Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cold storage member used to store fresh food such as fresh fish when the fresh food is transported as chilled flights.

[0002]

[Prior art]

 Conventionally, when fresh foods such as fresh fish are transported from a market to a remote sales location, the fresh foods are transported together with a gel-type cold storage agent in Styrofoam in order to prevent deterioration and deterioration of the fresh foods. It is housed in a transport case, the opening of the transport case is closed with a styrofoam lid, and after packing, it is mounted on a vehicle. In addition, since the gel-type regenerator has a long cool-storage time, it is practically effective for transporting fresh food products to remote locations, and is easy to handle. It is also widely used for transporting fresh food and is being used in large quantities.

[0003] On the other hand, among the fresh food products, for example, squid is, as shown in FIG. 13 is placed, and the upper opening end of the transport case 11 is covered with a Styrofoam lid 14 for packing and transporting.

[0004]

[Problems to be solved by the invention]

 However, the conventional regenerator is bag-shaped, and has problems in shape retention during freezing and length of freezing time. Furthermore, the material of the cold storage agent is mixed with a water-absorbing polymer to maintain its shape, which lowers the efficiency of cold storage and requires disposal after use as garbage, which incurs disposal costs for commercial use. For household use, clogging may occur when drained into sewage. In addition, after the perishable food product is taken out of the transport case at the home or the supermarket where the perishable food product is received, the gel-type regenerator is converted into industrial waste which is not easily incinerated, and is then discharged from the transport case. They are taken out and disposed of as they are, causing the surrounding environment to deteriorate.

When the squid as described above is directly placed on the ice laid in the carrying case 11, the flesh color of the portion that comes into contact with the ice is changed to white and the freshness is easily lowered, In addition, it is necessary to increase the ice capacity and to increase the thickness of the carrying case in consideration of the rapid melting, which increases the weight and shape of the baggage and reduces the amount of melted water. There is a problem that it is necessary to separately provide a drain hole for discharging at the bottom of the carrying case 11.

[0006] The present invention solves the above-mentioned problem, and has high utility value as a cool storage means, and does not produce industrial waste after taking out fresh food from a transport case, thereby reducing the global environment. It is an object of the present invention to provide a cold storage member that can provide a gentle cold storage member and that can safely transport perishable food products without causing deterioration or freshness deterioration.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, in the cold storage member according to the invention of claim 1, water contained in the container is frozen to form ice, and the opening of the container is closed and sealed with a sheet material. The configuration is as follows. As a result, fresh foodstuffs stored in the transport case on which the cool storage member is spread can be stably stored for a relatively long time, and after the fresh foodstuffs are taken out of the transport case, the opening is opened. By removing the blocking sheet material, the water in the container can be discharged as it is, and the remaining container can be recycled.

In the cold storage member according to the present invention, the container and the sheet member are made of a flexible plastic. As a result, the fresh food can be efficiently cooled without directly contacting the ice in the transport case, and the cold storage member can be easily handled. In addition, the unit price can be reduced as compared with the case where a gel-like regenerator is used, and the regenerator members can be manufactured quickly and in large quantities.

Further, the cold storage member according to the present invention stores water in a container, freezes the water, and then adheres the sheet material to the periphery of the opening of the container so as to close the opening. In addition, the containers are shaped such that when stacked, a cool air passage is formed between the containers. As a result, ice as a refrigerant can be frozen much more quickly than a gel-type regenerator, and mass production and low cost of regenerative members can be easily realized.

[0010]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a rectangular container 1 having an open top and constituting a regenerative member according to the present invention. A flange portion 2 having a fixed width is integrally formed around the opening of the container 1. The container 1 is formed of a flexible plastic material such as propylene, for example, and contains water (or salt water) 3 inside the container 1 until, for example, the ninth minute.

The container 1 containing the water 3 is put into a freezer (not shown) and frozen at a high speed, and the water 3 is frozen to form ice 4 as shown in FIG. A sheet material 5 as a top seal material is placed on the flange portion 2 of the container 1 containing the ice 4 so as to cover the opening of the container 1 from the direction of arrow A in FIG. The peripheral portion of the sheet material 5 is bonded to the upper surface of the flange portion 2. Thereby, the inside of the container 1 is sealed by the sheet material 5 as shown in FIG. 4, so that ice and dissolved water do not leak out of the container 1. The means for bonding the sheet material 5 to the flange portion 2 of the container 1 may be a conventionally known means. For example, an adhesive and heat fusion can be exemplified. Note that the sheet material 5 may be a lid molded in advance.

Then, a plurality of the cold storage members 10 formed as described above are prepared, and as shown in FIG. 5, for example, instead of the ice 12 as shown in FIG. And fresh food such as squid is placed on it, covered with a lid 14 and packed and transported.

As a result, in a home or a supermarket receiving this, the fresh food is taken out of the transport case 1, the top seal of the remaining cool storage member is peeled off, the ice and the melted water inside are discarded, and the container 1 Recycle and reuse. The removed ice can be reused if necessary. Therefore, the generation of problematic industrial waste will be extremely reduced.

Further, if the cool storage member of the present invention is used, fresh foods such as squid do not come into direct contact with ice in the transport case, so that discoloration, deterioration and promotion of deterioration of freshness can be prevented. Unlike the conventional case, it is not necessary to provide a drainage hole when the ice melts in the transfer case, and the advantage that the cold storage continuity by shutting off the outside air can be maintained at a high level can be obtained. As a result, the thickness of the transport case can be reduced, and the overall weight can be reduced and the cost can be reduced.

The shape of the container 1 is not limited to the rectangular shape shown in the figure, but may be any shape. In particular, when the containers 1 are stacked, a cool air flow path is formed between the containers. The preferred shape is preferred. With such a shape, when the containers 1 containing the water 3 are stacked and frozen, the circulation of the cool air is improved and the freezing effect is improved, and when the containers 1 are used by being laid in the transport case 11. This is because the circulation of the cool air cooled by the cool storage member 10 is improved, and the cooling effect of the fresh food items stored in the transport case 11 is improved and uniform.

FIGS. 6 and 7 are perspective views showing an example of a container having a shape in which a cool air passage is formed between the containers when the containers are stacked. The container 1 shown in FIG. 6 has a curved portion 6a formed on the side wall 6. When the container 1 is stacked, the curved portion 6a serves as a flow path for cool air, and the cool air flows as indicated by arrows. The side wall 7 of the container 1 shown in FIG. 7 has a triangular shape, and when stacked, a gap is formed between the containers to form a cool air passage.

However, when the containers 1 containing the water 3 are stacked and frozen, the circulation of the cool air is improved and the freezing effect is improved. The circulation of the cool air cooled by the member 10 is improved, and the cooling effect of the fresh food stored in the transport case 11 is improved, and the cooling is uniform.

FIG. 8 is a cross-sectional explanatory view showing a manufacturing state of the cold storage member 10 according to the present invention, and FIG. 9 is a cross-sectional explanatory view showing a conventional cold storage agent manufacturing state. In FIG. 8, it can be understood that a gap 8 is formed between the containers 1, 1, and the cold air flows as shown by the arrows, so that the freezing effect is high and the cold storage member can be obtained in a short time. On the other hand, since the conventional regenerator 20 has a shape in which a gel-like regenerator is contained in a bag-shaped container, when stacked as shown in FIG. 9, there is almost no cold air passage when stacked. It is easy to understand that it takes a long time to freeze and is inefficient because it is in a state.

[0019]

[Effect of the invention]

 As described above, according to the present invention, the cold storage member has a configuration in which the water contained in the container is frozen to form ice, and the opening of the container is closed by the sheet material and sealed. In addition, fresh foodstuffs stored in the transport case with the cool storage member are stored stably for a relatively long time, and after the fresh foodstuffs are taken out of the transport case, the sheet material closing the opening is removed. By removing, it is possible to obtain the effect that the water in the container can be directly discharged and the remaining container can be recycled.

Further, according to the present invention, since the container and the sheet material are made of a flexible plastic, the fresh foodstuffs in the transport case do not come into direct contact with the ice, and thus are efficiently used. In addition to being able to cool this, the handling of the cold storage member can be facilitated. In addition, the unit price can be reduced as compared with the case where a gel-like regenerator is used, and the regenerator members can be manufactured quickly and in large quantities.

Further, according to the present invention, water is stored in a container, and after the water is frozen, a sheet material is brought into close contact with the periphery of the opening of the container so as to close the opening. Therefore, freezing of ice as a refrigerant can be performed much more quickly than that of a gel-type regenerator, and the effect of easily realizing mass production and low cost of regenerative members can be obtained.

Moreover, when the cool storage member according to the present invention is used for transporting fresh food products, it is possible to transport fresh food products while maintaining the quality of the fresh food products, and the melted ice water does not leak outside. It is convenient for transportation. In particular, when a cool storage member is laid in a transport case and fresh food is placed on it and transported, the drip generated from the fresh food flows down between the cool storage members and adheres to the fresh food to adhere to the fresh food. Therefore, quality can be maintained for a long time.

Further, according to the present invention, the containers have a shape in which a cool air passage is formed between the containers when the containers are stacked, so that the freezing effect is obtained when the containers are stacked and frozen. It can be manufactured in a short time, and the cooling effect is high and uniform when it is used in a transport case.

Furthermore, in the transportation of squid and the like, ice that has been finely crushed is used. However, since the ice has a large contact area with air, it is easy to melt and needs to be put in a large amount in a case. A lot of space was required for ice breaking. However, the regenerative member according to the present invention requires a long melting time and a small space. As a result, the thickness of the transport case can be reduced, the overall weight can be reduced, and the height of the case can be reduced, thereby achieving downsizing. As a result, the fare and the like can be significantly reduced.
