1 and 2 , the packaging box 1000 may include a body part 100 and a cover part 150 .

The main body 100 may be formed of the front and rear surfaces of the packaging box 1000 . The main body part 100 is composed of the front part 120 and the front part 120, the side part 130 that covers the left and right sides, and the bottom part 140 that covers and closes the lower part of the front part 120 and the side part 130. , respectively connected to the front and rear surfaces of the body unit 100 and located on the upper surface to seal the inside of the body unit 100, the cover unit 150 having a handle 151 that is extended and coupled to the upper side 150, the front unit 120, and The side portion 130 may have an insertion hole 101 formed in a direction parallel to the bottom surface. Through this, the structure of the packaging box 1000 can connect a plurality of packaging boxes 1000, so that the contents can be transported more conveniently.

The front part 120 is folded toward the cover part 150 while discharging the moisture generated inside the body part 100 to the outside, and the insertion hole of the adjacent packaging box 1000 located above the cover part 150 . It may include a front fastening part 161 that is fastened to the 101 . For example, the front fastening part 161 may be folded in the vertical direction to the upper surface around the corner where the upper surface and the side surface of the main body part 100 meet, and the front fastening part 161 folded once is folded once more. can Through this, the packaging box 1000 is connected in plurality, so that the contents can be transported more conveniently.

The side portion 130 may include a side fastening portion 162 that is fastened to the insertion hole 101 of the adjacent packaging box 1000 positioned on the upper portion of the cover portion 150 or fixing the handle 151 . Accordingly, the side fastening portion 162 is fastened with the insertion hole 101 of the other packaging box 1000 to give a supporting force to the connection of the plurality of packaging boxes 1000, so that the connection of the plurality of packaging boxes 1000 is can be made more robust.

The insertion hole 101 includes a front insertion hole 121 formed adjacent to the bottom surface 140 in the front portion 120 , and a front insertion hole 121 formed adjacent to the bottom surface 140 in the side portion 130 . ) may include a side insertion hole 131 formed longer than. For example, the insertion hole 101 is formed at the lower end of both side surfaces of the body portion 100, and may include a through portion formed in a cross-sectional shape of the fastening portion 160 . Accordingly, the insertion hole 101 is fastened with the fastening part 160 of the other packaging box 1000 to connect the plurality of packaging boxes 1000 in the vertical direction, thereby making it more convenient to transport a plurality of products. .

The cover part 150 and the side part 130 may include an air circulation part 110 for discharging moisture generated inside the body part 100 to the outside. For example, the air circulation unit 110 may be formed on two surfaces of the body portion 100, and may have three base structures on one surface. Through this, the user can control the moisture inside the packaging box 1000 by folding and unfolding the base structure of the air circulation unit 110 when the packaging box 1000 is transported.

A cup fixing part 153 may be formed in the cover part 150 . For example, it may be formed in a circular support structure so that a bottle, a can, and a cup can be inserted into the cup fixing part 153 . Through this, it is possible to transport bottles, cans, glasses, etc. as well as contents to the packaging box 1000 . In addition, since the cup fixing part 153 formed in a circular support structure can be folded and used, it can be accommodated even if the size of the cup is changed, and the user does not have to worry about dropping the cup while carrying it due to the high fixing force.

The handle 151 may further include a folding protrusion 151a formed inside to allow the user's hand to enter and exit. The folding protrusion 151a may be formed on the inner upper end of the handle 151 and protrude downward. For example, the folding protrusion 151a may be formed on one side of the inner upper end of the handle 151 and protrude downward. Through this, the folding protrusion 151a is folded in the other direction of the inner upper end of the handle 151, and the folding protrusion 151a wraps around the lower portion of the inner upper end of the handle 151 and is folded so as to be in close contact with the side of the handle 151. As a result, the folding protrusion 151a fixes the handle 151 so that it is not unfolded, so that the product packaging of the packaging box 1000 can be made more robust.

The locking projections 152 may be formed on the upper ends of both sides of the cover unit 150 to fix the handle 151 . For example, the locking protrusion 152 may be formed as a rectangular protrusion on both sides of the handle 151 . Through this, the locking protrusion 152 is fastened with the penetrating portion of the upper surface of the side portion 130, so that the connection of the handle 151 is released and the upper surface of the main body 100 is unfolded, so that there is no concern about the contents leaking out.

이상의 넓이를 가질 수 있다. 이를 통해, 어느정도 부피를 차지하는 내용물의 경우에도 포장박스(1000)를 이용해 보다 손쉽게 운반할 수 있다.The packaging box 1000 may be formed in a structure to facilitate interpolation of the product. For example, in order to transport a lunch box, the area of the bottom 140 of the packaging box 1000 is about 40000.

may have more than one width. Through this, even the contents occupying a certain volume can be more easily transported using the packaging box 1000 .

The body part 100 may include a separation part 170 . For example, the separation unit 170 having a base structure is formed on the lower surface of the main body 100 so that the separation unit 170 can be folded and unfolded. Through this, the separation unit 170 serves to separate the inner surface of the packaging box 1000 , and may be suitable for separating and loading different products in the packaging box 1000 .

The packaging box 1000 is formed with a curved line. For example, the packaging box 1000 has a structure that can be easily folded using a bending line. Through this, the packaging box 1000 can be quickly and accurately folded, and the unfolded packaging box 1000 can be stacked layer by layer for easy storage.

3 is a perspective view illustrating a use state of a packaging box including a coupling structure according to an embodiment of the present invention.

Referring to FIG. 3 , a plurality of packaging boxes 1000 are vertically coupled and connected. For example, the three packaging boxes 1000 may be coupled by connecting the insertion hole 101 and the fastening unit 160 . Through this, the connection of the plurality of packaging boxes 1000 may be further strengthened.

4 is a perspective view of a packaging box including a coupling structure according to an embodiment of the present invention.

Referring to FIG. 4 , the packaging box 1000 can be folded with one touch. For example, the packaging box 1000 can be made by one interaction like a conventional two-pronged cup carrier due to the structure of the lower surface. Through this, the process of folding or assembling is partially omitted, so that the transport of the contents can be more convenient.

5 is a cut-away perspective view of a packaging box including a coupling structure according to an embodiment of the present invention.

Referring to FIG. 5 , a support part 200 capable of forming an air layer may be formed on the inner surface of the body part 100 . For example, the support 200 may be a corrugated cardboard formed to be spaced apart from the front part 120 and the side part 130 by a predetermined distance so that an air layer of 3 mm can be formed on the inner and outer shell of the body part 100 . Through this, the support 200 is formed in the form of an air cap effective to maintain the temperature by forming an air layer, so that the heat preservation and cooling effect of the contents can be more excellent.

The support part 200 may be made of a material having an excellent effect in maintaining the temperature of the product. For example, the support unit 200 is spaced apart from the front portion 120 and the side portion 130 by a predetermined distance so that an air layer of 6 mm can be formed on the inner and outer shell of the body portion 100. . Through this, the packaging box 1000 may be more excellent in thermal insulation and cooling effect of the product.

On the other hand, the following tables relate to the temperature change test of the packaging box according to the present invention.
