Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tick-proof futon which is impermeable to mites.

[0002]

2. Description of the Related Art Conventionally, as futon mites prevention measures, drugs are broadly classified (preventing mites from mitigating with repellents, weakening and killing mites with insecticides that do not adversely affect the human body, Furthermore, there is also one that uses the radiant energy effect of the ceramic fine particles contained in the fiber and has the ability to radiate far infrared rays.) And one that physically prevents mites from entering.

[0003] As a chemical agent, the material used for the front and back sides of the futon is treated with a repellent or insecticide agent, or the futon cotton is treated with a chemical agent and has a tick-proof tick-proof fiber. I used or not, but for the futon side fabric that directly touches the human skin, I used an ordinary non-medicinal fabric and overwhelmingly used tick-proof cotton as batting. .

As an example thereof, there is a pest control pouch described in Japanese Utility Model Publication No. 3-16874. this is,
One side of the bag body is made of a fabric made of fibers containing ceramic fine particles having far-infrared radiation ability, and the other side is made of a fabric containing an insecticide, a repellent insect repellent or both of them. , When the bag is dried in the sun, kill the mites whose repellent type insect repellent was prevented from escaping to one side with far infrared heat energy from the other side, or conversely escape from the heat energy from the other side. The mites are killed on one side with an insecticide to be exterminated.

[0005]

However, even if the mites are exterminated, the carcasses will become dust causing new allergic asthma and rhinitis, and it is essential to prevent the mites from physically entering the futon. is there. Therefore, since the body length of ticks is usually 400 μm to 500 μm, it is desirable to use a futon with the eyes of the front and back fabrics so as not to make a gap larger than this. If such a front and back side fabric is used, mites cannot enter the futon through the front and back side fabric, but when quilting is performed to fix the batting and the front and back side fabric, a sewing hole is formed by the sewing machine. Then, there is a problem that mites enter from between the seam and the sewing thread.

For example, as shown in FIG. 5, a futon 50 is made by filling a filling material 56 between a front side cloth 52 and a back side cloth 54 and sewing it. Also, the front and back fabric 5
The linings 2, 54 and the batting 56 are fixed by a sewing thread 64 by performing a quilting process. The quilting process is generally performed by using a sewing machine for a quilt and using a thread and a sewing needle. The mating edges of the front and back fabrics of the futon 50 cover the front and back fabrics 52 and 57 with a tape-shaped cloth 60,
The hem processing for sewing with the sewing thread 62 is performed on the entire circumference. Hem is an English word for "hemi" (such as a handkerchief),
In the case of a futon, it means the rim of the surroundings. In this hemming, holes 66 are formed for sewing, and mites can easily enter the inside of the futon through the holes 66.

The present invention has been made to solve the above-mentioned problems, and provides a mites-proof futon that prevents invasion of mites through the needle holes formed when sewing the mating edges of the front and back fabrics. Is intended.

[0008]

In order to achieve this object, the mite-proof futon of the present invention is a mite-proof futon in which batting is inserted and arranged between fine front and back side fabrics that are impermeable to ticks. The periphery of the cloth is welded by a member that can be melted by heat.

The member which can be melted by heat is
You may use the resin which has high flexibility.

[0010]

The function of the present invention is as follows.
A batting is inserted and arranged between fine front and back fabrics that do not allow mites to pass through, and the periphery of the front and back fabrics is welded by a member that can be melted by heat.

Further, the resin having high flexibility is heated to weld the peripheries of the front and back side fabrics.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the mite-proof futon according to the present invention will be described in detail below with reference to the drawings.

First, the outline of the structure of the mite-proof futon of this embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a configuration diagram of the tick-proof futon, and FIG. 2 is a partially enlarged sectional view of a mating edge 4.

The anti-tick futon 1 is made of cloth 5 and 7 on the front and back sides.
A fabric made of ultra-high-density fiber is used as the material, and a joint portion 41 formed of a resin having a high flexibility is provided between the front and back fabrics 5 and 7 with the edge 4 sandwiching the batting 3 therebetween.
It is configured by welding.

Examples of the fabric include cotton, hemp, wool, silk and other natural fiber spuns of plants and animals, nylon and polyester,
Woven fabrics made of synthetic fiber spun such as acrylic and vinylon and recycled fiber spun such as rayon and acetate are used.

As the batting 3, a tick-proof cotton obtained by treating natural fibers or synthetic fibers with a repellent insect repellent or insecticide is used.

In order to fix the batting 3 to the front and back fabrics 5 and 7, as a quilting process, a sewing thread 12 is sewn in a grid pattern.

The joint portion 41 is injection molded from a material such as soft vinyl chloride.

Toluamide compounds and nicotine compounds are used as the repellent insect repellents, and pyrethroid compounds and organophosphorus compounds are used as the insecticides, but they may be used in combination. .

Next, a method of manufacturing the joint portion 41, which is the main part of this embodiment, will be described with reference to FIGS.

FIG. 4 is a partial cross-sectional view of the injection molding machine 25 equipped with a mite-proof futon. First, the batting 3 is inserted and arranged between the front and back side fabrics 5 and 7, and then a hole 19 is made in the edge 4 of the front and back side fabric by a punching machine (not shown). This hole 19 corresponds to a seam when sewing, and the hole is opened according to a desired joining state such as a serial arrangement or a zigzag arrangement.

Next, the joint portion 41 is molded on the edge 4 by an injection molding machine. This injection molding machine is mainly composed of a fixed mold 29, a movable mold 31, and an injection mechanism (not shown) for injecting resin into both molds. The mold chamber 44 of the injection molding machine 25 is formed by combining the fixed side mold 29 and the movable side mold 31.
