DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, in which 1 is a pillow according to the present invention, and the pillow 1 has a cooling function section 3 and a far infrared radiation function section 4 on one side 2 and 2a, respectively.
In addition, the pillow cover 6 is surrounded and surrounded by a batting 5 made of cotton, polyester, or a synthetic fiber such as a mixed spinning of these, interposed between the functional portions 3 and 4.

The cold insulation function portion 3 is formed by surrounding a buffer body 7 made of an elastic material such as urethane foam with a cover body 8 made of vinyl chloride, and the entire upper surface of the cover body 8 is shaped like a flat bag. The cold-retaining agent holding portion 10 is formed by injecting and sealing the cold-retaining agent 9 described later.

The buffer body 7 is formed by forming the base 11 into a rectangular parallelepiped having a predetermined thickness and an area substantially corresponding to one surface of the pillow 1, and a quadrangular pyramidal convex portion 12 having a predetermined height is formed on the entire upper portion of the base 11. A large number of inverted quadrangular pyramidal recesses 13 are provided alternately to form a pressure receiving portion 14 having a wavy cross section.

It should be noted that the pressure receiving portion 14 provided on the buffer body 7 has a plurality of quadrangular pyramid-shaped convex portions 12 and inverted quadrangular pyramid-shaped concave portions 13 alternately provided, but the invention is not limited to such a system, and the conical Shape, triangular pyramid, other polygonal pyramid, columnar, quadrangular prism, triangular prism, or other prism-shaped convex portion 12 or an inverted concave portion 13 thereof may be formed. Any structure may be used as long as a space can be held between the convex portions 12 even if the convex portions 12 are contracted so as to be crushed by the heavy pressure applied when the head is placed on the cold insulating agent holding portion 10.

In addition, the cold-retaining agent holding portion 10 welds and seals the peripheral portions 16 of the upper and lower two sheets 15 and 15a formed on the upper surface portion of the cover body 8 and at a predetermined number in the vertical and horizontal directions of the sheets 15 and 15a. The circular joint portions 17, 17a ... Are welded and arranged at a predetermined interval.

Cooling agent 9 is mainly composed of sodium sulfate decahydrate (Glauber's salt) consisting of sodium sulfate and water.
Glauber's salt has a melting temperature of about 32 ° C. and about 50 to 60 cal / g.
It has the heat of fusion of and is a long-term heat storage (endotherm) as a refrigerant.
In order to maintain a stable cycle of heat dissipation, it is necessary to control the crystallinity, crystal diameter, and melting point, so it is necessary to select the solution concentration and additives and mix them appropriately.
As additives, silicon fibers and a crystal accelerating agent such as sodium borate, magnesium chloride, sodium chloride, etc. are used, and it is possible to increase the crystal size and the dispersibility to withstand long-term use. % By weight, 66% by weight of water, 2% by weight of silicon fibers, and 2% by weight of a crystallization accelerator are mixed to form a cold insulating agent 9 at room temperature (about 18% by weight).
(Degrees to 25 ° C.), the sherbet state is maintained by minute crystals.

In the present embodiment, the joining portions 17, 17a of the cold-retaining agent holding portion 10 are formed by welding and arranging a predetermined number of circular ones in the vertical and horizontal directions, but the invention is not limited to such a method. Instead, they may be welded in a triangular shape, a quadrangular shape, or another polygonal shape, or may be welded in parallel linear shapes as shown in FIG. 7.

The far-infrared radiation function section 4 is made of far-infrared radiation ceramic kneading specially processed fibers. The ceramic powder is kneaded and processed into synthetic cotton such as polyester, acrylic, polypropylene, rayon, etc. to form a cotton-like flat plate. It is formed into a shape, and the ceramic is alumina,
Zirconium, or a material having a far-infrared radiation effect higher than that of sintered alumina and silica, to which colloidal platinum is added as a main component, or sintered alumina and silica as a main component, to which colloidal platinum and silicon nitride are added. I'm using one.

In this embodiment, the pillow 1 is made of batting 5.
Although the cold insulation function part 3 and the far-infrared radiation function part 4 are provided via the above, the pillow 1 may have the same configuration as the cold insulation function part 3.

Next, the operation of the functional pillow according to the present invention will be described. The pillow 1 is used with the cold insulation function portion 3 side facing upwards depending on the preference of the user, or in the summer or when heat is generated, and the neck or neck. When fatigue such as stiffness of the shoulder is felt, the far-infrared radiation functioning part 4 is used with the side up, and the functioning parts 3 and 4 will be described in detail below.

When the cold insulation function part 3 is used upward, the cold insulation 9 in the cold insulation holding part 10 is at room temperature (about 18 to 25 ° C.).
Then, in the state where it solidified into a sherbet,
When the head is placed on the head, such a portion is depressed by the heavy pressure of the head, and the convex portion 12 of the pressure receiving portion 14 in the buffer 7 contracts due to the elastic action, but is not completely crushed and becomes flat. A space S is held between them.

Then, the cold insulating agent 9 corresponding to the portion on which the head is placed is melted and liquefied by the influence of the body temperature, and the liquid cold insulating agent 9 is applied to the other portion which is not pressed by the heavy pressure of the head,
That is, it flows to the solidified portion, and the entire cold insulating agent 9 is liquefied.

When the cold insulating agent 9 is melted, the cold insulating agent 9 absorbs the temperature of the head and cools the head.

Further, since the cold-retaining agent holding portion 10 under the heavy pressure of the head holds the space S between the respective convex portions 12 of the buffer body 7 as described above even when the cold-retaining agent 9 is liquefied, it is completely Since it does not crush and has a bulge that holds the ice pack 9, the ice pack 9 is constantly present under the head, and the liquefied ice pack 9 can flow in the whole ice pack holding portion 10. It is in.

[0019] Then, the cooling agent holding portion not in contact with the head
Since the cold-preserving agent 9 in 10 is lower than the body temperature and is in a cooled state, the cold-preserving agent 9 in such a portion radiates heat, gradually crystallizes and solidifies, and flows in the cold-preserving agent holding portion 10.

As described above, the cold insulating agent 9 flows and circulates in the cold insulating agent holding portion 10 while repeatedly melting by heat absorption at the portion on which the head is placed and coagulating by heat radiation at other portions, and thus, the head Keep it at about 5-10 ° C below body temperature.

Further, the silicon fibers mixed in the cold-preserving agent 9 not only increase the viscosity of Glauber's salt, which is the main component, but also disperse the sodium sulfate and water evenly so as not to separate them. By making it as small as possible to promote melting and solidification, the efficiency of the cycle of melting by heat absorption of the heat insulating agent 9 and solidification by heat radiation is achieved.

When the far-infrared radiation functioning part 4 is used upward, the ceramic kneaded in the far-infrared radiation functioning part 4 is heated at body temperature, and due to its material characteristics, the far-infrared radiation (wavelength 6) is emitted from the ceramic. ~ 14μ) is efficiently radiated.

[0023]

In summary, according to the present invention, a buffer 7 having an elastic action is provided with a pressure receiving portion 14 having a wavy cross-section, and a sodium sulphate and water are added to the pressure receiving portion 14 with a silicon fiber and a crystallization accelerator. Cooling agent holding part in the shape of a flat bag in which 9 is injected and sealed
Since 10 is arranged, the cooling agent 9 on the part on which the head rests during sleep is melted and liquefied due to the effect of body temperature due to its material characteristics, and at this time, the part of the head under heavy pressure is buffered 7 Even if the convex portion 12 of the pressure receiving portion 14 in FIG. 2 elastically contracts, the space S can be held between the respective convex portions 12, so that even when the cold insulating agent 9 is liquefied, the cold insulating agent holding portion 10 that is under heavy pressure on the head is used. Is not completely crushed, has a bulge that holds the ice pack 9, and the ice pack 9 is constantly present under the head, and the liquefied ice pack 9 can flow in the whole ice pack holder 10. Cooling agent 9 in the cooling agent holding portion 10 which can be made
Is lower than the body temperature and is in a cooled state, so that the ice pack 9 in such a portion radiates heat to gradually crystallize and solidify, and can flow in the ice pack holding portion 10, and thus the ice pack holding portion.
Cooling agent 9 in 10 is melted by heat absorption at the part where the head is placed,
By repeatedly flowing and circulating in the cold-retaining agent holding portion 10 while repeatedly solidifying by heat dissipation in other parts, the head can be kept cold at a temperature which is always about 5 to 10 ° C. lower than the body temperature. Since it is the optimal condition for sleep, it can promote deep sleep and induce a restful sleep to recover from fatigue, and it is more effective at a suitable cold temperature than a water pillow or ice pillow that loses its cooling function over time when a fever occurs. Since it is possible to cool the part, and since it is not necessary to cool it in the refrigerator, it is possible to cool the head even in the event of an emergency, and it is possible to eliminate insomnia and sleep well even in a sleepy environment such as in the summer.

Further, since the cushioning body 7 receives the head with a moderate softness due to its elastic action, it is well familiar and can sleep without burdening the shoulders and neck.

Further, according to the present invention, as described above, the portion of the cold-retaining agent holding portion 10 which is under the heavy pressure of the head is not affected even if the convex portion 12 of the pressure receiving portion 14 of the buffer body 7 is elastically contracted. Since the space S can be held between the two, the cold insulation agent 9 in the solidified or liquefied state constantly exists under the head, and the cold insulation agent holding portion of the cold insulation agent 9 is present.
It is possible to flow the entire inside of the cooler 10, thereby maintaining the cooler function of the cooler 9 as described above. For example, in a pillow in which the cooler holder 10 is simply placed on synthetic cotton, the cooler holder is used. When the head is placed on the head 10, since such a portion cannot hold the liquefied ice pack 9 which is completely crushed by the pressure of the head, it is biased to the portion of the ice pack holding portion 10 where the head is not placed, It is not possible to cool the part, and moreover, the ice pack 9 cannot flow in the whole ice pack holding part 10, so the cycle of heat absorption and heat release cannot be performed, and it is not possible to keep it cold, or the use of synthetic cotton in the pillow is reduced by use. When the pillow is deformed, the cold storage agent holding portion 10 cannot be maintained horizontally, so that the cold storage agent 9 solidifies in a biased state during storage of the pillow, and it is possible to eliminate an irrational possibility that it may hinder use.

Further, as the ice-reserving agent 9 is made of sodium sulfate and water alone, the salt is separated and only the lower layer is crystallized, and the desired ice-retaining effect cannot be expected. Along with increasing the viscosity, sodium sulfate and water are evenly mixed, the dispersibility of the crystals can be increased and the whole can be crystallized uniformly, and by mixing a crystal promoter, the diameter of the crystals can be reduced, The heat of fusion can be melted faster than the body temperature and can be radiated more quickly, promote the melting and solidification, and improve the efficiency of the heat absorption and heat dissipation cycle of the cold insulation agent 9, and fully exert the cold insulation function of the cold insulation agent 9. Can be done.

Further, the buffer 7 having an elastic action is provided with a pressure-receiving portion 14 having a corrugated cross section, and the cold-retaining agent 9 in which silicon fiber and crystallization promoter are added to sodium sulfate and water is injected and sealed on the pressure-receiving portion 14. A flat bag-shaped cold-retaining agent holding portion 10 is arranged to form the cold-retaining function portion 3, and a ceramic is kneaded into synthetic cotton to be formed into a cotton-like flat shape to form a far-infrared radiation function portion 4. Since the batting 5 is interposed between both the functional parts 3 and 4, the pillow 1 can have different functions on each of the one side 2 and 2a, and the user can adjust his / her preference or physical condition to the situation. Therefore, for example, in the summer or when heat is generated, the cold insulation function part 3 side is used up, and when fatigue such as stiffness in the neck or shoulder is felt, the far infrared radiation function part 4 side is used up and two You can use different functions.

On the side of the cooling function section 3 of the pillow 1,
The same effects as described above can be obtained, and since the far infrared radiation function part 4 is made by kneading and processing the ceramic into the synthetic cotton, the ceramic is less likely to come off than the one to which the ceramic is simply attached. Since far infrared rays can be reliably emitted from each fiber without being used, the radiation efficiency of far infrared rays can be improved, and the ceramics of the far infrared radiation function part 4 are warmed to the body temperature, which is effective for the human body from the ceramics. Far-infrared rays (wavelength 6-14μ) are efficiently radiated, and such far-infrared rays penetrate the skin, expand capillaries, improve blood circulation, improve blood circulation, and activate cells. It promotes metabolism, relieves muscle tension from head to shoulder during sleep to recover from fatigue and can maintain normal sleep, especially in winter when bed is cold. But I can sleep warmly and comfortably.

In addition, the cold insulation function section 3 and the far infrared radiation function section 4
By interposing a batting 5 between the and, it can be used without any discomfort as it is a normal pillow, and the far-infrared radiation function section 4 side has a good feel and provides a good night's sleep. It is possible to prevent the far-infrared radiation function of the far-infrared radiation function section 4 from affecting the cold insulation function section 3.

Further, a predetermined number of joining portions 17, 17a in the vertical and horizontal directions of the upper and lower two sheets 15, 15a constituting the cold-retaining agent holding portion 10.
Since the melt deposits are arranged at a predetermined interval, if the pillow 1 is in a horizontal state, the liquefied or crystallized ice pack 9 can be evenly dispersed, and even if the ice pack 9 solidifies, the ice pack holder 10 It is possible to prevent biasing to a certain portion, and it is possible to improve the efficiency of the cycle of heat absorption (melting) and heat dissipation (solidification) by the cold insulating agent 9.

Further, since the cold-preserving agent holding portion 10 is integrally formed with the cover body 8 which surrounds and covers the buffer body 7, it can be prevented from being displaced from the buffer body 7 while the pillow 1 is in use. Its practical effect is extremely great, such as being able to maintain the cooling effect.
