Description

蓄熱部材およびその製造方法、並びにそれを用いた保管容器、冷蔵庫、包装容器、服、グラスおよび枕Heat storage member and manufacturing method thereof, and storage container, refrigerator, packaging container, clothes, glass and pillow using the same
　本発明は、保温用に用いられる蓄熱部材およびその製造方法に関する。 The present invention relates to a heat storage member used for heat insulation and a manufacturing method thereof.
　従来、蓄熱部材は食品保存技術や医療技術等の様々な分野で用いられている。これらの蓄熱部材は例えば凝固点における潜熱を利用して保冷効果を生じる。蓄熱部材としては、プラスチックやゴム製の袋あるいは容器の内部に吸水性樹脂の含水ゲル組成物を密封したものが知られている。これらの既存の蓄熱部材は、鋳型を用いて吸水性樹脂粉末を膨潤させて含水ゲル組成物（蓄熱材）を成形し、型から取り出した成形体を袋や容器等の包装材内に挿入して密封するという製造工程を経る。 Conventionally, heat storage members are used in various fields such as food preservation technology and medical technology. These heat storage members produce a cold insulation effect using, for example, latent heat at the freezing point. As a heat storage member, a plastic or rubber bag or container in which a water-containing resin hydrogel composition is sealed is known. These existing heat storage members use a mold to swell the water-absorbent resin powder to form a hydrous gel composition (heat storage material), and insert the molded body taken out of the mold into a packaging material such as a bag or a container. It goes through the manufacturing process of sealing.
　特許文献１には、吸水性樹脂が分子状態で連続する均一なマトリックス層を形成し、該吸水性樹脂に吸収された水が該樹脂と化学的及び／又は物理的に結合して均質に分散されてなる吸水性樹脂の成形体に、少なくとも一種の凝固点降下作用のある水溶性化合物及び／又は少なくとも一種の０℃以下に凝固点を有する親水性有機溶剤を含有させてなる保冷剤用含水ゲル組成物が開示されている。 In Patent Document 1, a water-absorbent resin forms a uniform matrix layer that is continuous in a molecular state, and water absorbed in the water-absorbent resin is chemically and / or physically combined with the resin to be uniformly dispersed. A water-containing gel composition for a cold-retaining agent, wherein the molded article of the water-absorbent resin contains at least one water-soluble compound having a freezing point depressing action and / or at least one hydrophilic organic solvent having a freezing point at 0 ° C. or lower. Things are disclosed.
　特許文献２には、可動ベルト上で、アクリル系単量体溶液層の上面および下面を水で冷却しながら、溶液層上に設置した第一光照射手段による光照射を行なって、アクリル系単量体を連続的に光重合させる第一重合工程、および第一重合工程により得られる重合体をドラムを介して光照射手段上部に移行し、前記重合体に第一光照射手段による光照射を行なって、前記重合体をさらに光重合させる第二重合工程からなるアクリル系重合体の製造方法が開示されている。 In Patent Document 2, the acrylic monomer solution layer is irradiated with light by the first light irradiation means placed on the solution layer while cooling the upper and lower surfaces of the acrylic monomer solution layer with water on the movable belt. A first polymerization step for continuously photopolymerizing the polymer, and a polymer obtained by the first polymerization step is transferred to the upper portion of the light irradiation means via the drum, and the polymer is irradiated with light by the first light irradiation means. A method for producing an acrylic polymer comprising a second polymerization step of further photopolymerizing the polymer is disclosed.

　しかしながら、特許文献１の技術では、鋳型を用いて蓄熱材を成形した後、成形体を袋や容器等の包装材内に移すのに手間がかかるとともに、成形体を包装材内に移す際に型崩れが生じてしまうおそれがあるという問題がある。また、製造途中でゲル化していない蓄熱材が漏れて無駄になってしまい製造コストの低減が図れないという問題がある。また、従来の製造方法では、ゲル化剤により蓄熱材をゲル化（重合）させる際に、材料が大気中に触れる時間が長いため、酸素によるゲル化剤の重合阻害が起こり易いという問題もある。さらに、成形体を包装材に入れる際に脱気や脱泡を十分にし難いという問題もある。 However, in the technique of Patent Document 1, it takes time to move the molded body into a packaging material such as a bag or a container after the heat storage material is molded using a mold, and when the molded body is moved into the packaging material. There is a problem in that there is a risk of losing shape. In addition, there is a problem in that the heat storage material that is not gelled in the course of manufacturing leaks and is wasted, and the manufacturing cost cannot be reduced. Further, in the conventional production method, when the heat storage material is gelled (polymerized) with the gelling agent, there is also a problem that the polymerization of the gelling agent is likely to be inhibited by oxygen because the material is in contact with the air for a long time. . Furthermore, there is also a problem that it is difficult to sufficiently deaerate and defoam when the molded body is put into the packaging material.
　また、特許文献２に開示された可動式ベルト上でのアクリル系材料の光重合法によるフィルム材料の製造方法では、材料が大気中に暴露されてしまうため、酸素によるゲル化剤の重合阻害で分子量が大きくならず高分子材料が硬化し難いという問題が生じ得る。 Moreover, in the manufacturing method of the film material by the photopolymerization method of the acrylic material on the movable belt disclosed in Patent Document 2, since the material is exposed to the atmosphere, the polymerization of the gelling agent by oxygen is inhibited. There may be a problem that the molecular weight is not increased and the polymer material is difficult to cure.
　本発明の目的は、低コストで容易に製造できる蓄熱部材およびその製造方法を提供することにある。 An object of the present invention is to provide a heat storage member that can be easily manufactured at low cost and a method for manufacturing the same.

　本発明の一実施の形態による蓄熱部材およびその製造方法について、図１～図１６を用いて説明する。なお、以下の全ての図面においては、理解を容易にするため、各構成要素の寸法や比率などは適宜異ならせて図示している。 A heat storage member and a manufacturing method thereof according to an embodiment of the present invention will be described with reference to FIGS. In all the following drawings, the dimensions and ratios of the respective constituent elements are appropriately varied for easy understanding.
　図１は本実施形態における蓄熱部材の製造方法の概略を示している。まず、蓄熱材溶液を用意する。蓄熱材溶液としては例えば、冷却用蓄熱材である塩化カリウムと塩化アンモニウムを窒素ガスで脱酸素処理をした水に溶解させた水溶液を用いることができる。さらに、ゲル化剤および、重合開始剤、架橋剤（以下、これらを総称して「ゲル化材料」と表記する場合がある）を用意する。重合開始剤はゲル化剤を光重合により重合させる場合は光重合開始剤を用い、熱重合により重合させる場合は熱重合開始剤を用いる。また、光および熱による重合をさせる場合には光重合開始剤および熱重合開始剤を用いる。 FIG. 1 shows an outline of a method for manufacturing a heat storage member in the present embodiment. First, a heat storage material solution is prepared. As the heat storage material solution, for example, an aqueous solution in which potassium chloride and ammonium chloride, which are heat storage materials for cooling, are dissolved in water deoxygenated with nitrogen gas can be used. Furthermore, a gelling agent, a polymerization initiator, and a crosslinking agent (hereinafter, these may be collectively referred to as “gelling material”) are prepared. As the polymerization initiator, a photopolymerization initiator is used when the gelling agent is polymerized by photopolymerization, and a thermal polymerization initiator is used when polymerization is performed by thermal polymerization. In the case of polymerization by light and heat, a photopolymerization initiator and a thermal polymerization initiator are used.
　また、蓄熱材溶液とゲル化材料を収容する空間が形成可能な包装材を用意する。包装材は、蓄熱材溶液とゲル化材料を投入可能な投入口が開口されている。また、包装材は、ＵＶ（紫外）光を透過する素材及び／又は熱伝導性に優れた素材で形成されている。また、包装材は、蓄熱材溶液とゲル化材料を密封した状態で外部から圧力を加えると容易に変形可能な素材で形成されている。 Also, a packaging material capable of forming a space for storing the heat storage material solution and the gelling material is prepared. The packaging material has an opening through which a heat storage material solution and a gelling material can be introduced. Further, the packaging material is formed of a material that transmits UV (ultraviolet) light and / or a material that is excellent in thermal conductivity. The packaging material is formed of a material that can be easily deformed when pressure is applied from the outside in a state where the heat storage material solution and the gelling material are sealed.
　第１ステップＳ１では、包装材に開口された投入口から蓄熱材溶液とゲル化材料を投入する。なお、蓄熱材溶液に代えて、塩化カリウムと塩化アンモニウムと水をゲル化剤とともに包装材に投入してもよい。次いで、第２ステップＳ２において、蓄熱材溶液とゲル化材料が充填された包装材の空間内の脱気、脱泡をして投入口を封止（シール）する。次いで、第３ステップＳ３において、包装材に対し外部から圧力を加えて包装材の形状を変化させる動作を繰り返して、包装材内で蓄熱材溶液にゲル化材料を混合して溶解させる。次いで、第４ステップＳ４において、包装材外部からＵＶ光照射及び／又は加熱することにより、ゲル化させた蓄熱材を包装材で内包した蓄熱部材が完成する。 In the first step S1, the heat storage material solution and the gelling material are charged from the charging port opened in the packaging material. In place of the heat storage material solution, potassium chloride, ammonium chloride, and water may be added to the packaging material together with the gelling agent. Next, in the second step S2, the inlet is sealed (sealed) by degassing and degassing the space of the packaging material filled with the heat storage material solution and the gelling material. Next, in the third step S3, the operation of changing the shape of the packaging material by applying external pressure to the packaging material is repeated, and the gelling material is mixed and dissolved in the heat storage material solution in the packaging material. Next, in a fourth step S4, UV light irradiation and / or heating is performed from the outside of the packaging material, thereby completing a heat storage member in which the gelled heat storage material is included in the packaging material.
　図２は比較例としての従来の蓄熱部材の製造方法の概略を示している。まず、第１ステップＳ１０１において、所定の容器内で蓄熱材とゲル化材料を水に混合して溶解させる。次いで、第２ステップＳ１０２において、ゲル化材料を溶解させた蓄熱材溶液を型に流し込み、ＵＶ光照射及び／又は加熱することによりゲル化させた蓄熱材を成型する。次いで、第３ステップＳ１０３において、包装材に開口された挿入口からゲル化した蓄熱材を挿入する。次いで、第４ステップＳ１０４において、蓄熱材が充填された包装材の空間内の脱気、脱泡をして挿入口を封止（シール）して蓄熱部材が完成する。 FIG. 2 shows an outline of a conventional method for manufacturing a heat storage member as a comparative example. First, in the first step S101, the heat storage material and the gelling material are mixed and dissolved in water in a predetermined container. Next, in the second step S102, the heat storage material solution in which the gelling material is dissolved is poured into a mold, and the heat storage material that has been gelated by UV light irradiation and / or heating is molded. Next, in the third step S103, the gelled heat storage material is inserted from the insertion opening opened in the packaging material. Next, in a fourth step S104, the heat storage member is completed by degassing and degassing the space of the packaging material filled with the heat storage material and sealing (sealing) the insertion port.
　図２に示す比較例による蓄熱部材の製造方法の第２ステップＳ１０２でのゲル化工程では、蓄熱材とゲル化材料が溶解した水溶液を型に流し込むため、当該水溶液が大気中に暴露されてしまうので、大気中の酸素によるゲル化剤の重合阻害が生じてしまうという課題がある。これに対し、図１に示す本実施形態の蓄熱部材の製造方法では、第４ステップＳ４でのゲル化工程より前の第２ステップＳ２において、蓄熱材溶液とゲル化材料が充填された包装材の空間内の脱気、脱泡をして投入口を封止している。このため、完全密封した包装材内で蓄熱材がゲル化されるため、蓄熱材溶液とゲル化材料が大気中に暴露しないので酸素による重合阻害は生じない。 In the gelation process in the second step S102 of the method for manufacturing the heat storage member according to the comparative example shown in FIG. 2, since the aqueous solution in which the heat storage material and the gelling material are dissolved is poured into the mold, the aqueous solution is exposed to the atmosphere. Therefore, there is a problem that polymerization of the gelling agent is inhibited by oxygen in the atmosphere. On the other hand, in the manufacturing method of the heat storage member of this embodiment shown in FIG. 1, the packaging material filled with the heat storage material solution and the gelling material in the second step S2 before the gelation step in the fourth step S4. The inlet is sealed by deaeration and defoaming in the space. For this reason, since a heat storage material is gelatinized within the completely sealed packaging material, since the heat storage material solution and the gelled material are not exposed to the atmosphere, polymerization inhibition by oxygen does not occur.
　また、図２に示す比較例による蓄熱部材の製造方法の第３ステップＳ１０３におけるゲル化した蓄熱材を包装材に挿入する挿入工程では、蓄熱材がゲル状なので包装材に挿入する際に手間がかかるだけでなく、挿入する際の力の作用により蓄熱材が漏れ出てしまったり、蓄熱材が型崩れしたりするおそれがある。これに対し、図１に示す本実施形態の蓄熱材の製造方法の第１ステップＳ１では、包装材の投入口から投入する蓄熱材溶液は液状なので投入し易いだけでなく、投入する際に蓄熱材溶液の漏洩防止が容易であり、蓄熱材の型崩れの心配もない。 Moreover, in the insertion process which inserts the gelatinized heat storage material in 3rd step S103 of the manufacturing method of the heat storage member by the comparative example shown in FIG. 2 in a packaging material, since heat storage material is a gel form, it takes time and effort when inserting in a packaging material. In addition to this, there is a risk that the heat storage material leaks out due to the action of the force at the time of insertion, or the heat storage material loses its shape. On the other hand, in the first step S1 of the manufacturing method of the heat storage material of the present embodiment shown in FIG. 1, the heat storage material solution input from the input port of the packaging material is not only easy to input because it is liquid, but also stores heat when input. It is easy to prevent leakage of the material solution, and there is no fear of the shape of the heat storage material.
　また、図２に示す比較例による蓄熱部材の製造方法では、第４ステップＳ１０４での封止工程より前の第２ステップＳ１０２のゲル化工程で蓄熱材がゲル化されているため、第４ステップＳ１０４の封止工程では、ゲル化した蓄熱材が邪魔になり、封止する際に脱気や脱泡処理が困難になる。これに対し、図１に示す本実施形態の蓄熱材の製造方法の第２ステップＳ２の封止工程では、包装材の空間内は液状なので、投入口を封止する際の包装材の空間内の脱気や脱泡を容易に行うことができる。 Moreover, in the manufacturing method of the heat storage member by the comparative example shown in FIG. 2, since the heat storage material is gelatinized by the gelation process of 2nd step S102 before the sealing process in 4th step S104, it is 4th step. In the sealing step of S104, the gelled heat storage material becomes an obstacle, and degassing and defoaming processing becomes difficult when sealing. On the other hand, in the sealing step of the second step S2 of the method for manufacturing the heat storage material of the present embodiment shown in FIG. 1, the space in the packaging material is liquid, and therefore the space in the packaging material when the inlet is sealed. Can be easily degassed and defoamed.
　また、図２に示す比較例による蓄熱部材の製造方法では、第１ステップＳ１０１において、蓄熱材とゲル化材料を水に混合して溶解させるためにある程度大きな容積を有する容器（タンク）を用意する必要が生じる。これに対し、図１に示す本実施形態による蓄熱部材の製造方法では、第３ステップＳ３において、包装材に対し外部から圧力を加えて包装材の形状を変化させる動作を繰り返すだけで、包装材内で蓄熱材溶液にゲル化材料を容易に混合して溶解させることができるので、混合溶解工程のコストを低減させることができる。 Moreover, in the manufacturing method of the heat storage member by the comparative example shown in FIG. 2, in 1st step S101, the container (tank) which has a certain large volume is prepared in order to mix and dissolve a heat storage material and a gel material. Need arises. On the other hand, in the manufacturing method of the heat storage member according to the present embodiment shown in FIG. 1, in the third step S3, simply by repeating the operation of changing the shape of the packaging material by applying pressure to the packaging material from the outside. Since the gelling material can be easily mixed and dissolved in the heat storage material solution, the cost of the mixing and dissolving step can be reduced.
　また、図２に示す比較例による蓄熱部材の製造方法では、第３ステップＳ１０３において、ゲル化した蓄熱材を包装材の挿入口から包装材内部に挿入する。このため、ゲル化した蓄熱材を隙間なく包装材の空間部に充填させるには、包装材の空間形状の自由度が制限されてしまう。これに対し、図１に示す本実施形態による蓄熱部材の製造方法では、第１ステップＳ１で包装材に開口された投入口から蓄熱材溶液とゲル化材料を投入して、第２ステップＳ２で投入口を封止している。液体は収容容器の内部空間の形状に倣うので、本実施形態の包装材の空間形状は蓄熱材料等で自由度が制限されない。このため、本実施形態による製造方法で製造される蓄熱部材の包装材の空間形状は任意の形状を採用できる。換言すると、本実施形態によれば、包装材の立体形状に倣ったゲル化した蓄熱材を製造することができる。 In the heat storage member manufacturing method according to the comparative example shown in FIG. 2, the gelled heat storage material is inserted into the packaging material from the insertion port of the packaging material in the third step S103. For this reason, in order to fill the gelled heat storage material into the space of the packaging material without any gap, the degree of freedom of the space shape of the packaging material is limited. On the other hand, in the manufacturing method of the heat storage member according to the present embodiment shown in FIG. 1, the heat storage material solution and the gelling material are input from the input port opened in the packaging material in the first step S1, and in the second step S2. The inlet is sealed. Since the liquid follows the shape of the internal space of the storage container, the degree of freedom of the space shape of the packaging material of the present embodiment is not limited by a heat storage material or the like. For this reason, the space shape of the packaging material of the heat storage member manufactured by the manufacturing method according to the present embodiment can adopt an arbitrary shape. In other words, according to the present embodiment, a gelled heat storage material that follows the three-dimensional shape of the packaging material can be manufactured.
　次に、本実施形態で用いる蓄熱材の組成について説明する。無機蓄熱材料として無機塩水溶液又は無機塩水和物が用いられる。無機塩水溶液には、例えば、塩化カリウム（ＫＣｌ）と塩化アンモニウム（ＮＨ４Ｃｌ）とを水に溶解した水溶液や、塩化ナトリウム（ＮａＣｌ）と塩化アンモニウム（ＮＨ４Ｃｌ）とを水に溶解した水溶液が用いられる。また、蓄熱材の無機蓄熱材料に無機塩水溶液を用いる場合には、過冷却防止剤としてリン酸水素二ナトリウム（無水）（Ｎａ２ＨＰＯ４）やホウ砂（四ホウ酸ナトリウム十水和物（Ｎａ２Ｂ４Ｏ７・１０Ｈ２Ｏ））、ホウ砂（四ホウ酸ナトリウム五水和物（Ｎａ２Ｂ４Ｏ７・５Ｈ２Ｏ））が用いられる。相分離防止剤として、カルボキシメチルセルロース（ＣＭＣ）などを添加してもよい。無機塩水和物には、例えば、硫酸ナトリウム十水和物（Ｎａ２ＳＯ４・１０Ｈ２Ｏ）、酢酸ナトリウム三水和物、チオ硫酸ナトリウム五水和物、リン酸水素二ナトリウム十二水和物とリン酸水素二カリウム六水和物との二元系組成物（融解点５℃）、硝酸リチウム三水和物を主成分とする硝酸リチウム三水和物と塩化マグネシウム六水和物との二元系組成物（融解点８～１２℃）や、硝酸リチウム三水和物－塩化マグネシウム六水和物－臭化マグネシウム六水和物の三元系組成物（融解点５．８～９．７℃）が用いられ、過冷却防止剤としてリン酸水素二ナトリウム（無水）（Ｎａ２ＨＰＯ４）やホウ砂（四ホウ酸ナトリウム十水和物（Ｎａ２Ｂ４Ｏ７・１０Ｈ２Ｏ））、ホウ砂（四ホウ酸ナトリウム五水和物（Ｎａ２Ｂ４Ｏ７・５Ｈ２Ｏ））を添加してもよい。 Next, the composition of the heat storage material used in the present embodiment will be described.

＜蓄熱材溶液＞

　次いで、図４（ｃ）に示すように、包装材１の外部から空間部１ｂ内の溶液３に向けて、常温（例えば、２０℃）でＵＶ光（波長３６５ｎｍ）を２時間照射する。これにより、図４（ｄ）に示すように、ダブルネットワーク構造７、９が形成されてゲル化した蓄熱材５を包装材１で包装した蓄熱部材が完成する。本実施例による蓄熱部材では、潜熱量２４５．９８Ｊ／ｇの蓄熱性能が得られた。 Next, as shown in FIG. 4 (c), UV light (wavelength 365 nm) is irradiated for 2 hours from the outside of the packaging material 1 toward the solution 3 in the space 1b at room temperature (for example, 20 ° C.). Thereby, as shown in FIG.4 (d), the thermal storage member which wrapped the thermal storage material 5 by which the double network structures 7 and 9 were formed and gelatinized with the packaging material 1 is completed. With the heat storage member according to this example, a heat storage performance of a latent heat amount of 245.98 J / g was obtained.
　このように上記実施例では、２種類のゲル化剤を用いているが１種類以上の相互貫入構造を形成させる有機材料をゲル化剤に用いることができる。上記実施例によれば、ゲル化工程において型は使用する必要がなく、ＵＶ光に対して透明な包装材中に直接、蓄熱材溶液とゲル化材料を投入して混合するので、製造工程の簡略化が図れるとともに材料の漏れや、ゲル化した蓄熱材の型崩れを防止できる。また、ゲル化剤の重合阻害等を防ぐことができる。 Thus, although two types of gelling agents are used in the above embodiment, an organic material that forms one or more interpenetrating structures can be used as the gelling agent. According to the above embodiment, the mold does not need to be used in the gelation process, and the heat storage material solution and the gel material are directly mixed and mixed in the packaging material transparent to UV light. In addition to simplification, it is possible to prevent material leakage and loss of shape of the gelled heat storage material. In addition, polymerization inhibition of the gelling agent can be prevented.
　本実施形態による蓄熱部材の製造方法は、包装材に蓄熱ゲル化材料を合成する材料を一度に投入し、包装材を押圧等して材料を溶解させる。従来は、材料を合成させる際、タンク等の容器を用い、ゲル化させてから包装材に入れるが、本実施形態による蓄熱部材の製造方法では、材料を直接包装材に投入することによって製造工程を減少させることができる。 In the method for manufacturing a heat storage member according to the present embodiment, a material for synthesizing a heat storage gel material is put into a packaging material at a time, and the material is dissolved by pressing the packaging material. Conventionally, when a material is synthesized, a container such as a tank is used, and after gelation, the material is put into a packaging material. However, in the method for producing a heat storage member according to the present embodiment, the production process is performed by directly introducing the material into the packaging material. Can be reduced.
　従来のタンク等の容器でゲル化の合成を行い、生成物を包装材で包む場合、ゲル化した材料の漏れや手間がかかることや真空にし難い、型崩れを起こすという課題があったが本実施形態による蓄熱部材の製造方法を用いることによって、液状のままパック詰めを行うため、材料を投入し易く、脱気もし易くなり、これらの課題を解決することができる。 In the case of synthesizing gelation in a conventional container such as a tank and wrapping the product with packaging material, there are problems that the gelled material leaks, takes time, is difficult to vacuum, and loses its shape. By using the manufacturing method of the heat storage member according to the embodiment, the packing is performed in a liquid state, so that the material can be easily input and the deaeration can be easily performed, and these problems can be solved.
　従来の鋳型の容器でゲル化させる際にＵＶ光を照射し光重合させたり、熱重合させたり、加熱・冷却によってゲル化させたりするが、本実施形態による蓄熱部材の製造方法ではＵＶ光を透過させる透明な包装材を用い、包装材を挟みこんで光照射を行う照射装置、又は片側から光照射を行い、反対側に反射材を配置するような装置を用いることによって、常に包装材の両側から光照射を行うことができ、短時間で効率的に光照射を行え、コストの削減にも寄与することができる。特許文献２に記載されているような、従来の可動式ベルト上でのアクリル系材料の光重合法によるフィルム材料の製造方法では材料が大気中に暴露されてしまうため、酸素によるゲル化剤の重合阻害で分子量が大きくならず高分子材料が硬化し難いという問題がある。これに対し、本実施形態による蓄熱部材の製造方法を用い、脱酸素した材料を包装材に投入し、封止することによって材料が大気中に暴露され、ゲル化剤の重合阻害が起こることは無くなり、硬化させることができる。 When gelling in a conventional mold container, UV light is irradiated for photopolymerization, thermal polymerization, or gelation by heating / cooling. In the heat storage member manufacturing method according to the present embodiment, UV light is irradiated. By using a transparent packaging material that allows transmission and irradiating light by sandwiching the packaging material, or by using a device that irradiates light from one side and places a reflective material on the opposite side, Light irradiation can be performed from both sides, light irradiation can be performed efficiently in a short time, and it can contribute to cost reduction. In the conventional method for producing a film material by photopolymerization of an acrylic material on a movable belt as described in Patent Document 2, the material is exposed to the atmosphere. There is a problem in that the molecular weight does not increase due to polymerization inhibition and the polymer material is difficult to cure. On the other hand, by using the method for manufacturing a heat storage member according to the present embodiment, the deoxygenated material is put into a packaging material and sealed, so that the material is exposed to the atmosphere and polymerization of the gelling agent is inhibited. It can be lost and cured.
　次に、図６～図１６を用いて本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の具体的構成例について説明する。図６は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その１）を示している。図６に示す蓄熱部材１０は、例えば、冷蔵庫の壁部や庫内の棚部材に配置したり、クーラーボックスの壁部に配置したりするのに好適な形状を有している。図６（ａ）は蓄熱部材１０の平面図であり、図６（ｂ）は図６（ａ）のＢ－Ｂ線で切断した蓄熱部材１０の断面を示している。図６に示すように蓄熱部材１０は平面形状が長方形の薄い袋状をしている。蓄熱部材１０の長方形平面部の周辺部を封止した袋状の包装材１２の空間部内に蓄熱材５が収容されている。包装材１２の長方形平面部の周辺部の四辺のうちの一辺には、蓄熱材溶液とゲル化材料を投入した投入口を封止した封止部１６が形成されている。封止部１６の幅の長さは、包装材１２内の蓄熱材５の封止部１６と同方向に測った長さより短い。また、本例では蓄熱部材１０の周辺部より中央部の方が蓄熱材５の厚さが厚くなっている。 Next, a specific configuration example of the heat storage member manufactured by the method of manufacturing the heat storage member according to the present embodiment will be described with reference to FIGS. FIG. 6 shows a configuration example (No. 1) of the heat storage member manufactured by the method for manufacturing the heat storage member according to the present embodiment. The heat storage member 10 shown in FIG. 6 has a shape suitable for, for example, arranging on a wall portion of a refrigerator or a shelf member in a refrigerator, or on a wall portion of a cooler box. 6A is a plan view of the heat storage member 10, and FIG. 6B shows a cross section of the heat storage member 10 cut along line BB in FIG. 6A. As shown in FIG. 6, the heat storage member 10 has a thin bag shape with a rectangular planar shape. The heat storage material 5 is accommodated in the space part of the bag-shaped packaging material 12 which sealed the peripheral part of the rectangular plane part of the heat storage member 10. On one side of the four sides of the peripheral portion of the rectangular flat portion of the packaging material 12, a sealing portion 16 is formed that seals the inlet into which the heat storage material solution and the gelling material are charged. The width of the sealing part 16 is shorter than the length measured in the same direction as the sealing part 16 of the heat storage material 5 in the packaging material 12. Moreover, in this example, the thickness of the heat storage material 5 is thicker in the central portion than in the peripheral portion of the heat storage member 10.
　図７は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その２）を示している。図７に示す蓄熱部材２０は、例えば、冷蔵庫の壁部や庫内の棚部材に配置したり、クーラーボックスの壁部に配置したりするのに好適な形状を有している。図７（ａ）は蓄熱部材２０の平面図であり、図７（ｂ）は図７（ａ）のＣ－Ｃ線で切断した蓄熱部材２０の断面を示している。図７に示すように蓄熱部材２０は平面形状が長方形の薄い直方体形状をしている。蓄熱部材２０の長方形平面部の周辺部を封止した袋状の包装材２２の空間部内に蓄熱材５が収容されている。包装材２２の長方形平面部の周辺部の四辺のうちの一辺には、蓄熱材溶液とゲル化材料を投入した投入口を封止した封止部２６が形成されている。封止部２６の長さは、包装材２２内の蓄熱材５の封止部２６と同方向に測った長さより短い。包装材２２の長方形平面には例えば３行３列のマトリクス状に例えば円形状の穴部２４が９個開口されている。穴部２４周囲は封止されている。包装材２２の空間部は平面方向に見てマトリクス状に配置された穴部２４を除く格子状に画定されている。複数の穴部２４は包装材２２の空間部の厚さを規定する厚さ規定部材として機能する。このため、図７に示す蓄熱部材２０は、図６に示す蓄熱部材１０に比して周辺部と中央部の厚さの差を小さくできるので、蓄熱部材２０の長方形表面をより厚さが均一な平坦にすることができる。蓄熱部材２０の方が冷蔵庫の壁部や庫内の棚部材、あるいはクーラーボックスの壁部に高い密着性で容易に配置できる。 FIG. 7 shows a configuration example (No. 2) of the heat storage member manufactured by the method of manufacturing the heat storage member according to the present embodiment. The heat storage member 20 shown in FIG. 7 has a shape suitable for, for example, arranging on a wall part of a refrigerator or a shelf member in a warehouse, or on a wall part of a cooler box. FIG. 7A is a plan view of the heat storage member 20, and FIG. 7B shows a cross section of the heat storage member 20 cut along line CC in FIG. 7A. As shown in FIG. 7, the heat storage member 20 has a thin rectangular parallelepiped shape with a rectangular planar shape. The heat storage material 5 is accommodated in the space part of the bag-shaped packaging material 22 which sealed the peripheral part of the rectangular plane part of the heat storage member 20. On one side of the four sides of the peripheral portion of the rectangular flat portion of the packaging material 22, a sealing portion 26 is formed that seals the inlet into which the heat storage material solution and the gelling material are charged. The length of the sealing part 26 is shorter than the length measured in the same direction as the sealing part 26 of the heat storage material 5 in the packaging material 22. On the rectangular plane of the packaging material 22, for example, nine circular holes 24 are opened in a matrix of 3 rows and 3 columns, for example. The periphery of the hole 24 is sealed. The space portion of the packaging material 22 is defined in a lattice shape excluding the hole portions 24 arranged in a matrix when viewed in the plane direction. The plurality of holes 24 function as a thickness defining member that defines the thickness of the space portion of the packaging material 22. For this reason, since the heat storage member 20 shown in FIG. 7 can make the difference of the thickness of a peripheral part and a center part small compared with the heat storage member 10 shown in FIG. 6, the thickness of the rectangular surface of the heat storage member 20 is more uniform. Can be flat. The heat storage member 20 can be easily arranged with high adhesion on the wall portion of the refrigerator, the shelf member in the refrigerator, or the wall portion of the cooler box.
　蓄熱部材２０の包装材２２の空間内にすでにゲル化した蓄熱材を封止部２４を介して封入することは困難である。これに対し本実施の形態による蓄熱部材の製造方法によれば、包装材２２の空間部に蓄熱材溶液とゲル化材料を封入してからゲル化させた蓄熱材５を形成するので、包装材２２の空間部が複雑な空間形状を有していても当該空間形状に倣う蓄熱材５を極めて容易に形成できる。 It is difficult to encapsulate the heat storage material already gelled in the space of the packaging material 22 of the heat storage member 20 through the sealing portion 24. On the other hand, according to the manufacturing method of the heat storage member according to the present embodiment, the heat storage material 5 and the gelled material are sealed in the space portion of the packaging material 22 and then the gelled heat storage material 5 is formed. Even if the space portion 22 has a complicated space shape, the heat storage material 5 following the space shape can be formed very easily.
　図８は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その３）を示している。図８に示す蓄熱部材３０は、例えば、冷蔵庫の壁部や庫内の棚部材に配置したり、クーラーボックスの壁部に配置したりするのに好適な形状を有している。図８（ａ）は蓄熱部材３０の平面図であり、図８（ｂ）は図８（ａ）のＤ－Ｄ線で切断した蓄熱部材３０の断面および蓄熱部材３０を冷蔵庫の棚部材２００に取り付けた状態を示している。図８に示すように蓄熱部材３０は平面形状が長方形の薄い直方体形状をしている。蓄熱部材３０の長方形平面部の周辺部を封止した袋状の包装材３２の空間部内に蓄熱材５が収容されている。包装材３２の長方形平面部の周辺部の四辺のうちの一辺には、蓄熱材溶液とゲル化材料を投入した投入口を封止した封止部３６が形成されている。封止部３６の長さは、包装材３２内の蓄熱材５の封止部３６と同方向に測った長さより短い。包装材３２の長方形平面の四隅近傍には２行２列のマトリクス状に例えば円形状の穴部３４が開口されている。穴部３４周囲は封止されている。穴部３４は蓄熱部材３０を冷蔵庫の棚部材２００の裏面に取り付ける際に取付部材２０２を貫通させる貫通穴として機能する。取付部材２０２は例えば、穴部３４の内径より広い外径を有するねじ頭と、ねじ頭から延びて穴部３４より狭い径でおねじが切られた軸とを有するねじ部材である。４か所の穴部３４について、取付部材２０２の軸を蓄熱部材３０の穴部３４に貫通させて棚部材２００の所定位置に設けられためねじ部（不図示）と螺合させることにより、棚部材２００に蓄熱部材３０を保持することができる。このため、図８に示す蓄熱部材３０は、冷蔵庫の壁部や庫内の棚部材、あるいはクーラーボックスの壁部に容易に配置できる。 FIG. 8 shows a configuration example (No. 3) of the heat storage member manufactured by the method of manufacturing the heat storage member according to the present embodiment. The heat storage member 30 shown in FIG. 8 has a shape suitable for, for example, arranging on a wall portion of a refrigerator or a shelf member in a refrigerator, or on a wall portion of a cooler box. 8 (a) is a plan view of the heat storage member 30, and FIG. 8 (b) is a cross-sectional view of the heat storage member 30 cut along the line DD in FIG. 8 (a) and the heat storage member 30 to the shelf member 200 of the refrigerator. The attached state is shown. As shown in FIG. 8, the heat storage member 30 has a thin rectangular parallelepiped shape with a rectangular planar shape. The heat storage material 5 is accommodated in the space part of the bag-shaped packaging material 32 which sealed the peripheral part of the rectangular plane part of the heat storage member 30. On one side of the four sides of the peripheral portion of the rectangular flat portion of the packaging material 32, a sealing portion 36 is formed that seals the inlet into which the heat storage material solution and the gelling material are charged. The length of the sealing part 36 is shorter than the length measured in the same direction as the sealing part 36 of the heat storage material 5 in the packaging material 32. For example, circular holes 34 are opened in a matrix of 2 rows and 2 columns in the vicinity of the four corners of the rectangular plane of the packaging material 32. The periphery of the hole 34 is sealed. The hole 34 functions as a through hole that allows the attachment member 202 to penetrate when the heat storage member 30 is attached to the back surface of the shelf member 200 of the refrigerator. The mounting member 202 is, for example, a screw member having a screw head having an outer diameter wider than the inner diameter of the hole portion 34 and a shaft extending from the screw head and having a diameter narrower than that of the hole portion 34. With respect to the four hole portions 34, the shaft of the mounting member 202 penetrates the hole portion 34 of the heat storage member 30 and is provided at a predetermined position of the shelf member 200, so that it is screwed with a screw portion (not shown). The heat storage member 30 can be held on the member 200. For this reason, the heat storage member 30 shown in FIG. 8 can be easily disposed on the wall portion of the refrigerator, the shelf member in the refrigerator, or the wall portion of the cooler box.
　複数の穴部３４が形成された包装材３２の空間形状にすでにゲル化した蓄熱材を封入することは困難である。これに対し本実施の形態による蓄熱部材の製造方法によれば、包装材３２の空間部に蓄熱材溶液とゲル化材料を封入してからゲル化させた蓄熱材５を形成するので、包装材３２の空間部が複雑な空間形状を有していても当該空間形状に倣う蓄熱材５を極めて容易に形成できる。 It is difficult to enclose the heat storage material already gelled in the space shape of the packaging material 32 in which a plurality of holes 34 are formed. On the other hand, according to the manufacturing method of the heat storage member according to the present embodiment, the heat storage material 5 and the gelled material are sealed in the space of the packaging material 32 and then the gelled heat storage material 5 is formed. Even if the 32 space portions have a complicated space shape, the heat storage material 5 following the space shape can be formed very easily.
　図９は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その４）を示している。図９は蓄熱部材４０の断面および蓄熱部材４０を冷蔵庫の棚部材２００の下面側に取り付けた状態を示している。蓄熱部材４０は断面が楔状（テーパ状）の三角柱形状の包装材４２を有している。包装材４２の空間部内には蓄熱材５が収容されている。包装材４２の断面楔状の底面部には、蓄熱材溶液とゲル化材料を投入した投入口を封止した封止部４６が形成されている。封止部４６の長さは、包装材４２内の蓄熱材５の封止部４６と同方向に測った長さより短い。蓄熱部材４０は、棚部材２００に取り付けた状態で水平面に対し傾斜する傾斜平面４４を有している。このため、棚部材２００に取り付けた蓄熱部材４０の表面に結露が生じたとしても、露は傾斜平面４４上端から下端に向かう矢印ｃ方向に流れて傾斜平面４４の下端部に移動してから矢印ｄに示す鉛直下方に落下する。これにより、蓄熱部材４０の真下全体に一様に露が落下することを防ぐことができる。傾斜平面４４の断面形状は図９に示す楔型に限らず種々の形状をとることができる。傾斜下端を所望の位置に配置することにより露の落ちる位置を容易に制御できる。 FIG. 9 shows a configuration example (No. 4) of the heat storage member manufactured by the method for manufacturing the heat storage member according to the present embodiment. FIG. 9 shows a cross section of the heat storage member 40 and a state in which the heat storage member 40 is attached to the lower surface side of the shelf member 200 of the refrigerator. The heat storage member 40 has a triangular prism-shaped packaging material 42 having a wedge-shaped (tapered) cross section. The heat storage material 5 is accommodated in the space of the packaging material 42. On the bottom surface of the packaging material 42 having a wedge-shaped cross section, a sealing portion 46 is formed that seals the charging port into which the heat storage material solution and the gelling material are charged. The length of the sealing part 46 is shorter than the length measured in the same direction as the sealing part 46 of the heat storage material 5 in the packaging material 42. The heat storage member 40 has an inclined plane 44 that is inclined with respect to a horizontal plane when attached to the shelf member 200. For this reason, even if dew condensation occurs on the surface of the heat storage member 40 attached to the shelf member 200, the dew flows in the direction of the arrow c from the upper end of the inclined plane 44 to the lower end and moves to the lower end of the inclined plane 44 before the arrow. It falls down vertically as shown in d. Thereby, it is possible to prevent the dew from falling evenly under the entire heat storage member 40. The cross-sectional shape of the inclined plane 44 is not limited to the wedge shape shown in FIG. 9 and can take various shapes. The position where the dew drops can be easily controlled by arranging the inclined lower end at a desired position.
　また、従来の蓄熱材の製造方法では、包装材４２の楔状空間の上端の角部（図中の破線で示す楕円形ａで示す領域）や下端の角部（図中の破線で示す楕円形ｂで示す領域）にゲル化した蓄熱材を配置するのはほぼ不可能である。これに対し本実施の形態による蓄熱部材の製造方法によれば、包装材４２の空間部に蓄熱材溶液とゲル化材料を封入してからゲル化させた蓄熱材５を形成するので、包装材４２の空間部が複雑な空間形状を有していても当該空間形状に倣う蓄熱材５を極めて容易に確実に形成できる。 In addition, in the conventional method for manufacturing a heat storage material, the upper corner (the region indicated by the ellipse a indicated by the broken line in the figure) and the lower end (the ellipse indicated by the broken line in the figure) of the wedge-shaped space of the packaging material 42 are used. It is almost impossible to dispose the gelled heat storage material in the region (b). On the other hand, according to the manufacturing method of the heat storage member according to the present embodiment, since the heat storage material 5 and the gelled material are sealed in the space portion of the packaging material 42 and then the gelled heat storage material 5 is formed, the packaging material is used. Even if the space portion 42 has a complicated space shape, the heat storage material 5 following the space shape can be formed very easily and reliably.

FIG. 10A schematically shows a cross-section inside the refrigerator. The refrigerator door 202 is located on the left side of the refrigerator, and the wall 204 on the back side of the refrigerator is located on the right side of the figure. Show. The refrigerator shelf member 200 is horizontally disposed in the interior space between the refrigerator door 202 and the back wall portion 204. The heat storage member 50 is attached to the upper surface side of the shelf member 200 of the refrigerator. The packaging material 52 of the heat storage member 50 has a thin rectangular parallelepiped shape in plan view, and has a bent portion where one end side of the rectangular parallelepiped is bent substantially at a right angle. The heat storage material 5 is accommodated in a solid shape following the shape of the internal space in the internal space of the rectangular parallelepiped of the packaging material 52 and the subsequent bent portion. The L-shaped heat storage member 50 is placed on the top surface of the shelf member 200 so that the folded portion of the packaging material 52 faces downward and the folded portion is hooked on the rear end portion of the shelf member 200. When the heat storage member 50 is placed on the top surface of the shelf member 200, a bent portion is inserted between the back wall portion 204 and the back end portion of the shelf member 200, so that the heat storage member 50 is stably placed on the shelf member 200. Can be fixed. Of course, a concave portion may be formed in the back wall portion 204, and a bent portion may be inserted into the concave portion to be hooked.
　蓄熱部材５０の包装材５２の空間形状にすでにゲル化した蓄熱材を封入することは困難である。これに対し本実施の形態による蓄熱部材の製造方法によれば、包装材５２の空間部に蓄熱材溶液とゲル化材料を封入してからゲル化させた蓄熱材５を形成するので、包装材５２の空間部が複雑な空間形状を有していても当該空間形状に倣う蓄熱材５を極めて容易に形成できる。 It is difficult to enclose the heat storage material already gelled in the space shape of the packaging material 52 of the heat storage member 50.

　図１０（ｂ）は、冷蔵庫の棚部材２００の上面を模式的に示している。Ｌ字形状の蓄熱部材５５が棚部材２００の上面側に２個取り付けられている。蓄熱部材５５の包装材５７は、平面形状がＬ字形状の薄い袋状をしている。包装材５７の内部空間には当該内部空間の形状に倣う立体形状で蓄熱材５が収容されている。２つの蓄熱部材５５の一方は表面を棚部材２００の上面に対向して配置され、他方は裏面を棚部材２００の上面に対向して配置されている。２つの蓄熱部材５５は、線対称に配置されて棚部材２００の長方形平面の三辺に沿って配置されている。 FIG. 10B schematically shows the top surface of the shelf member 200 of the refrigerator. Two L-shaped heat storage members 55 are attached to the upper surface side of the shelf member 200. The packaging material 57 of the heat storage member 55 has a thin bag shape with an L-shaped planar shape. The heat storage material 5 is accommodated in the internal space of the packaging material 57 in a three-dimensional shape following the shape of the internal space. One of the two heat storage members 55 is disposed with the front surface facing the top surface of the shelf member 200, and the other is disposed with the back surface facing the top surface of the shelf member 200. The two heat storage members 55 are arranged in line symmetry and are arranged along three sides of the rectangular plane of the shelf member 200.
　蓄熱部材５５の包装材５７の空間形状にすでにゲル化した蓄熱材を封入することは困難である。これに対し本実施の形態による蓄熱部材の製造方法によれば、包装材５７の空間部に蓄熱材溶液とゲル化材料を封入してからゲル化させた蓄熱材５を形成するので、包装材５７の空間部が複雑な空間形状を有していても当該空間形状に倣う蓄熱材５を極めて容易に形成できる。 It is difficult to enclose the heat storage material already gelled in the space shape of the packaging material 57 of the heat storage member 55. On the other hand, according to the manufacturing method of the heat storage member according to the present embodiment, since the heat storage material solution and the gelling material are sealed in the space portion of the packaging material 57 and then the gelled heat storage material 5 is formed, the packaging material Even if the space part 57 has a complicated space shape, the heat storage material 5 following the space shape can be formed very easily.
　図１１は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その６）を示している。図１１に示す蓄熱部材６０は、例えば、冷蔵庫の壁部や庫内の棚部材に配置したり、クーラーボックスの壁部に配置したりするだけでなく、布団、マット、自動車の座席のシートの内部に配置して使用できる。さらに、空調設備（エアコン）等にも使用できる。図１１（ａ）は蓄熱部材６０の平面図であり、図１１（ｂ）は図１１（ａ）に示す蓄熱部材を搭載した蓄冷エバポレータ２１０の斜視図である。図１１（ｃ）は図１１に示す蓄熱部材６０を搭載した蓄冷マット２１２を示す斜視図である。図１１（ａ）に示すように蓄熱部材６０は平面形状が長方形の薄い直方体形状をしている。蓄熱部材６０の長方形平面部の周辺部を封止した袋状の包装材６２の空間部内に蓄熱材５が収容されている。包装材６２の長方形平面には細長状（ストライプ状）の穴部６４が５列並んで開口されている。各穴部６４周囲は封止されている。包装材６２の空間部は平面方向に見てストライプ状に配置された５個の穴部６４を除く格子状に画定されている。複数の穴部６４は包装材６２の空間部の厚さを規定する厚さ規定部材として機能する。このため、図１１に示す蓄熱部材６０は、図６に示す蓄熱部材１０に比して周辺部と中央部の厚さの差を小さくできるので、蓄熱部材６０の長方形表面をより厚さが均一な平坦にすることができる。蓄熱部材６０の方が冷蔵庫の壁部や庫内の棚部材、あるいはクーラーボックスの壁部に高い密着性で容易に配置できる。 FIG. 11 shows a configuration example (No. 6) of the heat storage member manufactured by the method for manufacturing the heat storage member according to the present embodiment. The heat storage member 60 shown in FIG. 11 is not only arranged on a wall part of a refrigerator or a shelf member in a refrigerator or on a wall part of a cooler box, but also on a futon, a mat, or a seat of a car seat. Can be used inside. Furthermore, it can be used for air conditioning equipment (air conditioners). Fig.11 (a) is a top view of the heat storage member 60, FIG.11 (b) is a perspective view of the cool storage evaporator 210 carrying the heat storage member shown to Fig.11 (a). FIG.11 (c) is a perspective view which shows the cool storage mat 212 carrying the heat storage member 60 shown in FIG. As shown in FIG. 11A, the heat storage member 60 has a thin rectangular parallelepiped shape with a rectangular planar shape.

The space portion of the packaging material 62 is defined in a lattice shape excluding the five hole portions 64 arranged in a stripe shape when viewed in the plane direction. The plurality of holes 64 function as a thickness defining member that defines the thickness of the space of the packaging material 62. For this reason, since the heat storage member 60 shown in FIG. 11 can make the difference of the thickness of a peripheral part and a center part small compared with the heat storage member 10 shown in FIG. 6, the thickness of the rectangular surface of the heat storage member 60 is more uniform. Can be flat. The heat storage member 60 can be easily disposed with high adhesion to the wall portion of the refrigerator, the shelf member in the refrigerator, or the wall portion of the cooler box.
　さらに、包装材６２がストライプ形状をしているので、蓄熱部材６０を容易に折り曲げることができる。このため、図１１（ｃ）に示す蓄冷マット２１２を始めとして布団や自動車の座席シート等の、折り曲げたり丸めたりして使用する器具内に蓄熱部材６０を配置して用いることができる。また、ストライプ形状では風の通る隙間を多く設けることができるため、図１１（ｂ）に示す蓄熱エバポレータ２１０を始めとして空調設備（エアコン）等にも蓄熱部材６０を用いることができる。 Furthermore, since the packaging material 62 has a stripe shape, the heat storage member 60 can be easily bent. For this reason, the heat storage member 60 can be disposed and used in an appliance that is used by being folded or rolled, such as a cold storage mat 212 shown in FIG. In addition, since a lot of gaps through which the wind passes can be provided in the stripe shape, the heat storage member 60 can be used not only in the heat storage evaporator 210 shown in FIG.

On the other hand, according to the manufacturing method of the heat storage member by this Embodiment, since the heat storage material 5 and the gelled material which were made to enclose the heat storage material solution and the gelled material in the space part of the packaging material 62 are formed, a packaging material is formed. Even if the space portion 62 has a complicated space shape, the heat storage material 5 following the space shape can be formed very easily.
　図１２は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その７）を示している。図１２に示す蓄熱部材７０は首枕に用いられる。図１２（ａ）は蓄熱部材７０の斜視図であり、図１２（ｂ）は図１２（ａ）に示す蓄熱部材７０を収容する枕カバー２１４を例示している。図１２（ａ）に示すように蓄熱部材７０は断面が円形状や楕円形状の柱状体を所定の曲率で曲げた形状をしている。蓄熱部材７０の曲がった柱状体の包装材７２の空間部内に蓄熱材５が収容されている。包装材７２の柱状体の一底面部には、蓄熱材溶液とゲル化材料を投入した投入口を封止した封止部７６が形成されている。封止部７６の長さは、包装材７２内の蓄熱材５の封止部７６と同方向に測った長さより短い。 FIG. 12 shows a configuration example (No. 7) of the heat storage member manufactured by the method of manufacturing the heat storage member according to the present embodiment. The heat storage member 70 shown in FIG. 12 is used for a neck pillow. FIG. 12A is a perspective view of the heat storage member 70, and FIG. 12B illustrates a pillow cover 214 that houses the heat storage member 70 shown in FIG. 12A. As shown in FIG. 12A, the heat storage member 70 has a shape obtained by bending a columnar body having a circular or elliptical cross section with a predetermined curvature. The heat storage material 5 is accommodated in the space of the bent packaging material 72 of the columnar body of the heat storage member 70. On one bottom surface of the columnar body of the packaging material 72, a sealing portion 76 is formed that seals the charging port into which the heat storage material solution and the gelling material are charged. The length of the sealing part 76 is shorter than the length measured in the same direction as the sealing part 76 of the heat storage material 5 in the packaging material 72.
　蓄熱部材７０を枕カバー２１４に収納して蓄冷機能付きの首枕が完成する。蓄熱部材７０の包装材７２の空間形状にすでにゲル化した蓄熱材を封入することは困難である。これに対し本実施の形態による蓄熱部材の製造方法によれば、包装材７２の空間部に蓄熱材溶液とゲル化材料を封入してからゲル化させた蓄熱材５を形成するので、包装材７２の空間部が複雑な空間形状を有していても当該空間形状に倣う蓄熱材５を極めて容易に形成できる。 Storing the heat storage member 70 in the pillow cover 214 completes a neck pillow with a cold storage function. It is difficult to enclose the heat storage material already gelled in the space shape of the packaging material 72 of the heat storage member 70. On the other hand, according to the manufacturing method of the heat storage member according to the present embodiment, since the heat storage material 5 and the gelled material are sealed in the space portion of the packaging material 72 and the gelled heat storage material 5 is formed, the packaging material is formed. Even if the space portion 72 has a complicated space shape, the heat storage material 5 following the space shape can be formed very easily.
　図１３は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その８）を示している。図１３は、果物や鶏卵を一つずつ保護するとともに鮮度を保つために保冷する機能を備えた包装容器（パック容器）２１５の一部断面を示している。包装容器２１５は果物や鶏卵等の被包装物２１８を一つずつ収容可能な凹部が複数形成された一対の半容器２１６を対向させて構成される。一対の半容器２１６の対向面側には本実施形態の製造方法で製造された蓄熱部材８０、８２が貼付されている。蓄熱部材８０、８２は比較的薄いシート状の包装材に蓄熱材が収容されている。蓄熱部材８０は、一対の半容器２１６の対向面側のほぼ全面に凹部の形状に倣うように配置されている。このため、一対の半容器２１６を対向させて組み合わせると、包装容器２１５の内表面全体を蓄熱部材８０で覆うことができる。蓄熱部材８２は、凹部の蓄熱部材８０上に重ねて配置されている。蓄熱部材８２は、凹部に収容された被包装物２１８近傍をより保冷するとともに、被包装物２１８を保護する緩衝材としても機能する。 FIG. 13 shows a configuration example (No. 8) of the heat storage member manufactured by the method of manufacturing the heat storage member according to the present embodiment. FIG. 13 shows a partial cross-section of a packaging container (pack container) 215 having a function of protecting fruits and eggs one by one and keeping them cold to maintain freshness. The packaging container 215 is configured by facing a pair of half-containers 216 formed with a plurality of recesses capable of accommodating the articles 218 such as fruits and chicken eggs one by one. The heat storage members 80 and 82 manufactured by the manufacturing method of the present embodiment are attached to the opposing surface sides of the pair of half containers 216. In the heat storage members 80 and 82, the heat storage material is accommodated in a relatively thin sheet-like packaging material. The heat storage member 80 is disposed so as to follow the shape of the recess on substantially the entire surface of the pair of half containers 216 facing each other. For this reason, when the pair of half containers 216 are opposed and combined, the entire inner surface of the packaging container 215 can be covered with the heat storage member 80. The heat storage member 82 is arranged so as to overlap the concave heat storage member 80. The heat storage member 82 further cools the vicinity of the packaged item 218 accommodated in the recess, and also functions as a cushioning material that protects the packaged item 218.
　蓄熱部材８０、８２のような、複雑な包装容器２１５の内壁に倣う薄い蓄熱部材は、包装材の空間形状にすでにゲル化した蓄熱材を封入して製造するのは困難である。これに対し本実施の形態による蓄熱部材の製造方法によれば、包装材の空間部に蓄熱材溶液とゲル化材料を封入してからゲル化させた蓄熱材を形成するので、包装材の空間部が複雑な空間形状を有していても当該空間形状に倣う蓄熱材を極めて容易に形成できる。 It is difficult to manufacture a thin heat storage member, such as the heat storage members 80 and 82, that follows the inner wall of the complicated packaging container 215 by enclosing the heat storage material already gelled in the space shape of the packaging material. On the other hand, according to the manufacturing method of the heat storage member according to the present embodiment, since the heat storage material solution and the gelling material are sealed in the space portion of the packaging material and then the gelled heat storage material is formed, the space of the packaging material Even if the portion has a complicated space shape, a heat storage material that follows the space shape can be formed very easily.
　図１４は、本実施形態による蓄熱部材の製造方法により製造した蓄熱部材の構成例（その９）を示している。図１４は、魚２２０を一尾ずつ保護するとともに鮮度を保つために保冷する機能を備えた蓄熱部材９０を示している。蓄熱部材９０は例えば特定の魚体の輪郭形状に合わせた曲線形状を有する帯状の形状を有している。例えばマグロ漁船等の遠洋漁業では獲った魚の鮮度を保つために、大量の電気、燃料を使用して船内の冷凍庫を冷やしているが、蓄熱部材９０を魚２２０と魚２２０の隙間に入れて用いれば、燃料等の消費を軽減できる。漁船の魚の保管庫は容量も限られているため、魚の隙間に蓄熱材を無駄なく配置できることが好ましい。蓄熱部材９０によれば、魚体の輪郭形状に近い曲線形状を備えているので、効率よく魚を冷やすことができるとともに魚同士の接触を防止して魚体を保護することができる。 FIG. 14 shows a configuration example (No. 9) of the heat storage member manufactured by the method for manufacturing the heat storage member according to the present embodiment.
