 at the time of three-dimensional setting are not particularly limited.

Further, in the above embodiment, the pre-filtration part 4 has a bag-like structure, but the present invention is not limited to this, and as shown in FIG. The partition member 35 may partition the internal space in the vertical direction. In this case, the upper part of the partition member 35 is the first drip portion M1, and the lower part of the partition member 35 is the second drip.
Also in this case, the beverage extraction filter 1 can exhibit the same operations and effects as the above embodiment.
