Description

Technical Field

[0001] The technical concept of the present disclosure relates to a packaging box, and more particularly, to a packaging box having flaps of different sizes formed therein so as to be packaged without using tape. Background Art

[0002] Typically, packaging boxes are made of paper, corrugated paper, laminated paper, or resin materials into a box shape to enclose contents, protect the interior from external impacts, and facilitate movement and storage of the contents.

[0003] Conventional packaging boxes have four vertical sides extending upward from the bottom, creating an internal space. This space, open to the top, is covered with a lid to store the contents. These boxes have a pair of flaps to prevent the contents from escaping, and the lid is secured with tape or adhesive to complete the packaging.

[0004] At this time, in order to prevent the contents from leaking during storage or transportation, the packaging box should be prevented as much as possible from opening the upper cover due to the load of the flap or the contents, and for this purpose, the packaging box should be packaged with strong tape or adhesive. Summary of the Invention

[0005] Problems to be solved by the invention

[0006] The technical concept of the present disclosure aims to provide a method for stably completing the packaging of a packaging box, instead of using a strong tape or adhesive made of a non-water-soluble synthetic resin or the like.

[0007] Means used to solve problems

[0008] According to an embodiment of the present disclosure, the packaging box is composed of multiple side walls and may include: a first wing panel extending from the first side wall among the side walls to cover the open upper part of the packaging box; a second wing panel extending from the second side wall located on the opposite side of the first side wall to form an area larger than the first wing panel; and an upper cover extending from the third side wall to cover the open upper part.

[0009] According to one embodiment, the second wing panel covers the first wing panel.

[0010] According to one embodiment, when the packaging box is packaged, the first area of ​​the upper cover is adhered to the second wing panel, and the second area that does not overlap with the first area is adhered to the fourth side wall opposite to the third side wall.

[0011] According to one embodiment, the upper cover includes: a pair of first section lines, which are arranged in the upper direction of the packaging box when the packaging box is in the packaging state; and a pair of second section lines, which are located at the upper part of the fourth side wall when the packaging box is in the packaging state, and distinguish a third area between the first area and the second area.

[0012] According to one embodiment, the adhesive is applied only to a portion of the first region based on any one of the pair of first section lines.

[0013] According to one embodiment, a distance between the pair of second section lines is 0.5 cm to 1 cm.

[0014] According to one embodiment, the upper cover and the second wing panel are spaced apart by a predetermined distance in a state of being deployed in a direction extending from the respective side walls.

[0015] Effects of the Invention

[0016] The packaging box according to the embodiments of the present disclosure provides a method for robustly and stably packaging a box without using strong adhesive materials that do not naturally decompose, such as non-water-soluble adhesives. Furthermore, the box can be easily disassembled by the user using the cut lines, and its volume can be easily reduced, thereby providing a method that improves user convenience.

[0017] The effects that can be obtained from the exemplary embodiments of the present disclosure are not limited to those mentioned above, and other effects not mentioned can be clearly derived and understood from the following description by those with ordinary knowledge in the technical field to which the exemplary embodiments of the present disclosure belong. In other words, effects other than those obtained by implementing the exemplary embodiments of the present disclosure can also be derived from the exemplary embodiments of the present disclosure by those with ordinary knowledge in the technical field to which the exemplary embodiments belong.

[0023] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0024] Figure 1 and Figure 2 is a diagram showing a packaging box 10 according to an embodiment of the present disclosure; Figure 3 2 is a diagram showing an embodiment in which the first wing panel 200 and the second wing panel 300 cover the upper portion of the box according to one embodiment; Figure 4 FIG. 1 is a diagram showing a package box 10 that has been completed according to an embodiment.

[0025] Reference Figure 1 The packaging box 10 may include a bottom portion blocking the bottom and four side walls extending from the bottom portion, as the four side walls may form an internal space. The packaging box 10 may include: a first wing panel 200 extending from a first side wall 410 of the four side walls; and a second wing panel 300 extending from a second side wall 420 on the opposite side of the first side wall 410.

[0026] According to one embodiment, the area of ​​the second wing panel 300 can be larger than that of the first wing panel 200. For example, the area of ​​the second wing panel 300 can be less than half of the cross-sectional area of ​​the interior space parallel to the bottom, while the area of ​​the first wing panel 200 can be more than half of the cross-sectional area of ​​the interior space parallel to the bottom. In this case, the sum of the areas of the first wing panel 200 and the second wing panel 300 can be greater than the cross-sectional area of ​​the interior space parallel to the bottom. Accordingly, when the first wing panel 200 and the second wing panel 300 are folded separately at the boundary of the sidewall, at least a portion of the first wing panel 200 and the second wing panel 300 can overlap.

[0027] The packaging box 10 may include an upper cover 100 extending from a third sidewall 430 that is separated from the first sidewall 410 and the second sidewall 420. An adhesive may be applied to the inner surface of the upper cover 100. According to one embodiment, the adhesive may be applied only to a portion of the upper cover 100. The upper cover 100 may have a plurality of section lines formed on the inner and outer surfaces of the upper cover 100.

[0028] Reference Figure 2The upper cover 100 may include a pair of first section lines 140 and a pair of second section lines 150. The pair of first section lines 140 may be section lines disposed toward the upper portion of the packaging box 10 when the packaging box 10 is in the packaged state, and the pair of second section lines 150 may be section lines that separate the fourth side wall 440 on the opposite side of the third side wall 430 from the upper space when the packaging box 10 is in the packaged state. For example, either of the pair of second section lines 150 may be connected to the end of the second wing panel 300 located below the upper cover 100.

[0029] When the packaging box 10 is in the packaged state, the pair of second section lines 150 form a shape that bends the upper cover 100 so that the upper cover 100 can contact the fourth side wall 440. More specifically, conventional packaging boxes 10 have a line-folded upper cover 100 that is folded once through a 90-degree fold between the side wall and the upper space. Even when folded, packaging boxes 10 made of thick cardboard require a strong force to unfold again, making it difficult to maintain a 90-degree fold for more than a predetermined period of time. To maintain the 90-degree fold of such cardboard, a strong adhesive or tape is required.

[0030] In contrast, in forming a 90-degree upper space and side wall, a pair of second sections 150 according to an embodiment of the present disclosure are such that each section folds the upper cover 100 45 degrees to contact the side wall and the second wing panel 300. Since it is folded 45 degrees, it can remain folded even without strong adhesion compared to the previous 90-degree folding.

[0031] In particular, according to the embodiments of the present disclosure, when the first wing panel 200 and the second wing panel 300 partially overlap, the thickness of the upper space is increased by the overlapping portion, thereby further increasing the upward force borne by the upper cover 100 compared to the conventional packaging box 10. In this regard, the upper cover 100 can form an excess space equivalent to the thickness of the upper space thickened by the pair of second section lines 150, thereby maintaining strong adhesion.

[0032] At the same time, any one of the pair of second section lines 150 is connected to the end of the second wing plate 300 located below the upper cover 100, and when disassembling the packaging box 10, the packaging box 10 can be easily disassembled by tearing off the pair of first section lines 140 and only tearing off any one of the pair of second section lines 150. Figures 5 to 7 A detailed description will be given later.

[0033] According to one embodiment, the spacing between a pair of second sections 150 can be determined by the thickness of the first wing 200 and the second wing 300. The size of the third area 130 determined by the second section 150 can be determined by the thickness of the upper space thickened by the wing. Conventional packaging boxes 10 are constructed with non-overlapping wing panels, and thus do not need to consider the thickness of the upper space thickened by the wing. In contrast, the packaging box 10 of the present disclosure is constructed with overlapping wing panels, and therefore needs to be stably adhered and fixed while considering the thickness of the thickened upper space.

[0034] However, when the third area 130 occupies too much space, when the upper cover 100 is bent along the second section line 150 , excessive space is formed between the second wing plate 300 , the fourth sidewall 440 and the upper cover 100 , and thus the upper cover 100 cannot be stably adhered.

[0035] Accordingly, the spacing between the second sections 150 of the present disclosure can be determined by the thickness and number of the wing panels. When the packaging box 10 is composed of two wing panels of cardboard material, the spacing between the second sections 150 can preferably be configured to be 0.5 cm to 1 cm.

[0036] The upper cover 100 can be divided into first, second, and third areas 110, 120, and 130. The first area 110 may be attached to the second wing panel 300 covering the upper space of the packaging box 10, and the second area 120 may be attached to the fourth sidewall 440 opposite the third sidewall 430. In this case, the third area 130 may be located in the space between the first and second areas 110, 120. The first, second, and third areas 110, 120, and 130 may be defined based on a pair of second section lines 150.

[0037] For example, in Figure 2 In the embodiment, the area in the -y direction starting from any one of the pair of second section lines 150 is the first area 110, which can be the area attached to the second wing panel 300. The area in the +y direction starting from the other of the pair of second section lines 150 is the second area 120, which can be the area attached to the fourth sidewall 440. The third area 130 can be the area in the +y direction for any one of the section lines and the area in the -y direction for the other section line.

[0038] According to one embodiment, the adhesive may be applied to the first to third areas 110 to 130 of the inner side surface of the upper cover 100. In this case, the adhesive may be applied to only a portion of the first area 110. For example, the adhesive may be applied to only a portion of the first area 110 based on the first section line 140. Figure 2In this embodiment, adhesive can be applied in the +y direction, based on the section line in the +y direction of the pair of first section lines 140, while adhesive can be omitted in the -y direction. In other words, adhesive does not adhere to the space between the pair of first section lines 140. Therefore, when a user cuts through the first section lines 140, they can tear off the unapplied adhesive area, allowing the packaging box 10 to be disassembled with minimal force.

[0039] according to Figure 3 The packaging box 10 is such that the first wing panel 200 can be folded toward the upper space, and the second wing panel 300 can be folded toward the upper portion of the first wing panel 200 .

[0040] The upper cover 100 can be folded toward the second wing 300, and the adhesive applied to the inner surface of the upper cover 100 can be attached to the fourth side wall 440 of the packaging box 10. At this time, the second wing 300 can be kept horizontal with respect to the bottom surface through the upper cover 100, and can also fix the first wing 200 to prevent it from popping up.

[0041] At the same time, a portion of the inner side surface of the upper cover 100 is attached to the second wing plate 300 , so that the angle between the fourth side wall 440 and the second wing plate 300 corresponds to the bending angle of the upper cover 100 .

[0042] Figure 4 FIG. 1 is a diagram showing a package box 10 that has been completed according to an embodiment.

[0043] Reference Figure 4 When the packaging box 10 is packaged, the upper cover 100 is attached to a portion of the second wing panel 300 and the fourth side wall 440, thereby preventing the package from being opened due to the first wing panel 200, the second wing panel 300 and the items inside the box.

[0044] The pair of second section lines 150 configured on the upper cover 100 can be located above the fourth sidewall 440. However, the embodiments of the present disclosure are not limited thereto, and the second section lines 150 can be located around the boundary between the fourth sidewall 440 and the upper space, including the edge of the upper space. For example, either of the pair of second section lines 150 can be located above the fourth sidewall 440, and the other of the second section lines 150 can also be located in the upper space.

[0045] Figures 5 to 7 FIG. 1 is a diagram illustrating an embodiment of disassembling a package box 10 along a cross-section line of the package according to an embodiment.

[0046] Reference Figure 5When the user disassembles the package box 10, the pair of first section lines 140 can be cut. A semicircular groove can be formed between the pair of first section lines 140. The user can grasp the semicircular groove to tear the first section lines 140. A semicircular groove can also be formed on one side of the upper cover 100, but the position and number of the grooves are not limited thereto.

[0047] Reference Figure 6 If the area between the pair of first section lines 140 is removed from the upper cover 100, the uncoated area based on the first section lines 140 can be opened, but the remaining uncoated area cannot be opened. In other words, even if the first section lines 140 are cut, the first wing panel 200 and the second wing panel 300 remain horizontal relative to the bottom surface, and the internal space cannot be opened.

[0048] Reference Figure 7 , either of the pair of second sections 150 can be cut, thereby opening the second flap 300 in an upward direction. In this case, the cut second section 150 can be the section that connects to the end of the second flap 300. When the first flap 200 and the second flap 300 are opened, the interior space is exposed, allowing the user to remove items inside.

[0049] Reference Figures 5 to 7 The user can easily disassemble the packaging box without tape by only two cutting actions, and the cutting line for guiding the cutting action is marked on the outside of the box, so the user can easily understand the disassembly method of the packaging box 10.

[0050] Figure 8 FIG. 1 is a diagram illustrating an embodiment in which the second wing panel 300 is spaced apart from the upper cover 100 by a predetermined interval according to an embodiment.

[0051] Reference Figure 8 When the upper cover 100 and the second wing panel 300 are erected upward, a predetermined distance may be spaced between the upper cover 100 and the second wing panel 300. The package box 10 of the present disclosure may be formed by folding the first wing panel 200 and the second wing panel 300 in an overlapping manner, thereby forming a thicker upper space than the conventional package box 10.

[0052] In this case, when the second wing panel 300 is not spaced apart from the upper cover 100 by a predetermined distance, the thickness of the upper space can increase the upward force on the upper cover 100. Accordingly, the package box 10 of the present disclosure can be configured to space the first wing panel 200 and the second wing panel 300 apart from the upper cover 100 by a predetermined distance, thereby minimizing the force on the upper cover 100 due to its thickness.

[0053] At the same time, the positions of the pair of first section lines 140 can be determined by the predetermined distance between the upper cover 100 and the second wing plate 300. Specifically, any one of the first section lines 140 can be connected to the end of the second wing plate 300. Figure 2 , the first section line 140 located in the −y direction among the pair of first section lines 140 may be connected to the end of the second wing plate 300 .

[0054] Thus, the packaging box 10 is bent once at the boundary between the third side wall 430 and the upper cover 100, and then bent again at any one of the first section lines 140. These two bends maintain a 90-degree curve between the third side wall 430 and the upper cover 100. At this point, when the upper cover 100 is bent at the first section line 140, the first wing panel 200 and the second wing panel 300 naturally bend, allowing the upper cover 100 to be reattached to the first wing panel 200 and the second wing panel 300 while maintaining a horizontal position.

[0055] As described above, exemplary embodiments are disclosed in the drawings and the specification. Specific terms are used in this specification to describe the embodiments, but this is only for the purpose of illustrating the technical concept of the present disclosure and is not intended to limit the meaning or the scope of the present disclosure as described in the claims.
