[Industrial Application Field] The present invention relates to a packaging material for storing heat insulators such as body warmers, anchors, hot water pads, and other so-called disposable body warmers, or heat-generating materials for disposable body warmers, and for emitting far-infrared radiant energy. be. [Prior Art] Conventionally, general-purpose fibers have been used as the packaging material for heat insulators such as body warmers, anchors, and hot water pads, and specially processed paper has been used as the packaging material for heat generating materials for so-called disposable body warmers. [Problems to be solved by the invention] However, the above-mentioned conventional packaging materials for heat insulators,
Because it does not have far-infrared radiation characteristics, far-infrared radiant energy is not emitted, and therefore, far-infrared irradiation can promote blood circulation due to hyperemia, metabolism, and other medical effects and health promotion effects. The problem was that we could not expect anything at all. The present invention aims to solve the above problems. [Means for Solving the Problems] In order to solve the above problems, the present invention provides a reflective layer by coating a mixture of adhesive and aluminum particles on the surface of a base fabric made of fibers, and The surface of the reflective layer is coated with a mixture of adhesive and ceramic particles that have far-infrared radiation characteristics with an average far-infrared emissivity of 65% or more in the wavelength range of 4.5 to 30 μm at 30°C to emit far-infrared rays. The above-mentioned problem was solved by forming a bag body for storing a heat insulating body using a far-infrared ray emitting sheet formed by providing layers. [Function] According to the packaging material of the present invention having the above configuration, far-infrared radiation energy is emitted from the far-infrared radiation layer even at room temperature, but the temperature of the heat insulator increases and the far-infrared radiation sheet is heated. As a result, far-infrared radiation energy with even higher emissivity is radiated from the far-infrared radiation layer. The radiant energy radiated from the far-infrared radiation layer toward the reflective layer is reflected 180 degrees toward the human body by the reflective layer, and the total radiant energy is radiated only in one direction toward the human body. [Example] An example of the present invention will be explained in detail with reference to the drawings.
A reflective layer 6 is provided by mixing and applying an adhesive and aluminum particles, and on the surface of the reflective layer 6,
Adhesive and far infrared emissivity at 30℃ is wavelength 4.5
A bag body 3 is formed by a far-infrared emitting sheet 2 formed by providing a far-infrared emitting layer 1 by mixing and coating ceramic particles having far-infrared radiation characteristics of 65% or more on average in the region of ~30 μm. The bag body 3 is formed in such a manner that a heat insulating body 4 such as a body warmer, an anchor, a hot water bottle, other so-called disposable body warmers, or a heat generating material for a disposable body warmer can be stored therein. That is, since it is an essential component of the present invention that the bag body 3 is formed of the far-infrared ray emitting sheet 2, the far-infrared ray emitting sheet 2 will be described first. There are various substances that have far-infrared radiation characteristics, but
The material with far-infrared radiation characteristics that can be used in this invention has a far-infrared emissivity at 30℃ with a wavelength of 4.5~
It is necessary to have an average of 65% or more in a region of 30 μm, preferably 75% or more, particularly preferably 90%
That's all. Examples of the substance having far-infrared radiation characteristics include oxide ceramics, non-oxide ceramics, nonmetals, metals, alloys, and crystals. For example, oxide ceramics include alumina (AI 2 O 3 ), magnesia (MgO), and zirconia (ZrO 2 ), as well as titanium oxide (TiO 2 ), silicon dioxide (SiO 2 ), and chromium oxide (Cr 2 O 3 ), ferrite (FeO 2 , Fe 3 O 4 ), spinel (MgO・AI 2 O 3 ),
There are cerium (CaO 2 ), barium (BaO), etc.
Carbide ceramics include boron carbide (B 4 C), silicon carbide (SiC), titanium carbide (TiC), molybdenum carbide (MoC), tungsten carbide (WC), etc., and nitride ceramics include nitride Examples include boron (BN), aluminum nitride (AIN), silicon nitride (Si 3 N 4 ), zircon nitride (ZrN), etc. Nonmetals include carbon (C) and graphite, and metals include tungsten (W). , molybdenum (Mo), vanadium (V), platinum (Pt), tantalum (Ta), manganese (Mn), nickel (Ni), copper oxide (Cu 2 O), iron oxide (Fe 2
O 3 ), and its alloys include nichrome, kanthal,
Stainless steel and alumel are available, and crystals include mica, fluorite, calcite, alum, and quartz. Figure 2 is a far-infrared emissivity distribution map. Curve A
is the radiation spectrum of alumina, curve B is the radiation spectrum of magnesia, and curve C is the radiation spectrum of zirconia, and the wavelength is 4.5.
In the region of ~30 μm, the average emissivity is 75% or more and can be used in the present invention. Curve D is the radiation spectrum of zircon carbide (ZrC), which is a non-oxide carbide ceramic, and curve E is the radiation spectrum of titanium nitride (TiN), which is also a non-oxide nitride ceramic. Its average emissivity is less than 60%, so it cannot be used alone in the present invention. Curve F is the emission spectrum of transparent quartz ceramics. Its average emissivity is 40
% or less and cannot be used alone in the present invention. Far-infrared emissivity can be determined by measuring the spectrum as described above, but emissivity depends on the substance, its purity, particle size or crystal system,
It is determined by square, hexagonal, monodirectional, cubic, three-sided, oblique, etc. Particularly useful ceramics having far-infrared radiation properties include alumina-based, magnesia-based, and zirconia-based ceramics. If this is further classified, alumina-based materials include alumina and mullite, magnesia-based materials include magnesia and cordierite, and zirconia-based materials include zirconside (ZrO 2 ·SiO 2 ) and zircon (ZiO 2 ). It is also effective to use a mixture of one or more selected from the above group, and one or more selected from the above group and other ceramics (for example, carbide ceramics). ) is also effective. Figure 3 shows an example of emissivity when composite ceramics are used in combination. Curve G in Figure 3 shows the emissivity of a composite ceramic made of a 1/1 mixture of zirconia (ZrO 2 ) and chromium oxide (Cr 2 O 3 ), and curve H in Figure 2 shows the emissivity of alumina (AI 2 O 3 ) . ) and magnesia (MgO) in a 1:1 ratio, both of which are useful for this invention. The higher the purity of particles having far-infrared radiation characteristics as described above, the better, and a high emissivity is often obtained when the purity is 95% or more. For example, Figure 4 shows the emissivity when the purity of alumina is 95% (curve I) and 85% (curve J), respectively, and Figure 5 shows the emissivity when the purity of mullite is 95% (curve K) and 85%, respectively. % (curve L), and both show that the higher the purity, the higher the emissivity. The far-infrared emitting sheet 2 used in the present invention uses the fiber structure obtained in Utility Model Application No. 1983-38534 (Utility Model Application No. 1983-145894) proposed by the present inventor. It is recommended that you do so. The fiber structure proposed in the above-mentioned Utility Model Application No. 62-38534 has a reflective layer made of aluminum particles adhered to a base fabric, and has a far-infrared emissivity at 30°C that corresponds to the wavelength.
The gist is that a far-infrared radiation layer is formed by bonding ceramic particles that have far-infrared radiation characteristics of 65% or more on average in the 4.5 to 30 μm region, and the present invention uses this fiber structure. This is the far-infrared radiation sheet 2 to be used. This far-infrared emitting sheet 2 has a base fabric 5 made of a general-purpose fiber such as nylon, and the surface of the base fabric 5 is coated with an adhesive made of, for example, polyurethane and aluminum particles with excellent reflectance, without any particular limitation. Aluminum particles having a particle size of 10 μm or less are mixed and coated to form a reflective layer 6 having a thickness of preferably 10 to 20 μm, although not particularly limited, and on the surface of the reflective layer 6. , an adhesive made of polyurethane and ceramic particles made of alumina-based, zirconia-based, magnesia-based, or a composite thereof having far-infrared radiation properties as described above, although not particularly limited, are preferred.
The far-infrared emitting layer 1 is formed by mixing and coating ceramic particles having a particle size of 10 μm or less, and preferably having a thickness of 10 to 20 μm, although there is no particular limitation. It is recommended that both the reflective layer 6 coated with aluminum particles and the far-infrared radiation layer 1 coated with ceramic particles have microporous micropores of around 1 μm in size, and these micropores provide breathability. be done. In the examples, aluminum is used as the reflective layer 6 because aluminum is a material with high reflective properties and heat retention properties. To explain the operation of the embodiment, a body warmer, an anchor, a hot water bottle,
When a heat insulating body 4 such as a disposable body warmer or a heat generating material for a disposable body warmer is stored and brought into contact with the human skin surface, as the temperature of the heat insulating body 4 rises, the temperature of the far infrared radiation sheet 2 also rises, and far infrared rays are emitted even at room temperature. Far-infrared radiant energy is emitted from the radiation layer 1, but by heating the far-infrared radiation sheet 2, far-infrared radiant energy with a higher emissivity and more effective for health than the far-infrared radiation layer 1 is emitted. radiated. At this time, the radiant energy radiated from the far-infrared radiation layer 1 is divided into two types: radiant energy radiated toward the human body, and radiant energy radiated from the far-infrared radiation layer 1.
The radiant energy radiated toward the side of the reflective layer 6 is reflected 180 degrees toward the human body by the reflective layer 6, and the total radiant energy is radiated only in one direction toward the human body. be done. What is shown in the table is a comparison table in which the temperature conditions of a packaging material using the far-infrared emitting sheet 2 according to the present invention and a general-purpose packaging material were tested.

The packaging materials of the present invention according to the above table have lower center and surface temperatures than general-purpose packaging materials, but in the case of the packaging materials of the present invention, the sensible temperature is the same as that of general-purpose packaging materials due to its far-infrared effect. As a result, when using the packaging material of the present invention, it has the same level of thermal effect as a conventional heat insulator at a lower temperature. [Effects of the invention] Since the present invention is as described above, far-infrared radiant energy is emitted from the far-infrared radiation layer even at room temperature, but the temperature of the heat insulator increases and the far-infrared radiation sheet is heated. As a result, far-infrared radiant energy with higher emissivity is radiated from the far-infrared radiation layer, and the radiant energy radiated from the far-infrared radiation layer toward the reflective layer is reflected 180 degrees toward the human body by the reflective layer. Since the total radiant energy is radiated only in one direction towards the human body, the far-infrared radiation effect causes thermal molecular movement in the human body, promoting blood circulation, and promoting metabolism, in addition to the heat retention from the heat insulating body. Not only can medical effects and health promotion effects be obtained, but even with a warmer that operates at a lower temperature than conventional warmers, it has the same level of thermal effect as conventional warmers due to the far-infrared radiation effect.
