Description

Hanging ear filter bag and filter paper

This creation relates to a device for brewing beverages, in particular to a filter paper and a coffee ear bag for filtering coffee powder or tea leaves when brewing coffee.

The coffee hanging ear bag in the prior art has two hanging ears and a filter bag body, and the filter bag body can contain coffee powder; the filter bag body can be roughly divided into a bottom area and an upper area according to the height position of the coffee powder. The portion of the body lower than the height of the coffee powder (that is, the portion contacting the coffee powder) is defined as the bottom area, and the portion of the filter bag body higher than the coffee powder is defined as the upper area.

When brewing coffee, the filter bag body is suspended from the cup with hanging ears, and hot water is poured into the filter bag body from the opening above the filter bag body. After hot coffee extracts coffee bean powder, it passes through the bottom of the filter bag body. Drain into cup.

However, because the filtration resistance of the bottom area of the existing filter bag body is the same as that of the upper area, the bottom area of the filter bag body is covered by coffee bean powder. The coffee bean powder will cause additional filtering resistance to the water flow. When injecting water, the flow rate needs to be carefully controlled so that the water level in the body of the filter bag is approximately flush with the height of the coffee powder (that is, the water level is not higher than the bottom area) to ensure that the water flow will first pass through the coffee powder to complete the coffee bean After the powder is extracted, it flows out from the bottom area of the filter bag. If the flow rate is not carefully controlled during water injection, which causes the water level to be significantly higher than that of coffee powder, most of the water flow will directly flow from the filtration resistance without passing through the coffee powder. The smaller upper area flows out, resulting in insufficient extraction of brewed coffee and affecting the taste.

Therefore, the prior art coffee hanging ear bag needs to be improved.

In view of the aforementioned shortcomings and shortcomings of the prior art, the present invention provides a hanging ear filter bag to facilitate use and improve brewing quality.

In order to achieve the above-mentioned creative purpose, the technical means used in this creation is to design a hanging ear filter bag, which includes:

The distribution density of the block 17 in the upper region 16 may be 1.3 to 1.6 times the distribution density of the low-permeability block 17 in the bottom region 15, but the ratio of the aforementioned distribution density is not limited to 1.3 to 1.6 times.

In this embodiment, the shape of the low-permeability block 17 is circular, but is not limited thereto, and the shape of the low-permeability block 17 may also be a character or a pattern.

Please refer to FIG. 1 further, the aforementioned sealing portion 20 closes the upper opening 12 of the filter bag body 10; a tear line 21 is formed on the sealing portion 20, and the tear line 21 extends to opposite sides of the sealing portion 20; In the example, the tear line 21 is a plurality of slits spaced along a straight line to reduce the strength at the tear line 21. As a result, when the seal portion 20 is pulled, the tear line 21 easily breaks and the seal portion 20 Separate from the filter bag body 10.

Please refer to FIG. 1, FIG. 4, and FIG. 5. The two hanging ears 30 are respectively disposed on opposite sides of the filter bag body 10. This creation can be suspended above the cup by the hanging ears 30. In this embodiment, A plurality of adhesive portions 31 are provided between the mounting ear 30 and the filter bag body 10, and the mounting ears 30 are connected to the filter bag body through the adhesive portion 31. A coating layer is further provided between the adhesive portion 31 and the filter bag body 10 to avoid the adhesive portion 31 The chemicals dissolved into the water during brewing.

Please refer to FIG. 1, FIG. 5, and FIG. 6. When using the hanging ear filter bag of this creation, the sealing portion 20 is torn apart from the upper part of the filter bag body 10, and then the filter bag body 10 is mounted with the hanging ear 30. Hanging above the cup, you can inject a large amount of hot water into the filter bag body 10 at one time; you do not need to carefully control the flow rate when brewing, but you can inject a large amount of hot water into the filter bag body 10 at one time to brew The water flow will first fully extract the coffee bean powder or tea leaves and other contents in the filter bag body 10 before flowing out from the bottom region 15.

Please refer to FIG. 7. The second embodiment of the hanging ear filter bag of this creation is substantially the same as the first embodiment described above, except that the cross-sectional area of the internal space of the filter bag body 10A is from the bottom area 15A of the filter bag body 10A. The bottom 151A gradually increases toward the upper opening 12A, and specifically, the filter bag body 10A has a tapered shape; by this, the upper opening 12A of the hanging ear filter bag is wider, and when a user adds coffee powder or tea to the hanging ear filter bag It is less easy to spill and is more convenient to use.

Please refer to FIG. 8 and FIG. 9. The filter paper of this creation is tapered and has an internal space 11B and an upper opening 12B. The upper opening 12B communicates with the internal space 11B.
