Description

Insulation Package Box {Insulation Package Box}

The present disclosure relates to a thermal insulation package box.

The content described in this section merely provides background information for the present disclosure and does not constitute the prior art.

Cold chain refers to a distribution network that controls temperature. Specifically, through the cold chain, the product can be distributed in a low temperature state from the production place to the destination, and through this, the freshness of the product can be maintained.

This cold chain has a more important meaning in the distribution of pharmaceuticals and medical products. Specifically, due to the characteristics of drugs and medical articles, safety, efficacy, stability, etc. need to be maintained at a certain level within the validity period. Accordingly, it is essential to manage the temperature in the distribution process of medicines and medical articles.

For example, pharmaceuticals should be distributed under refrigerated storage conditions, usually in the range of 2 to 8 °C. If the product is subjected to temperature changes outside of this temperature range during transportation, the drug may deteriorate. If altered medicine is applied to the human body, it can have a very fatal effect on the human body. In addition, it is difficult to distribute medical articles such as reagents and blood while maintaining an appropriate temperature.

According to the International Health Organization, about 25% of biopharmaceutical raw materials, clinical trial products, or biopharmaceuticals such as vaccines are discarded due to negligence in the transport process. As such, in all transport processes including long-term transport, the temperature of the article in the package box needs to be maintained within an appropriate range.

Accordingly, a main object of the present disclosure is to provide a thermal insulation package box capable of maintaining a refrigerated storage state at a level required for bio-logistics during long-term transportation.

According to an embodiment of the present disclosure, in a package box comprising a bottom plate, a plurality of side walls extending vertically from the bottom plate, and a lid disposed to face the bottom plate and configured to at least partially cover the plurality of side walls, the bottom It provides a thermal insulation package box, characterized in that at least one of the plate, the plurality of side walls, and the lid is a thermal insulation insulation surface including a vacuum insulation panel.

As described above, according to this embodiment, the present disclosure has an effect of providing a thermal insulation package box capable of properly maintaining the temperature of an article even during long-term transportation by stacking an extrusion method thermal insulation plate, a vacuum insulation panel, and the like.

1 is an exploded perspective view of a thermal insulation package box 10 according to an embodiment of the present disclosure.

2 is a side cross-sectional view of the thermal insulation package box 10 according to an embodiment of the present disclosure.

1 and 2 , the thermal insulation package box 10 is disposed to face the bottom plate 112 , a plurality of sidewalls 114 vertically extending from the bottom plate 112 , and the bottom plate 112 , and and a lid 116 configured to at least partially cover the plurality of sidewalls 114 .

The bottom plate 112 , the plurality of side walls 114 , and the lid 116 may generally form the outer shape of the thermal insulation package box 10 .

The bottom plate 112 , the plurality of side walls 114 , and the lid 116 may define an accommodation space S therein. The goods may be distributed in a state accommodated in the accommodation space (S).

The bottom plate 112 and the plurality of side walls 114 may be connected to each other. In a state in which the bottom plate 112 and the plurality of sidewalls 114 are connected, the lid 116 may be seated on the plurality of sidewalls 114 . Through this, the article can be seated in the accommodating space (S) or take out the article from the accommodating space (S).

However, the present disclosure is not limited thereto. For example, the lid 116 may also be connected to the plurality of sidewalls 114 . In this case, the lid 116 may include a plurality of lid segments (not shown) respectively connected to at least two sidewalls 114 . A plurality of lid fragments (not shown) may open and close the thermal insulation package box 10 by adjusting the folding with respect to the side wall 114 .

The connection between the bottom plate 112 and the plurality of side walls 114 may be made by adding an adhesive member or a separate member, but the present disclosure is not limited thereto. For example, the bottom plate 112 and the plurality of side walls 114 may be integrally formed.

At least one of the bottom plate 112 , the plurality of side walls 114 , and the lid 116 may be an insulating side 120 . Here, the thermal insulation insulating surface 120 refers to a surface having a thermal insulation function among the six surfaces constituting the outer shape of the package box 10 .

For efficient thermal insulation, all six surfaces of the package box 10 may be formed of an insulating insulating surface 120 . However, the present disclosure is not limited thereto, and at least one surface may be a common side (not shown) that does not include a heat insulating material.

The insulating insulating surface 120 may include a vacuum insulation panel (124), an inner extruded polystyrene (122), and an outer extruded polystyrene (126).

The inner extrusion method heating plate 122 may be disposed adjacent to the receiving space (S) on one surface of the vacuum insulation panel (124). In addition, the outer extrusion method thermal insulation plate 126 may be disposed spaced apart from the receiving space (S) on the other surface of the vacuum insulation panel (124).

The vacuum insulation panel 124 may be disposed between the inner extrusion method thermal insulation plate 122 and the outer extrusion method insulation plate 126 .

A vacuum insulation panel is an insulation panel that minimizes heat transfer by maintaining the inside of the panel in a vacuum state. In a vacuum state, heat transfer such as conduction or convection by air is not performed, so the vacuum insulation panel may have high thermal insulation properties.

Extruded polystyrene is an insulating material formed by dissolving a foaming agent at high temperature and high pressure and then extruding the solution through a mold.

Extrusion method thermal insulation plate has various compressive strength to withstand structural load, so it has high impact resistance. In addition, the extrusion method thermal insulation plate has a low thermal conductivity because it has a fine closed cell (closed cell) structure of the extrusion foaming method.

On the other hand, the thermal conductivity of the vacuum insulation panel is about 0.005W/mK, and the thermal conductivity of the extrusion method is about 0.036W/mK. That is, the vacuum insulation panel has better insulation performance than the extrusion method insulation plate. However, since the extrusion method is manufactured through the extrusion method, it has higher impact resistance than the vacuum insulation panel.

The thermal insulation package box 10 according to an embodiment of the present disclosure arranges high impact-resistance extrusion method insulation plates 122 and 126 in an area where an impact can be applied to the outside or inside, and between the extrusion method insulation There is a technical feature in arranging the vacuum insulation panel 124 with high thermal insulation performance. Accordingly, the thermal insulation package box 10 is strong in impact, and at the same time, it can have a more improved thermal insulation performance.

On the other hand, the vacuum insulation panel 124 in one heat insulating heat insulating surface 120 may be larger than the inner extrusion method thermal insulation plate 122 and smaller than the outer extrusion method insulation plate 126 .

Specifically, the central region of the outer extrusion heating plate 126 is covered by the vacuum insulation panel 124 , but the edge portion of the outer extrusion heating plate 126 may be exposed. In addition, the central region of the vacuum insulation panel 124 is covered by the inner extrusion method heating plate 122, but the edge portion of the vacuum insulation panel 124 may be exposed. Similarly, they may be stacked in a pyramid shape.

Through this, in the assembly process of the thermal insulation box 10, the interference between the inner extrusion method thermal insulation plate 122 adjacent to each other and the interference between the vacuum insulation panels 124 adjacent to each other can be minimized, and thus, the thermal insulation Assembly of the insulation box 10 can be made more easily.

Another embodiment of the present disclosure shown in FIGS. 3 and 4, which will be described later, differs from the embodiment of the present disclosure shown in FIGS. 1 and 2 in that the thermal insulation package box includes a bulkhead member and a latent heat material module. have Hereinafter, differential features according to other embodiments of the present disclosure will be mainly described, and repeated descriptions of components substantially the same as those of an embodiment of the present disclosure will be omitted.

3 is an exploded perspective view of the thermal insulation package box 20 according to another embodiment of the present disclosure.

4 is a top view of the thermal insulation package box 20 according to another embodiment of the present disclosure.

3 and 4 , the thermal insulation package box 20 may additionally include a partition member 230 and a latent heat material module 240 .

The partition member 230 may be disposed in the accommodating space S, and may divide the accommodating space S into at least two regions. For example, the accommodation space S may be divided into six spaces S1 to S6 by the partition member 230 .

However, the present disclosure is not limited thereto, and the partition member 230 may partition the accommodation space S in a number other than six according to its shape.

Since the partition member 230 divides the accommodating space S into two or more spaces, items to be accommodated in the thermal insulation package box 20 may be accommodated in an aligned state in the accommodating space S.

Meanwhile, at least a portion of the partition member 230 may be made of a metal material having high thermal conductivity. In this case, heat conduction through the partition member 230 may be performed between several items accommodated in the thermal insulation package box 20 .

Therefore, it is possible to minimize the temperature difference between the articles accommodated in the accommodation space (S), through which, more efficient insulation is possible.

The partition member 230 may be detachable with respect to the accommodation space (S). In this case, according to the number or size of the items accommodated in the thermal insulation package box 20 , a partition wall member 230 suitable therefor may be mounted in the accommodation space S.

However, the present disclosure is not limited thereto. For example, the partition member 230 may be integrally formed with at least one of the bottom plate 212 , the plurality of side walls 214 , and the lid 216 .

The latent heat material module 240 may include a latent heat material 242 and a latent heat material housing 244 accommodating the latent heat material 242 therein.

The latent heat material 242 is a phase change material, and may improve the thermal insulation performance of the thermal insulation package box 20 through a phase shift. Specifically, even if the latent heat material 242 takes heat away from the surroundings, the temperature of the latent heat material 242 does not change during phase change. Through this, the temperature gradient between the latent heat material 242 and the article can be minimized, and thus, the thermal insulation performance of the thermal insulation package box 20 can be effectively improved.

The latent heat material housing 244 may be made of a hard material such as plastic. Accordingly, as compared to a case in which the latent heat material 242 is contained in an envelope or a pack made of a paper material, the latent heat material module 240 may have high durability.

On the other hand, the partition member 230 may include at least one module mounting space 232 by way of example. In this case, the latent heat material module 240 may be disposed in the module mounting space 232 .

The latent heat material module 240 is disposed in the module mounting space 232 , and may be positioned at a predetermined place in the accommodation space S. Through this, there is an effect of constantly maintaining the flow of cold air due to the latent heat material 242 .

In addition, when the barrier rib member 230 is made of a metal material, heat conduction by the barrier rib member 230 in the accommodation space S may be smoothly performed. In this case, a uniform amount of heat is transmitted to each of the latent heat material modules 240 , so that the thermal insulation performance of the thermal insulation package box 20 may be improved.

However, the present disclosure is not limited thereto. For example, the latent heat material module 240 may be accommodated together with other articles in the accommodating space S without the partition member 230 .

3 and 4 , the latent heat material module 240 is illustrated as being accommodated in the accommodation space S in an upright state, but the present disclosure is not limited thereto. For example, the latent heat material module 240 may be accommodated in the accommodating space S in a state lying on its side.

Another embodiment of the present disclosure shown in FIG. 5, which will be described later, differs from the one embodiment of the present disclosure shown in FIGS. 1 and 2 in that the outer extrusion method thermal insulation plates of the insulating insulation surface are integrally formed. have Hereinafter, the differential features according to another embodiment of the present disclosure will be mainly described, and repeated descriptions of components substantially the same as those of an embodiment of the present disclosure will be omitted.

Referring to FIG. 5 , the bottom plate 312 and the plurality of sidewalls 314 are heat insulating insulating surfaces 320 , and the outer extrusion method heating plate 326 included in the bottom plate 312 and the plurality of sidewalls 314 . may be integrally formed.

By integrally forming the outer extrusion method thermal insulation plate 326 that forms the outer shape of the thermal insulation package box 30, compared with the case where the bottom plate 312 and the plurality of side walls 314 are composed of separate members, the thermal insulation package Assembly of the box 30 may be facilitated.

Specifically, without a separate process of bonding and fastening the bottom plate 312 and the plurality of side walls 314, by folding the outer extrusion method thermal insulation plate 326 formed integrally, the thermal insulation package box 30 can be easily assembled.

In addition, in the deployed state before use, since the entire thermal insulation package box 30 is made of one-piece or two-piece, the thermal insulation package box 30 can be transported more easily can

Meanwhile, in FIG. 5 , the inner extrusion method heating plates 322 and the vacuum insulation panel 324 are illustrated as being made separately from each other, but the present disclosure is not limited thereto.

For example, the inner extrusion method thermal insulation plates 322 and the vacuum insulation panels 324 may also be formed integrally, respectively. In this case, in the deployed state before use, the thermal insulation package box 30 may be composed of multiple layers. Accordingly, the transport of the thermal insulation package box 30 in the assembled or deployed state of the thermal insulation package box 30 can be made more easily.

The above description is merely illustrative of the technical idea of this embodiment, and various modifications and variations will be possible by those skilled in the art to which this embodiment belongs without departing from the essential characteristics of the present embodiment. Accordingly, the present embodiments are intended to explain rather than limit the technical spirit of the present embodiment, and the scope of the technical spirit of the present embodiment is not limited by these embodiments.
