JPH0522540U - Multi-layer sheet regenerator - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] A multi-layered type for the purpose of reducing the amount and weight of the cool storage agent to eliminate transportation difficulties and maintaining the cool effect of the cool storage agent for a long time. Sheet-shaped cool storage agent. [Structure] Bags made of water-absorbing material such as non-woven fabric, and bags (2) and (4) containing water-absorbing polymer inside, made of the same material on both sides. A multi-layered sheet type cool storage agent in which a bag (3) containing the water-absorbing polymer is sandwiched in the middle and sealed in a non-water-supplying bag such as a plastic bag equipped with a check valve injection port. [Effect] At the time of use, water is supplied from the injection port (5) with a stop valve of the present invention, and the bags (2), (3), (4) containing the polymer completely absorb the water, expand and freeze. When it melts,
It begins to melt from the outside, and after melting, the bag with a high melting point inside begins to melt. Therefore, since the freezing time can be long, the cold storage effect can be maintained for a long time.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This has become possible due to the long-lasting effect of a cold storage agent for the transportation and storage of fresh foods that require long-term cold storage. In addition, the transport of the regenerator itself is in sheet form, so it is lightweight, thin, and simple.

[0002]

[Prior Art]

 Since the conventional regenerator is one container containing the regenerator, it is affected to the inside as the surface melts and loses its effect in a short time. Also, since the solution was enclosed from the beginning, the amount was large and heavy.

[0003]

[Problems to be solved by the device]

 In order to have a long-term effect with the conventional regenerator, it was necessary to put a large amount of regenerator or put it in a box with high heat retention. In addition, because of its large weight, it was difficult to transport the cold storage agent.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, a bag (1) made of a non-water-absorbing material such as a plastic bag with a water injection port with stop valve (5) as shown in FIG. A bag (2) or (4) made of a water-absorbing material such as a non-woven fabric is filled with a water-absorbent polymer (6), and a bag (3) made of the same material has a slightly higher melting point. A multi-layered sheet type cool storage agent which is set by enclosing the bag containing (7) in the center and sandwiching it between (2) and (4) in (1) on both sides.

[0005]

[Action]

 The usage of this invention is as shown in FIG. 3, when water is supplied from the water injection port (5), the water-absorbing polymer ((2), (3), (4)) into which the water has soaked into the bag ( 6) and (7) absorb water, expand and become a gel, and (2), (3) and (4) become their own cool storage agents, and a cool storage agent layer is formed as shown in Fig. 4. The supplied water does not flow back through the check valve water supply port (5), but is absorbed by (2), (3), and (4) to form a multi-layered cold storage agent.

[0006]

【Example】

 As shown in Fig. 4, when a multi-layered cold storage agent is frozen and brought into contact with fresh food that requires cold storage, the heat of fusion of the cold storage agent is used to produce a cold storage effect. After the cold storage agents in the bags of (4) and (2) have finished melting, the melting point of the cool storage agent in the central bag (3) is high, so that it starts melting in the next stage, and the effect of maintaining the cold insulation effect is used A multi-layered sheet type cool storage agent that is intended to maintain the effect of cold storage for a long time and is easy to transport because it is light and thin in a sheet shape before injecting water.

[0007]

[Effect of the device]

 In the present invention, the disadvantage that the frozen state of the conventional cold storage agent took a short time was solved by stacking multiple layers of the cold storage agent with different melting points. The problem that was difficult to solve is that the multi-layered sheet type cold storage agent was solved by transporting it in a sheet form and pouring water into it when using it.

Claims (1)

[Scope of utility model registration request] 1. A bag in which a water-absorbent polymer is enclosed in a bag made of a water-absorbent material such as a non-woven fabric, and a bag in which a water-absorbent polymer having a slightly higher melting point is enclosed on both sides, is sandwiched in the center, and the outside Is a cool storage agent installed in a bag made of a non-water absorbent material such as a plastic bag with a water inlet that functions as a check valve, and is built in by injecting water from the water inlet at the time of use. Also, water permeates into each bag, and the water-absorbent polymer absorbs the water and expands, and each bag serves as its own cool storage agent. If this is frozen and used as a cool storage agent, the cool storage agent in the two outer bags will melt, and then the cool storage agent in the center will melt due to the difference in melting point to maintain a long-term cool storage effect. A multi-layered sheet regenerator for the purpose.
