Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for extracting a cup of black tea capable of extracting a cup of delicious black tea.

[0002]

2. Description of the Related Art The following three methods are mainly used for making tea in a coffee shop or restaurant. Tea leaves are steamed in hot water for a certain period of time using a pot made of pottery or glass, or a meliol. Simmer tea leaves in hot water using a hot pot. Put a tea bag in a tea cup and pour hot water,
Extract directly.

[0003] In the above method, when a cup of boiling water is put into a teapot or the like, the teapot or the like absorbs the heat of the hot water, so that the temperature of the water drops, and the original taste of the tea leaves is sufficiently extracted. Is not possible, and hot tea is extracted. Therefore, usually in a coffee shop, etc., in order to prevent such a drop in hot water temperature and add delicious black tea,
Even if one cup is ordered, he makes more than two cups of tea at once. In addition, when an order for one person's tea is made, almost two cups of tea are made and served. The term "the amount of tea + a cup for the pot", which is commonly referred to as a measure of the amount of tea leaves, is the conventional wisdom to prevent the temperature of the hot water from dropping and to add delicious tea.

[0004] In the above method using a hand pot,
Because the diameter of the hand pot is wide, hot water evaporates easily during boiling. For this reason, the relationship between heat and boiling time is difficult, and skill is required to repeatedly extract a certain taste in a certain amount of one cup. Therefore, this method is not general.

[0005] Furthermore, the method of putting a tea bag in a tea cup has been widely used especially in ordinary households because of its simplicity. However, at present, most of the black teas on the market are not contained in the tea bag. It is rose tea (leaf type). It is conceivable that this rose tea (leaf type) is put into a paper or polyethylene tea pack to make a tea bag, but when the required amount of rose tea is put into a tea pack and used, the tea leaves absorb moisture. To spread inside the tea pack. As a result, the movement of the tea leaves due to the convection movement of the hot water is restricted, and a delicious black tea cannot be made.

[0006] The tea leaves used as tea bags are of the type called "dust", and are finely chopped and processed so that black tea can be extracted in a short time of one minute. On the other hand, rose tea (leaf type)
"Orangepekoe" or "broken orangepeco"
koe) ”, which requires a minimum of three minutes for the extraction of black tea. Therefore, when this rose tea is used as a tea bag, the temperature of the hot water in the tea cup decreases due to the decrease in the temperature of the hot water in the tea cup, as described above. The tea taste cannot be fully extracted and the tea cannot be served.In today's tea boom, the interest in tea leaves of a wide variety of teas is gradually increasing, There is no simple device for extracting delicious black tea, and in the above-mentioned conventional technology, even if it is possible to obtain delicious black tea by making more than two cups at a time, it is easy and only one cup at a time. Delicious tea cannot be added, so if you want to make only one cup, you need to make two cups, which wastes tea leaves and heat.

In order to taste a wide variety of tea leaves, it is best to use equipment such as a teapot among the above-mentioned prior arts. There are problems, and in addition, the following problems exist. (A) Since the opening at the upper end of the pot is generally small with respect to the capacity, it is inconvenient to perform processing such as taking out tea leaves after extracting black tea. (B) It is difficult to wash the inside of the pot, and it is difficult to remove the brown spots. (C) In addition to a tea cup, a tea pot or the like occupies a space on the table, so that in a Japanese coffee shop or the like where the table is generally small, the tea pot becomes an obstacle. (D) Since the teapot itself is expensive, it is naturally handled with care, and as a result, the frequency of drinking tea is reduced,
The original taste of black tea is not generally known. (E) The method of making tea using a teapot is described in related books for a long time. However, the influence of this method makes it difficult for people who make tea to prepare tea more than necessary. If you can't make it delicious, you lose your confidence and lose your quest for tea.

[0008] As a person who is interested in coffee peels off instant coffee, extracts and tastes it with his own hand using a paper dripper, which is a coffee appliance, and pursues the taste of tea, It is suitable for a person who is interested in extracting tea and exploring delicious tea, and it is a simple equipment like a paper dripper that can add only one cup of delicious tea. Appearance is strongly desired.

The inventor of the present invention carried out one experiment, considering that the above-mentioned "delicious black tea" has a great relationship with the temperature of hot water for extracting it. FIG. 3 shows a graph obtained based on the data shown in Table 1. This experiment is
Hot water was poured into all kinds of containers, and the change over time in the temperature of the hot water in the containers was examined. Specifically, 180 cc of boiling water is put in each container in principle, and the containers are preheated. After 30 seconds, the hot water is discarded, and after 30 seconds, 180 cc of boiling water (360 c
c) in a container. The room temperature of the laboratory was set at 24 ° C.

[0010]

[Table 1]

Containers include pottery pots for tea, pottery pots for tea (when hot water of 360 cc is put in), coffee server glass pots, pottery tea cups, porcelain tea cups, porcelain mugs, enamel mugs. , Enamel mug (36
0 cc boiling water), a glass pot for herbal tea.

Until now, in coffee shops and restaurants, etc., two or more cups (360 cc) of tea leaves and boiling water are put into a pot made of black tea and steamed for three minutes to extract "delicious black tea". In this experiment, the pottery pot for tea with two cups of hot water was indicated by
The temperature of the boiling water after 3 minutes in this container is 83 ° C. By the way, one cup (1 cup) in the same pottery pot for tea
The one with 80 cc of hot water is indicated by, and the temperature of the hot water after 3 minutes is 76 ° C., which is considerably lower than that when two cups of hot water are added. This is why you can't get good tea. When tea is extracted from a tea bag in a tea cup and is to be drunk, it is considered to be the best after 1 minute. This tea cup is indicated by, and the hot water temperature after one minute has passed is 80 ° C.

From these facts, in this experiment, in consideration of the fact that a container for producing delicious black tea uses rose tea instead of a tea bag, the temperature of the hot water poured into the container is at least 3 minutes later. It can be seen that the temperature must be 80 ° C. or higher. As a container satisfying these requirements, the inventors of the present invention have found an enameled mug shown below.

Further, the present inventor has conducted an investigation on whether or not there is a device capable of producing a delicious cup of black tea based on such experiments in the past. As a result, it was confirmed that there was a teapot type tea utensil (Japanese Utility Model Publication No. 4-18519) as a similar device. this is,
In the pot body with a spout, a strainer with a strainer on the front and the bottom is made detachable, and a lid is made detachable on the upper part of the pot body, and tea leaves are poured into the strainer and hot water is poured. Is extracted and poured into a cup or the like from the spout of the pot body. Another herbal tea cup with a strainer is also known. In this method, a tea strainer having a plurality of through holes in a cup body is made detachable, and a lid is provided to cover the cup body. The herbal tea is put in a tea strainer, hot water is poured, the tea strainer is removed after extraction, and the herbal tea extracted in the cup body is directly consumed as it is.

[0015]

However, in the former teapot type tea utensils, the purpose is to extract tea and then pour it into a cup or the like from the spout of the pot body and drink it. As with teapots, it is not possible to make a delicious cup of tea due to the drop in hot water temperature. For the same purpose, a strainer is provided only on the front surface and the bottom surface of the strainer, and has a specific structure such that tea leaves do not hinder tea pouring out.

The latter herbal tea cup with a tea strainer is made of earthenware and corresponds to the earthenware tea cup shown in the above experimental results.
Down to Therefore, even if this is used as it is for extracting black tea, it is not possible to produce a delicious black tea.
In addition, this herbal tea cup with a strainer is expensive and therefore difficult to spread. Further, the herb used as the material of herbal tea is generally a dried leaf, stem, flower, or the like of a flower, and herbal tea is a liquid obtained by extracting the ingredients. Therefore, when making herbal tea, a hot water temperature of 80 ° C. or higher is not required.
On the other hand, in the case of black tea, since it is necessary to maintain 80 ° C. or more for 3 minutes, this tea cup with a ceramic tea strainer for herbal tea is not suitable for black tea extraction.

Therefore, an object of the present invention is to make it possible to easily and easily put even a black tea using one cup of rose tea, and to take out the rose tea after extraction and wash the utensils easily.
