  However, when the cut line formed on the side surface of the packaging box is formed near the lower end of the side surface, when the packaging box is dropped, a part of the cut line may be broken. There was a problem that there was.

  In particular, in the carton of Patent Document 1, the line 25 is formed up to the vicinity of the end bent parts 21 and 22, and the carton in a state in which an object to be stored (can 31 in Patent Document 1) is stored is bent at the end. When dropped from a relatively high position with the portions 21 and 22 side down, the line 25 (particularly, the portion near the end bent portions 21 and 22 in the line 25) may be broken by the impact of the drop. There is.

  Also, in the packaging paper box of Patent Document 2, since the cutoff line 2 is formed near the side of the front plate 1, a paper box in a state in which an object to be stored (rolled paper paper a in Patent Document 2) is stored. When dropped from a relatively high position, the cutoff line 2 (particularly, the portion of the cutoff line 2 closer to the grounding surface when dropped) may be broken by the impact of the drop.

  Also, in the paper box 300 of Patent Document 3, when at least a part of the unsealing line 100 or the easy-cut line 21 is formed at a position close to the bottom surface portion 17, the paper box 300 in a state in which an article to be stored is stored. When dropping from a relatively high position with the bottom surface portion 17 side down, there is a possibility that the portion of the unsealing line 100 or the easy-to-cut line 21 close to the bottom surface portion 17 is broken.

  Therefore, the present invention provides a packaging box that can prevent breakage of the score line even when the packaging box in which a stored item is stored is dropped in the packaging box having a score line formed on the side surface. It is intended.

  The present invention has been created to solve the above-mentioned problems. First, a bottom surface (50) and a sleeve standing from each side of the bottom surface and substantially perpendicular to the bottom surface. A sleeve-like portion (5) having at least three or more side portions (10, 20, 30, 40) and a lid portion (120, 130) continuously provided from the upper end of the sleeve-like portion. The specific side surface portion in the specific side surface portion which is the packaging box and includes at least one side surface portion in the sleeve-shaped portion, including the corner portion on the bottom surface side of the specific side surface portion (KR11, KR12). Bending ruled lines (C11, C12) that are inclined with respect to the direction of the side part on the bottom surface side of the bottom side are formed. The first side part which is the side part and the other side part adjacent to the specific side part First side position (P11, P12) which is a midway position from one end of the first side to the other end, and one end of the second side Is formed in a direction between the first intermediate position and the second intermediate position at a position between the second intermediate position (Q11, Q12), which is an intermediate position from the first portion to the other end portion, and has a score line on the specific side surface portion. (K12) is provided, and the corner and the cut line in the corner region where the ruled line is formed are formed on opposite sides of the ruled line.

  In the first configuration, when the packaging box is dropped, a folding ruled line is provided, so that the specific side part is bent via the ruled line due to the impact of the drop, and the specific side part is bent via the ruled line. Since the impact of the fall is absorbed by bending, breakage of the score line can be prevented.

  Second, in the first configuration, the ruled line is a corner portion on the bottom surface portion side of the specific side surface portion, and is on the first adjacent side surface portion (20) side that is one side surface portion adjacent to the specific side surface portion. Are formed in each of a corner region (KR11) including the corner portion and a corner region (KR12) including a corner portion on the second adjacent side surface portion (30) side which is the other side surface portion adjacent to the specific side surface portion. It is characterized by.

  Thirdly, in the first or second configuration, the portion (K12d-2, K12d-3) facing the ruled line in the cut line is specified as going to the second side in the horizontal direction. It is formed so that the distance from the side part by the side of the bottom face part of a side part may become long. Therefore, the distance between the part of the score line facing the ruled line and the ruled line can be ensured as long as possible, and the influence when the specific side part is bent through the ruled line by dropping the packaging box is reduced. It is possible to prevent breakage of the score line.

  Fourth, in the second configuration, the score line is formed in a circumferential shape in the specific side surface portion, and the bottom surface side score line (K12d) formed on the bottom surface side of the score line is the lateral direction. Formed from the bottom side first cut line (K12d-1) and the end of the first cut side on the first adjacent side surface side, and as it goes to the first adjacent side surface side, Formed from the bottom face side second cut line (K12d-2) formed so that the distance from the side part on the bottom face side becomes long, and the end part on the second adjacent side face side of the first cut line, 2 The bottom face side third cut line (K12d-3) formed so that the distance from the side part on the bottom face side of the specific side face portion becomes longer as going to the adjacent side face side. To do.

  Therefore, the distance between the second cut line and the ruled line can be ensured as long as possible, and the distance between the third cut line and the ruled line can be ensured as long as possible. The influence when the specific side surface portion bends through can be reduced, and breakage of the score line can be prevented.

  Fifth, in the fourth configuration, the second cut line and the third cut line are formed in a straight line. Therefore, it is possible to ensure a long distance from the ruled line as compared to the case where the second cut line and the third cut line are in an arc shape in which the second cut line and the third cut line bulge obliquely downward.

  Sixthly, in the fourth or fifth configuration, the cut line is continuously provided from an end of the second cut line opposite to the first cut line, and the first adjacent side surface of the specific side surface portion. The first adjacent side face side cut line (K12b) formed substantially parallel to the side part of the part side and the end part on the opposite side to the first cut line of the third cut line, A second adjacent side surface side cut line (K12c) formed substantially parallel to a side portion on the second adjacent side surface side, and an end portion opposite to the second cut line of the first adjacent side surface side cut line; And an upper cut line (K12a) formed between the ends of the second adjacent side face side cut line opposite to the third cut line.

  Seventhly, in any one of the first to sixth configurations, in one corner region, the length from the corner in the corner region to the first intermediate position and the corner in the corner region To the second halfway position is substantially the same. Therefore, since the ruled line is approximately 45 degrees with respect to the side portion on the bottom surface portion side of the specific side surface portion, the impact can be effectively absorbed.

Eighth, in any of the first to seventh configurations, the score line is parallel to the ruled line, and is opposite to the corner of the corner region where the ruled line is formed across the ruled line. Formed on the opposite side of the corner from the virtual line (J11, J12),

That is, the ruled line C11 may be formed in a direction connecting the midway position P11 and the midway position Q11 at a position between the midway position P11 and the midway position Q11 (may be “linearly formed”).

  Note that the cut line K12 (particularly, the cut line K12d) is formed on the opposite side to the corner R11 in the corner region KR11 where the ruled line C11 is formed with the ruled line C11 interposed therebetween.

  Further, the ruled line (second ruled line) C12 is a midway position (first midway position, third midway position) P12 to the front part 10 from the right side end of the lower side of the front part 10 to the left side end. Of the right side surface side (second side portion, third side portion) 10c is formed in a straight line from the lower end to the upper end position (second intermediate position, fourth intermediate position) Q12 of the front portion 10 It is formed to be inclined with respect to the lower side. Further, the length from the lower corner R12 to the midway position P12 on the right side of the front portion 10 and the length from the lower corner R12 to the midway position Q12 on the left side of the front portion 10 are substantially the same. The angle formed with respect to the lower side of the front portion 10 of the ruled line C12 is about 45 degrees. The ruled line C12 is formed in a corner region (second corner region) KR12, which is a region including the corner (second corner) R12 on the right side 30 on the bottom surface 50 side in the front portion 10.

Are the same (may be substantially the same), and the two distances are the shortest positions. The corner R12 is a region including the lower end of the front portion 10 and the position of the end portion on the right side (the end portion on the right side of the lower side 10d of the front portion 10 and the side portion on the right side of the front portion 10). It is good also as an area | region (tip area | region) including the lower end of 10c (area | region smaller than corner | angular area | region KR12).

Further, the lower corner portion R12 and the cut line K12d on the right side surface side of the front portion 10 are located on opposite sides of the ruled line C12.

  Further, the ruled line C12 may not be formed up to the midway position P12 or the midway position Q12, and the end of the ruled line C12 may be formed up to a midway position toward the midway position P12 (that is, the ruled line C12 An interval is formed between the end portion on the way position P12 side and the way position P12), and the end portion of the ruled line C12 may be formed to the way position toward the way position Q12 (that is, A space is formed between the end of the ruled line C12 on the middle position Q12 side and the middle position Q12). That is, the ruled line C12 may be formed at a position between the midway position P12 and the midway position Q12 in a direction connecting the midway position P12 and the midway position Q12 (may be “linearly formed”).

  The cut line K12 (particularly, the cut line K12d) is formed on the opposite side of the corner part R12 in the corner region KR12 where the ruled line C12 is formed with the ruled line C12 interposed therebetween.

  The ruled lines C11 and C12 are formed on the inner surface of the front portion 10, but may be formed on the outer surface.

  Further, the ruled lines C11 and C12 are separated from the cut line K10 (particularly, the cut line K12) by a predetermined distance in order to prevent the cut line K10 from breaking when the packaging box A storing the objects to be stored is dropped. They are separated from each other.

  That is, as shown in FIG. 11, the score line K10 is parallel to the ruled line C11 and is inside the virtual line J11 on the opposite side of the corner R11 across the ruled line C11 (from the corner R11 side and the ruled line C11 side). Similarly, the cut line K10 is parallel to the ruled line C12 and inside the virtual line J12 opposite to the corner part R12 across the ruled line C12 (on the corner part R12 side and the ruled line C12 side). Is formed on the opposite side.

  Here, the imaginary line J11 passes from the intersection W11a of the imaginary line (straight imaginary line) passing through the midway position P11 and parallel to the side portion 10b and the imaginary line (straight imaginary line) passing through the midway position Q11 and parallel to the lower side 10d. A perpendicular line to the ruled line C11 is provided, and passes through a midpoint of a virtual line (straight virtual line) connecting the intersection point W11b between the perpendicular line and the ruled line C11 and the intersection point W11a (an equidistant point between the intersection point W11a and the intersection point W11b) W11c. Are virtual lines parallel to the ruled line C11. In other words, the virtual line J11 is separated from the ruled line C11 through a half length from the intersection W11a to the ruled line C11.

  The virtual line J12 is a ruled line from the intersection W12a of the virtual line (straight virtual line) passing through the midway position P12 and parallel to the side part 10c and the virtual line (straight virtual line) passing through the midway position Q12 and parallel to the lower side 10d. A perpendicular line to C12 is provided, and passes through the midpoint of the virtual line (straight virtual line) connecting the intersection point W12b between the perpendicular line and the ruled line C12 and the intersection point W12a (the equidistant point between the intersection point W12a and the intersection point W12b) W12c. This is a virtual line parallel to the ruled line C12. That is, the imaginary line J12 is separated from the ruled line C12 through a half length from the intersection W12a to the ruled line C12.

  In this way, the score line K10 is formed at a predetermined distance from the ruled lines C11 and C12. Therefore, even if the packaging box A falls and the front part 10 is bent via the ruled line C11 or the ruled line C12, the score line K10. The breakage of (particularly the cut line K12) can be prevented more reliably.

  Further, in the packaging box A, the back surface portion 40 is provided with fold lines C42 and C43, the left side surface portion 20 is provided with a fold line C21, the right side surface portion 30 is provided with a fold line C31, and the glue margin 49 is bent. C49 is provided.

The upper end portion of the back surface portion 40 is located at the upper left corner of the back surface portion 40. Specifically, a ruled line for folding is formed on the inner surface of the back surface portion 40 along the broken line C42.

  Further, the fold line (second fold line) C43 is linearly formed obliquely upward from the position of the contact point between the cut line K41 and the cut line K45 toward the outer side (right side) in the lateral direction of the back surface portion 40, and the broken line C43. The upper end portion of the back surface portion 40 is located at the upper corner portion of the rear surface portion 40 on the right side surface side. Specifically, a folding ruled line is formed on the inner surface of the back surface portion 40 along the broken line C43.

And the length between the broken lines C43 is shortened. The ruled line formed along the broken line C42 is formed from the upper left corner of the back surface 40 to the cut line K40. However, the ruled line may be provided with a gap between the lower end of the ruled line and the cut line 40. Alternatively, a configuration may be adopted in which an interval is provided between the upper end of the ruled line and the corner portion of the upper left side of the back surface portion 40. That is, the middle position (third middle position) from the left side edge of the cut line K40 to the right side edge (the third corner), which is the upper corner of the left side of the back surface 40 (third corner). Specifically, it may be formed in a direction connecting the third corner and the fifth intermediate position at a position between the cut line K41 and the cut line K44.

  Similarly, the ruled line formed along the broken line C43 is formed from the corner of the upper right side of the back surface 40 to the cut line K40, but there is a gap between the lower end of the ruled line and the cut line 40. The structure which provides may be sufficient, and the structure which provides a space | interval between the upper end of this ruled line and the corner | angular part of the right side surface side upper end of the back surface part 40 may be sufficient. That is, it is a corner part at the upper end on the right side surface of the back surface part 40 (fourth corner part) and a middle position from the right side edge part to the left side edge part of the cut line K40 than the fifth middle position. Formed in the direction connecting the fourth corner and the sixth intermediate position at a position between the middle position on the right side (sixth middle position) (specifically, the position of the contact point between the score line K41 and the score line K45). It only has to be done.

  Further, the broken line (third broken line) C21 is linearly formed obliquely upward from the midway position of the cut line K24 (that is, midway from the back end to the front end) toward the back. The upper end portion of the broken line C21 is positioned at the upper corner portion of the left side surface portion 20 on the back surface. In other words, the polygonal line C21 is formed from the corner at the upper end on the back side of the left side surface part 20 toward the middle position of the score line K24. Specifically, a ruled line for bending is formed on the inner surface of the left side surface portion 20 along the broken line C21. One end of the ruled line is located at the upper corner (fifth corner) of the back side of the left side 20 and the other end of the ruled line is at the midpoint (seventh midpoint) of the cut line K24.

(That is, an interval is formed between the end of the ruled line on the corner side and the corner), and the end of the ruled line is in the middle of the cut line K24. (That is, a gap is formed between the end portion on the middle position side of the score line K24 and the middle position of the score line K24). That is, the ruled line (which may be the broken line C21) is located between the upper corner of the left side 20 and the middle of the cut line K24, and between the upper corner of the left side 20 and the score K24. What is necessary is just to be formed linearly in the direction which connects a position.

  The broken line (fourth broken line) C31 is linearly formed obliquely upward from the midway position of the score line K34 (that is, midway from the back side end to the front side end) toward the back side. The upper end portion of the broken line C31 is located at the upper corner portion of the back surface of the right side surface portion 30. That is, the polygonal line C31 is formed from the corner at the upper end on the back surface side of the right side surface portion 30 toward the midway position of the score line K24. Specifically, a ruled line for folding is formed on the inner surface of the right side surface portion 30 along the broken line C31. One end of the ruled line is located at the upper corner (sixth corner) of the back side of the right side part 30, and the other end of the ruled line is located at the midway position (eighth midway position) of the cut line K34.

(That is, an interval is formed between the corner side end of the ruled line and the corner), and the end of the ruled line is in the middle of the cut line K34. (That is, a gap is formed between the end portion on the middle position side of the score line K34 and the middle position of the score line K34). That is, the ruled line (which may be the broken line C31) is located between the upper corner of the right side 30 and the middle of the cut line K34, and between the upper corner of the right side 30 and the score K34. What is necessary is just to be formed linearly in the direction which connects a position.

Thereafter, the flap portions 120 and 130 are bent inward and the lid portions 110 and 140 are bent inward to close the lid portions 110 and 140, and the adhesive tape T is passed from the left side surface portion 20 through the upper surface to the right side surface portion. By bonding up to 30, the state shown in FIG. That is, in the state shown in FIG. 12, the lid portions 110 and 140 are fixed in a closed state.

  When the objects to be stored are packaged in the packaging box A with the lids 110 and 140 closed as described above, the packaging box A storing the objects to be stored G is transported to a place where the objects to be stored A are displayed.

  Even when the packaging box A is dropped during transport of the packaging box A that stores the items to be stored, the ruled lines C11 and C12 are provided on the front face 10 so that the impact of the drop passes through the ruled lines C11 and C12. The front portion 10 is bent and the front portion 10 is bent via the ruled lines C11 and C12 (the ruled lines C11 and C12 are mountain-folded when viewed from the outside), so that the impact of the fall is absorbed. Breakage of the cut line K12 formed in a shape (particularly, the cut line K12d close to the bottom surface side among the cut lines K12) can be prevented. Since the ruled lines C11 and C12 are formed on the inner surface of the front part 10, the front part 10 is likely to be mountain-folded when viewed from the outside via the ruled lines C11 and C12.

  Depending on the manner of dropping, the front part 10 may be bent through two ruled lines of the ruled line C11 and the ruled line C12, or the front part 10 may be bent through one of the two ruled lines. That is, for example, when falling with the lower corner R11 on the left side, the front part 10 is bent through the ruled line C11, and the lower corner R12 is on the lower side on the right side. When falling, the front part 10 is bent through the ruled line C12. When the corner part R11 and the corner part R12 are dropped at the same height, the front part 10 is bent through the ruled line C11 and the ruled line 12. .

  That is, when the weight of the object to be stored is heavy, if the ruled lines C11 and C12 are not provided, a drop impact may be directly transmitted to the cut line K12, and the cut line K12d may be broken. Since there are ruled lines C11 and C12, there is no such fear.

  Further, no ruled line is formed in the corner region that is the region including the corner on the front surface 10 side on the bottom surface 50 side in the left side surface portion 20 (for example, in the expanded state of the packaging box A, the broken line C20 is The ruled line that is symmetrical with the ruled line C11 is not provided), and no ruled line is formed in the corner area that is the area including the corner on the front face 10 side on the bottom face 50 side of the right side face 30. (For example, in the unfolded state of the packaging box A, a ruled line that is line-symmetric with the ruled line C12 is not provided via the broken line C30), and is a region including a corner on the front face 10 side in the first piece 160. No ruled line is formed in the corner region (that is, the corner region on the left side surface 20 side and the corner region on the right side surface 30 side) (for example, the lower side of the front part 10 in the unfolded state of the packaging box A) Rule line symmetrical to ruled line C11 through And lines C12 and axially symmetrical borders is not provided), thereby, corners and lines C12 which borders C11 is provided it is possible to maintain the strength of the corner portions provided.

  That is, when the above-mentioned ruled lines are provided in the corner regions of the left side surface portion 20, the right side surface portion 30, and the first piece portion 160 in addition to the ruled lines C11 and C12, the corner portion (the corner composed of three surfaces) is caused by an impact. Part) is easy to bend, but conversely, since the corner part is easy to bend, there is a problem that the cut line K12 is easily broken. In the case of the present embodiment, the bottom face part 50 side of the front part 10 is present. Since the ruled lines are formed only at the corners, there is no such problem.

  In the display place of the packaging box A, by removing the opening lid portion 14 from the front portion 10, as shown in FIG. 13, it is possible to check the stored items that can be stored. it can.

  That is, the push portion 18 is pushed to break the cut line K14, and the cut line K14 is broken to put a finger into the semicircular cutout formed at the upper end of the opening lid main body 16, thereby opening the opening lid main body 16 By pulling the upper end region to the lower front side, the cut line K12 breaks (the cut line K12a breaks, then the cut lines K12b, 12c break, and then the cut line K12d breaks), The opening lid main body 16 is removed. When the pushing part 18 is connected to the frame-like part 12, the cut line (a part of the cut line K12a) between the pushing part 18 and the frame-like part 12 is broken and the pushing part 18 is removed.

  As described above, by removing the opening lid part 14 from the front part 10, a part of the front part 10 is opened to form the opening part 19, and an object to be stored stored inside the packaging box A is confirmed. can do. In this way, as a usage mode in the state where the stored item can be confirmed, for example, in a state where a plurality of packaging boxes storing the stored items are stacked, the opening lid portion 14 is removed for the packaging box A other than the uppermost stage. Thus, the stored object to be stored can be confirmed by making the stored object checkable state.

  Next, in order to change the state of the stored items, the upper component A-2 of the packaging box A is removed as described below. In addition, the opening cover part 14 shall be removed beforehand.

  That is, the pressing portion 44 in the back surface portion 40 is pressed to rotate the pressing portion 44 inward via the broken line C41. That is, by pressing the pressing portion 44 inward, the cut line K41 is broken, and the pressing portion 44 rotates through the broken line C41. Then, a space for inserting a finger is formed below the central region 46, so that the finger of one hand is inserted below the central region 46 and the finger is hooked on the lower end of the central region 46.

  Thereafter, by pulling the lower end of the central region 46 outward, the left region 47 and the right region 48 are gradually pulled from the central region 46 side, and the cut lines K42 and K43 are broken. In a state where the lower end of the central region 46 is pulled outward, the broken lines C42 and C43 are mountain-folded when viewed from the outside. That is, the left region 47 bends inward with respect to the central region 46 via the polygonal line C42, and the right region 48 bends inward with respect to the central region 46 via the polygonal line C43. In particular, since the broken lines C42 and C43 are provided, the sides along the cut line K42 in the left region 47 and the sides along the cut line K43 in the right region 48 are easily inclined in the front-rear direction. Becomes easy.

  Thereafter, by further pulling the lower end of the central region 46 outward, the cut line K24-1 between the lower left side surface portion 22 and the back side region 27 in the cut line K24 is broken from the back side, and the cut line K34 is cut. The cut line K34-1 between the lower right side surface portion 32 and the back surface region 37 is broken from the back surface side (see FIG. 14).

  That is, by pulling the lower end of the central region 46 outward, the back side region 27 rotates inward via the polygonal line C21 and the lower left side surface portion 22 and the back side region 27 are about to be separated laterally. The back side area 37 rotates inwardly via the broken line C31, and the lower right side surface portion 32 and the back side area 37 are about to be separated in the lateral direction, and the cut lines K24-1 and K34-1 are broken. At that time, the back side region 27 is rotated inward via the broken line C21 (that is, the back side region 27 is bent inward via the broken line C21 with respect to the front side region 26), and the back side region 37 is Since it rotates inward via the polygonal line C31 (that is, the back side region 37 bends inward via the polygonal line C21 with respect to the front side region 36), the polygonal line C21 and the polygonal line C31 are mountain-folded when viewed from the outside. It becomes the state of. In particular, since the broken lines C21 and C31 are provided, the back side regions 27 and 37 can be easily rotated via the broken lines C21 and C31, and the cut lines K24-1 and K34-1 can be easily broken.

  The cut lines K42 and K43 and the cut lines K24-1 and K34-1 are broken by pulling the lower end of the central region 46 outward. By the operation, it is possible to break the cut lines K42 and K43 to the cut lines K24-1 and K34-1 (up to the front end of the cut lines K24-1 and K34-1). That is, by pressing the pressing portion 44 that is a region between the pair of cut lines K44 and K46 in the lower back surface portion 42 from outside, a finger is hooked on the lower end of the central region 46, and the lower end of the central region 46 is pulled outward. The cut line K42 between the region 47 and the lower back surface part 42, the left side region 48, and the cut line K43 between the lower back surface part 42 are broken, and the back side region 27, which is a region on the back side with respect to the broken line C21 in the upper left side surface portion 25. Is turned inward via the broken line C21 to break the cut line K24-1 (the cut line between the back side region 27 and the lower left side part 22 in the cut line K24) and more than the broken line C31 in the upper right side part 35. The back side region 37, which is the back side region, rotates inwardly via the polygonal line C31, and forms a cut line K34-1 (the cut between the back side region 37 and the lower right side surface part 32 at the cut line K34). Line) is broken. As the order of breakage, the cut lines K42 and K43 are broken from the inside by pulling the lower end of the central region 46 outward, and then the cut lines K24-1 and K34-1 are broken from the back side.

  When the cut lines K24-1 and K34-1 are broken, the lower left side 22 and the rear side area are formed by further pulling the lower end of the central area 46 outward and pulling the central area 46 upward. 27 and the lower right side surface portion 32 and the back side region 37 are about to be separated from each other in the vertical direction, so that the cut lines K24-1 and K34-1 are broken. That is, since not only the horizontal separation operation but also the vertical separation operation can be obtained, the score lines K24-1 and K34-1 can be easily broken.

  Thereafter, as shown in FIG. 15, by pulling up the hand having the central region 46, the score lines K24 and K34 are broken toward the front side. That is, a cut line K24-2 between the lower left side surface portion 22 and the front side region 26 in the cut line K24, and a cut line K34-2 between the lower right side portion 32 and the front side region 36 in the cut line K34. It breaks to the end position on the front side. In that case, as shown in FIG. 15, it is preferable to make the state which pressed the location of the back side of lower structure part A-1 with the other hand. That is, when pressing with the left hand, as shown in FIG. 15, when pressing the upper ends of the corners of the lower back surface portion 42 and the lower left side surface portion 22 and pressing with the right hand (in this case, the central region 46 is pulled up with the left hand). The upper ends of the corners of the lower back surface portion 42 and the lower right surface portion 32 are pressed.

  The cut line K24 includes a cut line K24-1 and a cut line K24-2, and the cut line K34 includes a cut line K34-1 and a cut line K34-2.

  When the cut lines K24, K34 are fractured to the front side, the cut lines K24, K34 are inclined with respect to the horizontal direction so that the cut lines K24, K34 become upward as they go to the front side. K34 can be easily broken. That is, since the score lines K24 and K34 are formed upward toward the front side, the score lines K24 and K34 can be broken by the operation of lifting the back end of the upper component A-2, and the upper component A -2 lifting the end on the back side makes it easier to apply force, and the direction of the force applied to the breakage is greater than the direction perpendicular to the breakage direction of the cut line (the direction along the cut line breaks. Since the angle between the direction of the force applied to the broken portion and the breaking direction is an acute angle, the score line can be more easily broken. That is, assuming that the direction of the force F applied to the broken portion is the vertical direction (perpendicular to the horizontal direction) (the central region 46 is pulled upward, the direction of the force F applied to the broken portion is vertical (perpendicular to the horizontal direction). The angle α formed between the direction of the force F applied to the fracture location and the fracture direction is an acute angle, and as shown in FIG. 18A, the force F applied to the fracture location is a component F1 perpendicular to the fracture direction. And the component F2 in the breaking direction, and not only the component F1 but also the component F2 is present, so that the breakage is facilitated. Compared with this case, when the direction of the score line is the horizontal direction, as shown in FIG. 18B, the angle α formed by the direction of the force F applied to the broken portion and the breaking direction is a right angle, and the breaking direction Since there is no force component in the direction of breaking, there is no force component perpendicular to the direction of breaking, making it difficult to break compared to the case of FIG. When the direction of the score line is lowered toward the breaking direction, the angle α formed by the direction of the force F applied to the broken portion and the breaking direction becomes an obtuse angle as shown in FIG. Since the force F applied to the location is divided into a component F1 in a direction perpendicular to the breaking direction and a component F2 in the direction opposite to the breaking direction, it is more difficult to break compared to the case of FIG. In FIG. 18, the score line is schematically shown by a straight line.

  The arrangement direction of the plurality of cuts 210 on the cut line K42 is inclined obliquely upward so as to become an upper side from the cut line K41 side toward the left side end part (cut line K24 side) of the back surface part 40. The disposition direction of the plurality of cuts 220 along the cut line K43 is inclined obliquely upward so as to become upward as it goes from the cut line K41 side to the right side end portion of the back surface part 40. It can be said that it is easy to break for the same reason as in the case of the line of sight K24, K34. That is, by pulling the lower end of the central region 46 outward, the central region 46 rotates about the upper side of the back surface portion 40. Therefore, the lower end of the central region 46 is pulled upward in the vertical direction. Is pulled upward, the lower ends of the left region 47 and the right region 48 are also pulled upward, but the direction of the force applied to the fractured portion is greater than the direction perpendicular to the fracture direction of the score line (along the score line). (The direction to the side to break) in the direction of breakage (the angle formed by the direction of the force applied to the breakage point and the breakage direction is an acute angle), so that the score line can be more easily broken.

  After breaking up to the front end position of the score lines K24, K34, the upper component A-2 moves the front end position of the score lines K22, K32 by pulling the central region 46 obliquely upward. Since the cut lines K22 and K32 are broken while rotating to the center, the cut lines K15 and K16 are broken by further pulling the upper component A-2 further to the front side (or the lower front side). The upper component A-2 is separated from the lower component A-1.

  The state in which the upper component A-2 is removed is as shown in FIGS. 16 and 17, and the object G is stored in the lower component A-1, so in this state, Display object G. As described above, the stored object display state can be changed to the stored object display state. The state shown in FIGS. 16 and 17 is the storage object display state.

  In addition, since the lower front part 12a is formed in the substantially U shape and the part except left and right sides is formed low, it becomes easy to visually recognize the to-be-contained object G from the front side. Moreover, since the upper side of the lower component part A-1 is open, when the storage object G is taken out, the storage object G may be pulled out and taken out.

  In the above description, it has been described that the upper component A-2 is removed in a state where the opening lid 14 is removed from the front surface portion 10, but the upper side in a state where the opening lid portion 14 is provided on the front surface portion 10. You may make it remove the structure part A-2 and the opening cover part 14. FIG.

  In that case, the same operation as the above-described operation for removing the upper constituent part A-2 is performed, and in the front part 10, when the cut lines K15 and K16 are broken as described above, the upper constituent part A-2 is further in front. By pulling to the side (or the front lower side), the part below the cut line K15 of the cut line K12b, the part below the cut line K16 of the cut line K12c, and the cut line K12d are broken. The upper component A-2 and the opening lid 14 are removed. In this case, the portion of the front portion 10 above the cut line K15 of the cut line K12b, the portion above the cut line K16 of the cut line K12c, and the cut line K12a are not broken.

  In the packaging box A, the upper component A-2 is removed, and the belt-like zipper is not removed. Therefore, the belt-like zipper is not generated as waste, and only the upper component A-2 is discarded. That's fine. That is, in the case of a configuration in which two parallel cut lines are formed in a circumferential shape and a belt-like zipper is provided, two wastes are generated: the upper portion of the zipper and the zipper itself. In some cases, the waste may be only the upper component A-2.

  As described above, according to the packaging box A of the present embodiment, the ruled lines C11 and C12 are provided. Therefore, even if the packaging box A storing the objects to be stored is dropped, the score line K12 (particularly, the score line K12d). ) Will not break.

  Moreover, since the space which puts a finger into the lower side of the center area | region 46 is formed by pushing the holding | suppressing part 44, when removing the upper structure part A-2 of the packaging box A, operation which hooks a finger first is easy. Can be done.

  Moreover, since the broken lines C42 and C43 are provided as described above, the cut lines K42 and K43 are easily broken, and the broken lines C21 and C31 are provided. Therefore, the cut lines K24-1 and K34-1 are provided. Can be easily broken, and the cut lines K42 and K43 to the cut lines K24-1 and K34-1 can be broken by one operation of pulling the lower end of the central region 46 outward. Further, since the cut lines K24 and K34 are formed to be inclined with respect to the horizontal direction so as to become higher as going to the front side, the cut lines K24 and K34 can be easily broken. As described above, it is possible to easily cut the score line after the operation of hooking the finger first.

  Although the angle of the ruled lines C11 and C12 with respect to the lower side of the front part 10 is approximately 45 degrees, the present invention is not limited to this, and the ruled line C11 is located on the left side of the front part below the front part 10. The ruled line C12 may be formed so as to be inclined with respect to the lower side of the front portion 10 at the corner on the right side surface under the front portion 10. Just do it.

  Further, the ruled lines C11 and C12 are provided at the lower corners of the front part 10, but they are also provided on other members (the left side part 20, the right side part 30, and the back part 40) in the sleeve-like part 5. It may be. That is, unlike the above example, when the cut line K5 is formed near the bottom surface portion 50, the packaging box A is dropped by forming a ruled line having the same structure as the ruled lines C11 and C12. In this case, breakage of the score line K5 can be prevented.

  In the above description, the cut line K24 is linearly formed so as to be upward as it goes from the back side to the front side. However, the curve line K24 is curved so as to be upward as it goes from the back side to the front side. (For example, it is formed in a circular arc shape so that the inclination angle increases toward the front side), and similarly, the cut line K34 becomes higher as it goes from the back side to the front side. Although it is formed in a straight line shape, it may be formed in a curved shape so as to be upward as it goes from the back side to the front side (for example, in an arc shape so that the inclination angle increases toward the front side) Form).

  In addition, although the cut line K24 is formed in a straight line shape, it may be bent at the boundary position between the cut line K24-1 and the cut line K24-2 (end position on the cut line K24 side of the broken line C21). In addition, the cut line K24-1 does not have to have a configuration in which the cut line K24-1 becomes higher from the back side to the front side. For example, the cut line K24-1 may be formed in the horizontal direction. Similarly, the cut line K34 is formed in a straight line, but is configured to be bent at the boundary position between the cut line K34-1 and the cut line K34-2 (end position of the broken line C31 on the cut line K34 side). In addition, the cut line K34-1 does not have to have a configuration in which the cut line K34-1 increases from the back side to the front side. For example, the cut line K34-1 may be formed in the horizontal direction. This point may be applied to the cut lines K24 'and K34' of the second embodiment.

  In addition, the cut lines K42 and K43 are formed so as to be inclined so as to be higher on the outer side of the back surface portion 40, but may be formed in a horizontal direction (a direction parallel to the lower side of the back surface portion 40). Good. This point may be applied to the cut lines K42 'and K43' of the second embodiment.

  Further, the cut line K20 has a cut line K22 and a cut line K24, but the cut line K24 may be extended to the front end of the left side surface portion 20 instead of the cut line K22. The cut line K30 has a cut line K32 and a cut line K34, but the cut line K34 may be extended to the front end of the right side surface 30 instead of the cut line K32. That is, the cut line K20 is formed so as to be higher from the rear side end part of the left side surface part 20 to the front side end part as it goes to the front side, and the cut line K30 is formed from the rear side end part of the right side part 30. You may make it form so that it may become an upper side, so that it goes to the front side to the edge part of a front side. In that case, the score lines K20 and K30 may be linear or curved.

  Further, in the above description, the sleeve-like portion 5 is connected to the right side portion 30, the front portion 10, the left side portion 20, and the back portion 40 in this order via a broken line, and the glue margin portion is provided between the right side portion 30 and the back portion 40. 49 is provided, but the present invention is not limited to this, and the position of the margin portion may be any position between adjacent members constituting the sleeve-like portion 5.

  In addition, the sleeve-like portion 5 has a configuration in which four members are sequentially connected via a broken line, but the invention is not limited thereto, and the sleeve-like portion 5 is continuously provided via a broken line from each side of the rectangular bottom surface portion. The members adjacent to each other constituting the sleeve-like portion may be connected to each other by an adhesive margin portion to form a sleeve shape as a whole.

  In the above description, the incision constituting the cut line K5 is mainly the substantially letter-shaped cut 210 and the notch 210 and the notch 220 which is line-symmetrical. It is good also as a shape cut.

  In the above description, the sleeve-like portion 5 is provided with four side portions (the front portion 10, the left side portion 20, the right side portion 30, and the back portion 40). However, the sleeve-like portion may be a sleeve-like shape having three or more side portions.
