  The present invention relates to a wound body storage box, a wound body storage box intermediate body, and a wound body storage box, in particular, a wound body storage box provided with a flap for separating a drawn long object from a main body, a wound body housing. The present invention relates to a box intermediate body and a container box containing a wound body.

  Generally, a wrap film used for food packaging and the like is accommodated in an elongated rectangular box as a roll wound in a roll. The storage box includes a main body having a rectangular parallelepiped one surface open, and a lid opening and closing the opening of the main body. The roll-shaped wrap film is accommodated in the main body. When using wrap film, it is general to open the lid, pull out the required amount of wrap film from the roll, close the lid, and cut the wrap film with a cutting blade provided at the tip of the lid. It is After cutting the wrap film, so-called unrolling may occur in which the leading end of the drawn wrap film adheres to the roll. Also, when the wrap film is pulled out of the roll, the roll may be pulled out of the opening by being pulled out of the wrap film. In order to suppress such unwinding and / or protrusion of the roll, there is a storage box provided with a pressing plate at the side of the main body opposite to the side where the lid is connected (see, for example, Patent Document 1). ).

  On the other hand, there are cases in which a storage box containing a roll-shaped wrap film is provided with a flap for separating the pulled-out wrap film from the main body in order to make it easy to pick the wrap film. The flap is formed, for example, by making a cut in the upper portion of the front plate of the main body, separating it from the main body at the boundary of the cut, and cutting up (see, for example, Patent Document 2).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the drawings, the same or corresponding members are denoted by the same or similar reference numerals, and the redundant description will be omitted.

  First, referring to FIG. 1, according to the embodiment of the present invention, a wrap carton 1 as a wound body storage box, and a wound body containing a wrap roll 91r as a wound body housed in the wrap carton 1 A wrapped carton 100 as a box is described. FIG. 1 is a front perspective view of a carton 100 with wrap. The wrap roll 91r is formed in a roll shape by wrapping a wrap film 91f as a thin film-like long material around a shaft 91a around a cylindrical core. In the following description, when the external shapes of the wrap roll 91 r and the wrap film 91 f are not distinguished, they are collectively referred to as “wrap 91”. In the present embodiment, the wrap film 91 f is formed to have a thickness of 5 to 20 μm using polyvinylidene chloride as a raw material. The wrap carton 1 is provided with a main body portion 10 for housing the wrap roll 91 r, a lid portion 20 connected to the main body portion 10, a pressing plate 31, and a flap 41. In addition, FIG. 1 has shown the state which unseal | opened and the cover part 20 was opened.

  The main body portion 10 is a box in which one of the elongated surfaces is an opening surface 10 h with respect to a rectangular parallelepiped large enough to accommodate the unused wrap roll 91 r. The size of the main body portion 10 is formed as small as possible while forming a gap that does not prevent the accommodated unused wrap roll 91r from rotating about the axis 91a, and in the present embodiment, the length It is formed in a size of 310 mm, height 44 mm, and depth 44 mm. The main body portion 10 has a front plate 12, a bottom plate 13 and a rear plate 14 which constitute side surfaces of a rectangular parallelepiped in cooperation with the opening surface 10h, and two side plates 15 which constitute end faces of the rectangular parallelepiped. The bottom plate 13 is opposed to the opening surface 10 h. The front plate 12 and the rear plate 14 are orthogonal to the opening surface 10 h and the bottom plate 13. Although the side plate 15 is typically formed in a square, it may be a rectangle having different vertical and horizontal lengths. In the following description, it may be described that the bottom plate 13 side is down and the opening surface 10 h is up based on a state where the bottom plate 13 is placed on a horizontal surface. At the central portion of the upper end of the side plate 15, there is provided a protrusion 15p formed by folding back a small piece extending upward by about 3 mm. The projections 15 p are provided on the upper ends of the two side plates 15.

  The lid portion 20 is a member that closes the opening surface 10 h of the main body portion 10. The lid portion 20 has a lid plate 21, an eyelid lid piece 22, a cutting blade 23, and a side lid piece 25. The cover plate 21 is a rectangular flat plate member having substantially the same size as the opening surface 10 h, and can be formed into a rectangular parallelepiped in which the main body portion 10 is closed by fitting the cover plate 21 to the opening surface 10 h. The cover plate 21 is larger by the thickness of the cover 22 and the thickness of the side cover 25 so that a gap which does not prevent the opening and closing of the cover 20 is formed. It is meant to include large cases. In the cover plate 21, one side parallel to the direction in which the axis 91 a of the wrap roll 91 r extends (hereinafter, referred to as “axial direction D”) is connected at the rear plate end 18 of the main body 10. In other words, the main body portion 10 and the cover plate 21 are connected via the rear plate end side 18. The rear plate end side 18 is an end side of the rear plate 14 in a portion where the rear plate 14 and the opening surface 10 h intersect. The cover plate 21 is configured to be able to pivot relative to the main body 10 with the rear plate end side 18 as the rotation axis.

  The lid 22 is perpendicular to the lid 21 via the bent side 21 f and extends toward the bottom 13 when the lid 20 is closed. The height of each end of the lid 22 in the axial direction D (the length in the direction of the short side of the rectangular front plate 12) is about 1/2 of the length in the direction of the short side of the front plate 12 The height of the central portion is about 3⁄4 of the length of the front plate 12 in the short side direction. As the tip side 22t opposed to the bending side 21f moves from the center in the axial direction D to each end, the distance between the bending side 21f and the tip side 22t in the direction orthogonal to the axial direction D becomes short. It is formed to be With such a configuration, the tip side 22t opposite to the bent side 21f is formed in a V-shape. When the lid portion 20 is closed, the lid portion 22 overlaps the outside of the front plate 12 along the front plate 12 and covers the upper portion of the front plate 12 in a pentagonal shape. The length of the axial direction D of the weir cover piece 22 is slightly longer than that of the front plate 12 and is longer than the width of the wrap 91 accommodated in the main body 10. Thereby, the eyelid cover piece 22 is configured to be able to sandwich the wrap film 91 f drawn out of the main body portion 10 with the front plate 12 over the entire width thereof. A cutting blade 23 for cutting the wrap film 91 f is attached to the tip side 22 t of the eyelid cover piece 22. The cutting blade 23 is provided in a V-shape along the tip side 22t so that the cutting edge comes out of the tip side 22t.

The side cover piece 25 is provided orthogonal to both the cover plate 21 and the cover piece 22. A total of two side lid pieces 25 are provided at both ends of the lid plate 21 (the lid lid piece 22). The side cover piece 25 has a basic shape whose long side is the same length as the short side of the cover plate 21 and whose short side is the height at the central portion of the cover piece 22 (from the V-shaped tip to the bending side 21 f It is formed in a rectangle of approximately the same length as the shortest distance). The side cover piece 25 is fixed to the joint piece 22 j connected to the cover piece 22 with an adhesive. A recess 25 d is formed between the joint piece 22 j and the cover plate 21 inside the side cover piece 25. When the lid 20 is closed, the protrusion 15p provided at the upper end of the side plate 15 is fitted in the recess 25d. The lid portion 20 configured as described above covers the opening surface 10 h of the main body portion 10 when the lid portion 20 is closed, and the lid portion 22 covers the upper portion of the front plate 12.

  The pressing plate 31 is a member for preventing the unwinding of the wrap film 91 f drawn from the wrap roll 91 r housed in the main body portion 10. Rewinding of the wrap film 91f is a phenomenon in which the leading end of the wrap film 91f which is once pulled out from the wrap roll 91r adheres to the wrap roll 91r. Further, the pressing plate 31 also contributes to preventing the wrap roll 91 r from jumping out of the main body portion 10. The pressing plate 31 is a flat member which partially covers the opening surface 10 h while leaving at least a drawing space 10 s when drawing the wrap film 91 f from the wrap roll 91 r accommodated in the main body portion 10. The drawing space 10s preferably has a size that does not prevent the drawing of the wrap film 91f and is formed to be thinner than the diameter of the core on which the wrap film 91f is wound. With this configuration, it is possible to prevent the wrap roll 91r (or the core) from jumping out of the main body 10 until the wrap film 91f is finished using. The wrap roll 91r accommodated in the main body 10 may have no winding core. The pressing plate 31 is connected to the front plate end 19 of the main body 10. In other words, the main body portion 10 and the pressing plate 31 are connected via the front plate end side 19. The front plate end side 19 is an end side of the front plate 12 in a portion where the front plate 12 and the opening surface 10 h intersect when assuming that the pressing plate 31 is not provided, and is a side parallel to the axial direction D . The front plate end side 19 forms a boundary between the pressing plate 31 and the main body portion 10, and corresponds to a pressing boundary line.

  In the present embodiment, the pressure plate 31 is formed to have a size that does not contact the back plate 14 in order to form the drawing space 10s between the pressure plate 31 and the back plate 14. It is connected to. The drawing space 10s is formed over the entire axial direction D. The holding plate 31 should be large from the viewpoint of preventing the unwinding of the drawn wrap film 91f, and from the viewpoint of the ease of assembly of the wrap carton 1, it should be small within the range where the wrap roll 91r does not pop out, The area of the pressing plate 31 is preferably 0.20 to 0.95 times the area of the opening face 10h, and more preferably 0.40 to 0.75 times. In the present embodiment, the size is about 0.65. Further, in the present embodiment, the pressing plate 31 is connected to the front plate end side 19 over the entire axial direction D. By this, the pressing plate 31 is configured to be able to integrally rotate with the front plate end side 19 as the rotation axis. The pressing plate 31 is formed with a locking piece (not shown) that is locked to the side plate 15 when both ends in the axial direction D are inscribed in the side plate 15.

  The flaps 41 separate the wrap film 91 f from the front plate 12 to facilitate picking when the wrap film 91 f drawn from the wrap roll 91 r covers the front plate 12. The flap 41 is cut out and formed across the front plate 12 and the pressing plate 31 across the front plate end side 19. The flap 41 is connected to the pressing plate 31 by a flap connection line 41 c (hereinafter simply referred to as “connection line 41 c”). The flap 41 is separated from the main body 10 including the front plate 12. The flap 41 is formed so as not to be exposed from the lid 22 when the lid 20 is closed. Here, details of the flap 41 will be described with reference to FIG.

  2A is a partial front view of the flap 41 of the wrap carton 1 in the open state, FIG. 2B is a partial plan view of the flap 41 of the wrap carton 1 in the open state, and FIG. It is a fragmentary sectional view around a flap 41 of lap carton 1 of an opened lid state. As shown in FIG. 2A, the contour 42 of the flap 41 gradually spreads from the connecting line 41 c toward the tip of the flap 41. That is, the contour 42 of the flap 41 is formed so as to widen as it leaves the connection line 41 c. The flaps 41 are cut out and formed over the front plate 12 and the pressure plate 31 as described above. Therefore, the contours of the removed portions of the front plate 12 and the pressure plate 31 after the flaps 41 are cut out also become wider as they leave the connecting line 41c.

  As shown in FIG. 2B, the connection line 41c is formed in parallel with the imaginary straight line VL in the present embodiment. The virtual straight line VL is a virtual straight line of the part from which the flap 41 is pulled out, which is on the same straight line as the front plate edge 19. That is, assuming that the flap 41 is not cut out, the virtual straight line VL is the front plate end side 19. The connection line 41c is formed apart from the virtual straight line VL by a predetermined distance SB. The predetermined distance SB is preferably 0.5 mm or more, and more preferably 1 mm or more. The predetermined distance SB is preferably 10 mm or less, more preferably 5 mm or less, from the viewpoint of avoiding contact of the flap 41 with the wrap roll 91r accommodated in the main body portion 10. The predetermined distance SB may be 2 mm or 3 mm.

  As shown in FIG. 2C, the flap 41 is flat without bending from the connection line 41c to the tip. On the other hand, since the front plate 12 and the pressing plate 31 are orthogonal to each other at the front plate edge 19, the flared contour of the part from which the flap 41 is pulled is also bent at a right angle at the front plate edge 19 (virtual straight line VL) There is. For this reason, the tip end of the flap 41 is in contact with the front plate 12 and does not enter the main body portion 10. Further, the flaps 41 do not contact the front plate 12 at both sides of the contour 42 extending from both ends of the connection line 41 c toward the tip, and do not fit into the pulled out portions of the front plate 12 and the pressing plate 31. The tip of the flap 41 floats on the outside of the front plate 12. When the tip of flap 41 floats on the outside of front plate 12, wrap film 91f taken out of wrap roll 91r will surely float wrap film 91f from front plate 12 when it covers front plate 12. it can.

  FIG. 3 shows a developed view of the wrap carton 1. In the present embodiment, the main body 10, the cover 20, the pressing plate 31, and the flap 41 are those in which a coated cardboard having a thickness of about 0.45 to 0.7 mm is punched into a predetermined mold shown in FIG. It is bent and formed. For this reason, the wrap carton 1 has elasticity. In the present embodiment, for convenience of explanation, the main body 10, the lid 20, the pressure plate 31, and the flap 41 are distinguished from the viewpoint of the function, but the main body 10, the lid 20, the pressure plate 31, the flap 41 Is formed integrally by cutting out and assembling one sheet of base paper. The surface of the main body 10, the lid 20, the pressure plate 31, and the flap 41 is printed on its design so as to cause the consumer's willingness to purchase, and / or is subjected to surface treatment such as water repellent treatment, if necessary. It is done.

  As shown in FIG. 3, joint pieces 12 j are connected to both ends of the front plate 12 in the axial direction D. The joint plate 14 j is connected to both ends of the rear plate 14 in the axial direction D. The two side plates 15 are respectively connected to both ends of the bottom plate 13 in the axial direction D. The pressing plate 31, the front plate 12, the bottom plate 13, the back plate 14, the cover plate 21, and the cover plate 22 are arranged in this order, and the adjacent members are in the axial direction D except for the portion where the flap 41 is formed. It is connected throughout. Furthermore, a cut-out piece 29 is connected to the outside of the scissor cover piece 22 via a perforation 29c. The pressing plate 31, the front plate 12, the bottom plate 13 and the rear plate 14 are bent at a bending line extending in the axial direction D, and the joint piece 12j, the joint piece 14j, and the side plate 15 are each in a direction orthogonal to the axial direction D The bonding pieces 12j are overlapped and bonded to the outside of the bonding piece 14j, and the side plates 15 are bonded to the outside of the bonding pieces 14j. Thus, the pressing plate 31 is formed in the rectangular parallelepiped main body portion 10 in a state of covering the opening surface 10 h while leaving the drawing space 10 s (see FIG. 1). On the other hand, as shown in FIG. 3, side lid pieces 25 are connected to both ends of the lid plate 21 in the axial direction D. Bonding pieces 22 j are connected to both ends of the wedge cover piece 22 in the axial direction D. The back plate 14, the cover plate 21 and the lid cover piece 22 are bent at a bending line extending in the axial direction D, and the side cover piece 25 and the joint piece 22j are each bent at a bending curve extending in a direction orthogonal to the axial direction D As described above, the three-dimensional cover 20 is formed by overlapping and bonding the side cover 25 to the outside of the joint piece 22 j. In addition, when the production place of the wrap carton 1 and the production place of the wrap carton 100 are different, typically, the wrap carton 1 is in a flat folded state without being assembled in a three-dimensional manner (cuboid shape). As a wound body storage box intermediate body, the sheet is transported to the manufacturing place of the carton 100 with a wrap.

  FIG. 4 is a cross-sectional view of a flat carton 80 as a wound body storage box intermediate. The cross section shown in FIG. 4 is cut in the direction orthogonal to the axial direction D. The configuration of the flat carton 80 will be described with reference to FIG. 4 in conjunction with FIG. The flat carton 80 is bent between the presser plate 31 and the front plate 12 and viewed between the bottom plate 13 and the rear plate 14 and between the cover plate 21 and the cover 22 as seen in the developed view shown in FIG. Each is bent at. By folding in this manner, the fold plate is folded in the direction in which the holding plate 31 holds the wrap roll 91r in the main unit 10 after the lid unit 20 is opened for the first time after manufacturing the wrapped carton 100 as described later. It can be turned on. The flat carton 80 is bent at the connection line 41c. When the flat carton 80 is bent at each location, as shown in FIG. 4, the cover plate 21 is stacked on the holding plate 31, and the lid 22 and the cut piece 29 are stacked on the front plate 12. . The cover 22 and the cut piece 29 stacked on the front plate 12 have the cut pieces 29 adhered to the front plate 12 at a plurality of points, but the cover 22 is not bonded to the front plate 12. Further, the flap 41 is covered by the hook cover piece 22. In the present embodiment, the contour 42 of the flap 41 cut out over the front plate 12 and the pressure plate 31 is broadened as it is separated from the connection line 41 c, and the pressure plate with the connection line 41 c separated from the virtual straight line VL Since the flat carton 80 is formed in 31, the flap 41 does not fit into the front plate 12 and the pressure plate 31 in the flat carton 80. For this reason, in the flat carton 80, the flap 41 is sandwiched between the front plate 12 and the hook cover piece 22.

  In the flat carton 80, the side plate 15 and the side cover pieces 25 and the joint pieces 12j, 14j, 22j are not bent at bending lines perpendicular to the axial direction D, and the above-mentioned bonding has not been made yet. It has become. The flat carton 80 is obtained by peeling and flattening the side plate 15 and the side cover pieces 25 and the joint pieces 12j, 14j and 22j from the wrap carton 1 but for the improvement of manufacturing efficiency, it is not assembled once. Generally, it is manufactured to be in a folded state. In FIG. 4, the flat carton 80 is in a state in which a space is formed between the bottom plate 13 and the back plate 14 and between the front plate 12 and the pressing plate 31 for convenience of explanation. And the rear plate 14 and the front plate 12 and the pressure plate 31 are in contact with each other, and are often stored and transported.

  Next, the production of the wrapped carton 100 will be described. The flat carton 80 and the wrap roll 91r are prepared at the manufacturing place of the wrapped carton 100. And the flat carton 80 is made into the square cylinder shape which both ends opened. If it is explained in full detail about making flat container 80 into a square cylinder shape with reference to Drawing 4, it will be three-dimensionalized so that front plate 12 and back plate 14 may be perpendicular to bottom plate 13 and lid plate 21. At this time, the pressure plate 31 and the cover plate 21 may be lightly bonded so that the pressure plate 31 can follow the cover plate 21. The term “lightly attached” typically means that the flat carton 80 does not peel off when it is made into a square cylinder, and adheres to such an extent that it peels off when the wrapped carton 100 is opened for the first time as described later. As described above, the flap 41 is formed on the holding plate 31 in which the connection line 41 c is separated from the virtual straight line VL, and the front end is in contact with the front plate 12. For this reason, the flap 41 does not enter into the main body portion 10, and continues to be positioned between the front plate 12 and the lid cover piece 22. Assuming that the connection line 41 c of the flap 41 is provided on the front plate end side 19, when the flat carton 80 is formed into a square cylinder, the flap 41 passes through the cut-out space and the main body portion 10 I get stuck inside. Alternatively, assuming that the flap 41 is formed by cutting out the front plate 12 and the connecting line 41 c of the flap 41 is provided in the front plate 12, the flap 41 enters the main body 10. Although it does not occur from the front plate 12, it stays in the plane of the front plate 12. In the wrap carton 1 (flat carton 80) according to the present embodiment, such a disadvantage does not occur, and the flap 41 does not enter the main body portion 10. When the flat carton 80 is three-dimensionally shaped into a square cylinder, the wrap roll 91r is inserted from one open end. When the wrap roll 91r is inserted into the square tubular flat carton 80, the joining piece 14j, the joining piece 12j, the side plate 15, the joining piece 22j, and the side lid piece 25 at each end are sequentially bent and adhered appropriately The result is a carton 100 containing a wrap. The production of the above-described wrapped carton 100 is typically performed automatically using a cartoning machine.

  With continued reference to FIGS. 1 and 2, the operation of the wrapped carton 100 will be described. The action of the wrap carton 1 will be described as part of the action of the wrapped carton 100. In the unopened wrapped carton 100, the cut piece 29 (see FIG. 3) is connected to the tip of the tack cover piece 22 through the perforation 29c (see FIG. 3) on the tip side 22t. It is bonded to the front plate 12 at a plurality of points. When the wrap film 91 f of the carton 100 with a wrap which has been put on the consumer's hand is used for the first time, the cut piece 29 is cut at the perforations 29 c and separated from the cover piece 22 while being peeled off from the front plate 12. By unsealing the wrap carton 1 in this manner, the lid portion 20 can be turned around the rear plate end side 18 with respect to the main body portion 10.

  When opening the lid 20, the consumer usually places one palm at the center in the axial direction D of the lid plate 21, places the thumb against the lid 22 and places a finger other than the thumb against the back plate 14, The wrist is turned to turn the palm, and the lid 20 is turned around the back plate edge 18. That is, the lid 20 is opened by holding the central portion of the lid 20 in the axial direction D. When the cover 20 is opened for the first time after peeling off the cut-off piece 29 from the front plate 12, if the cover plate 21 and the holding plate 31 are lightly bonded, the adhesion is peeled and the cover 20 is opened. . At this time, the lid portion 20 is connected to the rear plate 14 with the rear plate end side 18 as the rotation axis, and the holding plate 31 is connected to the front plate 12 with the front plate end side 19 as the rotation axis. It does not go to the cover plate 21 and it peels from the cover plate 21.

  When the lid portion 20 is opened, a pressure plate 31 which partially covers the opening 10h appears. In the unwrapped carton 100, the wrap roll 91r is contained in the main body 10 when the pressing plate 31 is opened outward with the front plate end 19 as the rotation axis. In the wrap roll 91r, a withdrawal seal (not shown) is attached to the tip of the wrap film 91f, and the tip of the wrap film 91f is peeled off from the wrap roll 91r by picking and pulling out the withdrawal seal (not shown). The wrap film 91f can be easily pulled out. When the wrap film 91f is pulled out, the pressing plate 31 is pivoted around the front plate end side 19 to be closed. When the wrap film 91f is used, when the lid portion 20 is opened, the flap 41 floats on the outside of the main body portion 10. Therefore, the tip of the wrap film 91f also floats from the front plate 12 and is easy to pick. After the tip of the wrap film 91f is picked, the wrap film 91f is pulled out from the wrap roll 91r by a necessary length. At this time, although there is a case where the wrap roll 91r tries to get out of the main body portion 10 following the wrap film 91f to be pulled out, since the restraining plate 31 is provided, the wrap roll 91r pops out from the main body portion 10 Is prevented. When the wrap film 91 f is pulled out for a necessary length, it is cut by the cutting blade 23. At this time, the lid portion 20 is closed in a state in which the wrap film 91f is pulled out by a necessary length, and the wrap film 91f is sandwiched between the front plate 12 and the lid portion 22 and the figure center of the lid portion 22 is held with a thumb It is preferable to twist the wrapped carton 100 around the axis 91a so as to bite the wrap film 91f drawn at the center of 23 and to easily cut even in a state where the wrap film 91f is attached to a tableware etc. to be wrapped. Next, when the wrap film 91 f is used, when the lid portion 20 is opened, the wrap film 91 f is placed on the pressing plate 31. As described above, the pressing plate 31 can prevent the wrap film 91 f from unwinding.

  As described above, according to the wrap carton 1, the flat carton 80, and the wrapped carton 100 according to the present embodiment, the flap 41 is a pressure plate at the connection line 41c separated by a predetermined distance SB from the virtual straight line VL. Since the flat carton 80 is connected to 31, the flap 41 can be prevented from entering into the main body 10 when the flat carton 80 is three-dimensionally shaped into a square cylinder. Moreover, since the flap 41 is formed so that the outline 42 may be expanded as it leaves | separates from the connection line 41c, it can avoid that the flap 41 fits in the front plate 12. FIG.

  In the above description, the cutting blade 23 is formed in a V-shape along the tip side 22t, but may be formed in a linear shape. When the cutting blade is formed in a linear shape, generally, the wrap film 91f is cut from one end of the width of the wrap film 91f toward the other end.

  In the above description, the long material is the wrap film 91f, but it may be other than the wrap film, such as an aluminum foil or a cooking sheet.

  In the above description, the main body portion 10 is formed in a rectangular parallelepiped shape, but for example, the bottom plate 13 is curved along the outer shape of the wrap roll 91r, or the front plate 12 and the rear plate 14 are connected. The cross section orthogonal to the axial direction D may be formed in a triangle, or may be formed in a shape other than a rectangular parallelepiped shape.

  In the above description, the contour 42 of the flap 41 is formed so as to widen as it goes away from the connection line 41c, but it is formed, for example, in a rectangular (rectangular or square) shape, etc. It may be formed in a shape different from becoming divergent as it goes away from the line 41c. Even if the contour 42 of the flap 41 is formed in a shape different from a shape which becomes wider as it separates from the connection line 41c, the flap 41 is connected to the restraining plate 31 at the connection line 41c apart from the virtual straight line VL. For example, it is possible to prevent the flap 41 from entering the main body 10 when the flat carton 80 is three-dimensionally shaped into a square cylinder.

  In the above description, the wrap carton 1 is provided with the pressing plate 31. However, the pressing plate 31 may be replaced with a sub plate. The sub-plate is connected to the front plate 12 at the front plate end 19 and attached to the back side of the front plate 12. In the above-mentioned patent document 2, in order to suppress the possibility that the flap provided by cutting and raising a part of the front plate may be inserted into the cut again and the rising will be worse, in the storage container provided with the sub plate, It is disclosed to provide an offset from the cut line of the cutout. In the flap described in Patent Document 2, among the sides forming the outer edge of the flap, the side reaching the connecting side (folding line) of the front plate and the sub-plate is orthogonal to the connecting side, When the tip of the flap is offset from the cut line of the cutout, there is a possibility that the side reaching the connecting side may be inserted into the cut even if the entire flap does not fit into the cut. Below, in the wrap carton provided with a subplate, the composition which can avoid that a flap gets stuck in a cut is explained.

  FIG. 5 illustrates the periphery of the flap 41 of the wrap carton 1A provided with the sub-plate 16, and FIG. 5 (A) is a partial front view around the flap 41 of the wrap carton 1A in the open state, FIG. 5 (B). FIG. 2 is a partial cross-sectional view of a flap 41 of a wrap carton 1A in an open lid state. The wrap carton 1A includes the sub plate 16 and does not include the pressing plate 31 (see FIG. 1). The sub plate 16 is connected to the front plate 12 at the front plate end 19. The sub plate 16 is connected to the front plate 12 in the entire axial direction D. The sub plate 16 has substantially the same size as the front plate 12 but is not in contact with the bottom plate 13, and is provided on the inner side of the main body 10 </ b> A than the front plate 12. The sub plate 16 is disposed on the front plate 12 so as to be overlapped with the front plate 12 by being bent at the front plate end 19 with respect to the front plate 12 and is in contact with the front plate 12 at a surface. The sub plate 16 is bonded to the front plate 12 along the axial direction D in the vicinity of the end side on the bottom plate 13 side.

  In the wrap carton 1A, the flap 41 is connected to the sub plate 16 by the connection line 41c. The configuration of the wrap carton 1A other than the above-described point is the same as the wrap carton 1 (see FIG. 1). Therefore, the flap 41 is separated from the main body portion 10A including the front plate 12, and is formed in a size and a position not to be exposed from the cover piece 22 when the cover portion 20 is closed. Further, the contour 42 of the flap 41 is formed so as to become wider as it separates from the connection line 41 c. Therefore, the contours of the removed portions of the front plate 12 and the sub plate 16 after the flap 41 is cut out also become wider as the connecting line 41c is separated. The connection line 41c is preferably separated by 0.5 mm to 10 mm from the virtual straight line VL, more preferably by 0.7 mm to 5 mm from the virtual straight line VL, typically by 1 mm to 2 mm. The flap 41 is flat without bending from the connection line 41c to the tip. On the other hand, the flared contours of the front plate 12 and the sub plate 16 in the portion from which the flap 41 is pulled out are folded back after having once risen to the front plate edge 19 (virtual straight line VL). For this reason, the outline of the flare of the front plate 12 and the auxiliary plate 16 and the outline 42 of the flap 41 are deviated. The tip of the flap 41 overlaps the front plate 12 by twice the distance between the connection line 41 c and the virtual straight line VL. As described above, in the wrap carton 1A, the flared contours of the front plate 12 and the sub-plate 16 and the contour 42 of the flaps 41 deviate from each other, and the tips of the flaps 41 overlap the front plate 12. 41 can be reliably avoided from being fitted into the incision. In the wrap carton 1A, the flap 41 is bent at a bending line 41f on the front plate 12 side with respect to the front plate end 19 shown by a dashed dotted line in FIG. 5A without bending the connection line 41c. It is also good. In this case, the flap 41 is not the tip, but both sides of the contour extending from the bending line 41 f toward the tip overlap the front plate 12.
