Description

[Detailed explanation of the idea] The present invention relates to a coffee filter.

The main body of conventionally commercially available coffee drippers is made of ceramic or plastic, and most of them are shaped like a coffee cup with a hole in the bottom.

These items are very durable and therefore expensive, semi-permanent, and generally not disposable.

Furthermore, the main body of this conventional dripper cannot be folded and must be carried around in the same shape as when in use, making it bulky and unsuitable for portability.

The present invention was developed to solve this problem, and it is very compact and can be folded and carried around, making it convenient for travel, etc., and it can be provided at a low cost.Furthermore, it is a completely new type of gutter crusher that can be used as a drip type. We offer coffee filters that can also be used in formulas.

In order to achieve this purpose, the present invention uses hot water-resistant and water-permeable nonwoven fabric or paper as a material, and uses this material as a material with two
It is characterized in that the sheets are stacked one on top of the other, at least one common side is made into an opening, the remaining sides are sealed, and a notch is formed along one side of the opening to provide a binding part.

The present invention will be explained below based on drawings showing an example of implementation.

In the figure, 1 is a hot water resistant and water permeable material 2 such as non-woven fabric or paper, which is folded in half into a substantially square shape, one side adjacent to the folded side is adhered by heat welding, etc., and an opening is formed on the remaining two sides. 3, an L-shaped notch 4 is formed along the vicinity of the two sides, and the outer side of the notch 4 is used as a binding part 5.

Reference numeral 6 denotes the adhesive portion, which is indicated by diagonal lines.

Note that the material 2 such as nonwoven fabric or paper contains synthetic fibers so that it can be heat-sealed.

The material 2 of the filter 1 may be made from synthetic fibers having hot water resistance and water permeability, such as polyester, acrylic, and polypropylene.

Next, a method of using the filter 1 configured as described above will be explained.

First, hold the apex of the opening 3 and insert the filter 1 into the second
Open the filter 1 as shown in the figure, place the filter 1 in a cup 7 as shown in Figure 3, and then pour an appropriate amount of roasted ground coffee powder (not shown) into the filter 1. If the cup 7 fits very well, just pour in the hot water and the coffee ingredients will dissolve out after a few tens of seconds, then slowly pull up the filter 1 by the edge 5 and remove the coffee that has passed through the filter 1. can fit into the cup 7 and pour coffee into it.

This is a completely new method of entering expressions.

If the filter 1 is difficult to fit into the cup 7, as shown in Fig. 4, the filter 1 can be suspended from the hook 8 by the binding part 5, or lifted from the cup 7 by holding it. Add an appropriate amount of ground coffee powder,
By pouring hot water into the filter 1 from one end of the filter 1, coffee can be poured in a drip style.

Although the filter 1 is made by folding one piece of material 2 in half, it is also possible to overlap two substantially square pieces of material and glue their two adjacent sides together.

In addition to the substantially square shape, the shape of the filter 1 may be, for example, a modified quadrilateral such as a rhombus, a fan shape, or the like.

In the case of a fan shape: Since the sides are arcuate, it is only necessary to form a set part along that side by using that side as an opening.

The coffee filter of the present invention can be implemented as described above, and the following effects can be obtained.

■ The filter can be folded into a very compact flat shape, so it is not bulky and is convenient to store and carry.

■ Because the filter is thin, the heat of the hot water is not absorbed by the filter, so there is no need to warm it up before using it, unlike with ceramic drippers. ■ Comes with a built-in part, making it easy to use. Also, it is easy to dispose of it by holding the assembled part.

■ Dobuzuke can be used either in the type or drip type.

■ Can be produced in large quantities using a bag-making machine and provided at low cost.
