〈産業上の利用分舒〉
本発明はクールボックス等の保冷に用いて好適な新規な
保冷用パック及びその使用方法に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application> The present invention relates to a novel cold pack suitable for use in keeping things cold, such as cool boxes, and a method of using the same.
〈従来の技術〉
例えば、クールボックス等の保冷を行う場合には、従来
水をビニール袋などにつめたものを使用するか、あるい
は市販の保冷材が使用されている。ここで、氷を使用す

発生するおそれがあり、また使用に際し手間がかかる等
の理由から、市販の保冷材が用いられることが多い。<Prior Art> For example, when keeping a cool box or the like cool, a plastic bag filled with water or a commercially available cold insulating material is conventionally used. Here, when using ice, there is a risk that the plastic bag will tear easily, especially if the ice melts, causing problems such as getting the contents of the cool box wet, and it may be time-consuming to use. Therefore, commercially available cold insulation materials are often used.
ところで、従来、市販されている保冷材は、ポリ容璧等
に液状の冷媒を封入したものやゼリー状の冷媒を袋に封
入したもので、そのまま冷凍した後使用することができ
るものである。By the way, conventionally commercially available cold insulation materials include those in which a liquid refrigerant is sealed in a plastic container or the like, or those in which a jelly-like refrigerant is sealed in a bag, which can be used as is after being frozen.

あるので、輸送コストがかなり大きくなるという問題も
あった。<Problems to be solved by the invention> As mentioned above, conventionally commercially available cold insulation materials can be used by being frozen as is, but in any case, the shape is fixed at least after freezing. Therefore, there was an inconvenience that space had to be reserved for the cold insulation material in the cool box. In addition, since the commercially available product itself is bulky and heavy, there is also the problem that transportation costs are considerably high.
本発明はこのような事情に鑑み、冷凍された状態でもあ

特徴とする。Means for Solving the Problems〉 The cold pack of the present invention that achieves the above objects uses a water-absorbing sheet made of a super absorbent resin formed into a sheet shape through a valve, water-absorbing material such as water-absorbing paper, and a water-permeable sheet. It is characterized by being sealed in a water-permeable sheet, and its usage is by sealing a water-absorbent sheet made of super absorbent resin into a sheet shape through a water-absorbing material such as a valve or water-absorbing paper into a water-permeable sheet. The pack absorbs water and is used for cold storage after being refrigerated or frozen.
く実 施 例〉 以下、本発明を好適な実施例に基づいて説明する。Practical example The present invention will be explained below based on preferred embodiments.
第1図は本発明の一実施例にかかる保冷用パックの斜視
図である。同図に示すように、この保冷用パック1は、
透水性シート2内に複数枚の吸水シート3を封入したも
のである。FIG. 1 is a perspective view of a cold pack according to an embodiment of the present invention. As shown in the figure, this cold pack 1 is
A plurality of water-absorbing sheets 3 are enclosed within a water-permeable sheet 2.
ここで透水性シート2とは不織布2合成紙などで水を透
過するとともに水を含んでもある程度の強度を有するも
のである。また吸水シート3とはパルプ、吸水紙等の吸
水材料を介して高吸水性樹脂がシート状に成形されたも
のである。更に評言すると、°例えばパルプ間に高吸水
性樹脂を挟持した状態で押し固めたもの、あるいは吸水
紙の間に高吸水性樹脂を挟持したものなどをいう。ここ
で、高吸水性樹脂自体の各層はかなり薄くして水を吸収
し易くするのがよく、必要に応じて多層構造にするのが
よい。また、平面上に薄く挟持された高吸水性樹脂の片
寄りを防止するために、その厚さに直交する方向に区画
するために成形時などに特に強く圧縮するなどすること
により区画部3aを形成するのがよい。Here, the water-permeable sheet 2 is a nonwoven fabric 2, such as synthetic paper, that allows water to pass through it and has a certain degree of strength even when it contains water. The water-absorbing sheet 3 is formed by molding a highly water-absorbent resin into a sheet through a water-absorbing material such as pulp or water-absorbing paper. More specifically, it refers to, for example, one in which a super absorbent resin is sandwiched between pulps and compacted, or one in which a super absorbent resin is sandwiched between water absorbent papers. Here, each layer of the superabsorbent resin itself is preferably made fairly thin so that it can easily absorb water, and if necessary, it is preferable to have a multilayer structure. In addition, in order to prevent the superabsorbent resin sandwiched thinly on a flat surface from shifting, the partitioned portion 3a is compressed particularly strongly during molding in order to partition it in a direction perpendicular to its thickness. It is better to form.
このような吸水シートは本実施例のように複数枚積層す
ることもできるが例えばうずまき状に巻いて筒状の保冷
パックとすることもできる。A plurality of such water-absorbing sheets can be laminated as in this embodiment, but they can also be rolled into a spiral shape to form a cylindrical cold pack, for example.
なお、高吸水性樹脂としては例えば自重の数百倍程度の
吸水力を有し、少々の圧力では吸水した水を離さない能
力を持つものであれば何れを用いてもよく、具体的には
天然のでんぷん・アクリル酸系高吸水性樹脂、合成化学
品・アクリル酸系高吸水性樹脂、カルボキシ・メチル・
セルロース系高吸水性樹脂などを挙げることができる。Note that any superabsorbent resin may be used as long as it has a water absorbing power of several hundred times its own weight and has the ability to retain absorbed water even under a small amount of pressure. Natural starch/acrylic acid-based super absorbent resin, synthetic chemicals/acrylic acid-based super absorbent resin, carboxy/methyl/
Examples include cellulose-based super absorbent resins.
本発明の保冷用パック1は自重の100〜200倍の水
を吸収できろように設定するので、吸水時には主に吸水
シート3の厚さ方向に膨張することになるので、この膨
張分を考慮して透水性シート2の大きさを設定する必要
がある。Since the cold pack 1 of the present invention is designed to be able to absorb 100 to 200 times its own weight of water, it will expand mainly in the thickness direction of the water absorbent sheet 3 when absorbing water, so this expansion should be taken into consideration. It is necessary to set the size of the water-permeable sheet 2.
本発明の保冷用パック1を使用する場合には、まず透水
性シート2を通して吸水シート3に水を十分吸水させて
第2rIAに示す状態とした後冷[11に入れる。そし
て十分冷凍した後、例えばクールボックスなどの保冷に
供する。When using the cold pack 1 of the present invention, first, the water-absorbing sheet 3 is made to sufficiently absorb water through the water-permeable sheet 2 to bring it into the state shown in the second rIA, and then placed in a cold state [11]. After sufficiently freezing, it is stored in a cool box, for example.
ここで、本発明にかかる保冷用パックはたとえ冷凍して
もある程度自由に変形することができるので、クールボ
ックス内のあきスペースに収納し易いという長所を有し
ている。Here, the cold pack according to the present invention can be deformed freely to some extent even when frozen, so it has the advantage that it can be easily stored in a free space in a cool box.
さらに、保冷すべき物品が細長い場合、これに巻付ける
使用方法、物品が薄い場合ファンフォールド状に連続し
て交互にはさむ使用方法を可能とする長所を有する。ま

とえ透水性シート2が破れてもクールボックス内が水び
たしになることもない。なお、この保冷用パックは水を
吸収させた後、あるいは冷凍した浸水を透過しない樹脂
製袋などに入れて用いてもよい。Furthermore, it has the advantage that if the article to be kept cold is long and narrow, it can be wrapped around it, or if the article is thin, it can be used by continuously and alternately sandwiching the article in a fanfold shape. Moreover, since water does not release even after the cold insulation effect is lost, even if the water-permeable sheet 2 is torn, the inside of the cool box will not be flooded with water. Note that this cold pack may be used after absorbing water or by being placed in a resin bag that is impermeable to frozen water.
〈発明の効果〉
以上説明したように、本発明によれば、冷凍後もある程
度自由に変形可能で使用し易く、しかも、使用するまで
の軽量化、省スペース化を図ることができるので、輸送
コストが大幅に低減できるという効果も奏する。<Effects of the Invention> As explained above, according to the present invention, even after freezing, it can be deformed to some extent and is easy to use, and furthermore, it is possible to reduce weight and save space until it is used, so it is easy to transport. This also has the effect of significantly reducing costs.
