Description

The present invention relates to a cooling pillow having a function of cooling the head, which is used when a person goes to bed.

In the hot summer months, it is difficult to sleep, and when the temperature of the pillow that is in contact with the head, which has a large amount of heat, rises, it becomes more difficult to sleep, so it is often impossible to sleep soundly. In order to solve such a problem, various pillows having a function of cooling the head while sleeping have been conventionally proposed, but as those related to the present invention, for example, "vaporization" described in Patent Document 1. There is a "cold pillow that uses heat".

The above-mentioned "cold pillow using heat of vaporization" has a structure in which a sponge absorbed in water is wrapped in a resin film having a large number of small holes and housed in a styrofoam outer box, and the upper surface thereof is covered with a towel or the like. Have. The weight of the head placed on the pillow pushes out the water in the sponge, and the towel on it evenly moistens the towel by capillarity, and when the water in the towel evaporates, the towel and its vicinity It takes heat away and cools the towel.

The "cold pillow using heat of vaporization" described in Patent Document 1 has a complicated structure and many constituent members. Therefore, when using this "cold pillow", a large number of sponges absorbed with water are used. What is wrapped in a resin film having small holes is housed in a foamed styrene outer box, and the upper surface thereof is covered with a plurality of thin resin films having a large number of holes whose inner diameters are gradually reduced, and a towel is placed on the upper surface thereof. It is necessary, and the preparatory work until it can actually be used is troublesome.

In addition, since the "cold pillow" is used in the summer when there is a lot of sweating, it is desirable to wash it after each use from the viewpoint of hygiene. It takes a lot of time and effort for maintenance such as cleaning.

Therefore, the problem to be solved by the present invention is to provide a cooling pillow which has a relatively small number of constituent members, has a simple structure, exhibits an excellent cooling action, and is easy to maintain.

The cooling pillow according to the present invention
An accommodating member made of a flexible impermeable material with an opening on the top surface,
A cooling member having water absorption arranged so as to be able to be taken in and out of the accommodating member,
It is characterized by including a heat shield member that covers the accommodating member in a state where the opening is exposed upward.

In the cooling pillow, a film material made of a natural resin or a synthetic resin can be used as the accommodating member.

In the cooling pillow, the cooling member and the heat shield member are made of a towel, a cloth material, a non-woven fabric material formed of a natural fiber, a synthetic fiber or a mixed fiber thereof, or a porous material formed of a synthetic resin. One or more of them can be used.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a cooling pillow which has a relatively small number of constituent members, has a simple structure, exhibits an excellent cooling action, and is easy to maintain.

It is a partially omitted plan view which shows the cooling pillow which is an embodiment of this invention. It is a partially omitted sectional view in line AA in FIG.

Hereinafter, the cooling pillow 10 according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIGS. 1 and 2, the cooling pillow 10 has an accommodating member 5 which is made of a flexible impermeable material and has an opening 6 on the upper surface, and water absorption which is arranged so as to be taken in and out of the accommodating member 5. It includes cooling members 1, 2, 3 and 4, and a heat shield member 7 that covers the accommodating member 5 with the opening 6 exposed upward.

The accommodating member 5 is made of a rubber film material which is one of natural resins, but is not limited to this. Therefore, any other flexible non-permeable material is made of synthetic resin (for example,). , Silicon rubber, polyethylene, vinyl, etc.) film material can also be used.

The cooling members 1, 2, 3 and 4 and the heat shield member 7 use towels made of cotton, which is a natural fiber, but the present invention is not limited to this. Towels, cloth materials, non-woven materials made of mixed fibers of fibers and synthetic fibers, porous materials made of synthetic resin, and the like can be used.

Next, how to use the cooling pillow 10 will be described. Since the usage of the cooling pillow 10 is not limited, the usage is not limited to the usage described later. As shown in FIG. 2, a plurality of cooling members 1, 2, 3 and 4 having water absorption and water retention are sucked in moisture, and these cooling members 1, 2, 3 and 4 are sequentially accommodated from the opening 6. It is charged into the member 5 and arranged in a laminated state. Since the number and thickness of the cooling members 1, 2, 3 and 4 are not limited, the number can be increased or decreased depending on the user's preference and usage conditions.

Next, the outer peripheral surface 5a and the bottom surface 5b of the accommodating member 5 are covered with the heat shield member 7 in a state where the opening 6 is exposed upward. The heat shield member 7 uses a dry towel, but the heat shield member 7 is not limited to this.

After that, if the head H of the user lying on his back to go to bed is placed on the opening 6 exposed on the upper surface of the cooling pillow 10, it can be used in the same manner as a normal pillow. Since the accommodating member 5 is made of a flexible material, when the head H is placed on the opening 6, the weight of the accommodating member 5 elastically causes the upper surface 5c portion of the accommodating member 5 to follow the shape of the head H. As it bends, a part of the upper surface 1a of the cooling member 1 exposed to the opening 6 protrudes toward the head H and comes into contact with the occipital part. In this way, when the head H comes into contact with the cooling member 1 containing water, the head H is cooled, so that a comfortable sleep can be obtained even in a hot season.

Further, the water contained in the cooling member 1 in contact with the back of the head portion is vaporized (evaporated) by the body temperature, and at this time, the heat of vaporization (heat of vaporization) is taken away, so that the temperature rise of the cooling member 1 can be suppressed. It is effective in promoting comfortable sleep.

On the other hand, when the water vaporizes (evaporates) from the upper surface 1a of the cooling member 1, the water contained in the cooling member 1 decreases, but the water contained in the cooling members 2, 3 and 4 is sequentially supplied into the cooling member 1. Therefore, the water does not run out, and the head H can be kept cooled for a long time (for example, about 8 to 10 hours).

Further, since the outer peripheral surface 5a and the bottom surface 5b of the accommodating member 5 are covered with the heat shield member 7, it is possible to prevent the temperatures of the cooling members 1, 2, 3 and 4 from rising due to the ambient air temperature. Since the heat shield member 7 is a dry towel having water absorption, it is possible to prevent the dew condensation water generated on the outer peripheral surface 5a and the bottom surface 5b of the accommodating member 5 from leaking and wetting the bedding and the like.

Since the cooling pillow 10 is formed of cooling members 1, 2, 3 and 4, accommodating members 5, and heat shield members 7, it has a relatively small number of constituent members and has a simple structure, and has a head H and cooling. The cooling member 1, 2 It is possible to suppress the temperature rise of 3 and 4.

Further, after using the cooling pillow 10, the cooling members 1, 2, 3 and 4 are taken out from the opening 6 of the accommodating member 5 and washed, or the inside of the empty accommodating member 5 is cleaned from the opening 6. Since the heat shield member 7 can be attached to and detached from the accommodating member 5, maintenance is easy.

The cooling pillow 10 described with reference to FIGS. 1 and 2 shows an example of the cooling pillow according to the present invention, and the cooling pillow according to the present invention is not limited to the above-mentioned cooling pillow 10.

The cooling pillow according to the present invention can be used when sleeping in a hot summer or the like, and can be widely used in an industrial field such as a bedding manufacturing industry.
