  The main body 10 is a box in which one of the elongated surfaces is an opening surface 10h with respect to a rectangular parallelepiped having a size capable of accommodating an unused wrap roll 91r. The size of the main body 10 is formed as small as possible while a gap that does not prevent the accommodated unused lap roll 91r from rotating around the axis 91a is formed. In the present embodiment, the length of the main body 10 is long. The size is 310 mm, the height is 44 mm, and the depth is 44 mm. The main body 10 has a front plate 12, a bottom plate 13, and a rear plate 14 that form side surfaces of the rectangular parallelepiped in cooperation with the opening surface 10h, and two side plates 15 that form end surfaces of the rectangular parallelepiped. The bottom plate 13 faces the opening surface 10h. The front plate 12 and the rear plate 14 are orthogonal to the opening surface 10 h and the bottom plate 13. The side plates 15 are typically formed in a square shape, but may be rectangular shapes having different vertical and horizontal lengths. In the following description, the bottom plate 13 side may be described as the bottom and the opening surface 10h side as the top, with reference to the state where the bottom plate 13 is placed on a horizontal surface. A projection 15p formed by folding a small piece extending upward by about 3 mm outward is provided at the central portion of the upper end of the side plate 15. The protrusion 15p is provided at the upper end of each 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 includes a lid plate 21, a lid lid piece 22, a cutting blade 23, and a side lid piece 25. The lid plate 21 is a rectangular flat plate member having substantially the same size as the opening surface 10h, and the lid plate 21 can be formed into a rectangular parallelepiped with the main body portion 10 closed by fitting the lid plate 21 to the opening surface 10h. The lid plate 21 is substantially the same size as the opening surface 10h. The lid plate 21 is larger by the thickness of the lid lid piece 22 and the side lid piece 25, and a gap that does not hinder the opening and closing of the lid portion 20 is formed. It is meant to include cases where the degree is large. One side of the cover plate 21 parallel to the direction in which the axis 91 a of the wrap roll 91 r extends (hereinafter referred to as “axis direction D”) is connected to the rear plate end side 18 of the main body 10. In other words, the main body 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 where the rear plate 14 and the opening surface 10 h intersect. The cover plate 21 is configured to be rotatable with respect to the main body 10 with the rear plate end side 18 as a rotation axis.

  The lid piece 22 is provided so as to be orthogonal to the lid plate 21 via the bent side 21f and to extend toward the bottom plate 13 when the lid portion 20 is closed. The lid piece 22 has a height at both ends in the axial direction D (the length in the short side direction of the rectangular front plate 12) of about ½ of the length in the short side direction of the front plate 12, and 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 front end side 22t facing the bent side 21f moves from the center in the axial direction D to each end, the distance between the bent side 21f and the front end side 22t in the direction orthogonal to the axial direction D decreases. It is formed to become. With such a configuration, the tip side 22t facing the bent side 21f is formed in a V shape. When the lid portion 20 is closed, the lid cover piece 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 lid piece 22 is configured such that the length in the axial direction D 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 lid cover piece 22 is comprised so that the lap | wrap film 91f pulled out from the inside of the main-body part 10 can be pinched | interposed between the front plates 12 over the whole width. A cutting blade 23 for cutting the wrap film 91f is attached to the distal end side 22t of the lid 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 lid piece 25 is provided orthogonal to both the lid plate 21 and the lid lid 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 basic shape of the side cover piece 25 is such that the long side is the same length as the short side of the cover plate 21, and the short side is the height at the center of the lid piece 22 (from the V-shaped tip to the bent side 21f). It is formed in a rectangle having the same length as the shortest distance. The side cover piece 25 is fixed to the joining piece 22j connected to the lid cover piece 22 with an adhesive. A recess 25 d is formed on the inner side of the side lid piece 25 between the joining piece 22 j and the lid plate 21.

  The holding plate 31 is a member for preventing the wrap film 91f drawn out from the wrap roll 91r accommodated in the main body 10 from being unwound. The rewinding of the wrap film 91f is a phenomenon in which the tip of the wrap film 91f once drawn from the wrap roll 91r adheres to the wrap roll 91r. Further, the holding plate 31 also contributes to preventing the wrap roll 91r from jumping out from the main body 10. The holding plate 31 is a flat plate-like member that partially covers the opening surface 10 h leaving at least a space for the drawing space 10 s and the adhesive piece 41 for pulling the wrap film 91 f from the wrap roll 91 r accommodated in the main body 10. is there. The lead-out space 10s is preferably of a size that does not hinder the withdrawal of the wrap film 91f and is thinner than the diameter of the core around which the wrap film 91f is wound. If comprised in this way, jumping out from the main-body part 10 of the wrap roll 91r (or winding core) can be prevented until the time of using the wrap film 91f ending. In addition, the wrap roll 91r accommodated in the main-body part 10 may have no core. The holding plate 31 is connected to the front plate edge 19 of the main body 10. In other words, the main body 10 and the holding plate 31 are connected via the front plate edge 19. The front plate end side 19 is an end side of the front plate 12 where the front plate 12 and the opening surface 10 h intersect, and is a side parallel to the axial direction D.

  In the present embodiment, the holding plate 31 is formed in a size that does not contact the rear plate 14 in order to form the drawer space 10 s between the holding plate 31 and the rear plate 14. It is connected to. The lead-out space 10s is formed over the entire axial direction D. In the present embodiment, a hollow portion 31 d is further formed in the holding plate 31. The hollow portion 31d is a portion where the opening surface 10h is not covered by the holding plate 31, and is a space in which the adhesive piece 41 enters when the lid portion 20 is closed. The hollow portion 31 d is formed in the center of the holding plate 31 in the axial direction D. Further, the hollow portion 31 d does not reach the front plate end side 19. For this reason, the holding plate 31 is connected to the front plate edge 19 over the entire axial direction D. Thus, the holding plate 31 is configured to be able to rotate integrally with the front plate edge 19 as the rotation axis. The holding plate 31 is formed with a locking piece (not shown) that locks the side plate 15 when both ends in the axial direction D are inscribed in the side plate 15. The hollow portion 31d is formed in a trapezoidal shape by the portion closest to the front plate edge 19 extending in parallel to the front plate edge 19 and extending from both ends of the parallel line toward the rear plate edge 18. ing.

  The adhesive piece 41 is adhered to the lid plate 21 in FIG. The adhesive piece 41 has the same shape (that is, congruence) as the hollow portion 31d. The adhesive piece 41 is adhered to the lid plate 21 at a position where the adhesive piece 41 is fitted to the hollow portion 31d when the lid portion 20 is closed. 1, the adhesive piece 41 is separated from the holding plate 31 and remains on the lid portion 20 because the lid portion 20 is opened. However, before the wrapping carton 100 is opened (the lid portion 20 is opened for the first time). (Before opening) is the one that was coupled to the holding plate 31.

  FIG. 2 shows a state before the holding plate 31 and the adhesive piece 41 are separated. In the plan view shown in FIG. 2, the upper side of the paper corresponds to the rear plate edge 18 side, and the lower side of the paper corresponds to the front plate edge 19 side. The holding plate 31 and the adhesive piece 41 are coupled along the cutting line 35. The cutting line 35 is a line where the holding plate 31 and the adhesive piece 41 are separated when the wrapped carton 100 (see FIG. 1) is opened for the first time. In the present embodiment, the cutting line 35 includes a cutting part 35g extending parallel to the axial direction D, and a pair of perforations 35p extending linearly from both ends of the cutting part 35g to the side on the rear plate end side 18 side. It is configured. A portion surrounded by a cutting line 35 corresponding to three sides and a side on the rear plate end side 18 between the pair of perforations 35p is a trapezoidal adhesive piece 41. The adhesive piece 41 is formed symmetrically about a virtual straight line (not shown) that bisects the opening surface 10h in the axial direction D. In this embodiment, the adhesive piece 41 has a side on the rear plate end side 18 side that is approximately ½ the length of the rear plate end side 18 and a side on the front plate end side 19 side that is the rear plate end. Each of the sides 18 is formed to have a length that is approximately 1/3 of the length of the side 18.

  The cutting part 35g constituting the cutting line 35 is formed by cutting the holding plate 31 and the adhesive piece 41 and forming a cutting line or slit-like gap. The cut line is a line cut. The slit-shaped gap is typically about 0.5 mm to 1.0 mm in width, but may exceed 1.0 mm or less than 0.5 mm. The perforation 35p constituting the cutting line 35 is formed such that the gap C between the broken-line holes for forming the perforation 35p is wider on the front plate 12 side than on the rear plate 14 side. In the present embodiment, when the perforation 35p is traced from the front plate 12 side to the rear plate 14, the hole interval C is formed so as to be gradually reduced. By being configured in this way, the holding plate 31 and the adhesive piece 41 are joined weaker on the front plate 12 side than on the rear plate 14 side. Here, the strength of the bond means the strength of the force required for separation. The portion of the perforation 35p that is sandwiched between adjacent holes and that joins the holding plate 31 and the adhesive piece 41 is typically the same length anywhere, but the front plate 12 side is the same. Different lengths are possible as long as they are weaker than the rear plate 14 side. In addition, the holding plate 31 and the adhesive piece 41 are coupled so as to be separable with a predetermined force as a whole. The predetermined force is typically a force that an ordinary person can open without difficulty.

  FIG. 3 shows a development view of the wrap carton 1. In this embodiment, the main body 10, the lid 20, the holding plate 31, and the adhesive piece 41 are obtained by punching coated cardboard having a thickness of about 0.45 to 0.7 mm into a predetermined mold shown in FIG. 3. Is formed by bending. For this reason, the wrap carton 1 has elasticity. In the present embodiment, for convenience of explanation, the main body portion 10, the lid portion 20, the holding plate 31, and the adhesive piece 41 are distinguished from the viewpoint of function. The piece 41 is integrally formed by cutting and assembling one base paper. The surface of the main body 10, the lid 20, and the holding plate 31 is printed with a design that provokes consumers' willingness to purchase and / or is subjected to a surface treatment such as a water repellent treatment as necessary. .

  As shown in FIG. 3, the front plate 12 has joined pieces 12 j connected to both ends in the axial direction D. Joining pieces 14 j are connected to the rear plate 14 at both ends in the axial direction D. The two side plates 15 are connected to both ends of the bottom plate 13 in the axial direction D, respectively. The holding plate 31, the front plate 12, the bottom plate 13, the rear plate 14, the cover plate 21, and the lid cover piece 22 to which the adhesive piece 41 is coupled are arranged in this order, and adjacent members are connected to each other in the entire axial direction D.

The holding plate 31, the front plate 12, the bottom plate 13, and the rear plate 14 to which the adhesive piece 41 is coupled are bent along a folding line extending in the axial direction D, and the bonding piece 12 j, the bonding piece 14 j, and the side plate 15 are respectively It is bent by a fold line extending in a direction orthogonal to the axial direction D, the joining piece 12j is overlapped and bonded to the outside of the joining piece 14j, and the side plate 15 is further overlapped and bonded to these outsides, thereby suppressing it. The plate 31 and the adhesive piece 41 are formed in the rectangular parallelepiped main body 10 in a state of covering the opening surface 10h leaving the drawer space 10s (see FIG. 1). On the other hand, as shown in FIG. 3, side cover pieces 25 are connected to the cover plate 21 at both ends in the axial direction D. Joining pieces 22 j are connected to the lid piece 22 at both ends in the axial direction D. The rear plate 14, the lid plate 21, and the lid piece 22 are bent along a folding line extending in the axial direction D, and the side lid piece 25 and the joining piece 22 j are each bent along a folding line extending in a direction orthogonal to the axial direction D. As described above, the three-dimensional lid portion 20 is formed by overlapping the side lid pieces 25 on the outside of the joining pieces 22j and bonding them. When the manufacturing location of the wrap carton 1 and the manufacturing location of the wrapping carton 100 are different, typically, the wrap carton 1 is not assembled in a three-dimensional shape (cuboid shape) but is folded flat. As a wound body containing box intermediate body, it is conveyed to the manufacturing place of the carton 100 with wraps.

  FIG. 4 is a cross-sectional view of a flat carton 80 as an intermediate body of a wound body storage box. The cross section shown in FIG. 4 is cut in a direction perpendicular to the axial direction D. The configuration of the flat carton 80 will be described with reference to FIG. 4 together with FIG. The flat carton 80 is bent between the holding plate 31 and the front plate 12 to which the adhesive pieces 41 are bonded, as well as between the bottom plate 13 and the rear plate 14, and the lid plate 21 as seen in the development shown in FIG. 3. And the lid lid piece 22 are bent respectively. By being bent in this way, after the lid portion 20 is opened for the first time after the wrapping carton 100 is manufactured as described later, the folds are folded in a direction in which the holding plate 31 holds the lap roll 91r in the main body portion 10. You can turn it on. When the flat carton 80 is bent at each location, as shown in FIG. 4, the cover plate 21 is overlaid on the holding plate 31 to which the adhesive piece 41 is bonded, and the lid cover piece 22 is placed on the front plate 12. And the cut piece 29 is piled up. In this state, an adhesive is applied to the adhesive piece 41, and the adhesive piece 41 is adhered to the lid plate 21. The holding plate 31 coupled to the adhesive piece 41 is close to the lid plate 21 and may be in contact with the lid plate 21, but is not bonded to the lid plate 21. The lid piece 22 and the cut piece 29 stacked on the front plate 12 are bonded to the front plate 12 at a plurality of points, but the lid cover piece 22 is not bonded to the front plate 12. In the flat carton 80, the side plate 15, the side lid piece 25, and the joining pieces 12j, 14j, and 22j are not folded at the folding line orthogonal to the axial direction D, and the joining as described above is not yet performed. It has become. The flat carton 80 is formed by peeling the side plate 15, the side cover piece 25, and the joining pieces 12 j, 14 j, and 22 j from the wrap carton 1, but it is not assembled once to improve manufacturing efficiency. Generally, it is manufactured to be in a folded state. In FIG. 4, the flat carton 80 is in a state where spaces are formed between the bottom plate 13 and the rear plate 14 and between the front plate 12 and the holding plate 31 for convenience of explanation. In many cases, the flat plate is flattened so as to be in contact with each other between the front plate 12 and the rear plate 14 and between the front plate 12 and the holding plate 31.

  Next, manufacture of the wrapping carton 100 will be described. A flat carton 80 and a wrap roll 91r are prepared at the manufacturing location of the wrapping carton 100. And the flat carton 80 is made into the square cylinder shape which both ends opened, and the wrap roll 91r is inserted from one end surface. If the flat carton 80 is formed into a rectangular tube shape in detail, referring to FIG. 4, the flat carton 80 is three-dimensionalized so that the front plate 12 and the rear plate 14 are orthogonal to the bottom plate 13 and the cover plate 21. At this time, the holding plate 31 bonded to the adhesive piece 41 goes along the lid plate 21 together with the adhesive piece 41 bonded to the lid plate 21. Therefore, the pressing plate 31 does not enter a state of blocking the three-dimensional rectangular cylindrical internal space. If the adhesive piece 41 is not bonded to the holding plate 31 and the holding plate 31 is not bonded to the lid plate 21, the holding plate 31 bent at an acute angle with respect to the front plate 12 is attached to the lid plate 21. When it is three-dimensionally orthogonal to the front plate 12, the lid plate 21 is not moved, and the three-dimensional rectangular tube-like internal space is shut off, which hinders the insertion of the wrap roll 91 r. In the flat carton 80 according to the present embodiment, since the holding plate 31 coupled to the adhesive piece 41 goes along the cover plate 21 when three-dimensionalized, it is avoided that the insertion of the wrap roll 91r from one end is hindered. can do. After the wrap roll 91r is inserted into the flat carton 80 in the shape of a square cylinder, the joining pieces 14j, joining pieces 12j, side plates 15, joining pieces 22j, and side lid pieces 25 at both ends are sequentially bent and bonded appropriately. Thus, the carton 100 with wrap is obtained. In addition, the manufacture of the wrapping carton 100 described above is typically performed automatically using a carting machine.

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

  When the consumer opens the lid portion 20, he usually places one palm in the center of the axial direction D of the lid plate 21, puts his thumb against the lid lid piece 22, and puts a finger other than the thumb against the rear plate 14, The wrist is turned so as to return the palm, and the lid 20 is rotated around the rear plate edge 18. That is, the lid portion 20 is opened with the central portion in the axial direction D of the lid portion 20. On the other hand, the unopened wrapped carton 100 includes a holding plate 31 that is connected to the front plate 12 and is not bonded to the cover plate 21 inside the cover portion 20, and an adhesive piece 41 that is bonded to the cover plate 21. Are in a combined state. When the lid 20 is opened for the first time after the cut piece 29 is peeled off from the front plate 12, the holding plate 31 is held by the front plate 12, and the adhesive piece 41 is not separated from the lid plate 21. Is separated by a cutting line 35. Since the force point when opening the lid portion 20 is the thumb portion applied to the lid piece 22, the moment acting on the cutting line 35 increases as the distance from the force point increases. In the wrap carton 1 according to the present embodiment, since the connection between the holding plate 31 and the adhesive piece 41 at the cutting line 35 is weaker on the front plate 12 side than on the rear plate 14 side, a relatively large moment is generated. It is easy to open the lid 20 when cutting near the smaller cutting portion 35g. Further, even if the coupling is relatively strong in the vicinity of the rear plate edge 18, the moment is relatively large, so there is no problem in opening the lid 20. Since the holding plate 31 and the adhesive piece 41 are relatively strongly coupled in the vicinity of the rear plate edge 18, the holding plate 31 is bonded at the stage where the flat carton 80 (see FIG. 4) is three-dimensionalized into a square cylinder. The risk of separation from the piece 41 can be reduced.

  When the lid portion 20 is opened, a holding plate 31 that partially covers the opening surface 10h appears. Since the holding plate 31 is not bonded to the lid plate 21, there is no adhesion mark on the surface, and the appearance is clean. If you look at the opened lid 20, the adhesive piece 41 is attached to the back surface of the lid 21. Since the adhesive piece 41 adheres to the cover plate 21, there is an advantage that the strength of the cover plate 21 is improved. When the unwrapped carton 100 with the wrap is opened with the front plate edge 19 as the rotation axis and the plate 31 is opened to the outside, a wrap roll 91r is contained in the main body 10. The wrap roll 91r has a drawer seal (not shown) attached to the tip of the wrap film 91f, and the tip of the wrap film 91f is peeled from the wrap roll 91r by pulling out the drawer seal (not shown). The wrap film 91f can be pulled out easily. When the wrap film 91f is pulled out, the holding plate 31 is turned around the front plate edge 19 and closed. In addition, when the wrap film 91f can be pulled out from the hollow portion 31d after the adhesive piece 41 is separated by pulling out a draw seal (not shown), the holding plate 31 may be kept closed. When using the wrap film 91f, the wrap film 91f is pulled out from the wrap roll 91r by a necessary length. At this time, the wrap roll 91r may be pulled out of the main body 10 by being pulled by the drawn wrap film 91f. However, since the holding plate 31 is provided, the wrap roll 91r jumps out from the main body 10. Is prevented. When the wrap film 91f is pulled out by a necessary length, it is cut by the cutting blade 23. At this time, the lid portion 20 is closed with the wrap film 91f pulled out by a necessary length, the wrap film 91f is sandwiched between the front plate 12 and the lid cover piece 22, the centroid of the lid cover piece 22 is pressed with the thumb, and the cutting blade When the wrapping carton 100 is twisted around the axis 91a so that the center of the wrap film 91f is drawn into the drawn wrap film 91f, it is easy to cut even when the wrap film 91f is attached to the tableware to be wrapped. Next, when the wrap film 91f is used, when the lid 20 is opened, the tip of the wrap film 91f is on the restraining plate 31. Thus, the rewinding of the wrap film 91f can be prevented by the holding plate 31.

  As described above, according to the wrap carton 1, the flat carton 80, and the carton 100 with a wrap according to the present embodiment, the wrap roll is applied to the three-dimensional flat carton 80 without impairing the function of the holding plate 31. 91r can be smoothly inserted, the lid 20 can be opened for the first time smoothly, and an adhesive peeling mark can be left on the holding plate 31 after opening.

  In the above description, the cutting line 35 parallel to the front plate edge 19 is the cutting part 35g, but it may be a cutting line 35 other than the cutting part 35g, such as a perforation.

  In the above description, the adhesive piece 41 has a trapezoidal shape extending from the front plate end side 19 side toward the rear plate end side 18, but the shape spreading from the front plate end side 19 side toward the rear plate end side 18. Other shapes may be used, and shapes other than trapezoids may be used. However, if the shape expands from the front plate edge 19 toward the rear plate edge 18, the moment acting on the vicinity of the rear plate edge 18 may be increased when the lid 20 is opened for the first time in a normal manner. In addition, the area of the adhesive piece 41 can be increased. By increasing the area of the adhesive piece 41, it is possible to reduce the risk that the restraining plate 31 will be separated from the adhesive piece 41 in the stage where the flat carton 80 is three-dimensionalized into a square cylinder, and the lid portion 20 is used for the first time. The strength of the lid plate 21 when the adhesive piece 41 is attached to the lid plate 21 can be improved. Further, in the above description, the adhesive piece 41 is provided at one place in the center of the axial direction D of the holding plate 31, but may be provided at a plurality of places with a gap in the axial direction D. In the above description, the adhesive piece 41 has the same size and shape as the hollow portion 31d, but may have a different size and / or a different shape from the hollow portion 31d.

  In the above description, the cutting blade 23 is formed in a V shape along the tip side 22t. However, it may be formed in a straight line. When the cutting blade is formed in a straight line, the wrap film 91f is generally cut from one end of the width of the wrap film 91f to the other end.

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