Japanese Patent Laid-Open No. 2003-190019

An object of the present invention is to provide an extraction container capable of reducing the time required for extracting the extract while improving the quality of the extract.

An extraction container according to an aspect of the present invention comprises:
A container body having an injection side opening and a dispensing side opening;
A filter support formed to protrude from the inner surface of the container body;
An extraction side filter that is shaped to project toward the extraction side opening and is supported and fixed to the filter support;
An accommodating portion that is formed by an inner surface and a bottom surface of the extraction-side filter and accommodates a desired extraction target;
An injection side filter fixed to a region of the extraction side filter supported by the filter support part so as to cover the extraction object accommodated in the accommodation part.

According to the extraction container of the present invention, the time required for extracting the extract can be shortened while improving the quality of the extract.

It is the perspective view, top view, and longitudinal cross-sectional view which show the structure of the extraction container by embodiment of this invention. It is a longitudinal cross-sectional view which shows the mode at the time of extracting a coffee drink. It is a top view which shows the structure of the extraction container of a comparative example.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a configuration of an extraction container 10 according to an embodiment of the present invention. Among these, Fig.1 (a) shows the perspective view of the extraction container 10, FIG.1 (b) shows the top view at the time of visually confirming the extraction container 10, and FIG.1 (c) is an extraction container. FIG. 1D is a longitudinal sectional view taken along the line AA ′ in FIG. 1A. FIG.

The extraction container 10 includes, for example, a container body 20 in which a paper material such as cardboard is formed into a cylindrical shape, an upper opening 30 for pouring hot water, and a lower opening for pouring an extracted coffee beverage into a coffee cup. 40. Further, the extraction container 10 is formed in a trapezoidal shape so that the diameter decreases from the upper opening 30 toward the lower opening 40.

In the vicinity of the lower part of the inner side surface of the container body 20, a filter support 20 </ b> A is formed in an annular shape so as to protrude from the inner side surface of the container body 20.

The lower filter 50 is manufactured using, for example, a non-woven fabric, and the upper portion of the filter support portion 20A and the peripheral portion of the lower surface of the lower filter 50 are formed so that the portion excluding the peripheral portion protrudes downward. By being fixed, the container body 20 is attached.

In this case, the distance H10 from the filter support 20A to the bottom of the lower filter 50 is formed to be shorter than the distance H20 from the filter support 20A to the lower end of the container body 20.

Incidentally, by forming the lower filter 50 so as to project downward, a storage part 60 is formed, and the coffee powder 70 is stored in the storage part 60.

For the purpose of steaming coffee powder, the peripheral portion of the lower surface of the upper filter 80 is fixed to the peripheral portion of the upper surface of the lower filter 50 so as to cover the coffee powder 70 stored in the storage portion 60. Thus, the upper filter 80 is attached to the lower filter 50.

Here, FIG. 2 shows a state in which the coffee container is extracted by placing the extraction container 10 on a coffee cup (not shown) and pouring hot water from above the extraction container 10.

As shown in FIG. 2A, when hot water is poured into the upper opening 30 from above the extraction container 10, the hot water permeates through the upper filter 80 into the accommodating portion 60. Thereby, hot water is stored in the storage unit 60, and the components contained in the coffee powder 70 are eluted into the hot water stored in the storage unit 60, whereby an extract is generated.

At the timing when hot water starts to be poured into the upper opening 30, the extract falls down from the entire bottom surface of the lower filter 50 so that the extract is poured into the coffee cup.

Thereafter, as shown in FIG. 2 (b), the central portion of the lower filter 50 hangs downward due to the weight of the hot water stored in the accommodating portion 60, and the extract liquid is drawn from the central portion of the lower filter 50. Fall down. Thus, a coffee drink is produced | generated when an extract is poured into a coffee cup.

Here, as a comparative example, FIG. 3 shows a configuration of an extraction container 100 in which ribs 120 for supporting the lower filter 110 are formed integrally with the container body 130 and are formed radially below the lower filter 110. . The extraction container 100 is made of a synthetic resin such as plastic.

In the case of the extraction container 100 of this comparative example, when extracting the coffee beverage, the extract falls downwardly from the region 140 where the lower filter 110 is exposed on the bottom surface of the lower filter 110.

Therefore, in the case of the extraction container 100 of this comparative example, the area where the extract can be poured out of the bottom surface of the lower filter 110 is small, which makes the lower filter 110 easily clogged. As a result, there is a problem that the time required for extraction becomes long.

On the other hand, in the case of the extraction container 10 according to the present embodiment, the extraction liquid can be poured out from the entire bottom surface of the lower filter 50, and as a result, the time required for extraction can be shortened. At the same time, the quality of the extract can be improved.

Thus, according to the present embodiment, it is possible to shorten the time required for extracting the coffee beverage while improving the quality of the extracted coffee beverage.

By the way, in the case of the extraction container 10 according to the present embodiment, the distance H10 from the filter support 20A to the bottom of the lower filter 50 is greater than the distance H20 from the filter support 20A to the lower end of the container body 20. It is formed to be shorter.

Thus, for example, when the extraction containers 10 are stacked in the vertical direction in order to facilitate transport for the purpose of distributing to the market, the upper filter 80 of the extraction container 10 positioned on the lower side and the extraction positioned on the upper side. Contact with the lower filter 50 of the container 10 can be prevented. Therefore, the lower filter 50 and the upper filter 80 can be prevented from being damaged, and the reliability of the extraction container 10 can be improved.

Note that the above-described embodiment is an example, and does not limit the present invention. For example, as the extraction object stored in the storage unit 60, other various extraction objects such as tea leaves may be stored in the storage unit 60 instead of the coffee powder 70.

In the above embodiment, the case where the container body 20 is applied as the container body has been described. However, the upper opening 30 as the injection side opening and the lower opening 40 as the dispensing side opening are provided. Various other container bodies may be applied.

In the above-described embodiment, the case where the filter support portion 20A is applied as the filter support portion has been described. However, various other filter support portions formed so as to protrude from the inner surface of the container body 20 are described. May be applied.

In the above-described embodiment, the case where the lower filter 50 is applied as the extraction filter has been described. However, the lower filter 50 is shaped so as to project toward the lower opening 40 and is supported by the filter support 20A. It is also possible to apply other various extraction side filters that are fixed.

Moreover, in the above-mentioned embodiment, although the case where the accommodating part 60 was applied was described as an accommodating part, it formed with the inner surface and bottom face of the lower filter 50, and accommodates a desired extraction target. You may make it apply a various accommodating part.

Further, in the above-described embodiment, the case where the upper filter 80 is applied as the injection filter has been described. However, the coffee powder stored in the storage unit 60 is covered with the filter of the lower filter 50. You may make it apply the other various injection | pouring side filters fixed to the area | region currently supported by 20 A of support parts.

In the above-described embodiment, the case where the lower filter 50 is applied as the extraction filter has been described. However, the distance from the filter support 20A to the extraction end of the lower filter 50 is the filter. What is necessary is just to form so that it may become shorter than the distance from 20 A of support parts to the extraction side edge part of the container main body 20. FIG.

In the above-described embodiment, the case where the container body 20 is applied as the container body has been described. However, the container body 20 is formed in an annular shape so that the diameter of the upper opening 30 is longer than the diameter of the lower opening 40. What is necessary is just to form.
