Among the parabens, methyl paraoxybenzoate is colorless crystals or white crystalline powder, odorless or slightly odorous. Although it has no taste, the tongue is paralyzed. 1 g of methyl paraoxybenzoate is about 400 ml of water at room temperature (saturated aqueous solution is slightly acidic. PH 4.3), about 50 ml of water at 80 ° C., about 2.5 ml of ethanol, about 10 ml of ether, about 40 m of warm oil.

The antibacterial action of parabens is stronger than that of acid in bacteriostatic action and effective against a very wide range of microorganisms. Fermentation-preventing power, fungal growth-preventing power and bactericidal action are far greater than those of carboxylic acid. It is also far less toxic than salicylic acid and benzoic acid. Parabens are widely used especially as preservatives and preservatives. However, coexistence with a nonionic surfactant may reduce efficacy. The amount used is usually about 0.1 to 0.2% by weight, but it is more effective to use two or more parabens in combination. Parabens are phenolic substances that are relatively insoluble in water, but soluble in propylene glycol. Further, the stability is good in a wide range of heat and hydrogen ion index (pH).

Next, among the polyols, propylene glycol is a hygroscopic, colorless and transparent viscous liquid, has almost no odor, and has a slight bitterness. Also,
The specific gravity is 1.036 to 1.040. It is mixed with water, ethanol, acetone and chloroform at an arbitrary ratio. Also, 1 g of propylene glycol is 6 ml of ether.

Propylene glycol is easily absorbed from the digestive organs, but transdermal absorption is minimal. About 50% of the dose is recovered from urine in about 24 hours, while the other 50%
Undergoes the same metabolism as carbohydrates or alcohol. Absorbed propylene glycol has the effect of increasing hepatic glycogen content, and part of it is used in the body as a substitute for dietary carbohydrate. The main pharmacological effect is central nervous system depression, like alcohol, but metabolism and excretion are much more gradual. It has a weak antifungal effect and a fermentation inhibitory effect similar to alcohol. The solubility, emulsifying property, wettability (moisturizing property), bactericidal property, softening property and the like of propylene glycol have great utility value in combination with being harmless to the human body. That is, when propylene glycol is blended in addition to well dissolving organic chemicals, water-soluble vitamins, fragrances, etc., it softens the skin without leaving stickiness and improves adhesion and spread. Very effective as an emulsifier and stabilizer.

Next, cetylpyridinium chloride is a white powder or crystal, has a slightly peculiar odor, and has a bitter taste. Originally developed as a detergent for fibers, it has a strong bactericidal power. This cetylpyridinium chloride is highly soluble in water, ethanol and chloroform. The hydrogen ion index (pH) of the aqueous solution when dissolved in water is 6.0 to 7.0 (extremely weak acidity or neutrality), and has surface activity. The chemical name is the same. Has bactericidal and deodorant effects. According to the main component of the chemical liquid and the ratio of the component concentrations thereof according to the above-mentioned example, even if the chemical liquid is impregnated or applied with the chemical liquid for a long time at a temperature of 35 ° C to 55 ° C, a wet wipe has a good wiping effect. Exert.

It decomposes by coloring at 00 ° C, and a little whitish soft ash remains when burnt. Furthermore, regarding the acid resistance of rayon, even if it is thin, it is attacked by strong acid when it is heated. If it is thick, the strength will decrease and it will decompose even if it is cold. After being in contact with a weak acid for a long time, it becomes stronger when it is hot. Good alkali resistance. It is generally resistant to organic solvents. In addition, when it is exposed to sunlight for a long time, its strength slightly decreases and it turns yellow. In addition, it is infested with mold. As mentioned above, rayon is said to be sensitive to acid. And, the above-mentioned chemical liquid comprising paraben, propylene glycol, cetylpyridinium chloride and water is acidic. However, most of this chemical solution is water, which is very thin and an extremely weak acid. Therefore, the deterioration of the nonwoven fabric made of rayon does not pose a problem in practical use.

FIG. 2 is a sectional view showing a case where the wet tissue is removed from the wet tissue heating apparatus 100 of FIG. The sponges 8 and 9 are for holding the wet tissue enclosing bag 10 by pressing the heater 5 from above and supporting it from below, and in a state where the wet tissue is removed, it is in an extended state inside the heating device main body 100. . The sponges 8 and 9 hold the wet tissue enclosing bag 10 and have a heat insulating effect.

FIG. 3 is an overall perspective view showing the outer lid 1, the enclosing bag 10 and the storage box 2 of the wet tissue heating apparatus of FIG. 1 separately. Here, in the wet tissue enclosing bag 10, the wet tissues 11 are laminated so that the end portions of the sheets have a relationship as shown in FIG. It has been stored.

FIG. 4 is an exploded perspective view showing the outer lid 1 of the wet tissue heating apparatus of FIG. 1 in an exploded manner. A taper 15 for returning dew condensation liquid is provided inside the wet tissue take-out port lid 3 so that the liquid that evaporates by heating and that is dewed on the back side of the lid 3 can be removed again from the wet tissue take-out hole 13 by the taper 15. It can be returned into the enclosing bag 10. By making the storage box 2 made of transparent polypropylene, the amount of wet tissue can be visually confirmed by the user.

Next, the operation of the embodiment of the wet tissue heating apparatus of the present invention shown in FIG. 1 will be described. When water is introduced from the water supply port 500, the water in the water supply section is set to gradually enter the thermochemical reaction chamber 502 at a predetermined ratio. The water supply unit 500 is provided with a valve for preventing the backflow of the liquid from the thermochemical chamber 502, but illustration and description thereof are omitted here. The thermochemical reaction chamber 502 is preliminarily filled with quick lime (CaO), and the water (H ₂ O) supplied from the water supply unit 500 and quick lime cause the following chemical reaction to generate heat. CaO + H ₂ O → Ca (OH) ₂ + 15.2K Cal
(Fever) Here, Ca (OH) ₂ is slaked lime (calcium hydroxide)
Is.

The heat generated by the production of slaked lime is transferred to the wet tissue sealing bag 10 through the metal plate 4. At this time, since water is gradually supplied at a predetermined rate as described above, heat is gradually generated, and the heating state is prolonged (1
Can be held for about a week). Therefore, the enclosed bag 1
The wet tissue (chemical solution filling base material) 11 in 0 is efficiently heated and kept warm. Therefore, it is possible to prevent the user from feeling uncomfortable when using the wet tissue.

Next, a second embodiment of the wet tissue heating apparatus of the present invention will be shown. FIG. 5 is a sectional view showing a state in which a wet tissue is put in the apparatus of this embodiment. Here, the same symbols are used for the same elements as in FIG. 1 and their explanations are omitted. In FIG. 5, a thermochemical reaction chamber 512 filled with pure iron powder (Fe) is formed in the heater 55. Although not shown, the thermochemical reaction chamber 512 is divided into a plurality of (for example, 7) chambers. In FIG. 5, two rooms are shown in this.

A plurality of holes 66 are formed in the upper part of the heater case 56 constituting the thermochemical reaction chamber 512, and correspondingly, a plurality of holes 600 are also formed in the sponge 58 and the outer lid 51. Has been. Hole 600 of outer lid 51
Are divided into a plurality of hole groups corresponding to a plurality of thermochemical reaction chambers 512. Then, seals (601, 602, ...) Are provided corresponding to the respective hole groups. For example, one hole group is closed like a seal 602 corresponding to an unused room. In addition, a seal corresponding to a certain hole group, such as the seal 601, is peeled off according to the room to be used. Now, thermochemical reaction chamber 512
Is filled with pure iron powder (Fe) in advance as described above, and when a certain group of holes is opened, the outside air is exposed to the thermochemical reaction chamber 51.
2, oxygen (O ₂ ) in the outside air supplied from the hole 600 and pure iron powder (Fe) undergo the chemical reaction shown below to generate heat. 2Fe + (3/2) O ₂ → Fe ₂ O ₃ + 195.2K
cal (heat generation) Here, Fe ₂ O ₃ is ferric oxide. Further, the ferric oxide and aluminum (Al) of the metal plate 4 cause the following chemical reaction to generate heat. Fe ₂ O ₃ + 2Al → Al ₂ O ₃ + 2Fe + 202.6
Kcal (heat generation) Here, Al ₂ O ₃ is alumina, and the progress of oxidation of aluminum naturally stops due to the corrosion resistance of alumina itself.

The heat generated by the production of ferric oxide and alumina is transferred to the wet tissue sealing bag 10 through the metal plate 4. Therefore, the wet tissue (chemical solution filling base material) 11 in the sealed bag 10 is efficiently heated and kept warm. Moreover, since only the room from which the seal is peeled off causes an exothermic reaction, heating can be performed at a necessary time. With the above heating action, it is possible to prevent the user from feeling uncomfortable when using the wet tissue.

FIG. 6 is a diagram showing an example (Z fold shape) of a method of folding a base material (nonwoven fabric) of a wet tissue. The Z-fold shape is
This is because the wet tissue is of a pop-up type (when one substrate is used, the next substrate is slightly exposed), and the usability for the user is improved. It is taken out in the direction of the arrow shown, and in the case of this embodiment, the tip of the next base material comes out a little from the wet tissue taking-out hole 13 of the wet tissue enclosing bag 10.

Next, an example of the constitution of the film material used for the enclosing bag of the wet tissue of this embodiment will be briefly described by taking two examples. In the first configuration example, polyethylene terephthalate K-coated on a portion other than the surface provided with the outlet of the base material from the surface layer to the inner layer when formed as an enclosing bag of the base material (nonwoven fabric or the like) of the wet tissue. , Aluminum foil (or aluminum vapor-deposited polyethylene terephthalate or aluminum vapor-deposited polyvinyl chloride),
It has a laminated film shape in which polyethylene (or polypropylene) is laminated in this order. In particular, aluminum foil (or aluminum vapor-deposited polyethylene terephthalate or aluminum vapor-deposited polyvinyl chloride) is provided only on the surface (for example, the upper surface) provided with the take-out port for the base material (for example, non-woven fabric) when formed as an enclosing bag (for the six surfaces). It is effective to provide up to three of them.) The thickness of aluminum is 500 Å or more at the outlet, and 17 μm or more at other portions.

For this reason, in the case of a wet tissue, when a heater is provided on the side where the substrate is taken out, from the surface where the substrate is taken out to the first to second sheets of the substrate inside the sealed bag. Has a better thermal conductivity than that of the other surface to the substrate. Therefore, the heating efficiency of the base material used is improved. The K coat means coating with vinyl acetate.

In the second configuration example, a film is formed by laminating Teflon or aluminum tape and polypropylene in this order from the surface layer to the inner layer when formed as a base material enclosing bag. In particular, aluminum tape (at least a part of which is coated with pressure-sensitive adhesive made of acrylic acid ester-based or rubber-based adhesive) has an outlet for a base material (for example, non-woven fabric) when formed as a sealed bag. It is provided only on the provided surface (for example, the upper surface) (of the six surfaces, it is effective to provide up to three surfaces). Further, Teflon is provided on the periphery of the surface of the base material provided with the ejection port and on the surface where the ejection port is not provided. The thickness of aluminum on the aluminum tape is set to 0. so that wrinkles do not occur when the heating means (heater) comes into contact.
About 1 mm is selected.

For this reason, in the case of a wet tissue, when a heating means (heater) is provided on the side of the outlet of the base material, the first to The thermal conductivity to the second sheet is better than the thermal conductivity from the other surface to the substrate. Therefore, the heating efficiency of the base material used is improved. The sealed bag using this second configuration example can be used in a microwave oven (heating means).

As a method for producing a wet tissue,
An example of the manufacturing method as shown in FIG. 7 can be considered. FIG. 7 is a schematic view of a method of manufacturing a wet tissue. In this figure, in the first step, the step A for the film material 701 and the step B for the aluminum tape 721 are carried out at the same timing. First, as the process A for the film material 701,
The airtight film material 701 is the film material roll 7
Supplied from 10. The film material 701 is provided with register mark portions 708 on both sides, and the supplied film material 701 has a hole 712 formed by a press blade 711 at the center of the register mark portion 708.

On the other hand, in the step B for the aluminum tape 721, as the first step B1, the aluminum tape 721 is supplied from the aluminum tape roll 720. here,
The sheet supplied with the aluminum tape 721 attached in the center has register mark portions 709 on both sides thereof. This aluminum tape 721 is a perforated cut portion 70 which is a perforated cut of a predetermined shape at a portion which becomes a take-out opening portion 702 of a sealed bag by a press blade 722.
3 is provided.

Then, in the second step B2, the opening / closing lid 70
5 is supplied from the open / close lid roll 724, and the aluminum tape 7
An opening / closing lid 705 (having a small size that does not deviate from the area of the aluminum tape 721) having a pressure-sensitive adhesive layer (not shown) so as to cover the perforated cut portion 703 of 21 is attached member 723. Affixed by In the third step B3, the opening / closing lid 70 is opened by the heat sealer 713.
A fixed end 704 of the opening / closing lid, which is one end of 5, is provided. Here, the fixed end 704 of the opening / closing lid is welded to the aluminum tape 721. By this third step B3, the lid portion 72
6 has been produced.

In step C1 where the above two flows are combined, the lid portion 726 manufactured in the third step B3 is placed on the film material 701 manufactured in the step A and having the hole 712. And is attached by the attaching member 725.
At this time, the hole 712 is covered by the lid 726. In the next step C2, the film material 701 to which the lid portion 726 is attached is turned upside down, and the base material (for example, laminated non-woven fabric) 714 filled with the chemical solution is changed to the film material 70.
Can be placed on 1. In this case, the base material 714 is placed on the ejection port 702 on the surface opposite to the surface of the film material 701 to which the lid 726 is attached.

In the step C3 subsequent to the step C2, the bag-making process is performed by using a normal bag-making machine so that the film material 701 wraps around the base material 714. For example, the film material 701 is guided by the guide member 715, and the base material 714 is wrapped with the film material 701. Then, both side edges of the film material 701 are welded to each other by the heat sealer 716 to close the longitudinal opening of the film material 701 to manufacture the center seal portion 706. Further, the opening in the lateral direction of the film material 701 is closed by a heat sealer 717 to produce the end seal portion 707. Next, the film material 701 is cut to a fixed size by the hot blade 718. As a result, if it is inverted, a wet tissue with the lid 726 on the upper surface is manufactured.

In the above manufacturing method example, the film material 7 is used.
The heat resistance in the thickness direction of the aluminum tape 721 is set to be smaller than the heat resistance in the thickness direction of 01. Moreover, in the manufacturing method example of the present embodiment, the process B2 and the process B3 are performed.
As described above, the case where the opening / closing lid 705 is attached to the aluminum tape 721 has been described, but the aluminum tape 721 having the perforated cut portion 703 manufactured in step B1 is described.
Is attached to the film material 701 in step C1, and then the opening / closing lid 705 is placed on the film material 701 and the aluminum tape 721 so that one end overlaps with the film material 701, and the place where it overlaps with the film material 701 by the heat sealer 713. Alternatively, the fixed end 704 'of the opening / closing lid can be manufactured by welding. In this case, the opening / closing lid 705 when used
The metal plate (heating plate) of the heating device opens and closes when the
05 (particularly the position of the fixed end 704) is not contacted, and the heating effect is improved.

On the other hand, as the base material 714, the one previously filled with the chemical liquid is used, but it is also possible to use the one not filled with the chemical liquid and to inject the chemical liquid before the welding and sealing by the heat sealer 717. In this case, even if the chemical solution flows to some extent, it is absorbed by the next base material and does not flow out to other parts.

Next, an example of a method for producing the chemical liquid used in this embodiment will be described. First, in the first step, as parabens that are sparingly soluble in water, white crystalline powders such as methyl paraoxybenzoate, ethyl paraoxybenzoate, and propyl paraoxybenzoate are sequentially stirred little by little, respectively, in propylene glycol. It is put in and dissolved (for example, it is effective to set ethyl paraoxybenzoate 0.15% by weight, propyl paraoxybenzoate 0.05% by weight, and methyl paraoxybenzoate 0.03% by weight).
As a result, the first stock solution was produced. In addition, since the amount of water of crystallization is small in the crystalline powder, the manufacturing accuracy is high.

In the second step (regardless of the temporal relationship with the first step), powdery cetylpyridinium chloride (which has a small amount of water of crystallization), which is well soluble in water, is put into stirred water. Melt. As a result, the second stock solution was produced. In the third step, the above-mentioned first stock solution is added little by little to the second stock solution which is manufactured and stirred in the second step and mixed. As a result, paraben is about 0.2
By weight, a chemical solution of about 9% by weight of propylene glycol, about 0.2% by weight of cetylpyridinium chloride and about 91% by weight of water can be prepared.

According to the above-mentioned manufacturing method example, the chemical solution can be manufactured uniformly. In the first step, if propylene glycol is warmed (for example, the temperature is about 40 ° C.), it is more effective. Furthermore, in the second step, it is more effective if the water is warmed (for example, the temperature is about 40 ° C.) (the dissolution time is shortened).
