  In recent years, consumer awareness regarding beauty has improved, and there is a need for pack materials that not only promote blood circulation of the skin but also exert further beauty effects.

  Therefore, the present inventor has focused on hydrogen gas, which is said to remove active oxygen that causes skin aging. Further, the present invention has been completed by intensively studying a pack material capable of allowing carbon dioxide gas and hydrogen gas to act on the skin more effectively than simply bringing carbon dioxide gas and hydrogen gas into contact with the skin.

  That is, in the sheet-like pack material of the present invention, a powdery carbon dioxide generating agent that generates carbon dioxide by contact with water is dispersedly arranged on one side of the water-permeable and breathable separating layer, On the other side of the layer, a powdered hydrogen gas generating agent containing a hydrogen generating material that generates hydrogen gas by contact with water and a powdered acid material are dispersed, and the other of the isolation layer A water-permeable and breathable first protective layer that is used in contact with the skin is provided on the surface side, and hydrogen gas generation from when the hydrogen gas generating agent comes into contact with water until hydrogen gas is generated The time is longer than the carbon dioxide generation time from when the carbon dioxide generating agent comes into contact with water until carbon dioxide is generated.

According to the sheet-like pack material of the present invention, the hydrogen gas generation time from when the hydrogen gas generating agent comes into contact with water until it generates hydrogen gas is generated after the carbon dioxide generating agent comes into contact with water. It is longer than the carbon dioxide generation time until it is made to occur. For this reason, when the sheet-like pack material is wetted with water such as lotion, carbon dioxide gas is first generated to promote blood circulation of the skin, and hydrogen gas comes into contact with the skin later. For this reason, hydrogen gas penetrates into the blood well from the skin with increased blood circulation, and can act on the active oxygen in the body more effectively. For this reason, the high hydrogenation effect can be acquired by utilizing the generated hydrogen gas without waste.
In order to make the hydrogen gas generation time longer than the carbon dioxide generation time as described above, in the sheet-like pack material of the present invention, an acid material is provided so that the carbon dioxide generator can quickly generate carbon dioxide when wet. It has been. However, the acid material and the carbon dioxide generating agent are arranged on the opposite surface side with a separating layer so that the carbon dioxide generating agent does not absorb moisture during storage and the carbon dioxide generating agent does not generate carbon dioxide.
As described above, according to the present invention, in addition to the effect of promoting the blood circulation of the skin by carbon dioxide gas, a high cosmetic effect can be obtained by contacting the hydrogen gas with the skin promoted by the blood circulation.

It is a top view of a sheet-like pack material. It is sectional drawing of a sheet-like pack material. It is a schematic diagram of a hydrogen gas generating agent.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and redundant description will be appropriately omitted.
The components of the present invention do not have to be independent of each other, a plurality of components are formed as a single member, a single component is formed of a plurality of members, a certain configuration It is permitted that an element is a part of another component, a part of a certain component overlaps a part of another component, and the like.

  FIG. 1 is a plan view schematically showing the sheet-like pack material 100. 2 is a cross-sectional view taken along the line II-II in FIG. 1, and is a cross-sectional view of the sheet-like pack material 100. First, an outline of the sheet-like pack material 100 of the present embodiment will be described.

  In the following description, the vertical direction in FIG. 2 may be described as the vertical direction of the sheet-like pack material 100, but this is the relative position of the isolation layer 10, the first protective layer 20, and the second protective layer 30. This is to explain the relationship for the sake of convenience, and does not necessarily mean up and down in the direction of gravity when the sheet-like pack material 100 is manufactured or used. Moreover, the side in which the 1st protective layer 20 is provided among the sheet-like pack materials 100 may be called a back surface or a lower surface, and the side in which the 2nd protective layer 30 is provided may be called a surface or an upper surface.

The sheet-like pack material 100 of the present embodiment is configured by laminating the isolation layer 10, the first protective layer 20, and the second protective layer 30 with each other.
The isolation layer 10 is a layer having water permeability and air permeability. A carbon dioxide gas generating agent 12 is dispersedly arranged on one side of the isolation layer 10, and a hydrogen gas generating agent 14 and a powdered acid material 16 are distributed on the other side of the isolation layer 10. The carbon dioxide generating agent 12 is a powdery agent that generates carbon dioxide by contact with water. The hydrogen gas generating agent 14 is a powdery agent containing a hydrogen generating substance 14a that generates hydrogen gas by contact with water. The first protective layer 20 is a water-permeable and air-permeable layer used in contact with the skin, and is provided on the other surface side of the isolation layer 10.
In the sheet-like pack material 100 of the present embodiment, the hydrogen gas generation time from when the hydrogen gas generating agent 14 comes into contact with water to generation of hydrogen gas is the carbon dioxide after the carbon dioxide generating agent 12 comes into contact with water. It is characterized by being longer than the carbon dioxide generation time until the gas is generated.

Hereinafter, this embodiment will be described in more detail.
The sheet-like pack material 100 is a skin care product that is used by being attached to the surface of the user's skin in a wet state. The liquid that wets the sheet-like pack material 100 is an aqueous liquid, and may be lotion as well as hot water or water. Hereinafter, for simplicity, the liquid is generically referred to as “water”.
The sheet-like pack material 100 is enclosed in a packaging bag (not shown) in a dry state and provided to the user. The user opens the packaging bag, takes out the sheet-like pack material 100, wets it with water, and uses the first protective layer 20 in contact with the skin.

As shown in FIG. 1, the sheet-like pack material 100 of the present embodiment is used by being attached to the face, and thus has an elliptical shape, an oval shape, or the like in plan view.
A plurality of through-holes 102 are formed in the sheet-like pack material 100, and incisions 104 are formed at a plurality of locations. The through hole 102 is formed at a position corresponding to the user's eyes and mouth. By forming the through holes 102 in the sheet-like pack material 100, there is no problem in visual, breathing, conversation, etc. when the sheet-like pack material 100 is stuck on the face. The notch 104 is formed at the approximate center of the sheet-like pack material 100 for causing the sheet-like pack material 100 to follow the protruding shape of the nose, and is formed around the sheet-like pack material 100 and has a substantially spherical shape. There is one for causing the sheet-like pack material 100 to follow the face of the shape. By forming the cut portion 104 in the sheet-like pack material 100, the sheet-like pack material 100 can be brought into close contact with the three-dimensional shape of the human face.

The sheet-shaped pack material 100 has an index portion 106. The indicator unit 106 is used by contacting the user's skin with the other side (the lower side in FIG. 2) where the hydrogen gas generating agent 14 and the powdered acid material 16 are mixed and arranged. ) Is an index indicating that. The indicator 106 may be an indicator for the user to identify the front and back surfaces of the sheet-like pack material 100.
The indicator part 106 of this embodiment is formed on the upper surface of the second protective layer 30 corresponding to the upper surface side in FIG.
The fact that the back surface of the sheet-shaped pack material 100 is used in contact with the skin is described in a packaging bag or a manual (not shown) of the sheet-shaped pack material 100 and the front surface side of the sheet-shaped pack material 100. An indicator unit 106 may be provided. The specific mode of the indicator unit 106 is not particularly limited, and may be a figure, a symbol, or a color in addition to a character (TOP) indicating that it is on the front side as shown in FIG. Accordingly, the user can recognize that the side on which the index portion 106 is not formed should be used by contacting the skin.

Instead of the present embodiment, an indicator portion 106 may be provided on the lower surface of the first protective layer 20 corresponding to the back surface of the sheet-like pack material 100 to indicate that the surface is the back surface side.
The indicator portion 106 may be formed by printing on the second protective layer 30 or the first protective layer 20, and may be unevenly formed by embossing. In addition, the second protective layer 30 and the first protective layer 20 may be formed. The front and back surfaces of the sheet-like pack material 100 may be identifiable by forming different colors. In this case, the color indicating the second protective layer 30 or the first protective layer 20 corresponds to the indicator portion 106.

As shown in FIG. 2, the sheet-like pack material 100 has a first protective layer 20 laminated on the lower surface side (the other surface side) with the isolation layer 10 in between, and a water-permeable second material on the upper surface side (the one surface side). A protective layer 30 is laminated.
The hydrogen gas generating agent 14 and the acid material 16 are provided between the isolation layer 10 and the first protective layer 20. The sheet-like pack material 100 may be formed by supporting the hydrogen gas generating agent 14 and the acid material 16 on the lower surface of the isolation layer 10 and bonding the first protective layer 20 to the lower surface side of the isolation layer 10. Alternatively, the sheet-shaped pack material 100 may be formed by supporting the hydrogen gas generating agent 14 and the acid material 16 on the upper surface of the first protective layer 20 and bonding the isolation layer 10 to the upper surface side of the first protective layer 20. Good. Note that the hydrogen gas generating agent 14 and the acid material 16 are not necessarily arranged in the same layer. As will be described later, the isolation layer 10 may be composed of a plurality of layers, and the hydrogen gas generating agent 14 and the acid material 16 may be arranged in different layers. That is, it is only necessary that the hydrogen gas generating agent 14 and the acid material 16 be disposed on the opposite side of the carbon dioxide generating agent 12 from the uppermost isolation layer 10.

  In the sheet-like pack material 100 of the present embodiment, a water-soluble thickener 18 is selectively disposed on the upper surface side (one surface side) of the isolation layer 10. The thickener 18 is mixed with the carbon dioxide generator 12 and disposed. That is, the thickener 18 is not substantially disposed on the lower surface side of the isolation layer 10 and is disposed only on the upper surface side.

  The carbon dioxide generator 12 and the thickener 18 are provided between the isolation layer 10 and the second protective layer 30. The sheet-like pack material 100 may be formed by supporting the carbon dioxide generator 12 and the thickener 18 on the upper surface of the isolation layer 10 and then bonding the second protective layer 30 to the upper surface side of the isolation layer 10. Alternatively, the carbon dioxide generator 12 and the thickener 18 are supported on the upper surface of the second protective layer 30 and then the isolation layer 10 is joined to the lower surface side of the second protective layer 30 to form the sheet-shaped pack material 100. Also good.

The first protective layer 20 and the second protective layer 30 can use the same or different sheet materials. In this embodiment, a nonwoven fabric made of cotton fibers such as natural cotton can be used for the first protective layer 20 and the second protective layer 30. In particular, since the first protective layer 20 is a layer in contact with the user's skin, a spunlace nonwoven fabric can be preferably used from the viewpoint that the flexible first protective layer 20 can be formed without using a binder. The first protective layer 20 or the second protective layer 30 may be made of synthetic fibers such as polyester fibers instead of cotton fibers. The basis weight of the first protective layer 20 and the second protective layer 30 can be about 20 g / m ² or more and 50 g / m ² or less from the viewpoint of water absorption.

  The first protective layer 20 and the second protective layer 30 are water-permeable layers, and the first protective layer 20 and the second protective layer 20 are obtained by immersing the sheet-shaped pack material 100 in water or bringing the sheet-shaped pack material 100 into contact with running water. Water penetrates into the sheet-shaped pack material 100 through the two protective layers 30.

The isolation layer 10 restricts the particulate carbon dioxide generating agent 12, the hydrogen gas generating agent 14, and the acid material 16 from moving to the opposite side through the isolation layer 10, and allows the passage of water and gas. Is a layer. The isolation layer 10 of this embodiment is a single layer.
The isolation layer 10 includes a nonwoven fabric in which resin fibers made of a thermoplastic resin material such as polyolefin exemplified by polyethylene and polyester exemplified by polyethylene terephthalate (PET) are entangled, specifically, resin fibers. A thermal bond non-woven fabric fused by heat treatment can be preferably used. Thereby, the isolation layer 10 is fused to the first protection layer 20 and the second protection layer 30 simply by laminating the first protection layer 20, the isolation layer 10 and the second protection layer 30 and heating and pressing. The sheet-like pack material 100 can be easily laminated and integrated.

  The isolation layer 10 has higher water permeability than both the first protective layer 20 and the second protective layer 30. The gap between the fibers constituting the isolation layer 10 is larger than the gap between the fibers constituting the first protective layer 20 and the second protective layer 30. Thereby, the water which permeated from the 1st protective layer 20 and the 2nd protective layer 30 distribute | circulates through the isolation | separation layer 10 to an other side rapidly as shown by the white arrow in FIG. As a result, the carbon dioxide generating agent 12 and the acid material 16 dissolved in water are in good contact with each other and react to generate carbon dioxide.

  In the hydrogen gas generating agent 14 of the present embodiment, the hydrogen generating material 14a is covered with the water-soluble film 14b. In particular, regarding the hydrogen gas generating agent 14 of the present embodiment, the water-soluble coating 14b covers the entire surface of the hydrogen generating substance 14a as will be described in detail later. For this reason, when the water impregnated into the sheet-like pack material 100 and the hydrogen gas generating agent 14 come into contact with each other, the water-soluble coating 14b is first dissolved in water, and then the hydrogen generating substance 14a is dissolved in water to generate hydrogen gas. That is, even when the hydrogen generating substance 14a comes into contact with water, hydrogen gas is not generated immediately, so that the hydrogen gas generation time can be extended. In addition, by providing the water-soluble coating 14b, even when the hydrogen gas generating agent 14 absorbs moisture during storage of the sheet-like pack material 100, the reaction between the hydrogen generating substance 14a and water (humidity) is suppressed. Gas is not generated.

  The first protective layer 20 has water permeability and air permeability, and both carbon dioxide gas generated from the carbon dioxide generator 12 and hydrogen gas generated from the hydrogen gas generator 14 pass through the first protective layer 20. Contact with the user's skin. The second protective layer 30 may or may not have air permeability. In this embodiment, since the same kind of nonwoven fabric is used for the first protective layer 20 and the second protective layer 30, the second protective layer 30 also has air permeability. The carbon dioxide gas generated from the carbon dioxide generator 12 can be dissipated through the second protective layer 30 to the upper surface side of the sheet-like pack material 100, that is, the side opposite to the user's skin. In this embodiment, this dissipation is reduced. The carbon dioxide generator 12 and the thickener 18 are mixed and arranged on the surface side (one surface side) of the isolation layer 10. As a result, the thickener 18 dissolves in water and forms a gel in parallel with the carbon dioxide generator 12 dissolving in water and reacting with the acid material 16. Since the presence of the gel suppresses the carbon dioxide gas from reaching the second protective layer 30, the amount of carbon dioxide gas that passes through the first protective layer 20 is greater than the amount of carbon dioxide gas that passes through the second protective layer 30. More.

  The same applies to the hydrogen gas generated from the hydrogen gas generating agent 14, and the hydrogen gas is blocked from reaching the second protective layer 30 by the gelled thickener 18, and the hydrogen gas is exclusively contained in the first protective layer 20. To contact the user's skin. In particular, the hydrogen gas generation time from when the hydrogen gas generating agent 14 comes into contact with water until hydrogen gas is generated is longer than the time until the thickener 18 dissolves in water and transitions to a gel state. For this reason, when the hydrogen gas is generated, the gel-like thickener 18 is distributed in layers between the second protective layer 30 and the isolation layer 10, and the hydrogen gas generated from the hydrogen gas generator 14 is the second. Dissipation from the protective layer 30 into the air is well prevented.

  In order to further suppress the carbon dioxide gas and hydrogen gas from passing through the second protective layer 30 and dissipating into the air, an overmask (not shown) may be provided on the upper surface of the second protective layer 30. The overmask can be made of a sheet material having lower air permeability than the second protective layer 30. The overmask may be joined integrally with the second protective layer 30, or may be provided separately from the sheet-like pack material 100 and used in a non-joined manner with the second protective layer 30.

  Hereinafter, the carbon dioxide gas generating agent 12, the hydrogen gas generating agent 14, the acid material 16, and the thickener 18 constituting the sheet-like pack material 100 will be described in detail. These are all in the form of powder and are dispersed and supported on the sheet-like pack material 100. Here, the powder form widely means a particulate form, and the particle diameter is not particularly limited. The powder form includes various forms such as powder form, granule form or powder form. The average particle sizes of the carbon dioxide gas generating agent 12, the hydrogen gas generating agent 14, the acid material 16 and the thickener 18 may be different from each other.

  Carbonate can be used for the carbon dioxide gas generating agent 12, and specifically, sodium hydrogencarbonate and sodium carbonate can be used.

  The hydrogen gas generating agent 14 is a powder containing a hydrogen generating substance 14a capable of generating hydrogen gas by contact with water. The particle size (longest diameter) of the hydrogen gas generating agent 14 is in the range of 0.01 mm to 3 mm, preferably in the range of 0.05 mm to 1 mm, more preferably in the range of 0.1 mm to 0.5 mm. Range. The particle diameter of the powder is measured in accordance with JIS Z 8815: 1994 “General Rules for Screening Test Methods”.

Examples of the hydrogen generating substance 14a include metals such as magnesium, calcium, calcined calcium, uncalcined calcium or aluminum; metal hydrides such as magnesium hydride, calcium hydride, silicon hydride or barium hydride; metalloids such as germanium; Examples of silicic acid, silicic acid anhydride, aluminum silicate, silicic acid-based materials such as silica-absorbed hydrogen in which hydrogen is embedded in silicon dioxide or silicon oxide; minerals such as germanium, or combinations of two or more selected from these be able to. Of these, magnesium or magnesium hydride can be particularly preferably used as the hydrogen generating substance 14a.
The hydrogen generating substance 14a includes not only those that rapidly generate hydrogen when contacted with water, but also those that generate hydrogen due to the presence of an acid together with water.

  The water-soluble coating 14b is made of, for example, a water-soluble compound such as polyethylene glycol (PEG), polyvinyl pyrrolidone (PVP), hydroxypropyl cellulose (HPC) or sugar; a water-soluble excipient such as lactose, starch or corn starch, or these Mention may be made of mixtures.

  The mass of the water-soluble coating 14b in the hydrogen gas generating agent 14 is not particularly limited, but the mass of the water-soluble coating 14b is preferably 1% by mass or more and 10% by mass or less with respect to the mass of the hydrogen gas generating agent 14. That is, the hydrogen gas generating agent 14 generates hydrogen gas before the generation of carbon dioxide gas by the reaction of the carbon dioxide generating agent 12 and water is completed, so that the carbon dioxide gas and hydrogen gas synergistically affect the skin. Can bring. As described above, by covering the hydrogen generating material 14a with a small amount of the water-soluble film 14b, the hydrogen gas generation time from when the hydrogen gas generating agent 14 comes into contact with water until hydrogen gas is generated becomes excessive. Is prevented. From the viewpoint of coating the hydrogen generating material 14a with a small amount of the water-soluble coating 14b, PEG is particularly suitable as the water-soluble coating 14b.

As shown in FIG. 3, the hydrogen gas generating agent 14 is configured by covering a hydrogen generating substance 14a with a water-soluble film 14b. More specifically, the hydrogen generating substance 14a is coordinated with an acid substance 14c. A metal complex (hydrocluster) 14m is formed. The water-soluble film 14b includes the metal complex 14m unexposed. That the metal complex 14m is not exposed means that the entire outer periphery of the metal complex 14m is covered with the water-soluble coating 14b and the metal complex 14m is not substantially exposed on the surface of the hydrogen gas generating agent 14. .
Since the hydrogen generating substance 14a is coordinated with the acid substance 14c to form the metal complex 14m, the acid substance 14c is present in the vicinity of the hydrogen generating substance 14a. Therefore, at the same time that the water-soluble film 14b is dissolved in water and the hydrogen generating material 14a comes into contact with water, the acid material 14c is dissolved in water and supplies hydrogen ions around the hydrogen generating material 14a. For this reason, the hydroxyl group produced by the reaction of the carbon dioxide generating agent 12 such as sodium hydrogen carbonate with water flows into the lower surface side through the isolation layer 10 and the interior of the sheet-like pack material 100 is entirely basic. Even so, since hydrogen ions are supplied from the acid substance 14c in the immediate vicinity of the hydrogen generating substance 14a, the surroundings of the hydrogen generating substance 14a can be maintained locally acidic. For this reason, the hydrogen generating substance 14a reacts well with water to generate hydrogen gas.

  The hydrogen gas generation time (hydrogen gas generation start time) from when the hydrogen gas generating agent 14 comes into contact with water to generation of hydrogen gas is preferably 3 seconds or more and 30 seconds or less. On the other hand, the carbon dioxide generation time (carbon dioxide generation start time) from when the carbon dioxide generating agent 12 comes into contact with water until carbon dioxide is generated is shorter than the hydrogen gas generation time and is 0.1 seconds or more and 5 It can be less than a second.

  Acidic substances 14c include citric acid, aconitic acid, malic acid, acetic acid, fumaric acid, maleic acid, adipic acid, malonic acid, succinic acid, succinic anhydride, oxalic acid, tartaric acid and other organic acids; or dihydrogen citrate Metal salts of the above organic acids such as sodium can be used. These organic acids and metal salts of organic acids may be used in combination.

In the metal complex 14m, when the total amount of the metal or metal hydride constituting the hydrogen generating material 14a is converted to a metal salt, a larger amount of the acid material 14c than neutralizing the metal generating material 14a is more than the hydrogen generating material 14a. And are preferably coordinated with each other. That is, the metal salt formed by the reaction of the metal constituting the hydrogen generating material 14a or the metal hydride with water is an m-valent salt (molar equivalent (X / m)) with a molar mass X, and the hydrogen generating material 14a When the acid substance 14c to be coordinated is an n-valent acid (molar equivalent (Y / n)) with a molar mass Y, the following formula (1) is preferably satisfied.
Molar equivalent of acid substance 14c (Y / n)> Mole equivalent of salt of hydrogen generating substance 14a (X / m) (1)

  The hydrogen gas generating agent 14 may be composed of only the metal complex 14m and the water-soluble coating 14b, but may optionally contain an additive 14d as another component as shown in FIG. As the additive 14d, a material that promotes a skin care effect on the user's skin can be used, and examples thereof include antioxidant substances such as ascorbic acid or derivatives thereof, carotenoids, polyphenols, and coenzyme Q10.

As the acid material 16 dispersedly arranged with the hydrogen gas generating agent 14 on the back surface side of the isolation layer 10, the organic acid exemplified above or a metal salt of an organic acid is used as the acid substance 14c coordinated with the hydrogen generating substance 14a. Can do. The acid material 16 may be the same material as the acid substance 14c or a different material. Specifically, citric acid or sodium dihydrogen citrate can be preferably used as the acid material 16.
The presence of the acid material 16 in the sheet-like pack material 100 prevents the carbon dioxide generator 12 from being dissolved in water, thereby suppressing the inside of the sheet-like pack material 100 from being basic, and the sheet-like pack material 100 is applied. It is prevented that excessive irritation is given to the skin.

  A wide variety of water-soluble polysaccharides can be used for the thickener 18. For example, xanthan gum, guar gum, cellulose derivative or hyaluronic acid can be mentioned, and more specifically, carboxymethyl cellulose sodium (cellulose gum) which is a water-soluble cellulose derivative can be preferably used.

  In the sheet-like pack material 100 of the present embodiment, the total mass of the carbon dioxide generating agent 12 and the acid material 16 is preferably larger than the total mass of the hydrogen gas generating agent 14. Specifically, the total mass of the carbon dioxide generating agent 12 and the acid material 16 can be 50% or more and 90% or less of the total mass of the carbon dioxide generating agent 12, the acid material 16 and the hydrogen gas generating agent 14. Thereby, after sufficiently enhancing the blood circulation promoting effect of carbon dioxide gas, a high cosmetic effect can be given to the skin by the synergistic effect of hydrogen gas and carbon dioxide gas.

  The mass of the thickener 18 is preferably 5% or more with respect to the total mass of the carbon dioxide generator 12 and the acid material 16. By setting the mass of the thickener 18 to the above lower limit value or more, the carbon dioxide gas and the hydrogen gas are favorably suppressed from being dissipated in the air through the second protective layer 30, and the carbon dioxide gas and the hydrogen gas are applied to the skin. Can be supplied for a long time. The upper limit of the mass of the thickener 18 relative to the total mass of the carbon dioxide generator 12 and the acid material 16 is not particularly limited, but can be 70% or less.

The present invention is not limited to the above-described embodiment, and includes various modifications and improvements as long as the object of the present invention is achieved.
In the said embodiment, although the sheet-like pack material 100 of the three-layer structure by which the 1st protective layer 20 and the 2nd protective layer 30 were laminated | stacked on both sides of the isolation layer 10 was illustrated, this invention is not limited to this. For example, another isolation layer may be laminated on the lower surface side of the isolation layer 10, and the layer in which the hydrogen gas generating agent 14 is disposed and the layer in which the acid material 16 is disposed may be separate layers. That is, the hydrogen gas generating agent 14 and the acid material 16 need not be mixed with each other and arranged in the same layer on the lower surface side of the isolation layer 10.

  In the above description, the hydrogen gas generating agent 14 is coated with the hydrogen generating material 14a with the water-soluble coating 14b. However, as a modification of the present invention, the hydrogen gas generating agent 14 is not provided without providing the water-soluble coating 14b. May be configured. Specifically, a metal complex 14m in which a hydrogen generating substance 14a and an acid substance 14c are coordinated and bonded is granulated to a predetermined particle diameter, and hydrogen gas is used as particles in which at least a part of the hydrogen generating substance 14a is exposed on the surface. The generator 14 may be created. In the case of such a modification, since the sheet-like pack material 100 absorbs water and the hydrogen gas generating agent 14 comes into contact with water and the hydrogen generating substance 14a comes into contact with the water, hydrogen gas is generated compared to the above-described embodiment. Time is shortened. However, when sodium hydrogen carbonate is used as the carbon dioxide generating agent 12 and metal magnesium is used as the hydrogen generating material 14a, the reactivity with water is higher in the carbon dioxide generating agent 12 (sodium bicarbonate) than in the hydrogen generating material 14a ( Therefore, even when the water-soluble coating 14b is not provided on the hydrogen generating substance 14a as in the modification, the hydrogen gas generation time can be made longer than the carbon dioxide generation time. In other words, the hydrogen gas generation time is made longer than the carbon gas generation time by making the metal element constituting the carbon dioxide gas generating agent 12 more ionizing than the metal element constituting the hydrogen gas generating agent 14. It is possible.

The above embodiment includes the following technical idea.
