[Industrial applications]

 The present invention relates to an improvement of a disposable coffee extractor in which a full-scale drip coffee can be easily enjoyed by simply pouring hot water into a hot water infuser equipped with a coffee pack containing powdered coffee.

[0002]

[Prior art]

 Conventionally, many coffee extractors of this type have been developed. Among them, a coffee extractor consisting of a plastic hot water filling container and a coffee pack mounted inside the container is well known. Has been. In this coffee pack, the upper and lower openings are closed by filter paper, and powder coffee is enclosed between the filters. Then, when using, fit the coffee pack into the bottom opening of the hot water infusion container, place the hot water infusion container on the coffee cup in this state, pour the required amount of hot water into the container, and the hot water will remain in the coffee pack. The mechanism is that it permeates the powdered coffee and is filtered to collect coffee in the coffee cup.

Since such a coffee extractor is a plastic molded product that does not deform even when hot water is poured, it is not so inconvenient to use it indoors such as at home even if it cannot be folded. There is a convenience that the hot water infusion container can be washed and used many times as a disposable.

On the other hand, the sales route has a weak point that it is easily damaged during transportation. Therefore, for a coffee pack that is housed in a protective case for preventing damage or that contains powdered coffee, However, in order to prevent the deterioration of the flavor and dampness of coffee, it is necessary to secretly wrap the film in a gas barrier film, so the whole product is bulky and inconvenient to carry.

Further, like the coffee extractors disclosed in Japanese Utility Model Publication Nos. 1-118725, 2-43935, and 2-48025, it is convenient to store and carry without being folded and bulky. However, there are still practical inconveniences as described below.

Here, an outline of an example of a conventional coffee extractor will be described with reference to FIG. 5, which is a perspective view. In the figure, this coffee extractor is composed of a vertical plate a and a funnel-shaped coffee pack b for storing coffee. The vertical plate a made of cardboard can be folded in half along a fold c. An appropriate number of notches d and e are formed on the lower edge of the vertical plate a so that the vertical plate a can be easily set over the coffee cup. The left and right sides of the coffee pack b can be fixed or attached to the inner surface of the vertical plate a.

When this coffee extractor is used, the vertical plate a is opened along the fold c, and the coffee cup is set on the cup so that the edges of the coffee cup are sandwiched by the cutouts d and e, and set. When pouring hot water, the vertical plate a is folded back due to the momentum of the hot water and the weight of the powdered coffee that has become heavy. Slide close to each other along the edge of the coffee cup, narrowing the opening for pouring hot water, making it difficult to pour hot water. Therefore, if the user inadvertently touches the coffee pack b or the like while trying to keep the opening for pouring hot water wide, the hot water may cause burns. Thus, there was a problem in terms of use.

[0008]

[Problems to be solved by the device]

 The present invention has been proposed in order to eliminate the above-mentioned drawbacks of the related art, and when pouring hot water when making coffee, the pouring opening is not narrowed and the hot water does not overflow outside. The aim is to provide a safe coffee extractor.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, a coffee extractor according to the present invention has a longitudinal joint formed by superposing either one of the left and right sides of a pair of front and rear sandwiching plates, and the other side of the sandwich. Folding plates each having a folding line parallel to the center are connected in a freely bendable manner to form a coffee pack support that is continuous in a cylindrical shape. A cup insertion part projecting to the inside of the folding plate, and a cup outside locking part projecting downward at the center of the bottom of the folding plate. Further, an appropriate amount of powdered coffee is placed in the filter paper inside the coffee pack support. It is characterized in that a coffee pack enclosed in is inserted and one end of the coffee pack is clamped and fixed to the joint.

[0010]

[Action]

 The coffee brewer according to the present invention forms a foldable cylindrical coffee pack support by connecting a pair of sandwiching plates and a folding plate having a vertical folding line formed in the center thereof to form a sandwiching plate and a sandwiching plate. A cup insertion part and a cup outer locking part are formed in the center of the bottom of the folding plate, and a coffee cup made of paper paper containing powdered coffee is sandwiched and fixed at the joint part. Therefore, when using the coffee pack support, unfold it and place it on the top edge of the coffee cup to open the top side of the coffee pack containing the powdered coffee. At this time, the cup insertion part at the center of the bottom of both clamping plates can be set inside the cup, and the outside locking part of the cup at the center of the bottom of the folding plate can be pushed out to the outside of the cup. It is stably placed on the cup. If hot water is poured into the coffee in this state, even if the coffee pack becomes heavy and contains the hot water, and the expanded hot water injection opening is narrowed, the cup outer locking part of the folding plate is located outside the cup. Since it will prevent the return, the opening for pouring hot water will not be narrowed.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a usage state of a coffee extractor according to the present invention. In the figure, the sandwiching plates 1 and 2 are overlapped with each other at one side to form a joint portion 1a which can be mountain-folded in the vertical direction, and the other side of the sandwiching plates 1 and 2 is vertically aligned at the center. A folding plate 3 having folding lines 3a that can be folded in the direction of peaks and valleys is foldably connected along a vertical folding line 3b. A cylindrical coffee pack support A is formed by the two sandwiching plates 1 and 2 and the folding plate 3 which are continuous to be foldable and expandable. All the members of the coffee pack support A 1 are integrally constructed of cardboard that is hygienically waterproofed.

At the central portions of the bottom sides of the sandwiching plates 1 and 2 and the folding plate 3, cup insertion portions 4 and 5 and a cup outer locking portion 6 which project downward are formed, respectively. The lengths of the cup insertion portions 4 and 5 and the cup outer locking portion 6 may correspond to the size of a general coffee cup, as shown in FIG. It should be noted that a plurality of recessed leg portions 7 that are recessed in the opposite direction are formed in the adjacent portions of the cup insertion portions 4 and 5 and the cup outer locking portion 6, but these recessed leg portions 7 are the same as those of the coffee cup. It will be the part that can be placed on the upper edge.

Reference numeral 10 denotes a coffee pack in which powdered coffee 12 is enclosed. The entire surface is made of paper, the upper side of which is overlapped and removably glued, and the vertical side of the coffee pack 10 is It is sandwiched and fixed between the sandwiching plates 1 and 2, and both side portions 11 are secured between the inner walls of the sandwiching plates 1 and 2 by appropriate means such as sticking. Therefore, when the sandwiching plates 1 and 2 are expanded, the coffee pack 10 is opened in synchronism with the expansion, and the stacking stop on the upper side is released to form an opening for pouring hot water.

The coffee pack 10 does not have to have a so-called bag shape. For example, only the lower half part may be a paper filter and the upper half part may be made of paper. It must be confidentially packaged with materials that do not compromise flavor. 13 is a coffee cup.

Since the coffee extractor according to the present invention is constructed as described above, first, when the coffee is put in, the folded coffee extractor is unfolded so that the upper side of the coffee pack 10 is not temporarily glued. When released, it opens together with the sandwiching plates 1 and 2 to form a molten metal opening, and at the bottom edge, three concave legs 7 are formed. The concave leg portion 7 is placed so as to straddle the upper edge of the coffee cup 13, and the folding plate 3 is pulled outward so that the cup outer locking portion 6 is brought out of the coffee cup 13.

Thus, the cup insertion portions 4 and 5 are located inside the cup 13, and the cup outer locking portions 6 are located outside the cup 13 so as to sandwich the cup 13 from each other. Stable installed on top. Next, when the coffee pack 10 containing the powdered coffee is poured from above, the hot water permeates the coffee powder through the filter paper to fill the coffee cup 13.

At this time, even if the powdered coffee 12 in the coffee pack 10 contains hot water and becomes heavy, and the holding plates 1 and 2 return to their original shapes folded together, the lower edge of the folding plate 3 The cup outer locking portion 6 is located outside the coffee cup 13 to prevent the folding plate 3 from displacing inwardly, so that the hot water injection opening is not narrowed, and thereby the hot water is absorbed into the coffee cup. No more worrying about spilling outside.

The above-mentioned coffee pack support of the coffee extractor according to the present invention is conveniently made of a single cardboard as shown in FIG. That is, in FIG. 5, since the folding line 3a is centered symmetrically, the mold can be easily manufactured, and when the outer periphery of both the clamping plates 1 and 2 and the folding plate 3 is punched with a mold by a press or the like. At the same time, the folding line 3a and the mountain folding line 3b can be processed so as to be bendable.

[0019]

[Effect of device]

 As described in detail above, when the coffee extractor according to the present invention is in use, both clamping plates hold a coffee pack containing powdered coffee, and the cup insertion part below the clamping plates is located inside the coffee cup. However, the folding plate can be pulled back and the cup outer locking part of its lower edge can be brought into contact with the coffee cup from the outside, so let's restore the folding plate to the original state of folding with the weight of hot water. Even so, the outer locking portion of the folding plate on the outside of the coffee cup prevents the return of the coffee cup at a position outside, so that the opening for pouring hot water is not narrowed and it is safe.
