[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention cools the eyes and the surroundings of the eyes at a temperature that does not cause noxious stimuli or reduces noxious stimuli against eye strain caused by hot flashes and dry eyes. The present invention relates to an eye pillow that relaxes and improves eye strain by heating with steam at a temperature that does not reach a level, provides comfort such as relaxation and refreshment, and induces a good night's sleep.

[0002]

2. Description of the Related Art In today's stressful society where information is flooded, many people complain of eye fatigue (eye strain). As one of the main causes of eye strain, VDT (Visual Display Terminal) work such as computer work, driving a car, watching TV or video, watching a video game, learning, reading eyes, etc. are considered. These VDT
During work, etc., the eyes are put in a gaze state where the number of blinks is extremely small, resulting in redness of the eyes, hypertension of the regulatory muscles around the eyes,
This is because the evaporation amount of tears, which is an important protective component of the eye surface, is increased, and the eyes are dried. In addition, since the environment in which VDT work is performed today is generally in an air-conditioned, low-humidity state and the eyes are easily dried, it is considered that this also promotes eye strain due to dry eyes. ing.

Further, recently, contact lenses used by many people are used by being worn on the cornea in a state of floating in tears. Therefore, especially for a person with a small amount of secreted tears, when the eyes are dry, the cornea may be damaged by the contact lens, and the drying of the eyes causes a problem that is not limited to mere eye strain.

Further, since long-time OA work accumulates not only eye fatigue but also mental stress, an increasing number of modern people are complaining of troubles such as unstable mental condition and insomnia with eye strain. There is.

For such eye strain, eye drops such as eye drops, and a cold towel or a steam towel are applied as a coping therapy. In addition, eye pillows are used to apply appropriate weight to the eyes and the area around the eyes to relax the mood and induce sleep.

It cannot be easily prepared and may not always be available at any place.

In addition, as a method for cooling the eyes, a cooling / heating material pack using a water-containing agent and an endothermic agent that reacts with water to cause an endothermic reaction is known. However, the cooling and heating material pack is focused on how to lower the temperature of the pack itself or how to lengthen the keeping time of the pack, and it is effective to apply it to the eyes for a short time. It has not been able to eliminate eye strain and stress.

As a method of supplying hot steam to the eyes,
A method of heating water by using chemical energy such as heat of neutralization of acid and alkali, heat of hydration of inorganic salt, heat of oxidation of metal such as iron powder and supplying hot steam can be considered. But,
Even if only the hot steam supplied by these methods is used, it is difficult to control the steam temperature, and direct supply has a problem in safety.

Further, the eye pillow is used as a method for eliminating stress and insomnia by appropriately weighting the eyes and the area around the eyes. However, the effect that can be confirmed objectively has not been obtained.

With respect to such conventional coping therapy methods,
The present invention prevents dryness or hot flashes that cause eye strain or other problems, stress due to overuse of the eyes, or to prevent or heal insomnia. In addition, it is an object of the present invention to provide an eye pillow that guides the eye and the area around the eye continuously and presses the eye and the area around the eye with an appropriate force.

In order to achieve the above object, the present invention provides an eye pillow body which is applied to the eyes and the vicinity of the eyes.
And eye pillow body is detachably attached to provide a cooling body utilizing chemical energy and cooling and warming eyes pillow made of heat steam generator that utilizes chemical energy.

According to the cooling / heated eye pillow of the present invention, either a cooling body or a heat / steam generator can be used depending on the symptoms of eye fatigue, taste, effect, use scene, etc. of the person applying the eye pillow. Either one or both of them can be attached to the eyes and the eyes and the surroundings of the eyes while being appropriately pressed to cool or supply hot steam, and these can be alternately performed.
Therefore, according to the cooling / heated eye pillow of the present invention, it is possible to obtain a feeling of effect without being restricted by symptoms, preferences, and situations.

According to the cooling / heated eye pillow of the present invention,
Since chemical energy is used for the cooling body and the thermal steam generator, the eyes and eyes can be easily and easily compared with the case where the eyes and the area around the eyes are cooled with a towel or the steam is supplied with hot steam. The surroundings can be cooled or hot steam can be supplied.

[0015]

It is preferable because the cooling body and the hot steam generator can be easily attached to and detached from the body pillow body.

On the other hand, in the present invention, the cooling body uses chemical energy.

As the cooling characteristics of the cooling body, the cooling body is applied to the eyes and the area around the eyes, and the skin temperature around the eyes is 15 ° C. or more one minute after the cooling is started and before the cooling is started. It is preferable to cool the temperature to 5 ° C. or more lower than that and maintain the skin temperature around the eyes in such a temperature range for 300 seconds or more. By keeping the skin around the eyes at 15 ° C. or higher even after the application of the cooling body, it is possible to cool the eyes and the vicinity of the eyes comfortably and safely without irritating the skin excessively. Further, one minute after the start of cooling, the temperature can be cooled to 5 ° C. or more lower than before the start of cooling, and by maintaining such a temperature for 300 seconds or more, a sufficient effect of cooling can be obtained.

The chemical energy used by the cooling body may be an endothermic reaction due to mixing with water. Examples of the cooling agent component that causes such an endothermic reaction include inorganic ammonium salts such as ammonium nitrate, ammonium sulfate, ammonium phosphate, diammonium hydrogen phosphate, ammonium metavanadate, ammonium chloride, ammonium bromide, and ammonium iodide, and urea. I can give you.

These cooling agent components and water are isolated and separately sealed in a bag until the cooling body is stored or before the cooling body is attached to the main body of the eye pillow and used. Is preferably mixed.

If desired, various additives may be added to the reaction system of the cooling agent component and water. For example, when it is desired to obtain a certain degree of viscosity when the cooling agent component and water are mixed, a gum agent such as xanthan gum or guar gum, a water-absorbing polymer or the like is used as a thickening agent per 1 part by weight of the cooling agent component. ~ 5 parts by weight can be added. Further, in order to realize the above-mentioned cooling characteristics in this system, it is preferable that the compounding composition is 67 to 200 parts by weight of water and 1 to 5 parts by weight of gum for 100 parts by weight of the cooling agent component.

There are no particular restrictions on the constituent material of the bag in which the cooling agent component, water, etc. are enclosed. For example, a synthetic resin film such as polyethylene, polypropylene or polyamide may be used as a single layer or a multilayer film, or a metal foil may be laminated on these films. Alternatively, a metal-deposited film or the like may be used.

The structure of the bag for enclosing the cooling agent component, water, etc. is such that (i) the outer bag is enclosed so that these can be isolated and enclosed during storage or before use of the cooling body and can be mixed when necessary. It may have a double structure in which an inner bag is further provided, or (ii) a structure in which a partition is provided inside the bag and the inside of the bag is divided into two or more chambers.

Among these, as a specific example of the double structure of (i), for example, the inner bag is filled with water and the cooling agent component is sealed between the inner bag and the outer bag, or the inner bag is Then, a cooling agent component is filled in and water is sealed between the inner bag and the outer bag. In this case, the inner bag is formed so as not to be easily broken in a normal storage state, but to be broken when an external force is applied when the cooling body is used. For this purpose, the film material forming the inner bag is made relatively weaker than the film material forming the outer bag, or
Alternatively, the strength of the seal portion of the inner bag is made relatively weaker than the strength of the seal portion of the outer bag.

As a specific example of the structure (ii), for example, the cooling agent component is enclosed in one of the two adjacent chambers separated by the partition wall, and water is enclosed in the other. In this case, the partition wall has a forming strength such that two separated chambers communicate with each other by applying an external force when the cooling body is used.

The whole shape of the cooling body is preferably flexible and flat in the natural state. Further, it may have an eye mask-like shape that fits the eyes and the periphery of the eyes. A coating material may be provided on the outer surface of the cooling body.

[0033] As the coating material, it is preferable to use woven natural fibers or synthetic fibers, a nonwoven fabric or the like, the basis weight ^{10g / m 2 ~500g / m 2} , especially 20g / m ² ~30g / m ² And the thickness of the fiber layer is 0.0 when a load of 4 g / m ² is applied.

As a result, a sticky feeling due to dew condensation can be prevented, a soft feel can be imparted, and makeup makeup can be prevented from being applied to a face to which makeup is applied. Furthermore, in order to detachably attach the cooling body to the eye pillow body, when a male member of Velcro (registered trademark) is provided on the eye pillow body,
By covering the cooling body with the covering material made of the woven or non-woven fabric as described above, the detachability of the cooling body from the eye pillow body can be improved.

On the other hand, in the present invention, the hot steam generator also uses chemical energy. in this case,
Examples of the chemical energy include heat of neutralization of acid and alkali, heat of hydration of inorganic salts (calcium chloride, magnesium chloride, calcium oxide, magnesium oxide, zeolite, etc.), heat of oxidation of metal powder, etc. (WO99 / 51174).

The specific utilization mode of such chemical energy is appropriately determined according to the reaction mode of the chemical energy used. For example, when utilizing the heat of neutralization of acids and alkalis, the heat of hydration of inorganic salts, etc., the steam generation unit generates steam by the heating unit that generates heat of neutralization and heat of hydration, and the heat generated from these. And an evaporating part for discharging. In this case, the heating section may separate the reactants to be reacted with each other by the partition wall, and at any time when the steam is generated, the partition wall may be broken to allow the reaction to proceed. The evaporating section may be made of, for example, a fiber aggregate such as paper, woven cloth, or non-woven cloth or a porous body impregnated with water, so that steam is released by the heat generated by the heating section.

When the heat of oxidation of the metal powder is used as the chemical energy, the water vapor generating section is provided with the metal powder (eg, iron, aluminum, zinc, copper, etc.) and salts serving as catalysts (eg,
Alkali metal chlorides such as sodium chloride and potassium chloride, alkaline earth metal chlorides such as calcium chloride and magnesium chloride), and a steam generating composition containing water. This composition contains, if necessary, a water retention agent (for example, vermiculite, calcium silicate, silica gel, silica-based porous material, alumina, pulp, wood powder, water-absorbing polymer, etc.), reaction accelerator (for example, , Activated carbon, carbon black, graphite, etc.) and the like.

The exothermic reaction of this composition is utilized in a heating element generally called a chemical warmer. However, in the conventional chemical warmer, such a composition is used by containing the composition in a bag made of a material having low air permeability and moisture permeability so that water necessary for the reaction does not escape from the heating element. In contrast, the present invention is different in that such a composition is positively used as a steam generating source, and therefore, when the present invention uses this composition, the composition is a moisture permeable sheet material. When the heat is generated, a part of the water existing in the reaction system is turned into water vapor so that it is positively released to the outside of the system.

The temperature of the steam released during the exothermic reaction of the steam generating composition is 60 ° C. or higher when the composition is opened to the atmosphere or close to it without controlling the air flow rate to the composition. If steam above 60 ° C. is continuously applied to the eyes and the area around the eyes, it may cause a safety problem. Therefore, in the present invention, the temperature of the steam released from the surface of the hot steam generator is controlled to 50 ° C or lower.

In the present invention, such temperature control is also performed when utilizing the chemical energy such as the heat of neutralization of the acid and alkali and the heat of hydration of the inorganic salt.

In the present invention, in controlling the temperature of the steam released from the hot steam generator to 50 ° C. or lower,
The temperature is measured by taking out the hot steam generator from the outside air shutoff container in a room temperature environment (25 ° C., 65% RH), and placing the hot steam generator on a styrofoam table with the steam generation surface facing upward. A temperature detector of a thermometer (Tabayes Beck Co., Ltd., Thermo recorder RT-10) is set on the surface of the hot steam generator without applying a load, and the temperature of the hot steam generator surface is set to 15 It is performed by measuring for a minute.

The specific mode of temperature control can be appropriately determined according to the reaction mode of chemical energy used in the hot steam generator, convenience, and the like. For example, the reaction rate is adjusted by appropriately changing the amount of the reactant to be reacted with the hot steam generator, and when the reactant is a particle, the reaction rate is adjusted by appropriately changing the particle size, etc., and thereby released from the surface of the hot steam generator. Control water vapor temperature. In addition, a temperature adjusting material is provided between the accommodation part of the steam generating composition inside the hot steam generating element and the surface of the hot steam generating element, and the water vapor released by the reaction of the steam generating composition passes through the temperature adjusting material. The water vapor temperature may be lowered by. When the temperature is controlled using such a temperature adjusting material, the steam temperature released from the surface of the hot steam generator can be reliably and easily controlled to 50% regardless of the form of chemical energy used by the hot steam generator.
It is preferable because the temperature can be controlled to be not higher than 0.

As the constituent material of the temperature control material, in addition to (1) woven cloth, non-woven cloth, (2) paper, synthetic paper and the like, (3) plastic, natural rubber, regenerated rubber or synthetic rubber is used. At least one of a porous film or a porous sheet, (4) foamed plastic such as urethane foam having perforations, and (5) metal foil such as aluminum foil having perforations can be used.

When temperature control is performed using the temperature control material composed of these constituent materials, the temperature control material also serves as a passage resistance of water vapor. It is appropriately determined according to the material of the temperature control material, the combination mode of a plurality of constituent materials when the temperature control material is laminated so as to reach the eyes and the vicinity of the eyes, and the like. For example, when the temperature control material is formed of a single-layer nonwoven fabric, the thickness thereof is preferably 0.1 mm or more, more preferably 1 mm or more.

In the case of forming the temperature control material from the above-mentioned constituent materials, the temperature control material is composed of plural kinds of constituent materials in order to make the thickness compact and to enhance the temperature controllability of the steam passing through it. It is preferable that the laminate is

Regarding the amount of hot steam generated by the hot steam generator, the amount of hot steam generated per unit surface area on the surface applied to the eyes and around the eyes is 0 from the viewpoint of the effect of supplying steam to the eyes and around the eyes. it is preferably adjusted so that .01mg / cm ² · min or more, and more preferably set to 0.5mg / cm ² · min or more.

Regarding the amount of heated steam generated, the heated steam generator was taken out from the outside air shutoff container under a room temperature environment (25 ° C., 65% RH), and immediately placed on a precision balance which can measure up to 3 decimal places. Then, when the weight is measured for 15 minutes, the weight at the start of the measurement is set to Wt ₀ (g), and 15
When the weight after minutes is Wt ₁₅ (g) and the surface area of the surface of the hot steam generator that is applied to the eyes and the area around the eyes is S (cm ² ), it is calculated by the following formula.

[0047]

[Equation 1] Thermal steam generation rate (mg / cm ² · min) = (Wt ₀ -Wt
₁₅ ) ・ 1000 / 15S

As a specific method for adjusting the amount of water vapor released from the surface of the warm water vapor generator that is applied to the eyes and the area around the eyes to 0.01 mg / cm ² · min or more, for example, a steam generator is used as a chemical warmer. When a composition similar to the above is used, a packaging material or a temperature adjusting material of the composition may be used that has sufficient moisture permeability. More specifically, it is preferable to use a material having a moisture permeability of 600 g / m ² · 24 h or more by the ASTM method (E-96-80D method), more preferably 1000 g / m ² · 24 h or more, and further preferably Is 1500 to
A material having a moisture permeability of 3200 g / m ² · 24 h is used.
