Abstract

PROBLEM TO BE SOLVED: To provide a multi-dripper which has a notch in a filter cloth so that it is formed in a manner capable of opening and closing, and which facilitates attaching to and detaching from a ring so that it can be mounted on a general purpose strainer.SOLUTION: The cloth-made strainer is characterized in that, in a filter for straining coffee, tea, herb, etc., a notch is provided in a part of the upper end circumference, with a catch arranged in the notch, that the filter is thereby made to engage with a filter holding ring and also with a general purpose strainer, and that a projection is prepared in one or more parts in the circumference of the filter holding ring, with an opening provided at a position or positions matching the projection(s) for the filter as described in Claim 1.

Description

          The present invention relates to a cloth filter device that can easily filter foods such as coffee, black tea or herbs, can be used repeatedly, and is easy to maintain.

          As a filter device, a filter cloth or a paper filter is used in extraction of coffee, tea, herbs, or the like. However, once it was used, it was made disposable because it was convenient.

        However, the raw material for paper is pulp, which is one of the causes of global warming due to deforestation. Reuse should be promoted to solve this problem.

Filter cloths are used many times, but after use, submerge in cold water to prevent the growth of off-flavors and germs. A temperature of 15 ° C. or lower is appropriate, storage at 20 ° C. or higher is inappropriate, and maintenance and management are required.

        Changing disposable filters creates problems that should be used effectively without discarding versatile instruments, boat drippers, conical drippers, and handle rings

        The filter cloth and the ring are of a single-piece fixed type and a removable type, and the fixed type does not completely squeeze the filter cloth, and takes up space for storage. (Patent Document 1) The removable type requires time and effort to insert a ring into the upper opening edge of the filter cloth. (Patent Document 2)

This has the following drawbacks and characteristics.
Conventionally, paper filters are discarded after use. The raw material of paper is wood and other plants, and there is a concern of generating CO2 due to global warming due to deforestation. In the case of filter cloth, it has been reused because it takes time to clean and store it, but there are only a few mania manias and cocoon shops, and very few.
However, it is possible to provide rich and rich coffee that takes advantage of the characteristics of the fabric.

        An object of the present invention is a filter cloth that can recycle coffee extraction containers that are already widely used in consideration of the environment by promoting recycling and effectively utilizing resources.

        In filtration filters for coffee, tea, herbs, etc., a notch is provided in a part of the circumference of the upper end, and a locking tool is arranged on the notch, so that a filter holding ring or a general-purpose filter A filter that can be locked.

        2. A cloth filtering instrument comprising the filter according to claim 1, wherein one or more protrusions are provided on the circumference of the filter holding ring, and an opening is provided at a position matching the protrusion.

The filter cloth and ring can be easily attached and removed, and the cleaning effect is improved compared to the fixed type. This removed the fine wrinkles and extended the use cycle of the filter cloth. Fold the cloth into small bottles with caps and store them in the refrigerator easily. The coffee liquor extracted with the filter cloth is thicker than the paper filter, and it is generally known that the coffee has a rich and smooth texture.
This reduces paper filters and re-uses equipment, providing a human-friendly environment and a taste that can only be produced in a filter cloth.

Hereinafter, modes for carrying out the present invention will be described.
In order to enable easy removal of the fixed type in FIG. 6, the conical filter cloth of FIG. 1 is formed.

    From the outer diameter opening edge (3), the inner diameter opening edge (4) is formed to have a smaller circumference by performing several steps in the tack (26) in FIG.

    By allowing the side openings (13) to be opened and closed at the joints (7) and (8), the filter cloth of FIG. 2 can be easily attached to the ring.

    Since the side opening (13) can be opened and closed, a general-purpose dripper can be attached as shown in FIG. 8, and the filter cloth does not fall even if it is inverted when the coffee grinder is discarded.

    7 is provided with protrusions (16), (17), (18) on the ring so that it does not come off the ring when it is inverted after filtration and the coffee grounds are discarded.

    Fig. 3 To install filter cloth, filter opening (9), (10), (11) is provided in Fig. 5, and the protrusions (16), (17), (18) in Fig. 2 are locked. Absent.

    Fig. 3 The filter bag (12) is lifted from the bottom, and the lower cone angle (1) and the upper cone angle (2) are bent through the upper opening (6).

Examples of maintenance usage include:
1. Invert the filter cloth, discard the coffee grounds, apply the water pressure to the outside and flow the fine particles, remove it from the ring, and wash it without using detergent.
2. Fold the filter cloth small, fill a small bottle with a lid (such as an empty bottle of jam), fill with water, and store in a refrigerator. (15 ° C or less is appropriate, storage above 20 ° C is inappropriate, and water may be tap water)
3. It is necessary to change the water in about 3 to 4 days at room temperature. However, when stored in the refrigerator, no unpleasant odor could be confirmed for 1 to 2 weeks.
4. When reused, the filter cloth is cold, so lightly rinse with water.
After that, squeeze the cloth firmly with the palm of your squeezed palm and stretch out the heel.
It ’s not as easy to clean as a paper drip, but it ’s time-consuming and you can really feel it tastes delicious.

In recent years, environmental problems have spread globally and are social problems.
Paper filters are thrown away after use, but since the raw materials for paper are wood and other plants, there is a concern of generating CO2, which is a cause of global warming due to deforestation. You can reduce the cost by using the filter cloth many times, but because it requires maintenance, it is avoided and reuse is only part of it.
However, it is possible to contribute to society if it is easy to remove and attach, facilitates cleaning and storage, promotes the use of filter cloth, and reuses paper drippers that have been used conventionally without throwing them away.
