Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an improvement of a coffee pack in which coffee powder is enclosed in advance in a filter paper pack and hot water is prepared when necessary to enjoy a full-fledged cup of coffee easily. Regarding

[0002]

2. Description of the Related Art Conventionally, various types of simple coffee packs have been proposed in which roasted coffee beans are ground and sealed in a filter paper pack in an appropriate amount to extract one cup of coffee.

Among them, the mainstream of commercially available coffee packs is called a cassette type. As shown in FIG. 7, a short cylindrical coffee container 11 is integrally protruded from the bottom of a cup-shaped hot water pouring container 10 of a plastic molded product through an annular step, and the coffee container It has a structure in which coffee powder is enclosed on the bottom surface and the annular step portion and coffee powder is enclosed inside (Japanese Utility Model Publication No. 52-46630).

When this coffee pack is placed on a cup and hot water is poured into a hot water infusion container, one cup of coffee can be extracted.

This cassette type coffee pack has one
Although it is thrown away only once, another so-called cartridge type is configured such that the coffee storage portion is separated from the hot water infusion container and is separately configured as a cartridge, and only this cartridge portion is disposable. The cartridge has a structure in which a filter paper is attached to the bottom and the opening edge of the upper surface of a plate-shaped body of a plastic molded product having a hole in the bottom, and coffee powder is enclosed inside (Japanese Utility Model Publication No. 59-40910).

This cartridge is detachably fitted into the bottom opening of the hot water pouring container to assemble a coffee pack similar to the above cassette type. When the coffee is filled, only the cartridge is removed and replaced with a new one, and the hot water pouring container is repeatedly used. use.

[0007]

As described above, both the cassette type and the cartridge type have the advantages that the hot water filling container is a plastic molded product, is not deformed even when hot water is poured, is safe, and has a low manufacturing cost and a light weight. However, it has a weak point that it is easily damaged during transportation. For this reason, the hot water infusion container must be housed in the outer case when shipped from the factory, but the entire coffee pack or cartridge part must be air-tightly packed with a gas barrier film to prevent the taste of coffee powder from being oxidized by oxidation. Since the deterioration cannot be prevented, in the case of the conventional product, as shown in FIG. 7, after all, as shown in FIG. 7, a protective package 13 for preventing damage must be provided on top of a film package 12 for preventing oxidation. In addition, since double packaging is required, the whole product is bulky and inconvenient to carry, and the cost for packaging increases the product price.

The present invention solves the above-mentioned problems of the prior art. While completely preventing the oxidation of coffee powder, the packaging is simplified and the cost is reduced, and the entire product is made compact and robust and portable. The purpose is to make it convenient.

[0009]

According to the present invention, a conventional coffee pack is put in a can and sealed. However, the can is used not only as a sealed container but also as a hot water filling container.

According to the first aspect of the present invention, the coffee powder is enclosed between the upper and lower two filter papers to form a disk-shaped coffee pack, and the upper and lower surfaces of the can containing the coffee pack are for opening respectively. A weakening line and a handle are provided, and the weakening line on the lower surface is formed so that the outer periphery of the coffee pack fits into the lower opening when the can is opened.

According to the second aspect of the present invention, the coffee powder is enclosed between the upper and lower two filter papers to form a disk-shaped coffee pack, and a plurality of the coffee packs are housed in a can. Each has a weakening line and a handle for opening,
The weakening line on the upper surface is formed larger than the coffee pack in the can when the can is opened, and the weakening line on the lower surface is formed such that the outer periphery of the coffee pack fits into the lower opening when the can is opened.

[0012]

In both the invention of claim 1 and the invention of claim 2, at the time of use, the handle is pulled to open both the upper and lower surfaces of the can along the weakening line. After the opening, in the invention of claim 1, the coffee in the can is opened. The pack is pushed into the lower opening of the can to fit the outer periphery of the coffee pack, and in this state, the can is placed on the cup and hot water is poured from the upper opening to extract the coffee.

In the invention of claim 2, first, one coffee pack in the can is left from the top opening and the other is taken out, and the remaining coffee pack is fitted into the bottom opening and used as in the invention of claim 1. To do.

[0014]

Embodiments of the present invention will now be described with reference to the drawings.

P is the same coffee pack as the conventional one, and the first specific example thereof is a plastic molded dish 1 having fan-shaped extraction holes radially opened on the bottom surface as shown in FIGS.
Attach filter papers 2 and 3 to the bottom and top opening edges, respectively.
An appropriate amount of coffee powder is enclosed inside.

The second specific example of the coffee pack P is the sixth example.
As shown in the drawing, the dish-like body 4 is formed by a special plastic filter paper, coffee powder is contained inside, and a circular filter paper 5 is adhered and sealed to the opening edge of the dish-like body 4. As the plastic filter paper, for example, a polyethylene terephthalate non-woven fabric coated with sorbitan fatty acid ester as a hydrophilic agent to impart water permeability is suitable. When this material is formed into a dish by pressing, it has the property that it does not lose its shape even when hot water is poured, and it is well water permeable.

Each of the coffee packs P is a plate-shaped body 1 or 4
It is advisable to taper the cylindrical surface so that the diameter becomes slightly smaller toward the bottom.

Next, 3 to 5 of these coffee packs P,
It is housed in a cylindrical can 6 and sealed. The volume of the can 6 is preferably about 1.5 coffee cups. The material of the can 6 is a metal such as steel or aluminum, and annular weakening lines 7 are formed on both upper and lower surfaces of the can 6, and the handles 8 and 8 are fastened. When sealed in a can, degas and replace with nitrogen.

Here, the weakening line on the upper surface is larger than the maximum diameter of the coffee pack P, and the weakening line on the lower surface is formed in such a size that the outer periphery of the cylindrical portion of the coffee pack P fits. In the figure, R represents the diameter of the weakening line on the upper surface, and r represents the diameter of the weakening line on the lower surface. Therefore, the following inequality holds between R and r and the maximum diameter L of the coffee pack P.

R <L <R When the weakening line 7 on the upper surface is interrupted as shown in FIG.
When opened, the opening 9 remains without being completely separated from the can 6, so that this opening 9 can be used as a handle and the hot can 6 can be used.
It is convenient because you do not have to touch the.

When using, pull the handles 8, 8 to pull out the can 6.
Both upper and lower surfaces of the coffee machine are opened along the weakening line 7, one coffee pack P is left inside and the other is taken out once.

Then, as shown in FIG. 3, the upper portion of the coffee pack P remaining in the can is pushed with a fingertip to be pushed out from the bottom of the can 6, and the cylindrical portion thereof is tightly fitted into the lower surface opening. Place the can 6 on top of it and pour boiling water into the can 6 through the top opening.

The hot water reaches the coffee powder from the filter paper 3 or 5 at the top of the coffee pack P to extract the coffee, and the coffee gradually drops from the filter paper 2 or the plate 4 at the bottom into the cup.

When one cup of coffee has been added, the used coffee pack P is pushed back into the can 6 and removed.
Replace with a new coffee pack.

When only one coffee pack P is sealed in the can 6, it is not necessary to take out the coffee pack before use, so the size of the upper opening of the can 6 may be arbitrary.

The shape of the can 6 is not limited to a cylindrical shape, but may be a rectangular tube shape.

[0027]

In summary, according to the present invention, the coffee pack P in which the coffee powder is enclosed between the filter papers is housed in the can 6 and hermetically sealed, so that the freshness of the coffee powder is maintained for a long time and the taste is good, and the conventional one is The packaging with the gas barrier film can be omitted.

Further, when the weakening lines are provided on both upper and lower surfaces of the can 6 and the can is used as a conventional hot water pouring container, it is not necessary to separately prepare a dedicated hot water pouring container, and since the can is tough, it is protected. The effect is that the packaging for it can be omitted and it is also convenient to carry.
