Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a container in which a container filled with coffee powder and a filter for extracting the coffee liquid by brewing the coffee are integrated. Since it is heavy, it can be stored and transferred without being bulky, and the extractables such as coffee powder have good storability, and the liquid discharged from the filter also flows out well. It relates to an extractor that makes it possible to quickly put in a drip coffee with a good taste.

[0002]

[Prior art and problems]

 Various types of drip coffee extractors have been proposed in the past, but in recent years, one cup of compound coffee (regular coffee) has been put inside a filter paper. A disposable extractor (dripper) that is packed in a simple container that has been installed, and when the container is opened, hot water is poured into the container to drip the coffee extract into the cup. ) Has become widely used.

However, in the conventional device, a plurality of cassette type extractors are generally stacked and housed in one common exterior package (bag or container) for transportation, storage and sale. Once this is opened, the package and extractor have almost no airtightness, so the aromatic component of coffee volatilizes or deteriorates over time, leading to poor storage stability. is there. In other words, it is best to use fresh coffee in order to put authentic drip coffee with excellent taste and fragrance, but if you open the conventional product once, It was not possible to put in a delicious coffee, because the heat was absorbed and changed in quality due to oxidation, and the volatile aromatic components escaped in the remaining unused portion.

In addition, in the conventional type, when hot water is poured, the heat and the weight of about 150 cc cause the paper in the container to sag at the bottom and adhere to the inner surface of the bottom plate, resulting in clogging and the like. The extract could not be promptly ejected from the paper.

[0005]

[The purpose of the device]

 The present invention does not impair the stackability of the above-mentioned conventional ones, and it is possible to save a small amount of residual oxygen or inert gas in the coffee filling portion when storing after opening the exterior and interior packages. The airtight structure prevents the aromatic components of coffee from volatilizing and deteriorating due to oxidative moisture absorption, and also prevents the filter from adhering to the inner surface of the bottom plate during extraction of coffee liquid. It proposes a simple beverage extractor that allows the extract to flow out quickly.

[0006]

[Means for solving the problem]

 In order to achieve the above object, the extractor of the present invention is integrally formed with a main body having a gas barrier property and having a tubular cross-section, and is inclined downward and has a gas barrier seal at the center. A bottom plate having a liquid drop lower port with a lid attached, a rib-shaped projection is provided on the inner surface of the bottom plate, and a liquid outflow groove connected to the liquid drop lower port is provided, and a bottom slack supported on the projection is provided. A filter element that is designed to prevent this is provided, and a step portion that extends inward and is continuous in the circumferential direction is provided on the intermediate wall of the main body, and a gas barrier top sheet having a pull tab is provided on the step portion. It is characterized in that it is adhered and a predetermined amount of the substance to be extracted is enclosed between the top sheet and the filter element.

[0007]

【Example】

 Next, an example of an embodiment of the present invention will be specifically described with reference to the drawings.

1 to 4 show an embodiment of the present invention, FIGS. 1 and 2 are perspective views when opened, FIG. 3 is a vertical cross-sectional view of a container body, and FIG. 4 is a partial top sheet. FIG. 3 is a plan view of the container body shown in a broken manner.

In the drawings, reference numeral 1 is, for example, a synthetic resin cylindrical container body forming a hot water storage portion formed by means such as injection or pressure molding, and is opened so that the upper surface is slightly widened, A curl portion 2 which also functions as a reinforcement is formed on the outer periphery of the opening. The intermediate wall of the container body 1 is formed with a step portion 3 which extends inward and is continuous in the circumferential direction, and a bottom plate 4 which is continuous with the step portion and integrally formed with the body, and which is inclined downward. Are integrally formed. At the lowermost end of the bottom plate 4, there is provided a cylindrical small-diameter extraction droplet lower port 5.

The container body can be made, for example, of a general-purpose synthetic resin material such as PE, PS, and PP, but it is necessary to form it using a base material having a good gas barrier property. As a substrate having such a gas barrier property, for example, as shown in the cross-sectional view of FIG. 5, a PVDC film or a PVA film or a coextruded film thereof having a good gas barrier property is used as the central layer 21, and a HIPS film or A three-layer laminating material with a PP film as the surface layer 22 or a material obtained by coating or laminating PVDC or PVA as described above on one or both sides of an appropriate base film may also be used. Of course, in some cases, the container body may be formed by using a synthetic resin material such as PE, PS, HIPS, and PP having a thickness of 200 to 1000 μ alone. When the container body is formed of the base material having such a configuration, the permeation of gas from the side surface of the body can be suppressed extremely low.

By the way, at the root of the bottom plate 4 of the container body, for example, a peripheral portion of a paper filter element 6 made of pulp alone or a mixture of plastic and pulp is fixed. This filter element 6 is stretched on a rib-shaped protrusion 10 formed on the inner surface of the bottom plate 4 and is supported so as not to sag at the bottom. As shown in FIG. 6, a slight gap 12 may be provided between the two.

As shown by reference numeral 8, the upper surface of the filter element 6 is filled with a certain amount (one cup) of ground coffee which has been ground, and a step portion formed on the intermediate wall portion of the main body 1. A gas barrier top sheet 7 having a pull tab on top of 3 is fixed in a peelable manner. This gas barrier top sheet is, for example, a composite paper material in which a metal foil or a resin film is adhered to paper and cut into a shape and size that match the inner circumference of the stepped portion of the container body 1 and its peripheral edge. The part is fixed with heat seal or ultrasonic seal, or other adhesive means. Reference numeral 9 denotes a seal lid detachably attached to the mouth end of the extraction liquid droplet lower mouth 5 with an adhesive, and a pull tab is provided at one end thereof. It is preferable that this seal lid is made of a sheet material having a gas barrier property like the above-mentioned top sheet so that the inside of the coffee filling portion can be sealed. At the time of sealing, an inert gas such as nitrogen gas or carbon dioxide gas may be enclosed in the coffee filling portion. Of course, there is no problem even if the filling section is vacuumed.

By the way, the rib-shaped projections or irregularities formed on the inner surface of the bottom of the container body 1 shown in FIG. 3 support the filter element 6 from below and cause the filter element to sag under the heat and weight of the hot water. While having the function of preventing the above and simultaneously forming the liquid outflow guide groove 11 between the rib-shaped projections, it has a function of reinforcing the bottom plate itself. It should be noted that the extraction liquid drop lower opening need not be flat as shown in the present embodiment, and may be a tube-shaped projection below the bottom.

[0014]

[Action]

 Next, the function and effect of the extractor of the present invention having the above-described structure will be described. After the outer package is opened, the filter element 6 and the gas barrier top sheet of the present invention can be used even if the container of the present invention is left naked. The blending coffee is filled between it and the container 7, and the dripping port 5 at the bottom of the container is hermetically sealed with a seal lid 9 or the like. The freshness can be maintained for a long time without escaping from the side surface or the upper and lower parts of the container and deterioration of the coffee powder due to oxidation or moisture absorption. Moreover, since the filter element is protected by the bottom member of the container, damage is prevented, and it is easy to handle and durable. Therefore, it is not necessary to separately store this extractor in a sealed case for storage.

In use, as shown in FIGS. 1 and 2, the top sheet 7 and the seal lid 9 are peeled off, and then the step portion 3 is supported on the upper edge of the coffee cup. Then, the container body 1 is placed. Next, pour a cup of hot water (about 150 cc) into the hot water storage part of the container 1 from the exposed coffee powder 8. The coffee extract permeates the filter element 6 and leaches into the bottom 4 of the container. The extract leached to the bottom flows down along the bottom and flows into the cup through the dropping port 5.

[0016]

[Effect of the device]

 As described above, according to the present invention, the main body of the container is formed of the gas barrier material, and the upper and lower surfaces of the coffee filling portion are hermetically closed by the gas barrier top sheet and the seal lid. In particular, the filter element supported by the container body tends to sag slightly when pouring hot water due to the heat and weight, but since the rib-shaped protrusions are provided on the inner surface of the bottom plate, Supports the filter element from the bottom, prevents the filter element from sagging downward, prevents the filter element from sticking to the bottom plate, and allows the extraction liquid to flow out quickly. -You can quickly get your heels. Further, the irregularities and ribs also have the effect of reinforcing the bottom plate.

Further, since the top sheet is attached to the intermediate wall portion of the container body, there is an effect that the residual oxygen amount or the inert gas amount in the filled portion of the substance to be extracted (such as coffee) can be small. Therefore, the amount of oxygen suction and the amount of inert gas to be filled when evacuating the filling part of the extract are very small, so the work is easy and the cost is low, and the extract is stable. Is excellent and does not deteriorate over a long period of time. Moreover, since an appropriate number of containers can be stacked on top of the container, handling such as storage and transfer is easy, and the package for the exterior can be small.

It should be noted that in the examples, the substance to be extracted is limited to coffee, but black tea and green tea can also be used in the same manner.
