Background

As is known, capsules were originally designed for coffee and have still been used mainly in the field of coffee until now. There are also coffee capsules on the market which are used directly to brew raw leaf tea, but the tea soup is not effective.

However, this form of capsule can be used for reference to simplify the manner of infusing raw leaf tea whilst enabling rapid extraction. The capsules allow for faster extraction than manual infusion because they provide infusion pressure which accelerates the rate of extraction and promotes infusion of the raw leaf tea.

The existing capsule has the defect of poor effect of making tea soup with second or more tea for brewing raw leaf tea. The coffee is extracted once, the raw tea can be extracted for many times, and the raw tea can be extracted for 3-5 times under the condition of manual brewing and can still keep better taste. When the capsule is used for brewing raw leaf tea, the second brewing and more brewing need higher pressure to extract deeper effective substances of the raw leaf tea within the same extraction time.
