DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a coffee brewer,
More specifically, the present invention relates to a disposable coffee extractor that can easily extract full-scale coffee for one person by pouring boiling water.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Application Laid-Open No. 58-1851.
As described in Japanese Patent Publication No. 47 or No. 5-13324, a filter formed by sticking filter paper between supports formed of cardboard and capable of being formed into a tubular shape,
Tools that can easily extract full-fledged coffee, such as a simple coffee extractor with a coffee pack in which a bag of coffee is stored in a bag formed of filter material, are installed. Already known.

[0003]

However, the coffee extractor described in Japanese Utility Model Application Laid-Open No. 58-185147 has the feature that it can be used several times continuously. Not only must the coffee pack containing the powder be prepared, but the coffee liquor must pass through the coffee pack filter material and the coffee extractor (filter), which increases the coffee extraction time. In addition, hot water is indirectly poured into the coffee powder through a filter material, so that the aroma and flavor are impaired.

[0004] Such a drawback is that a bag made of a filter material containing coffee powder is mounted on a support, as in a filter device described in Japanese Utility Model Publication No. 5-13324, and the filter material is used at the time of use. Can be improved by opening and opening the seal portion, and pouring hot water directly into the coffee powder from the opening portion. However, in such a filtering device, since the sealing portion of the bag body is weakly adhered so as to be easily peeled and opened, a part of the sealing portion is opened when an external force is suddenly applied in a non-use state. There is a concern that coffee powder may spill out of the bag, so care must be taken when handling. In addition, since the opening form of the strip (exterior body) at the time of use is a hull shape, the hot water has to be injected into the center part inevitably, and it is difficult to uniformly extract the coffee liquid from the coffee powder.

According to the present invention, the inconvenience of the conventional simple coffee extractor as described above is improved, and when not in use, the opening of the coffee pack is firmly connected to the outer casing constituting the filter. An object of the present invention is to provide a coffee extractor in which a bag of a coffee pack has a large opening so that hot water can be easily poured and hot water can be evenly poured into coffee powder.

[0006]
