Temperature control agent, and heating composition, packaging material, and warming material each including same

Abstract

The purpose of the present invention is to provide: a means for simply rendering control of the temperature of a warming material possible at lower cost, the means being usable instead of or in combination with the conventional temperature control performed by controlling the supply amount of oxygen or air with an air-permeable film or the like; and a warming material including the temperature control means. The invention further provides: an advanced temperature control means which is utilizable for warming materials for medical use; and an improved warming material for medical applications which is safer and more effective. The temperature control agent according to an embodiment of the invention is for controlling the heating temperature of a warming material including a heating composition which generates heat upon reaction with oxygen, and is characterized by comprising one or more aliphatic compounds which have a melting point of 35-65oC and have a solubility in water (g / 100 mL) at 20oC of 5 or less.

Description

technical field [0001] The present invention relates to a temperature control agent for warming materials such as a chemical portable heater (kairo) that generates heat by reacting with oxygen, and a wet compress structure, an exothermic composition and a packaging material using the temperature control agent, and Use their warm material. Background technique [0002] A warming material using a heat-generating composition that generates heat in contact with oxygen or air is generally used as a warm-moist compress for relieving pain by warming, a medical device such as a warming appliance for meridian stimulation, or as a portable medical device for cold protection. Daily necessities such as heating appliances and other heating appliances are widely used. [0003] The exothermic composition used in such heating materials most usually contains metal powders such as iron powder, salts such as table salt, water, and water-retaining agents such as activated carbon, etc. as const...

Problems solved by technology

However, in actual use, depending on the type of shoes, the amount of air to be supplied may vary, resulting in uneven temperature or a sudden rise in temperature when taking off the shoes.

[0006] Also, the same problem exists in warming materials for medical applications that require more precise temperature control

For example, the percutaneous absorption type medical warm-moist compress combined with a heating element and a drug is advertised to have the advantages of increasing the effect and reducing the dosage of the drug due to the efficiency of the transdermal absorption caused by heat, but as mentioned above, there are The above-mentioned problem: the stability of the exothermic temperature in the conventional temperature adjustment is not sufficient, so the actual temperature is unstable, and thus the dosage of the drug is unstable

Furthermore, as a substitute for moxibustion that does not use fire, there is also a demand for short-term use of heating elements, but moxibustion is in a high-temperature area, so disposable portable heating appliances that lack temperature stability are technically risky and have not been popularized.
