JPS5940910Y2 - Simple drip coffee maker using filter coffee pack - Google Patents

Description

[Detailed explanation of the idea] This invention relates to a simple drip coffee maker.

In order to give the cord a certain taste, it is necessary to always use a certain amount of coffee powder.

Therefore, pre-packing and vacuum-wrapping batches of coffee powder makes it durable for storage, and its small size makes it convenient to carry.

However, a simple drip coffee maker using a conventional coffee pack is as shown in Figures 1 and 2, but Figure 1 shows a conventional coffee pack with the lower end partially cut off. FIG. 2 is a side view of the simple drip coffee maker, and FIG. 2 shows it viewed from below as indicated by arrow R in FIG. 1.

The container 1 is made of plastic or the like, and has a truncated conical shape that tapers downward, and has a protruding part 2 protruding downward, and the bottom part 3 of the protruding part has a window of an arbitrary shape, as is clear from FIG. Department 4 is there.

A filter paper 6 is spread out on the stepped part 5 above the protrusion, and a filter paper 7 is spread inside the bottom part 3 of the protrusion. One serving of coffee powder 8 is completely enclosed between the door papers 6 and 7.

When in use, the container 1 is placed on top of a coffee cup, and the required amount of hot water is poured all at once from above, and the hot water passes through the filter paper and the coffee powder 8.

However, this simple drip coffee maker is uneconomical because the container and the container are used up after each use, and the coffee powder is completely packed between the upper and lower filter papers, so even if hot water is poured The drawback was that the powder did not have enough room to swell, making it difficult to make delicious coffee.

This invention aims to eliminate these drawbacks and provides a simple drip coffee maker in which a filter coffee pack and a device for making coffee using the filter coffee pack are separated.

Since FIGS. 3, 4, 5, 6, and 7 show an embodiment of the present invention, these figures will be explained below.

FIG. 3a is a perspective view of the filter coffee pack 20 of the present invention, and FIG.
It consists of 2 doors and is entirely made of paper.

One serving of coffee powder 23 is sealed in the tray 22, and the volume of the tray 22 is such that the volume of the coffee powder per serving is approximately % of the volume.

Therefore, when a batch of coffee powder is placed in the tray, the upper portion of the tray will form a void 24.

Also, 1 is the diameter of the brim 21 of the filter coffee pack 20, 1' is the diameter of the tray 22, and I I+ is the depth of the tray 22.

At the time of sale or storage, this filter coffee pack 20 is sealed 26 airtightly or in a vacuum with synthetic resin or aluminum foil, as shown in the conceptual diagram of the packaging in FIG.
Before use, the bag is torn open and taken out for use, making it convenient to carry and store, and retains its aroma and taste for a long time.

Next, FIG. 5 shows a simple drip coffee maker 27 for making coffee using this filter coffee pack. Inner cylinder 4 shown in the side sectional view of Figure 5A
It is composed of 0.

The outer cylinder 30 is made of plastic or the like, and the outer cylinder main body 31 is a truncated conical cylinder that tapers slightly downward, and has a shallow cylindrical protrusion 32 at the bottom. The upper part is a stepped part 33.

FIG. 5C shows the outer cylinder 30 viewed from the direction of the arrow S in FIG.
4 has a window 35 of arbitrary shape, as seen in FIG. 5C.

When in use, the filter coffee puncture is inserted into the protrusion 32 and step 33 at the bottom of the outer cylinder, so the inner diameter of the step 33 is equal to the diameter 1 of the brim 21 of the filter coffee pack. The inner diameter of the protrusion 32 is the diameter 1' of the dish 22, and the inner depth of the protrusion 32 is the depth 1'' of the dish 22.

The inner cylinder 40 is also made of plastic or the like, and the inner cylinder main body 41 is made to fit snugly inside the outer cylinder main body 31, and the tray part 22 of the filter coffee pack 20 is placed in the center of the bottom. A hole 48 having the same diameter as diameter 1' is bored, and a bottom protruding edge 47 surrounds the hole.

In use, as shown in FIG. 6, by placing the outer cylinder 30 on top of the cup 50 and inserting the filter coffee pack into the bottom of the outer cylinder, the tray part 22 of the filter coffee pack will fit into the protrusion 32. The collar portion 21 of the filter coffee pack is inserted into the stepped portion 33.

Next, when the inner cylinder 40 is inserted into the outer cylinder 30, the bottom protruding edge 47 of the inner cylinder will sandwich the collar part 21 of the filter coffee pack between the stepped part 33 of the outer cylinder, and the filter coffee puncture will occur. The inner and outer cylinders are fixed to prevent them from floating up.

The fixing method may be by using screw threads and thread grooves provided at corresponding positions on the outer surface of the side wall of the inner cylinder and the inner surface of the side wall of the outer cylinder, or by screwing into the upper edge of the outer cylinder. It may be attached to a flange groove 57 provided on the upper edge of the inner cylinder, or it may be an elastic hook 58 that holds the inner and outer cylinders and the lid.

Therefore, hot water for each batch is poured into the inner cylinder at once.Since the filter coffee pack is made entirely of filter paper, it becomes moist and soft, but as mentioned above, the brim 21 is at the bottom of the inner cylinder. Since the inner and outer cylinders are fixed by being sandwiched between the chime 47 and the stepped part 33 of the outer cylinder, it is possible to create a plate in which coffee powder is enclosed without floating, turning over, or forming into a ball. The portion 20 is sufficiently supported.

The hot water poured into the inner cylinder drips from the filter paper on the top of the dish part 22 evenly into the coffee powder 23 in an appropriate wrinkle shape, and the coffee powder absorbs the hot water, swells, and fills the cavity 24. It gets steamy, and all the essence of the coffee is drawn out and drips into the cup 50 from the filter paper at the bottom.

If the filter coffee pack does not have enough voids 24 for the coffee to absorb hot water, swell, and become steamy, the coffee will become clogged, which will waste time and result in poor tasting coffee.

In this case, the upper filter paper is required to drip hot water in an amount that matches the rate at which the coffee powder absorbs hot water and swells.

Also, if the water gets cold, the taste of the coffee may deteriorate.
It is better to use the lid 53.

However, if the lid is airtight, hot water will no longer drip, so as shown in FIG. It is more effective if the upper edge of the tube and the lid do not come into close contact with each other.

Once the coffee has finished dripping, remove the inner cylinder, throw away the filter coffee pack, and fit another filter coffee pack to make the next batch of coffee.This coffee maker 27 can be used over and over again, making it economical. Moreover, since this filter coffee pack is made entirely of filter paper, it has the practical benefit of being very inexpensive, and it is also convenient to carry as it rolls and is small. If the coffee is sealed and packaged, it can be stored for a long time without reducing the taste or aroma, and since the space 24 is provided, delicious coffee can be obtained.
