Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable regular coffee set for use at home or for outdoor activities.

[Conventional technology]

Typical portable regular coffee sets of this type are shown in Figure 3 A and B [for example,
The one shown in Japanese Utility Model Application Publication No. 59-13230 and shown in FIG. 4 is known.

The items shown in Figure 3 A and B are coffee cups 5
Freshly ground coffee powder is stored in a straining bag 52 connected to the center member of a cardboard support member 51 that can be attached in an arch shape to the peripheral edge of the opening of the paperboard, and this straining bag 52 can be easily opened. After sealing in the state,
This is folded and sealed with an aluminum bag 53. This is because the coffee powder and the paper strainer bag 52 are in direct contact during storage, so the oil content of the coffee powder easily seeps into the strainer bag 52, resulting in poor moisture absorption and flavor loss. The rate of extraction of the soluble components contained therein may be slowed down, making the coffee taste astringent and bitter. Furthermore, each coffee cup 50 must be prepared each time the coffee is poured, which is particularly inconvenient when used for outdoor activities such as hiking.

Furthermore, in the case shown in FIG. 4, freshly ground coffee powder is sealed in a strainer bag 55 and then sealed in an aluminum bag (not shown).

The general method of using this is to put the strainer bag 55 taken out from the aluminum bag into the coffee cup 56,
After pouring hot water into the pouring part 55a of this straining bag 55,
This is a method of extracting soluble components by vibrating the coffee powder up and down, but in this case, the temperature of the hot water that comes into contact with the coffee powder decreases due to heat exchange with the surrounding coffee cup 56. This has a negative effect on the expansion of the coffee tissue, making it impossible to sufficiently extract the soluble components of flavor and aroma.

Therefore, conventionally, as shown in Japanese Utility Model Application Publication No. 52-91888, for example, a bottomed cylindrical drip cup, a sealed bag for coffee powder, and a strainer bag were separately placed inside a cup with a lid. A hole is made in the lid along the cutout line of the lid, the lower part of the drip cup is fitted into the hole, a straining bag is attached to the drip cup, and coffee powder is poured into the straining bag to extract coffee. was.

[The problem that the idea aims to solve]

The conventional device configured as described above is effective in avoiding the problems of oil seepage into the strainer bag and a drop in water temperature, but it is difficult to attach the drip cup to the lid or attach it to the drip cup. Attaching the strainer bag was troublesome.

Also, if a large amount of hot water is poured and a large amount of the extract that passes through the strainer bag is collected in the drip cup, the coffee powder that adhered to the inside of the strainer bag and formed a filtration layer will be removed from the inside of the strainer bag. If the filter layer peels off and the filter layer is destroyed, the poured hot water may pass through the strainer bag without making sufficient contact with the coffee components, resulting in insufficient extraction. However, there remains the problem that the degree of extraction of coffee components tends to vary depending on the extraction method.

Furthermore, if the enclosing cup used as a portable set is made small so that each person or a small number of people can use it as a coffee cup, the amount of coffee powder will inevitably be small, so it is necessary to use a strainer bag. The thickness of the coffee powder layer inside becomes thinner. At this time, even if a small amount of hot water is poured, the coffee powder is pushed away by the water pressure, leaving almost no residue at the point where the hot water is poured, resulting in the same problem as mentioned above, where the hot water is filtered without coming into contact with the coffee powder. Also, there was a problem in that foaming due to swelling of the coffee powder was difficult to occur, and as a result, the temperature of the structure of the coffee powder in contact with hot water rapidly decreased, resulting in a decrease in extraction efficiency.

In order to make it possible to easily and deliciously drink fresh coffee with a high aroma, this invention not only makes it easy to set up the equipment, but also makes the brewing process efficient and efficient even in a small set. The purpose is to obtain a portable regular coffee set that is easy to use, has a simple structure as a whole, and can be provided at low cost.

[Means to solve the problem]

The portable regular coffee set according to the present invention is characterized in that a coffee bag with sealed coffee powder and a strainer bag separate from the coffee bag are placed inside a cup equipped with a lid member. In addition to being packaged, it also has the configurations described in [A] to [C] below.

[B] The straining bag is integrally constructed with a bottomless cylindrical member that holds the upper edge of the bag in an open position.

[B] The lid member is formed into a ring shape and includes a fitting portion that is detachably attached to the peripheral edge of the opening of the cup and a through hole having a smaller diameter than the upper opening of the cup.

[C] The cylindrical member has an upper end opening with a smaller diameter than the opening of the cup, and is capable of being held in position with the lower end of the cylindrical member fitted into the through hole of the lid member. , the dimensions of the fitting portion with respect to the through hole are set.

[Function] As described above, since the freshly ground coffee powder is sealed separately from the strainer bag, it is possible to avoid a decrease in the extraction speed caused by the oil content of the coffee powder adhering to the strainer bag. .

Moreover, since the straining bag can be attached to the cup in an open position floating above the bottom surface of the cup, drips can be easily placed in the straining bag without having to support each straining bag with one's hand as in the conventional case.

The cylindrical member that holds the upper edge of the straining bag has a bottomless shape that does not have a bottom surface that faces the bottom surface of the straining bag, so the extract that has passed through the straining bag drips into the cup as it is. In other words, even if a large amount of hot water is poured, the liquid will not accumulate on the outside of the strainer bag, and the liquid will peel off the filtration layer of coffee powder inside the strainer bag. That can be avoided.

The lid member is formed with a through-hole having a smaller diameter than the upper end opening of the cup, and a cylindrical member having an upper end opening smaller in diameter than the cup opening is fitted into this through-hole to attach the straining bag. The area in plan view can be made smaller than when the opening is provided over the entire surface of the upper opening of the cup. In other words, even if the total amount of coffee powder is small, the thickness of the coffee powder layer in the straining bag can be made relatively thick. Therefore,
By simply pouring a small amount of hot water, you can prevent the coffee powder layer from being pushed away by water pressure to the extent that the inner surface of the strainer bag is exposed, and as a result, the structure of the coffee powder and the poured hot water can be Good contact can be achieved and generation of bubbles can be promoted.

Since the straining bag is integrated with the cylindrical member in advance and a through hole is formed in the lid member in advance, there is no need to drill holes in the lid member or attach the straining bag to the cylindrical member.

[Effect of idea]

(b) Due to the effects of ~ above, the tools for pouring coffee using the drip method are prepared in one cup as described above, so as long as you prepare hot water, you can easily enjoy fresh coffee with a high aroma. I was able to drink it quickly and deliciously.

(b) Due to the above-mentioned action, the influence of the extraction method and the size of the set is small, and the state in which the filtration layer formed by the adhesion of coffee powder is maintained evenly over a wide area in the strainer bag, and the coffee powder is poured. It has become possible to efficiently and efficiently extract high-quality coffee by making good contact between hot water and the structure of coffee powder and by making good foam generation.

(c) Due to the above-mentioned action, there is an advantage that the setting of the equipment can be done extremely easily.
