  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar members are denoted by the same or similar reference numerals, and redundant description is omitted.

  First, referring to FIG. 1, a wrap carton 1 as a wound body storage box and a wrapped body containing a wrap roll 91r as a wound body in the wrap carton 1 according to the embodiment of the present invention. A carton 100 with a wrap as a box will be described. 1A is a perspective view of a wrapping carton 100, and FIG. 1B is a partial side sectional view of the wrapping carton 1. FIG. FIG. 1A shows an open state. The wrap roll 91r is formed by rolling a wrap film 91f as a thin thin film around a shaft 91a around a cylindrical core. In the following description, when the appearance shapes of the wrap roll 91r and the wrap film 91f are not distinguished, they are collectively referred to as “wrap 91”. In this embodiment, the wrap film 91f is formed to have a thickness of 5 to 20 μm using polyvinylidene chloride as a raw material. The wrap carton 1 includes a main body portion 10 that accommodates the wrap roll 91r and a lid portion 20 that is connected to the main body portion 10.

  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 width is 44 mm, It has a size of 44 mm in height and 310 mm in length. The length of the main body 10 here is the length in the direction in which the axis 91a of the wrap roll 91r extends (hereinafter referred to as “axis direction D”). 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. Further, the main body 10 has a sub plate 16 (see FIG. 1B) that is continuous with the front plate 12 at the front plate end side 19. The front plate edge 19 is an edge of the front plate 12 where the front plate 12 and the opening surface 10h intersect, and also serves as a boundary between the front plate 12 and the sub plate 16 in the present embodiment. Further, in the present embodiment, the parallel direction, which is the direction in which the front plate edge 19 extends, coincides with the axial direction D. The sub-plate 16 is substantially the same size as the front plate 12 but is not in contact with the bottom plate 13 and is provided inside the main body 10 with respect to the front plate 12. The sub-plate 16 is bonded to the front plate 12 along the axial direction D at the end side on the bottom plate 13 side.

  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 extending in the axial 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. When the lid portion 20 is closed, a protrusion 15p provided on the upper end of the side plate 15 is fitted into the recess 25d. When the lid portion 20 configured as described above is closed, the lid portion 20 covers the opening 10h of the main body portion 10, and the lid lid piece 22 covers the upper portion of the front plate 12.

  In the present embodiment, the main body 10 and the lid 20 are formed by processing coated cardboard having a thickness of about 0.45 to 0.7 mm. For this reason, the wrap carton 1 has elasticity. In the present embodiment, for convenience of explanation, the main body 10 and the lid 20 are distinguished from the viewpoint of function. However, the main body 10 and the lid 20 are integrally formed by cutting out a single base paper. Is formed. The surface of the main body 10 and the lid 20 is subjected to a surface treatment such as a water repellent process after a design that causes consumers to purchase is printed. In the wrap carton 1, a flap 12 f that is separated from the sub-plate 16 and floats outside the main body 10 is formed in the upper portion of the front plate 12 by cutting the surface of the front plate 12. That is, the front plate 12 includes the flap 12f.

  Here, the details of the flap 12f will be described with reference to FIG. 2 together with FIG. FIG. 2 is a front view of the main body 10 of the lap carton 1. In the present embodiment, the flap 12f is located outside the central region C along the front plate edge 19 so as to sandwich the central region C located in the center in the longitudinal direction of the front plate 12 (the same direction as the axial direction D). Is provided. The “central region C” is defined as follows. A portion of the front plate 12 that is covered with the lid piece 22 when the lid 20 is closed is referred to as a “covering region W”. In FIG. 2, a portion surrounded by a virtual boundary line 12 b indicated by a two-dot chain line, a front plate end side 19, and both side plates 15 is a covered region W. The covering region W is divided into three in the longitudinal direction (axial direction D) of the front plate 12, and the middle region is defined as a central region C and both sides thereof as “main regions M”. In other words, two main regions M are formed so as to sandwich the central region C therebetween. The width of the central region C (distance in the axial direction D) is such that the centroid of the lid cover piece 22 (the portion of the lid cover piece 22 near the apex of the V-shape of the tip side 22t) with the lid 20 closed is the flap 12f. Assuming that is not formed, it is an arbitrary value within a range of ± 20% with reference to the distance in the range where the lid cover piece 22 contacts when pressed toward the front plate 12. For example, when the centroid of the lid cover piece 22 is pushed toward the front plate 12 with the lid portion 20 closed, if the range where the lid cover piece 22 contacts the front plate 12 is 30 mm, the width of the central region C is It can be arbitrarily determined between 24 mm and 36 mm. At this time, the elastic wrap carton 1 can change the range in which the lid cover piece 22 and the front plate 12 are in contact with each other depending on the magnitude of the force pushing the lid cover piece 22 toward the front plate 12, but defines the central region C. In doing so, when the centroid of the lid piece 22 is pushed toward the front plate 12 with the unused wrap roll 91r accommodated in the main body 10, the front plate 12 is in the wrap roll 91r in the main body 10. The distance in the axial direction D in the range where the lid cover piece 22 and the front plate 12 are in contact with each other when no longer moved to the rear plate 14 side is used as a reference for defining the width of the central region C. Typically, this reference itself may be the width of the central region C. In the present embodiment, the width of the central region C is defined as 32 mm and is approximately 10 to 11% of the width of the front plate 12 (distance in the axial direction D), but the width of the central region C is 20 mm to 70 mm, Preferably, it may be determined in the range of 30 mm to 50 mm, or 6% to 25%, preferably 10% to 16% of the width of the front plate 12 (distance in the axial direction D).

  For the sake of convenience of explanation, two flaps 12f provided with the central region C sandwiched therebetween are shown in the front view (see FIG. 2). The left flap 12f of the central region C is the left flap 12fA and the right flap 12f of the central region C is. Is the right flap 12fB. The left flap 12fA and the right flap 12fB correspond to a first flap and a second flap, respectively. Hereinafter, when a configuration common to the left flap 12fA and the right flap 12fB is described, it is simply referred to as “flap 12f”. Further, the side plate 15 near the left flap 12fA may be called the left side plate 15A (first side plate), and the side plate 15 near the right flap 12fB may be called the right side plate 15B (second side plate). The plate 15 is a generic name for these. The left flap 12fA is formed in a size included in the left main region M. The right flap 12fB is formed in a size included in the right main region M.

  The left flap 12fA has a cut line 12cA formed in the surface of the front plate 12 and a front plate end side 19 as an outline. The cut line 12cA is a line for cutting a part of the front plate 12. The cut line 12cA is closer to the left side plate 15A than the central region C, and passes from the point 12cAN on the front plate edge 19 close to the central region C through the front plate 12 and close to the left side plate 15A. It is formed by cutting the in-plane of the front plate 12 so as to reach the point 12cAS on the plate edge 19. The point 12cAN is located in the vicinity of the central region C to such an extent that the wrap film 91f does not slip so that the cut edge of the wrap film 91f is unacceptable when the drawn wrap film 91f is cut. The point 12cAS is located slightly closer to the center region C than the left end of the drawn wrap film 91f, but may be located between the left end of the wrap film 91f and the left side plate 15A. The left end of the left flap 12fA (the position of the point 12cAS) is slightly closer to the center region C than the left end of the wrap film 91f is to the left of the wrap film 91f so that the wrap film 91f can be cut without sagging when the wrap film 91f is cut. The left end of the left flap 12fA does not reach the left end of the wrap film 91f as long as it can be sandwiched between the flap 12fA and the lid cover piece 22. This state, the state in which the left end of the left flap 12fA coincides with the left end of the wrap film 91f, and the state in which the left end of the left flap 12fA is outside the left end of the wrap film 91f are collectively referred to as the left flap 12fA. It is assumed that it extends substantially to the left end. When the left end of the left flap 12fA is formed closer to the center region C than the left end of the wrap film 91f, a decrease in strength of the main body 10 around the end of the front plate 12 in the axial direction D can be suppressed. In the present embodiment, the left end of the left flap 12fA is formed closer to the central region C by 15 mm than the left end of the front plate 12 in the axial direction D, but may be formed closer to the central region C by 10 mm or 5 mm. . The maximum length of the left flap 12fA in the orthogonal direction R (the direction orthogonal to the front plate end side 19) is about ½ of the length of the front plate 12 in the orthogonal direction R. In the present embodiment, the lower side of the left flap 12fA is once again approached to the front plate end side 19 once again when it is traced from the central region C side in the axial direction D to the left side plate 15A side. It is formed in a smooth curve that separates from the end side 19. In other words, the center portion of the left flap 12fA is recessed above both ends. The left flap 12fA is formed in a size that is covered with the lid lid piece 22 and does not appear on the outer surface when the lid portion 20 is closed.

  Since both ends 12cAN and 12cAS of the cut line 12cA constituting the outline of the left flap 12fA reach the front plate end side 19, the floating of the left flap 12fA from the sub-plate 16 can be kept good. In addition, when the left flap 12fA is excessively lifted from the surface of the front plate 12 on the outer side, the floating state can be adjusted by slightly separating both ends of the cutting line 12cA from the front plate end side 19. As the distance between the end of the cut line 12cA and the front plate edge 19 becomes longer, the floating amount of the left flap 12fA becomes smaller. For example, the floating amount becomes smaller when the distance is 5 mm than when the distance is 3 mm. The left flap 12fA is configured so as not to drop off from the main body 10 even if it is cut along the cutting line 12cA by being connected to the sub-plate 16 at the front plate edge 19. Further, the left flap 12fA is configured to be able to rotate about the front plate end side 19 as a rotation axis by being connected to the sub plate 16 at the front plate end side 19.

  On the surface of the left flap 12fA, a stopper 50 as a locking means is formed substantially along the front plate edge 19 at a predetermined position. In this embodiment, the stopper 50 is formed by applying UV varnish. The UV varnish that forms the stopper 50 adheres to the wrap film 91f, but does not adhere paper or dust. The wrap film 91f attached to the stopper 50 adheres strongly in the direction parallel to the attachment surface (shear direction), but relatively weakly in the direction perpendicular to the attachment surface (direction away from the attachment surface). That is, the stopper 50 prevents the wrap film 91f from moving in the pull-out direction P when the wrap film 91f is pulled along the front plate 12 in the pull-out direction P, which is the direction in which the wrap film 91f is pulled out from the main body 10. When the wrap film 91f is attached and pulled so that the wrap film 91f is turned away from the attachment surface, the wrap film 91f is peeled off. The stopper 50 “substantially formed along the front plate edge 19” is a normal mode when the wrap film 91 f is pulled out, but can contact the front plate edge 19, but the front plate 12. Is a state in which the stopper 50 is formed near the front plate edge 19 within a range where it does not come into contact with the drawn wrap film 91f when being drawn in a floating state.

  The viewpoint where the stopper 50 is formed will be described by dividing the viewpoint into the axial direction D and the orthogonal direction R. In the present embodiment, in the axial direction D, the stopper 50 is formed over substantially the entire length in the axial direction D of the left flap 12fA. Here, “substantially formed over the entire length in the axial direction D of the left flap 12fA” is not intended to require that it is formed strictly continuously, but is appropriate when cutting the wrap film 91f. As long as the wrap film 91f can be prevented from moving to such an extent that the wrap film 91f is prevented from being moved to such an extent that it is prevented from being cut, there are portions that are not formed intermittently or are formed at both ends. It means that there are no parts.

  The height of the stopper 50 (distance in the orthogonal direction R) is a position that once approaches the front plate edge 19 when the cutting line 12cA is traced from the central region C side to the left side plate 15A side (the axial direction of the left flap 12fA). The position changes substantially along the cut line 12cA up to the position recessed above the central portion in D). For example, the basic shape of the contour on the lower side of the stopper 50 changes so as to be inside about 4 mm from the cut line 12cA until it reaches a position slightly closer to the front plate edge 19 once. The maximum height of the stopper 50 up to a position slightly approaching the front plate edge 19 is about 15 mm. The height of the stopper 50 is about 9 mm on the left side plate 15 </ b> A side from a position that slightly approaches the front plate end side 19, and is almost the same height. In addition, the space between the upper end (upper contour) of the stopper 50 and the front plate edge 19 is about 2 mm.

  Further, a gap 51g where the stopper 50 is not formed is formed in the stopper 50 on the left flap 12fA. The gap 51g is formed in a plurality of vertically long gaps extending in the orthogonal direction R with an interval in the axial direction D. In the present embodiment, each gap 51g divides the stopper 50 formed along the front plate edge 19 and penetrates in the vertical direction. That is, in this embodiment, each stopper 50 and each gap 51g are formed continuously in the orthogonal direction R. Moreover, in this Embodiment, the part in which the stopper 50 remained in the axial direction D and the part of the clearance gap 51g are alternately formed with the same dimension. The stopper 50 and the gap 51g in this manner are also formed on the surface of the front plate 12 between the left flap 12fA and the left side plate 15A in the covered region W. Furthermore, before supplementing the description of the relationship between the stopper 50 and the gap 51g below, the range of the front plate 12 newly defined will be described.

  With reference to FIG. 3, the range of the front plate 12 divided for convenience of description will be described. First, the belt-like region E will be described with reference to FIG. The belt-like region E is a region included in the covered region W and extends to the entire front plate 12 in the axial direction D (corresponding to the parallel direction). The belt-like region E extends in the axial direction D with a width of 5 mm to 10 mm in the orthogonal direction R. Further, the belt-like region E is separated from the front plate edge 19 in the orthogonal direction R by 0.5 mm to 10 mm. As described above, the front plate end side 19 forms a boundary between the front plate 12 and the sub-plate 16 and has a thickness corresponding to the folded portion. The front plate edge 19 when the separation of the front plate 12 is defined is based on the boundary of the front plate 12 on the opening surface 10 h side when the front plate 12 is viewed perpendicularly to the surface of the front plate 12. In the present embodiment, the belt-like region E is 2 mm away from the front plate edge 19 in the orthogonal direction R and extends in the axial direction D with a width of 9 mm in the orthogonal direction R.

  Next, the contact range F and the outer contact range Fs will be described with reference to FIG. The contact range F is obtained when the wrap film 91f is pulled out from the wrap roll 91r accommodated in the main body 10 and the wrap film 91f covers the entire covered region W in the orthogonal direction R (typical for the axial direction D). In this case, both ends of the covering region W are not covered with the wrap film 91f), and the range of the front plate 12 with which the wrap film 91f contacts in the covering region W in a state where the lid portion 20 is open. In the present embodiment, since the front plate 12 has the flap 12f that floats outside the main body 10, the entire surface of the flap 12f becomes the contact range F. If the flap 12f is not formed on the front plate 12, it is assumed that the wrap film 91f and the front plate 12 are in contact with each other over the entire area where the drawn wrap film 91f covers the front plate 12, and the axial direction D The entire covered area W of the width of the wrap film 91 f becomes the contact range F. Then, in the contact range F, 100 mm is moved toward the side plate 15 from the center of the covering region W in the axial direction D (the portion on the virtual straight line 12v in FIG. The outer side (side plate 15 side) from the point 12s that has been made is defined as the outer contact range Fs, and the inner side as the inner contact range Fn. That is, the contact range F can be divided into an outer contact range Fs and an inner contact range Fn. And the part which the strip | belt-shaped area | region E shown to FIG. 3 (A) and the outer side contact range Fs shown to FIG. 3 (B) overlap shall be prescribed | regulated as the overlapping part EFs shown to FIG. 3 (C).

  Returning to FIG. 2 again, with reference to FIG. 3 as necessary, the configurations of the stopper 50 and the gap 51g in the overlapping portion EFs will be supplementarily described. As described above, in the state where the stoppers 50 and the gaps 51g are alternately formed on the left flap 12fA, the total area of the stoppers 50 formed in the overlapping portion EFs is the outer contact range Fs (see FIG. 3B). ) Of 30% to 60%, preferably 40% to 50%. Further, a stopper 50 is formed on the bottom plate 13 side (opposite side of the front plate edge 19) outside the overlapping portion EFs (see FIG. 3C) in the outer contact range Fs (see FIG. 3B). It has not been. In the present embodiment, as shown in FIG. 2, a stopper is also provided on the front plate edge 19 side outside the overlapping portion EFs (see FIG. 3C) in the outer contact range Fs (see FIG. 3B). 50 is not formed. In addition, in the belt-like region E (overlapping portion EFs) in the outer contact range Fs, the stopper 50 and the gap 51g have a width in the axial direction D (corresponding to the parallel direction) in the range of 1 mm to 7 mm in the axial direction D. It is formed alternately. In the present embodiment, the width in the axial direction D has the same dimension (for example, 3 mm) and is alternately formed in the axial direction D. However, the width of the stopper 50 and the gap 51g in the axial direction D can be selected as appropriate. By forming the stopper 50 in this way, the wrap film 91f is not too closely adhered to the stopper 50 in the outer contact range Fs, and the wrap film 91f is prevented from being damaged such as a vertical tear or an oblique cut. be able to.

  The description of the flap 12f will be continued with reference to FIGS. The right flap 12fB is formed in line symmetry with the left flap 12fA with a virtual straight line 12v that bisects the front plate 12 to the left and right as the symmetry axis. The cut line 12cB, the point 12cBN, and the point 12cBS of the right flap 12fB correspond to the cut line 12cA, the point 12cAN, and the point 12cAS of the left flap 12fA, respectively. Also on the right flap 12fB, the stopper 50 is formed in line symmetry with the stopper 50 formed on the left flap 12fA with the virtual straight line 12v as an axis. The stopper 50 is also formed in the central region C substantially along the front plate edge 19.

  In the stopper 50 formed in the central region C, as in the main region M, the portions where the stopper 50 remains and the portions of the gap 51g are alternately formed with the same dimension (for example, 3 mm). The stopper 50 formed in the central region C also has a space of about 2 mm between its upper end (upper contour) and the front plate edge 19. The height (length in the orthogonal direction R) of the stopper 50 formed in the central region C is about 4 mm at the central portion in the axial direction D and about 5 mm at both end portions (portions adjacent to the main region M). . As described above, the height of the stopper 50 in the central region C is shorter than the maximum height of the stopper 50 in the main region M.

  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. In the unopened wrapped carton 100, a cut piece (not shown) is connected to the tip of the lid piece 22 via a perforation (not shown) on the tip side 22t. The plate 12 is bonded at a plurality of points. When the wrap film 91f is used for the first time, the cut piece (not shown) is cut off at the perforation (not shown) while being peeled off from the front plate 12, and separated from the lid 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.

  The unwrapped carton 100 with a wrap has a wrap roll 91 r 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 used, the wrap film 91f is pulled out from the wrap roll 91r by a necessary length and 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.

  When the wrap film 91f is pulled out and cut, normally, the center portion in the width direction at the tip of the wrap film 91f is picked and pulled out, and the lid portion 20 is closed and cut without changing. While the wrap film 91f is being cut along the cutting blade 23 from the center portion in the width direction of the wrap film 91f toward the both ends, the wrap film 91f near the center portion in the width direction immediately after being cut is the wrap film 91f. Since there is no tension between the finger gripping the tip, the force drawn toward the end that has not yet been cut acts. For this reason, if it is insufficient to sandwich the wrap film 91f between the front plate 12 and the lid cover piece 22, the wrap film 91f immediately after being cut approaches the end portion, and wrinkles are generated. There is a risk that it cannot be cut. According to the wrap carton 1 according to the present embodiment, since the area of the stopper 50 formed near the central region C of the main region M near the central portion in the width direction of the wrap film 91f is relatively large, The wrap film 91f near the center in the width direction can be suppressed so as not to skid. Still, since the stoppers 50 and the gaps 51g are alternately formed in the axial direction D, the wrap film 91f is not too closely attached to the stopper 50, and the wrap film 91f is torn vertically or cut obliquely. Can be suppressed. Further, since the flap 12f is formed in the main region M, the force that the flap 12f pushes the wrap film 91f toward the lid piece 22 acts as an auxiliary, and the wrap film 91f immediately after cutting is prevented from slipping. Will contribute. In the central region C, when the lid cover piece 22 is pushed toward the front plate 12 with the lid portion 20 closed, the lid cover piece 22 and the front plate 12 come into contact with each other. It can be suppressed so as not to skid. These actions are particularly advantageous for a relatively long lap carton of 250 mm or more, such as the wrap carton 1 of the present embodiment in which the length in the axial direction D is 310 mm.

  Since the wrap film 91f sandwiched between the flap 12f and the lid cover piece 22 after being cut is attached to the stopper 50, the wrap film 91f is prevented from being rewound onto the wrap roll 91r. Further, when the wrap film 91f is used next time, when the lid portion 20 is opened, the flap 12f floats outside the main body portion 10, so that the wrap film 91f attached to the stopper 50 formed on the flap 12f The tip also floats from the front plate 12 outside the flap 12f and is easy to pick. At this time, the stopper 50 formed in the central region C is lower in height than the stopper 50 formed in the main region M, and the stoppers 50 and the gaps 51g are alternately formed in the axial direction D. The wrap film 91f is not too close to the stopper 50. Therefore, the wrap film 91f is applied to the flap 12f in a direction away from the front plate 12 while being in close contact with the stopper 50 in the central region C, and the wrap film 91f is torn from the portion of the mountain and valley of the trace cut by the cutting blade 23. Can be prevented. In addition, since the flap 12f is not formed in the central region C of the wrap carton 1, a gap is formed between the central region C and the wrap film 91f. 91f can be picked. The center area C is between the left flap 12fA and the right flap 12fB, and corresponds to the central portion in the width direction of the wrap film 91f.

  Here, referring to FIG. 4 together with FIGS. 1 to 3, the operation of pulling out the wrap film 91f attached to the stopper 50 will be described. In pulling out the wrap film 91f picked between the left flap 12fA and the right flap 12fB, first, the wrap film 91f is turned away from the front plate 12 and peeled off from the stopper 50. At this time, the wrap film 91f attached to the stopper 50 along the front plate edge 19 in substantially the entire axial direction D has a portion of the wrap film 91f that has been picked and the wrap attached to the stopper 50. The tension T acts on an imaginary line connecting an arbitrary part of the film 91f. The tension T can be decomposed into a component Tp in the drawing direction P and a component Td in the axial direction D. In the wrap film 91f attached to the stopper 50, the pulling direction component Tp is larger and the axial direction component Td is smaller as the tension T is closer to the center in the width direction, and the pulling direction component Tp is smaller as the tension T is closer to the end. The axial component Td is small and large. For example, the tension T (E) acting on the end portion in the width direction of the wrap film 91f has a greater axial component Td than the tension T (F) acting on the center portion. Since the axial direction component Td generates a shearing force on the wrap film 91f, if the axial direction component Td becomes too large, the wrap film 91f may be broken. According to the wrap carton 1 according to the present embodiment, the area of the stopper 50 formed in the overlapping portion EFs is relatively small, and the stopper 50 and the gap 51g are alternately formed in the axial direction D in the overlapping portion EFs. Therefore, it is possible to suppress an increase in the axial direction component Td at the end, and it is possible to suppress damage to the wrap film 91f.

  As described above, according to the lap carton 1 according to the present embodiment, the total area of the stoppers 50 formed in the overlapping portion EFs is formed to be 30% to 60% of the area of the outer contact range Fs, and the outer side Since the stopper 50 is not formed outside the overlapping portion EFs in the contact range Fs, and the stopper 50 and the gap 51g are alternately formed in the axial direction D in the overlapping portion EFs, the wrap film 91f is in close contact with the stopper 50. It is not too much, and damage to the wrap film 91f can be suppressed.

  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 left flap 12fA and the right flap 12fB are formed on the front plate 12. However, the flap 12f is not formed at all, or one flap 12f may not be formed. Even if the flap 12f is not formed, damage to the wrap film 91f can be suppressed by forming the stopper 50 at a predetermined position in a predetermined manner. However, when the flap 12f is formed, the distance between the front plate 12 and the lid lid piece 22 when the lid portion 20 is closed becomes small and the wrap film 91f is likely to adhere to the stopper 50. The effect of preventing rewinding can be improved. As described above, when the flap 12f is not formed on the front plate 12, the entire covered region W having the width of the wrap film 91f in the axial direction D becomes the contact range F.

  In the above description, the belt-like region E is 2 mm away from the front plate edge 19 in the orthogonal direction R and extends in the axial direction D. However, the extent to which the belt-like region E is separated from the front plate edge 19 is It is not limited to being constant over the entire direction D, and may be variable within a range of 0.5 mm to 10 mm. In addition, although the belt-like region E extends in the axial direction D with a width of 9 mm in the orthogonal direction R, the width in the orthogonal direction R of the belt-like region E is not limited to be constant over the entire axial direction D. It may be variable in the range of 5 mm to 10 mm.

  In the above description, the stoppers 50 and the gaps 51g extending in the orthogonal direction R are continuously formed in the orthogonal direction R. However, like the main body 10A shown in FIG. Each stopper 50 and each gap 51g are divided into two in the orthogonal direction R by a dividing boundary line Ld extending linearly in the axial direction D (corresponding to a parallel direction), and the stopper 50 and the gap on the bottom plate 13 side from the dividing boundary line Ld 51 g may be formed to be shifted in the axial direction D by a half period (half the total width of the stopper 50 and the gap 51 g in the axial direction D). Here, extending in the axial direction D means that the ratio of the dividing boundary line Ld in the unit length to the length of the orthogonal direction R component in the length of the axial direction D component exceeds 1, preferably 3 or more. This is a mode in which the boundary line Ld extends. In the present modification, the dividing boundary line Ld is parallel to the axial direction D, and is provided at a position that bisects the height of the stopper 50 in the overlapping portion EFs (the length in the orthogonal direction R is about 9 mm). . In the main body 10A according to this modification, the stopper 50 and the gap 51g formed in the central region C are also divided into two in the orthogonal direction R, so that the stopper 50 and the gap 51g on the bottom plate 13 side are half-cycle in the axial direction D. It is formed by shifting. The other configuration of the main body 10A is the same as that of the main body 10 (see FIG. 2).

  The main body 10 shown in FIG. 2 is the first embodiment, the main body 10A shown in FIG. 5 is the second embodiment, and the main body 10X shown in FIG. The difficulty of slippage and the ease of peeling were measured and verified according to JIS Z-0237: 2009 “Testing method of adhesive tape / adhesive sheet”.

  FIG. 6 is a front view of the main body 10X. In the main body 10X, the stopper 50 on the flap 12f has a gap 51g between the stopper 50 and the gap 50g in the same manner as the main body 10 (see FIG. 2) on the central region C side from the position where the flap 12f is bisected in the axial direction D. Are alternately formed in the axial direction D in a manner extending in the orthogonal direction R with a width of about 3 mm in the axial direction D. The maximum length in the orthogonal direction R of the stopper 50 at this portion is about 15 mm. On the other hand, the stopper 50 extends in a strip shape in the axial direction D on the side plate 15 side from the position where the flap 12f is divided in half in the axial direction D. No gap 51g is formed in this portion, and the width of the stopper 50 in the orthogonal direction R is about 5 mm on the most central region C side, and gradually decreases from there to the side plate 15 side. It is about 3 mm on the side plate 15 side. Further, the main body 10X has a stopper 50 in the central region C and a stopper 50 between the flap 12f and the side plate 15, each having the same outline as the main body 10 (see FIG. 2), but there is a gap 51g. It is not formed and the stopper 50 is continuous.

  Difficulty and peeling of the wrap film 91f attached to the stopper 50 formed in a pattern such as the main body 10 (see FIG. 2), the main body 10A (see FIG. 5), and the main body 10X (see FIG. 6). The conditions for ease of verification are supplemented below. The stopper 50 was formed by irradiating a UV varnish with a predetermined pattern shown in each of the main body portions 10, 10A, and 10X by irradiating a high pressure mercury lamp to cure the coating film. The wrap film 91f is made of polyvinylidene chloride as a main raw material and includes a fatty acid derivative and an epoxidized vegetable oil and is formed to a thickness of about 15 μm (manufactured by Kureha Co., Ltd., trade name NEW Kurewrap (registered trademark)). It was. Tensilon used for the strength measurement described below was model number RTA-100 manufactured by Orientec Co., Ltd.

  First, the difficulty of shifting the wrap film 91f adhering to the stopper 50 (hereinafter referred to as “slip strength”) is shown. The shear strength was measured by the following procedure. First, the outer contact range Fs (see FIG. 3B) of each main body 10, 10A, 10X is cut out. A lap film 91f that has been cut to 25 mm × 100 mm in advance is placed on the cut out outer contact range Fs, and then a 2 kg rubber roller is reciprocated twice to bring it into close contact with the stopper 50. 24 hours after the wrap film 91f is brought into close contact with the stopper 50, each sample is fixed to the tensilon so that the normal of the surface of the outer contact range Fs is horizontal, and one end of the wrap film 91f is sandwiched between the tensilons. The shear strength is measured by moving the head at a head speed of 300 mm / min. At this time, for each of the two patterns in which the angles formed by the tension T and the axial direction component Td shown in FIG. 4 are 90 degrees and 45 degrees, each sample was measured five times. The temperature in the measurement chamber was 26 ° C. and the relative humidity was 53%.

  FIG. 7A shows the shear strength when the angle (see FIG. 4) formed by the tension T and the axial direction component Td is 90 degrees, and the shear strength when the angle formed by FIG. 7B is 45 degrees. , Respectively. The values shown in FIGS. 7A and 7B are forces (gf) immediately before the wrap film 91f is broken or just before the wrap film 91f is completely peeled from the stopper 50. From the results shown in FIGS. 7A and 7B, the shear strength of each of the main body portions 10, 10 </ b> A, and 10 </ b> X is substantially the same, and the shift of the wrap film 91 f from the stopper 50 in the first and second embodiments. The hardness was found to be equivalent to the comparative example.

  Next, ease of peeling of the wrap film 91f adhering to the stopper 50 (hereinafter referred to as “T-type peel strength”) will be described. T-type peel strength was measured by the following procedure. First, the entire front plate 12 is cut out from each main body 10, 10A, 10X. At this time, the portion of the flap 12f is fixed to the outer portion with tape from the back side. Next, the wrap film 91f having a width of 300 mm is cut into a size that can cover the entire front plate 12 in the orthogonal direction R. The cut wrap film 91f is overlapped so as to cover the entire front plate 12, and the 2 kg rubber roller is reciprocated twice so as to be brought into close contact with the stopper 50. 24 hours after the wrap film 91f is brought into close contact with the stopper 50, each sample is fixed to Tensilon so that the normal of the surface of the front plate 12 is vertical, and one end of the wrap film 91f on the bottom plate 13 side is fixed. The T-type peel strength is measured by being held between tensilons and moving at a head speed of 300 mm / min. Each sample was measured 5 times. The temperature in the measurement chamber was 23 ° C. and the relative humidity was 40 to 60%.

  FIG. 7C shows the measurement result of the T-type peel strength. The value shown in FIG. 7C is the force (gf) immediately before the wrap film 91f completely peels from the stopper 50. From the results shown in FIG. 7C, the average T-type peel strength is about 40% lower in Example 1 and Example 2 than in the comparative example. This suggests that Example 1 and Example 2 are easier to peel the wrap film 91f from the stopper 50 than the comparative example.

  Considering the measurement results of the above-mentioned shear strength and T-type peel strength comprehensively, Example 1 and Example 2 are lowering the adhesion force when peeling the wrap film 91f from the stopper 50 compared to the comparative example. It can be seen that the slip prevention performance at the time of cutting the wrap film 91f is maintained. As a result, Example 1 and Example 2 can suppress vertical tearing and oblique cutting while maintaining the cut property of the wrap film 91f.
