Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a pillow.

Conventional pillow types include ordinary pillows, water pillows, and special pillows that use a cold storage material. An ordinary pillow has buckwheat hulls, a synthetic resin pipe-shaped object, a panya, a blade, etc. as its inner material.

[0003]

In the above-mentioned conventional pillow, the heat of the user's head is transferred to the middle material of a normal pillow, the water of a water pillow, or the cold storage material of a special pillow, and between them. Although there is a difference in time, the temperature of the surface that supports the head increases due to the accumulation of each. In ordinary pillows, particularly in the case of high temperature and humidity such as summer, sleep is disturbed and the cooling function of water pillows and special pillows disappears in a short time.

In view of the above, the present invention quickly diffuses the heat accumulated in the pillow to prevent the pillow temperature from rising.
It is intended to provide a comfortable sleep and a long-term retention of cooling function.

[0005]

In order to achieve the above object, the present invention provides a heat dissipation material on the surface of a pillow that directly or indirectly supports the head, and quickly dissipates the heat accumulated in the pillow by the heat dissipation material. It is configured to spread.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below with reference to the drawings.

FIGS. 1 and 2 show a pillow (1) of the first embodiment. This pillow is an intermediate material (2) integrally molded with a foam such as urethane foam having an appropriate cushioning property. When,
The regenerator (4) incorporated in the recess (3) formed on the upper surface of this middle material, and these middle materials (2) and regenerator (4)
It is composed of a pillow cover (5) for covering.

The regenerator (4) comprises a regenerator material (6) and a bag (7) covering it. As the cold storage material (6), a material formed into a pudding shape with a polyacrylic acid acrylate copolymer copolymer, a water-absorbing polymer or the like is preferably used. When these cold storage materials (6) are used in a natural state without being actively cooled in the freezer, the cold storage materials are slightly lower than room temperature (about 1 to 5 ° C. below room temperature) and give a soft touch. Since it is about the extent, it is kept at least at room temperature without cooling the head more than necessary like a water pillow. This invites a good night's sleep and maintains a comfortable sleep.

The bag (7) covering the cold storage material (6) is made of synthetic resin such as soft polyvinyl chloride. This bag is provided with a heat dissipation member (8) made of a material having a good thermal conductivity, such as metal, on the upper surface (the surface supporting the head). Aluminum powder is preferably used as the heat dissipating material (8), and this powder is laminated on the bag in a continuous pattern in a mesh by a printing means. This heat dissipation material (8)
Diffuses the heat transferred from the head to the cold storage material (6) and dissipates it into the atmosphere. As a result, the temperature rise of the cold storage material (6) is delayed, the usable temperature time is significantly improved, and a comfortable pillow can be obtained.

In the pillow having the above-mentioned cool storage material (6), the heat storage material (6) with or without the heat dissipating material (8) on the upper surface has a predetermined surface temperature below the cool storage material (4). The results of comparison of the time required for the rise are shown in Table 1 below.

[0011]

[Table 1]

In Table 1, PVC indicates polyvinyl chloride and AL indicates aluminum. As the heating means in the comparative test of Table 1, a heating surface having a square shape of 15 cm × 15 cm and a weight of 5 kg is used, and the heating means is cooled through a lace-shaped cover (5). It was placed at the center of the upper surface of the body (4) and the temperature of the center of the lower surface of the regenerator (4) in contact with the middle material (2) was measured.

As is apparent from Table 1, the effect of the heat radiating material (8) on the regenerator (4) is that the time required to reach a predetermined temperature is 23% to 38% longer, and the temperature of the regenerator (6) is higher. It has been found to slow the rise and significantly improve its service temperature time. The heating temperature is 35 ℃ to 39 ℃.
What was measured over time corresponded to the human body temperature.

The regenerator (4) may be used after being actively cooled in a freezing room, a refrigerating room or a cooler, if necessary.

In order to confirm the heat diffusion effect of the heat dissipation material (8), the following comparative test was conducted. As a test body, in a soft polyvinyl chloride bag (size of a normal pillow inner bag),
Filled with water and applied to the net-shaped cloth in the same manner as in Table 1.
The aluminum powder is heated by a heating means (the same as in the case of Table 1) through the one which is laminated in a mesh pattern by the printing means and the one which is not laminated by the printing means, and the surface temperature below the water bag is kept at a predetermined level. The time required to raise the temperature was compared. The comparison results are shown in Table 2 below.

[0016]

[Table 2]

In Table 2, PVC indicates polyvinyl chloride and AL indicates aluminum.

From Table 2 as well, similar to Table 1, the effect of the heat dissipation material (8) on water as the inner material of the pillow is as follows.
It has been found that the predetermined time is increased by approximately 50%, delaying the temperature rise of the water and significantly improving its usable temperature time. From this, it can be inferred that even if this heat dissipation material (8) is used for an ordinary water pillow, a similar effect can be expected.

The heat radiating material (8) is applied to the pillow (9) which has been generally used in the past, in addition to the regenerator (4) and the like. An example thereof is shown in FIGS.

This pillow (9) is made of short pipe-shaped middle material (10).
And a pillow bag (12) covering the inner bag (11) and the inner bag (11).

The intermediate material (10) is made of a short polyethylene pipe (diameter 3 to 10 mm, length 5 to 10 mm),
No pests are generated, it is hygienic and has good elastic cushioning.

The inner bag (11) is a synthetic resin sheet in which a polka dot pattern is removed to form a continuous pattern in all directions. The inner bag (11) is provided with a heat dissipating material (13) similar to the heat dissipating material (8) of the above-mentioned embodiment on the upper surface thereof.

This heat dissipating material (13) is also laminated on the inner bag (11) by a printing means in a continuous pattern on all sides in a polka dot pattern. This heat dissipation material (13) also diffuses the heat transferred from the head to the middle material (10) of the pillow and dissipates it into the atmosphere.
As a result, the temperature rise of the middle material (10) is delayed, the usable temperature time is significantly improved, and a comfortable pillow is obtained.

As a method of disposing aluminum powder as the heat dissipating material (13) on the surface of the support pillow directly or indirectly with the head by a printing means, the heat dissipating material (13) is formed in a continuous pattern in all directions. It is extremely easy to do so, and the heat radiation material is firmly attached to the pillow due to its continuous pattern and there is no danger of peeling, but as another method, aluminum powder is sprayed by coating means or vapor deposition by vapor deposition means. Alternatively, aluminum foil can be attached with an adhesive. In addition, heat dissipation material (8),
In addition to the bag (7) for the cold storage material (6) and the inner bag (11) for the pillow inner material (10), (13) is also a bag for pillow covers (5), (12) and water pillows. Etc., and may be provided not only on one side of those bags but also on both sides, or on the back side in addition to the front side. As the inner material (10) of the pillow, buckwheat hulls, panya, feathers, etc. can be used.

[0025]

The pillow of the present invention is a cover for a pillow (5, 12).
, Pillow middle bag (11), cold storage bag (7), water pillow bag, etc. on the surface that directly or indirectly supports the head, using a material with good thermal conductivity such as metal. Since the formed heat dissipation material (8, 13) is provided, the heat accumulated in the pillow is quickly diffused to prevent the temperature rise of the pillow, resulting in comfortable sleep and long-term maintenance of the cooling function. . According to the present invention, since the heat dissipating material (8, 13) is formed in a continuous pattern such as a mesh pattern or a dot pattern, the heat dissipating material (8, 13) does not come off from the laminated surface and is firmly attached.
