Filter bag

This creation relates to a filter bag, and more particularly to a filter bag for brewing coffee.

Nowadays, "coffee" is a favorite drink of most people, and as people's requirements for food are gradually improved, the quality and convenience of coffee are gradually being paid more attention. The common method of brewing coffee includes placing the bag-shaped filter paper in the filter cup by means of paper drip filtration, and then filling the coffee powder in the bag-shaped filter paper, and directly pouring the coffee powder into the hot water, and the water passes through the coffee powder. Thereafter, the extracted coffee (extract) is discharged from the bag-shaped filter paper, thereby punching out the coffee.

In order to make it easier for the drinker to enjoy the coffee, the market now offers a filter-type coffee, which forms a filter bag with a water-permeable sheet, the filter bag is filled with coffee powder, and the filter bag has a hanging on both sides. The hanging structure can directly hang the hanging structure on the edge of the cup body. When the user brews, the hot water is directly poured into the filter bag to extract the coffee.

Whether or not hot water has a uniform shower coffee powder is one of the main reasons that affect the flavor of coffee. However, whether it is a traditional bag filter paper or a filter bag for filter-type coffee (hereinafter collectively referred to as a filter bag), when brewing, liquid can flow out from any place in the filter bag, so some hot water may not pass adequately. The coffee powder flows out of the filter bag, causing the coffee (extract) flowing out of different areas of the filter bag to have different extraction concentrations. The uneven extraction concentration further affects the flavor of the coffee.

The problem to be solved by the present invention is to solve the problem that the conventional bag-shaped filter paper or the filter bag has uneven extraction and uneven extraction concentration.

In order to solve the above problems, the present invention provides a filter bag which is disposed on a cup body by a supporting member, and the filter bag includes a first water permeable area, a second water permeable area and a closing portion. One end of the second water permeable area is connected to the first water permeable area, and the second water permeable area has a water permeability greater than the first water permeable area. The closure connects the other end of the second water permeable zone.

In an embodiment of the present invention, the second water permeable area is closer to the closed portion than the first water permeable area.

In one embodiment of the present invention, the filter bag is formed by stacking a plurality of layers of non-woven fabric, and the fiber density of the non-woven layers determines the water permeability of the first water-permeable zone and the second water-permeable zone.

In one embodiment of the present invention, the fiber density of the first water permeable zone is greater than the fiber density of the second water permeable zone.

In an embodiment of the present invention, the thickness of the first water permeable zone is greater than the thickness of the second water permeable zone.

In an embodiment of the present invention, the filter bag further includes an opening at one end relative to the closure.

In one embodiment of the present invention, the filter bag further includes a hand tear line located at an end relative to the closure.

In an embodiment of the present invention, the filter bag further includes a third water permeable area, the third water permeable area is connected to the opening or the tear line, and the first water permeable area is connected to the third water permeable area and the second water permeable area, and the third water permeable area The water permeability of the area is smaller than the first water permeable area.

In one embodiment of the present invention, the support member is attached to the outside of the filter bag.

With the above embodiment, the filter bag of the present invention can at least achieve the following advantages: by the difference in water permeability between the first water permeable zone and the second water permeable zone, the manufacturer can control where the liquid flows out. Moreover, the closing portion is connected to the other end of the second water-permeable region, that is, the second water-permeable region having a larger water permeability is closer to the closing portion, thereby allowing the liquid to flow through the brewing body (such as coffee powder) sufficiently and uniformly. Its extract The filter bag is concentrated from the second permeable zone to maintain the extraction concentration of the extract.

In addition, the paper layer 102 of the present embodiment has a plurality of holes for penetrating the liquid. In the present embodiment, different fiber densities are generated by stacking different numbers of paper layers 102 in different regions. For example, as shown in FIG. 3, the fiber sheet 10 of the present embodiment includes three paper layers 102 of different lengths, and the number of paper layers 102 (eg, two sheets) formed in the first water permeable area 14 after stacking is larger than The number (for example, one) of the paper layers 102 located in the second water permeable area 15 The thickness of a water permeable zone 14 is greater than the thickness of the second water permeable zone 15, and the fiber density of the first water permeable zone 14 is greater than the fiber density of the second water permeable zone 15. It should be noted that the number of the non-woven fabric layer 101 and the paper layer 102 shown in FIG. 3 is for illustrative purposes only, and the present invention does not limit the number thereof.

In other embodiments, the paper layer 102 of different numbers or sizes of holes may be adhered to different regions to form different water permeability, and the creation is not limited. For example, the paper layer 102 corresponding to the first water permeable area 14 has a small number of holes or a small shape, and the paper layer 102 corresponding to the second water permeable area 15 has a large number of holes or a large shape. The water permeability of the second water permeable area 15 is made larger than the water permeability of the first water permeable area 14.

Preferably, the filter bag 1 of the present embodiment further includes a third water permeable area 16 disposed at a position adjacent to the opening portion 11 or the tear line 13, and the first water permeable area 14 is connected to the third water permeable area 16 and the second water permeable area. District 15. Regarding the water permeability, the water permeability of the third water permeable area 16 is smaller than the water permeability of the first water permeable area 14. In other words, the water permeability is as low as high in order to be the third water permeable zone 16, the first water permeable zone 14, and the second water permeable zone 15, that is, the closer to the closed portion 12, the higher the water permeability.

As described above, the present embodiment determines the water permeability of different regions by the fiber density of the fiber sheet 10, for example, stacking different numbers of paper layers 102, and the thicker stack has higher fiber density and lower water permeability. Therefore, the thickness of the third water-permeable region 16 is greater than the thickness of the first water-permeable region 14, and the thickness of the first water-permeable region 14 is greater than the thickness of the second water-permeable region 15. For other details, please refer to the foregoing, and no further details are provided herein.

Referring to FIG. 2, the support member 2 of the present embodiment is a hanging structure, and includes two U-shaped support portions 21, and the inner sides of the two support portions 21 are respectively connected to the outer side surfaces of the filter bag 1, respectively. Preferably, the support portion 21 is connected to the outside of the third water-permeable region 16, and the support portion 21 may be attached to the third water-permeable region 16 of the filter bag 1 with an edible cement. Further, the U-shaped support portion 21 can hang the filter bag 1 on the cup edge 91 of the cup body 9, so that the user can directly brew the brewing body (coffee powder) in the filter bag 1. It should be noted that the technical feature of the present invention is that the first water permeable area 14 and the second water permeable area of the filter bag 1 have different water permeability. 15, the configuration of the support member 2 is not limited. In other embodiments, the support member 2a may also be a lug-type suspension structure as shown in FIG. 4, and FIG. 4 is a schematic view of another embodiment of the support member shown in FIG. 2. It should be noted that the filter bag 1 shown in FIG. 4 is different from the configuration shown in FIG. 1 and FIG. 2, and is denoted by the same component number.

Referring to FIG. 2, when the filter bag 1 is placed on the cup 9 by the support member 2, the second water permeable region 15 having the highest water permeability is close to the cup bottom 92, if the user puts liquid (such as but not limited to water, The milk is poured into the filter bag 1 at the opening portion 11, and the liquid contacts the brewing body. At this time, the brewing body and the liquid are filled in the second water permeable area 15 and the part of the first water permeable area 14. When the liquid contacts the brewing body, the liquid can extract the substance of the brewing body and form an extract, for example, extracting the coffee (extract solution) by using water, since the water permeability of the second water permeable area 15 is greater than that of the first water permeable area 14 The extract is mostly discharged from the second water permeable zone 15. That is, after the poured liquid can flow through the brewing body sufficiently and uniformly, and the substance of the brewing body is sufficiently extracted, the extract is concentrated in the second water permeable area 15 to flow out. In this way, the concentration of the extract can be maintained, for example, to maintain the extraction concentration of the coffee, thereby maintaining the flavor of the coffee.

Moreover, when the user pours more liquid into the filter bag 1, the water pressure in the filter bag 1 is larger, and the liquid in the first water permeable area 14 can still flow out after contacting the brewing body here, so The extract still has a certain extraction concentration. The first water permeable area 14 has a certain degree of water permeability (only need to be smaller than the water permeability of the second water permeable area 15), and the design can also avoid the problem that the brewing body is in contact with the liquid for a long time, thereby causing a change in flavor.

In general, when there is a large amount of liquid in the filter bag 1, the overall water pressure is high at this time, so that the brewing body can dissolve a large amount of the extract, and most of the extract flows out from the second water permeable area 15 to The cup body 9, a small portion of the extract is discharged from the first water permeable zone 14 to the cup 9. When the liquid in the filter bag 1 is small, the liquid can slowly flow through the brewing body of the first water permeable area 14 and then flow through the brewing body of the second water permeable area 15, and the extract liquid flows out again through the second water permeable area 15. To the cup 9.

As described above, the support portion 21 is connected to the outside of the third water-permeable region 16, and the water permeability of the third water-permeable region 16 is small. When the liquid is poured into the filter bag 1, the liquid is not easily discharged from the third water-permeable region 16, in other words, Therefore, the liquid does not easily pass through the edible bonding agent, thereby preventing the liquid from dissolving the plasticizer or the like which is not recommended for consumption.

FIG. 5 is a schematic view of a second embodiment of the filter bag of the present invention, which is shown in FIG. 5. The filter bag 1a of the present invention may also be a bag-shaped filter paper, and may be disposed on the cup body by a supporting member such as a filter cup. Of course, the filter bag 1a of the present embodiment also includes an opening portion 11a, a closing portion 12a, a first water permeable portion 14a, and a second water permeable portion 15a. One end of the second water permeable area 15a is connected to the first water permeable area 14a, and the water permeability of the second water permeable area 15a. is greater than the water permeability of the first water permeable area 14a. The closing portion 12a connects the other end of the second water permeable area 15a. Therefore, it is also possible to control the concentration of the extract concentrated in the second water-permeable area 15a, and the extraction concentration of the extract flowing out in different areas, and to maintain the flavor of the coffee when the extract is coffee. For the related technical content of the different water permeability of the first water permeable area 14a and the second water permeable area 15a, reference may be made to the first embodiment, and no further details are provided herein.

In summary, the filter bag provided by the present invention has at least the following advantages: by the difference in water permeability between the first water permeable zone and the second water permeable zone, the manufacturer can control where the liquid flows out. Moreover, the closing portion is connected to the other end of the second water-permeable region, that is, the second water-permeable region having a larger water permeability is closer to the closing portion, thereby allowing the liquid to flow through the brewing body (such as coffee powder) sufficiently and uniformly. The extract is concentrated from the second permeable zone and flows out of the filter bag to maintain the extraction concentration of the extract. When the extract is coffee, the flavor of the coffee can be further maintained.
