Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a disposable type device that is placed on a container such as a drinking container and used for brewing coffee, black tea, green tea, etc.

<Prior art> A coffee extractor that is placed on a drinking container such as a coffee cup and poured hot water from above is well known.
There are many types. Among these, many of the disposable types are used in principle as shown in FIG. That is, the extractor 1 includes a cylindrical main body 2 made of paper and tapered at the bottom, and a filter paper 3 arranged as a lining by adhering to the upper part of the inner peripheral surface of the main body 2.
It consists of. In the figure, 6 is the adhesive part. A supporting stand 4 is formed separately from the main body 2, is fitted into the lower part of the main body 2 like a collar, and is placed on the upper edge of the cup 5 via this part. In addition, before being used in this way, all the devices are folded flat so that they can be stored without taking up much space. Such a conventional extractor 1 does not have a structure that supports the bottom of the filter paper 3.

<Problems to be Solved by the Invention> The above-mentioned conventional extractor has a problem in that, for example, when brewing coffee, the ingredients of the seaweed are extracted along with the coffee ingredients, which impairs the original flavor of the coffee. Furthermore, since the filter paper of the extractor is not supported at its bottom, when filter paper is used that has a pressure-bonded seam at the bottom, there is a problem in that when hot water is poured, the seam easily separates and creates holes. The biggest problem is that because the hot water flows down at such a high rate, sufficient extraction is not possible and the original good flavor of coffee cannot be produced.

<Means for solving the problem> The means of this invention consists of a paper main body that is formed into a substantially cylindrical shape and placed on the opening edge of the container during use, and a filter that is formed separately from the main body and installed inside the main body. In the extractor for coffee, etc., the main body is formed into the cylindrical shape, and tongue-like portions are provided at opposite positions on the lower edge, and the tongue-like portions are bent inward, respectively. The device is characterized in that the bottom wall portion of the main body is formed by being engaged with each other, and that the bottom wall portion is provided with a relatively small liquid outflow hole.

<Function> According to the means of this invention, the extractor main body has a bottom wall portion, and the bottom wall portion is equipped with a relatively small liquid outflow hole, so that when coffee etc. flows out, the filter paper is removed. is supported on its bottom wall,
Even if the filter paper has a seam formed by pressure bonding, no weight is applied that would cause it to tear. Furthermore, due to the presence of the bottom wall with liquid outflow holes, hot water poured into the extractor from above gradually flows down.

<Example> FIGS. 1 and 2 show the extractor 10 in use, with reference numeral 11 representing the main body and reference numeral 12 representing the filter.

The main body 11 is formed by assembling cut laminated paper as shown in FIG. Third
The cut material for the main body shown in the figure has bending lines 13, 14,
Side wall parts 18, 1 divided by 15, 16, 17
9, 20, 21 and tongue pieces 22, 23.
It also has a protruding piece 25 that serves as a handle. 26 in the diagram
a, 26b, 27a, and 27b each indicate a cut.
To assemble it, fold each fold line 13 to 17 into the same valley fold on one side of the paper.
It is bent 90 degrees and the notches 26a and 26b and the notches 27a and 27b are engaged with each other.
Thus, the main body 1 as shown in FIGS. 1 and 2
It becomes 1. That is, the main body 11 has a short rectangular cylindrical shape with a narrow lower part, and a handle 28 and a bottom wall part 29 are attached thereto. Since the tongue pieces 22 and 23 of the bottom wall portion 29 are each substantially trapezoidal, an elongated triangular liquid outflow hole 30 is formed therein. This liquid outflow hole 3
The size of 0 is determined by how the shapes of the tongues 22 and 23 are determined.

The filter 12 has an upper edge 3 as shown in FIG.
1 is the opening, the bent edge 32, the crimped edge 3
It is a commercially available product in the form of a bag with 3.34 mm. This is shaped appropriately so that a bottom wall portion roughly corresponding to the bottom wall portion 26 is formed, and the upper portion is opened to form the main body 11.
to be contained within.

This extractor 10 is used by fitting the lower end into a punched hole 36 of a support base 35 shown in FIG. 4 and placing it on a cup. For example, when coffee powder is put in and boiling water is poured over it, the hot water collects in the extractor 10 and gradually flows down into the cup from the outflow hole 30. Therefore, the extraction time is appropriate for coffee extraction, and coffee with good flavor can be brewed. Further, a crimped seam is located on the bottom wall of the filter 12, but a bottom wall 29 is located on the main body 11.
exists and supports the weight of the filter 12 and the coffee grounds and hot water inside it, so the joint will not break. In addition, the storage state before use is, for example, folded in half along the bending line 14.

In the above embodiment, the main body 11 has the notches 26a,
26b are shown to be engaged with each other to form the handle 28, but the protrusions 24 and 25 may be formed into a handle by bonding them together as a bend line without providing cuts at the base thereof. . Furthermore, such a handle may be omitted in some cases. In that case, it is necessary to connect the side walls 18 and 21, but for example, a tongue piece may be provided on one side wall part via a bending line and it may be glued to the outer surface of the other side wall part. In this case, even if it is glued, it will have little effect since it is on the outside surface. In addition, in a configuration without a handle, if the size of the cup is appropriate to some extent, the cup can be placed on the upper edge of the cup without using the support stand 35.

Further, in the above embodiment, the triangular outflow hole 30 is formed by making each of the tongue pieces 22 and 23 forming the bottom wall portion 29 of the main body 11 into a trapezoid, but the shape of the outflow hole is It is not limited to a triangle, but may be any suitable size. Therefore, each of the tongues may be rectangular and punched holes may be provided at appropriate positions on the tongues. moreover,
In addition, a configuration may be adopted in which the bottom structure of a conventional paper carton is assembled without using glue, and appropriate punched holes are provided.

<Effects of the invention> According to this invention, there is a bottom wall part in the body of the extractor, and an appropriate liquid outflow hole is provided in this, and hot water gradually flows down through the outflow hole, so that coffee, etc. Extraction takes place very well. Furthermore, due to the presence of the bottom wall, a commercially available paper filter can be used as is. Moreover, since no glue is used on the bottom wall, the flavor of coffee etc. is not impaired. The presence of the bottom wall serves to maintain the cylindrical shape of the main body, making it an extremely easy-to-handle device.
