Abstract

PURPOSE:To use a coffee can itself as an extracting vessel without opening the cover of the can by sandwiching the coffee can with a hot water injecting tank and a stand, forming an injecting port on the upper board of the can with the projection of the hot water injecting tank and forming fine holes on the bottom board of the can with the many needles of the stand. CONSTITUTION:Coffee powder 5 is packed and hermetically sealed in a coffee can 1 with volume ratio almost 30-50%. At first, a hot water injecting tank 8 is moved in a lower direction from a condition that the hot water injecting tank 8 is positioned in an upper direction and a stand 12 is positioned in a lower direction with being separated. Then, the stand 12 is moved in the upper direction and the coffee can 1 is sandwiched between the stand and tank. After that, a hot water injecting port 11 is formed on an upper board 3 of the can 1 by projection 9 of the hot water injecting tank 8. Many fine holes 14 are formed on a bottom board 4 of the can 1 by needles 13 of the stand 12. After that, the stand 12 moves downward and goes away in a horizontal direction and a coffee liquid receiving vessel 15 is arranged in the lower direction of the can 1. When hot water is put into the hot water injecting tank 8, this hot water is injected from an injecting port 10 into the can and the coffee is extracted and dripped from the fine holes 14 to the coffee liquid receiving vessel.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method and apparatus for brewing one can of coffee at a time without opening the top of the can, and a coffee can.

(Prior Art) A typical coffee extraction method is to open a can of coffee powder, take it out, add hot water to it, and filter it. Therefore, in businesses or places where people gathered, a filled coffee can with a content of 1200 g was opened, the coffee grounds were transferred from the coffee can to another brewing container, and hot water was added.

(Problem N to be Solved by the Invention) The conventional coffee extraction method described above has a problem in that it is necessary to open the coffee container and transfer the coffee powder inside to another extraction container.

In view of the above-mentioned problems with the conventional method, the present invention is a novel method that eliminates the trouble of transferring coffee powder from a can to another extraction container by using the coffee container itself as an extraction container without opening the lid of the coffee container. The object of the present invention is to provide a novel method for extracting coffee, as well as an apparatus for carrying out this method, and a novel method for making coffee for use in this new method.

(Means for Solving the Problems) In order to achieve the above object, the coffee extraction method of the present invention includes:
Using a coffee container filled with approximately 30% to 50% coffee powder by volume and sealed, a hot water injection tank with a sharp protrusion at the bottom with a hot water spout at the tip is placed above the coffee container. A pedestal with many thin, sharp needles on the top is placed below the coffee maker, and the coffee maker is sandwiched between the hot water injection tank and the pedestal, and the protrusion of the hot water injection tank connects the inlet to the upper slope of the can. pores are formed in the can bottom plate by the numerous needles on the pedestal, and hot water is poured into the can by pouring hot water into the hot water injection tank. It is characterized by receiving coffee liquid extracted from the pores.

In addition, the extraction device of the present invention has a volume ratio of approximately 30% to 50%.
A hot water pouring tank having a sharp protrusion at the bottom with a hot water spout at the tip, and a hot water injection tank that is movable up and down above the coffee powder. A hot water injection tank, a pedestal with a large number of thin sharp needles on the upper part, and a pedestal disposed below the coffee converter so as to be able to move up and down and in the horizontal direction; and a coffee liquid receiver disposed below.

Furthermore, the present invention is also characterized by a coffee container filled with approximately 30% to 50% coffee powder by volume and sealed.

(Example) Hereinafter, the present invention will be explained in detail by showing examples.

In the figure, 1 is a coffee container, which is made of the same material as known cans. This coffee can consists of a can body 2, a top plate 3, and a bottom plate 4, and unlike known cans, it does not require an easy-to-open structure such as a pull-top mechanism. This coffee can 1 is filled with approximately 30% to 50% coffee powder 5 by volume and is sealed. This coffee conversion is characterized by filling the coffee powder in an amount of approximately 50% or less, and if it is filled with more than approximately 50%, as will be described later, when pouring hot water, the coffee powder will be mixed with the hot water in the can. There is a fear that it will overflow outside, which is not desirable.

6 in the figure is a mounting table on which the coffee conversion 1 is placed and fixed;
It has a ring shape and has a space 7 that accommodates the vertical movement of the pedestal, which will be described later.

A hot water injection tank 8 is disposed above the coffee making 1. In the drawing, this hot water injection tank 8 is drawn to be about the same size as the coffee maker 1, but it is actually larger than the coffee maker 1. The bottom of the hot water injection tank 8 is provided with a sharp protrusion that protrudes downward facing the upper slope 3 of the coffee making 1,
A spout 10 for pouring hot water into the pouring tank 8 is formed at its tip. This hot water injection tank 8 is equipped to be able to move up and down, and when it moves down, the protrusion 9
A hot water inlet 11 is formed in the upper plate 3 of the coffee maker.

On the other hand, below the coffee maker 1, there is provided a pedestal 2 having a large number of thin, sharp needles 13 facing upward at its upper part. This pedestal 12 is arranged to be able to move up and down and to move in and out in the lateral direction, and when it moves up, it sandwiches the coffee making 1 between it and the hot water injection tank 8, and a large number of them are placed on the bottom plate 4 of the can 1. pores 14 are formed. After forming a large number of pores 14 in the can bottom plate 4 using the pedestal 120 and the needles 13, the pedestal 12 is moved downward and laterally withdrawn.

At the same time, a coffee liquid receiver 15 is arranged below the coffee converter 1 in place of the above-mentioned pedestal. Although this receptor 15 is also drawn small in the drawing, it is actually larger.

Now, in the state shown in the first diagram, the hot water injection tank 8 is connected to the coffee can 1.
The pedestal 12 is also located at a distance above the coffee can 1.

From this state, the hot water injection tank 8 is moved down and the pedestal 12 is moved upward, and the coffee can 1 is fixed between them. form. At the same time, a large number of pores 14 are formed in the bottom plate 4 of the can 1 by the needle 13 of the pedestal 12 (as shown in the second figure). The size of the pores 14 is preferably small enough that the coffee powder 5 does not pass through.

After that, when the pedestal 12 is moved down and exited laterally, the coffee liquid receiver 15 is placed below the can 1, and hot water is poured into the hot water injection tank 8, and this hot water is poured into the protrusion 9. It is injected into the can through the outlet 10. This hot water then extracts the coffee and is poured into the coffee liquid receiver through the pores 14 in the bottom plate 4 of the can 1 (as shown in the third figure).

<Effects of the Invention> As described above, according to the method, device, and coffee can of the present invention, the coffee can can be used as a coffee extraction container without opening the lid of the coffee can or taking out the coffee powder inside the can. It has the effect that it can be used to extract coffee, and has achieved the intended purpose.
