Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an invention in which a charcoal sheet is formed from charcoal or bamboo charcoal powder or fine powder or charcoal fiber, and this charcoal sheet is used for bedding or other products.

[0002]

2. Description of the Related Art Charcoal is a porous material and has excellent adsorptivity.
It is widely used as a hygroscopic material and deodorant, and also has a far-infrared ray effect and an effect of generating negative ions, so it is also known as a health material.

Therefore, some beddings using this charcoal have been developed as shown in Japanese Patent Application Laid-Open No. 8-56997.

[0004]

This kind of bedding has the drawback that it uses a special substance called charcoal powder to stain the bedding black even with a small amount of leakage. When completely sealed with such a material, there is a problem that moisture absorption / deodorization characteristics cannot be obtained, so that a complete product cannot be obtained.

[0005] In order to maintain the moisture-absorbing properties of charcoal, it is necessary to perform a drying operation such as drying in the sun. But,
With conventional products, the charcoal powder itself is sewn into the bedding,
In addition, even in the case of sheet-like ones, most of them were large and hard to put in and out. Furthermore, when the temperature is low, such as in winter, the charcoal cools down in harmony, and the moisture absorbed further promotes the temperature drop of the charcoal itself. I sometimes felt.

[0006]

In view of this point, the inventor has made various trial productions and arrived at the present invention. As the carbon material, charcoal or bamboo charcoal powder or fine powder or fiber was carbonized. Using a charcoal fiber that has been breathable, it is also breathable, and it is laminated with a film on the back side of two thin and dense spun pond nonwoven fabrics that are hard to seep out of charcoal powder. The sheet is divided into small sheets or SMS sheets and wrapped to form a charcoal sheet, and cut into fixed lengths, or a strip formed into a long strip is cut into a desired length to form a charcoal sheet. Form a sheet.

Further, as described above, a carbon fiber formed by carbonizing the fiber is formed into a sheet shape, which is used as a core material, and a nonwoven fabric or a woven fabric is disposed on the upper and lower surfaces thereof, and a quilting process is performed on the entire surface to form a carbon sheet. You can also.

As shown in FIGS. 3 and 5, a charcoal sheet is inserted into an outer bag of a futon size for a baby or a child, and is made into a cassette smaller than that of a conventional product, thereby facilitating attachment and detachment from bedding. This makes it possible to remove moisture absorbed by a sun dryer or a dryer, or to warm the bed with a kotatsu before going to bed to further improve the sleeping comfort in winter. In addition, by making one side of the bedding a warm material, it is possible to sleep without feeling cold even in the beginning of use in winter.

[0017]

[Examples] The specification of a coal powder-filled multiple sheet of this charcoal sheet is given as an example. One row in the horizontal direction has eight consecutive packages and the width of the sheet is about 540 millimeters. Size of one package is about 65 mm x about 80 mm (see Fig. 1C) c. It is around 6 grams per package of coal powder. The filling amount of this coal powder is the maximum amount that can be filled, and the effect of charcoal is great. The SMS sheet used in the present invention is a three-layered sheet in which a spun-pound nonwoven fabric (S) is arranged in a sandwich shape on a melt-blown fiber (M). Since the melt-blown fiber is ultra-fine and has low tensile strength, it is generally a composite. I'm using It is non-permeable and insulating, and has the property of having no air leakage and breathability.

Referring to the drawings, an embodiment of the present invention will be described. A charcoal sheet is made of charcoal or bamboo charcoal powder, granules or charcoal fiber having excellent effects such as far-infrared light, deodorization, humidity control, α-wave and negative ion. The raw material is divided into vertical and horizontal arrangements, and the film is laminated on the back of a thin spun-pound nonwoven fabric that does not easily leak carbon powder, wrapped in a sheet or SMS sheet with the required amount of holes with a needle, and this gap is welded. Then, it is used in the form of a continuous sheet or cut to a fixed size.

In the case of charcoal fiber, the charcoal fiber is formed into a sheet shape, and a nonwoven fabric and a cloth are laminated on both upper and lower surfaces to prevent the exudation of charcoal powder. A carbon sheet made of carbon fiber is formed by preventing the carbon fiber from shifting.

The thus formed charcoal sheet is appropriately laminated with various futon materials to form a baby futon-size small or three-fold large futon-size straight type cassette. Then, as shown in FIG. 5 or FIG. 6, it is inserted into the bedding (3) and used as it is. In FIG. 5A, three bags (4) are formed in the case of a baby futon-size cassette with respect to the bedding (3), and a charcoal sheet cassette is inserted therein. In FIG. 5 (b), one bag (4) is formed vertically with respect to the bedding (3), and a large straight type cassette is inserted into this to form a bedding (futon). In the figure, the bag is shown in a cylindrical shape, but may be a pocket-shaped bag having a mouth on one side. FIG. 6 is a cross-sectional view of the cassette, in which a lower layer is provided with a futon material such as cotton, feathers, wool, or polyester cotton, and a honeycomb-shaped woven or knitted material is provided on the upper surface. is there.

FIGS. 7 and 8 show a case where a charcoal sheet cassette is used as a core material and a futon material (5) such as woven fabric, nonwoven fabric, cotton, wool, or polyester cotton is laminated on the core material to form a bedding.
This stack may be an appropriate layer as shown in each figure.

FIG. 8 shows a structure in which a three-dimensional knitted fabric knitted in an uneven shape is further laminated on a surface layer of a bedding body (mat) into which a charcoal sheet cassette is inserted. This three-dimensional knitted fabric (6) is generally called a honeycomb-shaped woven knitted fabric and has high air permeability and extremely good texture, so it is not only preferred for summer use but also has an appropriate stimulus to prevent bedsores. There is. Further, although a honeycomb-shaped woven or knitted fabric is used on both sides in the drawing, one side can be used as a warm bedding for winter by using a thick cloth.

FIG. 9 shows an embodiment used as a nursing mat, in which various materials are laminated on a charcoal sheet shown in FIG. 1 or 2 and inserted into a bag with a chuck (5) for attachment and detachment. The cassette can be easily removed, and the outer bag can be easily removed and easily washed, so that the bag is always kept clean.

The charcoal sheet of the present invention is used as a coffin sheet. Conventionally, when the corpse was cooled with dry ice, there was a problem that water droplets condensed in the casket flowed out and the odor accumulated inside leaked out. Simply spreading and spreading a charcoal sheet or a mat with a simple cover on the bottom of the coffin can absorb 1-2 liters of moisture and off-flavors.

As the molded product using the charcoal sheet of the present invention, furniture such as a pillow, a car seat, a reception set, a kotatsu mat, a comforter, and an underlay in a refrigerator are provided in addition to a supporter as shown in FIG.・ Deodorants such as underlays, toilets, closets or shoe insoles in cars and clogs, as well as freshness-keeping supplies for perishables, paper diapers, diaper covers, bandages, casters, eye masks, and heat insulation It can be widely used for nursing and medical supplies such as vests.

In the present invention, the bedding such as a futon or a mat is formed for the charcoal cassette in FIG. 5 and FIG. 9, but the present invention is not limited to such a shape.
Needless to say, it can be used by overlapping with general bedding.

[0027]

As described above, since the bedding of the present invention uses a charcoal sheet, the odor and moisture are sufficiently adsorbed by the deodorizing effect and the moisture absorbing effect of the charcoal, and the refreshing feeling is maintained.

Further, the charcoal sheet of the present invention has a structure in which charcoal powder does not easily exude, so that it is unlikely to be stained black even when used for a long time.

Furthermore, since the molded article uses a honeycomb-shaped three-dimensional woven knitted fabric as a surface material, the skin feels comfortable and does not get out of bed even if a sick person or the like is used for a long period of time. Is obtained.

Since the present invention has the above-mentioned effects, it is also suitable as a bedding for nursing care. In this case, the outer cover of the bedding containing the charcoal sheet cassette is attached in a bag shape and a chuck is attached to the bedding. Since the take-out is easy, the outer skin can be easily washed and the cleanliness can be always maintained, which is very effective in nursing care.

Further, as shown in the embodiments, the charcoal sheet or cassette of the present invention uses various effects of charcoal to remove odors from pillows, car seats, reception sets, kotatsu mats, refrigerators and cars. It can be widely used for maintaining freshness of fresh food, etc.
