Description

Reaction restriction bags and clothing

The present invention relates to a reaction restriction bag. When a consumer uses a product that has officially entered the market as a heating element, the reaction restriction bag stores the product and suppresses the reaction of the heating element as the product, so that the effective heating time of the product is longer than that of the product. Rated to last longer and on garments equipped with this reaction limiting bag.

A typical example of a product that is a heating element is a disposable heating pack. Disposable heating packs usually utilize the heat generated during the oxidation of iron powder, so they are "oxidation rate-controlled heating elements" that control the heating rate through oxidation reactions. A common product on the market contains an oxidation rate-controlling heating element contained in a packaging bag made of airtight material. The oxidation rate-controlling heating element is made of iron powder, etc., sealed in a breathable packaging material such as non-woven fabric or paper. Type of heating composition. When using the product, remove the packaging bag to expose the breathable packaging material. In the case of nonwoven fabrics, although it depends on the diameter and basis weight (mass per unit area) of the fiber, it is breathable because it is penetrated with pores of several μm to tens of μm. Although it varies depending on the size and use, the rated duration of about 12 to 20 hours is the mainstream. This rated duration refers to "the time during which temperatures above 40°C are maintained continuously." In most cases, 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. Therefore, when the current disposable heating pack is used normally and the speed is controlled by the characteristics of the breathable packaging material, the heating effect will disappear after half a day to less than a day, and it will be discarded.

However, for consumers who use multiple disposable heating packs every day when it is very cold, the disposal of the heating packs is troublesome and time-consuming, and the waste itself may be stressful. And more importantly, the increase in waste is inevitable for the environment.

Furthermore, the temperature of disposable heating packs, especially the temperature immediately after use, is usually too high for human skin. In order to use it comfortably, clothes or cloth other than clothes must be separated by equal layers. Between it and the skin, etc. to regulate temperature. Furthermore, since the temperature of the heat pack will drop after a few hours from the start of use, in order to continue using it comfortably, it is necessary to remove temperature-adjusting clothes, etc. The average temperature of disposable heating packs is 50~60°C. In this temperature range, even if the heating pack is indirectly in contact with the human body through clothing, etc., there is still the possibility of low-temperature burns. No matter how comfortable the user feels, if the disposable heating pack is always in close contact with the same area, the possibility of low-temperature burns increases. According to the Japanese Burn and Scald Society, low-temperature burns refer to "burns that can occur if the same part of the skin is touched for a long time, even at a comfortable mild temperature (44°C ~ 50°C)." In this way, in order for the disposable heating pack to be used safely and comfortably from the beginning to the end of use, it is dangerous and insufficient to keep it in close contact with the same part of the human skin in the same way.

The invention described in Patent Document 1 provides a disposable heating pack with an aluminum-processed film provided on a part so that the disposable heating pack can be used more effectively and comfortably for a longer period of time. Cover. By placing an aluminum-processed film on the side that is not in contact with the human body, it prevents the dissipation of heat from this side and reduces the air inflow from this side to reduce the chemical reaction speed of the heating pack, thereby making the heating pack last longer. Effect. However, in the invention described in Patent Document 1, because the material of the other side opposite to this side is cloth, the inflow of air cannot be controlled, and the effect of reducing the chemical reaction speed of the heating pack is not very effective. The cloth side of the heating pack cover described in Patent Document 1 is exposed to very fresh air immediately after use, making it difficult to suppress a rapid temperature rise of the heating pack.

The technical idea of the present invention can be modified in various ways within the technical scope defined by the claims described in the patent application.

(First Embodiment) As illustrated in FIG. 4 etc., the reaction restriction bag 1a according to the first embodiment of the present invention is a flexible, portable bag, and is provided with a flat outer bag 11a and a flat outer bag 11a accommodated in the outer bag 11a. The inner bag 21a. Furthermore, inside the inner bag 21a, the oxidation rate-controlled heating element 100, which controls the heat generation rate through an oxidation reaction, is stored in a use form. Generally, the oxidation rate-controlled heating element 100 as a commercial product, such as a well-known portable heating device such as a "disposable heating pack", is stored in a package made of an airtight material. Products in the form of bags appear in large numbers on the market. When using the product, the packaging bag must be removed to expose the breathable packaging material containing the oxidation rate-controlling heat-generating particles as the main body of heat generation. In this manual, the state in which the packaging bag of the product is removed and the breathable packaging material is exposed is called the "usage state". The double-layer bag structure including the outer bag 11a and the inner bag 21a is used to limit the conductance of oxygen supplied to the oxidation rate-controlling heating element 100, thereby suppressing the oxidation reaction of the oxidation-rate controlling heating element 100. As shown in FIG. 1 , the outer bag 11 a of the reaction limiting bag 1 a of the first embodiment has an opening at the upper end. As shown by the hidden line in FIG. 1 , like the outer bag 11 a , the inner bag 21 a also has an opening at the upper end. As shown in FIG. 1 , a plurality of oxygen supply holes 31 a are respectively provided on both the front and back sides of the outer bag 11 a , that is, the front sheet of the outer bag 11 a and the back sheet opposite to the front sheet. That is, the plurality of oxygen supply holes 31a penetrate the front sheet along the thickness direction of the front sheet. In addition, the plurality of oxygen supply holes in the back sheet of the outer bag 11a, although not shown in the figure, also penetrate the back sheet along the thickness direction of the back sheet. Similarly, although illustration is omitted, a plurality of oxygen supply holes are also provided on both the front and back sides of the inner bag 21a, that is, the front sheet of the inner bag 21a and the back sheet opposite to the front sheet. The hole penetrates the front sheet and the back sheet of the inner bag 21a along the respective thickness directions of the front sheet and the back sheet of the inner bag 21a.

In this specification, for convenience, the opening of the outer bag 11a is defined as the "first opening", and the opening of the inner bag 21a is defined as the "second opening". Similarly, the front sheet of the outer bag 11a is defined as the "first front sheet", the back sheet of the outer bag 11a is defined as the "first back sheet", the front sheet of the inner bag 21a is defined as the "second front sheet", and the back sheet of the inner bag 21a is defined as the "second back sheet". In the three-dimensional diagram of Figure 1, the first and second front sheets are arranged near the front side of the paper surface, and the first and second back sheets are arranged on the inside of the paper surface. In the following embodiments, modifications, embodiments, etc., the opening of the outer bag is also called the "first opening", and the opening of the inner bag is also called the "second opening". In the following embodiments, variations, embodiments, etc., the front sheet of the outer bag is referred to as the "first front sheet", the back sheet of the outer bag is referred to as the "first back sheet", the front sheet of the inner bag is referred to as the "second front sheet", and the back sheet of the inner bag is referred to as the "second back sheet".

As shown in Fig. 1 and Fig. 4, etc., the outer bag 11a constituting the reaction limiting bag 1a of the first embodiment has a flexible structure of "first bag shape", which has the first front sheet and the first back sheet as main components and has the first opening at the upper end. On the other hand, as shown in Fig. 1 and Fig. 4, etc., the inner bag 21a accommodated in the outer bag 11a has a flexible structure of "second bag shape", which has the second front sheet and the second back sheet as main components and has the second opening at the upper end. In Fig. 1, the first front sheet and the first back sheet are both rectangular and have the same shape, so the outer bag 11a has a flat rectangular bag shape. The first front sheet and the first back sheet have three sides other than the upper side of the four sides connected to each other, and the upper sides are not connected to each other, and play the role of the first opening. The same is true for the inner bag 21a.

As shown in FIG. 1 , a first joint portion (15a ₁ , 15a ₂ ) is provided near the center of the upper edge of each of the first front sheet and the first back sheet. The first joining portion (15a ₁ , 15a ₂ ) is composed of a rectangular first front joining piece 15a ₁ connected to the first front sheet side and a rectangular first back joining piece 15a ₂ connected to the first back sheet side . In Figures 1 and 4 to 6, the first front joining piece 15a ₁ is only fixed to the outside of the first front sheet. However, the illustrations in Figures 1 and 4 to 6 are only examples, and the first front joining piece 15a 1 can also be held It can be fixed in the form of a sheet, or it can be fixed only on the inside of the first front sheet, or it can be fixed in other styles. In addition, the shape of the first front joining piece 15a ₁ is a rectangular sheet in FIG. 1 etc., but it may be a polygonal shape other than a rectangular shape, a circle, an ellipse, etc., and any shape may be used. Regarding the fixing style and shape, the same applies to the first back surface joining piece 15a ₂ . The first joint portion (15a ₁ , 15a ₂ ) is a member for easily changing the outer bag 11a from the closed state to the open state. It may be a structure that is integrated with the first front sheet and the first back sheet respectively. Originally, the outer bag 11a does not necessarily need to be provided with the first joint portion.

As shown in FIG. 1 , the first opening and closing tool 13 a is provided on the outer bag 11 a near the first opening, that is, slightly below the upper edges of the first front sheet and the first back sheet. In FIG. 1 , only the first front sheet side is shown, but the first opening and closing tool 13 a is also provided at the same position on the first back sheet side. The "first opening" in this specification is defined as the portion from the top of each of the first front sheet and the first back sheet to the first opening and closing tool 13a in the outer bag 11a. When the first opening and closing tool 13a is disposed on each of the first front sheet and the first back sheet, the first opening is the first opening and closing tool 13a on each of the first front sheet and the first back sheet. The same applies to the following embodiments, modifications, examples, etc. That is, the first opening and closing tool 13a is an opening and closing tool that allows the first opening to be freely opened and closed. The first opening and closing tool 13a may be any type, such as a slide fastener or a slide fastener, as long as it can be opened and closed freely and can seal the first opening in a closed state. A zipper can be made into a quasi-sealed (quasi-sealed) state by fitting the male rail (male member) on one side with the female rail (female member) on the other side using your fingers. A zipper with a slider is one in which the convex rail and the concave rail can be fitted by moving the slider in one direction laterally. In both cases, in order to move from the closed state to the open state, the fitting of the male rail and the female rail only needs to be released. In addition, when the first opening and closing tool 13a is in the closed state, the "quasi-sealed" state of the first opening is purely focused on the first opening, as long as it restricts the conductance of the outflow and inflow of oxygen. The "intended to be sealed" state is sufficient, and does not refer to the "sealing (sealing)" of the outer bag 11a itself. Since the outer bag 11a has a plurality of oxygen supply holes such as a plurality of oxygen supply holes 31a provided therethrough, it is impossible to completely seal the outer bag 11a itself by the first opening and closing tool 13a. The same applies to the following embodiments, modifications, examples, etc.

In this specification, the "open state" of the first opening and closing tool 13a refers to a state in which part or all of the first opening and closing tool 13a is open, that is, a state in which the intended sealing state of the first opening is released. On the other hand, the "closed state" of the first opening and closing tool 13a refers to a state in which the first opening and closing tool 13a is completely closed, that is, a state in which the first opening is in a pseudo-sealed state. In this specification, "the first opening and closing tool 13a is in an open state" may be expressed in other ways such as the first opening being in an open state, or the outer bag 11a being in an open state, and all of them refer to the open state in the same way. The same idea applies to "closed states". The concepts of "open state" and "closed state" are also the same in the following embodiments, modifications, examples, etc.

The number of oxygen supply holes 31a provided in the first front sheet of the outer bag 11a shown in Figure 1. For example, in the outer bag 11a, when the width of the first front sheet is 16 cm, from the bottom edge to the first opening and closing device When the height of 13a is 19.5cm, it is preferably about 50 to 100 pieces, and more preferably 70 to 90 pieces. The shape of the plurality of oxygen supply holes 31a can be polygonal, circular or any shape. In the case of circular shapes, holes with a diameter of 0.1~3mm are preferred, and holes with a diameter of 1.6~3.0mm are more preferred. In the following explanation of this manual, the characteristic dimensions such as the maximum diagonal length of a two-dimensional figure that is equal to the area of a circle with a diameter of 0.1 to 3 mm are called "equivalent diameter Φ _eff 0.1 to 3 mm." Similarly, the characteristic size of a two-dimensional figure that has an area equal to that of a circle with a diameter of 1.6 to 3.0 mm is called "equivalent diameter Φ _eff 1.6 to 3.0 mm." For example, in the case of a square or a rectangle, the two diagonal lengths are equal because they are the maximum diagonal length. The maximum diagonal length that is equal to the area of a circle with equivalent diameter Φ _eff can be selected as the characteristic size. In the case of a regular pentagon, since the five diagonals are of equal length, the maximum diagonal length that is equal to the area of a circle with equivalent diameter Φ _eff can be selected as a characteristic dimension. In the case of a regular hexagon, there are three maximum diagonal lengths and six diagonal lengths shorter than the maximum diagonal length. Therefore, the maximum diagonal length is selected as the characteristic dimension. In the case of a regular heptagon, there are 8 maximum diagonal lengths and 6 diagonal lengths shorter than the maximum diagonal length. Therefore, the maximum diagonal length is selected as the characteristic dimension. In the case of an ellipse, the equivalent diameter calculated by (long radius) × (short radius) = (equivalent diameter/2) ² is selected as the characteristic size, and it can also be extended to ellipses.

If the equivalent diameter Φ _eff of the plurality of oxygen supply holes 31a greatly exceeds 3.0 mm, the amount of oxygen flowing in and out of the holes becomes too large. In this specification, in Fig. 1, the portion from the bottom edge of the first front sheet to the height of the first opening and closing tool 13a is defined as "the hole installation possible area", and the area of the entire hole installation possible area is defined as " Possible area for hole setting". Furthermore, when the possible hole installation area of the first front sheet is set to A ₁ and the total area of the plurality of oxygen supply holes 31a is set to ΣS ₁ , "the critical opening area ratio η ₁ of the first front sheet" is defined as . Under the condition of 20.95% oxygen concentration in the air (near the earth's surface), the critical opening area ratio η ₁ of the first front sheet defined by formula (1) is preferably about 0.02~2.5%, and more preferably the first front sheet is about 0.02~2.5%. The critical opening area ratio of the front sheet η ₁ = is about 0.1~1.0%. Even more preferably, the critical opening area ratio of the first front surface sheet η ₁ =0.11~0.83%. Regarding the plurality of oxygen supply holes provided in the first back sheet, the number, shape, equivalent diameter Φ _eff , critical opening area ratio, etc. are the same as those of the plurality of oxygen supply holes 31a in the first front sheet. The definitions of the equivalent diameter Φ _eff , the possible hole arrangement area, the possible hole arrangement area, the critical opening area ratio, etc. on the first front sheet and the first back sheet are the same in other embodiments, modifications, examples, etc. of.

The plurality of oxygen supply holes 31a shown in Fig. 1 may be neatly arranged at certain intervals as shown in Fig. 1 and others, or may not be neatly arranged. However, it is preferable that the plurality of oxygen supply holes 31a are distributed throughout the entire area where the holes can be installed, rather than being concentrated in a specific location. As long as the spacing between the plurality of oxygen supply holes 31a is within the range of the critical opening area ratio η ₁ =0.02~2.5% of the first front sheet under the condition of an oxygen concentration of 20.95% defined by equation (1), no matter Any level is fine. For example, in the outer bag 11a, it is preferable when the width of the first front sheet is 16cm, the height from the bottom edge to the first opening and closing tool 13a is 19.5cm, and the plurality of oxygen supply holes 31a are all equivalent diameters Φ _eff 1.6mm. The distance (pitch) between the plurality of oxygen supply holes 31a is about 1.5 to 3.0 cm, and the number of the plurality of oxygen supply holes 31a is about 25 to 90. Regarding the plurality of oxygen supply holes provided in the first back sheet, the concept of setting the pitch and the like is the same as that of the plurality of oxygen supply holes 31a. Furthermore, the positions of the plurality of oxygen supply holes provided in the first back sheet do not need to be consistent with the positions of the plurality of oxygen supply holes 31a provided in the first front sheet.

As the material of the first front sheet shown in Figure 1, any material that cannot penetrate oxygen and moisture in the air can be used: polyethylene film (PE film), polypropylene film (PP film), ethylene vinyl acetate Ester copolymer film (EVA film), biaxially stretched polypropylene film (OP film), PVDC resin coated OPP film (KOP film), non-stretched polypropylene film (CP film), nylon film (NY film), biaxially stretched film High gas barrier nylon film (gas barrier NY film), polyester film (PET film), transparent evaporated polyester film (transparent evaporated PET film), polyvinyl chloride film, etc. Also usable are laminated films obtained by laminating various films mentioned above, and aluminum vapor-deposited films obtained by vapor-depositing aluminum on various films. The thickness of the first front sheet can be any thickness such as 0.01 to 0.1 mm. The material and thickness of the first back sheet are the same as those of the first front sheet.

The first bag-shaped flexible structure of the outer bag 11a shown in FIGS. 1 and 4 may be any of a two-way sealing bag, a three-way sealing bag, a side sealing bag, a bottom sealing bag, and the like. As shown in FIG. 1 , the outer bag 11 a of the first embodiment does not have gussets on the bottom or side surfaces, but it may also have gussets on the bottom like a bottom gusset bag (gusset bag), a side gusset bag, etc. Or a type with gussets on the sides. When the outer bag 11a has a gusset at the bottom or side, a plurality of oxygen supply holes similar to the plurality of oxygen supply holes 31a may be provided in the gusset portion.

The inner bag 21a stored inside the outer bag 11d, as shown in FIGS. 1 and 4, has a second front sheet and a second back sheet as main components, and has a second opening at the upper end, and is connected to the outer bag. 11d together constitute the reaction limiting bag of the first embodiment of the double-layer bag structure. As shown by the hidden line in FIG. 1 , the second front sheet and the second back sheet are both rectangular and have the same shape, so the inner bag 21 a has a flat rectangular second bag shape. In the second front sheet and the second back sheet, three of the four sides other than the upper side are connected to each other, and the upper sides are not connected to each other, and function as the second opening.

As shown in FIG. 1 , a second joint portion (25a ₁ , 25a ₂ ) is provided near the center of the upper edge of each of the second front sheet and the second back sheet. The second joining portion (25a ₁ , 25a ₂ ) is composed of a rectangular second front joining piece 25a ₁ connected to the second front sheet side and a rectangular second back joining piece 25a ₂ connected to the second back sheet side. . In FIGS. 1 and 4 to 6 , the second front surface joining piece 25a ₁ is only fixed to the outside of the second front surface sheet. However, this illustration is an example, and the second front surface joining piece 25a 1 can also be fixed by holding the second front surface sheet. It can be fixed only on the inside of the second front sheet, or it can be in other styles. In addition, the shape of the second front joining piece 25a ₁ is a rectangular sheet in FIG. 1 and the like, but it may be a polygonal shape other than a rectangular shape, a circle, an ellipse, etc., and any shape may be used. Regarding the fixing pattern and shape, the same applies to the second back surface joining piece 25a ₂ . The second joint portion (25a ₁ , 25a ₂ ) is a member for easily changing the inner bag 21a from the closed state to the open state. It may also be a structure that is integrated with the second front sheet and the second back sheet. Originally, the inner bag 21a does not necessarily need to be provided with the second joint portion.

As shown in FIG. 1 , the second opening and closing tool 23 a is provided on the inner bag 21 a near the second opening, that is, slightly below the upper edges of the second front sheet and the second back sheet. In FIG. 1 , only the second front sheet side is shown, but the second opening and closing tool 23 a is also provided at the same position on the second back sheet side. The "second opening" in this specification is defined as the area from the upper edges of the second front sheet and the second back sheet to the second opening and closing tool 23a in the inner bag 21a in the same manner as the first opening. parts. When the second opening and closing tool 23a is disposed on each of the second front sheet and the second back sheet, the second opening is the second opening and closing tool 23a on each of the second front sheet and the second back sheet. The same applies to the following embodiments, modifications, examples, etc. That is, the second opening and closing tool 23a is an opening and closing tool that allows the second opening to be freely opened and closed. The second opening and closing tool 23a is, like the first opening and closing tool 13a, a slide fastener, a slide fastener, etc., as long as it can be opened and closed freely and the second opening can be partially sealed (quasi-sealed) in the closed state. Any type is acceptable. In addition, when the second opening and closing tool 23a is in the closed state, the state of "the second opening is intended to be sealed" is the same as the state of the first opening being intended to be sealed. When focusing purely on the second opening, as long as It suffices as a "quasi-sealing" state that restricts the conductance of oxygen inflow and outflow, and does not mean "sealing (sealing)" of the inner bag 21a itself. The inner bag 21a is the same as the outer bag 11a in that it has a plurality of oxygen supply holes penetrated therethrough, so it is impossible to completely seal the inner bag 21a itself with the second opening and closing tool 23a. In addition, the definitions of "open state" and "closed state" of the second opening and closing tool 23a in this specification are the same as those of the first opening and closing tool 13a. The same applies to the following embodiments, modifications, examples, etc.

Although not shown in FIG. 1 , the second front sheet and the second back sheet of the inner bag 21 a are each provided with a plurality of oxygen supply holes as through-holes similar to the plurality of oxygen supply holes 31 a.

Similar to the definition of the hole installation possibility area A ₁ , in this specification, the portion of the inner bag 21 a shown by the hidden line in FIG. 1 from the bottom edge of the second front sheet to the height of the second opening and closing tool 23 a It is defined as the "hole installation possibility area" of the second front surface sheet, and the area of the entire hole installation possibility area is defined as the "hole installation possibility area" of the second front surface sheet. For example, in the inner bag 21a, when the lateral width of the second front sheet is 11cm and the height from the bottom edge to the second opening and closing tool 23a is 19cm, the possible hole installation area is = 20,900mm ² , and the hole is provided in the second part of the inner bag 21a. The number of oxygen supply holes on the front sheet is preferably 10 to 100, more preferably 15 to 70. Furthermore, when the possible hole installation area of the second front sheet is set to A ₂ and the total area of the plurality of oxygen supply holes of the second front sheet is set to ΣS ₂ , "the critical opening area ratio η of the second front sheet ₂ " is defined as . Under the condition of 20.95% oxygen concentration in the air (near the earth's surface), the critical opening area ratio η ₂ of the second front sheet defined by formula (2) is preferably about 0.02~2.5%, and more preferably the second front-side sheet is about 0.02~2.5%.

As for the plurality of oxygen supply holes provided in the second front sheet and the second back sheet, similar to the plurality of oxygen supply holes 31a, they may or may not be neatly arranged at a certain pitch, but they are different from being concentrated in a specific location. Rather, it is better to spread the holes throughout the possible area. The plurality of oxygen supply holes provided in the second front sheet and the second back sheet do not necessarily have to coincide with the positions of the plurality of oxygen supply holes including the plurality of oxygen supply holes 31a provided in the outer bag 11a. The pitch between the plurality of oxygen supply holes provided in the second front sheet is within the range of the critical opening area ratio η ₂ =0.02~2.5% of the second front sheet defined by equation (2), no matter it is Any level is fine. Like the plurality of oxygen supply holes 31a, the pitch between the plurality of oxygen supply holes provided in the second front sheet is preferably about 1.5 to 3.0 cm. The same is true for the plurality of oxygen supply holes provided in the second back sheet.

As explained at the beginning, the reaction limiting bag 1a of the first embodiment accommodates the oxidation rate control heating element 100 inside the inner bag 21a as shown in FIGS. 2 to 4 and so on. First, as shown in FIG. 6 , both the outer bag 11 a and the inner bag 21 a are opened, and the oxidation rate-control heating element 100 is placed in the air layer of the inner bag 21 a, that is, the inner heat storage space 43 a. In FIGS. 4 to 6 , in order to simplify the illustration, the illustration of the plurality of oxygen supply holes including the plurality of oxygen supply holes 31 a is omitted. Also shown in FIGS. 4 to 6 are examples in which the inner bag 21a is slightly below the second opening and closing tool 23a, that is, fixed to the outer bag 11a by the inner bag fixing parts 51a and 51b. The oxidation rate-controlling heating element 100 contained in the reaction limiting bag 1a of the first embodiment only needs to be an oxidation-rate controlling heating element based on the oxidation reaction of oxygen in the transmitted air, and its raw materials are not limited.

In order to speed up the start-up of heat generation, there are also strips with a width of 3 to 5 cm to concentrate the pinholes. situation formed. The hole diameter and arrangement of the pinholes drilled into the breathable packaging material are determined so that the air permeability value based on the Gurley air permeability tester becomes 2~10 seconds/300cc. In addition, in FIGS. 4 to 6 , although the cross section of the oxidation rate control heating element 100 is shown to be an elongated oval shape with two tip portions, this is only an example, and it may be other than the oxidation rate control heating element 100 shown in FIGS. 4 to 6 . The cross-sectional structure of the instant heating element 100 is a flatter shape, etc. For example, when the oxidation rate-controlled heating element 100 is a portable heating device, it can be appropriately used in either a type that is adhered to clothing, etc., or a non-adhesive type. In the case of the adhesive type, the base paper may be peeled off so that the sticker part is exposed, or the base paper may be put into the inner bag 21a without peeling off. When a portable heating device is used as the oxidation rate controlling heating element 100, it can be taken out from the bag of non-breathable packaging material and immediately put into the inner bag 21a, or it can be taken out from the bag of non-breathable packaging material and then After gently kneading it with your hands, put it into the inner bag 21a.
