  However, when the length between the cut line 1012a in the end wall 1001 and the upper side of the end wall 1001 becomes long, the auxiliary ruled line 1014 provided in the side wall 1002 becomes long, so that the end region 1002A-2 in the side wall 1002 becomes long. However, even if the upper end wall 1001A is pulled forward and the cut line 1012a is cut, it is difficult to cut the cut line 1012b.

  That is, the packaging box is usually formed of a corrugated cardboard material, but the corrugated cardboard material is a paper material and is flexible, so that the end region 1002A-2 is not sufficiently bent with respect to the upper side wall main body 1002A-1, and is simply The side wall 1002 is only slightly bent through the auxiliary ruled line 1014, and the cut line 1012b is difficult to cut.

  Therefore, the present invention is connected to the end wall by pulling the upper end wall, which is the upper region of the cut line formed laterally on the end wall, which is one side surface, to the outside and breaking the cut line. In a packaging box that is formed on the side wall and breaks the cut line continuously formed from the cut line of the end wall, even when the length between the cut line of the side wall and the upper side of the side wall is increased, the package box is formed on the side wall. An object of the present invention is to provide a packaging box that can easily break the score line.

The present invention was created to solve the above problems. First, a bottom surface (50) and a side surface standing from each side of the bottom surface and substantially perpendicular to the bottom surface. The side part (5) which consists of a front part (10), a left side part (20), a right side part (30, 31), and a back part (40), and the upper end of the side part A packaging box having a lid (120, 130), and a cut line (K5) is provided in a circumferential shape on the side surface, and the cut line is formed on the side on the right side and the left side on the front side. A first cut line (K10) formed between the side parts, and a second cut line (K30, K30 ′, K30 ″) formed between the front side part and the back side part in the right side part. , A third cut line (K20) formed between the front side and the back side of the left side, and the right side and left side of the back side 4th cut line (K40) formed between the parts, and in the back surface part, the fourth cut line is formed on the lower back surface part (42) which is an area below the fourth cut line on the back surface part. A pair of score lines (K44, K45) continuously provided from the upper back surface portion (45), which is an area above the fourth score line of the back surface portion, is provided on the right side surface side of the upper back surface portion. 1st intermediate position (P4) which is a middle position from the lower end (the lower end which is the position of the fourth cut line) to the upper end and the end on the left side from the end on the right side of the upper side of the back surface A first broken line (C45) is formed in a direction connecting the first intermediate position and the second intermediate position at a position between the second intermediate positions (P6, P5 ′), which is an intermediate position until the left side of the upper back surface portion. A third position that is an intermediate position from the lower end (or the lower end that is the position of the fourth cut line) to the upper end of the side portion on the surface side. The middle position (P3) and the fourth middle position, which is a middle position from the left side edge of the upper side of the back surface to the right side edge, are located on the left side of the second middle position or A second broken line (C44) is formed at a position between the fourth intermediate position (P5, P5 ′) overlapping the second intermediate position in a direction connecting the third intermediate position and the fourth intermediate position, The distance between the two folding lines is formed such that the length between the first folding line and the second folding line becomes longer as it goes to the fourth cut line side, and the upper back surface is an area above the first folding line. An area (48R), an upper left area (48L) which is an area above the second fold line, and an upper back surface body (45-1) which is an area below the first fold line and the second fold line. In the right surface portion, the upper right surface portion (35, 35 ') that is the region above the second cut line of the right surface portion The fifth intermediate position (P4 ″, P4 ′) that overlaps the first intermediate position at the intermediate position from the lower end (the lower end that is the position of the second cut line) to the upper end of the side portion on the back side of the upper right surface portion. ) And the sixth intermediate position (P12), which is an intermediate position from the rear end of the second cut line to the front end, in a direction connecting the fifth intermediate position and the sixth intermediate position. A third broken line (C31, C31 ′) is formed, the third broken line is formed so as to be on the front side as it goes down, and the left surface portion is an area above the third cut line on the left surface portion. The upper left surface portion (25) has a seventh intermediate position that overlaps the third intermediate position at the intermediate position from the lower end of the side on the back side of the upper left surface portion (may be the lower end that is the position of the third cut line) to the upper end. Position (P3 ′) and the eighth halfway which is the middle position from the back side end to the front side end of the third cut line A fourth broken line (C21) is formed at a position between the positions (P11) in a direction connecting the seventh intermediate position and the eighth intermediate position, and the fourth broken line is formed so as to be on the front side as it goes downward. Then, by pushing the region between the pair of cut lines in the lower back surface portion from the outside, hooking a finger to the lower end of the upper back surface body, and pulling the lower end of the upper back surface body outward, the upper back surface body is a second fold line. And the upper back main body bulges outward through the fourth fold line, the fourth cut line breaks, and the first back side area (the back side area from the third fold line in the upper right side section) ( 37) is rotated inward via the third broken line, and the lower right surface portion (32, 32 ') which is a region below the first back side region and the second cut line of the right surface portion in the second cut line. The score line in between breaks, and in the region on the back side of the fourth broken line in the upper left surface part The second back side region (27) is turned inward through the fourth broken line, and the lower left side is a region below the second back side region and the third cut line of the left surface part in the third cut line. The cut line between the surface portions (22) is broken.

  In the packaging box of the first configuration, since the upper end of the third broken line is the fifth intermediate position and the upper end of the fourth bent line is the seventh intermediate position, the length of the third bent line or the fourth bent line is set to the broken line. Compared with the case where it is provided between the sixth middle position and the upper corner of the right surface portion or between the eighth middle position and the upper corner of the left surface portion, it can be shortened. And the fourth broken line bends, so that the break line between the first back side region and the lower right surface part in the second cut line and the cut line between the second back side area and the lower left surface part in the third cut line is broken. Can be easy.

  Further, since the first midway position and the fifth midway position coincide with each other, and the first fold line and the third fold line (or their extension lines) are in contact with each other at the midway position, the upper back surface body swells outward. As a result, the first back side region smoothly rotates, and the break of the cut line between the first back side region and the lower right surface part at the second cut line is facilitated. Since the second line and the 43 line (or their extension lines) are in contact with each other at the midpoint position, the second back line area smoothly swells when the upper back body bulges outward. Is turned, and the break of the cut line between the second back side region and the lower left surface part in the third cut line becomes easy.

  In the present invention, the upper end wall, which is the upper region of the cut line formed in the lateral direction on the end wall that is one side surface, is pulled outward to break the cut line, thereby being connected to the end wall. In a packaging box that is formed on the side wall and breaks the cut line continuously formed from the cut line of the end wall, even if the length between the cut line of the side wall and the upper side of the side wall is increased, the cut formed on the side wall The object of providing a packaging box that can easily break the line of sight was achieved as follows.

  The packaging box A1 based on this invention is comprised as FIG. 1-9 shows, and has the sleeve-like part 5, the bottom face part 50, the cover parts 110 and 140, and the flap parts 120 and 130. Yes.

  Here, the sleeve-like portion (side surface portion) 5 includes a front surface portion 10, a left side surface portion (left surface portion) 20 provided continuously from a side portion on the left side surface side of the front surface portion 10 via a broken line C <b> 20, and the front surface portion 10. Of the right side surface side of the right side surface side of the rear side portion of the left side surface portion 20 through the polygonal line C40. It has a paste margin part 49 provided continuously from a side part on the right side through a broken line C48. The broken line C20, the broken line C30, the broken line C40, and the broken line C48 are parallel to each other. In addition, a ruled line for folding is formed on the inner surface of the packaging box A1 along the broken lines C20, C30, C40, C48 (that is, the folded lines C20, C30, C40, C48 are for folding). It is formed by ruled lines.)

  The packaging box A1 is formed of a single sheet-like blank (specifically, cardboard (particularly double-sided cardboard), which may be cardboard, etc.). In addition, the direction of the step of the core in the double-faced cardboard is the direction shown in FIG. 6 (FIG. 20 for the packaging box A2 of Example 2 and FIG. 31 for the packaging box A3 of Example 3) (folded line C20). , A direction parallel to C30 and C40) (the direction of the center step may be another direction).

  The front part 10, the left side part 20, the right side part 30, and the back part 40 have a rectangular shape (specifically, a rectangular flat plate shape), and the front part 10 and the back part 40 have a vertically long rectangular shape. Yes.

  The longitudinal lengths of the front portion 10, the left side surface portion 20, the right side surface portion 30, and the back surface portion 40 are substantially the same.

  Further, in the lateral direction, the front surface portion 10 and the rear surface portion 40 are formed to have the same length, and the left side surface portion 20 and the right side surface portion 30 are formed to have substantially the same length (specifically, the right side portion 20 The horizontal length of the surface portion 30 is slightly smaller than the horizontal length of the left side surface portion 20).

  The margin portion 49 is formed in a substantially trapezoidal shape and is bonded to the outer surface of the end region on the back surface side of the right side surface portion 30. The glue margin 49 may be bonded to the inner surface of the end region on the back surface side of the right side surface portion 30. Since the margin part 49 is bonded to the right side part 30, it can be said that the right side part 30 and the margin part 49 constitute the right side part 31 of the packaging box A1. That is, the right side surface portion 30 can be the right side surface portion, and the right side surface portion 30 and the glue margin portion 49 can be configured as the right side surface portion.

  A cutout portion KV is formed at the position of the cut line K30 in the side portion on the back side of the right side portion 30 (which may be an end portion on the back side). That is, the notch KV has a substantially V shape formed by two straight side portions, and is formed so that the distance between the two side portions decreases from the back side to the front side of the right side portion 30. Has been. The lateral length of the notch KV is the same as (or substantially the same as) the lateral length of the margin 49, and is at least equal to or smaller than the lateral length of the margin 49. The notch portion KV is covered with the adhesive margin 49. A cut line K34 is continuously provided from the front end (end portion on the front side) of the notch KV. By providing the cutout portion KV, when the cut line in the region where the adhesive margin 49 and the right side surface 30 overlap, only the cut line K49 of the adhesive margin 49 needs to be broken. Breaking is easy. In addition, since the glue margin part 49 is adhere | attached on the outer side of the right side part 30, an appearance does not worsen by providing the notch part KV.

  In addition, although the glue margin part 49 was continuously provided from the side part of the right side surface side of the back surface part 40, it is a left-right symmetric configuration (in the unfolded state of the packaging box A1) through the center plane in the front-rear direction. As a line-symmetric configuration in which the front and back sides are reversed, the adhesive margin 49 may be provided continuously from the side on the left side of the back surface 40 and bonded to the outer surface of the left side 20. In this case, when the left surface portion is constituted by the left side surface portion 20 and the glue margin portion, the left side surface portion 20 becomes the left surface portion main body. That is, the left side surface portion 20 can be the left side surface portion, and the left side surface portion can be constituted by the left side surface portion 20 and the adhesive margin bonded to the left side surface portion 20.

  Further, the glue margin 49 is continuously provided from the back surface portion 40, but is provided continuously from the back surface side end portion of the right side surface portion 30 and bonded to the right side surface end portion of the outer surface of the back surface portion 40. It is good also as a structure. In that case, a broken line that coincides with a part of the broken lines C43 and C45 is formed in the margin part, and a cut line that coincides with a part of the cut line K43 is formed, and the cut part (similar to the cut part KV). The notch portion of the configuration is provided at the end position of the cut line K43 of the back surface portion 40. In addition, even when the configuration is symmetrical with respect to the center plane in the front-rear direction, the glue margin portion is continuously provided from the side portion on the back side of the left side surface portion 20, and the left side surface side of the outer surface of the back surface portion 40. It is good also as a structure adhere | attached on the edge part. However, the back surface portion 40 is provided with polygonal lines C42, C43, C44, and C45 (particularly, the polygonal lines C44 and C45). In order to facilitate the bending through the polygonal lines, the adhesive margin portion is provided on the back surface. It is preferable that the configuration is continuous from the portion 40.

  The sleeve-like portion 5 is formed with a score line (may be a planned cutting line) K5. That is, the cut line K5 is formed in the cut line K10 formed in the front surface part 10, the cut line K20 formed in the left side part 20, the cut line K30 formed in the right side part 30, and the back part 40. It has a cut line K40 and a cut line K49 formed in the glue margin 49. The cut line K20 is formed continuously from the left side end of the cut line K16 in the cut line K10, and the cut line K30 is formed continuously from the right side end of the cut line K17 in the cut line K10. The cut line K40 is continuously formed from the rear side end of the cut line K20, and the cut line K49 is formed continuously from the right side end of the cut line K40. In addition, in the state where the glue margin part 49 is bonded to the right side surface part 30, since the end part on the back side of the cut line K30 and the cut line K49 overlap, the cut line K30 is the end part on the right side surface of the cut line K40. It can be said that it is formed continuously. The cut lines K10, K20, K30, and K40 are all formed by planned cutting lines. That is, the cut line K5 is provided with a cut line K10, a cut line K20, a cut line K30, and a cut line K40 in a circumferential shape (or a loop shape).

  The cuts constituting the cut line K5 are mainly formed by arranging substantially square-shaped cuts 210 or cuts 220 that are symmetrical with the cuts 210 in a line except for the cut lines K10, K11, and K12. The cut lines K10, K11, and K12 are formed by straight or curved cut lines along the cutting direction. The incisions 210 and 220 can be said to be incisions having a general shape on the score line, and the incisions 210 and 220 are formed so as to penetrate from one surface of the blank to the other surface.

  Here, the cut line K10 includes a cut line K11 formed in a straight line in the left-right direction in the lower region of the front portion 10, and a cut line formed in a substantially arc shape from the left side end of the cut line K11. K12, a cut line K13 formed in a substantially arc shape from the end of the right side of the cut line K11, and a straight line from the upper end of the cut line K12 in the vertical direction (the height direction may also be the same). , A cut line K15 formed linearly in the vertical direction from the upper end of the cut line K13, and a cut line K16 formed linearly obliquely upward on the left side from the upper end of the cut line K14. And a cut line K17 formed linearly diagonally upward from the upper end of the cut line K15 on the right side surface side. The cut line K11, the cut line K12, the cut line K13, the cut line K14, and the cut line K15 are substantially U-shaped as a whole.

  The cut line (third cut line) K20 has a cut line (third cut line sub-component) K22 and a cut line (third cut line main component) K24. The cut line K22 is cut. It is formed continuously from the left side end of the line of sight K15 (may be “continuously provided”, and the same applies to others), and becomes the upper side from the front side to the back side of the left side 20. The cut line K24 is formed continuously from the end on the back side of the cut line K22, and is formed in a lower direction as it goes to the back side.

  The cut lines K22 and K24 are formed by arranging a plurality of cuts 210 in a row at intervals.

  The arrangement direction of the plurality of cuts 210 along the cut line K22 is such that it is upward as it goes from the front side end of the left side surface part 20 to the back side (that is, in the horizontal direction (for example, the direction of the lower side of the left side part 20). Are formed in a straight line, and the disposing direction of the plurality of cuts 210 in the cut line K24 is such that the direction of the cut line K24 decreases from the back side end to the back side. It is formed in a straight line (that is, inclined obliquely downward). That is, the score line K24 is formed in a straight line so as to become higher as it goes from the back side to the front side (that is, inclined obliquely upward with respect to the horizontal direction). In addition, as an inclination angle with respect to the lower side of the left side surface portion 20, the cut line K22 is formed larger than the cut line K24, and the cut line K24 is gently upward from the back side to the front side, and the cut line K22. Is upward at a larger angle with respect to the horizontal direction than the score line K24 from the front side to the back side. The cut line K22 is formed from the front side end of the cut line K24 to the side part on the front side of the left side surface part 20, and is formed so as to be lower on the front side.

  The length L24 in the front-rear direction from the front end of the cut line K24 to the back end (the length in the direction of the lower side of the left side 20) is from the front end of the cut line K22 to the back side. The length in the front-rear direction to the end portion (the length in the direction of the lower side of the left side surface portion 20) L22 is formed (that is, the length L24 is from the rear side end portion of the left side surface portion 20 to the front side. It has a length more than half of the length L20 in the front-rear direction to the end). Specifically, the length L22 is set to 1/4 to 1/3 of the length L20 (that is, the length L24 is set to 2/3 to 3/4 of the length L20).

  In addition, the length in the front-rear direction of the cut line K24-1 (the length from the midway position P11 to the broken line C40) L24-1 between the lower left side surface portion 22 and the back side region 27 in the cut line K24 is a length L20. 1/3 (may be approximately 1/3). In other words, the length of the cut line K24-1 in the front-rear direction is a part of the cut line K20 other than the cut line K24-1 (that is, a cut line that is a part of the cut line K22 and the cut line K24 other than the cut line K24-1). The same as the half of the length in the front-rear direction (half of the length from the boundary position between the cut line K22 and the cut line K24 to the side part on the back side of the left side face part 20). It is also possible. That is, by setting the length L24-1 to 1/3 (may be approximately 1/3) of the length L20, the back side region 27 can be easily rotated with respect to the front side region 26, and the cut line K24 is obtained. −1 is easy to break. The cut line K24-1 is a part of the cut line K24 and is a contact point between the cut line K24 and the broken line C21 (when the broken line C21 is not in contact with the cut line K24, the cut line K24 is connected to the cut line K24 that is an extension of the broken line C21). From the contact point) to the end of the cut line K24 on the back side. The lower left side portion 22, the back side region 27, and the polygonal line C21 will be described later.

  In the unfolded state of the packaging box A1, the notches 210 are arranged in one straight line by the cut line K16 and the cut line K22.

  Further, the cut line (second cut line) K30 has a cut line (second cut line sub-component) K32 and a cut line (second cut line main component) K34, and the cut line K32 is cut. It is formed continuously from the end on the right side of the line of sight K16, and is formed in a direction upward from the side on the front side of the right side 30 to the back side. The cut line K34 is the back side of the cut line K32. It is formed continuously from the end of the head and is formed in a lower direction as it goes to the back side. That is, the cut line K30 is formed substantially symmetrically with the cut line K20 (left and right symmetrical except for the cutout portion KV), and is formed substantially line-symmetrically (excluding the cutout portion KV) in the unfolded state of the packaging box A1. Are line symmetrical). That is, the cut line K32 is formed symmetrically with the cut line K22, and the cut line K34 is formed substantially symmetrical with the cut line K24 (symmetrical except for the cutout portion KV).

  Note that, at the position where the notch KV is provided in the right side surface 30, the position of the front end (innermost) of the notch KV is the end on the back side of the right side surface 30, and in this sense, the cut line K 30 30 can be said to be formed between the front side end and the back side end. Further, the notch KV is regarded as a part of the third cut line (that is, the cut line K30 and the cutout KV constitute a cut line K30 ′ as the third cut line) and the cutout KV It can be said that the cut line K30 is formed between the front-side end portion and the back-side end portion of the right side surface 30 by setting the base end position to the end of the right side 30.

  Further, when the right surface portion 31 is configured by the right side surface portion 30 and the glue margin portion 49, the cut line K30 ″ as the third cut line may be configured by the cut line K30 and the cut line K49. .

  Further, the cut line K34 and the cutout portion KV may form a cut line K34 ′ as the third cut line main component portion, and the right side portion 30 and the adhesive margin portion 49 constitute the right side portion 31. In this case, the cut line K34 '' as the third cut line main component may be constituted by the cut line K34 and the cut line K49.

  The cut lines K32 and K34 are formed by arranging a plurality of cuts 220 in a row at intervals.

  The arrangement direction of the plurality of cuts 220 along the cut line K32 is formed in a straight line so as to be upward (that is, inclined obliquely upward) from the front end to the back side of the right side 30. The arrangement direction of the plurality of cuts 220 in the cut line K34 is formed in a straight line so as to become lower (that is, inclined obliquely downward) from the back side end of the cut line K32 toward the back side. Yes. That is, the score line K34 is formed in a straight line so as to be higher as it goes from the back side to the front side (that is, inclined obliquely upward). In addition, as an inclination angle with respect to the lower side of the right side surface portion 30, the cut line K32 is formed larger than the cut line K34, and the cut line K34 is gently upward from the back side toward the front side, and the cut line K32 Is upward at a larger angle with respect to the horizontal direction than the score line K34 from the front side to the back side. The cut line K32 is formed from the front side end of the cut line K34 to the side part on the front side of the right side part 30, and is formed so as to become lower as it goes to the front side.

  The length in the front-rear direction (the length in the direction of the lower side of the right side surface portion 30) L34 from the end on the front side of the cut line K34 to the end on the back side of the notch KV is the end on the front side of the cut line K32. Is longer than the length L32 in the front-rear direction (the length in the direction of the lower side of the right side surface 30) from the rear side end to the back side (that is, the length L34 is the end of the right side 30 on the back side. To a front end portion of the front-rear direction has a length that is more than half of the length L30). Specifically, the length L32 is set to 1/4 to 1/3 of the length L30 (that is, the length L34 is set to 2/3 to 3/4 of the length L30).

  The length in the front-rear direction from the front end of the cut line K34-1 between the lower right side surface portion 32 and the back side region 37 in the cut line K34 to the end on the back side of the notch KV (intermediate position) The length from P12 to the back side of the right side 30 is L34-1 ′ (the length from the midway position P12 to the back side of the right side 30) is 1/3 of the length L30 (substantially). It may be 1/3). That is, the length L34-1 ′ is a portion of the cut line K30 other than the cut line K34-1 (that is, the cut line K32 and the cut line K34-2 which is a part of the cut line K34 other than the cut line K34-1). The same as (half of the length from the boundary position between the cut line K32 and the cut line K34 to the side of the back side of the right side face 30) (which may be substantially the same). is there. That is, by setting the length L34-1 ′ to 1/3 (may be approximately 1/3) of the length L30, the back side region 37 can easily rotate with respect to the front side region 36, and the cut line K34-1 is easily broken. The cut line K34-1 is a part of the cut line K34, and is a contact point between the cut line K34 and the broken line C31 (if the broken line C31 is not in contact with the cut line K34, the cut line K31 is connected with the cut line K34 that is an extension of the broken line C31. From the contact point) to the end of the cut line K34 on the back side. The lower right side portion 32, the back side region 37, and the polygonal line C31 will be described later.

  Thereby, the length of the half or more in the front-back direction in the score lines K20 and K30 can be fractured by pulling the upper component A-2 upward.

  Note that, in the unfolded state of the packaging box A1, the cuts 220 are arranged in one straight line by the cut line K17 and the cut line K32.

  The cut line (fourth cut line) K40 includes a cut line K41 formed linearly in the left-right direction, a cut line K42 formed from the left side end of the cut line K41, and the cut line K41. And a cut line K43 formed from an end portion on the right side surface side.

And the disposing direction of the plurality of cuts 220 in the cut line K43 is such that the disposition direction of the plurality of cuts 220 increases from the cut line K41 side to the end portion on the right side surface side of the back surface part 40 (that is, diagonally). It is formed in a straight line (inclined upward). That is, the score lines K42 and K43 are formed so as to be inclined upward as they go to the outside of the back surface portion 40.

  The inclination angle of the cut line K42 with respect to the lower side of the back surface portion 40 is the same as (or substantially the same as) the inclination angle of the cut line K24 with respect to the lower side of the left side surface portion 20, and in the expanded state of the packaging box A1, The notches 210 are arranged in one straight line by the eye line K24 and the eye line K42. In addition, the inclination angle of the cut line K43 with respect to the lower side of the back surface portion 40 is the same as (or substantially the same as) the inclination angle of the cut line K34 with respect to the lower side of the right side surface portion 30. Therefore, since the inclination angle of the adjacent cut line is the same, it can be broken very smoothly from the cut line K42 to the cut line K24, and can be broken very smoothly from the cut line K43 to the cut line K34. .

  Further, the cut line K49 is formed in the glue margin 49, and is formed continuously from the end portion on the right side surface of the cut line K43, and the cut line K49 has a plurality of linear cuts with intervals.

The surface portion 30 itself does not overlap (that is, the cut line K49 does not overlap the cut line K34-1). When the length in the lateral direction (front-rear direction) of the notch KV is shorter than the length in the lateral direction of the glue margin 49, a part of the cut line K49 (a part on the tip side of the glue margin 49). Are overlapped with the end portion on the back side of the cut line K34-1 and overlapped.

  Further, a pair of cut lines K44 and K45 are formed on the left and right sides downward from the cut line K41. That is, the score line K44 is provided continuously from the vicinity of the left side of the score line K41 (may be the left side of the score line K41) and is directed downward (to the lower side of the back surface 40). The cut line K45 is formed continuously from the vicinity of the right side end of the cut line K41 (may be the right side end of the cut line K41) and directed downward ( It is formed in a direction perpendicular to the lower side of the back surface portion 40. The cut line K44 and the cut line K45 are formed to have the same length, are formed in parallel to each other, and both are formed by linear cuts (continuous cuts).

The ruled line is formed by a ruled line pressed from the inside of the blank. Note that the cut lines K44 and K45 may be formed by planned cutting lines instead of cutting. That is, the cut lines K44 and K45 may be formed by any of continuous cuts and scheduled cutting lines. Further, a space may be provided between the ruled line provided along the broken line C41 and the lower end of the cut line K44, or between the ruled line and the lower end of the cut line K45, that is, the ruled line (folded line along the broken line C41). C41) may be formed between the lower end of the cut line K44 and the lower end of the cut line K45 in a direction connecting the two lower ends.

  As described above, a continuous cut line K5-1 from the end of the cut line K42 on the cut line K41 side to the end of the cut line K14 through the cut line K20 is basically formed by the cut 210. Further, a continuous cut line K5-2 from the end of the cut line K43 to the cut line K41 side through the cut line K30 to the end of the cut line K15 on the cut line K13 side is formed by the cut 220.

Folding ruled lines are formed (that is, the bent lines C42, C43, C44, C45, C46, C21, C31, and C49 are formed by folding ruled lines), and the ruled lines are pressed from the inside of the blank. It is formed by the ruled lines. Note that the ruled lines along the broken lines C41, C42, C43, C44, C45, C46, C21, C31, and C49 are formed by stamping from the inside of the blank, so that each ruled line can be visually recognized inside the blank. Each ruled line is visible from the outside of the blank. In addition, it is good also as a structure which can hardly visually recognize each ruled line from the outer side of a blank.

  That is, the fold line (sixth fold line) C42 is connected to the cut line K41 and the cut line K40 of the cut line K44 on the left side of the pair of cut lines K44 and K45. From the position of the installation position) toward the outside (left side) in the lateral direction of the back surface portion 40, and is formed in a straight line obliquely upward with respect to the horizontal direction (the direction of the lower side and the upper side of the back surface portion 40). The lower end is at the contact point P1, and the upper end of the broken line C42 is a cut at the side HL on the left side of the back 40 (may be a broken line C40 between the back 40 and the left 20). It is at an intermediate position P3 from the position P7 of the eye line K5 (the lower end of the side on the left side of the upper back surface 45) to the upper end of the side HL (the upper end of the side on the left side of the upper back 45). The midway position P3 may be a midway position from the upper end of the side HL to the position P7 of the cut line K5. The midway position P3 is on the side portion HL and is located above the position P7 and below the upper end of the side portion HL. Specifically, the contact point P1 (the contact point P1 is a cut line (left cut line)). The length in the vertical direction between the upper position of K44 and the intermediate position P3 (the length between the height position of the intermediate position P3 and the height position of the contact point P1) (the length between the intermediate position P3 and the lower side of the back surface portion 40) Length obtained by subtracting the length between the contact P1 and the lower side of the back surface portion 40) L11, and the vertical length between the upper side of the back surface portion 40 and the midway position P3 (intermediate from the height of the upper side of the back surface portion 40) (The length obtained by subtracting the height of the position P3) (the length obtained by subtracting the length between the upper side of the back surface portion 40 and the lower side of the back surface portion 40 from the midway position P3 and the lower side of the back surface portion 40) L12 The positions are the same (may be substantially the same). Thereby, it can be said that the direction of the polygonal lines C42, C43, C44, and C45 is easily set to about 45 degrees with respect to the horizontal direction. The length L12 may be the length in the vertical direction between the upper end of the side portion on the left side surface (which may be the broken line C40) and the midway position P3. Further, the length L11 may be the length in the vertical direction between the position P7 and the midway position P3.

  The ruled line formed along the broken line C42 is formed from the contact point P1 to the midway position P3. However, a configuration may be adopted in which a space is provided between the lower end of the ruled line and the contact point P1. The structure which provides a space | interval between position P3 may be sufficient. That is, the ruled line (which may be the broken line C42) is connected to the contact point P1 (second continuous position) that is a continuous position with the cut line K40 of the left side cut line K44 in the pair of cut lines K44, K45. What is necessary is just to be formed in the direction which connects the contact P1 and the intermediate position P3 in the position between the intermediate positions P3.

  In addition, the broken line (fifth broken line) C43 is formed symmetrically with the broken line C42 (symmetric with respect to the vertical line between the broken line C43 and the broken line C42 (center line along the broken line C46)). The broken line C43 is from the position of the contact point P2 (the ninth middle position) between the score line K41 and the score line K45 (the position where the pair of score lines K44 and K45 are connected to the score line K40 of the right-side score line K45). It is linearly formed obliquely upward with respect to the horizontal direction toward the outside in the lateral direction (left side) of the back surface 40, and the lower end of the broken line C43 is at the contact point P2, and the upper side of the broken line C43 is The end portion is a position P8 (a side on the right side surface of the upper back surface portion 45) of the cut line K5 in the side portion HR (may be a fold line C48 between the back surface portion 40 and the glue margin portion 49) of the back surface portion 40. HR from the bottom of the part) Intermediate position up to the upper end (the upper end of the side portion of the right side of the upper back portion 45) also may) as a line C48 (first intermediate position) in P4. The midway position P4 may be a midway position from the upper end of the side portion HR to the position P8 of the cut line K5. The midway position P4 is on the side portion HR, above the position P8 and below the upper end of the side portion HR. Specifically, the contact point P2 (the contact point P2 is a cut line (right cut line) K45). Length between the middle position P4 and the height position of the contact point P2 (the length between the middle position P4 and the lower side of the back surface 40). L21 obtained by subtracting the length between the contact P2 and the lower side of the back surface portion 40) and the vertical length between the upper side of the back surface portion 40 and the midway position P4 (the midway position from the height of the upper side of the back surface portion 40) The length obtained by subtracting the height of P4) (the length obtained by subtracting the length between the upper side of the back surface portion 40 and the lower side of the back surface portion 40 from the intermediate position P3 and the lower side of the back surface portion 40) L22 is the same (It may be substantially the same). Thereby, it can be said that the direction of the polygonal lines C42, C43, C44, and C45 is easily set to about 45 degrees with respect to the horizontal direction. The length L22 may be the length in the up-down direction between the upper end of the side portion on the right side (may be a broken line C48) and the midway position P4. The length L21 is the same length (may be substantially the same) as the length L11, and the length L22 is the same length (may be substantially the same) as the length L12. Further, the contact P1 and the contact P2 are the same position in the vertical direction, and the position P7 and the position P8 are the same position in the vertical direction.

  The ruled line formed along the broken line C43 is formed from the contact point P2 to the midway position P4. However, a space may be provided between the lower end of the ruled line and the contact point P2, and the upper end of the ruled line and the midway point may be provided. The structure which provides a space | interval between position P4 may be sufficient. That is, the ruled line (which may be the broken line C43) is connected to the contact P2 (first continuous position) that is a continuous position with the cut line K40 of the right side cut line K45 in the pair of cut lines K44, K45. What is necessary is just to form in the direction which connects the contact P2 and the intermediate position P5 in the position between the intermediate positions P5.

  Further, the lower end of the broken line C42 (or an extended line thereof) is the contact P1, and the lower end of the broken line C43 (or the extended line thereof) is the contact P2. However, the present invention is not limited to this, and the cut line K40 is used instead of the contact P1. 10 is a midway position from the right side end to the left side end (that is, the contact P1 and the 10th midpoint are different positions on the cut line K40), and the contact P2. Instead of the ninth halfway position which is the middle position from the left side end to the right side end of the cut line K40 (that is, the contact point P2 and the ninth halfway position are different from each other on the cut line K40). The tenth intermediate position may be on the left side of the ninth intermediate position. That is, the polygonal line C42 is formed at a position between the tenth intermediate position and the intermediate position P3 in a direction connecting the tenth intermediate position and the intermediate position P3, and the broken line C43 is at a position between the ninth intermediate position and the intermediate position P4. It is only necessary to be formed in the direction connecting the ninth intermediate position and the intermediate position P4. For example, the contact P1 is on the inner side of the contact between the broken line C42 (or its extension line) and the cut line K40 (the tenth intermediate position), and the contact P2 is the contact between the broken line C43 (or its extension line) and the cut line K40 (the first line). (9 middle position) may be inside.

  Further, the broken line (second broken line) C44 is formed in a straight line from the midway position P3 toward the inner side (right side surface side) in the lateral direction of the back surface portion 40 obliquely upward with respect to the horizontal direction to the upper side of the back surface portion 40. The lower end of the broken line C44 is in the middle position P3, and the upper end of the broken line C44 is provided at the position P5 on the upper side of the back surface part 40.

  The ruled line formed along the broken line C44 is formed from the midway position P3 to the position P5. However, the ruled line may be configured to have a space between the lower end of the ruled line and the midway position P3. The structure which provides a space | interval between position P5 may be sufficient. That is, the ruled line (which may be a broken line C44) is located at the midway position P4 and the midway position (fourth midway position) from the left side edge of the upper side of the back surface 40 to the right side edge (specifically, the fourth halfway position). May be formed at a position between the positions P5) in a direction connecting the intermediate position P3 and the fourth intermediate position.

  The polygonal line (first polygonal line) C45 is formed symmetrically with the polygonal line C44 (symmetric with respect to the vertical line between the polygonal line C45 and the polygonal line C44 (centerline along the polygonal line C46)). The broken line C45 is formed in a straight line from the midway position P4 toward the inner side (left side surface) in the lateral direction of the back surface portion 40 obliquely upward to the upper side of the back surface portion 40 with respect to the horizontal direction, and the lower end of the broken line C45 is The upper end of the polygonal line C45 is located at the middle position C45, and the upper end of the broken line C45 is the position on the upper side of the back surface 40 (the middle position from the right side end to the left side end of the upper side of the back surface 40. 2 halfway position) P6.

  The ruled line formed along the broken line C45 is formed from the midway position P4 to the position P6. However, a configuration may be adopted in which a space is provided between the lower end of the ruled line and the midway position P4. The structure which provides a space | interval between position P6 may be sufficient. That is, the ruled line (which may be a broken line C45) is located at a midway position (second midway position) between the midway position P4 and the end on the right side of the upper side of the back surface 40 to the end on the left side. May be formed in a direction connecting the intermediate position P4 and the second intermediate position at a position between the positions P6).

  A broken line (seventh broken line) C46 is a position between the contact point P1 and the contact point P2 on the cut line K41, that is, a central position (first central position) P9 (the contact point P1 and the contact point P2 in the left-right direction of the cut line K41). The back surface in the direction perpendicular to the horizontal direction from the equidistant (possibly approximately equidistant position) (the direction parallel to the side HL on the left side and the side HR on the right side of the back 40). 40, the lower end of the broken line C46 is at the central position P9, and the upper end of the broken line C46 is the central position (second central position) P10. The central position P10 is located between the positions P5 and P6, and is equidistant from the positions P5 and P6, and from the end on the right side and the end on the left side of the upper side of the back portion 40, etc. It becomes the position of the distance. This central position P10 is the same position as the central position P9 in the left-right direction.

  The ruled line formed along the broken line C46 is formed from the central position P9 to the central position P10. However, a configuration may be adopted in which a space is provided between the lower end of the ruled line and the central position P9. A configuration may be adopted in which a gap is provided between the center position P10 and the center position P10. That is, the ruled line (may be a broken line C46) may be formed in a direction connecting the central position P9 and the central position P10 at a position between the central position P9 and the central position P10.

  As described above, in the back surface portion 40, the broken lines C42, C43, C44, and C45 are formed symmetrically with respect to the center line in the vertical direction.

  Further, the broken line (fourth broken line) C21 is an intermediate position P11 of the cut line K24 (that is, an intermediate position from the rear side end to the front side end of the cut line K24 (the intermediate position P11 is the cut line K20). It can also be said to be an intermediate position from the back side end to the front side end)) from the back side toward the back side, and is formed in a straight line obliquely upward with respect to the horizontal direction (the direction of the lower side and the upper side of the left side 20), The upper end of the polygonal line C21 is located at an intermediate position (seventh intermediate position) P3 ′. This intermediate position P3 ′ is the left side surface portion from the position P7 of the cut line K5 in the side on the back side of the left side surface portion 20 in the side portion on the back side of the left side surface portion 20 (the lower end of the side portion on the back side of the upper left side surface portion 25). 20 on the way to the upper end of the side on the back side (upper end of the side on the back side of the upper left side 25) (on the way from the lower end to the upper end of the side on the back side of the upper left side 25) (That is, the midway position P3 ′ is on the side on the back side of the upper left side surface part 25 and is above the position P7 and below the end on the back side of the upper left side part 25). The intermediate position P3 ′ overlaps the intermediate position P3 (may be coincident). The midway position P3 'may be a midway position from the upper end of the back side of the left side 20 to the position P7 of the cut line K5 in the back side of the left side 20. That is, the midway position P3 and the midway position P3 ′ are in a position that coincides in the vertical direction, the midway position P3 is a position on the left side of the back surface portion 40, and the midway position P3 ′ is the position of the left side surface portion 20. Although it is a position in the side part on the back side, the two side parts are in contact with each other via the polygonal line C40 (that is, the two side parts and the polygonal line C40 overlap (may be coincident), The intermediate position P3 and the intermediate position P3 ′ are overlapped, that is, the broken line C21 is formed from the intermediate position P3 ′ of the left side surface portion 20 toward the intermediate position of the cut line K24. The inclination angle with respect to the lower side direction of the left side surface portion 20 and the inclination angle with respect to the horizontal direction of the broken line C44 (for example, the lower side direction of the back surface portion 40) are the same (may be substantially the same), and the sleeve In the unfolded state of the portion 5, the polygonal line C21 and the polygonal line C44 are in one straight line shape (that is, they are formed on the same straight line), so that one of the polygonal line C21 and the polygonal line C44 is set in the horizontal direction. By setting the angle to about 45 degrees, the other side can be easily set to about 45 degrees with respect to the horizontal direction.

  One end of the ruled line formed along the broken line C21 is located at a midway position P3 ′, and the other end of the ruled line is located at a midway position P11 (eighth midway position) of the cut line K24. The ruled line may not be formed up to the midway position P3 ′ or the midway position P11 of the cut line K24, and the end of the ruled line may be formed up to a midway position toward the midway position P3 ′ (that is, A space is formed between the end of the ruled line on the middle position P3 ′ side and the middle position P3 ′), and the end of the ruled line is on the way to the middle position P11 of the cut line K24. (That is, a gap is formed between the end portion on the middle position P11 side of the score line K24 and the middle position P11 of the score line K24). That is, the ruled line (may be a broken line C21) is a midway position (seventh midway position) P3 ′ and a midway position (eighth midway position) P11 from the back side end of the score line K20 to the front side end. It is only necessary to be formed in a direction between the intermediate position P3 ′ and the intermediate position P11.

  Further, the broken line (third broken line) C31 is an intermediate position P12 of the cut line K34 (that is, the intermediate position from the rear end to the front end of the cut line K34 (the intermediate position P12 is the cut line K30). It can also be said to be an intermediate position from the back side end part to the front side end part)) from the back side to the back side, and is formed in a straight line obliquely upward with respect to the horizontal direction (the direction of the lower side and the upper side of the right side part 30), The upper end of the polygonal line C31 is located at an intermediate position (fifth intermediate position) P4 ''. This midway position P4 '' is a midway position from the notch KV on the back side of the right side 30 to the top of the side (a midpoint from the top to the bottom of the back side of the upper right side 35). (That is, the midway position P4 '' is on the side on the back side of the upper right side surface part 35, above the notch KV, and below the upper end of the side part on the back side of the upper right side part 35. In the assembled packaging box A1, the midway position P4 ″ overlaps (may match) the midway positions P4, P4 ′ (that is, the midway position P4 ″ is the midway positions P4, P4 ′. Is the corresponding position). The midway position P <b> 4 ″ may be a midway position from the upper end of the back side of the right side 30 to the notch KV in the back side of the right side 30. That is, the broken line C31 is formed from the midway position P4 '' toward the midway position of the score line K24. The broken line C31 is formed symmetrically with the broken line C21 (in the assembled state of the packaging box A1, it is formed symmetrically with respect to the left side 20 and the right side 30 via the center plane parallel to the left side 20 and the right side 30). In the state, it is formed symmetrically on the left and right lines via the center line in the vertical direction). The inclination angle of the broken line C31 with respect to the horizontal direction (for example, the direction of the lower side of the right side surface portion 30) and the inclination angle of the broken line C45 with respect to the horizontal direction (for example, the direction of the lower side of the back surface portion 40) are the same (may be substantially the same). In the unfolded state of the sleeve-like portion 5, the fold line C31 and the fold line C45 have a single straight line shape (that is, they are formed on the same straight line). Thereby, by setting one of the polygonal line C31 and the polygonal line C45 to approximately 45 degrees with respect to the horizontal direction, the other can be easily set to approximately 45 degrees with respect to the horizontal direction.

  One end of the ruled line formed along the broken line C31 is located at a midway position P4 '', and the other end of the ruled line is located at a midway position P12 (sixth midway position) of the cut line K34. However, the ruled line does not have to be formed up to the midway position P4 ″ or the midway position P12 of the cut line K34, and the end of the ruled line may be formed to the midway position toward the midway position P4 ″. (In other words, a gap is formed between the end of the ruled line halfway position P4 ″ and the halfway position P4 ″), and the end of the ruled line goes to the halfway position P12 of the cut line K34. It may be formed up to an intermediate position (that is, an interval is formed between the end portion of the ruled line K34 on the intermediate position P12 side and the intermediate position P12 of the score line K34). That is, the ruled line (which may be the broken line C31) is located at a midway position (fifth midway position) P4 ″ (P4 ′) and a halfway position (first halfway) from the back side end to the front side end of the score line K30. 6 halfway position) It suffices if it is formed at a position between P12 and a direction connecting halfway position P4 ″ and halfway position P12.

  A broken line C31 'composed of the broken line C31 and the broken line C49 may be used as the third broken line. That is, the broken line C31 may be the third broken line, or the broken line C31 'may be the third broken line.

  Further, the broken line C49 is formed in a straight line inclined from the middle position (fifth middle position) P4 ′ with respect to the broken line C48 between the adhesive margin portion 49 and the back surface portion 40, and the horizontal direction of the broken line C49 (the broken line C48 and The angle with respect to the direction perpendicular to the horizontal direction is formed to be the same as the angle with respect to the horizontal direction of the broken line C45, and the folded line C45 and the broken line C49 have a single straight line shape (that is, the same straight line). Formed into a shape). This intermediate position P4 ′ is from the position P8 of the cut line K5 in the side on the back side of the adhesive margin 49 (the lower end of the side on the back side of the upper margin 49-2) to the upper end of the side on the back side. It is a midway position (upper end of the side part on the back side of the upper adhesive margin 49-2), and the midway position P4 ′ overlaps with the midway position P4 (may be coincident). In other words, the midway position P4 and the midway position P4 ′ are in the same position in the vertical direction, the midway position P4 is a position on the right side of the back surface 40, and the midway position P4 ′ is the glue margin 49. The two sides are in contact with each other via a polygonal line C48 (that is, the two sides and the polygonal line C48 overlap (may be coincident), so that the intermediate position P4 In the state where the packaging box A1 is assembled, the broken line C49 is overlapped with the broken line C31 along the broken line C31. The ruled line may not be formed up to the midway position P4 ′, and an interval may be formed between the ruled line and the midway position P4 ′.

  The angle of the polygonal lines C42, C43, C44, C45 and the polygonal lines C21, C31, C49 with respect to the horizontal direction (the direction of the lower side and the upper side of the front part 10, the left side part 20, and the right side part 30) is approximately 45 degrees (specifically, Is 40 to 50 degrees, preferably 45 degrees). The angle of the broken lines C42, C43, C44, C45 and the broken lines C21, C31, C49 with respect to the horizontal direction is approximately 45 degrees (specifically, 40 to 50 degrees, preferably 45 degrees). The length at which the lower end is pulled outward can be lengthened, the inclination angle of the lower side of the lower left region 47L and the lower side of the lower right region 47R with respect to the left-right direction can be increased, and the cut lines K42 and K43 can be easily broken. Since the inclination angle of the lower side of the region 47L and the lower side of the lower right region 47R with respect to the left and right direction can be increased, the inclination angle of the lower side of the back side regions 27 and 37 and the lower region 49-2a with respect to the front and rear direction can be increased. The cut lines K24-1, K34-1, and K49 can be easily broken.

  Further, as described above, each of the cut lines and the broken lines in the cut line K5 are formed, so that the respective parts constituting the packaging box A1 are partitioned as follows.

  That is, the lower part of the front part 10 than the cut line K10 is the lower front part 12, and the upper part of the cut line K10 is the upper front part 15.

It becomes. That is, the upper right side surface portion 35 is partitioned into a front side region 36 and a back side region 37 via a polygonal line C31.

  Further, the lower portion of the back surface portion 40 than the cut line K40 becomes the lower back surface portion 42, and the upper portion of the back surface portion 40 above the cut line K40 becomes the upper back surface portion 45. Further, the area surrounded by the cut lines K41, K44, and K45 and the broken line C41 in the lower back surface portion 42 becomes the push portion 44, and the region other than the push portion 44 in the lower back surface portion 42 becomes the lower back surface portion main body 43. In the upper back surface portion 45, a region surrounded by the polygonal lines C42, C43, C44, and C45 is a central region 46, and a region on the left side of the central region 46 from the polygonal line C46 is a central left region 46L.

The region on the opposite side of the center region 46 via the upper left region 48L becomes the upper left region 48L, and is located above the polygonal line C45 and on the right side (center via the polygonal line C45 Region on the opposite side) is the upper right region 48R and pass 46. In other words, the upper back surface portion 45 is connected to the central region 46, the lower left region 47L, the lower right region 47R, the upper left region 48L, and the upper right region 48R via the broken line C42, C43, C44, C45. It is partitioned. The central region 46, the lower left region 47L, and the lower right region 47R constitute the upper back surface body 45-1.

Strictly speaking, the central region 46 can be said to be “a region between the polygonal line C42 or the polygonal line C42 and its extension line and the polygonal line C43 or the polygonal line C43 and its extension line”. It can be said that the region is between C42 and the broken line C43.

  A portion below the cut line K49 in the adhesive margin 49 becomes a lower adhesive margin 49-1, and a portion above the cut line K49 in the adhesive margin 49 becomes an upper adhesive margin 49-2. In the upper glue margin 49-2, the lower side of the broken line C49 is the lower region 49-2a, and the upper side of the broken line C49 is the upper region 49-2b. In the case where the right surface portion is configured by the right side surface portion 30 and the glue margin portion 49, the upper glue margin portion 49-2 and the upper right side surface portion 35 constitute an upper right surface portion 35 '.

The length from the base end (side on the left side 20) to the tip (side opposite to the left side 20) of the flap 120 is the lateral length of the front 10 and back 40 ( For example, when the upper surface of the packaging box A1 is in a closed state, the length between the broken line C20 and the broken line C30 is less than half of the broken line C20 and the broken line C30). A gap is formed. A folding ruled line is formed along the broken line C120 by pressing from the inside (that is, the folded line C120 is formed by a folded ruled line).

Note that a crease line is formed along the crease line C140 by pressing from the inside (that is, the crease line C140 is formed by a crease line).

  As described above, the lid portions 110 and 140 and the flap portions 120 and 130 open and close the upper surface of the packaging box A1, and in particular, the upper surface of the packaging box A1 by closing the lid portions 110 and 140. Is blocked. In addition, the cover parts 110 and 140 and the flap parts 120 and 130 are in an upright state in advance, and the upper part of the packaging box A1 is open. In addition, although the cover parts 110 and 140 are provided continuously from the upper side of the front part 10 and the upper part of the back part 40, the cover part for closing the upper surface of the packaging box A1 is in each part which comprises the sleeve-like part 5. What is necessary is just to be connected from at least one upper side.

  A method of using the packaging box A1 having the above configuration will be described. In the state where the packaging box A1 is assembled, the state shown in FIGS. 1 to 5 is obtained, the bottom surface portion 50 is substantially flat, and each member constituting the sleeve-shaped portion 5 (the front surface portion 10, the left side surface portion 20, the right side surface portion 30, Adjacent members in the back 40) are at right angles to each other. Further, the front surface portion 10 and the back surface portion 40 are parallel to each other, and the left side surface portion 20 and the right side surface portion 30 are parallel to each other.

  And the to-be-contained item (product) G (refer FIG. 13) is accommodated from the upper direction of packaging box A1. The lid portions 110 and 140 and the flap portions 120 and 130 are erected upward in advance with respect to the sleeve-like portion 5, and the upper portion of the packaging box A1 is open. What is necessary is just to store the thing G from the upper direction of packaging box A1 as it is. 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. 10 is obtained. That is, in the state shown in FIG. 10, the lid portions 110 and 140 are fixed in a closed state.

  When the objects to be stored are packaged in the packaging box A1 with the lids 110 and 140 closed as described above, the packaging box A1 storing the objects to be stored G is transported to a place where the objects to be stored A1 are displayed.

  Next, in order to set the storage items in a displayed state, the upper component A-2 of the packaging box A1 is removed as described below.

  That is, the pushing part 44 in the back surface part 40 is pushed, and the pushing part 44 is rotated inside via the broken line C41. That is, by pushing the pushing portion 44 inward, the cut line K41 is broken, and the pushing portion 44 is rotated via the broken line C41. Then, since a space for inserting a finger is formed below the central region 46, a finger of one hand is inserted below the central region 46, and the lower end of the central region 46 (“upper back surface main body 45-1. (It may be the lower end of the upper back surface portion 45) or “the central portion in the left-right direction at the lower end of the upper back surface main body 45-1 (may be the upper back surface portion 45)”. To catch.

  Thereafter, by pulling the lower end of the central region 46 outward, the lower left region 47L and the lower right region 47R 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 lower left region 47L rotates inward (may be bent) with respect to the central region 46 via the broken line C42, and the lower right region 47R moves inward with respect to the central region 46 via the broken line C43. Rotate (may be bent). Further, the central region 46 rotates (may be bent) with respect to the upper left region 48L and the upper right region 48R not only through the upper side of the back surface portion 40 but also through the broken lines C44 and C45 (that is, the upper and lower surfaces). The main body 45-1 (which may be the central region 46) rotates with respect to the upper left region 48L via the polygonal line C44 and also rotates with respect to the upper right region 48R and bulges outward. The broken lines C44 and C45 are valley-folded when viewed from the outside of the packaging box A1. Moreover, since the broken line C46 is provided, the center area | region 46 will be in the state bent via the broken line C46. At that time, the broken line C46 is a mountain fold as viewed from the outside.

  In particular, since the polygonal lines C42 and C43 are provided, the side portion along the cut line K42 in the lower left region 47L (the lower side of the lower left region 47L) and the side portion along the cut line K43 in the lower right region 47R (lower side) The lower side of the right region 47R is easily inclined in the front-rear direction, and the break lines K42 and K43 are easily broken.

  Further, since the broken lines C44 and C45 are provided and the broken line C46 is provided, the lower end of the central region 46 can be easily pulled outward, and the score lines K42 and K43 are easily broken. That is, since the upper ends of the polygonal lines C42 and C43 are at intermediate positions P3 and P4, if the polygonal lines C44 and C45 are not provided, the upper back surface portion 45 is difficult to bulge outward, but the polygonal lines C44 and C45 are provided. The upper back surface main body 45-1 is likely to bulge outward. Further, since the central region 46 can be folded in two by the broken line C46, the central region 46 can be easily pulled outward.

  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 side region 37 is broken from the back side (see FIG. 11).

  That is, by pulling the lower end of the central region 46 outward, the back side region 27 rotates inward (may be bent) with respect to the front side region 26 via the broken line C21 (that is, the upper left side surface portion). 25 is bent via the broken line C21), the back side region 27 tends to be separated laterally with respect to the lower left side surface portion 22, and the lower region 49-2a of the upper adhesive margin 49-2 is the upper region 49-. 2b is turned inward via a polygonal line C49 (or may be bent) (that is, the upper glue margin 49-2 is bent via a polygonal line C49), and the upper region 49-2b is lower glue margin The part on the back side of the cut line K24-1 and the cut line K49 are broken in an attempt to be separated from the portion 49-1. In addition, since the margin part 49 is adhere | attached on the right side surface part 30, when the lower side area | region 49-2a rotates with respect to the upper side area | region 49-2b, the back side area | region 37 is with respect to the front side area | region 36. It is turned inward (may be bent) via the polygonal line C31 (that is, the upper right side surface portion 35 is bent via the polygonal line C31). In addition, since the notch part KV is provided in the right side surface part 30, when the cut line K49 is broken, the cut line K34-1 is not broken.

  Thereafter, by further pulling the lower end of the center region 46 outward, the back side region 37 tries to be separated laterally with respect to the lower right side surface part 32, and the cut line K34-1 is broken and the back side region 27 is A part on the front side of the cut line K24-1 (the remaining part that is not broken) breaks in an attempt to be separated from the lower left side part 22 in the lateral direction.

  In addition, the back side area | region 27 rotates inside via the broken line C21 with respect to the front side area | region 26, and the lower area 49-2a rotates inside via the broken line C49 with respect to the upper area 49-2b. Since the back side area 37 rotates inward with respect to the front side area 36 via the polygonal line C31, the polygonal line C21, the polygonal line C49, and the polygonal line C31 are in a mountain fold state as viewed from the outside.

  Particularly, since the polygonal lines C21, C31, C49 are provided, the back side regions 27, 37 are easy to rotate via the polygonal lines C21, C31, and the lower region 49-2a is arranged via the polygonal line C49. It is easy to rotate, and the cut lines K24-1, K34-1 and K49 can be easily broken.

  Note that the cut lines K42 and K43 and the cut lines K24-1, K34-1, and K49 are broken by pulling the lower end of the central region 46 outward, so in practice, the lower end of the central region 46 is pulled outward. By one operation, from the cut lines K42 and K43 to the cut lines K24-1 and K34-1 (that is, for the cut line K34-1 through the cut line K49, the cut line K34-1) (cut line K24-1, (To the end of the front side of K34-1) can be broken. That is, a region between the pair of cut lines K44 and K45 in the lower back surface portion 42 is pushed from the outside, a finger is caught on the lower end of the upper back surface main body 45-1, and the lower end of the upper back surface main body 45-1 is pulled outward. As a result, the upper back surface main body 45-1 bends through the broken lines C42, C43, C46, and also bends through the broken lines C44, C45, and the upper back surface main body 45-1 bulges outward. The cut line K40 is broken, and the back side region 37, which is the back side region of the upper right side surface portion 35 with respect to the broken line C31, rotates inwardly via the broken line C31, and the back side region 37 and the right side surface portion on the cut line K30. The cut line between the lower right side surface portions 32, which is a region below the 30 cut line K30, is broken, and the back side region 27, which is a region on the back side from the broken line C21 in the upper left side surface portion 25, is broken. Score line between the lower left side surface 22 than the score line K20 rear side region 27 and the left side surface 20 is a lower region of the score line K20 rotated inwardly through the C21 is broken.

  When the cut lines K24-1, K49, and K34-1 are broken, the lower end of the central region 46 is further pulled outward, and the central region 46 is pulled upward, so that the lower left side 22 and the rear surface The side region 27 tends to be separated in the vertical direction, and the lower region 49-2a, the upper region 49-2b, the lower right side surface portion 32, and the back side region 37 are about to be separated in the vertical direction. −1, K49, and K34-1 break. That is, since not only the horizontal separation operation but also the vertical separation operation can be obtained, the score lines K24-1, K49, and K34-1 can be easily broken.

  In particular, since the upper ends of the polygonal lines C21, C31, and C49 are set to the positions of intermediate positions P3 ′, P4 ′, and P4 ″, the lengths of the polygonal lines C21 and C31 are also between the intermediate position P11 and the upper corner of the left side surface portion 20. Compared to the case where a broken line is provided between the intermediate position P12 and the upper corner portion of the right side surface portion 30 (that is, in the case of a configuration similar to the conventional example shown in FIG. 38), the lower end of the central region 46 is reduced. Since the broken lines C21 and C31 are easily bent by pulling, the break lines K24-1 and K34-1 can be easily broken.

  Further, since the upper ends of the broken lines C42 and C43 are set at intermediate positions P3 and P4, even if the length between the upper side of the back surface portion 40 and the score line K41 is increased, the length of the broken lines C42 and C43 is the contact P1. Since it can be shortened compared with the case where a broken line is provided between the upper corner portion of P2 and the back surface portion 40 (that is, in the case of the configuration similar to the conventional example shown in FIG. The broken lines C42 and C43 are bent.

  That is, instead of the polygonal lines C42 and C43, a polygonal line between the contact points P1 and P2 and the upper corner of the back surface portion 40 is used. Instead of the polygonal lines C21 and C31, a polygonal line between the intermediate position P11 and the upper corner of the left side surface portion 20 Assuming that it is a fold line between the position P12 and the upper corner portion of the right side surface portion 30, these fold lines are less likely to be bent due to the length between the upper side of the back surface portion 40 and the cut line K41, and the cut lines K24-1, K34. However, in the present embodiment, such a problem can be solved.

  Further, the broken line C42, the broken line C44, and the broken line C21 are in contact with each other at the midway position P3 (when the broken line is spaced from the midway position P3, the extended line of the broken line is in contact with the midway position P3). When the upper back surface main body 45-1 bulges outward, the back side region 27 smoothly rotates with respect to the front side region 26, and the break line K24-1 is easily broken. Similarly, the broken line C43, the broken line C45, and the broken line C31 (and the broken line C49) are in contact with each other at the midway position P4 (P4 ′, P4 ″) (the broken line is in the midway position P4 (P4 ′, P4 ″)). If there is a gap between the two, the extension line of the broken line is in contact with the intermediate position P4 (P4 ′, P4 ″)), so that the upper back surface main body 45-1 bulges outward and smoothly. The back side region 37 rotates with respect to the front side region 36, and the break line K34-1 is easily broken.

  After that, as shown in FIG. 12, the score lines K24 and K34 are broken toward the front side by pulling up the hand having the central region 46 upward. That is, the cut line K24-2 which is a portion between the lower left side surface portion 22 and the front side region 26 in the cut line K24, and the cut line K34-2 which is a portion between the lower right side surface portion 32 and the front side region 36 in the cut line K34. And to the end position on the front side. In that case, as shown in FIG. 12, it is preferable to make the other hand hold the back side portion of the lower component A-1. That is, when pressing with the left hand, as shown in FIG. 12, when pressing the upper ends of the corners of the lower back surface portion 42 and the lower right side surface portion 32 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 left side surface portion 22 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.

  In other words, the cut line K34 will be described as an example. If the direction of the force F applied to the fracture location 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 fracture location is The angle α formed by the direction of the force F applied to the fracture location and the fracture direction is an acute angle (as shown in FIG. 15A), and the force F applied to the fracture location is The component F1 in the direction perpendicular to the breaking direction and the component F2 in the breaking direction are divided into components F2 and not only the component F1, but also the breakage is facilitated. Compared with this case, when the direction of the score line is the horizontal direction, as shown in FIG. 15B, 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 in 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 is 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 case of the cut line K24 is the same as that of the cut line K34.

  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 portion 40 and the broken lines C44 and C45, so the lower end of the central region 46 is pulled upward in the vertical direction. As the lower end of the central region 46 is pulled upward, the lower ends of the lower left region 47L and the lower right region 47R are also pulled upward, but the direction of the force applied to the breakage point is more than the direction perpendicular to the breakage direction of the score line. Since it is inclined in the direction of break (the direction along the cut line and toward the break side) (the angle between the direction of the force applied to the break and the break direction is an acute angle), the cut line is broken more Can be easier.

  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 K16 and K17 are broken by pulling the upper component A-2 further to the front side (or the lower front side). The cut lines K14 and K15 are broken, the cut line K11 is finally broken, and 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. 13 and 14, and the object G is stored in the lower component A-1, so in this state the object to be stored Display object G.

  In addition, since the lower front part 12 is formed in the substantially U shape and the part except left and right both 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 packaging box A1, 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 A1 of the present embodiment, even if the length between the upper side of the back surface portion 40 and the cut line K41 is increased, the lengths of the broken lines C21 and C31 can be shortened, Since the fold lines C21 and C31 are easily bent by pulling the lower end, the break lines K24-1 and K34-1 can be easily broken.

That is, the broken line C31 is in the horizontal direction (the lower side of the right side surface 30) from the midway position P12 of the cut line K34 (that is, the midway position from the back side end to the front side end of the cut line K34). The upper end of the polygonal line C31 is located at a midway position P4 ″. This midway position P4 '' is a midway position from the contact point P13 with the cut line K34 on the back side of the right side surface 30 to the upper end of the back side, and in the assembled packaging box A2, The position P4 ″ overlaps with the intermediate positions P4 and P4 ′ (that is, the intermediate position P4 ″ is a position corresponding to the intermediate positions P4 and P4 ′). The midway position P4 ″ may be a midway position from the contact point P13 with the cut line K34 on the back side of the right side 30 to the upper end of the back side. That is, the broken line C31 is formed from the midway position P4 '' toward the midway position of the score line K24. The polygonal line C31 is formed symmetrically with the polygonal line C21.

  One end of the ruled line formed along the broken line C31 is located at a midway position P4 '', and the other end of the ruled line is located at a midway position P12 (sixth midway position) of the cut line K34.

  The contents not described above in the sleeve-like portion 5 are the same as those in the sleeve-like portion 5 of the first embodiment, and detailed description thereof is omitted.

  Further, the bottom surface portion 50 includes a first piece portion 160, a second piece portion 170, a third piece portion 180, and a fourth piece portion 190, and the configuration of each portion of the bottom surface portion 50 is an example. Same as 1. The lid portions 110 and 140 and the flap portions 120 and 130 have the same configuration as in the first embodiment.

  A method of using the packaging box A2 having the above configuration will be described. In a state where the packaging box A2 is assembled, the state shown in FIGS. 16 to 19 is obtained, the bottom surface portion 50 is substantially flat, and each member constituting the sleeve-shaped portion 5 (the front surface portion 10, the left side surface portion 20, the right side surface portion 30, Adjacent members in the back 40) are at right angles to each other. Further, the front surface portion 10 and the back surface portion 40 are parallel to each other, and the left side surface portion 20 and the right side surface portion 30 are parallel to each other.

  And a to-be-contained item (product) is accommodated from the upper direction of packaging box A2. The lid portions 110 and 140 and the flap portions 120 and 130 are erected upward in advance with respect to the sleeve-like portion 5 and the upper portion of the packaging box A2 is open. What is necessary is just to store an object from the upper direction of packaging box A2. 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. 24 is obtained. That is, in the state shown in FIG. 24, the lid portions 110 and 140 are fixed in the closed state.

  When the objects to be stored are packaged in the packaging box A2 with the lid portions 110 and 140 closed as described above, the packaging box A2 storing the objects to be stored is transported to a place where the objects to be stored A2 are displayed.

  Next, in order to set the storage items in a displayed state, the upper component A-2 of the packaging box A2 is removed as described below.

  That is, the pushing part 44 in the back surface part 40 is pushed, and the pushing part 44 is rotated inside via the broken line C41. That is, by pushing the pushing portion 44 inward, the cut line K41 is broken, and the pushing portion 44 is rotated via 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 lower end of the central region 46 (“at the lower end of the upper back surface portion 45). Hang your finger on the “right and left center”.

  Thereafter, by pulling the lower end of the central region 46 outward, the lower left region 47L and the lower right region 47R 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 C47 and C48 are in a mountain fold state as viewed from the outside. That is, the lower left region 47L rotates inward (may be bent) with respect to the central region 46 via the broken line C47, and the lower right region 47R moves inward with respect to the central region 46 via the broken line C48. Rotate (may be bent). Further, the upper back surface main body 45-1 rotates (may be bent) not only through the upper side of the back surface portion 40 but also through the fold lines C44 and C45 (that is, the upper back surface main body 45-1 is directed outward). The bent lines C44 and C45 are valley-folded when viewed from the outside of the packaging box A2.

  In particular, since the broken lines C47 and C48 are provided, the side portion along the cut line K42 in the lower left region 47L (the lower side of the lower left region 47L) and the side portion along the cut line K43 in the lower right region 47R (lower side) The lower side of the right region 47R is easily inclined in the front-rear direction, and the break lines K42 and K43 are easily broken.

  Further, since the broken lines C44 and C45 are provided, the lower end of the central region 46 can be easily pulled outward, and the cut lines K42 and K43 are easily broken. In other words, the upper back surface 45 is provided only with the broken lines C47 and C48 in addition to the broken lines C44 and C45. Therefore, if the broken lines C44 and C45 are not provided, the upper back surface 45 is unlikely to bulge outward. However, since the broken lines C44 and C45 are provided, the upper back body 45-1 is likely to bulge outward.

  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. A cut line K34-1 between the lower right side surface portion 32 and the back side region 37 is broken from the back side (see FIG. 25).

  In other words, by pulling the lower end of the central region 46 outward, the back side region 27 rotates inward (may be bent) with respect to the front side region 26 via the broken line C21, so that the back side region 27 The lower region 49-2a of the upper glue margin 49-2 is rotated inward (folded) via the broken line C49 with respect to the lower left side portion 22 in the lateral direction. The lower region 49-2a may be spaced apart from the lower adhesive margin 49-1, and the portion on the back side of the cut line K24-1 breaks, and the cut line K49. And the part by the side of the back of cut line K34-1 breaks. In addition, since the margin part 49 is adhere | attached on the right side surface part 30, when the lower side area | region 49-2a rotates with respect to the upper side area | region 49-2b, the back side area | region 37 is with respect to the front side area | region 36. It is rotated inward (may be bent) via the broken line C31.

  Thereafter, by further pulling the lower end of the central region 46 outward, the rear side region 37 tries to be separated laterally with respect to the lower right side surface portion 32, and the front side portion of the score line K34-1 (not broken). (The remaining portion) is broken, and the rear side region 27 is about to be separated laterally with respect to the lower left side surface portion 22, and the front side portion (the remaining portion not broken) of the cut line K24-1 is broken. .

  In addition, the back side area | region 27 rotates inside via the broken line C21 with respect to the front side area | region 26, and the lower area 49-2a rotates inside via the broken line C49 with respect to the upper area 49-2b. Since the back side area 37 rotates inward with respect to the front side area 36 via the polygonal line C31, the polygonal line C21, the polygonal line C49, and the polygonal line C31 are in a mountain fold state as viewed from the outside.

  In particular, since the polygonal lines C21, C31, and C49 are provided, the back side regions 27 and 37 can be easily rotated through the polygonal lines C21 and C31, and the lower region 49-2a can be rotated through the polygonal line C49. This makes it easier to break the cut lines K24-1, K34-1 and K49.

  Note that the cut lines K42 and K43 and the cut lines K24-1, K34-1, and K49 are broken by pulling the lower end of the central region 46 outward, so in practice, the lower end of the central region 46 is pulled outward. With one operation, the cut lines K42 and K43 to the cut lines K24-1 and K34-1 (up to the front end portions of the cut lines K24-1 and K34-1) can be broken. That is, a region between the pair of cut lines K44 and K45 in the lower back surface portion 42 is pushed from the outside, a finger is caught on the lower end of the upper back surface main body 45-1, and the lower end of the upper back surface main body 45-1 is pulled outward. As a result, the upper back surface main body 45-1 bends through the polygonal lines C47 and C48 and bends through the polygonal lines C44 and C45, so that the upper back surface main body 45-1 bulges outward and cuts. The line of sight K40 is broken, and the back side region 37, which is the region on the back side of the fold line C31 in the upper right side surface part 35, is rotated inward via the fold line C31, so The cut line between the lower right side surface portion 32 that is a region below the cut line K30 is broken, and the back side region 27 that is a back side region from the broken line C21 in the upper left side surface portion 25 is a broken line C21. Through score line between the lower left side surface 22 than the score line K20 rear side region 27 and the left side surface 20 is a lower region of the score line K20 pivots inwardly to fracture.

  When the cut lines K24-1, K49, and K34-1 are broken, the lower end of the central region 46 is further pulled outward, and the central region 46 is pulled upward, so that the lower left side 22 and the rear surface The side region 27 tends to be separated in the vertical direction, and the lower region 49-2a, the upper region 49-2b, the lower right side surface portion 32, and the back side region 37 are about to be separated in the vertical direction. −1, K49, and K34-1 break. That is, since not only the horizontal separation operation but also the vertical separation operation can be obtained, the score lines K24-1, K49, and K34-1 can be easily broken.

  In particular, since the upper ends of the polygonal lines C21, C31, and C49 are set to the positions of intermediate positions P3 ′, P4 ′, and P4 ″, the lengths of the polygonal lines C21 and C31 are also between the intermediate position P11 and the upper corner of the left side surface portion 20. Compared to the case where a broken line is provided between the intermediate position P12 and the upper corner portion of the right side surface portion 30 (that is, in the case of a configuration similar to the conventional example shown in FIG. 38), the lower end of the central region 46 is reduced. By pulling, the broken lines C21 and C31 are easily bent, and the break lines K24-1 and K34-1 can be easily broken.

  That is, instead of the polygonal lines C21 and C31, if the polygonal line between the middle position P11 and the upper corner of the left side 20 is a polygonal line between the middle position P12 and the upper corner of the right side 30, the polygonal line is the back side 40. As the length between the upper side and the cut line K41 becomes longer, it becomes difficult to bend and the cut lines K24-1 and K34-1 are difficult to break, but in this embodiment, such a problem is solved. Can do.

  Further, the broken line C44 and the broken line C21 are in contact with each other at the midway position P3 (P3 ′) (when the broken line is spaced from the midway position P3, the extended line of the broken line is at the midway position P3 (P3 ′). Therefore, when the upper back surface main body 45-1 bulges outward, the back surface region 27 smoothly rotates with respect to the front surface region 26, and the break line K24-1 is easily broken. . Similarly, the polygonal line C45 and the polygonal line C31 (and the polygonal line C49) are in contact with each other at the position of the intermediate position P4 (P4 ′, P4 ″) (the polygonal line is between the intermediate positions P4 (P4 ′, P4 ″)). If there is a gap, the extended line of the broken line is in contact with the intermediate position P4 (P4 ′, P4 ″)). 37 rotates with respect to the front side area | region 36, and the fracture | rupture of the cut line K34-1 becomes easy.

  Further, since the upper ends of the broken lines C47 and C48 are not formed up to the upper side of the back surface portion 40, bending via the broken lines C44 and C45 can be promoted, and the score lines K42 and K43 can be easily broken. That is, if the broken lines C47 and C48 are formed up to the upper side of the back surface portion 40, if the lower end of the central region 46 is pulled, the upper back surface main body 45-1 is bent via the broken lines C47 and C48. , When the bending by C45 becomes weak, the upper back surface main body 45-1 is difficult to bulge outward, and the cut lines K42 and K43 are not broken, and the upper ends of the broken lines C47 and C48 are not formed up to the upper side of the back surface part 40 It becomes difficult compared with.

  Thereafter, as shown in FIG. 26, the hands having the central region 46 are pulled upward, whereby the score lines K24 and K34 are broken toward the front side. That is, the cut line K24-2 which is a portion between the lower left side surface portion 22 and the front side region 26 in the cut line K24, and the cut line K34-2 which is a portion between the lower right side surface portion 32 and the front side region 36 in the cut line K34. And to the end position on the front side. In that case, as shown in FIG. 26, it is preferable to make the state which hold | suppressed 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. 26, when the upper ends of the corners of the lower back surface portion 42 and the lower right side surface portion 32 are pressed and pressed 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 left side surface portion 22 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.

  As in the case of the first embodiment, when the cut lines K24 and K34 are broken to the front side, they are inclined with respect to the horizontal direction so that the cut lines K24 and K34 become upward as they go to the front side. Therefore, the cut lines K24 and 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.

  Further, as in the case of the first embodiment, the arrangement direction of the plurality of cuts 210 on the cut line K42 is upward as it goes from the cut line K41 side to 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 slanted so as to be on the upper side from the cut line K41 side toward the right side end portion of the back surface part 40. Since it is inclined upward, it can be said that it is easy to break for the same reason as in the case of the cut lines K24 and K34.

  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 K16 and K17 are broken by pulling the upper component A-2 further to the front side (or the lower front side). The cut lines K14 and K15 are broken, the cut line K11 is finally broken, and 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. 13 and 14, and the object G is stored in the lower component A-1, so in this state the object to be stored Display object G.

  In addition, since the lower front part 12 is formed in the substantially U shape and the part except left and right both 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 packaging box A2, 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 A2 of this embodiment, even if the length between the upper side of the back surface portion 40 and the cut line K41 is increased, the lengths of the broken lines C21 and C31 can be shortened, and the lower end of the central region 46 Since the broken lines C21 and C31 are easily bent by pulling, the break lines K24-1 and K34-1 can be easily broken.

  Moreover, since the space which puts a finger in the lower side of the center area | region 46 is formed by pushing the pushing part 44, when removing the upper side structure part A-2 of packaging box A2, the operation | movement which hooks a finger first is easy. Can be done.

  Further, as described above, the broken lines C44, C45, C47, and C48 are provided, so that the cut lines K42 and K43 are easily broken, and the broken lines C21 and C31 are provided, so that the cut line K24-1 is provided. , K34-1 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.

  In the above description, the position P5 and the position P6 are provided with a gap therebetween. However, as in the third embodiment, the position P5 and the position P6 overlap each other, and the broken line C44 and the broken line C45 are formed on the back surface portion. You may make it contact | connect in position P5 'on 40 upper side.

  Further, in this embodiment, as in the first embodiment, the notch portion KV may be provided in the right side surface portion 30.

  Further, although the upper ends of the broken lines C47 and C48 are not formed up to the upper side of the back surface portion 40, the upper ends of the bent lines C47 and C48 may be formed to the upper side of the back surface portion 40. Even in such a configuration, by pulling the lower end of the central region 46, the upper back surface main body 45-1 can bulge outward.

  Next, the packaging box A3 of Example 3 will be described. The packaging box A3 has substantially the same configuration as the packaging box A2 of Example 2, but the configuration of the broken line formed mainly on the back surface portion 40 is different.

  That is, the packaging box A3 is configured as shown in FIGS. 27 to 34, and includes the sleeve-shaped portion 5, the bottom surface portion 50, the lid portions 110 and 140, and the flap portions 120 and 130.

  As in the case of the first and second embodiments, the sleeve-like portion 5 includes a front portion 10, a left side surface portion 20, a right side surface portion 30, a back surface portion 40, and an adhesive margin portion 49. A cut line K5 is formed in the sleeve-like portion 5, and the cut line K5 has the same configuration as the cut line K5 in the first embodiment. The cut line K5 includes cut lines K10, K20, K30, K40, The configuration of the cut lines K10, K20, K30, K40, K49 is the same as the cut lines K10, K20, K30, K40, K49 in the first embodiment.

  Further, in the packaging box A3, the back surface portion 40 is provided with fold lines (may be ruled lines) C41, C44, C45, C46, and the left side surface portion 20 is provided with fold lines (may be ruled lines) C21. 30 is provided with a polygonal line (may be a ruled line) C31, and the glue margin 49 is provided with a polygonal line C49. For the broken lines C41, C44, C45, C46, C21, and C31, they may be bent along these broken lines (that is, “at the positions of these broken lines” or “match the broken lines”). Ruled lines are formed (that is, the broken lines C41, C44, C45, C46, C21, and C31 are formed by folding ruled lines), and the ruled lines are formed by stamped lines pressed from the inside of the blank. . Each ruled line is configured to be visible from the inside and outside of the blank, but may be configured to be hardly visible from the outside of the blank.

  Here, the broken line C41 has the same configuration as the broken line C41 of the first embodiment. The broken line (second broken line) C44 has substantially the same configuration as the broken line C44 of Example 1, and the horizontal direction from the midway position P3 toward the inner side (right side) of the back surface portion 40 with respect to the horizontal direction. The lower end of the broken line C44 is formed at a midway position P3, and the upper end of the broken line C44 is provided at a position P5 ′ on the upper side of the rear part 40. . The position P5 'is a horizontal center position (second center position) on the upper side of the back surface portion 40, and the position P5' exists on an extension line of the broken line C46. In the third embodiment, it can be said that the second midway position and the fourth midway position overlap (may coincide) at the position P5 '.

  The intermediate position P3 is the same as the intermediate position P3 of the first embodiment. The left side HL (the broken line C40) of the side HL (the broken line C40) on the left side of the back surface 40 may also be used. Is the midway position from the upper end of the cut line K5 to the position P7, and the vertical length between the contact point P1 and the midway position P3 (the length between the height position of the midway position P3 and the height position of the contact point P1). ) (Length obtained by subtracting the length between the contact P1 and the lower side of the back surface 40 from the length between the intermediate position P3 and the lower side of the back surface portion 40) L11 and the vertical direction between the upper side of the back surface portion 40 and the intermediate position P3 L12 (which may be a length obtained by subtracting the height of the middle position P3 from the height of the upper side of the back surface portion 40) is substantially the same as L12 (thereby making the directions of the broken lines C44 and C45 with respect to the horizontal direction. However, the intermediate position P3 is ,, length L11 located slightly lower than the middle position P3 of Example 1 is slightly shorter than the length L12.

  The ruled line formed along the broken line C44 is formed from the midway position P3 to the position P5 ′. However, a configuration may be adopted in which a space is provided between the lower end of the ruled line and the midway position P3. And a position between the position P5 ′ and the position P5 ′. That is, the ruled line (which may be a broken line C44) is located at the midway position P4 and the midway position (fourth midway position) from the left side edge of the upper side of the back surface 40 to the right side edge (specifically, the fourth halfway position). May be formed at a position between the positions P5) in a direction connecting the intermediate position P3 and the fourth intermediate position.

  Further, the polygonal line (first polygonal line) C45 is formed symmetrically with the polygonal line C44, and the polygonal line C45 extends in the horizontal direction from the midway position P4 toward the inside (left side) in the lateral direction of the back surface portion 40. The lower end of the polygonal line C45 is in the middle position P4, and the upper end of the polygonal line C45 is provided at a position P5 ′ on the upper side of the rear part 40. . That is, the upper end of the polygonal line C44 and the upper end of the polygonal line C45 are in contact with each other at the position P5 'on the upper side of the back surface portion 40.

  The intermediate position P4 is the right side surface of the side portion HR on the right side surface side of the back surface portion 40 (may be a fold line C48 between the back surface portion 40 and the adhesive margin portion 49), similarly to the intermediate position P4 of the first embodiment. This is a midway position from the upper end of the side HR (which may be the broken line C48) to the position P8 of the score line K5, and the length L21 and the length L22 are substantially the same (thereby, the broken lines C44 and C45). It is easy to make the direction of approximately 45 degrees with respect to the horizontal direction, as is the case with the midway position P3, slightly below the midway position P4 of Example 1, and the length L21 is greater than the length L22. The length L21 is the same as the length L11, and the length L22 is the same as the length L12. Note that the length L11 and the length L12 are the same as the length L12. And the length L21 and the length L22 are the same. It may be.

  The ruled line formed along the broken line C45 is formed from the middle position P4 to the position P5 ′. However, a configuration may be adopted in which a space is provided between the lower end of the ruled line and the middle position P4. And a position between the position P5 ′ and the position P5 ′. That is, the ruled line (which may be a broken line C45) is located at a midway position (second midway position) between the midway position P4 and the end on the right side of the upper side of the back surface 40 to the end on the left side. May be formed in a direction connecting the intermediate position P4 and the second intermediate position at a position between the positions P6).

  A broken line (tenth broken line) C46 is a direction perpendicular to the horizontal direction from the center position P9 in the left-right direction of the score line K41 (the side HL on the left side of the back surface 40 and the side HR on the right side). The lower end of the broken line C46 is at the center position P9, and the upper end of the broken line C46 is in the middle of the position P5 ′. That is, a space is provided between the upper end of the broken line C46 and the position P5 '. The upward extension line of the broken line C46 is in contact with the position P5 '. The ruled line formed along the broken line C46 is formed from the center position P9. However, the ruled line may be configured to have a space between the lower end of the ruled line and the center position P9. Although a space is provided between P5 ′, the upper end of the broken line C46 may be formed up to the position P5 ′. That is, the ruled line (may be a broken line C46) may be formed in a direction connecting the central position P9 and the central position P10 at a position between the central position P9 and the central position P10.

  In the present embodiment, no broken line (ruled line) is provided between the contact P1 and the midway position P3, and no broken line (ruled line) is provided between the contact P2 and the midway position P4.

  A broken line (third broken line) C21 has the same configuration as the broken line C21 of the first embodiment. That is, the broken line C21 is in the horizontal direction (the lower side of the left side 20) from the midway position P11 of the cut line K24 (that is, the midway position from the back side end to the front side end of the cut line K24). The upper end of the polygonal line C21 is located at the midway position P3 ′. As in the case of the first embodiment, the midway position P3 'overlaps with the midway position P3 (may be coincident). 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. The inclination angle of the broken line C21 with respect to the horizontal direction (for example, the direction of the lower side of the left side surface portion 20) and the inclination angle of the broken line C44 with respect to the horizontal direction (for example, the direction of the lower side of the back surface portion 40) are the same. In the state, the polygonal line C21 and the polygonal line C44 have one straight line shape (that is, they are formed on the same straight line). One end of the ruled line formed along the broken line C21 is located at a midway position P3 ′, and the other end of the ruled line is located at a midway position P11 (eighth midway position) of the cut line K24. The ruled line may not be formed up to the midway position P3 ′ or the midway position P11 of the cut line K24, and the end of the ruled line may be formed up to a midway position toward the midway position P3 ′ ( That is, an interval is formed between the end of the ruled line on the middle position P3 ′ side and the middle position P3 ′), and the end of the ruled line is on the way to the middle position P11 of the cut line K24. It may be formed up to a position (that is, a gap is formed between an end portion on the middle position P11 side of the ruled line K24 and a middle position P11 of the score line K24). That is, the ruled line (may be a broken line C21) is a midway position (seventh midway position) P3 ′ and a midway position (eighth midway position) P11 from the back side end of the score line K20 to the front side end. It is only necessary to be formed in a direction between the intermediate position P3 ′ and the intermediate position P11.

  A broken line (fourth broken line) C31 has the same configuration as the broken line C31 of the first embodiment. That is, the broken line C31 is in the horizontal direction (the lower side of the right side surface 30) from the midway position P12 of the cut line K34 (that is, the midway position from the back side end to the front side end of the cut line K34). The upper end of the polygonal line C31 is located at a midway position P4 ″. This midway position P4 '' is a midway position from the contact P13 with the cut line K34 on the back side of the right side 30 to the upper end of the back side, and in the assembled packaging box A3, The position P4 ″ overlaps with the intermediate positions P4 and P4 ′ (may be coincident) (that is, the intermediate position P4 ″ is a position corresponding to the intermediate positions P4 and P ′). That is, the broken line C31 is formed from the midway position P4 '' toward the midway position of the score line K24. The polygonal line C31 is formed symmetrically with the polygonal line C21. One end of the ruled line formed along the broken line C31 is located at a midway position P4 '', and the other end of the ruled line is located at a midway position P12 (sixth midway position) of the cut line K34. However, the ruled line may not be formed up to the midway position P4 ″ or the midway position P12 of the cut line K34, and the ruled line end may be formed up to a midway position toward the midway position P4 ″. Well (that is, an interval is formed between the end of the ruled line halfway position P4 ″ and the halfway position P4 ″), and the end of the ruled line is at the middle position P12 of the cut line K34. It may be formed up to an intermediate position (that is, an interval is formed between the end of the ruled line K34 on the intermediate position P12 side and the intermediate position P12 of the score line K34). That is, the ruled line (which may be the broken line C31) is located at a midway position (fifth midway position) P4 ″ (P4 ′) and a halfway position (first halfway) from the back side end to the front side end of the score line K30. 6 halfway position) It should just be formed in the direction which connects halfway position P3 'and halfway position P12 in the position between P11.

  Further, the midway position P11 of the cut line K24 is located slightly on the back side compared to the case of the first embodiment, and the midway position P12 of the cut line K34 is located slightly on the back side as compared with the case of the first embodiment. Yes.

  Moreover, in Example 1, the notch part KV is provided in the side part by the side of the back of the right side part 30, but in this Example, the notch part is not provided in the part by the side of the back side of the right side part 30. .

  The broken line C49 has the same configuration as the broken line C49 of the first embodiment. That is, the polygonal line C49 is formed in a straight line inclined from the intermediate position P4 with respect to the polygonal line C48 between the glue margin 49 and the back surface part 40, and the angle of the polygonal line C49 with respect to the horizontal direction (the direction perpendicular to the polygonal line C48) is In the state in which the angle of the broken line C45 with respect to the horizontal direction is formed and the packaging box A3 is unfolded, the broken line C45 and the broken line C49 have one straight line shape (that is, they are formed in the same straight line shape). . Similarly to the first embodiment, the midway position P4 ′ is a midway position from the position P7 of the cut line K5 on the back side of the adhesive margin 49 to the upper end of the back side, and the midway position P4. 'Overlaps with the midway position P4 (may match). Moreover, in the state which assembled packaging box A3, the broken line C49 is in the state which corresponded and overlapped with the broken line C31 along the broken line C31. Note that the ruled line along the broken line C49 may not be formed up to the midway position P4, and an interval may be formed between the ruled line and the midway position P4.

  The angle of the broken lines C44, C45 and the broken lines C21, C31, C49 with respect to the horizontal direction is approximately 40 degrees (specifically, 35 to 45 degrees). Thereby, the cut lines K42 and K43 can be easily broken, and the cut lines K24-1, K34-1, and K49 can be easily broken.

  Further, as described above, by forming each of the above-described score lines and each of the above-described broken lines in the score line K5, the front surface portion 10 can be connected to the lower front surface portion via the score line K10 as in the first embodiment. 12 and the upper front surface portion 15, the left side surface portion 20 is partitioned into a lower left side surface portion 22 and an upper left side surface portion 25 via a score line K20, and the upper left side surface portion 25 is separated from the front side region (first 1 front side region) 26 and a back side region (first back side region) 27, and the right side surface portion 30 is partitioned into a lower right side surface portion 32 and an upper right side surface portion 35 via a cut line K30. 35 is partitioned into a front side region (second front side region) 36 and a back side region (second back side region) 37 via a polygonal line C31.

  Similarly to the first embodiment, the back surface portion 40 is partitioned into a lower back surface portion 42 and an upper back surface portion 45 via a cut line K40, and the lower back surface portion 42 is divided into a push portion 44 and a lower back surface portion main body 43. It is partitioned. Further, in the upper back surface portion 45, the region below the fold lines C44, C45 (the region surrounded by the cut line K40, the fold lines C44, C45 and the left and right sides of the back surface portion 40) is the upper back surface body 45-1. The region on the upper side and the left side of the polygonal line C44 (the region on the opposite side of the upper back surface main body 45-1 via the polygonal line C44) is the upper left region 48L, and is the region on the upper side and the right side of the polygonal line C45. (A region on the side opposite to the upper back surface main body 45-1 via the broken line C45) is an upper right region 48R. Further, a region between the broken line C46 and the side portion HL on the left side of the back surface portion 40 is a lower left region 47L, and a region between the broken line C46 and the side portion HR on the right side surface of the back surface portion 40 is a lower right region 47R. .

  As in the first embodiment, the margin portion 49 is divided into a lower margin portion 49-1 and an upper margin portion 49-2 via a cut line K49, and the upper margin portion 49-2 is a broken line. It is divided into a lower region 49-2a and an upper region 49-2b through C49.

  The contents not described above in the sleeve-like portion 5 are the same as those in the sleeve-like portion 5 of the first embodiment, and detailed description thereof is omitted.

  Further, the bottom surface portion 50 includes a first piece portion 160, a second piece portion 170, a third piece portion 180, and a fourth piece portion 190, and the configuration of each portion of the bottom surface portion 50 is an example. Same as 1. The lid portions 110 and 140 and the flap portions 120 and 130 have the same configuration as in the first embodiment.

  A method of using the packaging box A3 having the above configuration will be described. In a state where the packaging box A3 is assembled, the state shown in FIGS. 27 to 30 is obtained, the bottom surface portion 50 is substantially flat, and each member constituting the sleeve-shaped portion 5 (the front surface portion 10, the left side surface portion 20, the right side surface portion 30, Adjacent members in the back 40) are at right angles to each other. Further, the front surface portion 10 and the back surface portion 40 are parallel to each other, and the left side surface portion 20 and the right side surface portion 30 are parallel to each other.

  And a to-be-contained item (product) is accommodated from the upper direction of packaging box A3. The lid portions 110 and 140 and the flap portions 120 and 130 are erected upward in advance with respect to the sleeve-like portion 5, and the upper portion of the packaging box A3 is open. What is necessary is just to store an object from the upper direction of packaging box A3. 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 adhering up to 30, the state shown in FIG. 35 is obtained. That is, in the state shown in FIG. 35, the lid portions 110 and 140 are fixed in a closed state.

  When the objects to be stored are packaged in the packaging box A3 with the lids 110 and 140 closed as described above, the packaging box A3 storing the objects to be stored is transported to a place where the objects to be stored A3 are displayed.

  Next, in order to change the state of the stored items, the upper component A-2 of the packaging box A3 is removed as described below.

  That is, the pushing part 44 in the back surface part 40 is pushed, and the pushing part 44 is rotated inside via the broken line C41. That is, by pushing the pushing portion 44 inward, the cut line K41 is broken, and the pushing portion 44 is rotated via the broken line C41. Then, a space for inserting a finger is formed on the lower side of the upper back surface main body 45-1, so that a finger of one hand is inserted into the lower side of the upper back surface main body 45-1, and the upper back surface body 45- A finger is put on the lower end of 1 (specifically, it may be “the central portion in the left-right direction at the lower end of the upper back surface main body 45-1 (or the upper back surface portion 45)”).

  Thereafter, the lower left region 47L and the lower right region 47R of the upper back surface portion 45 are formed by pulling the lower end of the lower end of the upper back surface portion 45 (strictly speaking, the central portion in the left-right direction at the lower end of the upper back surface portion 45) outward. Gradually pulled from the center in the left-right direction, the cut lines K42 and K43 break. In a state where the lower end of the upper back surface main body 45-1 is pulled outward, the upper back surface main body 45-1 is bent via a broken line C46, and the folded line C46 is in a mountain fold state as viewed from the outside. Further, the upper back surface main body 45-1 rotates (may be bent) via the fold lines C44 and C45 (that is, the upper back surface main body 45-1 bulges outward), The broken lines C44 and C45 are valley-folded when viewed from the outside of the packaging box A3.

  In particular, since the broken line C46 is provided, the side portion along the cut line K42 in the lower left region 47L (the lower side of the lower left region 47L) and the side portion along the cut line K43 in the lower right region 47R (lower right region) The lower side of 47R is easily inclined in the front-rear direction, and the cut lines K42 and K43 are easily broken.

  Moreover, since the broken lines C44 and C45 are provided, the lower end of the upper back surface main body 45-1 can be easily pulled outward, and the score lines K42 and K43 are easily broken. In other words, the upper back surface 45 is provided only with the broken lines C47 and C48 in addition to the broken lines C44 and C45. Therefore, if the broken lines C44 and C45 are not provided, the upper back surface 45 is unlikely to bulge outward. However, since the broken lines C44 and C45 are provided, the upper back body 45-1 is likely to bulge outward.

  Thereafter, by further pulling the lower end of the upper back surface main body 45-1 outward, the cut line K24-1 between the lower left side surface part 22 and the back side region 27 in the cut line K24 is broken from the back side, A cut line K34-1 between the lower right side surface portion 32 and the back side region 37 in the cut line K34 is broken from the back side (see FIG. 36).

  That is, by pulling the lower end of the upper back surface portion 45 outward, the back side region 27 rotates inward (may be bent) with respect to the front side region 26 via the polygonal line C21, and the back side region 27 Tends to be separated from the lower left side surface portion 22 in the lateral direction, and the lower region 49-2a of the upper adhesive margin 49-2 rotates inward with respect to the upper region 49-2b via a broken line C49 ( The lower region 49-2a may be separated laterally from the lower adhesive margin 49-1, and the portion on the back side of the score line K24-1 may break and the score line. The part on the back side of K49 and the cut line K34-1 is broken. In addition, since the margin part 49 is adhere | attached on the right side surface part 30, when the lower side area | region 49-2a rotates with respect to the upper side area | region 49-2b, the back side area | region 37 is with respect to the front side area | region 36. It is rotated inward (may be bent) via the broken line C31.

  Thereafter, by further pulling the lower end of the upper back surface portion 45 outward, the back side region 37 tends to be separated laterally with respect to the lower right side surface portion 32, and the front side portion of the score line K34-1 (broken-off The remaining portion) is broken, and the rear side region 27 is about to be separated laterally with respect to the lower left side surface portion 22, and the front side portion of the cut line K24-1 (the remaining portion that is not broken) is broken. To do.

  In addition, the back side area | region 27 rotates inside via the broken line C21 with respect to the front side area | region 26, and the lower area 49-2a rotates inside via the broken line C49 with respect to the upper area 49-2b. Since the back side area 37 rotates inward with respect to the front side area 36 via the polygonal line C31, the polygonal line C21, the polygonal line C49, and the polygonal line C31 are in a mountain fold state as viewed from the outside.

  In particular, since the polygonal lines C21, C31, and C49 are provided, the back side regions 27 and 37 can be easily rotated through the polygonal lines C21 and C31, and the lower region 49-2a can be rotated through the polygonal line C49. This makes it easier to break the cut lines K24-1, K34-1 and K49.

  Since the cut lines K42 and K43 and the cut lines K24-1, K34-1, and K49 are broken by pulling the lower end of the upper back body 45-1 outward, the upper back body 45- By one operation of pulling the lower end of 1 outward, the cut lines K42 and K43 to the cut lines K24-1 and K34-1 (to the end on the front side of the cut lines K24-1 and K34-1) are broken. be able to. That is, a region between the pair of cut lines K44 and K45 in the lower back surface portion 42 is pushed from the outside, a finger is caught on the lower end of the upper back surface main body 45-1, and the lower end of the upper back surface main body 45-1 is pulled outward. As a result, the upper back surface main body 45-1 bends through the broken line C46 and also bends through the broken lines C44 and C45, so that the upper back surface main body 45-1 bulges outward, and the cut line K40. Is broken and the back side region 37, which is the back side region of the upper right side surface portion 35 with respect to the broken line C31, rotates inwardly via the broken line C31, and the back side region 37 and the cut line of the right side surface portion 30 in the cut line K30. The cut line between the lower right side surface part 32 which is an area below K30 is broken, and the back side area 27 which is an area on the back side with respect to the broken line C21 in the upper left side face part 25 via the broken line C21. Score line between the lower left side surface 22 than the score line K20 rear side region 27 and the left side surface 20 is a lower region of the score line K20 rotated to the side is broken.

  When the cut lines K24-1, K49, K34-1 are broken, the lower left side 22 is pulled by further pulling the lower end of the upper back 45 and pulling the upper back 45 upward. And the rear region 27 are separated from each other in the vertical direction, and the lower region 49-2a and the upper region 49-2b and the lower right side surface portion 32 and the rear region 37 are separated from each other in the vertical direction. The line of sight K24-1, K49, K34-1 breaks. That is, since not only the horizontal separation operation but also the vertical separation operation can be obtained, the score lines K24-1, K49, and K34-1 can be easily broken.

  In particular, since the upper ends of the polygonal lines C21, C31, and C49 are set to the positions of intermediate positions P3 ′, P4 ′, and P4 ″, the lengths of the polygonal lines C21 and C31 are also between the intermediate position P11 and the upper corner of the left side surface portion 20. Compared with the case where a broken line is provided between the intermediate position P12 and the upper corner portion of the right side surface portion 30 (that is, the configuration similar to the conventional example shown in FIG. 38), the upper back surface main body 45- By pulling the lower end of 1, the fold lines C21 and C31 can be easily bent, and the break lines K24-1 and K34-1 can be easily broken.

  That is, instead of the polygonal lines C21 and C31, if the polygonal line between the middle position P11 and the upper corner of the left side 20 is a polygonal line between the middle position P12 and the upper corner of the right side 30, the polygonal line is the back side 40. As the length between the upper side and the cut line K41 becomes longer, it becomes difficult to bend and the cut lines K24-1 and K34-1 are difficult to break, but in this embodiment, such a problem is solved. Can do.

  Thereafter, as shown in FIG. 37, by pulling up the hand having the upper back surface portion 45, the score lines K24 and K34 are broken toward the front side. That is, the cut line K24-2 which is a portion between the lower left side surface portion 22 and the front side region 26 in the cut line K24, and the cut line K34-2 which is a portion between the lower right side surface portion 32 and the front side region 36 in the cut line K34. And to the end position on the front side. In that case, as shown in FIG. 37, 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. 37, the upper ends of the corners of the lower back surface portion 42 and the lower right side surface portion 32 are pressed and pressed with the right hand (in this case, the upper back surface main body 45-1 is held. In order to pull it up with the left hand, the upper ends of the corners of the lower back surface portion 42 and the lower left side surface portion 22 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.

  As in the case of the first embodiment, when the cut lines K24 and K34 are broken to the front side, they are inclined with respect to the horizontal direction so that the cut lines K24 and K34 become upward as they go to the front side. Therefore, the cut lines K24 and 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.

  Further, as in the case of the first embodiment, the arrangement direction of the plurality of cuts 210 on the cut line K42 is upward as it goes from the cut line K41 side to 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 slanted so as to be on the upper side from the cut line K41 side toward the right side end portion of the back surface part 40. Since it is inclined upward, it can be said that it is easy to break for the same reason as in the case of the cut lines K24 and K34.

  After breaking up to the front end position of the score lines K24 and K34, the upper constituent part A-2 is pulled up to the front side obliquely upward so that the upper component A-2 is located at the front end position of the score lines K22 and K32. Since the cut lines K22, K32 are broken while rotating around the center, the cut lines K16, K17 are broken by further pulling the upper component A-2 to the front side (or the lower front side), Thereafter, the score lines K14 and K15 are broken, and finally the score line K11 is broken, so that 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. 13 and 14, and the object G is stored in the lower component A-1, so in this state the object to be stored Display object G.

  In addition, since the lower front part 12 is formed in the substantially U shape and the part except left and right both 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 packaging box A3, 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 A3 of the present embodiment, even if the length between the upper side of the back surface portion 40 and the cut line K41 is increased, the lengths of the broken lines C21 and C31 can be shortened. Since the fold lines C21 and C31 are easily bent by pulling the lower end of -1, the break lines K24-1 and K34-1 can be easily broken.

  Moreover, since the space which puts a finger into the lower side of the upper back part main body 45-1 is formed by pushing the pushing part 44, when removing the upper side structure part A-2 of packaging box A3, a finger | toe is first used. The hooking operation can be easily performed.

  Moreover, since the broken lines C44, C45, and C46 are provided as described above, the cut lines K42 and K43 are easily broken, and the broken lines C21 and C31 are provided, so that the cut lines K24-1 and K34 are provided. −1 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 upper back body 45-1 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.

  In the packaging box A3 of Example 3, the upper end of the broken line C44 and the upper end of the broken line C45 are in contact with each other at the position P5 ′, but the broken line C44 is in contact with the upper side of the back surface portion 40 and the broken line C45 is the back surface portion 40. You may provide a space | interval between the position which touches the upper side of. That is, the upper end of the broken line C44 may be at the position P5 and the upper end of the broken line C45 may be at the position P6 as in the first and second embodiments.

  In addition, although an interval is provided between the upper end of the broken line C46 and the position P5 ', the upper end of the broken line C46 may be at the position P5'.

  Further, in this embodiment, as in the first embodiment, the notch portion KV may be provided in the right side surface portion 30.

  In addition, in each said Example, although the ruled line formed along each broken line was formed with the ruled line pressed from the inner side of the blank, it may be formed with the ruled line pressed from the outer side of the blank. .

  In each of the above embodiments, the folding ruled line is provided along each broken line. However, instead of the folding ruled line, a plurality of linear cuts are provided along the folded line with an interval. May be formed. In that case, in one broken line, a plurality of straight cuts are formed on the same straight line on the broken line. That is, instead of the folding ruled line, a broken line may be formed by a plurality of straight cuts.
