Description

packaging box

[0001] The present disclosure relates to a packaging box.

[0002] Conventionally, a package box containing an item such as a medicine, a quasi-drug, a medical device, or a cosmetic product has been enclosed with a document containing an explanation of the item (see, for example, Patent Document 1). The explanation of the item may also be displayed on the package box. For example, a package box 110 shown in FIGS. 7 and 8 (see, for example, Patent Document 2) has a lid 111 that forms a part of the top surface, which opens to form an opening 112 through which the item contained therein can be removed. In this package box 110, an explanation 113 of the item is displayed on the inner surface of the open lid 111, as shown in FIG. 8.

[0003] JP 2012-012026 A JP 2007-126194 A

[0004] However, creating a document containing an explanation of the product and enclosing it in the packaging box increases the manufacturing cost and complicates the manufacturing process.

[0005] 8, when an explanation 113 about the product is displayed on the inner surface of the lid 111 of the packaging box 110, the display area of ​​the lid 111 is limited, making it impossible to adequately display the explanation 113 about the product. Furthermore, if the product moves or rattles inside the packaging box 110 during transportation, etc., and the inner surface of the lid 111 is rubbed by the product, the explanation may disappear or become difficult to see due to friction.

[0006] The present disclosure focuses on the above-mentioned problem and aims to provide a packaging box that can display a description of an item without the need to separately prepare a document containing a description of the item, and in which the display of the description of the item is not easily affected by the item contained inside.

[0021] The packaging box of the present disclosure is for storing and transporting and displaying articles such as medicines, quasi-drugs, medical devices, cosmetics, etc. Hereinafter, one embodiment of the packaging box of the present disclosure will be described with reference to the accompanying drawings.

[0022] <Overall Configuration of Packaging Box> As shown in Figures 1 to 4, the packaging box 100 includes a box body 1 capable of accommodating articles, and a header 10 protruding from the box body 1. In the present disclosure, the direction in which the header 10 protrudes from the box body 1 is defined as the upward direction. That is, the diagonally upper right direction in Figure 1(A) is defined as the upward direction, and the opposite diagonally lower left direction is defined as the downward direction. Furthermore, the direction perpendicular to the main surface of the header 10 is defined as the front-to-rear direction. That is, the diagonally upper left direction in Figure 1(A) is defined as the forward direction, and the opposite diagonally lower right direction is defined as the rearward direction. Furthermore, the direction perpendicular to the up-down direction and the front-to-rear direction is defined as the left-to-right direction. That is, the upward direction in Figure 1(A) is defined as the rightward direction, and the opposite downward direction is defined as the leftward direction.

[0023] The box body 1 has a hexahedral shape, for example, and in this embodiment, a rectangular parallelepiped shape. The box body 1 includes a cylindrical body 2 and a pair of closing members 3 that close openings at both ends of the body 2 in the axial direction extending left and right. The body 2 has a rectangular cylindrical shape with a cross section perpendicular to the axial direction that is rectangular, and has a front surface on the front side, a back surface on the rear side opposite the front surface, an upper top surface perpendicular to the front and back surfaces, and a lower bottom surface perpendicular to the front and back surfaces and opposite the top surface. A header 10 extends upward from the box body 1 on the back side of the body 2.

[0024] The header 10 has small holes formed therein for hanging the packaging box 1 from a hook when exhibiting or displaying, and is a portion on which information regarding the items to be stored in the packaging box 1, particularly information for promoting or advertising the items, is displayed. The header 10 comprises a first header piece 11 and a second header piece 12 that overlap each other. The first header piece 11 and the second header piece 12 are thin plates, and the strength of the header 10 is increased by the overlapping of the first header piece 11 and the second header piece 12.

[0025] The first header piece 11 is connected to the upper side of the first side wall 20 that forms the back surface of the body 2. The first header piece 11 and the first side wall 20 are made of the same single plate material, with the lower part of the plate material forming the first side wall 20 and the upper part of the plate material forming the first header piece 11.

[0026] A pair of left and right first break lines 4 is formed in the first side wall 20 of the body 2. A pair of left and right second break lines 5 is formed in the second side wall 21 that constitutes the bottom surface of the body 2. The second side wall 21 is connected to the lower edge of the first side wall 20 and is generally perpendicular to the first side wall 20. The second break lines 5 are continuously connected to the first break lines 4. The portion of the second side wall 21 between the pair of left and right second break lines 5 is an opening start portion 26. The portion of the first side wall 20 between the pair of left and right first break lines 4 is a lid portion 25. When the opening start portion 26 is peeled along the pair of left and right second break lines 5 and separated from the rest of the second side wall 21, the lid portion 25 becomes openable. When the lid portion 25 is peeled along the pair of left and right first break lines 4 and separated from the rest of the first side wall 20, the lid portion 25 opens, forming an opening 27 in the box body 1 that allows the contents to be removed, as shown in FIG. 4 . This allows the article to be taken out from inside the box body 1.

[0027] Next, the box body 1 and the header 10 that constitute the packaging box 100 of this embodiment, and the blank sheet 101 (shown in FIG. 6) for forming the packaging box 100 will be described in detail.

[0028] <Box Body> As shown in Figures 1 to 4, the trunk 2 of the box body 1 includes a first side wall 20 constituting the back surface, a second side wall 21 constituting the bottom surface, a third side wall 22 constituting the top surface, a fourth side wall 23 constituting the front surface, and a fifth side wall 24 constituting the bottom surface. Each side wall 20-24 is thin and rectangular, and in this embodiment, each side wall 20-23 is rectangular, while the fifth side wall 24 is trapezoidal. The first side wall 20 and the fourth side wall 23 are approximately the same size. The second side wall 21 and the third side wall 22 are approximately the same size. The fifth side wall 24 is smaller in size than the second side wall 21.

[0029] The second side wall 21 is connected to the lower edge of the first side wall 20. The third side wall 22 faces the second side wall 21. The fourth side wall 23 faces the first side wall 20. The third side wall 22 is connected to the upper edge of the fourth side wall 23, and the third side wall 22 is generally perpendicular to the fourth side wall 23. The fifth side wall 24 is connected to the lower edge of the fourth side wall 23, and is generally perpendicular to the fourth side wall 23. The fifth side wall 24 is overlapped on the inside of the second side wall 21, and at least a portion of the second side wall 21 is fixed to the outer surface of the fifth side wall 24 using an adhesive, a pressure-sensitive adhesive, double-sided tape, or the like. Note that, in each side wall 20-24, the inside refers to the side facing the internal space of the box body 1, and the outside refers to the opposite side.

[0030] A cut line 28A is formed in the center position of the second side wall 21 in the left-right direction, and curves convexly toward the rear edge of the second side wall 21. The cut line 28A penetrates the second side wall 21 in the thickness direction, and an insertion piece 29 is formed in the area surrounded by the cut line 28A.

[0031] A cut line 28B extending in the left-right direction is formed in the center of the fifth side wall 24. The cut line 28B penetrates the fifth side wall 24 in the thickness direction and defines an insertion hole into which the insertion piece 29 can be inserted.

[0032] The pair of closures 3 of the box body 1 are located at both ends of the trunk 2 in the left-right direction and form the left and right side surfaces of the box body 1. Each closure 3 includes a first flap 30, a second flap 31, a third flap 32, and a fourth flap 33. Each of the flaps 30-33 is thin and generally rectangular. The thickness of each of the flaps 30-33 is generally the same as the thickness of each of the side walls 20-24 of the trunk 2.

[0033] The first flap 30 is connected to the left and right side edges of the third side wall 22 of the body 2 and is generally perpendicular to the third side wall 22. The second flap 31 is connected to the left and right side edges of the second side wall 21 of the body 2 and is generally perpendicular to the second side wall 21. The first flap 30 and the second flap 31 are generally the same size. The front-to-rear length of the first flap 30 and the second flaps 31 is shorter than the front-to-rear length of the second side wall 21 and the third side wall 22 (the depth of the body 2). The up-to-down length of the first flap 30 and the second flaps 31 is approximately half the up-to-down length of the fourth side wall 23 (the height of the body 2), and the tip of the first flap 30 and the tip of the second flap 31 face each other with a gap between them.

[0034] The third flap 32 is connected to the left and right side edges of the fourth side wall 23 of the body 2 and is generally perpendicular to the fourth side wall 23. The fourth flap 33 is connected to the left and right side edges of the first side wall 20 of the body 2 and is generally perpendicular to the first side wall 20. The vertical length of the third flap 32 is smaller than the vertical length of the fourth side wall 23 (the height of the body 2). The front-to-rear length of the third flap 32 is shorter than the front-to-rear lengths of the second side wall 21 and the third side wall 22 (the depth of the body 2). The size of the fourth flap 33 is larger than the size of the third flap 32. The vertical length of the fourth flap 33 is approximately the same as the vertical length of the fourth side wall 23 (the height of the body 2). The front-to-rear length of the fourth flap 33 is approximately the same as the front-to-rear length of the second side wall 21 and the third side wall 22 (the depth of the body 2).

[0035] A third flap 32 is superimposed on the outside of the first flap 30 and the second flap 31, and a fourth flap 33 is superimposed on the outside of the third flap 32. At least a portion of the fourth flap 33 is fixed to the third flap 32 using an adhesive, a pressure-sensitive adhesive, double-sided tape, or the like, thereby closing the openings at both left and right ends of the body 2.

[0036] In this embodiment, the closure portion 3 is composed of four flaps 30-33, but there is no particular limitation on the configuration of the closure portion 3. As long as both ends of the body portion 2 can be closed, the number and shape of the flaps are not particularly limited.

[0037] 1 to 4, each header piece 11, 12 of the header 10 is a thin plate having a rectangular shape, and in this embodiment, a rectangular shape. The first header piece 11 and the second header piece 12 are approximately the same size. The thickness of each header piece 11, 12 is approximately the same as the thickness of each side wall 20-24 of the body portion 2.

[0038] The first header piece 11 extends above the first side wall 20 of the body 2. In other words, the first header piece 11 is flush with and continuous above the first side wall 20 so that the first side wall 20 extends upward, and the first side wall 20 and the first header piece 11 are aligned in a continuous manner so that their outer surfaces and inner surfaces are flush with each other. Therefore, in this embodiment, there is no clear boundary between the first side wall 20 and the first header piece 11, and the space between them is flat without any steps or irregularities. Note that a fold or break line may be provided between the first side wall 20 and the first header piece 11, or the first header piece 11 may be continuous above the first side wall 20 so that there is a clear boundary between them.

[0039] The left-right length of the first header piece 11 is approximately the same as the left-right length of the first side wall 20. Note that the left-right length of the first header piece 11 may become narrower or wider, for example, as it extends upward.

[0040] The second header piece 12 is connected to the upper edge of the first header piece 11. The second header piece 12 is folded back at the upper edge of the first header piece 11 relative to the first header piece 11, thereby overlapping the first header piece 11. The second header piece 12 is simply overlapped on the first header piece 11, and in this embodiment, it is not fixed to the inner surface of the first header piece 11 using adhesive, pressure-sensitive adhesive, double-sided tape, or the like.

[0041] The third side wall 22 of the body 2 is connected to the lower edge of the second header piece 12, and the second header piece 12 is generally perpendicular to the third side wall 22.

[0042] 1, 2, and 4, a pair of left and right first break lines 4 are formed in the first side wall 20 of the body 2 and the first header piece 11 of the header 10. The first break lines 4 are lines that break when an external force is applied. The first break lines 4 can be configured as, for example, perforations or half-cut lines, and in this embodiment, they are configured as perforations.

[0043] The pair of left and right first break lines 4 extend linearly in the up-down direction so as to be generally parallel to each other with a gap between them in the left-right direction, and reach from the lower edge of the first side wall 20 to the upper edge of the first header piece 11. This allows the lid portion 25 between the pair of left and right first break lines 4 in the first side wall 20 and the separation portion 13 between the pair of left and right first break lines 4 in the first header piece 11 to be peeled off together.

[0044] 4, when the lid portion 25 is separated from the other portions of the first side wall 20 along the pair of left and right first break lines 4, the lid portion 25 opens to form an opening 27, and items stored in the box body 1 can be removed through the opening 27. Furthermore, when the separation portion 13 is separated from the other portions of the first header piece 11 along the pair of left and right first break lines 4, the separation portion 13 separates from the second header piece 12, and the inner surface of the separation portion 13 can be exposed.

[0045] As shown in Figures 1 and 2, the perforations that make up the first break line 4 are formed by arranging multiple notches 40 at intervals in the direction in which the first break line 4 extends. Each notch 40 of the perforations may be dotted or linear, and in this embodiment, it is linear. Furthermore, each notch 40 of the perforations may be linear or may have various shapes, such as a V-shape with one end bent or an arrow shape with one end widening into a V-shape. In this embodiment, each notch 40 of the perforations is V-shaped.

[0046] Each dogleg-shaped notch 40 has a first portion 41 extending in the direction of the first break line 4 and a second portion 42 bending from the first portion 41. The first portions 41 of each notch 40 are aligned in a straight line. The second portions 42 of each notch 40 may bend to either the left or right of the direction of the first break line 4, but in this embodiment, they are bent toward the left and right side edges of the first side wall 20 and the first header piece 11. In other words, the left first break line 4 is bent toward the left side edge of the first side wall 20 and the left side edge of the first header piece 11, and the right first break line 4 is bent toward the right side edge of the first side wall 20 and the right side edge of the first header piece 11.

[0047] As a result, as shown in Fig. 4 , multiple thorn-like protrusions 14 are formed on the lid portion 25 and the separation portion 13 of the first header piece 11 when the lid portion 25 of the first side wall 20 and the separation portion 13 of the first header piece 11 are peeled away. If the second portion 42 of each notch 40 is bent in the opposite direction to that of this embodiment, that is, in the case of the conventional packaging box 110 shown in Fig. 8 , the multiple thorn-like protrusions 114 remain on the left and right edge sides of the opening 112. Therefore, when removing an item contained in the packaging box 110 through the opening 112, the protrusions 114 may come into contact with the hand, causing pain. In contrast, when the multiple thorn-like protrusions 14 are formed on the lid portion 25 and the separation portion 13 as in this embodiment shown in Fig. 4 , the protrusions 14 are not contacted with the hand when removing an item contained in the box body 1 through the opening 27, which is effective in preventing pain.

[0048] The pair of left and right first break lines 4 is not limited to the shape of the present embodiment. The pair of left and right first break lines 4 may, for example, extend in the vertical direction while sloping from the lower edge of the first side wall 20 toward the upper edge of the first header piece 11 so that the distance between them gradually increases. Alternatively, the pair of left and right first break lines 4 may, for example, extend in a vertically straight line from the lower edge of the first side wall 20 so as to be generally parallel to each other in the first side wall 20, and extend in the vertically straight line from the upper edge of the first header piece 11 so as to be sloping toward the upper edge of the first header piece 11 so that the distance between them gradually increases in the first side wall 20. The pair of left and right first break lines 4 may terminate at the upper edge of the first header piece 11 or at the left and right side edges of the first header piece 11. Alternatively, the pair of left and right first break lines 4 may, for example, extend in a vertically straight line from the lower edge of the first side wall 20 so as to be generally parallel to each other in the first side wall 20, and then bend 90° in the first header piece 11 and extend in the horizontal direction toward the left and right side edges of the first header piece 11.

[0049] 1, 2, and 4, a pair of left and right second break lines 5 are formed on the second side wall 21 of the body portion 2. The second break lines 5 are lines that break when an external force is applied, similar to the first break lines 4. The second break lines 5 can be configured as, for example, perforations or half-cut lines, and in this embodiment, they are configured as perforations.

[0050] The pair of left and right second break lines 5 extend in the front-rear direction at a distance from each other in the left-right direction, and reach from the front edge to the rear edge of the second side wall 21. The pair of left and right second break lines 5 are connected to the pair of left and right first break lines 4 at the rear edge of the second side wall 21, which reach the lower edge of the first side wall 20. This allows the opening start portion 26 between the pair of left and right second break lines 5 in the second side wall 21 to be peeled off.

[0051] When the opening start portion 26 is separated from the other portions of the second side wall 21 along the pair of second breaking lines 5 on the left and right, the lid portion 25 can then be opened.

[0052] The pair of left and right second fracture lines 5 extend generally parallel to each other in the front-rear direction from the front edge of the second side wall 21 to partway along the rear edge, and then extend in the front-rear direction while sloping from partway along the rear edge to the rear edge so that the gap between them gradually widens. This forms a narrow tab portion in the opening start portion 26, making it easy to peel off the opening start portion 26. A cut line 28 is formed in the center of the opening start portion 26 in the left-right direction, curving convexly toward the rear edge of the second side wall 21. The cut line 28 penetrates the second side wall 21 in the thickness direction, and an insertion piece 29 is formed in the area surrounded by the cut line 28.

[0053] The perforations that make up the second break line 5 are formed by arranging multiple notches 50 at intervals in the direction in which the first break line 5 extends. Each of the perforation notches 50 may be dot-like or linear, and in this embodiment, they are linear. In addition to being linear, each of the perforation notches 50 may have various shapes, such as a V-shape with one end bent or an arrow shape with one end widened into a V-shape. In this embodiment, each of the perforation notches 50 is V-shaped, similar to the first break line 4, and a detailed description thereof will be omitted here.

[0054] The pair of left and right second break lines 5 is not limited to the shape of the present embodiment. The pair of left and right second break lines 5 may, for example, extend linearly in the front-rear direction so as to be generally parallel to each other. Alternatively, the pair of left and right second break lines 5 may, for example, extend in the front-rear direction while inclining so that the distance between them gradually increases from the front edge toward the rear edge of the second side wall 21.

[0055] <Description of the item>

[0056] 4, a description 6 of the stored goods is displayed, for example, by printing, on the inside surface of the box body 1 and the inside surface of the header 10. Examples of the description 6 of the goods include, but are not limited to, the product name, the efficacy and effects of the product, the use and dosage of the product, a photo or diagram of an example use, the ingredients and amounts of the product, the features and appealing points of the product, how to use the product, precautions for use and handling of the product, information about the manufacturer and distributor, and figures, letters, symbols, logos, pictures, etc. for advertising and publicity of the product or for improving the design.

[0057] The description 6 regarding the item is displayed on the inner surfaces of the box body 1, namely, the inner surface of the fourth side wall 23 of the trunk 2, the inner surface of the third side wall 22, and the inner surface of the first side wall 20, which are easily visible to the user when the lid 25 is opened to open the box body 1. In this embodiment, in addition to the inner surface of the box body 1, the description 6 regarding the item is also displayed on the inner surface of the separation portion 13 of the first header piece 11 that is exposed when the separation portion 13 of the first header piece 11 separates from the second header piece 12 upon opening the box body 1, and on the inner surface of the second header piece 12.

[0058] In this manner, in this embodiment, the header 10 is composed of the first header piece 11 and the second header piece 12, and is configured so that the separation portion 13 of the first header piece 11 separates from the second header piece 12 when the box body 1 is opened, so that the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 can be used as an area for displaying the product description 6. As a result, there is no need to separately store a document containing the product description 6 inside the packaging box 100, which reduces costs and simplifies the manufacturing process.

[0059] In addition, the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 can be used as areas for displaying the description 6 regarding the item, thereby increasing the display area and allowing the description 6 regarding the item to be displayed sufficiently.

[0060] Furthermore, before the box body 1 is opened, the first header piece 11 and the second header piece 12 are overlapped, and the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 are not exposed. Therefore, even if the items contained in the box body 1 move or rattle during transportation, the product instructions 6 displayed on the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 will not come into contact with the items, and the instructions will not be erased or become difficult to see due to friction with the items. Therefore, it is effective to display important instructions such as how to use the product and precautions for using and handling the product on the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12.

[0061] It should be noted that the areas on the inner surfaces of the box body 1 and the header 10 where the description 6 regarding the item is displayed are not limited to the areas described in this embodiment. For example, the description 6 regarding the item may be displayed on either the inner surface of the separation portion 13 of the first header piece 11 or the inner surface of the second header piece 12. For the body 2, the description 6 regarding the item may be displayed on at least one of the inner surface of the first side wall 20, the inner surface of the third side wall 22, the inner surface of the fourth side wall 23, and the fifth side wall 24.

[0062] <Blank Sheet> The above-described packaging box 100 can be assembled using one blank sheet 101 shown in Fig. 6. Note that the shape of the blank sheet 101 is merely an example and is not limited to the shape shown in Fig. 6. The blank sheet 101 can be formed using various known paper materials such as cardboard and corrugated cardboard, or a resin material, but the material of the blank sheet 100 is not limited to the above-mentioned materials.

[0063] In the blank sheet 101, the plate material constituting the second side wall 21, the plate material constituting the first side wall 20 and first header piece 11, the plate material constituting the second header piece 12, the plate material constituting the third side wall 22, the plate material constituting the fourth side wall 23, and the plate material constituting the fifth side wall 24 are connected in this order with folds L1-L5 between adjacent plate materials.

[0064] In addition, the plate material constituting the second flap 31 is connected to both sides of the plate material constituting the second side wall 21 via a fold L6, the plate material constituting the fourth flap 33 is connected to both sides of the part of the plate material constituting the first side wall 20 and the first header piece 11 that comes into contact with the first side wall 20 via a fold L7, the plate material constituting the first flap 30 is connected to both sides of the plate material constituting the third side wall 22 via a fold L8, and the plate material constituting the third flap 32 is connected to both sides of the plate material constituting the fourth side wall 23 via a fold L9.

[0065] For each of the fold lines L1 to L9, a type having ease of folding suitable for each position can be selected from among many known types.

[0066] Next, the procedure for assembling the packaging box 100 using the blank sheet 101 will be described. First, the blank sheet 101 is folded 180 degrees at fold line L2 with a mountain fold and then folded 90 degrees at fold line L3 with a valley fold, thereby overlapping the inner surfaces (the surfaces with the product description 6) of the plate material constituting the first side wall 20 and first header piece 11 and the plate material constituting the second header piece 12. Next, the blank sheet 101 is folded 90 degrees at fold line L4 with a mountain fold and then folded 90 degrees at fold line L5 with a mountain fold, thereby aligning the plate material constituting the fourth side wall 23 with the plate material constituting the first side wall 20 and first header piece 11, and the plate material constituting the fifth side wall 24 with the plate material constituting the third side wall 22. Next, the blank sheet 101 is folded 90 degrees at fold line L1 with a mountain fold, thereby overlapping the plate material constituting the second side wall 21 with the outer surface of the plate material constituting the fifth side wall 24 and securing them together using adhesive or the like. Then, the blank sheet 101 is folded 90 degrees at folds L6 and L8, and then at fold L9, so that the plate material constituting the third flap 32 is placed on the outside of the plate material constituting the first flap 30 and the plate material constituting the second flap 31. Finally, the blank sheet 101 is folded 90 degrees at fold L7, so that the plate material constituting the fourth flap 33 is placed on the outside of the plate material constituting the third flap 32 and fixed using an adhesive or the like. In this way, the packaging box 100 is assembled.

[0067] <How to Use the Packaging Box> Next, a method for opening the assembled packaging box 1 will be described. First, the narrow tab portion of the opening start portion 26 of the second side wall 21 is pinched and the opening start portion 26 is pulled and peeled along the pair of left and right second break lines 5. Then, while still pinching the tab portion of the opening start portion 26, the lid portion 25 of the first side wall 20 is pulled and peeled along the pair of left and right first break lines 4 to open the lid portion 25 and form an opening 27. Further, the separation portion 13 of the first header piece 11 is pulled and peeled along the pair of left and right first break lines 4 to separate the separation portion 13 from the second header piece 12. This makes it possible to remove an item (not shown) from the box body 1 through the opening 27, as shown in FIG. 4 .

[0068] At this time, the inner surface of the trunk portion 2 of the box body 1 is largely exposed, including the inner surface of the lid portion 25, and the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 are also exposed, making the description 6 regarding the item displayed on them visible.

[0069] When resealing the opened packaging box 1, the tab portion of the opening start portion 26 is pinched to close the lid portion 25 and close the opening 27, and the separation portion 13 is overlapped with the second header piece 12. Then, while still pinching the tab portion of the opening start portion 26, the opening start portion 26 is overlapped with the fifth side wall 24, and at this time, the insertion piece 29 of the opening start portion 26 is inserted into the insertion hole (notch 28B) of the fifth side wall 24. This fixes the opening start portion 26 to the fifth side wall 24, preventing the lid portion 25 from opening. Thereafter, if necessary, the insertion piece 29 of the opening start portion 26 can be removed from the insertion hole (notch 28B) of the fifth side wall 24 to open the lid portion 25 and remove the item.

[0070] <Functions and Effects of Packaging Box> As described above, the packaging box 100 of this embodiment comprises a box body 1 capable of accommodating articles and a header 10 extending upward from the box body 1, the box body 1 including a first side wall 20 on which a pair of left and right first break lines 4 are formed, and is configured so that a lid portion 25 between the pair of left and right first break lines 4 in the first side wall 20 opens to form an opening 27 through which articles can be removed. The header 10 also comprises a first header piece 11 continuing above the first side wall 20 and a second header piece 12 overlapping the first header piece 11, the pair of left and right first break lines 4 extending to the upper edge or left and right side edges of the first header piece 11, and the header 10 is configured so that at least a portion of the first header piece 11 (separating portion 13) together with the lid portion 25 is peeled off along the pair of left and right first break lines 4 to separate from the second header piece 12.

[0071] In the packaging box 100 of this embodiment, due to the above-described configuration, when the box body 1 is opened, the separation portion 13 of the first header piece 11 is peeled off together with the lid portion 25 of the first side wall 20, and the separation portion 13 separates from the second header piece 12. Therefore, with the packaging box 100 of this embodiment, the inner surface of the separation portion 13 and the inner surface of the second header piece 12 can be used as an area for displaying the product description 6. As a result, there is no need to separately store a document containing the product description 6 inside the packaging box 100, which reduces manufacturing costs and simplifies the manufacturing process.

[0072] In addition, with the packaging box 100 of this embodiment, the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 can be used as an area for displaying the product description 6. This increases the display area for the product description 6, allowing the product description 6 to be displayed sufficiently.

[0073] Additionally, in the packaging box 100 of this embodiment, the first header piece 11 and the second header piece 12 are overlapped before the box body 1 is opened, and the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 are not exposed. Therefore, with the packaging box 100 of this embodiment, even if the items contained in the box body 1 move or rattle during transportation, the product-related instructions 6 displayed on the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 do not come into contact with the items, and the instructions are not erased or obscured by friction with the items. Therefore, for example, by displaying important instructions such as product usage instructions and product usage and handling precautions on the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12, the important instructions can be reliably viewed by the user. In addition, the inner surface of the separation portion 13 of the first header piece 11 and the inner surface of the second header piece 12 are arranged side by side below the inner surface of the open lid portion 25, so that the explanation 6 regarding the item can be displayed in a position that is easy for the user to see.

[0074] In addition, the packaging box 100 of this embodiment does not change its shape significantly compared to conventional packaging boxes with headers, and there is no significant increase in the amount of blank sheets 101 used or the effort and complexity involved in assembling the blank sheets 101. Therefore, the packaging box 100 of this embodiment can be produced stably in the same way as conventional packaging boxes with headers.

[0075] In addition, the packaging box 100 of this embodiment does not change its shape significantly compared to conventional packaging boxes with headers, and there is no significant increase in the amount of blank sheets 101 used or the effort and complexity involved in assembling the blank sheets 101. Therefore, the packaging box 100 of this embodiment can be produced stably in the same way as conventional packaging boxes with headers.

[0076] In addition, according to the packaging box 100 of this embodiment, the second side wall 21 includes the opening start portion 26, and opening begins from the second side wall 21 to open the lid portion 25 of the first side wall 20, making it easy to open and preventing the box from deforming significantly after opening. Therefore, it is easy to reseal.

[0077] Additionally, in the packaging box 100 of this embodiment, the pair of left and right first break lines 4 are perforations, and the multiple incisions 40 constituting the perforations have second portions 42, which are one end portion, bent toward the left and right side edges of the first side wall 20 and the left and right side edges of the first header piece 11. Therefore, in the packaging box 100 of this embodiment, as shown in Fig. 4, multiple thorn-like protrusions 14 are formed on the sides of the lid portion 25 and the separation portion 13 when the lid portion 25 of the first side wall 20 and the separation portion 13 of the first header piece 11 are peeled away. Therefore, when removing an item stored in the box body 1 through the opening 27, the user's hand does not come into contact with the protrusions 14, and therefore the user does not feel any pain.

[0078] Although one embodiment of the packaging box of the present disclosure has been described above, the packaging box of the present disclosure is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present disclosure. For example, the following modifications are possible. Furthermore, the gist of the following modifications can be combined as appropriate.

[0079] In the above-described embodiment, the second break line 5 is formed in the second side wall 21, and opening is started from the opening start portion 26 of the second side wall 21 to open the lid portion 25 of the first side wall 20. In contrast, in one modified example, the second break line 5 is not formed in the second side wall 21, and opening is started from the lid portion 25 of the first side wall 20 to open the lid portion 25.

[0080] In the above-described embodiment, the closure section 3 is composed of four flaps 30-33, but the configuration of the closure section 3 is not particularly limited, and the number and shape of the flaps are not particularly limited as long as they can close both ends of the body section 2 of the box body 1.

[0081] In the above-described embodiment, the second header piece 12 is connected to the upper edge of the first header piece 11, and the second header piece 12 is folded back toward the first header piece 11 to overlap the first header piece 11 and the second header piece 12. In contrast, in one modified example, the second header piece 12 is not connected to the upper edge of the first header piece 11, but the first header piece 11 is attached to the second header piece 12 at a portion other than the separation portion 13, so that the first header piece 11 and the second header piece 12 are overlapped.

[0082] In the above-described embodiment, the body 2 of the box body 1 is configured so that the back, top, front, and bottom surfaces are cylindrical, and the left and right side surfaces serve as the closures 3. In contrast, in one modified example, the body 2 of the box body 1 can be configured so that the back, left and right side surfaces, and front surface are cylindrical, and the top and bottom surfaces serve as closures that close the openings at both ends of the body 2.
