The present invention relates to a disposable cold storage body made of at least two kinds of water-absorbing polymer agents having different speeds, and a method for using the same.

冷体の使用に供する使い捨て蓄冷体がある。(B) Conventional technology Conventionally, a cold storage body is formed of a sheet-like body in which a water-absorbing polymer agent is encapsulated, at least a portion of which is made of a water-permeable nonwoven fabric, etc., and the cold storage body is heated without pouring water into the cold storage body. When brought into contact with water, water permeates through the surface of a water-permeable material, and after the water-absorbing polymer agent absorbs water, it freezes, and is used as a cold storage object.

When the frozen water-absorbing polymer agent is thawed, part of the free water other than hydration water absorbed by capillary action and osmotic pressure phenomenon is released by pressurization or the like. As a result, water droplets adhere to the surface nonwoven fabric of the cold storage body, resulting in the cold storage body being contaminated with water.

からの逆送水による蓄冷体外部への流水を防止する。(E) Action: When a bag is made of at least two types of water-absorbing polymer agents with different water-absorbing speeds and is covered with non-woven fabric, water permeates through the surface of the bag in a short period of time, and the water-absorbing polymer agent with different water-absorbing speeds is used when the cold storage body is thawed. A part of the free water of the fast water-absorbing polymer is released from the same polymer, but it is captured by the water-absorbing polymer with a slow water absorption rate that has not yet completely absorbed the water, resulting in reverse water absorption from nonwoven fabrics, etc. Prevents water from flowing outside the cold storage body due to water supply.

定法はティーバッグ法によった。(F) Example A mixture of 2.0 g of sodium acrylate polymer, a water-absorbing polymer agent with a fast water absorption rate, and 0.5 g of an EVA resin compound, a water-absorbing polymer agent with a slow water absorption rate, was permeable through a single-sided sheet. The disposable cold storage body shown in Fig. 1 was created by wrapping a polypropylene nonwoven fabric made of a transparent material and a sheet on the other side in a polyethylene film made of a non-water permeable material, and bonding the periphery using a thermal bonding method. (25°C) After being immersed in water for 5 minutes, it was frozen in a -20°C freezer for 24 hours. Two kinds of water-absorbing polymers with different water absorption rates in the cold storage body per 1.0 g of 25°C tap water. The relationship between the amount of water absorbed and the water absorption time is shown in Figure 2. The water absorption capacity was measured by the tea bag method.
第２図から明らかなように、吸水速度の速い吸水性高分

高分子剤がその吸水能の１００％まで達するのに対して
、この時点で他方の吸水速度の遅い吸水性高分子剤の吸
水量は未だその吸水能の２５％であった。As is clear from Figure 2, a water-absorbing polymer agent with a fast water absorption rate absorbs 400 times as much tap water in 5 minutes and reaches equilibrium, but a water-absorbing polymer agent with a slow water absorption rate absorbs tap water in 5 minutes. It absorbed 50 times more water, up to 200 times more water in 60 minutes, and then reached an equilibrium state. In other words, the amount of water absorbed by the water-absorbing polymer agents after 5 minutes of immersion in the cold storage body is that one of the water-absorbing polymer agents, which has a faster water absorption rate, reaches 100% of its water absorption capacity, while the other water-absorbing agent reaches 100% of its water absorption capacity at this point. The amount of water absorbed by the slow water absorbing polymer agent was still 25% of its water absorption capacity.

It was placed in a 200 mm x 200 [11 m H], sealed, and stored in a constant temperature bath at 30°C. The temperature inside the same container after 10 hours of storage was 5°C as seen in Figure 3.

The cold storage body taken out from the same container was thawed at room temperature and the degree of wetting of the surface of the nonwoven fabric of the water permeable material was examined, but no wetting due to reverse water permeation from the surface of the nonwoven fabric was observed.
