Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a beverage brewing container. For more information, see Regular Coffee, Beni A filter-equipped extractor that allows you to easily extract tea, Japanese tea, etc. inside the container. Regarding the dispensing container.

0002

[Conventional technology]

Traditionally, the following methods have been used to easily extract coffee, black tea, Japanese tea, etc. There is a way. First, place a small sheet of filter material such as paper, textile, or non-woven fabric. It is made into a bag and contains regular coffee, black tea, Japanese tea, etc. before being extracted. A tea bag method filled with an extract is generally well known. Also, cup capacity Place filters and the material to be extracted on top of the container, and pour boiling water over the material to extract. There is also a method in which the extract passes through a filter and falls into a cup container.

0003 However, the method known as the tea bag method is usually used in cup containers. Put a small bag of regular coffee, black tea, Japanese tea, etc. inside and pour boiling water over it. Although it is possible to extract more easily, there are the following problems. In other words, the substances to be extracted, such as regular coffee and black tea, are inside the filter pouch. Because the filter is packed, there is not enough space inside the filter, and the extracted material swells. , elongation, expansion, and other phenomena are restricted. Therefore, when stirring the container, However, by only mixing the outside of the filter pouch, most of the material to be extracted inside the pouch is mixed. It is difficult to get a truly effective extraction without stirring, and longer extractions are unpleasant. This is a big problem as it tends to produce bitterness and astringency, which spoils the flavor.

0004 In addition, as a method for expanding the internal volume of this filter pouch, JP-A-62-2 No. 20461 exists, but the effect of slightly increasing the internal volume of the sachet for extraction is Although there are some, it is still insufficient. In addition, during production, the sachets contain ingredients other than the extracted material. There is a problem with the complexity of having to put things in there. You can also use the filter on the top of the cup container as a way to extract regular coffee. and regular coffee to be extracted, and pour boiling water over the extracted material. A known method is to drop the extract into a cup container through a filter. This method involves attaching a coffee paper filter to a funnel-shaped holder. method or Japanese Utility Model Publication No. 60-7623, Publication of Utility Model Application No. 62-66714, etc. There is a simple extractor disclosed in

[0005] However, in any of the above methods, the filter part and the extracted material are placed in a cup container. Since it is characterized by being placed at the top of the cup, a separate cup container is naturally required. Become. Therefore, it lacks compactness and is inconvenient to carry and portability. Also, At the same time, in both methods, the extractable material (ground powder) is extracted by the natural fall of boiling water. - Particle size of beans), cultivation status, filter accuracy, installation condition, etc. The major problem is that the degree of extraction varies greatly depending on the type of product, and the user cannot adjust it. There is an issue.

[0006]

[Problem that the idea aims to solve]

This invention solves the conventional problems as mentioned above, enables effective extraction, and improves user experience. You can adjust the extraction level according to your preference, and it is more compact and inexpensive. The object of the present invention is to provide an extraction container consisting of a.

[0007]

[Means to solve the problem]

That is, the present invention provides an extraction method in which a shaped filter (2) is inserted into a cup (1). a container, the shaped filter having a shape that contacts the bottom surface of the upper cup; The extraction container is characterized in that it also has a flange portion (3). The cups used in this invention include paper cups, foamed polystyrene resin molded cups, and or is made from synthetic resin such as polystyrene or polypropylene resin. Ru. Any cup container that can hold enough hot water for about one person will suffice, depending on the material and capacity. There are no particular limitations. Preferably a disposable cup Bye.

[0008] The molded filter used in this invention has a shape that can be inserted into the cup and makes contact with the bottom surface. It is necessary that Molded filters are synthetic filters with filter performance and the ability to be stretch-molded. It can be inserted into the cup from sheet materials such as woven, knitted or non-woven fabrics made of fibers. It is preferable that the material be stretched and molded into a shape that is substantially in contact with the bottom surface.

[0009] The shape that contacts the bottom of the cup means that at least the bottom of the cup has a molded film. The bottom of the turret comes into contact with it. The material to be extracted is extracted in the extraction container where the bottom of the cup of the present invention and the bottom of the molded filter are in contact with each other. The user can perform extraction effectively. The reason is that it touches the bottom of the cup. A molded filter with a shape of The object can fully come into contact with almost the entire amount of hot water poured into it, causing it to swell, elongate, and expand. It becomes difficult to pass through the filter. Therefore, the user can freely select the You can choose.

0010 On the other hand, in an extraction container where the bottom of the molded filter is not in contact with the bottom of the cup, It is difficult to effectively extract the substance to be extracted. The reason is that the bottom of the cup and the molded filter It is a double-structured extraction container with a gap at the bottom, which is similar to the conventional drip method. This is because problems arise and are difficult to extract. Therefore, before the extracted material swells, elongates, and expands upon contact with the poured hot water, This is because water can instantly pass through the molded filter while being subjected to water pressure. I don't like it.

[0011] The more space there is between the bottom of the cup and the bottom of the molded filter, the more effectively the material to be extracted can be extracted. Cannot be extracted. Synthetic fibers with stretchability that can be stretch-molded into the molded filter used in this invention. The sheet-like material is made of composites such as polyester, polypropylene, and polyethylene resins. If it is composed of synthetic fibers obtained from synthetic resin, long fibers or short fibers are considered. It's not something.

0012 In addition, polyester and polypropylene, polyester and low melting point polyester It may also be a heat-fused fiber such as a sheath-core or a multi-component fiber with a bimetallic structure. , if necessary, there is no restriction on the use of mixtures of these synthetic fibers. stomach. The above-mentioned sheet materials made of synthetic fibers include woven fabrics, knitted fabrics, non-woven fabrics, etc. Depending on the situation, multiple synthetic fibers may be mixed, and adhesives or heat-sealable fibers may be mixed. It may be the same.

[0013] In addition, the above-mentioned sheet-like material may include, but is not particularly limited to, the flange portion. By integral molding, it is stretch-molded into an almost cup shape and has the ability to maintain its shape. It is a synthetic fiber sheet-like material that has the ability to Naturally, consideration should be given from a food hygiene perspective. Needless to say, this is something that should be done. Furthermore, it is important that the molded filter used in the present invention has a flange. Ru.

[0014] That is, by integrally molding a sheet-like material into a cup shape, the molded filler obtained is The router is continuous from the bottom of the molded filter to the side, mouth, and flange. As a result, the fiber density and average basis weight increase, and the rigidity gradually increases. The fact that the molded filter used in the present invention has a flange allows it to retain its shape. Important for providing rigidity and handling. Because it has a flange, it is difficult to be bolted. When putting food in or pouring boiling water, it will not fall into the cup. Furthermore, It is easy to take out the filter after delivery.

[0015] Without the flange part, shape retention is poor and it tends to fall into the cup, making it difficult to form. This is not recommended as it may cause problems such as difficulty in removing the filter. The shape of the molded filter is large enough to be inserted into the cup used, and the bottom It is possible to come into contact with people. In other words, the diameter of the molded filter is smaller than the diameter of the cup. If the size is small and the depth is such that the bottom of the molded filter touches the bottom of the cup, then It can be big or small.

[0016] The molded filter used in the present invention has an average basis weight of 30 to 150 g/m ² at the bottom and side parts, so that the material to be extracted can be extracted effectively and a desirable effect can be obtained. In this way, it is possible to provide an extraction container in which a molded filter, which is molded in a shape that almost contacts the inner surface of the cup and has a flange portion, is inserted into the cup.

[0017]

【Example】

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described based on FIGS. 1-4.

[0018]

[Example 1] Polyester length that is crimped and formed into a sheet using only a hot embossing roll, has an average fineness of about 4 denier, a basis weight of 150 g/m ² , and has a breaking elongation of 200% or more when heated at 120°C. A fiber nonwoven fabric sheet was selected and used. Two metal plates with holes made to the same size as the diameter of the cup (1) were prepared. The nonwoven fabric sheet is firmly sandwiched between the two metal plates, and a convex mold approximately the same size as the cup (1) is heated to about 140°C, and the nonwoven fabric sheet sandwiched between the metal plates is pressed and molded. I used it as a filter.

[0019] Place the flat part of the obtained molded filter (2) between the metal plates into a paper cup. Adjust it to the dimensions of the flange (3) and handle (4) so that it will fit on the mouth. I cut it out (Figure 2). The resulting molded filter is most elongated at the bottom (7), then at the bottom of the sides. part (6) is stretched, and the side upper part (5) has relatively little stretch forming and flanges. The groove was formed continuously with almost no elongation. Therefore, in particular, The presence of the groove provided a molded filter with excellent shape retention.

[0020] When only the flange portion of the obtained molded filter was cut out and the average basis weight was measured, it was found to be 148 g/m ² . Similarly, the upper side surface was 100 g/m ² , the lower side surface was 60 g/m ² , and the bottom was 42 g/m ² . The obtained molded filter was inserted into the paper cup to create an extraction container.

[0021] Place 2g of canned high-grade black tea into the resulting extraction container and pour 150ml of boiling water. is. The tea leaves quickly grow and expand within almost the entire volume of the paper cup. At the same time, you can see with your own eyes the color of the tea begins to appear and it looks delicious. did it. 60 seconds after pouring boiling water, grab the handle of the molded filter and hold it still. By lifting the tea leaves from the cup, remove the tea leaves from the cup. I was able to throw it away along with the shaped filter. The resulting extract has a wonderful aroma and beauty. It was a delicious tea.

[0022]

[Example 2] Using the same nonwoven fabric sheet as in Example 1 except that the basis weight was 250 g/m ² , two metal plates with holes 4 mm smaller than the diameter of the cup (1) were prepared. The nonwoven fabric sheet was firmly sandwiched between the two metal plates, and a convex mold with a depth 10 mm smaller than the cup was heated to about 140°C and pressed into the nonwoven fabric sheet sandwiched between the metal plates. , a molded filter.

[0023] The flange portion (3) of the obtained molded filter (2) was cut to a size of 3 mm, and the handle portion (4) was cut to a size of 7 mm. When only the flange portion of the obtained molded filter was cut out and the average basis weight was measured, it was 247 g/m ² . Further, the upper side surface was 165 g/m ² , the lower side surface was 105 g/m ² , and the bottom was 88 g/m ² .

[0024] The obtained molded filter was inserted into the paper cup to create an extraction container. . Pour 2.5g of regular coffee powder into the extraction container and add 150ml of boiling water. I poured it. 90 seconds after pouring hot water, grab the handle of the molded filter. By gently lifting the cup, the coffee powder is removed from the cup and molded. I was able to throw it away with the filter.

[0025] The resulting extract has a wonderful aroma and delicious coffee without a powdery texture. It was hot.

[0026]

[Comparative example 1] As a comparative example, carefully tear open a portion of a commercially available black tea bag and extract the tea inside. Throw it away and replace it with 2g of the canned black tea you used above, and remove the torn part like the original bag. was sealed. Place the obtained tea bag in the same paper cup as in Example 1, Similarly, 150 ml of boiling water was poured.

[0027] Only a slight diffusion of black tea color can be seen, and after 60 seconds the above tea bag When I took out the tea, I could only get black tea with a pale color and little aroma. Well, it wasn't a delicious cup of tea. When I took out the tea leaves from the used bag and examined them, I found that they were still curled up. It is clear that there are many leaves that are close to I made it clear.

[0028]

[Effect of the idea]

The extraction container of the present invention has the following effects. 1) If you add the material to be extracted and pour boiling water over it, the material to be extracted will absorb enough of the hot water used. Because swelling, elongation, and expansion occur quickly within the large available capacity, It becomes difficult to pass through the filter, and effective extraction can be performed in a short time.

[0029] 2) Furthermore, the diameter is large, making it easy to pour in the extracted material and boiling water. Wear. 3) The internal volume of the cup can be used sufficiently with the filter still inside. 4) Separately place the material to be extracted in a sealed pouch, or use a spoon, stirring rod, etc. You can store the small items you need.

[0030] 5) Put a lid on it and it becomes a very compact container with a filter. 6) Furthermore, when pouring boiling water to extract, a spoon, stirring stick, etc. is sufficient. Can be stirred.
