Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decoction filter bag for containing decoctions such as black tea, Japanese tea, coffee, decoctions, and dried bonito flakes.

[0002]

2. Description of the Related Art A tea bag, which is a typical example of a filter bag for decoction, is a bag made by stitching cotton gauze, or a bag made by heat-sealing synthetic fiber nonwoven fabric or synthetic fiber cloth. ,
Tea leaves are stored in the bag. When soaked in hot water, the tea bag not only brews tea but also prevents tea leaves from being mixed into the hot water.

[0003]

However, the conventional decoction filter bag made of cotton gauze has the following problems. (A) The woven thread is easily frayed from the cut end, and the frayed cotton thread may be mixed in the hot water. (B) Filtration may be incomplete due to collapse of the eyes, and a large amount of decoction may leak into hot water from the places where the eyes are open. (C) Since it is a woven fabric, the manufacturing cost is high.

Further, the decoction filter bag made of synthetic fiber nonwoven fabric has the following problems. (D) Toxic gas may be emitted depending on the components when incinerated. (E) Since the synthetic fiber nonwoven fabric does not spontaneously decompose, it cannot be returned to the ground as fertilizer after use.

The present invention has been made to solve the above problems, and an object thereof is to provide a decoction filter bag that does not have the above problems.

[0006]

Means for Solving the Problems In order to achieve the above object, a filter bag for decoction according to the present invention (hereinafter referred to as "the filter bag of the present invention") is made by confounding cotton fibers without using a binder. The cotton nonwoven fabric is sewn into a bag with a cotton thread .

[0007]

Since the filtration bag of the present invention is made of a non-woven fabric formed by interlacing cotton fibers, it does not have a weave and does not cause loosening or collapse of the yarn from the cut end.

Further, since the filter bag of the present invention is formed of a cotton non-woven fabric in which cotton fibers, which are natural fibers, are entangled without using a binder, they can be manufactured at a low cost by the hydroentangling method, etc. Does not occur. Further, even if it is discarded in the soil, it is naturally decomposed by the decomposing action of the cellulose-decomposing bacteria that are present.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following embodiments, and various modifications may be made without departing from the scope of the invention. It is possible.

FIG. 1 is a partially cutaway perspective view showing an embodiment of the filtration bag of the present invention. The feature of the filter bag 1 of the present invention is that a cotton non-woven fabric 2 obtained by entangled only natural cotton fibers without using a binder is sewn into a bag shape with a cotton thread.
Lies in the fact was.

Examples of the cotton nonwoven fabric 2 include those produced by the hydroentangling method. Non-woven fabric produced by the hydroentanglement method is formed by removing foreign matters and short fibers of cotton fibers and then forming a thin film, and the fibers forming this thin film are entangled by high-pressure water flow. It is a non-woven fabric. Therefore, this cotton nonwoven fabric has sufficient wet strength and heat resistance as a filter bag without using a binder. Usually, those having a basis weight of about ²⁰ to 50 g / m ² can be used.

When degreasing and bleaching the cotton nonwoven fabric 2,
A non-woven fabric made of natural cotton fibers may be degreased and bleached by the hydrogen peroxide method.

The non-woven cotton fabric 2 is sewn into a bag shape to filter the bag 1 of the present invention.
To achieve the above, first, the sheet-shaped cotton non-woven fabric 2 is cut into an appropriate size, the cut cotton non-woven fabric is folded and overlapped, and then a required portion such as an overlapping end portion is sewn with a cotton thread . In the proposed filtration bag 1, as shown, the lower end of the staple 4 cotton 3 the bag upper end near, or if you stick stop stitching or the like, handling more convenient.

The filter bag 1 of the present invention includes black tea, Japanese tea,
It is used to store decoctions such as coffee, decoction, and dried bonito flakes. When the present invention's filtration bag 1 containing the decoction is immersed in hot water, the decoction is infused and the decoction is prevented from being mixed in the hot water.

Since the filter bag 1 of the present invention is formed of the cotton non-woven fabric 2 in which the cotton fibers are entangled with each other, it does not cause the collapse of the filter which deteriorates the filtering function, and there is no fray of the fibers mixed in the hot water. Absent.

Further, since the cotton fiber has a function of selectively adsorbing chlorine and iron, the chlorine component and iron component in the hot water are removed, and decoction with a good aroma and taste is possible.

Further, since the filter bag 1 of the present invention is formed of the cotton nonwoven fabric 2 which is made by interlacing cotton fibers which are natural fibers without using a binder, it can generate toxic gas even if it is incinerated after use. Moreover, even if it is discarded as general waste, it is naturally decomposed by the cellulose-degrading bacteria present in the soil.

[0018]

As described above in detail, according to the filter bag of the present invention, the following practical effects can be obtained. It does not cause collapse that reduces the filtration function, and there is no fraying of the fibers mixed in the hot water.

Further, since the cotton non-woven fabric as the material can be manufactured at a low cost by the hydroentangling method or the like, the cost can be reduced.

Furthermore, even if it is incinerated after use, it does not generate a toxic gas and decomposes naturally, so that the natural environment is not destroyed.
