Description

  The present invention relates to a coffee extraction cup for extracting coffee through a filter by pouring hot water with coffee powder.

  In the conventional filtration type or funnel type coffee extractor (dripper), it is made of paper containing coffee powder in a synthetic resin or glass filter, or made of metal, or a composite made of synthetic resin and metal. The filter is attached directly to the extractor, or the holder is attached to a container such as a server or a coffee cup, and heated water is poured into the structure to extract coffee. Moreover, in the above-mentioned filter, the cross section of any filter is substantially V-shaped.

Problems that the device tries to solve

  However, this type of coffee extractor (dripper) is made of synthetic resin, metal, or glass and is not equipped with a heat retaining mechanism, and the temperature of the extract is extremely low when coffee is extracted and when coffee powder is steamed. Causes a drop.

  On the other hand, the paper filter has a substantially V-shaped cross section and a convex shape on the lower side, and a gap is formed between the extractor and the paper filter. For the reasons described above, an insufficiently extracted extract will pass and only mottled coffee will be obtained.

  In addition, since the used coffee extractor leaks residual liquid, a container such as a liquid receiving tray is required.

  By providing a heating mechanism that prevents the temperature drop during coffee extraction and when coffee powder is steamed, the temperature drop of the extract can be prevented, but the manufacturing cost is increased and the extractor itself becomes large, thereby obtaining a compact coffee extraction cup. I can't. On the other hand, the gap between the extractor and the filter can be eliminated by integrating the extractor and the filter, but the manufacturing cost is high and it is impossible to manufacture at a reasonable cost. In addition, it is necessary to prepare a container such as a liquid tray, which is troublesome.

  Therefore, the present invention prevents the temperature drop by suppressing extra heat dissipation during coffee extraction and when coffee powder is steamed, and improves the gap between the extractor and the filter, thereby reducing the original cost of the coffee without any spots at a reasonable cost. The object is to extract coffee with umami and prevent liquid leakage without using a container such as a liquid tray.
