断熱性包装体に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like material having a heat insulating property by a multi-layer structure, or a heat insulating package as a bag or a box.

ることができる。2. Description of the Related Art As means for imparting heat insulation to a sheet-shaped material, a radiant heat reflection layer is provided with aluminum foil or the like,
Some include foamed resin. Examples of the latter are Jpn. Kokoku Sho 60-7147 and Jikkaihei 1-16.
No. 3119, Japanese Utility Model Publication No. 2-37746, and the like.

いる。[0003] Of these, Japanese Utility Model Publication No. 60-7147 proposes a double-sided paper-bonded foamed sheet in which foamed synthetic resin particles are uniformly arranged and interposed between a pair of papers. In addition, Japanese Utility Model Laid-Open No. 1-163119 and Japanese Utility Model Publication No. 2-37746 propose that a foamed resin layer is provided on a corrugated fiberboard core or liner.

【発明が解決しようとする課題】上記の断熱性包装体
は、いずれも紙と紙との間に発泡合成樹脂を介在させ、
発泡による断熱性を期待したものであるが、その材料が
水に溶けない合成樹脂であるために、使用済となったと
きに、省資源のための再生用として提供できなく、さら
に、製造や断熱性についても問題があった。In any of the above heat insulating packages, a foamed synthetic resin is interposed between papers,
Although it is expected to have heat insulating properties due to foaming, it cannot be provided for recycling to save resources when it is used because it is a synthetic resin that does not dissolve in water. There was also a problem with heat insulation.
【０００５】即ち、上記従来例の紙層は二層（一対の
紙）であったため、発泡性接着剤の発泡倍率には限界が
あり、最大に発泡しても塗布量の２倍以下の厚みにしか
ならず、期待した断熱効果が得られないという問題があ
った。That is, since the conventional paper layers are two layers (a pair of paper sheets), the expansion ratio of the expandable adhesive is limited, and even if the foaming is maximum, the thickness is not more than twice the coating amount. Not only that, but there was a problem that the expected heat insulating effect could not be obtained.
【０００６】製造について、発泡合成樹脂を粒子として
介在させたものでは、紙と紙との間に予め粒子として成

泡合成樹脂層と紙との結合により硬直するために、柔軟
性に劣り、繊細な包装には不適であった。Regarding the production, in the case where the foamed synthetic resin is interposed as the particles, a very troublesome manufacturing process of evenly sandwiching the preformed particles between the paper and adhering them is performed. Therefore, there is a problem that productivity is poor. Further, in the case where the foam synthetic resin is interposed as a layer, the space between the paper is filled with the foam resin without a gap, so that an air layer effective for heat insulation does not occur between them, and this also rationalizes the heat insulation. It cannot be provided, and since it is cured by bonding the foamed synthetic resin layer and paper, it has poor flexibility and is unsuitable for delicate packaging.
【０００７】この発明は、上記のような実情に鑑みて、
再生のために何ら支障がなく、そのままリサイクル処理
できることはもとより、製造が容易であり、断熱性と柔
軟性とを兼備した断熱性包装体を提供することを目的と
した。The present invention has been made in view of the above circumstances.
The object of the present invention is to provide a heat-insulating package which has no problem for recycling and can be recycled as it is, is easy to manufacture, and has both heat insulating property and flexibility.

【課題を解決するための手段】上記の目的を達成するた
めに、この発明は、三枚以上の紙を発泡性接着剤により
多層構造に積層して成る断熱シート、断熱紙器、断熱箱
のいずれかである断熱性包装体を提供するものである。In order to achieve the above object, the present invention provides a heat insulating sheet, a heat insulating paper container, or a heat insulating box, which is formed by laminating three or more sheets of paper in a multilayer structure with a foaming adhesive. The present invention provides a heat insulating package.

ることができる。When the foaming adhesive is based on starch, or when three or more sheets of paper are partially bonded by the foaming adhesive to form a multi-layered structure, at least one side When the heat reflection layer is provided on at least one of the both surfaces and the inner surface of the layer, the object of the present invention can be achieved more preferably.

りいっそう好ましく達成することができる。In addition, it has a multi-layer structure in which three or more sheets of paper are partially adhered and an air layer is provided between them, and a starch which has not been gelatinized is used as a partial adhesive and a foaming agent is mixed therein. The object of the present invention can be achieved even more preferably when the foamable adhesive consisting of the above is used and the adhesion and the foaming are simultaneously performed by heating.

反射層としては、印刷加工によるものが安価で、本発明
の目的達成には充分である。The foaming adhesive is preferably a combination based on starch, in which Poval and a foaming agent are mixed. Poval is preferable since it is water-soluble, easily forms a film, mixes with starch to promote the foaming action, and is easily adapted to the natural environment even after use. Further, the adhesive may be foamed by being bonded with a foamable adhesive and then heated, or a foamable adhesive in which a material that has been foamed beforehand is mixed may be used. The latter is more preferable because it is easy to form a uniform flat surface. It should be noted that the heat-reflecting layer produced by printing is inexpensive and sufficient for achieving the object of the present invention.

上する。[Operation] Increasing the thickness is effective for improving the heat insulation effect. As a means of increasing the thickness, by increasing the number of paper layers, the foam layer of the expandable adhesive also becomes a multilayer, and as a result, the thickness increases and the heat insulating effect can be increased. Further, even if the thickness is the same, the heat insulating effect is greater when the number of paper layers is three, than when the number of paper layers is three. The layer becomes paper / foamable adhesive / paper / foamable adhesive / paper,
The presence of the paper layer (paper liner) in the middle not only improves the strength, but also makes it difficult for heat to escape and the heat insulating property is significantly improved. In addition, the heat insulating effect is further improved in the case where the heat reflection layer is interposed and the case where the multilayer is formed by partial adhesion.

ルゲート形状も容易に形成できるという特長がある。As the foaming adhesive, a starch-based starch which has not been gelatinized yet and a foaming agent mixed therein are used, so that the adhesion and the expansion thereof are performed at the same time. A large air layer can be formed between the paper and the paper without specially interposing particles as shown in the conventional example. In addition, since the adhesive is a foaming adhesive, a gap can be created between the papers, which makes it easy to bend the cabling and to easily form a corrugated shape such as a corrugated fiber core. There are features.

いる。The heat insulating property is mainly due to the multi-layered structure of paper, this air layer, and the foaming property of the adhesive, and the heat insulating property of five layers or more is particularly excellent. In addition, in this case, one layer means a single sheet of paper, and in addition to general paper, if it is an object to be bonded by the above-mentioned foaming adhesive, a corrugated cardboard is formed. Includes core and liner. Also, the heat insulation varies depending on the basis weight of the paper,
Particularly, those having 100 g / m 2 or more are particularly excellent in heat insulating effect.

である。FIG. 1 and FIG. 2 show an example implemented as a heat insulating sheet, and the heat insulating package P has three papers 1, 1, 1 by partially adhering each paper 1, 1 In order to secure the thickness of the air layer 3, the partial adhesive 2 is foamed, and based on starch and poval so that it does not hinder recycling. A mixture with a foaming agent is used.
The production of the heat insulating package P is as follows, for example.

り膨張する。As the starch, corn starch generally used in the production of corrugated board was used. In other words, starch that has been gelatinized is mixed with starch that has not yet been gelatinized,
Based on it, using a mixture of Poval and a foaming agent, apply it partially on the paper 1 by a screen printing method, while sticking the three papers 1, 1, 1 Dive between the heating roller or heater.
Then, in the foaming adhesive between the papers 1 and 1, the starch is gelatinized by heating, and the gelatinization removes water to remove the water from both papers 1 and 1.
Is rapidly adhered, and at the same time, foam is generated by the foaming agent and expanded by foaming.

ではない。When the heat-insulating package P is constructed in this way, it is used for packaging foods, for example, so-called other lunch boxes and other buns. Alternatively,
It can also be used as a material for insulating paper containers and insulating boxes.
The partial adhesive 2 is formed as dots or particles, but the shape thereof is not particularly limited, such as linear, zigzag, and cross-shaped.

すると、さらに断熱性を高めることができる。FIG. 3 shows another example implemented as a heat insulating sheet, and the heat insulating package P has a three-layer structure of paper in the above-mentioned case, but in this case, it is an irregular four-layer structure. The corrugated paper 1a having the same structure as that of the corrugated fiberboard core was used for one of them. With this, the heat insulating property can be further enhanced.

そのまま有効に供することができる。Since the foaming adhesive for laminating papers on each other is made of starch as a natural substance and mixed with water-soluble poplar, when regenerated,
Since the adhesive easily melts, it can be effectively used as it is for recycling treatment as a material that is kind to the earth when it is used.

る。When the laminated structure of paper is a multi-layered structure of three or more layers and partial adhesion is used, the air layer is kept thick because the expandable adhesive agent interposed therebetween expands due to foaming. Since it is easy and air is retained in the partial adhesive itself, it exhibits extremely high heat insulation.
