2. Description of the Related Art Chronic painful diseases in the field of orthopedics, such as chronic low back pain, stiff shoulders, muscular pain, stiff muscles, cold limbs, neuralgia, rheumatism and the like are mainly caused by poor blood circulation. For these diseases, warming is often more effective than cooling, and for a long time, local treatment of this human body has been
It is widely and generally used as a therapeutic means (thermotherapy) for imparting a thermal effect such as blood circulation promotion.

[0003] Conventional heat therapy includes towels and konjac heated with hot water, hot packs and hot water bottles filled with hot water, hot gel pats or warmers and disposable warmers,
Alternatively, a method of directly applying a fire or an electric fire to an affected part has been adopted.

[0004] However, in thermal therapy using a heated towel or konjac, or a hot pack or hot water bottle, it is difficult to control the heat generation temperature, that is, the temperature becomes too high to cause a burn, or the temperature becomes too low to provide sufficient heat.・ There is a problem that the compressing effect cannot be obtained.In addition, since the heat dissipation is extremely high, the sustainability of the predetermined temperature at which the heating and compressing effect can be obtained is extremely poor, and only a short-time heating and compressing effect can be obtained. In a short period of time, the heat of vaporization is removed from the heating device and cooled, resulting in problems such as the affected part being cooled and adverse effects such as exacerbation of symptoms, and safety, usability and simplicity. It was missing.

[0005] In particular, heated towels, konjac, hot packs, hot water bottles and the like are difficult to heat with hot water or a heater, and when starting to use, use several buffer materials such as towels. There is a problem that the temperature is so high that it must be heated and the temperature drops in a short time.

By the way, in order to sufficiently obtain the therapeutic effect of hyperthermia, it is necessary to continuously provide a certain degree of warmth to the affected part.

[0007] For example, when a warm compress is used in close contact with the human body, it is usually at a constant temperature of 2 to 3 ° C or higher than the skin temperature, that is, at a temperature of about 38 ° C or higher, for 4 to 5 hours or more. It is required that the hot compress can be applied for a long time.

[0008] In particular, in thermotherapy in winter or cold regions, it is required that a hot compress can be applied at such a temperature for a long time in order to obtain a sufficient therapeutic effect.

However, since none of the above-mentioned various heating tools generates heat themselves, the heating tool is deprived of vaporization heat in a short time (about 1 to 2 hours) and cooled. It is difficult to continuously provide this level of heat.

[0010] In this respect, a warmer, a disposable warmer, a fire or an electric fire have a simple effectiveness in providing such a degree of continuous heat, for example, at a temperature of about 45 ° C for a long time. It can apply heat to the application site over a long period of time, and is excellent in simplicity and handleability.

[0011]

However, at present,
Generally, a commercially available heating tool such as a warmer, a disposable warmer, a glow or an electric glow has a simple effect in terms of the continuous application of heat, and furthermore, it can cure an affected part at a temperature of about 45 ° C. for a long time. It is intended to warm, but if it is used for a long time in close contact with the human body at such a temperature, it may cause low-temperature burns.

To solve this problem, it is conceivable to use a cushioning material such as a cloth or a towel to prevent the heating tool from coming into direct contact with the skin surface. Poor buffering capacity, ie 1 or 2
Even if it is used in a stack, it is not possible to obtain a sufficient effect for preventing low-temperature burns.

[0013] However, when three or more cloths or towels are used in a stack, not only is the stiffness deteriorated, but also the transfer of warm heat to the object is inferior. Insufficient heat radiation occurs in the middle heating tool, and the heat generation temperature in the buffer material becomes extremely high, such as 50 ° C. or higher, and conversely, the shortage of oxygen supply occurs in the heating tool in the cloth or towel, and the heating tool generates the heat. Since a decrease in heat occurs, there is a problem that lack of simplicity and safety is required in effective use of heat and control of temperature.

By the way, recently, a thermal gel pad obtained by enclosing a hydrogel containing water and a water-absorbing polymer as essential constituent materials in a bag material has been researched and developed, and has appeared on the market.

That is, this hot gel pad is used by heating it in a microwave oven for home use for about 2 to 3 minutes, and is economical because it can be used repeatedly.
Further, the temperature can be easily controlled simply by adjusting the heating time in the microwave oven, and there is an advantage that the simplicity, the handling property and the safety are excellent.

However, in order to prevent low-temperature burns in the hot gel pad, the heating time of the microwave oven is shortened and the heat radiation temperature of the heating tool is adjusted to a relatively low temperature that does not cause low-temperature burns. Cannot obtain sufficient hyperthermic effect.

Therefore, when such a thermal gel pad is actually used, the initial heat radiation temperature of the heating tool is set to 45 ° C.
Adjusting back and forth, and using a cushioning material such as a cloth or towel between the skin surface and the heating tool to prevent low-temperature burns, but in such usage conditions, heat is easily dissipated However, there is a problem in terms of effective use of heat, and it is difficult to obtain the effect of heat treatment.

Further, since the thermal gel pad uses a hydrogel having relatively low thermal conductivity, a certain amount of heat can be applied for a longer time than a hot pack or a hot water bottle. Since the gel itself does not generate heat, in a use state in which such heat is easily dissipated, the temperature decreases immediately after the start of use, and the heat that is actually applied to the application site (for example, 38 ° C.) The time during which the above-mentioned heat can be applied is at most about 2 hours.

However, despite these serious problems, studies on the effective use of these heating tools and the like up to now have been limited to the case where they are simply enclosed in a simple cover for improving the usability. Therefore, it is possible to improve the safety, such as prevention of low-temperature burns during the use of the heating tool by installing the heating tool, without deteriorating the feeling of use, and to transmit the temperature of the heating tool and effectively use the heat. Very little research and development has been done on the superior heat-insulating storage devices.

The inventor of the present invention has conducted intensive studies in order to solve the above-mentioned technical problems. As a result, in the heat-retaining storage device which is used by attaching to such a heating device for applying heat to the application site, When this heat-retaining storage device is constituted by a sheet material having a cloth base material and a heat-retaining material as essential components, the occurrence of skin disorders such as low-temperature burns is prevented, and the effective heating of the heating device is maintained and maintained for a long period of time. It was found that it could be a storage container for heat retention.

That is, the inventor of the present invention has proposed a heat-retaining storage device for mounting a heat-retaining device, wherein the heat-retaining storage device is made of a sheet material having a cloth base material and a heat-retaining material as essential components. It has been found that even when the heat storage device is used by attaching it to a heating device, the feeling of use is not impaired because the storage device can be formed thin.

Further, by forming the heat-retaining storage device in such a small thickness, poor heat radiation occurs in the heating device in the heat-retaining storage device, and the heat generation temperature in the buffer material becomes extremely high.
Conversely, the inventor has also found that it is possible to prevent a shortage of supply of oxygen from occurring in the heating tool in the cloth or towel, thereby preventing a decrease in the heat generated by the heating tool.

Further, the present inventor relates to a heat storage container,
It has also been found that by forming such a thin film, it is possible to transmit heat appropriately to the application site promptly and improve the effective use of heat.

In particular, the present inventor, when using a material having a far-infrared function as a heat-insulating material in a heat-insulating storage device, imparts sufficient heat to the deep portion at the application site by the far-infrared effect. They also learned that they could do it.

The present invention has been completed on the basis of the above-mentioned findings, and the heat-retaining storage device is made of a sheet material having a cloth base material and a heat-retaining material as essential components. As a result, the heat can be transmitted quickly and appropriately to the application site without deteriorating the feeling of use, the effective use of the heat can be improved, and skin disorders such as low-temperature burns can occur. It is an object of the present invention to provide a heat-retaining storage device that can prevent the occurrence of heat, and can maintain and maintain the effective heat of the heating device over a long period of time by a heat-retaining effect of a heat-retaining material and / or a far infrared ray effect.

[Table 1]

In Examples 1 to 3, the surface temperature was measured at a substantially central portion on the heating surface of the heat retaining container in the state where the device was mounted on the heat retaining container of the present invention. -About 2, the approximate center of the surface of the towel wrapped with the heating tool was measured, and in Comparative Example 3, the approximate center of one side of the heating tool was measured.

From the results shown in Table 1, it was found that in Examples 1 to 3, the surface temperature was less than 40 hours within 1 hour after the start of the test.
It was confirmed that the temperature rapidly rose to not less than ° C and that the heat of 38 ° C or more was maintained and maintained even after 6 hours had passed.

On the other hand, in the case of Comparative Examples 1 and 3, the surface temperature rises immediately after the start of the test, but the heat of 38 ° C. or more is maintained only for about 1 to 2 hours after the start of the test. Was not obtained, and it was recognized that it was inferior in application of heat over a long period of time.

Further, in the case of Comparative Example 2, it was confirmed that the heat of 38 ° C. or more was maintained after 6 hours, but the rise in surface temperature after the start of the test was slow. Since heat does not exceed 38 ° C. or more until 3 hours after the start of the test, it is inferior in terms of rapid application of heat, and considerable heat radiation is observed, which is insufficient from the viewpoint of effective use of heat. Admitted.

In the present invention, the heat storage container 1 is used.
Is not limited to a cloth-like or bag-like form, and the sheet material 4 may be formed into a use form according to the type of the heating tool 6 and the heating (heating) target to which the heating is applied. It is.
