することによって、繰返し使用出来る路用袋に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bag for road use, and more particularly, by swelling a water-absorbing polymer with liquid due to an endothermic chemical reaction between a water-containing agent and a coolant, the swollen polymer inside the bag remains unchanged even after quenching. This invention relates to a road bag that can be used repeatedly by cooling the bag.

に提供出来ぬ問題を生じていた。BACKGROUND ART Conventionally, there have been many road bags known as quenched bags that use the instantaneous heat-absorbing effect of mixing a coolant and water inside the bag to cause an endothermic or chemical reaction. However, once the coolant inside the bag and the water undergo an endothermic chemical reaction, these rapid cooling packs do not cause another chemical reaction, so they are sold as disposable products and cannot be provided at low prices. It was causing a problem.
そこで発明者は、これら問題点を解決する為、含水剤と

繰返し冷用枕等として使用することを目的とする路用袋
を提供する。In order to solve these problems, the inventor developed a road bag that swells the polymer by absorbing the liquid produced when the water-containing agent and the coolant undergo an endothermic chemical reaction. By cooling the polymer itself,
To provide a road bag intended for repeated use as a cold pillow, etc.
斯かる目的を達成する為１本発明の路用袋は含水剤を封
入した内袋を冷却剤と吸水ポリマーとともに外袋に封入
したことを特徴とするものである。In order to achieve the above object, the road bag of the present invention is characterized in that an inner bag containing a water-containing agent is enclosed in an outer bag along with a coolant and a water-absorbing polymer.
以下、本発明の路用袋について詳細に説明する。Hereinafter, the road bag of the present invention will be explained in detail.
第１図は、本発明に係る路用袋ｌの断面概略図である。FIG. 1 is a schematic cross-sectional view of a road bag l according to the present invention.
路用袋ｌは、内部に含水剤２を封入した内袋３と冷却剤
４及び吸水ポリマー４１とを外袋５によって封入して構
成されている。The road bag 1 is constructed by enclosing an inner bag 3 containing a water-containing agent 2, a coolant 4, and a water-absorbing polymer 41 with an outer bag 5.
この含水剤２は、水や含水化合物結晶、例えば硫酸ナト

入した内袋３は、使用時に手等による外力によって破裂
する程度の強度を有する合成樹脂シートによって形成さ
れている。As the water-containing agent 2, water or crystals of a water-containing compound such as sodium sulfate decahydrate are used. Further, the inner bag 3 containing the water-containing agent 2 is formed of a synthetic resin sheet having enough strength to burst due to external force applied by hand or the like during use.
一方、これら内袋３とともに外袋５に封入された冷却剤
４は、含水剤２と反応して吸熱化学反応を起こす粉９粒
状の冷却剤であり、通常硝酸アンモニウムと尿素を単独
あるいは混合物で用いる。On the other hand, the coolant 4 enclosed in the outer bag 5 together with the inner bag 3 is a powder-like coolant that reacts with the water-containing agent 2 to cause an endothermic chemical reaction, and usually uses ammonium nitrate and urea alone or in a mixture. .
また冷却剤４には、アクリル酸重合物（ポリアクリレー

じめ混合した状態にしておいてもよいし、吸水性ポリマ
ー４１を別個の袋体に封入しておくものでもよい。いず
れにしても、吸熱化学反応後直ちに混合される状態であ
ればよい。In addition to the above-mentioned water-absorbing polymers, there are polyvinyl alcohol-based ones and maleic anhydride-based ones, but these react with the above-mentioned coolant to cause secondary decomposition to produce ammonia and acetic acid. Therefore, it is not appropriate to use it directly. The coolant 4 and the water-absorbing polymer 41 may be mixed in advance, or the water-absorbing polymer 41 may be sealed in a separate bag. In any case, it is sufficient that they are mixed immediately after the endothermic chemical reaction.

れる。The outer bag 5 enclosing these items must have enough strength to not rupture itself when an external force is applied from outside the surface of the inner bag 3 to cause the inner bag 3 to rupture. For that reason,
A synthetic resin film material such as aluminum laminate is usually used.
以上の様に構成された路用袋ｌを、実際に使用する場合
について更に詳しく説明する。The actual use of the road bag 1 constructed as described above will be explained in more detail.
先ず、緊急冷却を要する際に、路用袋ｌの外部から力を
加えて内袋３を破裂させる。この内袋３が破裂すると、
その内部に封入にされていた水等の含水剤２が冷却剤４

袋５の外表部の熱が奪われ、路用袋ｌの冷却作用が顕在
化する。First, when emergency cooling is required, force is applied from outside the road bag 1 to rupture the inner bag 3. If this inner bag 3 ruptures,
A water-containing agent 2 such as water sealed inside is a coolant 4.
Mix with. The coolant 4 containing ammonium nitrate and urea alone or as a mixture causes an endothermic chemical reaction when melting into the water-containing agent 2 and absorbs heat from the surroundings. As a result, heat is removed from the outer surface of the outer bag 5, and the cooling effect of the road bag 1 becomes apparent.
しかもこの時、含水剤２と冷却剤４の反応によって生じ

リマ−４１自体が膨潤してゲル化状態になる。Moreover, at this time, the water-absorbing polymer 41 absorbs the liquid produced by the reaction between the water-containing agent 2 and the coolant 4, and the water-absorbing polymer 41 itself swells and becomes gelled.

て繰返し使用することができる。Therefore, after the use of emergency cooling, the outer bag 5 is filled with gelled polymer, resulting in the formation of a road bag 1 with a rich soft feel and low fluidity. If this road bag 1 is placed in a refrigerator or the like and the gelled polymer itself is cooled and frozen, the road bag 1 can be used repeatedly as a cooling pillow or the like.

度氷枕代用として使用することが可能となる。In other words, even after being used as a road bag for emergency cooling,
If the road bag itself is cooled and frozen in a refrigerator for several hours before use, it can be used again as an ice pillow when necessary, such as for a good night's sleep or when you have a fever.
次に、本発明の路用袋について具体的な実施例に基づき
その効果を説明する。Next, the effects of the road bag of the present invention will be explained based on specific examples.
含水剤、冷却剤及び吸水性ポリマーの混合比率は次表１
の如く、含水剤１００重量部に対し、冷却剤は２００〜
３００重量部、吸水性ポリマーは３０〜１００重社部で
ある。The mixing ratio of water-containing agent, coolant, and water-absorbing polymer is shown in Table 1 below.
As shown in the figure, the amount of coolant is 200 to 100 parts by weight of water-containing agent.
300 parts by weight, and the water-absorbing polymer is 30 to 100 parts by weight.
又、冷却剤を構成する尿素と硝酸アンモニウムの混合比
率は、冷却効果の最も高い混合比率とし、実験結果によ
れば、硝酸アンモニウム １００重量部に対して尿素を
７０〜１００重量部とする場合が最も良い冷却効果を発
揮する。In addition, the mixing ratio of urea and ammonium nitrate that constitute the coolant should be the mixing ratio that provides the highest cooling effect, and according to experimental results, it is best to use 70 to 100 parts by weight of urea to 100 parts by weight of ammonium nitrate. Demonstrates cooling effect.
一方、吸水ポリマーは、液分を吸水して膨潤し、ゲル化
状態となるので、このゲル化後の語調度合によって決定
される。On the other hand, a water-absorbing polymer absorbs liquid, swells, and enters a gelled state, so it is determined by the degree of tone after gelling.
すなわち、３０重量部以下であると語調性が小さくなっ
て、袋体外表面のソフト感触が大きくなり過ぎる。That is, if it is less than 30 parts by weight, the tonality will be poor and the soft feel of the outer surface of the bag will be too large.
また、 １００重量部以上であると逆に語調性が大きく
なり、袋体外表面は硬質化してソフト感触が喪失する。On the other hand, if it is more than 100 parts by weight, the tonality will be increased, and the outer surface of the bag will become hard and lose its soft feel.
更に材料コストの上昇にもなる。Furthermore, it also increases material costs.
これ等からして通常は、５０〜７０重量部程度が最も効
率の良い混合比率となる。Considering these factors, the most efficient mixing ratio is usually about 50 to 70 parts by weight.
表−１
この様に含水剤を封入した内袋を、冷却剤と吸水ポリマ

内袋を破裂させて吸熱化学反応を起させる際に冷却作用
を生ぜしめるとともに、その反面吸水性ポリマーの吸水
作用が含水剤と冷却剤との反応を遅延させることにもな
る。Table 1 As described above, the inner bag containing the water-containing agent is enclosed in the outer bag along with the coolant and the water-absorbing polymer.
When the inner bag is ruptured to cause an endothermic chemical reaction, a cooling effect is produced, and on the other hand, the water-absorbing effect of the water-absorbing polymer also delays the reaction between the water-containing agent and the coolant.
この遅延作用は、冷却を瞬時に終了させることなく、経
時的に冷却を大きくしてゆき、しかも冷却を持続させる
効果をもたらす。This delay effect has the effect of increasing cooling over time without terminating the cooling instantaneously, and furthermore, making the cooling continuous.
更に、その除虫じる液分を吸水ポリマーに吸水させてゲ
ル化状にするので、外袋内に充溢したゲル化状のポリマ
ーを再度冷却することによって当該冷用袋を繰返し使用
することが出来るものである。Furthermore, since the insect-repelling liquid is absorbed into the water-absorbing polymer and turned into a gel, the cooling bag can be used repeatedly by cooling the gelled polymer that has filled the outer bag again. It is possible.
以上の様に本発明の冷用袋は、救急冷却時にその冷却効
果を円滑に発揮して使用される丈でなく、その使用後に

る。As described above, the cold bag of the present invention is not long enough to be used by smoothly exerting its cooling effect during emergency cooling, and if it is kept cooled in a refrigerator etc. after use, it can be used repeatedly as an ice pillow etc. It is extremely practical and has a high practical effect.
