[Industrial applications]

 The present invention relates to a sleeping pillow material which has a long cool-keeping time by, for example, freezing water impregnated into a granular material and has an extremely excellent feeling in use.

[0002]

[Prior art]

 Conventionally, a so-called “ice pillow” in which ice water is stored in a rubber bag material has been used to cool the head at bedtime in a sick person or in summer. Since the "ice pillow" needs to be filled with ice water and water-tightly sealed with a fastener every time it is used, a pillow material in which a glycol-based liquid cold insulator is enclosed in a synthetic resin bag is widely used in recent years. ing. This pillow material can be used in the frozen state by storing the pillow material together with the pillow material in the freezer, and after the liquid cold insulating material is thawed, it can be frozen and used again as it is. .

[0003]

[Problems to be solved by the device]

 However, the pillow material encapsulating the liquid cold insulation material described above has a small amount of contact with the head surface when the head is placed during use, because the liquid cold insulation material freezes and hardens together. Become. Therefore, the user is not comfortable to sleep because only a part of the head surface is cooled, and the cooling effect is low, and part of it is extremely hard. Also, the pillow material with the liquid cold insulator frozen is too cold to directly contact the head and skin, or feels cold when wrapped with a towel etc. because it has too high heat insulation. It was extremely difficult to adjust the tactile temperature desired by the user. Furthermore, the frozen liquid cold insulator in this pillow material comes into contact with the air through the bag material, and the temperature is high especially in the summer and so on, so that it will thaw in a short time. That is, the cooling effect deteriorates and disappears in a short time. Further, the above-mentioned pillow material at the time of thawing was not useful because it did not have sufficient strength to support the head because the cold insulating material was a liquid.

[0004]

[Means for Solving the Problems]

 The present invention has been proposed in view of the above, and relates to a sleeping pillow having a large number of continuous fine voids and containing a granular material containing water in the fine voids in a bag material. .

[0005]

[Action]

 Since the sleeping pillow of the present invention has the above-mentioned structure, when it is stored in the freezer, the water in the fine voids of the granules freezes, but the granules do not aggregate and become integrated with each other as before the freezing. being independent. Therefore, when the head is placed during use, it deforms according to the pressure of the head, and a large area comes into contact with the head to provide a cooling effect. In addition, since the water (frozen ice) in the granules exists inside the microscopic voids, the coldness adjusted to a moderately cool tactile temperature is transmitted to the head and skin through the granules. . In addition, the granules themselves perform a heat insulating function that prevents contact between water (frozen ice) in the granules and the air, so that the cooling effect continues for a long time. In addition, even if the water in the granules is not frozen, there is no problem in using it as a normal pillow.

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments of the drawings.

As shown in FIGS. 1 and 2, a sleeping pillow material 1 of the present invention contains a large number of granular materials 2 ... In a bag material 3. The granular material 2 has a number of continuous fine voids 21. And the water 4 is present in the fine voids 21.

The granular material 2 used in the present invention is not particularly limited as long as it is an inorganic material or an organic material as long as it has continuous fine voids 21. It is desirable to have hardness (deformation strength) that does not press the fine voids 21 and strength (cohesive strength) that does not crush the micropores 21 during use. For example, activated carbon or the like can be used. Further, the above-mentioned granular material 2 is usually used having a particle size of about 0.5 to 10 mm, but it is not particularly limited to the above range, and may be appropriately selected according to the feel of the sleeping pillow material 1 when used. Just set it.

Although the water 4 is allowed to exist in the fine voids 21 of the granular material 2, the water 4 may be adsorbed in the fine voids 21 by utilizing a capillary phenomenon, or the water 4 may be absorbed in the fine voids 21. The material 2 may be dipped to apply vibration or ultrasonic waves to expel the air in the fine voids 21 to adsorb the water 4 into the fine voids 21. In particular, the treatment method is not limited. Absent.

Further, the bag material 3 for accommodating the above-mentioned granular material 2 is not particularly limited in its material, thickness, shape, etc., but is flexible, and temporarily, inside the fine voids 21 of the granular material 2. Even if the water 4 flows out from it, it is desirable that it has a water-blocking property such that it does not leak to the outside, and that it has a strength that does not deform or break due to the contact of the granular material 2, for example polyethylene (PE) A general-purpose plastic film such as polypropylene, polypropylene (PP), or polyethylene terephthalate (PET) can be used, or a non-woven cloth, cloth, or soft paper coated or laminated with a resin can be used. it can.

[0011] Furthermore, a pillow cover (not shown) may be attached to the surface in the same manner as a normal pillow to improve the feel of the skin. Further, an elastic body such as a sponge may be laminated on the lower surface side thereof to give a feeling of elasticity, or a pillow cover-like structure may be formed so as to be integrally attached to a normal pillow, Any other configuration can be added.

Since the sleeping pillow 1 of the present invention has the above-mentioned configuration, it does not cause any trouble even if it is used as it is, and the water 4 in the fine voids 21 does not escape due to the capillary effect. Moreover, when the water 4 in the granules 2 freezes when stored in a freezer or the like, it gives an extremely excellent usability and cooling effect compared to conventional "ice pillows" and pillows that store liquid cold insulators. Will be things.

For example, in the past, ice water or ice (frozen liquid cold insulation material) was stored as a refrigerant, so the feel when the head is placed is completely different from that of an ordinary pillow, and especially the head is tilted. Although it felt uncomfortable each time, the sleeping pillow 1 of the present invention stores the granules 2 which are independent of each other without being integrated even after freezing, so that the sleeping pillow 1 can be used as a normal pillow. Gives a similar feel.

Further, conventionally, ice water or ice (frozen liquid cold insulation material) is in direct contact with air (via the bag material), so that the cooling effect is reduced or disappears in a short time. Since the granular material 2 itself fulfills the heat insulating function of preventing contact between the water 4 (frozen ice) in the fine voids 21 and the air, the cooling effect is continued for a long time.

In particular, when activated carbon is used as the granules 2, the activated carbon adsorbs moisture and odor, and pests such as mites hardly adhere to the granulated material 2, so that the pillow has a comfortable odor and stuffiness. It is also effective in recovering from fatigue.

The present invention has been described above based on the embodiments of the drawings, but the present invention is not limited to the above embodiments, and as long as the configuration described in the scope of claims for utility model is not changed, But it can be done.

[0017]

[Effect of device]

 As described above, the sleeping pillow of the present invention has a cooling effect by freezing the water in the fine voids of the granule when it is stored in the freezer or the like like the conventional pillow that stores the liquid cold insulator. Will be things. Moreover, since the granules in the present invention are independent of each other as they are before freezing without being aggregated and integrated, when the head is placed during use, it is deformed according to the pressure of the head and a large area is obtained. Touches the head and gives a cooling effect.

Further, since the ice frozen in the fine voids of the granular material comes into contact with the head and the skin through the granular material, the coldness of the tactile temperature desired by the user can be transmitted.

Further, since the granular material itself has a heat insulating function of preventing contact between ice frozen in the fine voids and air, the cooling effect (cooling time) is continued for a long time.

Therefore, the sleeping pillow of the present invention can efficiently cool the head of a sick person who has a high fever, or gives a cool feeling to the user even in a tropical night in the summer, so that the sleeping pillow is comfortable for a long time. It will provide a good night's sleep.

In addition, the sleeping pillow of the present invention gives a feeling of use similar to that of a normal pillow even when the water in the fine voids is not frozen, and therefore its utility value is extremely high.
