Description

The present invention relates to a tea filter that extracts tea by pouring hot water into the added tea leaves.

The method of brewing tea using a teapot can extract the original ingredients of tea to the maximum without hindering the swelling of tea leaves, but tea packs are widespread because of lack of residual treatment and portability of tea leaves (for example, patents). Document 1).
However, when a tea pack is used, the swelling of tea leaves is hindered and the original taste of tea is inferior.
On the other hand, similarly to the coffee filter, a tea filter has been proposed in which tea leaves are put into a bag through an upper opening and tea is extracted by pouring hot water into the put tea leaves (for example, Patent Document 2 to Patent Document 2). 5).
According to the filters described in Patent Documents 2 to 5, unlike the tea pack, the tea leaves are not enclosed in the closed space, and the tea leaves can swell in the upper space. Therefore, a teapot is used as compared with the tea pack. The taste can be similar to that of the teapot.
Further, Patent Documents 2 to 5 describe that a non-woven fabric is used as a filter material.
In particular, in Patent Document 3, a drip-type tea bag for extracting tea is of a type in which the bag body is hooked upward from the vicinity of the opening edge of the tea cup, and when the bag body is formed from a specific filter material, the bag body becomes a bag body. It is said that the tea extraction time from the start of pouring hot water until the extract drops off the bag body can be controlled to a time suitable for making delicious tea. Specifically, polyester long fibers with an average fiber diameter of 1 to 20 μm. Use a non-woven fabric having a grain size of 20 to 50 g / m ² , a maximum opening diameter of 40 to 90 μm, an average opening diameter of 30 to 60 μm, a thickness of 100 to 200 μm, and an average apparent density of 0.16 to 0.25 g / cm ³ . Is proposing.

However, Patent Document 3 keeps the tea extraction time constant, does not cause clogging, and keeps the strength at the time of drinking constant by keeping the opening diameter, thickness, and density of the non-woven fabric within a certain range. be.
Further, Patent Document 2, Patent Document 4, and Patent Document 5 merely describe that a non-woven fabric is used.

It is an object of the present invention to provide a tea filter that further assists the swelling of tea leaves during tea extraction and makes it easier for the extract that comes into contact with the tea leaves to flow out of the non-woven fabric together with the swelling of the tea leaves.

The tea filter of the present invention according to claim 1 has an arcuate upper side formed between a pair of side side portions 11 having an upper end 11u separated from the lower end 11d and the upper end 11u of the pair of the side portions 11. The nonwoven fabric sheets 10A and 10B having the portions 12 and the lower side portions 13 formed between the lower end portions 11d of the pair of the side portions 11 are superposed, and the side portions of the pair of the nonwoven fabric sheets 10A and 10B are overlapped. 11 is joined, and the lower side portions 13 of the pair of nonwoven fabric sheets 10A and 10B are continuously or joined to form a bag body 10 having an opening between the pair of arcuate upper side portions 12, and a pair. Locking members 20A and 20B are arranged on the nonwoven fabric sheets 10A and 10B, respectively, and by hooking the pair of locking members 20A and 20B to the edge of the container 1, one of the arcuate upper side portions 12 and the other The opening is formed so as to be separated from the arc-shaped upper side portion 12, the tea leaf 2 is charged into the bag body 10 from the opening, and hot water is poured into the charged tea leaf 2 to extract tea. The fiber mesh of the nonwoven fabric sheets 10A and 10B is laterally oriented, and the fiber mesh is expanded downward by the tea leaves 2 and the hot water at the time of extracting the tea.
According to the second aspect of the present invention, in the tea filter according to the first aspect, the first reinforcing members 30A and 30B are attached along the arc-shaped upper side portion 12, and the first reinforcing members 30A and 30B are attached to the first reinforcing members 30A and 30B. The second reinforcing members 40A and 40B extending toward the lower side portion 13 are attached to the pair of the nonwoven fabric sheets 10A and 10B, respectively, and the lower ends 11d of the second reinforcing members 40A and 40B are set to a predetermined height from the lower side portion 13. By the way, the first reinforcing members 30A and 30B and the second reinforcing members 40A and 40B are used as non-stretchable materials, and the spread of the fiber mesh is restricted by the second reinforcing members 40A and 40B, and the tea is extracted at the time of extraction. The spread of the fiber mesh from the lower end 11d of the second reinforcing members 40A and 40B to the lower side portion 13 is larger than that from the lower end 11d of the second reinforcing members 40A and 40B to the arc-shaped upper side portion 12. It is characterized by being enlarged.

According to the present invention, by making the fiber mesh of the non-woven fabric sheet horizontal, the fiber mesh spreads at the position where the tea leaves are present, which helps the tea leaves to swell and the hot water is more likely to flow out than the position where the tea leaves are not present. Therefore, the extract that is in contact with the tea leaves can be preferentially discharged, and it is easy to extract the original components of the tea.
