[0001] The present invention relates to a packaging box capable of maintaining a cold state, and more particularly to a packaging box capable of maintaining a cold state, It is possible to shorten the packaging time of the article by dividing the internal space of the space while maintaining the freshness of the article stored in the space portion of the storage unit during the transportation process and to easily inject and remove the refrigerant when necessary through the injection portion It is possible to recycle and use multi-purpose refrigerating unit, reduce the environmental pollution burden due to refrigerant disposal, and store the refrigerant in the storage unit by the main reinforcement tube and the first, second, third and fourth auxiliary reinforcement tubes As the unit is damaged, the refrigerant flows out to the outside of the storage unit to prevent the stored article from being contaminated or the article stored due to the deterioration of the cooling function It relates to a packaging box Cooler is available that can be.

Meat or fish or vegetables or fruits that require freshness preservation, refrigerated or frozen products (hereinafter referred to as "items requiring refrigeration") can easily be transformed during transportation or transportation, so they can be transported by refrigerator Precautions during transportation In order to keep the inside of the packaging box at a constant temperature while maintaining the environment and insulation, it is necessary to cool the inside of the packaging box.

Especially in recent years, due to the development of Internet commerce, TV home shopping, and courier industry, the transportation industry in which a small amount of refrigerated or frozen products are ordered through various routes in general households and the refrigerated or refrigerated products ordered are delivered by courier, .

However, it is practically impossible to transport a product requiring a small amount of cold storage to a general household by using a refrigerator or a cooling vehicle because the cost of selling the final product increases due to an increase in transportation costs.

In order to solve such a problem, a conventional packing box capable of inserting cold is used in which ice is filled in a space inside. However, when ice is melted in the transportation process, water inside the packing box is cooled, There has been a problem of lowering the commodity value of the commodity or inconveniencing the carrier.

Thereafter, by using the ice pack in a state in which a predetermined amount of the high-absorbent polymer material is used, instead of freezing, the article which needs to be refrigerated so that it does not overflow even if it dissolves is kept cold. However, A separate space is required, and as the package is packed up, the size of the packaging box increases, resulting in an increase in manufacturing cost.

In addition, since a conventional packaging box capable of cold storage can stack an ice pack on the upper or lower side of the article and then place a separate member inside the packaging box in order to separate articles requiring cold storage, Packaging of the packaging box of the present invention takes much time and requires a lot of manpower, resulting in an increase in the packaging cost and eventually an increase in the selling unit price.

Further, conventionally, a packaging box capable of keeping a cool condition using a simple ice pack has been problematic in that environmental contamination is increased as the ice pack is processed after delivery is completed.

In addition, since the ice pack is damaged or damaged during transportation, the packaging box that can be cold-stored using the conventional simple ice pack may damage the product itself due to leakage of the high absorption polymer charged inside the ice pack, There is a problem that the burden on the carrier is increased and the satisfaction of the final consumer is reduced as the product is corrupted.

The main body 310 forms an overall appearance of the refrigerating unit 300, and the refrigerant is stored in the main body 310. That is, the main body 310 is formed in the form of a double pack or the like so that the refrigerant can be stored therein. Such a refrigerant may be water, superabsorbent resin, ethylene glycol, a mixture of water and superabsorbent resin, or a mixture of water and ethylene glycol. Further, an auxiliary agent for increasing the viscosity may be added to the refrigerant.

The auxiliary agent does not increase the viscosity of the refrigerant and increases the viscosity of the refrigerant by activating the thickening effect at a low temperature so that the refrigerant in the refrigerating unit leaks out during transportation This is to prevent damage to stored goods.

In particular, when a certain force is applied to the main body portion by throwing a packing box in a transportation process or stacking other loads on the packaging box at a high level, the refrigerant leaks from a joint included in the structure of the main body or the cooling unit, Damage to the goods inside the box may occur. Therefore, by increasing the viscosity of the refrigerant through the auxiliary agent at a low temperature, the refrigerant can be prevented from leaking out even if the body portion is damaged.

Preferably, the adjuvant may include one or more compounds represented by the following formulas (1) to (4).

[Chemical Formula 1]

Wherein R is a linear or branched alkyl group having 1 to 10 carbon atoms or a benzyl group, R 'is a linear or branched alkyl group having 1 to 10 carbon atoms or a benzyl group, and n is an integer of 2 to 50)

(2)

Wherein R is a linear or branched alkyl or benzyl group having 1 to 10 carbon atoms, R 'is a linear or branched alkyl or benzyl group having 1 to 10 carbon atoms, R' 'is a linear or branched group having 1 to 10 carbon atoms, An alkyl group or a benzyl group, and n is an integer of 2 to 50)

(3)

Wherein R is a linear or branched alkyl or benzyl group having 1 to 10 carbon atoms, R 'is a linear or branched alkyl or benzyl group having 1 to 10 carbon atoms, R' 'is a linear or branched group having 1 to 10 carbon atoms, An alkyl group or a benzyl group, and n is an integer of 2 to 50)

[Chemical Formula 4]

Wherein R is a linear or branched alkyl or benzyl group having 1 to 10 carbon atoms, R 'is a linear or branched alkyl or benzyl group having 1 to 10 carbon atoms, R' 'is a linear or branched group having 1 to 10 carbon atoms, An alkyl group or a benzyl group, and n is an integer of 2 to 50)

When one or more of the compounds represented by formulas (1) to (4) is included as an auxiliary agent, not only the viscosity of the refrigerant in the low temperature process is increased but also the viscosity of the refrigerant is kept constant So that the internal refrigerant leaks out due to the breakage of the main body during the transportation, and the packed product may not be damaged.

Preferably, the adjuvant comprises at least one of the compounds represented by Formulas 1 to 4 and 0.1 to 2 parts by weight of retardant may be further added to 100 parts by weight of the adjuvant.

[ Experimental Example : Viscosity increase test]

When the refrigerant is injected into the refrigerant bag, the working efficiency according to the increase in viscosity is estimated to evaluate the refrigerant injection performance. The refrigerant injecting workability was evaluated based on the comparative example as the criterion (5), and the time spent in injecting the refrigerant in the range of 1 to 10 was evaluated and evaluated as an index. The higher the number, the better the workability.

Further, after the refrigerant bag into which the refrigerant was injected was frozen, the refrigerant bag was tested for the refrigerant stability by testing whether the refrigerant contained in the refrigerant leaked through the same size of the seam of the refrigerant bag. The stability of the refrigerant was evaluated as an index of 1 to 10 by evaluating the amount by which the refrigerant leaks when the same force is applied, using the comparative example as the criterion (5). The higher the number is, the more excellent the refrigerant does not leak out.

The above test results are repeated ten times, and the results are shown in Table 2 below as average values.

Comparative Example Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Example 7 Example 8 Inject refrigerant
Workability 5 3.2 2.1 3 One 3.4 5 5 5 Refrigerant stability 5 8.1 9.3 8 7 8 8.2 8.4 4.9

(Unit: index)

Referring to the above Table 2, it can be seen that the refrigerant stability is improved as a whole according to Examples 1 to 4. However, it can be seen that the workability is deteriorated in the process of injecting the refrigerant by the viscosity increase. Particularly, according to Examples 6 and 7, it was confirmed that the second sodium phosphate was contained so that the time for increasing the viscosity was delayed, the injection workability of the refrigerant was excellent, and the refrigerant stability was also excellent.

However, in the case of Example 5, there was no effect of retarding the time for increasing the viscosity, so that the effect of improving the workability of injecting refrigerant by using the dibasic sodium phosphate was not obtained. In addition, it was confirmed that the viscosity of Example 8 did not increase again, so that the refrigerant flowed well from the refrigerant bag and the stability of the refrigerant could not be improved.
