Description

Packaging method and packing box for transportation of refrigerated or frozen products

The present invention relates to a packaging method and a packaging box, and more particularly, to allow the internal temperature to be maintained for a relatively long time during product transportation, as well as to minimize the amount of refrigerant used, and to prevent transportation delays. The present invention relates to a packaging method and a packaging box for transportation of a refrigerated or frozen product.

As demand for frozen or refrigerated products through the online market increases, the transportation of goods using disposable iceboxes as disclosed in Korean Utility Model Publication No. 20-0407206 (published date: Jan. 25, 2006) is increasing.

Disposable ice box is the body and the cover is formed of a heat insulating material, so the internal temperature can be kept relatively constant during the transportation process, thereby minimizing the freshness of the product.

However, depending on extreme weather and the like, the transportation period may be longer, and even if the disposable ice box is used, the internal temperature is increased, thereby reducing the freshness of the refrigerated or frozen product.

In order to solve such a problem, the thickness of the main body and the cover of the disposable ice box is changed to a thicker thickness, or the main body and the cover material of the disposable ice box is changed to a material having better thermal insulation performance.

However, when increasing the thickness and the material of the body and the cover of the disposable ice box, the internal temperature maintaining effect in the transportation process slightly increased while the logistics cost significantly increased, there was a problem that the practical application is difficult.

For this reason, as shown in FIG. 9, injecting the refrigerated or frozen product and the refrigerant into the main body of the disposable ice box, coupling the cover to the main body of the disposable ice box, sealing the body between the main body and the cover of the disposable ice box. A packaging method for transporting a refrigerated or frozen product in order is used.

Such a conventional packaging method for transporting a refrigerated or frozen product may be maintained for a relatively long time in the transport process as compared with the general transport packaging method as the refrigerant is injected and the body and the lid are sealed.

However, in the conventional packaging method for transporting a refrigerated or frozen product, as the sealing proceeds after the refrigerant is added, the loss of the refrigerant occurs in the sealing process, for example, sublimation of dry ice (occurs below -73 to -76 ° C). There is a problem that the effect of maintaining the temperature is inevitably deteriorated, and the amount of refrigerant used must be increased.

In addition, the conventional packaging method for transportation of refrigerated or frozen products had to be carried out just before the transportation and sealing of the refrigerant in order to maximize the effect of maintaining the temperature, there was a problem that the transportation is delayed due to a considerable time in the sealing process. .

On the other hand, if the refrigerated or frozen product is pre-packaged before sale, the problem of delay in transportation can be solved, but the loss of the refrigerant is caused by the longer storage period, so that the effect of maintaining the temperature by the refrigerant is lowered. There was no choice but to increase the amount of refrigerant used.

For this reason, in the relevant field, the packaging method and packaging for transportation of refrigerated or frozen products, which not only allow the internal temperature to be maintained for a relatively long time during product transportation, but also minimize the amount of refrigerant used and prevent transportation delays. We are trying to develop a box, but have not been able to get satisfactory results until now.

The present invention has been proposed in view of the above circumstances, and when the conventional packaging method for transporting a refrigerated or frozen product is used, the refrigerant is lost in the sealing process as the sealing proceeds after the refrigerant is added, thereby maintaining the temperature by the refrigerant. It is an object of the present invention to provide a packaging method and a packaging box for transportation of refrigerated or frozen products to solve the problem that the effect is reduced and the problem that the refrigerant consumption is increased.

In addition, the present invention, when using a conventional packaging method for transporting refrigerated or frozen products, the refrigeration to solve the problem of delayed transportation due to the time required in the sealing process by performing the refrigerant input and sealing immediately before transportation Another object is to provide a packaging method and a packaging box for transportation of frozen products.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 1, the packaging method for transporting a refrigerated or frozen product according to the present invention, the step of adding the product (S1), the step of combining the cover (S2), sealing step (S3), the input of the refrigerant Step S4 and step S5 of joining the auxiliary cover.

In step S1 of injecting the product, the refrigerated or frozen product 100 is introduced into the main body 10.

At this time, the main body 10 is formed of styrofoam to have a heat insulating property.

Here, the styrofoam is formed by foaming the plastic, the plastic can be selected without limitation according to the use and function, and specifically may include at least one of polystyrene and polypropylene. In addition, the styrofoam may further include a material other than plastic, depending on the use.

On the other hand, the main body 10 includes a receiving space (not shown) on the inside, it is possible to insert the refrigerated or frozen product 100 into the main body 10 by the receiving space.

Joining the cover (S2) is coupled to the cover 20, the inlet 21 is formed in the main body 10.

In this case, the inlet 21 includes a binding groove 21a formed to be concave on the inner surface, so that the protrusion 31 of the auxiliary cover 30 to be described below is fixed to the binding groove 21a. The combined state of the 20 and the auxiliary cover 30 is maintained relatively firm.

In addition, the inlet 21 further includes a stepped portion 21b protruding from an inner surface, so that the bottom surface of the edge of the auxiliary cover 30 is caught on the top surface of the stepped portion 21b and the auxiliary cover 30 on the inlet 21. ) Is prevented from falling.

On the other hand, the cover 20 is formed of styrofoam in the same way as the main body 10 has a heat insulating property.

The sealing step S3 seals between the main body 10 and the cover 20.

In this case, the sealing means between the main body 10 and the cover 20 may be any kind of sealing material that can stably seal between the main body 10 and the cover 20. The furnace may be an adhesive tape.

In the step S4 of injecting the coolant, the coolant 200 is introduced into the main body 10 through the inlet 21.

In this case, the refrigerant 200 may use various kinds of ice pack, ice, dry ice, and the like.

However, since water generated while melting ice may contaminate the surroundings, it is preferable to use dry ice, which is sublimed into a gas at room temperature, as the refrigerant 200.

In step S5 of coupling the auxiliary cover, the auxiliary cover 30 is coupled to the inlet 21.

In this case, the auxiliary cover 30 includes the protrusion 31 coupled to the binding groove 21a, so that the protrusion 31 is coupled to the binding groove 21a, so that the auxiliary cover 30 is coupled to the cover 20. Is kept relatively robust.

Here, the protrusions 31 are formed to extend from the lower end to the upper end so that the cross-sectional area gradually increases, that is, the upper end of the protrusions 31 is formed to protrude outwardly from the lower end thereof, so that the protrusions 31 are formed in the binding groove ( As the binding to 21a), the cover 20 and the auxiliary cover 30 is more firmly coupled.

On the other hand, the auxiliary cover 30 is formed of styrofoam in the same manner as the main body 10 and the cover 20 has a heat insulating property.

In addition, as shown in FIG. 7 and FIG. 8, the packaging box A for transporting a refrigerated or frozen product according to the present invention includes a main body 10, a cover 20, and an auxiliary cover 30.

The body 10, the cover 20, and the auxiliary cover 30 have been described in detail above, and further description thereof will be omitted.

When described in detail with respect to the packaging for transporting the refrigerated or frozen product 100 using the packaging method for transporting a refrigerated or frozen product according to the present invention.

First, as shown in FIG. 2, the refrigerated or frozen product 100 is introduced into the main body 10.

At this time, since the main body 10 is formed of the styrofoam, the material has heat insulating properties, and thus, the freshness of the refrigerated or frozen product 100 introduced into the inner portion during the transportation process is maintained for a relatively long time.

Next, as shown in FIG. 3, the cover 20 in which the inlet 21 is formed is coupled to the main body 10.

As the cover 20 is coupled to the main body 10, the detachment of the refrigerated or frozen product 100 from the main body 10 is not only partially blocked, but also the inflow of outside air into the main body 10 is significant. Partly blocked.

In this case, since the cover 20 is formed of styrofoam, and has a heat insulating property due to its material property, as the cover 20 is coupled to the main body 10, the refrigerating or introduced into the main body 10 in the transportation process is performed. The freshness of the frozen product 100 is maintained for a relatively long time.

Next, as shown in Figure 4 is sealed between the main body 10 and the lid 20.

That is, a sealing means, for example, an adhesive tape is attached along the main body 10 and the cover 20.

Therefore, since the inflow of outside air between the main body 10 and the cover 20 is blocked, a decrease in thermal insulation effect due to the inflow of outside air through the main body 10 and the cover 20 is prevented.

Next, as shown in FIG. 5, the refrigerant 200, for example, dry ice, is introduced into the main body 10 through the inlet 21.

Since the inside of the main body 10 is maintained at a relatively low temperature state as the refrigerant 200 is introduced into the main body 10, the freshness of the refrigerated or frozen product 100 introduced into the main body 10 during the transportation process. Is maintained for a longer period of time.

On the other hand, after the sealing between the main body 10 and the cover 20, the refrigerant 200 is introduced into the main body 10, the refrigerant 200 can be stored for a longer period of time the main body in the transport process (10) Not only the internal temperature is maintained for a longer time, but also the loss of the refrigerant 200 in the sealing process is prevented so that the amount of the refrigerant 200 is minimized, and the time to transport can be shortened, thereby preventing transportation delays. .

Next, as shown in FIG. 6, the auxiliary cover 30 is coupled to the cover 20, more specifically, to the inlet 21.

Therefore, the inflow of outside air through the inlet 21 may be blocked, thereby preventing a decrease in thermal insulation effect due to inflow of the outside air through the inlet 21.

In this case, when the auxiliary cover 30 is inadvertently released from the inlet 21, outside air may be introduced through the inlet 21, and the heat insulation effect may be reduced.

However, in the present invention, the auxiliary cover 30 includes the protrusion 31 and the cover 20 includes the binding groove 21a, and the protrusion 31 is disposed in the binding groove 21a. As the auxiliary cover 30 is firmly coupled to the inlet 21 as it is bound, unintentional detachment of the auxiliary cover 30 from the inlet 21 is prevented. In addition, since the protrusion 31 is attached to the binding groove 21a, the auxiliary cover 30 cannot be detached without damaging the cover 20 or the auxiliary cover 30, and thus, before the final consumer reaches the final consumer. In the implementation process, the loss of contents or the insertion of foreign materials is impossible, thereby ensuring the safety of transportation for the end consumer.

On the other hand, the coupling of the auxiliary cover 30 is a relatively simple operation, since the operation of the auxiliary cover 30 is completed within a relatively short time, the transportation delay is prevented by carrying out the transportation immediately after the auxiliary cover 30 is coupled.

As described above, the packaging method and the packing box (A) for transporting a refrigerated or frozen product according to the present invention, before the refrigerant 200 is introduced into the main body 10 in which the refrigerated or frozen product 100 is accommodated. The sealing between the main body 10 and the cover 20 can be performed. As the refrigerant 200 is introduced immediately before transportation, the internal temperature of the main body 10 can be maintained for a relatively long time during the transportation process. In addition, the amount of the refrigerant 200 may be minimized, and transportation delays may be prevented as the transportation is performed immediately after the auxiliary cover 30 is coupled to the cover 20 after the refrigerant 200 is injected. Can be.

As described above, the present invention is not limited to the above-described embodiments, and may be changed within the scope not departing from the gist of the present invention as claimed in the claims, and such changes are defined by the following claims. It is within the protection scope of the invention.
