Definitions

  • the present invention enables, when a consumer uses a product officially released on the market as a heating element, to store the product, suppress the reaction of the heating element that is the product, and increase the effective heat generation time of the product.
  • This invention relates to a reaction-limiting bag that lasts longer than the rated duration, and to clothing on which this reaction-limiting bag is attached.
  • a typical example of a product that serves as a heating element is a disposable body warmer.
  • Disposable body warmers generally utilize the heat generated during oxidation of iron powder, and are ⁇ oxidation-limiting heating elements'' in which the rate of heat generation is determined by the oxidation reaction.
  • a type of oxidation-controlled heating element in which a heat-generating composition such as iron powder is encapsulated in an air-permeable packaging material such as non-woven fabric or paper, which is housed in a packaging bag made of a material that does not allow air to pass through. . When using the product, remove the packaging bag to expose the breathable packaging material.
  • nonwoven fabric In the case of nonwoven fabric, it is breathable because it has pores of several ⁇ m to several tens of ⁇ m, although it depends on the diameter and basis weight (mass per unit area) of the fibers. Although it depends on the size and purpose, most products have a rated duration of about 12 to 20 hours. This rated duration refers to "the amount of time that a temperature of 40°C or higher is maintained", and the characteristics of the breathable packaging material are adjusted so that the maximum temperature is 60 to 70°C and the average temperature is 50 to 60°C. There seem to be many. Therefore, if current disposable body warmers are used normally and the rate is determined by the characteristics of the breathable packaging material, the heating effect will disappear after half a day to a little less than a day of use, and the body warmers will have to be discarded.
  • the temperature of disposable body warmers is generally too high for human skin, so in order to use them comfortably, it is necessary to lower the temperature by placing clothing or other cloth between them and the skin. It takes time to make adjustments. Since the temperature of the warmer drops several hours after the start of use, it becomes necessary to remove temperature-adjusting clothing and the like in order to continue using the warmer comfortably.
  • the average temperature of disposable body warmers is 50 to 60°C, which is a temperature range that is sufficiently high to cause low-temperature burns even if the body warmer comes into indirect contact with the human body through clothing or the like. No matter how comfortable the user feels, keeping a disposable body warmer in close contact with the same area increases the possibility of low-temperature burns.
  • Patent Document 1 describes the idea of a disposable body warmer cover partially coated with an aluminum processed film for the purpose of using the rated duration of the disposable body warmer more effectively and comfortably for a longer period of time.
  • An aluminum processed film is applied to the side that does not come into contact with the human body, which prevents heat from dissipating from that side, and also reduces air inflow from that side, lowering the chemical reaction rate of the warmer and making it last longer. It is said that there is.
  • the material of the other surface facing this surface is cloth, the amount of air inflow cannot be controlled, and it is not expected to be very effective in reducing the chemical reaction rate of the body warmer.
