It has a glue margin part 70 which is connected from the side part via a broken line, has a band-like trapezoidal shape, and is bonded to the front side end of the inner side surface of the left side surface part 60. That is, the body portion 10 is formed in a square cylinder shape by bonding the glue margin portion 70 to the front end region of the left side surface portion 60, and includes the front surface portion 30, the right side surface portion 40, the back surface portion 50, The left side part 60 is each side part which comprises the trunk | drum 10, and the surrounding wall 22 of the packaging box 5 is comprised by connecting each part which comprises the trunk | drum 10 sequentially.

  Here, the front portion 30 has a shape in which a protruding portion 36 is provided at the upper end of a square shape (specifically, a vertically long rectangular shape), and the front portion 30 includes an upper side (a broken line C2, A pair of cuts (first cut lines) K1 and K2 are provided downward from the side along C3 (the same applies to the other sides). That is, the cuts K1 and K2 form a right angle with respect to the upper side of the front portion 30 and are formed in the vertical direction, and the upper ends of the cuts K1 and K2 are in contact with the upper side of the front portion 30. In addition, the lower ends of the cuts K1 and K2 are formed to be curved outward in a substantially arc shape to prevent tearing. The cuts K1 and K2 are formed in a straight line in the vertical direction (direction perpendicular to the upper side of the front portion 30) except for the curved portion, and are formed in parallel to each other.

  The cut (first cut) K1 is formed at a position closer to the left side than the center of the front part 30, and the cut (second cut) K2 is formed at a position closer to the right side than the center of the front part 30. Has been. The cuts K1 and K2 are formed symmetrically, and the cuts K1 and K2 are formed by continuous cuts from one end to the other end.

  Further, a fold line (first fold line) C1 is formed in the left-right direction (a direction parallel to the upper side of the front portion 30) between the lower end of the cut K1 and the lower end of the cut K2.

  That is, the front portion 30 has a region between the cut K1 and the cut K2 (the cut K1, the cut K2, the broken line C1, the upper side of the front portion 30 (the portion between the break line L1 and the break line L2) and the cut K3. And a front portion main body 34 which is a region excluding the rotation piece outer portion 32 in the front portion 30.

  In addition, a substantially U-shaped cut (third cut) K3 is formed at the center position in the left-right direction at the boundary between the rotating piece outer side portion 32 and the extension portion 80 of the front portion 30, and thereby the turning piece. A protruding portion 36 that protrudes upward is formed at the upper end of the outer portion 32. That is, the rotating piece outer portion 32 includes a protruding portion 36 and a main body portion 38 that is an area excluding the protruding portion 36 in the rotating piece outer portion 32.

  The cut K3 includes a cut K3a formed in the left-right direction, a cut K3b formed in a substantially vertical direction from an end on the left side of the cut K3a toward the main body 38, and a right side of the cut K3a. The notches K3c and K3c are formed in an obtuse angle with respect to the notch K3a. That is, the cut K3b and the cut K3c are formed to be inclined with respect to the upper side of the front portion 30 so that the distance between the cut K3b and the cut K3c increases. The cut K3b protrudes slightly below the broken line C2, and the cut K3c protrudes slightly below the broken line C3.

  The extension portion 80 is connected from the upper side of the front portion 30 via the polygonal lines C2 and C3, has a substantially square plate shape, and the length in the left-right direction is the left-right direction of the front portion 30 or the back portion 50. It is almost the same as the length (strictly, slightly shorter).

  Further, the extension portion 80 is formed with a break line (second cut line) L1 and a break line (second cut line) L2, and along the boundary line between the extension portion 80 and the holding portion 90, a break line (third line). (Cut line) L3 is formed. That is, the break lines L1, L2, and L3 are planned cutting lines.

  The breaking line L1 is formed from the upper end of the cut K1 of the front part 30 to the side of the tip of the extension 80, and the breaking line L2 is formed from the upper end of the cut K2 of the front part 30 to the side of the tip of the extension 80. The break line L3 is formed between the break line L1 and the tip of the break line L2 (the end portion on the holding portion 90 side).

  That is, the extension portion 80 includes a region between the break line L1 and the break line L2 (the break line L1, the break line L2, the break line L3, and the side portion on the front portion 30 side of the extension portion 80 (the break line L1). And a rotation piece inner side portion 82 which is a region surrounded by a portion between the breaking line L2) and an extension portion main body 84 which is a region excluding the rotation piece inner side portion 82 in the extension portion 80. Yes. The rotating piece outer portion 32 and the rotating piece inner portion 82 constitute the rotating piece 31.

  Note that the distance between the break line L1 and the break line L2 of the break line L1 and the break line L2 decreases from the base end side (the front part 30 side) to the tip end side (the holding part 90 side). It is formed in an inclined shape approaching the center side of the. That is, the break line L1 and the break line L2 form an obtuse angle with respect to the break line L3.

  Further, broken lines C2 and C3 are formed on both sides of the cut K3 at the boundary position between the front portion 30 and the extended portion 80. That is, a fold line (second fold line) C2 is formed at a position between the lower end of the cut K3b and the left side end of the front portion 30, and between the lower end of the cut K3c and the right side end. A broken line (second broken line) C3 is formed at the position, and the broken line C2 and the broken line C3 are formed on the same straight line.

  In addition, in the extension part 80, the breaking line L3 is formed so as to be shifted to the front part 30 side from the broken lines C4, C5, and the length of the rotating piece inner part 82 (the length between the broken lines C2, C3 and the breaking line L3). Is formed shorter than the length of the extension main body 84 (the length between the broken line C2 and the broken line C4, the length between the broken line C3 and the broken line C5), and the extension 80 has an inner end of the broken line C4 and A straight side 80a formed between the corners of the break line L1 and the break line L3, a straight side formed between the inner end of the broken line C5, and the corners of the break line L2 and the break line L3 The side portion 80a is inclined with respect to the broken line C2 so that the distance between the broken line C2 and the broken line C2 decreases from the broken line C4 side to the corner of the broken line L1. Side 80b goes from the broken line C5 side to the corner of break line L2 and break line L3. Distance between have polygonal line C3 are formed to be inclined with respect to fold line C3 to be shorter. That is, the side part 80a is formed on the extension line of the breaking line L1, and the side part 80b is formed on the extension line of the breaking line L2.

  In the state where the packaging box 5 is assembled, as shown in FIGS. 2, 3, 6, and 10, the extension portion 80 is folded inward with respect to the front portion 30 via the fold lines C2 and C3. Yes. In other words, the rotating piece inner portion 82 is folded inward with respect to the rotating piece outer portion 32 via the fold lines C2 and C3.

  Further, the length N1 of the rotating piece inner portion 82 (the length from the base end (end on the side of the broken lines C2 and C3) to the distal end of the rotating piece inner portion 82, that is, from the broken lines C2 and C3 to the breaking line L3. Is the length N2 of the rotating piece outer side portion 32 (the end portion on the side of the broken lines C2, C3) excluding the protruding portion 36 from the base end (end portion on the broken line C1 side) of the rotating piece outer side portion. ), I.e., the length from the broken line C1 to the broken lines C2, C3). Therefore, the broken lines L1, L2, L3 are broken, and the rotating piece outer portion 32 is rotated. By tilting outward together with the piece inner part 82, the turning piece outer part 32 and the turning piece inner part 82 turn through the broken line C1, and the tip of the turning piece inner part 82 draws an arc orbit. However, it rises while projecting to the inside of the front part 30, and the tip of the rotating piece inner part 82 is the bent piece 134. By bending piece 134 is pushed up by the tip of the turning piece inner portion 82 in contact with the end (post theory for details) lid 130 is pushed upward.

  Further, the length obtained by subtracting the length N2 of the rotating piece outer side portion 32 from the length N1 of the rotating piece inner side portion 82 is shorter than the length N2, and accordingly, the rotating piece inner portion 82 and the rotating piece. In a state where the outer portion 32 is overlapped, the length protruding from the base end of the rotating piece outer portion 32 of the rotating piece inner portion 82 (the length obtained by subtracting the length N2 from the length N1) is the rotating piece. It is shorter than the length N2 of the outer portion 32, and the bent piece 134 can be pushed up with a small force by the principle of leverage. That is, the lid 130 can be pushed up even if the force for rotating the rotating piece outer portion 32 is small.

  The holding portion 90 is connected from the side of the tip of the extension portion 80 (the end opposite to the front portion 30) via the fold lines C4 and C5 (fifth fold line), and is approximately at the center of the substantially rectangular shape. A circular (specifically, elliptical) hole portion is formed, and the corner portion at the tip on the right side is cut out in an arc shape. That is, the holding portion 90 in which the hole portion 90 a is formed in the center and the notch portion 90 b is formed in the corner portion at the tip on the right side is connected to the side portion at the tip of the extension portion 80.

  In addition, a broken line is formed at a position other than the breaking line L3 at the boundary position between the holding portion 90 and the extended portion 80. That is, a broken line (fifth broken line) C4 is formed on the left side of the breaking line L3, a broken line (fifth broken line) C5 is formed on the right side of the breaking line L3, and the broken line C4 and the broken line C5 are Are formed on the same straight line. In the unfolded state of the packaging box 5, the breaking line L3 is formed so as to be shifted to the folding lines C2, C3 in the direction perpendicular to the folding lines C2, C3 with respect to the folding lines C4, C5 (that is, the holding portion 90). In the state in which the extension portion 80 and the extension portion 80 are deployed in a single flat plate shape, the breaking line L3 is formed so as to be shifted to the folding lines C2 and C3 with respect to the folding lines C4 and C5). At the end, a portion between the polygonal line C4 and the polygonal line C5 is formed so as to protrude from the polygonal lines C4 and C5. Thus, since the broken lines C4 and C5 and the break line L3 are formed so as to be shifted, the break line L3 automatically breaks when the holding part 90 is bent with respect to the extension part 80. Thus, there is no need to break the breaking line L3 when the rotating piece 31 is rotated. In addition, since the broken lines C4 and C5 and the break line L3 are formed so as to be shifted, when the holding portion 90 is bent with respect to the extension portion 80, there is no gap between the tip of the inner plate portion 82 and the holding portion 90. The interval is provided, and when the rotating piece 31 rotates, the tip of the inner plate portion 82 does not come into contact with the holding portion 90 and the holding portion 90 does not get in the way. Further, by not forming the break line L3 and the broken lines C4 and C5 on the same straight line, it is possible to prevent the broken lines C4 and C5 from being broken when the break line L3 is broken.

  In the state in which the packaging box 5 is assembled, as shown in FIGS. 2 and 3, the holding portion 90 is bent inward with respect to the extension portion 80 via the fold lines C4 and C5 and provided approximately horizontally. As shown in FIG. 10, the bottle B can be held by passing the neck of the bottle B stored in the packaging box 5 through the hole 90a.

It has a shape in which a substantially square shape is continuously provided at the tip of a trapezoidal shape perpendicular to the upper side of the head and a front end 30 side end portion cut out in parallel with the rear side portion. That is, the upper flap portion 110 has a side portion 110a perpendicular to the upper side of the right side surface portion 40 on the front side, and the folded piece 134 has the extension portion 80 and the side portion 110a when the lid portion 130 is closed. It will be sandwiched between the two. The length from the base side (the side on the right side 60) to the tip side (the side opposite to the right side 60) of the upper flap 110 is the right and left of the front part 30 and the back part 50. It is formed to have a length of ½ or less of the length in the direction.

  The upper flap 120 is connected to the upper side of the left side surface 60 via a broken line, and has a substantially trapezoidal shape (one side (side on the back side 50) of both sides) on the left side. A shape in which a substantially square shape is continuously provided at the tip of a trapezoidal shape perpendicular to the upper side of the surface portion 60 from the end portion on the front surface portion 30 side, that is, with respect to the upper flap portion 110 The upper flap 120 has a symmetric (axisymmetric) shape, and has a side 120a perpendicular to the upper side of the left side 60 on the front side, and the folded piece 134 when the lid 130 is closed. Is sandwiched between the extension portion 80 and the side portion 120a.

It is formed to have a length of ½ or less of the length in the direction.

  Further, the lid portion 130 includes a lid plate portion 132 provided continuously from the upper side of the back surface portion 50 via a fold line C8, and a fold line from a side portion at the tip of the lid plate portion 132 (side portion opposite to the back surface portion 50). And a bent piece 134 provided continuously through C9.

  The cover plate portion 132 has a rectangular plate shape, and the length in the left-right direction is substantially the same as the length in the left-right direction of the front portion 30 and the back portion 50. The length from the side part 50 side to the side part at the tip (that is, the length from the broken line C8 to the broken line C9) is substantially the same as the lateral length of the right side part 40 and the left side part 60. .

  Further, the bent piece 134 includes a side portion along the fold line C9, a pair of side portions perpendicular to the fold line C9 from the end portions on both sides of the fold line C9, and a side opposite to the side portion along the fold line C9. It has a shape in which rounds are provided at the corners on both sides on the front end side in a quadrilateral shape that is composed of sides inclined with respect to the direction of the polygonal line C9. That is, the bent piece 134 includes a side part 134a along the broken line C9, a straight side part 134b formed at right angles to the side part 134a from the right side surface end of the side part 134a, and a side part. A substantially arc-shaped side portion 134c continuously provided from an end portion of the side portion 134b opposite to the side portion 134a side, and a linear shape provided continuously from an end portion of the side portion 134c opposite to the side portion 134b side. A side part 134d that is inclined with respect to the direction of the side part 134a, a substantially arc-shaped side part 134e that is provided continuously from an end of the side part 134d opposite to the side part 134c, and a side part 134e is formed of a straight side portion 134f that is connected from the end opposite to the side portion 134d and is formed at right angles to the side portion 134a.

  The side portion 134d is inclined with respect to the fold line C9 so that the distance from the fold line C9 increases toward the left side, and the bent piece 134 has a shape in which the tip on the left side protrudes. .

  Note that the length of the bent piece 134 in the left-right direction (the length of the side portion 134a) is a length that allows the bent piece 134 to be inserted into the extension portion 80 when the lid portion 130 is closed. As described above, the left end of the bent piece 134 has a protruding shape so that the bent piece 134 can be inserted into the extension 80 from the protruding portion. The bending piece 134 can be easily inserted into the extension 80.

  Further, the length (maximum length) N3 from the base end to the tip end of the bent piece 134 is formed to be shorter than the length N1 of the rotating piece inner portion 82.

  Next, the bottom surface portion 200 will be described. The bottom surface part 200 includes a piece part 210, a piece part 220, a piece part 230, and a piece part 240.

  The piece portion 210 is connected from the lower side of the front portion 30 via a broken line, and has a substantially rectangular shape at the tip of a trapezoidal shape (a trapezoidal shape in which the side sides on both sides are inclined with respect to the lower side portion of the front portion 30). It has a continuous shape. The piece 220 is connected to the lower side of the right side 40 via a broken line, and the trapezoidal shape (one side (the side on the front part 30 side) of the sides on both sides is the right side 40. The trapezoidal shape at a right angle to the side of the lower end of the shape) has a shape in which a substantially rectangular shape is continuously provided. Moreover, the piece part 230 is continuously provided from the side part of the lower end of the back surface part 50 via a broken line, and has a shape in which a substantially rectangular cutout part is formed on the square front end side. Moreover, the piece part 240 is continuously provided from the side part of the lower end of the left side part 60 via a broken line, and has a symmetrical (line-symmetric) shape with respect to the piece part 220 in the unfolded state of the packaging box 5. Such a bottom surface portion 200 is called a B-type bottom assembly type, and is also called an American rock or a hell bottom.

  In the above, a crease line is formed at the portion of the broken line, specifically, a ruled line pressed from the outer surface of the blank is formed. For example, the broken lines C1, C2, C3, C4, and C5 are formed with ruled lines from the front surface in the state of FIG.

  Next, the usage method of the packaging box 5 of the said structure is demonstrated. Since the packaging box 5 is configured as described above, the extension portion 80, the holding portion 90, the lid portion 130, and the upper flap portions 110 and 120 extend above the trunk portion 10 and constitute the bottom surface portion 200. The packaging box 5 can be folded flat by folding the barrel 10 with the pieces 210, 220, 230, 240 extending below the barrel 10. In the state where the packaging box 5 is folded, the front portion 30 and the right side surface portion 40 of the trunk portion 10 are substantially parallel, and the back surface portion 50 and the left side surface portion 60 are substantially parallel.

  In order to assemble the packaging box 5 from the folded state, the bottom part 200 is assembled so that the bottle B can be stored. That is, the bottom part 200 is assembled by inserting the tip of the piece 210 into the gap formed by the piece 230 and the pieces 220 and 240 in a state where the pieces 220 and 240 are overlapped from the bottom side of the piece 230. It is done.

  Thereafter, the bottle B is accommodated in the body portion 10, the extension portion 80 is folded inward with respect to the front portion 30, and then the neck portion of the bottle B is inserted into the hole portion 90 a of the holding portion 90 and held. The portion 90 is substantially horizontal. By making the holding portion 90 substantially horizontal, the extension portion 80 can be folded back to the inside of the front portion 30 so as to be substantially parallel to the front portion 30, and the storage space of the packaging box is restricted. The fear can be made smaller. Further, when the holding portion 90 is substantially horizontal, the holding portion 90 is substantially perpendicular to the extension portion 80, and the holding portion 90 is bent with respect to the extension portion 80. Therefore, the holding portion 90 is bent with respect to the extension portion 80. When this occurs, the breaking line L3 breaks. At this time, the packaging box 5 itself is in the state shown in FIGS. 2 and 3 (that is, the bottle is stored in FIGS. 2 and 3).

  When storing the bottle B, as shown in FIG. 6, the lid 130 and the upper flaps 110 and 120 are opened with respect to the body 10 so that the bottle B can be easily stored. Is a state in which the bent piece 134 is bent with respect to the cover plate portion 132, and the extension portion 80 is bent with respect to the front portion 30 (the folding lines C2 and C3 are mountain-folded when viewed from the outside) and held. It is preferable that the portion 90 is bent with respect to the extended portion 80 (the broken lines C4 and C5 are valley-folded when viewed from the outside).

  Thereafter, the upper flap portions 110 and 120 are rotated inward (the upper flap portion 110 is rotated inward with respect to the right side surface portion 40, and the upper flap portion 120 is rotated inward with respect to the left side surface portion 60). Further, the lid portion 130 is turned inward with respect to the back surface portion 50 in a state where the bent piece 134 is bent inward with respect to the lid plate portion 132, and the bent piece 134 is inserted into the extension portion 80. As a result, the packaging box 5 is closed. When the lid 130 is in the closed state, the state shown in FIGS. 1 and 10A is obtained.

  In the closed state of the lid portion 130, the upper end of the rotating piece inner portion 82 and the upper end of the bent piece 134 are substantially coincided with each other in the height direction. Since the length N3 is shorter than the length N1 of the rotating piece inner portion 82, the lower end of the rotating piece inner portion 82 is positioned below the lower end of the bent piece 134 in the height direction. doing. That is, the tip of the rotating piece inner portion 82 protrudes downward (or downward) from the lower end of the bent piece 134. In addition, since the rotating piece inner portion 82 pushes up the bent piece 134, at least the tip of the rotating piece inner portion 82 is a region where the rotating piece inner portion 82 faces the bent piece 134 (the rotating piece inner portion 82. 82 may be a region in contact with it) (the region shown by hatching in FIG. 4) as long as it projects downward from the lower end.

  When the packaging box 5 is stored, the packaging box 5 may be folded flat, but the packaging box 5 may be assembled as shown in FIG.

  Next, when opening the packaging box 5 in the closed state, as shown in FIG. 7, a finger is put on the protruding portion 36 of the rotating piece outer portion 32, and the rotating piece outer portion 32 is connected via the broken line C <b> 1. Rotate outward. Then, as the rotating piece outer portion 32 rotates and tilts with respect to the vertical direction, the rotating piece inner portion 82 tilts with respect to the vertical direction, and as the rotating piece inner portion 82 tilts, As shown in FIG. 10B, the lower end of the bent piece 134 is pushed to the back side by the rotating piece inner portion 82. When the turning piece inner portion 82 is inclined, the breaking lines L 1 and L 2 are broken and the turning piece inner portion 82 is separated from the extension portion main body 84. In the operation of rotating the rotating piece outer portion 32, the breaking lines L1 and L2 can be broken, so that another operation for breaking the breaking lines L1 and L2 is not required.

  Thereafter, by further rotating the rotating piece outer portion 32, the lower end of the bent piece 134 is pushed up by the rotating piece inner portion 82 as shown in FIG. 10 (c) and FIG. Then, by further rotating the rotating piece outer portion 32, the lower end of the bent piece 134 is pushed up by the rotating piece inner portion 82 as shown in FIGS. And a large gap are formed between the upper flap portions 110 and 120. Since a large gap is formed between the lid plate portion 132 and the upper flap portions 110 and 120, the lid portion 130 is opened by placing the fingers on the left and right sides of the lid plate portion 132 and pulling upward. can do.

  Since the side part 134d at the tip of the bent piece 134 is inclined with respect to the direction of the side part 134a, when the bent piece 134 is lifted by the rotating side inner part 82, the lid plate part 132 and Since the gap between the upper flap portions 120 is larger than the gap between the lid plate portion 132 and the upper flap portion 110, the side on the left side of the lid plate 132 is hooked with a finger rather than the side on the right side. It is easy to use and is suitable for catching the thumb, which is a thick finger among the five fingers.

  10A corresponds to the state of FIG. 7, FIG. 10C corresponds to the state of FIG. 8, and FIG. 10D corresponds to the state of FIG.

  Moreover, in the packaging box 5, when opening the cover part 130, if the rotation piece 31 is rotated, the breaking lines L1 and L2 will be broken, but the cover part 130 is closed again and the rotation piece 31 is rotated. Thus, the opening operation of the lid portion 130 can be performed, so that the lid portion 130 can be repeatedly opened and closed.

  In order to take out the stored bottle B, the state where the neck portion of the bottle B is inserted into the hole 90a of the holding portion 90 with the lid portion 130 opened is released to the state shown in FIG. In order to release the state where the neck of the bottle B is inserted through the hole 90a, the holder 90 is pulled up by placing a finger on the notch 90b of the holder 90.

  In the above description, the holding unit 90 is provided. However, the configuration of the holding unit 90 may be omitted, or the holding unit 90 may be omitted and the extension body 84 may be omitted. It is good. When the configuration of the holding portion 90 is omitted, in the extension portion 80, the rotating piece inner side portion 82 is connected to the extension portion main body 84 via the break lines L1 and L2, and the break line L3 is not provided.

  As described above, according to the packaging box 5 according to the present invention, the bent piece 134 is pushed up by the turning piece inner portion 82 by turning the turning piece outer portion 32 outward through the broken line C1. Therefore, the lid 130 can be easily opened. In particular, when the rotating piece inner portion 82 and the rotating piece outer portion 32 overlap each other, the length protruding from the base end of the rotating piece outer portion 32 of the rotating piece inner portion 82 (the length from the length N1 to the length). The length obtained by subtracting N2 is shorter than the length N2 of the rotating piece outer portion 32, and the bent piece 134 can be pushed up with a small force by the principle of leverage.

  Further, when closing the lid portion 130, the extension portion 80 is folded back with respect to the front portion 30, and the holding portion 90 may be in a substantially horizontal state, so that the operation of closing the lid portion can be easily performed. it can. This is the same when the holding unit 90 is omitted or when the holding unit 90 and the extension main body 84 are omitted. When the holding unit 90 is omitted, when the lid 130 is closed, the extension unit is omitted. 80 may be in a state of being folded back with respect to the front portion 30, and even when the holding portion 90 and the extension portion main body 84 are omitted, the rotating piece inner portion 82 is folded back with respect to the front portion 30. Therefore, the operation of closing the lid can be easily performed.

  In the closed state of the packaging box 5, the rotating piece outer portion 32 is flush with the front portion main body 34, and the extension portion 80 (particularly, the turning piece inner portion 82) is stored in the packaging box 5. Therefore, members for opening the packaging box (the rotating piece outer portion 32 and the rotating piece inner portion 82) do not protrude to the outside. This is the same when the holding unit 90 is omitted or when the holding unit 90 and the extension main body 84 are omitted.

  In the closed state of the packaging box 5, the rotating piece outer portion 32 is flush with the front portion main body 34, and the extension portion 80 (particularly, the turning piece inner portion 82) is located in front of the packaging box 5. Since it is in a state of being folded back with respect to the portion 30, it is possible to reduce the possibility that members for opening the packaging box (the rotating piece outer portion 32 and the rotating piece inner portion 82) will protrude into the packaging box 5. The possibility that the storage space of the packaging box is restricted can be reduced. This also applies to the configuration in which the holding unit 90 is omitted or the configuration in which the holding unit 90 and the extension main body 84 are omitted. In particular, by adopting a configuration in which the holding portion 90 is provided, the holding portion 90 is maintained in a substantially horizontal direction by inserting the neck portion of the bottle B into the hole portion 90 a, and the extension portion 80 is in relation to the front portion 30. Since the folded state can be maintained, the possibility that the extension 80 protrudes to the inside of the packaging box 5 is further reduced.

  Moreover, since the rotation piece inner side part 82 is continuously provided by the extension part main body 84 via the breaking lines L1 and L2, and is continuously provided by the holding | maintenance part 90 via the breaking line L3, the breaking line must be broken. Since the rotating piece 31 (the rotating piece composed of the rotating piece outer portion 32 and the rotating piece inner portion 82) cannot be rotated, the rotating piece 31 is inadvertently rotated and the lid portion 130 is moved. It is not lifted with respect to the trunk 10. This is the same even when the configuration of the holding portion 90 is omitted, since the rotating piece inner portion 82 is connected to the extension portion main body 84 via the break lines L1 and L2.

  Further, the holding portion 90 is supported at a substantially right angle with respect to the front portion 30 by being bent inward with respect to the extension portion 80 via the broken lines C4 and C5, and the packaging box is placed in the hole portion 90a of the holding portion 90. Since the bottle B is held by passing the neck portion of the bottle B stored in the bottle 5, the bottle B is inclined to obstruct the operation of the rotating piece inner portion 82, or the bottle B is moved to the inner portion of the rotating piece during transportation. There is no possibility of breaking the break lines L1, L2, and L3 by colliding with 82.

  Further, when operating the rotary piece inner portion 82, a finger is put on the protruding portion 36 of the rotary piece outer portion 32, and the rotary piece superposed on the rotary piece outer portion 32 and the rotary piece outer portion 32. Since the inner part 82 can be pulled down to the outside, the lid part 130 can be opened more easily.

  Even when the opening operation is once performed on the packaging box 5, the lid portion 130 can be opened again by closing the lid portion 130 and rotating the rotating piece 31. Can be repeatedly opened and closed.

  In the above description, the break line L3 is formed so as to be shifted from the broken lines C4 and C5. However, the break line L3 may be on an extension line of the broken lines C4 and C5. In that case, when the holding part 90 is bent with respect to the extension part 80, the breaking line L3 does not break, so when rotating the rotating piece outer part 32 (which may be the rotating piece 31). The breaking line L3 is broken along with the breaking lines L1 and L2. In that case, when the inner side plate part 82 is inclined with respect to the extension part main body 84, the lower end of the inner side plate part 82 protrudes to the back side from the extension part 80. When it is made to incline with respect to, the fracture line L3 breaks.

  In the above description, the protruding portion 36 is provided. However, the configuration of the protruding portion 36 may be omitted. In that case, the cut K3 is omitted, the broken line C2 and the broken line C3 are connected, and one broken line is provided between the front portion 30 and the extension portion 80.

  Moreover, in the said Example, although the trunk | drum 10 was taken as the square cylinder shape which has the front part 30, the right side part 40, the back part 50, and the left side part 60, with respect to a front part and a front part, And a cylindrical body having a back surface portion facing each other, for example, a hexagonal cylindrical body or an octagonal cylindrical body.

  In the above description, the body portion 10 is configured by sequentially connecting the respective portions constituting the body portion 10, but the bottom surface portion is configured by one member (sheet-like member), and the body portion May be configured to be provided continuously from each side of the bottom surface portion, and in the above description, the breaking line L3 that defines the side portion on the distal end side of the rotating piece inner portion 82 is an extension portion. Although described as being provided at the boundary position between 80 and the holding portion 90, a break line that divides the side portion on the distal end side of the inner side of the rotating piece may be provided inside the extension portion.

  That is, as shown in FIG. 11, the packaging box 5 ′ includes a substantially rectangular bottom surface portion 200, a front portion 30 that is provided continuously from a side portion on the front side of the bottom surface portion 200 via a broken line, and a front portion 30.

  Here, in the packaging box 5 ′, a pair of cuts (first cut lines) K1 and K2 are provided downward from the upper side of the front portion 30, and a broken line (first line) is formed between the lower end of the cut K1 and the lower end of the cut K2. One broken line C1 is formed in the left-right direction (direction parallel to the upper side of the front portion 30).

  Further, in the edge plate portion 75, cuts (cut lines) K4 and K5 are formed, the cut K4 is formed continuously from the cut K1, and the cut K5 is formed continuously from the cut K2. The cuts K4 and K5 are formed in the front-rear direction in the assembled state of the packaging box 5 '.

  The extension 80 is formed with a break line (second cut line) L1 and a break line (second cut line) L2, and further, a lower end of the break line L1 and a lower end of the break line L2 (packaging box 5 ′ The broken line L3 is formed in the left-right direction between the lower end portion in the assembled state. That is, the breaking line L3 is continuously provided from the lower end of the breaking line L1 and the lower end of the breaking line L2.

  Further, in the packaging box 5 ′, the length N1 of the rotating piece inner portion 82 (the length from the base end (end portion on the broken line C2 side) to the tip of the rotating piece inner portion 82, that is, the broken line C2 to the breaking line. The length up to L3) is the length N2 of the rotating piece outer portion 32 (the length from the proximal end (end portion on the broken line C1 side) of the rotating piece outer portion to the distal end (end portion on the broken line C2 side), That is, it is formed longer than the length of the polygonal line C1 to the polygonal line C2.

  Further, in the packaging box 5 ′, the length obtained by subtracting the length N2 of the rotary piece outer side portion 32 from the length N1 of the rotary piece inner side portion 82 is shorter than the length N2, and thereby the inner side of the rotary piece. In a state where the portion 82 and the rotating piece outer portion 32 overlap each other, the length protruding from the base end of the rotating piece outer portion 32 of the rotating piece inner portion 82 (the length obtained by subtracting the length N2 from the length N1). ) Is shorter than the length N2 of the rotating piece outer portion 32, and the bent piece 134 can be pushed up with a small force by the principle of leverage. That is, the lid 130 can be pushed up even if the force for rotating the rotating piece outer portion 32 is small.

  Further, the length (maximum length) N3 from the proximal end to the distal end of the bent piece 134 is formed to be shorter than the length N1 of the rotating piece inner portion 82. The bent piece 134 has a shape in which the tip on the left side protrudes, as in the case of the first embodiment.

  Further, in order to close the lid portion 130, the upper flap portions 110 and 120 are turned inward, and the back portion 50 is further folded while the lid portion 130 is bent inward with respect to the lid plate portion 132. The bent piece 134 is inserted into the extension 80.

  In the closed state of the lid portion 130, the upper end of the rotating piece inner portion 82 and the upper end of the bent piece 134 are substantially coincided with each other in the height direction. Since the length N3 is shorter than the length N1 of the rotating piece inner portion 82, the lower end of the rotating piece inner portion 82 is positioned below the lower end of the bent piece 134 in the height direction. doing. That is, the tip of the rotating piece inner portion 82 protrudes downward (or downward) from the lower end of the bent piece 134. In addition, since the rotating piece inner portion 82 pushes up the bent piece 134, at least the tip of the rotating piece inner portion 82 is a region where the rotating piece inner portion 82 faces the hatched piece 134 (in FIG. 11, hatching). It suffices if it protrudes below the lower end of the region shown.

  Further, when opening the closed packaging box 5 ′, the rotating piece outer side portion 32 is rotated outward through the broken line C <b> 1.

When the turning piece inner portion 82 is inclined, the breaking lines L1 and L2 break and the breaking line L3 breaks, and the turning piece inner portion 82 is separated from the extension main body 84. That is, since the lower end of the rotating piece inner portion 82 protrudes to the back side from the extension portion 80 when the rotating piece inner portion 82 is inclined, the breaking line L3 is also broken. In the operation of rotating the rotating piece outer portion 32, the breaking lines L1, L2, and L3 can be broken, so that another operation for breaking the breaking lines L1, L2, and L3 is not required.

  Thereafter, by further rotating the rotating piece outer portion 32, the lower end of the bent piece 134 is pushed up by the rotating piece inner portion 82. Then, by further rotating the rotating piece outer portion 32, the lower end of the bent piece 134 is pushed up by the rotating piece inner portion 82, and there is a gap between the lid plate portion 132 and the upper flap portions 110 and 120. Largely formed. Since a large gap is formed between the lid plate portion 132 and the upper flap portions 110 and 120, the lid portion 130 is opened by placing the fingers on the left and right sides of the lid plate portion 132 and pulling upward. can do.

  Also by the packaging box 5 ′ shown in FIG. 11, the turning piece inner portion 82 can push up the bent piece 134 by turning the turning piece outer portion 32 outward through the broken line C1, so that it is easy. The lid portion 130 can be opened. In particular, when the rotating piece inner portion 82 and the rotating piece outer portion 32 overlap each other, the length protruding from the base end of the rotating piece outer portion 32 of the rotating piece inner portion 82 (the length from the length N1 to the length). The length obtained by subtracting N2 is shorter than the length N2 of the rotating piece outer portion 32, and the bent piece 134 can be pushed up with a small force by the principle of leverage.

  Further, in the packaging box 5 ′, when the lid portion 130 is closed, the extension portion 80 is fixed to the back side of the front portion 30, so that the bent piece 134 may be inserted into the extension portion 80, The operation of closing the part can be easily performed.

  In the closed state of the packaging box 5 ′, the rotating piece outer portion 32 is flush with the front body 34, and the extension 80 (particularly, the rotating piece inner portion 82) is in the packaging box 5 ′. Therefore, members for opening the packaging box (the rotating piece outer side portion 32 and the rotating piece inner side portion 82) do not protrude to the outside.

  In the closed state of the packaging box 5 ′, the rotating piece outer portion 32 is flush with the front portion main body 34, and the extension portion 80 (particularly, the turning piece inner portion 82) is in the packaging box 5. Since it is in a state of being folded with respect to the front part 30, there is a risk that members for opening the packaging box (the rotating piece outer portion 32 and the rotating piece inner portion 82) may protrude into the packaging box 5 '. The possibility of restricting the storage space of the packaging box can be reduced. In particular, by inserting the protrusions 80a and 80b into the holes formed by the cuts K201 and K202, the extension 80 is fixed to the back side of the front portion 30, so that the extension 80 is inside the packaging box 5 '. There is no risk of protruding.

  Further, in the packaging box 5 ′, the rotating piece inner portion 82 is connected to the extension main body 84 via the breaking lines L1, L2, and L3, so that the rotating piece 31 ( Since the rotating piece consisting of the rotating piece outer portion 32 and the rotating piece inner portion 82 cannot be rotated, the rotating piece 31 is inadvertently rotated and the lid portion 130 is moved relative to the trunk portion 10. Will not be lifted.

  Even when the opening operation is once performed on the packaging box 5 ′, the lid 130 can be opened again by closing the lid 130 and rotating the rotating piece 31. 130 can be opened and closed repeatedly.

  In the packaging box 5 ′, the extension portion main body 84 may be omitted from the extension portion 80. In this case, only the rotating piece inner portion 82 is continuously provided from the edge plate portion 75a. Also in the plate part 75, the configuration of the edge plate part 75b is omitted.

  In addition, in the packaging box 5 of Example 1, it is good also as a structure which provides an edge-plate part between the front part 30 and the extension part 80 like the packaging box 5 'of Example 2. FIG. In this case, the configuration of the protruding portion 36 may be omitted as in the packaging box 5 ′, or the protruding portion 36 may be provided. When the projecting portion 36 is provided, the notch K3a of the notch K3 constituting the projecting portion 36 is provided on the extension line of the broken line between the edge plate portion and the extension portion 80, and the front portion is provided between the notch K3b and the notch K3c. The broken line between 30 and the edge plate portion is not provided. In addition, in the packaging box 5 of Example 1, when providing an edge plate part between the front part 30 and the extension part 80, in the case of the structure which abbreviate | omits the structure of the extension part main body 84 from the extension part 80, an edge plate part Is provided only on the side portion of the rotating piece inner side portion 82 on the edge plate portion side.

  In the second embodiment, the bottom surface portion 200 has a substantially square shape having four sides, and the front surface portion 30, the right side surface portion 40, the back surface portion 50, and the left side surface portion 60 constituting the body portion 10 are each side of the bottom surface portion 200. However, the number of the side portions in the bottom surface portion 200 is other than four, and the side portions (side portions on the front side and side portions on the back side) are opposed to each other, and the trunk portion is configured. It is good also as a structure with which each part to be continued from each edge | side of a bottom face part. For example, the bottom part 200 may be a hexagonal or octagonal case.
