More particularly, the present invention relates to a storage container assembly for refrigerated and frozen storage, The present invention relates to a storage container assembly for refrigeration and freezer storage, and a method of classifying a delivery object using the same.

Typically, a shipping box used in a distribution center includes a room temperature box that stores objects that can be stored at room temperature, and a low temperature box that stores objects that require low temperature maintenance.

The room temperature box generally uses a rectangular box. When the article is transported or loaded, the article is stored in the box and then the cover is covered to store or protect the object. On the other hand, the low-temperature box stores and keeps the freshness of the frozen food in an optimal state, and sometimes it can be carried and loaded for circulation sale. However, conventionally used room temperature boxes and low temperature boxes are not standardized, so it is difficult to use them in combination with room temperature boxes and low temperature boxes.

Especially, when it is desired to recover after using the room temperature box and the low temperature box, the room temperature box and the low temperature box can not be stacked and stacked at the same time. Since the room temperature box and the low temperature box are not standardized, the respective molds have to be separately manufactured in order to produce the room temperature box and the low temperature box according to various sizes. In addition, when the low-temperature box is inserted into the room-temperature box and mixed, the internal capacity is significantly reduced due to the low-temperature box thickness, resulting in a problem that only a small amount of articles can be stored or nested. If the low-temperature box is damaged, the entire low-temperature box has to be replaced, which causes the maintenance cost to increase.

This will be described later in more detail.

Although not shown in the figure, the body 410 of the low temperature box 400 includes a second lower surface 411 and a second lower surface 411 in the upward direction from the second lower surface 411, (Not shown) comprising a second front surface 412, a second rear surface 413, a second left surface 414 and a second right surface 415 which extend. The second storage space (unrepresented by the second surface 411, the second front surface 412, the second rear surface 413, the second left surface 414, and the second right surface 415) ).

The main body 410 is made of expanded polypropylene (EPP). The above-mentioned foamed polypropylene is spherical-shaped particles in which polypropylene which is a general-purpose plastic is foamed in physical (non-crosslinkable) without using a chemical foaming agent.

Polypropylene, which is a raw material of the foamed polypropylene, is excellent in cracking property, repetitive cushioning property, flexibility, chemical resistance and the like due to the characteristics of the resin, thereby improving the stability of product packaging and miniaturizing the packaging volume. It is lightweight, good in buffering property and excellent in rigidity, which is advantageous for weight reduction and excellent in heat resistance and heat insulation.

As described above, the low-temperature box 400 includes the partition 420 dividing the second storage space of the main body 410. As shown in FIG. 6, The second storage space (not shown) is divided while being inserted into the main body 410 along the height direction of the main body 410. Therefore, the first fixing groove 216 is formed in the main body 410 so that the partition 420 can be slidably inserted.

The first fixing groove 416 includes a first fixing groove 416a, a second fixing groove 416b, and a third fixing groove 416c. The second front surface 412, the second rear surface 413, the second left surface 414 and the second right surface 415 of the outer panel (unrepresented) of the main body part 410 are opposed to each other The first fixing groove 416a and the second fixing groove 416b are recessed inside the pair of side surfaces. The third fixing groove 416c is recessed inside the second bottom surface 411 of the main body 410.

More specifically, the first fixing groove 416a and the second fixing groove 416b are formed inwardly of the second front surface 412 and the second rear surface 413 and extend in the height direction. The second lower surface 411 is formed with a third fixing groove 416c that extends along the width direction and is concave. Particularly, the lower end of the first fixing groove 416a and the lower end of the second fixing groove 416b are connected by the third fixing groove 416c. Accordingly, the first fixing groove 416 is integrally formed with the first fixing groove 416a, the second fixing groove 416b, and the third fixing groove 416c.

Although the first fixing groove 416 includes the third fixing groove 416c in this embodiment, the third fixing groove 416c may be omitted. Since the first fixing groove 416 includes the third fixing groove 416c so that the partition wall 420 is also engaged with the third fixing groove 416c, Air is prevented from being convected by the partition wall 416 even if it is divided by the partition wall 416, so that airtightness can be maintained.

The partition wall 420 is formed in a plate shape having a rectangular cross section, as shown in FIG. However, the present invention is not limited to this embodiment, and thus it can be formed in various forms. The partition wall 420 is slid into the first fixing groove 416 to divide the second storage space (not illustrated).

The height direction of the barrier ribs 420 is longer than the height direction of the main body 410. A part of the partition wall 420 protrudes from the main body part 410 when the partition wall 420 is slid into the first fixing groove part 416 of the main body part 410.

This will be described in more detail in the description of the cover part 430. FIG.

Referring to FIGS. 7 and 8, the cover part 430 is formed in the shape of a plate having a rectangular cross-section. The cover 430 is formed with a protruding wall 430a projecting downward from a lower surface thereof. When the cover 430 is coupled to the main body 410, the protruding wall 430a protrudes from the first front surface 412, the second rear surface 413, And is formed with a left side face 414 and a mold groove 410a formed at the inner upper end of the first right side face 415. [ The cover 430 can be prevented from being easily separated from the main body 410 due to the combination of the protrusion wall 430a and the mold recess 410a.

The cover part 430 is formed with a refrigerant panel coupling part to provide the refrigerant panel 450. More specifically, a lower surface of the cover portion 430 is provided with a coolant coupling groove 431 formed concave at a predetermined depth in a direction toward the upper surface, And fixing protrusions 433 spaced apart from each other by a predetermined interval in the center of the side surface and protruding toward the inside of the refrigerant coupling groove 431.

The refrigerant panel 450 includes a housing 451 in which a phase change material (PCM) is filled in a rectangular parallelepiped shape and a pair of side walls 451 and 452 which are connected to one side of the housing 451, And a lid 453 that prevents the material from leaking. When the refrigerant panel 450 is coupled to the refrigerant panel coupling part of the cover part 430, at least one side surface of the longitudinal direction of the refrigerant panel 450 has a width of the refrigerant coupling groove 431 And the widthwise side surfaces of the refrigerant panel 450 are respectively in contact with the longitudinal side surfaces of the refrigerant coupling groove 431. [ At this time, the other side surface of the longitudinal direction of the refrigerant panel 450 is engaged with the fixing protrusion 433 to prevent the refrigerant panel 450 from being separated from the refrigerant panel connecting portion.

In the present embodiment, the fourth fixing groove 432a is formed between the fixing protrusions 433. The fourth fixing groove 432a and the fifth fixing groove 432b are connected by the sixth fixing groove 432c.

The sixth fixing groove 432c of the second fixing groove portion 432 may be omitted. The second fixing groove portion 432 includes the sixth fixing groove 432c so that the partition wall 420 is inserted into the sixth fixing groove 432c so that the low temperature box 400 May be kept airtight when divided by the partition 420. [

The protruding portion of the partition wall 420, which is slidably inserted into the body portion 410, is inserted into the second fixing groove portion 432 and coupled thereto. When the low temperature box 400 is divided by the partition 420, the low temperature box 400 may store an object requiring maintenance at a refrigeration temperature and an object requiring maintenance at a refrigeration temperature.

8, when the object requiring maintenance at the refrigeration temperature is stored in the low temperature box 400 together with the object required to be maintained at the refrigeration temperature, the cover part 430 is provided with two refrigerant panels 450 .

In the meantime, when only the object required to be maintained at the refrigeration temperature is stored in the low temperature box 400 or only the object requiring the maintenance at the refrigeration temperature is stored, the partition 420 is omitted, Only one is provided. 7, when the lid 453 of the refrigerant panel 450 is inserted between the fixing protrusions 433, the lid 435 is inserted into the fixing protrusion 433, (Not shown).

Referring to FIG. 9, the cover portion 430a includes a refrigerant panel coupling portion, which may include the refrigerant panel 450, like the cover portion 430 shown in FIGS. The coolant panel coupling portion includes a coolant supply groove 431 formed at a predetermined depth from the bottom surface of the cover portion 430a toward the upper surface and a mesh network 433a installed on a lower surface of the cover portion 430a.

In this embodiment, unlike the above-described embodiment, the refrigerant panel 450 is not fitted to the refrigerant-equipped groove 431. However, the net 433a provided on the lower surface of the cover part 430a is formed of an elastic material which is deformed when an external force is applied and is restored to an initial state when an external force is removed. Thereby preventing the refrigerant panel 450 from being separated from the refrigerant receiving groove 431a.

As described above, the net 433a is deformed when an external force is applied, and is restored to an initial state when the external force is removed. Thus, the net 433a is opened to open the coolant panel 450 to the coolant- Can be inserted. With this structure, the refrigerant panel 450 can be easily provided or the refrigerant panel 450 can be separated without applying a large force to the cover part 430a. In addition, if the mesh network 433a is damaged, only the mesh network 433a needs to be crossed. Thus, maintenance can be performed at a low cost.

The inside of the low temperature box 400 is divided by the partition wall 420 even if the object requiring maintenance at the refrigeration temperature and the object requiring maintenance at the refrigeration temperature are stored together in the low temperature box 400 as described above Therefore, it is possible to manage each internal temperature according to each object, and thus, each object can be kept fresh to the destination. Particularly, when the partition 420 is provided, the cover 430 is also coupled to prevent the air from being convected in the low temperature box 400.
