Description

[Detailed description of the invention] [Industrial application field] This invention is a strainer mainly used when making drip coffee. More specifically, it relates to a strainer in which coffee powder is placed in a strainer bag and hot water is poured over the bag to drip it.

The strainer of the present invention uses a disposable strainer bag and is ideal for making drip coffee at home or at work, but it can also be used as a strainer for oolong tea, black tea, green tea, etc. .

[Conventional technology]

For example, in order to obtain delicious coffee with a rich flavor, the temperature of the water and the way it is poured are important points. It is important to devise ways to extract the components of the coffee powder while expanding and steaming it evenly. Therefore, it is ideal to pour the molten metal according to the following procedure. That is, first, pour an appropriate amount of boiling water slowly and gently to evenly moisten the entire coffee powder and steam it, then increase the amount (rate) of pouring water, and gradually pour it toward the end. Slow down the hot water speed (amount). Ideally, the coffee liquid from which the components have been extracted as described above should be dripped in as natural an atmosphere as possible.

By the way, conventionally, in coffee shops and the like, a support device with a ring of an appropriate size formed on the upper end and a cloth straining bag (this bag can be washed and used repeatedly) are used.
The opening of the bag is expanded, the upper edge is folded back into a ring, the folded part is tied with a string, the bag is attached to a support, the coffee grounds are poured into the bag, and boiling water is poured from the top of the bag. A container placed at the bottom collects the coffee liquid that drips from the grain of the fabric to make coffee.

According to this method, the above-mentioned requirements can be satisfied, so that delicious coffee with rich flavor can be made.

However, this method can be adopted because it uses a cloth straining bag, and if a disposable straining bag made of filter paper is used, it is impossible to apply the above technique as is.

Therefore, conventionally, as a coffee dripper (strainer) using a disposable strainer bag, the one shown in Fig. 10 has been generally used. To explain with reference to the figure, 1 is a container body formed in the shape of an inverted cone, etc., with an open top end, and the bottom of the container 1 is configured in a dish shape so that the container 1 can be placed on a coffee cup 2. A mounting table 3 is integrally formed therein, and an arbitrary number of small holes 5 are bored in the bottom plate 4 of the container 1, and 6 is a handle protruding from the outer wall surface of the container 1. Reference numeral 7 indicates a straining bag made of filter paper or the like with an open top end, and 8 indicates coffee powder.

The conventional product is constructed as described above, and the straining bag 7 is housed in the container body 1, and an appropriate amount of coffee powder 8 is placed in the bag 7.
The container 1 is placed on the cup 2, and hot water is poured onto the coffee powder 8 from the upper end of the bag 7 to make drip coffee.

[Problem that the invention attempts to solve]

According to the above-mentioned conventional product, drip coffee can be easily made. However, on the other hand,
The conventional product described above has problems that should be improved in the following aspects.

(b) In the conventional product, a strainer bag 7 is placed inside the container 1, coffee powder 8 is placed in the bag 7, boiling water is poured from the top to extract the components of the coffee powder, and this coffee liquid is poured into the bottom plate of the container 1. 4 is configured to drip into the cup 2 from the small hole 5,
Hot water will be poured into the vessel 1. Therefore, even if you pour hot water while adjusting the pouring amount (speed), the hot water will evenly infiltrate the entire coffee grounds, and the coffee grounds will not be steamed evenly. 1
The inside becomes like a bathtub of coffee liquid. As a result, this becomes a factor that reduces the flavor of coffee.

(b) In the conventional product, the periphery of the straining bag 7 is covered by the inner wall surface of the container body 1, so that dripping does not occur in a natural atmosphere. Therefore, this point also becomes a factor that impairs the flavor.

(c) In the conventional product, the hot water drips through the small hole 5 while contacting the inner wall surface of the vessel body 1, so there is a problem that the temperature of the hot water decreases.

The object of the present invention is to provide a strainer that can solve all of the problems mentioned above with respect to the conventional products.

[Means for Solving the Problems] The structure of the present invention for solving the above problems will be explained using FIGS. 1 to 6, which correspond to the embodiments. A strainer bag 1 is placed on the edge of the pouring spout 13 of the mounting frame plate 12 in which the sprue 13 is opened.
