Description

[Detailed explanation of the idea] [Purpose of invention]

(Field of Industrial Application) This invention relates to a coffee cartridge used in a drip coffee brewer. (Prior Art) Commercial drip coffee brewers used in cafes, restaurants, and other eateries need to brew a large amount of coffee at one time. It was extremely uneconomical to use a bag-shaped paper filter containing ground flour. Therefore, put the required amount of ground coffee into an extractor equipped with a large strainer bag, and after brewing, take out and throw away the grounds each time.Especially, strainer bags are used to prevent residual coffee grounds from oxidizing. It was customary to soak it in clean water or wash it in preparation for the next extraction. (Problem to be solved by the invention) As described above, when using a drip coffee brewer, the post-processing of the grounds is troublesome as described above, and if handled incorrectly, Because it stains the surroundings and hands, it causes a decrease in work efficiency, especially in commercial use, and
If the strainer bag is reused with the coffee grounds still oxidized, there is a problem that the flavor of the next brewed coffee will be spoiled. This had become an issue. (Purpose of the invention) This invention was made in order to solve the above problems, and it is possible to extract coffee using a drip coffee brewer without requiring a large storage space. To provide a coffee cartridge that is easy to handle before extraction, and also allows easy setting of ground coffee powder and cleaning up of the ground coffee powder during extraction.

[Structure of the idea]

(Means for Solving the Problem) The coffee cartridge for drip extraction according to this invention is mainly composed of a flat ring body having openings on the upper and lower surfaces, and the openings on both the upper and lower sides of the main body are made of a water-permeable membrane material and a substantially cone. The problem is solved by having a structure in which an appropriate amount of ground coffee is stored inside a main body of a cartridge, which is closed with a filtration material that is folded in a shapeless and expandable manner, and is blocked by the water-permeable membrane material and the folded filtration material. It is intended as a means to solve the problem. In the coffee cartridge according to this invention, the filter medium is a foldable thin-walled so-called paper filter or cross filter, and the water-permeable membrane material is the same as the filter medium. However, if possible, one with low air permeability is preferable. Furthermore, the main body shape of the cartridge is preferably a circular shape with a small height dimension, considering the case where this coffee cartridge is set in an existing coffee brewer. (Function) Next, the function of the coffee cartridge according to this invention will be explained. When storing this coffee cartridge in a cupboard, etc., the cartridge itself will be handled in its own size, so if you stack it,
The storage space will be small. Then, the coffee cartridge is set above the pot of the drip coffee brewer with the filter material facing downward, and hot water is dripped onto the water-permeable membrane material. During this time as well, since the filter medium is folded so that it can be expanded, its handling becomes very easy. The hot water that passes through the water-permeable membrane material and reaches the main body of the cartridge permeates the ground coffee, expands the ground coffee and extracts coffee liquid, and the extracted coffee liquid is filtered through the filter material. It collects in the pot. During this extraction process, when hot water permeates into the ground coffee, its weight increases, so the filter material, which was initially folded, gradually unfolds into a cone-like shape, which prevents the coffee grounds from foaming and prevents the coffee from forming. There is no possibility that the water-permeable membrane material or this filter material will be torn due to the expansion of the ground powder. The extracted coffee extract then drips into the pot through the center of this approximately cone-shaped filter medium. Once the coffee has finished brewing, remove the empty coffee cartridge from the coffee brewer and throw it away. (Example) Hereinafter, an example of the coffee cartridge according to this invention will be described based on the drawings. 1 to 3 show an embodiment of the coffee cartridge according to this invention. The coffee cartridge 1 shown in the figure has a cartridge main body 2 which is a circular ring with a small height dimension, and an upper opening 2a of the cartridge main body 2.
is closed with a water-permeable paper filter (water-permeable membrane material) 3, and a substantially cone-shaped paper filter (filtering material) 4 is attached to the lower opening 2b. Inside the cartridge main body 2 which is thus closed, a required amount of ground coffee powder 5 which has been ground to suit drip extraction is accommodated. Paper filter 4 used in this example
is in a folded state before the coffee cartridge 1 is set in the drip coffee brewer, and is packaged in such a way that it unfolds into a substantially cone shape during the process of brewing coffee. . In other words, the size (capacity) of this coffee cartridge 1 is substantially the same as the size of the main cartridge 2, and when stored in a cupboard or the like, it can be stored in a small space by stacking it. It is something that can be done.
Furthermore, it is easy to handle before setting it in a coffee boiler, and the ground coffee powder 5 can be sufficiently expanded during the process of extracting coffee. Next, the procedure for brewing coffee using the coffee cartridge 1 will be explained using FIG. 4. The coffee boiler 10 used here includes a hot water pouring nozzle 12 provided at the top of the boiler main body 11, a cartridge holder support portion 13 provided near the top of the boiler main body 11, and a cartridge holder support portion 13 provided near the top of the boiler main body 11. A substantially cone-shaped cartridge holder 14 removably installed on the support part 13 of the holder, a pot holder 15 provided at the lower end of the boiler main body 11, a hot water tank (not shown), and a pot holder 15 built into the pot holder 15. It is equipped with a heater unit and a feeding means also built into the pot mounting table 15, and the heater unit has the function of heating the hot water in the hot water tank and keeping the coffee liquid collected in the pot P warm. , In addition, hot water for coffee extraction is supplied to the cartridge holder 1 through a pipe 16 built into the boiler body 11.
The molten metal is automatically fed from above 4 to a pouring nozzle 12 opposed to the molten metal. When brewing coffee, the coffee cartridge 1 is first held in the cartridge holder 14 of the boiler main body 11, and the cartridge holder 14 is attached to the support part 13 of the cartridge holder. During this time, the paper filter 4 of the coffee cartridge 1 remains folded, making its handling very easy. Next, the hot water from the hot water tank is heated by the heater unit, and the boiled water is sent to the pouring nozzle 12 through the pipe 16.
From this hot water pouring nozzle 12 to the coffee cartridge 1
Dripping of boiling water begins. The hot water dripped into coffee cartridge 1 is
After passing through the paper filter 3, the cartridge main body 2
It penetrates into the coffee grounds 5 in the main body 2, expands the coffee grounds 5, and begins extraction of coffee liquid. At this time, as the ground coffee powder 5 expands and its weight increases, the paper filter 4, which had been folded initially,
gradually opens and becomes approximately cone-shaped along the cartridge holder 14, so that the coffee grounds 5 expand,
Foaming will not be hindered, and the paper filters 3 and 4 will not be torn due to the expansion of the ground coffee powder 5. The coffee liquid extracted by the hot water passing through the coffee grounds 5 is absorbed into the coffee through hole 14a formed at the lower end of the cartridge holder 14.
It flows out and accumulates in the pot P placed on the pot mounting table 15. After the coffee has been extracted, the cartridge holder 14 is removed from the support part 13 of the cartridge holder, and the coffee cartridge 1 is discarded while leaving the coffee grounds inside the cartridge main body 2. In the embodiments described above, the paper filters 3 and 4 are used as the water-permeable membrane material and the filtration material, respectively, but the invention is not limited to this. It is also possible to use cross filters for each.

[Effect of the idea]

As explained above, the coffee cartridge according to this invention adopts a format that stores the required amount of ground coffee for drip extraction, and uses a water-permeable membrane material that blocks the upper and lower openings and a filter material to store the ground coffee. Since it has a closed structure, extraction cartridges of various sizes can be provided for both commercial and home use. Therefore, for example, in the case of commercial use, it is not only possible to extract a large amount of coffee at once as in the past, but also to set the coffee grounds and dispose of the extracted coffee cartridge (removal of grounds). It is extremely easy to carry out, does not require a large storage space for storage before extraction, is easy to handle, and has the additional effect of preventing oxidation of ground coffee. In addition, this invention makes it possible to almost eliminate the need for maintenance such as cleaning the filtration mechanism of the coffee boiler, which has the effect of having extremely high practical value by eliminating the complexity of conventional work for commercial use. It has the feature of playing.
