DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a health pillow having healthy and comfortable sleeping conditions.

[0002]

2. Description of the Related Art Various types of pillows have been proposed and marketed so far as they relate to sleep and health. In general, pillows filled with cotton, buckwheat husk, various fibers and chips, sponge, etc. are often used inside the bag, but cushions, air permeability, heat dissipation etc. are important conditions for pillows. Therefore, many improvements have been made not only to the material of the filling but also to the shape and structure.

By the way, recently, research on charcoal has progressed,
Since its utility has been clarified, it can be used for other aspects of life other than fuel. Charcoal is not only excellent in air permeability, high dehumidification and deodorization effect, but also has negative ion generation and electromagnetic wave shielding performance, and can be expected to have a favorable effect on life and health. The use of is being promoted.

As a pillow using charcoal, conventionally, pillows shown in FIGS. 5 to 7 have been proposed or marketed. The pillow shown in FIG. 5 has a bag 7 filled with only charcoal granules 3 obtained by crushing charcoal, and a bag 8 filled with cotton, buckwheat husk, sponge, granular wood pieces, etc., which has been conventionally used as a pillow filling.
Are put in the outer bag 10 by overlapping. The pillow of FIG. 6 is a flat bag in which several cylindrical bags 11 packed with charcoal granules 3 are connected, and fillings 13 such as wood chips are inserted at both ends.
As shown by the dashed line in the figure, the cylindrical bags 11, 11 are sandwiched between the flat bags 12, 12, and are used. In the pillow of FIG. 7, a stick-like charcoal 14 is placed in a cylindrical bag 15 and a conventional filling 9 similar to the above is arranged around the cylindrical bag 15 to form an outer bag 10.
It was put in.

[0005]

When charcoal is used as a filling for a pillow, it is ideal that the whole filling is charcoal in view of the effect of charcoal. However, charcoal is quite hard and has a severe contact with the head and the like, and charcoal has a much higher specific gravity than the conventional pillow filling, so it is too heavy as a pillow and handling is troublesome. Therefore, a pillow filled only with charcoal lacks practicality.

[0006] Therefore, it has been considered to mix the charcoal granules with other materials to form a pillow filling. In this case, since it is necessary to utilize the effect of charcoal, other materials mixed with charcoal are considerably limited, such as buckwheat hulls, wood chips, and various chips. In addition, since charcoal has a relatively large specific gravity with respect to other mixed materials, the charcoal grains separate from other materials during use, and the charcoal grains settle down, separating from the head, and the effect of using charcoal is obtained. Will not be. Therefore, a pillow using charcoal has a structure in which charcoal and other materials are separately packed in a bag and combined and connected as shown in FIGS.

However, these conventional charcoal pillows using charcoal are complicated in structure, cumbersome to manufacture and use, and costly.
It has problems such as the inability of charcoal to exhibit its full potential. In particular, the pillow shown in FIG. 5 is characterized in that a flat bag is packed with spherical chips of wood having insect and fungicide effects, and is used in combination with charcoal. In addition to the poor cushioning properties, the contact of the wood chips is strongly felt on the head and is unsuitable as a pillow for obtaining sleep.

The present invention has been made in view of the above circumstances,
This was made to solve the drawbacks of conventional pillows using charcoal, and a mixture of charcoal grains was used as a mixture with charcoal grains. Is intended to provide a health pillow which can be used stably without causing separation, obtains a suitable cushioning property as a pillow, is inexpensive, has a high level of sleep and is excellent in health effects, and a method for producing the same. Is what you do.

[0009]

The constitution of the present invention for achieving the above object will be described with reference to the embodiment shown in the drawings. The health pillow of claim 1 is a charcoal crushed to a required size. The filling 2 formed by mixing the grains 3 with a piece of wood 4 formed into a curl larger than the charcoal grains is filled in a bag 1 made of air-permeable cloth.

According to a second aspect of the present invention, there is provided a method of manufacturing a health pillow, wherein a wood without a skin is cut using a plane blade 5 having a non-cutting portion 6 at a required interval in a width direction. Wooden piece 4
The cut wood pieces 4 are mixed with the charcoal grains which have been crushed to a required size and then dried, and the mixture is filled to form a bag 1 made of air-permeable, closed cloth. It is characterized by filling.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the pillow of the present invention, FIG. 2 shows a wooden piece cut in a curl shape, and FIG.
Fig. 4 shows an example of a mixed state of the filling of the pillow. Fig. 4 shows an embodiment of a plane blade for cutting curled wood chips. The pillow of the present invention is formed by filling a mixture of charcoal granules and a piece of curled wood and filling the bag with the filler.

[0012] Charcoal is a carbonized product of wood, and is known as a carbonaceous polymer containing hydrogen, oxygen and various minerals in addition to 80% carbon, and is porous and has a pore surface area of 300 m ² / g. , Breathable and dehumidifying,
Excellent deodorization. The types of charcoal are broadly classified into white charcoal and black charcoal. White charcoal is known for its high hardness and high quality, and black charcoal is softer than white charcoal and is most commonly produced.

[0013] The charcoal used in the present invention may be white charcoal or black charcoal, but preferably white charcoal is harder to be powdered even if used for a long period of time because of its higher strength, and white charcoal generates negative ions and emits far infrared rays. Due to its properties, it has many practical and health advantages over black charcoal, making it more suitable as a material for pillows. Charcoal is obtained by crushing charcoal (charcoal sticks or the like) discharged from a kiln into small particles using a crusher or the like to obtain charcoal particles. In this case, charcoal powder is also produced, so that the charcoal particles having a particle size of about 3 to 7 mm are taken out and used.

In the present invention, the wood chips mixed with the charcoal granules have a shape that can be uniformly mixed and maintained for a long time, in addition to the effect of woody properties, as well as the cushioning and breathability of the pillow filling. It is necessary to be formed in a large size and to be mass-produced at low cost. The wood used as the material for the wood chips is selected from those that have insect repellency and mold resistance, are lightweight, and have high elasticity. For example, hinoki, hiba, cedar, paulownia, hono-ki, etc. are suitable. And a piece of wood is obtained by processing the above wood.

As shown in FIG. 2, the shape and size of the piece of wood are such that the thin plate is bent in a curl shape as shown in FIG. 2, and the width L is 15 to 30 mm and the diameter D is 6 to 6. Ten
It is preferable to set it to about mm. It is advisable to process the wood piece 4 using a rotary plane machine. in this case,
Use a special plane blade. That is, for example, as shown in FIG. 4, the plane blade used for the non-cutting portion 6 such as a notch portion is provided at a required interval in the width direction of the plane blade 5 at the edge of the plane blade 5. Use the plane blade 5 provided. In such a case, the wood is cut into a plurality of strips having a width L corresponding to the above-mentioned interval while being curled.

Further, in this cutting, the wood cut in a strip shape is automatically cut into required lengths as shown in FIG. I will make it bend in the length direction. For that purpose, it is important to select the protruding length of the blade edge of the plane blade 5. If the protruding length of the cutting edge is small, the strip-shaped material will be continuously cut with a small thickness, and will be too soft as a filling. On the other hand, if the protruding length of the cutting edge is too large, it will be cut into a fine chip shape.
In this regard, many experiments have been repeated on various types of wood. As a result, the protrusion length of the cutting edge is 1 to 5 mm depending on the type of wood to be applied and the size of the curl of the piece of wood to be cut. It was found that it was better to select within the range. In the case of cypress or wood of a material similar thereto, it is particularly preferable that the protruding length of the cutting edge is 1 to 3 mm.

The charcoal grains 3 are washed and dried, and the water is completely removed and mixed with the wood chips. For mixing, for example, a rotary drum type mixer is used. Thereby, as shown in FIG.
The charcoal grains 3 penetrate into the curled wood pieces 4 or penetrate between the wood pieces to be embraced and sandwiched by the wood pieces, and to mix uniformly and in a state where they are hard to separate from each other. Note that, in FIG. 3, in order to make the mixed state of the charcoal grains 3 and the wood pieces 4 easy to understand, the wood pieces are shown aligned in the same direction, but actually, the wood pieces 4 are irregularly overlapped. The charcoal grains 3 are in a state of being mixed in and between the wood pieces 4.

The pillow filling 2 is made by mixing the charcoal grains 3 and the wood pieces 4. In such a filling 2, the elasticity of the curled wood piece and the hardness of the charcoal grains are combined, so that an appropriate cushioning property as a pillow filling can be obtained. The mixing ratio between the charcoal grains 3 and the wood pieces 4 is determined in consideration of the weight and cushioning properties of the filling and the properties of the charcoal grains and the wood pieces. It is better to set the ratio. In addition, with this mixing ratio, a result was obtained in which uniform mixing was possible and separation of the two was unlikely to occur.

The pillow bag 1 to be filled with the filling 2 is made of a cloth which is air-permeable, has tight eyes, and is hardly permeated when the charcoal grains are powdered. is necessary. For example, breathable non-woven fabric or cotton,
It is better to use silk, linen, or other dignified fabric. The bag 1 can have any shape. The shape of the bag 1 shown in FIG. 1 is a flat rectangular shape, but is not limited to such a shape.

As described above, the pillow of the present invention uses a filling mixture of charcoal granules and curled wood chips, so that the pillow has appropriate elasticity required for the pillow and has good air permeability. In addition, the separation and sedimentation of the charcoal particles hardly occur, and the characteristics of wood such as charcoal and cypress can be directly utilized. In other words, charcoal has moisture absorption and dehumidification functions, so it absorbs odors, harmful substances and impurities in the air,
Decomposes it to help deodorize and clean the air, and has the performance of shielding electromagnetic waves and radiating far-infrared rays, and at the same time, the contained minerals and negative ions are taken into the human body to promote blood circulation. Will have a positive effect on the human body. In addition, wood that uses hinoki, in particular, has high resistance to pests and insects, exhibits a repellent function, has a good aroma, and provides a hygienic and comfortable sleep.

[0021]

As described above, according to the present invention,
Both charcoal grains and curled wood chips were mixed with a material with good air permeability and filled into a breathable closed cloth bag, so the characteristics of the charcoal particles and the characteristics of the wood chips Thereby, it is excellent in moisture absorption and dehumidification properties, and can always maintain an appropriate dry state, and has a deodorant and insect repellent function. It is sanitary because it eliminates bad odors and does not attract insects such as mites and lice. In addition, it absorbs body sweat, body odor, etc., regulates humidity, and also shuts off electromagnetic waves, does not carry static electricity, allows you to always sleep in a refreshing sensation, and has an extremely excellent effect on maintaining health.

Further, by mixing the charcoal grains and the curled wood pieces, the pillow has a moderate cushioning property and excellent air permeability required for the pillow, and the charcoal grains are uniformly held by the wood pieces themselves or between the wood pieces. The charcoal grains are less likely to separate and separate from the wood pieces during use, causing less sedimentation and skew.The pillow has a simple structure, and is easy to manufacture and suitable for mass production. , Can be provided at low cost.
