[0046] The packaging box of the present invention is used to accommodate items such as drugs, quasi-drugs, medical devices, or cosmetics, and is used for transporting and displaying the items. Hereinafter, an embodiment of the packaging box of the present invention will be described with reference to the accompanying drawings.

[0047] <Overall Structure of the Packaging Box>

[0048] As Figures 1 to 4 shown, the packaging box 100 includes a box body 1 capable of accommodating items and a head 10 protruding from the box body 1. In the present invention, the direction in which the head 10 extends from the box body 1 is defined as the upward direction. Specifically, the Figure 1 diagonally upper right direction in (A) is defined as the upward direction, and the diagonally lower left direction opposite thereto is defined as the downward direction. The direction perpendicular to the main surface of the head 10 is defined as the front-rear direction. Specifically, the Figure 1 diagonally upper left direction in (A) is defined as the front direction, and the diagonally lower right direction opposite thereto is defined as the rear direction. The direction perpendicular to the up-down direction and the front-rear direction is defined as the left-right direction. Specifically, the Figure 1 upward direction in (A) is defined as the right direction, and the downward direction opposite thereto is defined as the left direction.

[0049] The shape of the box body 1 is, for example, a hexahedron, and is a cuboid in the present embodiment. The box body 1 includes a cylindrical main body portion 2 and a pair of closing portions 3 that close the openings at both ends of the axial direction extending left and right in the main body portion 2. The main body portion 2 has a quadrilateral cylindrical shape in a cross section perpendicular to the axial direction, and has a front surface on the front side, a rear surface opposite to the front surface on the rear side, a top surface perpendicular to the front surface and the rear surface on the upper side, and a bottom surface perpendicular to the front surface and the rear surface and opposite to the top surface on the lower side. The head 10 extends upward from the box body 1 at the rear side of the main body portion 2.

[0050] The head 10 is a part where small holes are formed for hanging the packaging box 1 on a hook during, for example, an exhibition or display, or a part for displaying instructions about the article accommodated in the packaging box 1, especially for promoting or advertising the article. The head 10 includes a first head piece 11 and a second head piece 12 that overlap each other. The first head piece 11 and the second head piece 12 are in the form of thin sheets, and the strength of the head 10 is increased by overlapping the first head piece 11 and the second head piece 12.

[0051] The first head piece 11 is located above and adjacent to (connected above) the first side wall 20 that forms the rear surface of the main body 2. The first head piece 11 and the first side wall 20 are made of the same sheet material, and the lower part of the sheet material forms the first side wall 20 and the upper part forms the first head piece 11.

[0052] A pair of left and right first breaking lines 4 are formed on the first side wall 20 of the main body 2. A pair of left and right second breaking lines 5 are formed on the second side wall 21 that forms the bottom surface of the main body 2. The second side wall 21 is connected to the lower edge of the first side wall 20 and is substantially perpendicular to the first side wall 20. The second breaking line 5 is continuously connected to the first breaking line 4. The part between the pair of left and right second breaking lines 5 in the second side wall 21 is the opening starting part 26. The part between the pair of left and right first breaking lines 4 in the first side wall 20 is the lid part 25. When the opening starting part 26 is torn along the pair of left and right second breaking lines 5 and separated from the other part of the second side wall 21, the lid part 25 can be opened. When the lid part 25 is torn along the pair of left and right first breaking lines 4 and separated from the other part of the first side wall 20, as Figure 4 shown, the lid part 25 opens to form an opening 27, and through this opening 27, the article accommodated in the box body 1 can be taken out. This enables the article to be taken out from the box body 1.

[0053] Next, the box body 1 and the head 10 that constitute the packaging box 100 of the present embodiment and the blank 101 for forming the packaging box 100 (as Figure 6 shown) will be described in detail.

[0054] <Box body>

[0055] As Figures 1 to 4 shown, the main body 2 of the box body 1 includes a first side wall 20 that forms the rear surface, a second side wall 21 that forms the bottom surface, a third side wall 22 that forms the top surface, a fourth side wall 23 that forms the front surface, and a fifth side wall 24 that forms the bottom surface. Each side wall 20 - 24 is in the form of a thin sheet, each side wall 20 - 23 is rectangular (rectangular in this embodiment), and the fifth side wall 24 is trapezoidal. The sizes of the first side wall 20 and the fourth side wall 23 are substantially the same. The sizes of the second side wall 21 and the third side wall 22 are substantially the same. The fifth side wall 24 is smaller than the second side wall 21.

[0056] The second side wall 21 is connected to the lower edge of the first side wall 20. The third side wall 22 is opposite to the second side wall 21. The fourth side wall 23 is opposite to 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 substantially 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 substantially perpendicular to the fourth side wall 23. The fifth side wall 24 overlaps (covers) the inner side of the second side wall 21, and at least a part 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, a double-sided tape, etc. In each of the side walls 20-24, the inner side means the side facing the inner space of the box body 1, and the outer side means the opposite side.

[0057] At the central position in the left-right direction of the second side wall 21, a cutting line 28A that curves convexly toward the rear edge of the second side wall 21 is formed. The cutting line 28A penetrates the second side wall 21 in the thickness direction, and an insert 29 is formed in the area surrounded by the cutting line 28.

[0058] At the central position in the left-right direction of the fifth side wall 24, a cutting line 28B extending in the left-right direction is formed. The cutting line 28B penetrates the fifth side wall 24 in the thickness direction and forms an insertion hole into which the insert 29 can be inserted.

[0059] A pair of closing portions 3 of the box body 1 are located at both ends in the left-right direction of the main body portion 2 and constitute the left and right sides of the box body 1. Each of the closing portions 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 has a thin sheet shape and a substantially rectangular shape. The thickness of each of the flaps 30-33 is substantially the same as the thickness of each of the side walls 20-24 of the main body portion 2.

[0060] The first flap 30 is connected to the left and right side edges of the third side wall 22 of the main body portion 2 and is substantially 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 main body portion 2 and is substantially perpendicular to the second side wall 21. The first flap 30 and the second flap 31 have substantially the same size. The lengths of the first flap 30 and the second flap 31 in the front-rear direction are smaller than the lengths of the second side wall 21 and the third side wall 22 in the front-rear direction (the depth of the main body portion 2). The lengths of the first flap 30 and the second flap 31 in the up-down direction are approximately half of the length of the fourth side wall 23 in the up-down direction (the height of the main body portion 2), and the front ends of the first flap 30 and the second flap 31 face each other with a gap therebetween.

[0061] The third wing 32 is connected to the left and right side edges of the fourth side wall 23 of the main body 2 and is substantially perpendicular to the fourth side wall 23. The fourth wing 33 is connected to the left and right side edges of the first side wall 20 of the main body 2 and is substantially perpendicular to the first side wall 20. The length of each third wing 32 in the up-and-down direction is less than the length of the fourth side wall 23 in the up-and-down direction (the height of the main body 2). The length of each third wing 32 in the front-and-back direction is less than the lengths of the second side wall 21 and the third side wall 22 in the front-and-back direction (the depth of the main body 2). The size of each fourth wing 33 is larger than the size of each third wing 32. The length of each fourth wing 33 in the up-and-down direction is substantially the same as the length of the fourth side wall 23 in the up-and-down direction (the height of the main body 2). The length of each fourth wing 33 in the front-and-back direction is substantially the same as the lengths of the second side wall 21 and the third side wall 22 in the front-and-back direction (the depth of the main body 2).

[0062] The third wing 32 overlaps (covers) the outside of the first wing 30 and the second wing 31, and the fourth wing 33 overlaps (covers) the outside of the third wing 32. At least a part of the third wing 32 and the fourth wing 33 is fixed using an adhesive, a pressure-sensitive adhesive, a double-sided tape, etc., thereby closing the openings at both ends of the main body 2 in the left-and-right direction.

[0063] In the present embodiment, each closing portion 3 is composed of four wings 30-33. However, the structure of the closing portion 3 is not particularly limited. As long as both ends of the main body 2 can be closed, the number and shape of the wings are not particularly limited.

[0064] <Head>

[0065] As Figures 1 to 4 shown, the head pieces 11 and 12 of the head 10 both have a thin sheet shape and a rectangular shape (a rectangle in the present embodiment). The first head piece 11 and the second head piece 12 have substantially the same size. The thickness of each head piece 11, 12 is substantially the same as the thickness of each side wall 20-24 of the main body 2.

[0066] The first head piece 11 extends upward from the first side wall 20 of the main body 2. In other words, the first head piece 11 is located above and adjacent to the first side wall 20, and is flush with the first side wall 20, such that the first side wall 20 extends upward, and the first side wall 20 and the first head piece 11 are configured in a continuous manner, such that the outer surfaces of the first side wall 20 and the first head piece 11 are in the same plane, and the inner surfaces of the first side wall 20 and the first head piece 11 are in the same plane. Therefore, in the present embodiment, there is no obvious boundary between the first side wall 20 and the first head piece 11, and they are flat, and there is no height difference or unevenness between the two. A crease or a break line may be provided between the first side wall 20 and the first head piece 11, and the first head piece 11 may be located above and adjacent to the first side wall 20, such that there is an obvious boundary between the two.

[0067] The length of the first head piece 11 in the left - right direction is substantially the same as the length of the first side wall 20 in the left - right direction. The length of the first head piece 11 in the left - right direction may, for example, become narrower or wider as it goes upward.

[0068] The second head piece 12 is connected to the upper edge of the first head piece 11. The second head piece 12 overlaps the first head piece 11 by being folded back with respect to the first head piece 11 at the upper edge of the first head piece 11. The second head piece 12 simply overlaps the first head piece 11, and in the present embodiment, it is not fixed to the inner surface of the first head piece 11 using an adhesive, a pressure - sensitive adhesive, a double - sided tape, etc.

[0069] The third side wall 22 of the main body 2 is connected to the lower edge of the second head piece 12, and the second head piece 12 is substantially perpendicular to the third side wall 22.

[0070] <First break line>

[0071] As Figure 1 、 Figure 2 and Figure 4 shown, a pair of left - right first break lines 4 are formed in the first side wall 20 of the main body 2 and the first head piece 11 of the head 10. The first break line 4 is designed to be a line that breaks when an external force is applied. The first break line 4 may be constituted by, for example, a perforation line, a half - cut line, etc. In the present embodiment, the first break line 4 is constituted by a perforation line.

[0072] A pair of left and right first breaking lines 4 linearly extend in the vertical direction, being spaced apart from each other in the left - right direction and being substantially parallel, and reaching from the lower edge of the first side wall 20 to the upper edge of the first head piece 11. This enables the cover portion 25 between the pair of left and right first breaking lines 4 in the first side wall 20 to be torn off together with the separating portion 13 between the pair of left and right first breaking lines 4 in the first head piece 11.

[0073] As Figure 4 shown, when the cover portion 25 is separated from the other part of the first side wall 20 along the pair of left and right first breaking lines 4, the cover portion 25 is opened to form an opening 27, through which the article accommodated in the box body 1 can be taken out. In addition, when the separating portion 13 is separated from the other part of the first head piece 11 along the pair of left and right first breaking lines 4, the separating portion 13 is separated from the second head piece 12, so that the inner surface of the separating portion 13 can be exposed.

[0074] As Figure 1 and Figure 2 shown, the perforation line forming the first breaking line 4 is formed by arranging a plurality of incisions 40 at intervals in the direction in which the first breaking line 4 extends. Each incision 40 of the perforation line can be dot - shaped or linear, and is linear in the present embodiment. Each incision 40 of the perforation line can be of various shapes, such as a straight line, a "く" - shaped (chevron - shaped) with one end bent, or an arrow shape with one end widened in a V - shape. In the present embodiment, each incision 40 of the perforation line has a "く" - shaped.

[0075] Each "く" - shaped incision 40 includes a first portion 41 extending in the direction in which the first breaking line 4 extends and a second portion 42 bent from the first portion 41. The first portion 41 of the incision 40 is arranged linearly. The second portion 42 of the incision 40 can be bent to the left or right with respect to the direction in which the first breaking line 4 extends. In the present embodiment, the second portion 42 is bent toward the left and right side edges of the first side wall 20 and the left and right side edges of the first head piece 11. More specifically, the left first breaking line 4 is bent toward the left side edge of the first side wall 20 and the left side edge of the first head piece 11, and the right first breaking line 4 is bent toward the right side edge of the first side wall 20 and the right side edge of the first head piece 11.

[0076] Therefore, as Figure 4 shown, when the cover portion 25 of the first side wall 20 and the separating portion 13 of the first head piece 11 are torn off, a plurality of ridge - like protrusions 14 are formed on the cover portion 25 side and the separating portion 13 side. If the second portion 42 of each incision 40 is bent to the opposite side of the present embodiment, that is Figure 8In the case of the existing packaging box 110 shown, a plurality of ridge-like protrusions 114 remain on the left and right edge sides of the opening 112. Therefore, when taking out the item accommodated in the packaging box 110 through the opening 112, the user's hand may come into contact with the protrusions 114, and the user may feel pain or the like. In contrast, in the case where a plurality of ridge-like protrusions 14 are formed on the lid portion 25 side and the separation portion 13 side as in the present embodiment shown in Figure 4 when the item accommodated in the box body 1 is taken out through the opening 27, the user's hand does not come into contact with the protrusions 14, so there is no pain or the like, which is effective.

[0077] The shape of the pair of left and right first fracture lines 4 is not limited to the shape of the present embodiment. The pair of left and right first fracture lines 4 can, for example, extend in the vertical direction while being inclined on one side so that the distance between the two gradually increases from the lower edge of the first side wall 20 to the upper edge of the first head piece 11. Or, the pair of left and right first fracture lines 4 can, for example, extend linearly in the vertical direction from the lower edge of the first side wall 20 so as to be substantially parallel to each other in the first side wall 20, and in the first head piece 11, it can extend while being inclined in the vertical direction so that the distance between the two gradually increases toward the upper edge of the first head piece 11. The ends of the pair of left and right first fracture lines 4 can reach the upper edge of the first head piece 11, or can reach the left and right side edges of the first head piece 11. Or, the pair of left and right first fracture lines 4 can, for example, extend linearly in the vertical direction from the lower edge of the first side wall 20 so as to be substantially parallel to each other in the first side wall 20, and in the first head piece 11, it can be bent by 90° and extend in the left-right direction to the left and right side edges of the first head piece 11.

[0078] <Second fracture line>

[0079] As shown in Figure 1 , Figure 2 and Figure 4 a pair of left and right second fracture lines 5 are formed on the second side wall 21 of the main body portion 2. Similar to the first fracture line 4, the second fracture line 5 is designed as a line that breaks when an external force is applied. The second fracture line 5 can be constituted by, for example, a perforation line or a half-cut line. In the present embodiment, the second fracture line 5 is constituted by a perforation line.

[0080] The pair of left and right second fracture lines 5 extend in the front-rear direction so as to be spaced apart from each other in the left-right direction, and reach the rear side edge from the front side edge of the second side wall 21. The pair of left and right second fracture lines 5 are connected to the pair of left and right first fracture lines 4 that reach the lower edge of the first side wall 20 at the rear side edge of the second side wall 21. This enables the opening start portion 26 between the pair of left and right second fracture lines 5 of the second side wall 21 to be torn off.

[0081] When the opening start portion 26 is separated from the other part of the second side wall 21 along the pair of left and right second breaking lines 5, the lid portion 25 can be opened.

[0082] The pair of left and right second breaking lines 5 extend in the front-rear direction from the front edge of the second side wall 21 so as to be substantially parallel to each other until a point on the way from the front edge to the rear edge, and are inclined while extending in the front-rear direction from this point to the rear edge so that the distance between the pair of left and right second breaking lines gradually increases. As a result, a tab portion having a narrow width is formed at the opening start portion 26, and the opening start portion 26 can be easily torn off. A cutting line 28 that bulges and bends toward the rear edge of the second side wall 21 is formed at the center position in the left-right direction of the opening start portion 26. The cutting line 28 penetrates the second side wall 21 in the thickness direction, and an insert 29 is formed in the area surrounded by the cutting line 28.

[0083] The perforation lines forming the second breaking lines 5 are formed by arranging a plurality of cuts 50 at intervals in the direction in which the first breaking lines 5 extend. Each cut 50 of the perforation line may be dot-shaped or linear, and is linear in the present embodiment. Each cut 50 of the perforation line may have various shapes, such as a straight line, a "く" shape with one end bent, or an arrow shape with one end widened in a V shape. In the present embodiment, each cut 50 of the perforation line has the same "く" shape as the first breaking line 4. A detailed description thereof is omitted here.

[0084] The shape of the pair of left and right second breaking lines 5 is not limited to the shape of the present embodiment. The pair of left and right second breaking lines 5 may, for example, extend linearly in the front-rear direction so that they are substantially parallel to each other. Alternatively, the pair of left and right second breaking lines 5 may, for example, extend while being inclined in the front-rear direction so that the distance between them gradually increases from the front edge to the rear edge of the second side wall 21.

[0086] As Figure 4 shown, descriptions 6 of the accommodated article are displayed, for example, by printing or the like on the inner surface of the box body 1 and the inner surface of the head 10. Examples of the description 6 of the article include, but are not limited to, the product name, efficacy and effects, uses and dosages of the product, photos and diagrams of usage examples for illustrative purposes, ingredients and quantities of the product, features and selling points of the product, usage methods of the product, precautions for the use and handling of the product, information about the manufacturer and the seller, charts, texts, symbols, logos, and illustrations for promoting and advertising the product or improving the product design, etc.

[0087] Regarding the description 6 of the article, on the inner surface of the box body 1, it is displayed on the inner surface of the fourth side wall 23, the inner surface of the third side wall 22, and the inner surface of the first side wall 20 of the main body portion 2 that are easily visually recognizable by the user when the lid portion 25 is opened to open the box body 1. In the present embodiment, in addition to the inner surface of the box body 1, the description 6 of the article is also displayed on the inner surface of the separation portion 13 and the inner surface of the second head piece 12, which are exposed when the box body 1 is opened and the separation portion 13 of the first head piece 11 is separated from the second head piece 12.

[0088] Therefore, in the present embodiment, the head 10 is composed of the first head piece 11 and the second head piece 12, and is configured such that when the box body 1 is opened, the separation portion 13 of the first head piece 11 is separated from the second head piece 12. Therefore, the inner surface of the separation portion 13 of the first head piece 11 and the inner surface of the second head piece 12 can be used as areas for displaying the description 6 of the article. As a result, there is no need to separately accommodate in the packaging box 100 a document recording the description 6 of the article, which can reduce production costs and simplify the production process.

[0089] In addition, since the inner surface of the separation portion 13 of the first head piece 11 and the inner surface of the second head piece 12 can be used as areas for displaying the description 6 of the article, the display area is increased, and the description 6 of the article can be fully displayed.

[0090] In addition, before the box body 1 is opened, the first head piece 11 and the second head piece 12 overlap each other, and the inner surface of the separation portion 13 of the first head piece 11 and the inner surface of the second head piece 12 are not exposed. Therefore, even if the article accommodated in the box body 1 moves or shakes during transportation or the like, the description 6 of the article displayed on the inner surface of the separation portion 13 of the first head piece 11 and the inner surface of the second head piece 12 will not come into contact with the article, and its display will not disappear or become difficult to see due to friction with the article. Therefore, it is effective to display important information, such as the usage method of the product and the precautions for the use and handling of the product, on the inner surface of the separation portion 13 of the first head piece 11 and the inner surface of the second head piece 12.

[0091] The areas for displaying the description 6 of the article on the inner surface of the box body 1 and the inner surface of the head 10 are not limited to the areas described in the present embodiment. For example, the description 6 of the article can be displayed on either the inner surface of the separation portion 13 of the first head piece 11 or the inner surface of the second head piece 12. In the main body portion 2, the description 6 of the article can 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.

[0092] <Blank sheet>

[0093] The above packaging box 100 can be assembled using Figure 6 a blank 101 as shown. The shape of the blank 101 is merely an example and is not limited to Figure 6 the shape shown. The blank 101 can be formed using various known paper materials such as thick paper and corrugated cardboard, or formed using a resin material. However, the material of the blank 100 is not limited to the above materials.

[0094] In the blank 101, the sheet forming the second side wall 21, the sheet forming the first side wall 20 and the first head piece 11, the sheet forming the second head piece 12, the sheet forming the third side wall 22, the sheet forming the fourth side wall 23, and the sheet forming the fifth side wall 24 are connected in this order by creases L1 - L5 between adjacent sheets.

[0095] The sheet forming the second flap 31 is connected to each side of the sheet forming the second side wall 21 via a crease L6 therebetween, the sheet forming the fourth flap 33 is connected to each side of the first side wall 20 portion of the sheet forming the first side wall 20 and the first head piece 11 via a crease L7 therebetween, the sheet forming the first flap 30 is connected to each side of the sheet forming the third side wall 22 via a crease L8 therebetween, and the sheet forming the third flap 32 is connected to each side of the sheet forming the fourth side wall 23 via a crease L9 therebetween.

[0096] As the creases L1 - L9, a type that is easy to fold and suitable for each position can be selected from various known types.

[0097] Next, the process of assembling the packaging box 100 using the blank 101 will be described. First, the blank 101 is folded 180 degrees in a mountain fold manner at the crease L2, and folded 90 degrees in a valley fold manner at the crease L3, so that the inner surfaces (the surfaces showing the description 6 of the article) of the plate material forming the first side wall 20 and the first head piece 11 and the plate material forming the second head piece 12 are superimposed on each other. Then, the blank 101 is folded 90 degrees in a mountain fold manner at the crease L4, and folded 90 degrees in a mountain fold manner at the crease L5, so that the plate material forming the fourth side wall 23 is opposite to the plate material forming the first side wall 20 and the first head piece 11, and the plate material forming the fifth side wall 24 is opposite to the plate material forming the third side wall 22. Then, the blank 101 is folded 90 degrees in a mountain fold manner at the crease L1, and the plate material forming the second side wall 21 is superimposed on the outer side of the plate material forming the fifth side wall 24 and fixed using an adhesive or the like. Then, the blank 101 is folded 90 degrees in a mountain fold manner at the creases L6 and L8, and folded 90 degrees in a mountain fold manner at the crease L9, and the plate material forming the third flap 32 is superimposed on the outer sides of the plate material forming the first flap 30 and the plate material forming the second flap 31. Finally, the blank 101 is folded 90 degrees in a mountain fold manner at the crease L7, and the plate material forming the fourth flap 33 is superimposed on the outer side of the plate material forming the third flap 32 and fixed using an adhesive or the like. The packaging box 100 is assembled in this way.

[0098] <Method of using the packaging box>

[0099] Next, the method of opening the assembled packaging box 1 will be described. First, the narrow pull tab portion in the opening start portion 26 of the second side wall 21 is pinched, and the opening start portion 26 is torn along the pair of left and right second tear lines 5. While the pull tab portion of the opening start portion 26 is pinched, the lid portion 25 of the first side wall 20 is torn along the pair of left and right first tear lines 4, so as to open the lid portion 25 to form an opening 27. Further, the separation portion 13 of the first head piece 11 is torn along the pair of left and right first tear lines 4, thereby separating the separation portion 13 from the second head piece 12. As Figure 4 shown, this enables the article (not shown) in the box body 1 to be taken out through the opening 27.

[0100] At this time, the inner surface of the main body portion 2 of the box body 1 (including the inner surface of the lid portion 25) is substantially exposed, and the inner surfaces of the separation portion 13 of the first head piece 11 and the inner surface of the second head piece 12 are also exposed, making the description 6 of the article shown on these inner surfaces visible.

[0101] When the opened packaging box 1 is re-closed, the tab portion of the opening start portion 26 is pinched, the lid portion 25 is closed to close the opening 27, and the separation portion 13 overlaps the second head piece 12. In a state where the tab portion of the opening start portion 26 is pinched, the opening start portion 26 overlaps the fifth side wall 24, and at this time, the insert 29 of the opening start portion 26 is inserted into the insertion hole (cutout 28B) of the fifth side wall 24. As a result, the opening start portion 26 is fixed to the fifth side wall 24, and the opening of the lid portion 25 is restricted. Then, if necessary, the insert 29 of the opening start portion 26 can be pulled out from the insertion hole (cutout 28B) of the fifth side wall 24 to open the lid portion 25 and remove the article.

[0102] <Functions and effects of the packaging box>

[0103] As described above, the packaging box 100 of the present embodiment includes a box body 1 capable of accommodating an article and a head portion 10 extending upward from the box body 1. The box body 1 includes a first side wall 20, in which a pair of left and right first tear lines 4 are formed, and is configured to form an opening 27 through which the article can be taken out by opening the lid portion 25 between the pair of left and right first tear lines 4 in the first side wall 20. The head portion 10 includes a first head piece 11 connected above the first side wall 20 and a second head piece 12 overlapping the first head piece 11. The pair of left and right first tear lines 4 extend to the upper edge or the left and right side edges of the first head piece 11, and the head portion 10 is configured such that at least a part (separation portion 13) of the first head piece 11 is torn along the pair of left and right first tear lines 4 together with the lid portion 25 and separated from the second head piece 12.

[0104] In the packaging box 100 of the present embodiment, due to the above configuration, when the box body 1 is opened, the separation portion 13 of the first head piece 11 is torn together with the lid portion 25 of the first side wall 20, and the separation portion 13 is separated from the second head piece 12. Therefore, according to the packaging box 100 of the present embodiment, the inner surface of the separation portion 13 and the inner surface of the second head piece 12 can be used as areas for displaying the description 6 of the article. As a result, there is no need to separately accommodate a document having the description 6 of the article in the packaging box 100, which can reduce the production cost and simplify the production process.

[0105] In addition, according to the packaging box 100 of the present embodiment, the inner surface of the separation portion 13 of the first head piece 11 and the inner surface of the second head piece 12 can be used as areas for displaying the description 6 of the article. Therefore, the display area of the description 6 of the article is increased, and the description 6 of the article can be sufficiently displayed.

[0106] In addition, in the packaging box 100 of the present embodiment, before the box body 1 is opened, the first head piece 11 and the second head piece 12 overlap each other, and the inner surfaces of the separation portions 13 of the first head piece 11 and the inner surfaces of the second head piece 12 are not exposed. Therefore, according to the packaging box 100 of the present embodiment, even if the articles accommodated in the box body 1 move or shake during transportation or the like, the explanations 6 about the articles displayed on the inner surfaces of the separation portions 13 of the first head piece 11 and the inner surfaces of the second head piece 12 will not come into contact with the articles, and will not disappear or become difficult to see due to friction with the articles. Therefore, for example, by displaying important explanations such as the usage method of the product and precautions for the use and handling of the product on the inner surfaces of the separation portions 13 of the first head piece 11 and the inner surfaces of the second head piece 12, it is possible to ensure that the user can see the important explanations. In addition, since the inner surfaces of the separation portions 13 of the first head piece 11 and the inner surfaces of the second head piece 12 are arranged and disposed below the inner surface of the opened lid portion 25, the explanations 6 about the articles can be displayed at a position where the user can easily see them.

[0107] In addition, the shape of the packaging box 100 of the present embodiment is not significantly different from the shape of the existing packaging box with a head, and the amount of the blank 101 used and the workload and complexity in the assembling process using the blank 101 are not significantly increased. Therefore, the packaging box 100 of the present embodiment can be produced as stably as the existing packaging box with a head.

[0108] In addition, the shape of the packaging box 100 of the present embodiment is not significantly different from the shape of the existing packaging box with a head, and the amount of the blank 101 used and the workload and complexity in the assembling process using the blank 101 are not significantly increased. Therefore, the packaging box 100 of the present embodiment can be produced as stably as the existing packaging box with a head.

[0109] In addition, according to the packaging box 100 of the present embodiment, the second side wall 21 includes an opening start portion 26, and the lid portion 25 of the first side wall 20 is opened starting from the second side wall 21. As a result, the box can be easily opened and will not be significantly deformed after being opened. This also makes it easy to re-close the box.

[0110] In addition, according to the packaging box 100 of the present embodiment, the pair of left and right first breaking lines 4 are perforation lines, and the second portions 42, which are one end portions of the respective incisions 40 constituting the perforation lines, are bent toward the left and right side edges of the first side wall 20 and the left and right side edges of the first head piece 11. Therefore, according to the packaging box 100 of the present embodiment, as Figure 4As shown, when the lid portion 25 of the first side wall 20 and the separation portion 13 of the first head piece 11 are torn off, a plurality of ridge-like protrusions 14 are formed on the lid portion 25 side and the separation portion 13 side. Therefore, when the article accommodated in the box body 1 is taken out through the opening 27, the user's hand does not come into contact with the protrusions 14, so the user does not feel pain or the like.

[0111] <Variant Example>

[0112] The above has described one embodiment of the packaging box of the present invention. However, the packaging box of the present invention is not limited to the above embodiment, and various deformations can be made without departing from the gist of the present invention. For example, the following deformations are possible. The gist of the following deformations can be appropriately combined.

[0113] In the above embodiment, the second breaking line 5 is formed on the second side wall 21 and is opened starting from the opening starting portion 26 of the second side wall 21, so as to open the lid portion 25 of the first side wall 20. On the other hand, a variant example can be configured such that the second breaking line 5 is not formed on the second side wall 21, and the lid portion 25 is opened starting from the lid portion 25 of the first side wall 20, so as to open the lid portion 25.

[0114] In the above embodiment, each closing portion 3 is composed of four flaps 30 - 33. However, the structure of the closing portion 3 is not particularly limited. There are also no particular limitations on the number and shape of the flaps, as long as the two ends of the main body portion 2 of the box body 1 can be closed.

[0115] The above embodiment is configured such that the second head piece 12 is connected to the upper edge of the first head piece 11, and the second head piece 12 is folded back toward the first head piece 11 so that the first head piece 11 and the second head piece 12 overlap each other. On the contrary, a variant example can be configured such that the second head piece 12 is not connected to the upper edge of the first head piece 11, and the first head piece 11 and the second head piece 12 are overlapped with each other by attaching the first head piece 11 to the second head piece 12 at a portion other than the separation portion 13.

[0116] The above embodiment is configured such that the main body portion 2 of the box body 1 has a cylindrical shape composed of a rear surface, a top surface, a front surface, and a bottom surface, and the left and right side surfaces are closing portions 3. On the contrary, a variant example can be configured such that the main body portion 2 of the box body 1 has a cylindrical shape composed of a rear surface, left and right side surfaces, and a front surface, and the top surface and the bottom surface are closing portions that close the openings at the ends of the main body portion 2.
