Description

Ear-hanging filter bag for brewing tea

The present invention relates to an ear-mounted filter bag for brewing tea leaves by pouring hot water into the tea leaves to release components in the tea leaves.

The method of using a teapot to brew tea leaves can release the original components of the tea leaves to the maximum without hindering the expansion of the tea leaves, but because of the poor post-processing and portability of the tea leaves, tea bags are popular (for example, Patent Document 1) . However, if you use a tea bag, the expansion of the tea leaves will be hindered, so the original taste cannot be brewed. On the other hand, an ear-mounted filter bag for brewing tea has been proposed. Like the ear-mounted filter bag for brewing coffee, the tea leaves are put into the bag from the upper opening. The ingredients in the tea leaves are released by dropping the tea leaves (for example, Patent Document 2 to Patent Document 5). According to the filter bags of Patent Document 2 to Patent Document 5, there is no such thing as a tea bag to seal the tea leaves in a closed space, because the tea leaves can expand toward the upper space, so compared with the tea bag, it can approach the taste of brewing in a teapot. And it is described in Patent Document 2 to Patent Document 5 that the material of the filter bag is to use non-woven fabric. In particular, Patent Document 3, which releases the components in the tea leaves, proposes a leaky tea bag, which is a type in which the bag body is locked from above near the opening edge of the teacup, and the bag body is locked by a specific The filter bag material is formed, and the release time of the ingredients in the tea leaves from the time when hot water is injected into the bag body until the release liquid falls to the bag body can be controlled to a time suitable for brewing delicious tea. Specifically, it is proposed A non-woven fabric is used, which is formed of polyester-based long fibers with an average fiber diameter of 1-20 μm, a basis weight (weight per unit area) of 20-50 g/m ² , a maximum opening diameter of 40-90 μm, and an average opening diameter of 30-60 μm. Thickness 100~200μm, average appearance density 0.16~0.25g/cm ³ . [Prior Art Document] [Patent Document]

[Problem to be solved by the invention]

However, in Patent Document 3, by making the opening diameter, thickness, and density of the nonwoven fabric into a fixed range, the release time of the ingredients in the tea leaves can be kept fixed, and the optimal concentration for drinking can be kept fixed without causing pore blockage. And Patent Document 2, Patent Document 4, and Patent Document 5 only describe the use of nonwoven fabrics.

The purpose of the present invention is to provide an ear-hanging filter bag for brewing tea, which can further help the expansion of the tea when the ingredients in the tea are released, and can easily release the release liquid that contacts the tea from the non-woven fabric while the tea is expanding. .
