Description

[Detailed description of the invention] This invention is a regular coffee extraction method that allows you to immediately obtain fresh regular coffee in the cup by pouring hot water through the internal hollow lid that is placed on top of the cup via a filter body with filter paper. It is related to vessels.

The purpose of this invention is to create a new type of coffee that has not been seen before in the past, which can also be used as a disposable item, and which allows you to obtain fresh, fragrant regular coffee liquid in the cup with a single touch operation. We offer regular coffee brewers like this one.

Conventional products of this type include those described in Japanese Utility Model Application Publication No. 53-3184, but all of them have drawbacks in practicality such as extraction speed, handling, production cost, and portability, but these are not fully satisfactory. The reality is that this is not being achieved.

The inventor of this invention investigated the idea of creating a disposable regular coffee brewer that can be mass-produced at low cost, and that allows you to easily drink fresh regular coffee anywhere with one-touch operation.・A regular coffee extractor according to the present invention was developed.

Next, the structure of the regular coffee extractor according to the present invention will be explained in detail with reference to two embodiments shown in the accompanying drawings.

The one shown in Figures 1 to 6 of the drawings has four elongated air holes in the circular brim of the hollow lid, and four elongated air holes in the periphery of the filter body. The one shown in Figures 7 and 8 is another embodiment in which eight raised parts are formed at regular intervals on the circular brim of the hollow lid. The peripheral edge of the filter body is provided with protrusions that fit into the eight raised portions formed in the circular brim of the hem of the hollow lid, which are recessed portions when viewed from the back side. This figure shows eight filter bodies each formed.

The one shown in FIG. 1 has a rounded protruding collar portion 1a formed on the hem portion, four air holes 2 are provided in the collar portion 1a, and a fitting groove 1b is formed on the back surface. FIG. 2 is a perspective view of the hollow lid 1, FIG. 2 is a top view of the lid 1, and FIG. 3 is a bottom view of the lid 1.

FIG. 4 is a top view of the filter body 3 fitted into the lid 1, and FIG. 5 is a bottom view of the filter body 3.

FIG. 6 is an explanatory diagram showing the usage state of this extractor.

First, to explain the configuration shown in Example 3, the configuration is such that a protruding brim portion 1a is formed on the circular periphery of the hem portion, and four air holes 2 are formed in this elongated and uniform shape. A groove 1b that fits into the peripheral edge 3a of the filter body 3 is formed on the back side of the protruding collar portion 1a, which is provided at intervals. Consisting of a lid 1 having a shape that can be stored in a hollow paper cup with a brim portion 1a, a filter body 3 that fits into the lid 1, and a filter paper 7 placed on the filter body 3. A protruding edge 3a is formed on the periphery of the filter body 3, and the protruding edge 3a removably fits into the groove 1b of the collar 1a of the hollow lid 1. An air vent hole 4 is provided.

A groove 3C is formed on the back surface of this protruding edge 3a, and the groove 3C fits into the top peripheral edge of the tip.Furthermore, there are filter holes 5 on the filter body 3, and grooves 6 that communicate with the filter holes 5, respectively.
are arranged radially.

7 is filter paper and 8 is regular coffee powder.

The paper tip 9 is indicated by a two-dot chain line in FIG.

Next, to describe how to use the extractor of this example, the hollow lid 1 has a shape and size that can be stored in the paper cup, so pull out the lid 1 from the paper cup and insert the filter body 3. When placed on the upper periphery of the paper tip, the upper edge of the paper tip will fit into the groove 3C of the filter body 3.
is fixed on a paper tip.

Next, a filter paper 7 is placed on the filter body 3. The peripheral end portion of the filter paper 7 is fixed by a fitting mechanism between the protruding edge 3a of the filter body 3 and the collar portion 1a of the hollow lid 1.

In this case, if the filter body 3 and the hollow lid 1 are fitted in advance and the filter paper 7 is also fixed, then the combined body can be mounted on the top.

Next, regular coffee powder 8 is placed on this filter paper 7, and hot water is poured from the top opening of the lid 1 fitted with the filter body 3. The regular coffee powder 8 is filtered through the filter paper 7, and the lower paper cup 9 is poured. This allows you to get fresh regular coffee liquid.

In this case, by pouring the hot water all at once up to the vicinity of the top opening of the lid 1, a portion of the pot can be extracted at a sufficient concentration, eliminating the need for pouring hot water several times.

Next, another embodiment II will be described. It is a hollow lid 10 having a structure as shown in FIG.
Eight rising portions 10b are formed at regular intervals on the front side of 0a, and eight rising portions 10b are formed on the brim portion 10a of the hollow lid 10 on the peripheral edge of the filter body 11 that fits thereon. As the rising portion 10 b rises, the protruding portion 11 is fitted into the recessed portion from the back side.
Eight a are formed.

A filter hole 12 is formed in the center of the filter body 11, and eight rod-shaped protuberances 13 are radially provided in the filter hole 12 toward the filter hole 12.

. The case of this example is also the same as the case of Example 1, but instead of the pores, there are provided in the raised part 10b of the lid 10 and in the filter body 11 that fits into the recess on the back side of this raised part 10b. The gap between the protrusion 11a and the protrusion 11a acts as an air vent.

The filter body 3 or 11 shown in the above two embodiments is provided with a filter hole 5 or 12 in the center, and eight grooves are formed radially around the filter hole 5 or 12. 6 or a raised portion 13 is formed to communicate with the filter hole 5 or 12.

This is done by creating a space between the filter paper and the filter surface, reducing the area where the filter paper comes into close contact with the filter surface, eliminating the situation where filtration is done only at the filter holes, and further reducing the amount of coffee extracted. It is designed to prevent the surface tension phenomenon that occurs in the filter holes, which makes it difficult for extracted coffee to fall, and to speed up the extraction process by increasing the penetration of hot water into the coffee grounds. result,
Coffee of sufficient concentration can be extracted immediately by pouring hot water into the lid once.

In the regular coffee extractor according to the present invention, the hollow lid and the filter body can be removably fitted together, and the filter paper can be perfectly positioned in a fixed position without using an adhesive or the like. The filtrate leaks out during filtration.
There is no danger of it falling downwards.

In addition, coffee can be extracted extremely easily by pouring hot water once, and the extraction speed is fast, so there is no risk of the extracted coffee cooling down like in the past.

Furthermore, since it can be stored in a paper cup along with sugar, milk, etc., it is convenient to carry, can be easily used outdoors, and can be mass-produced at low cost, making it highly practical.
