器に比較して大きな問題点である。One disadvantage of this container-type filter is that the main body is formed in a cup shape for storing hot water and is bulky, as compared with the filter supporting the storage section. In addition, the production cost is high despite the fact that it is disposable, and it is difficult to dispose the material because of the material. Among them, the bulky point when storing and storing,
This is a big problem in comparison with a storage unit supporting type filter that can be folded and made compact because it takes up space when transporting and displaying at a store.

器本体内部に収納するようにしたものである。To solve this problem, for example, coffee extractors described in Japanese Utility Model Publication No. 5-10766 and Japanese Utility Model Publication No. 5-40843 have been proposed. The former provides a vertical fold on the peripheral surface of the lower half of the container body, forms a fold line on the upper edge of this vertical fold, and provides a radial horizontal fold on a step portion connecting the coffee storage section, Utilizing the vertical and horizontal folds and the fold line, the lower half peripheral portion of the container body can be bent so that the container body is folded in two, and the coffee storage portion is stored inside the container body.

An annular concave groove is formed on the outer peripheral edge, and the diameter is reduced by using a vertical fold, and the lower half of the container body is folded inside the upper half with the fold line and the annular concave groove as a base point for folding, and a coffee storing section is formed. In addition, it can be stored and folded.

くてはならないことである。These two proposals are to reduce the volume by half and reduce the size by folding the lower half of the cup-shaped container body toward the inside of the upper half. The tension state can be eliminated. However, the problem here is that it is necessary to form vertical and horizontal folds on the peripheral surface to fold the container body, and it is necessary to form a fold line at the upper edge of the vertical folds. In the latter proposal, the annular groove must be formed.

ればならない問題がある。The formation of the vertical folds and the horizontal folds, and the formation of the fold line, the annular groove, and the like are inevitable because both of the above proposals select the rigid synthetic resin material to form the extractor. Although it is a means adopted in the above, the shape of the fold, the fold line, the mutual positional relationship of the annular groove, and the shape, the form of bending is specified by the size,
In addition, since the vertical and horizontal folds, or the fold and the fold line, and the fold and the annular groove are designed to cooperate and bend, the above-mentioned parts are balanced during operation. However, there is a problem that the user has to perform a folding or stretching operation.
