  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 front perspective view of the wrapping carton 100, and FIG. 1B is a partial rear perspective view showing the main body 10 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 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. 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. The sub-plate 16 is the front plate over the entire direction parallel to the front-plate end edge 19 (the same as the direction in which the axis 91a of the wrap roll 91r accommodated in the main body 10 extends, and hereinafter referred to as “axial direction D”). 12 are connected. 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 bent with respect to the front plate 12 at the front-plate end side 19 so as to overlap the front plate 12 and is in contact with the front plate 12 on the surface. 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. The cover plate 21 has one side in the axial direction D 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 wrap carton 1 having the basic structure as described above, the front plate 12 of the main body 10 includes a flap 12f. The flap 12f is formed by cutting the surface of the front plate 12 along the cutting line 12c. In the present embodiment, two flaps 12f are provided symmetrically with respect to a virtual straight line (not shown) that bisects the front plate 12 in the axial direction D. Each flap 12f is formed so as to be within the region of the front plate 12 covered with the lid cover piece 22 when the lid portion 20 is closed. A portion of the front plate 12 other than the flap 12f is referred to as a front plate body 12b. The front plate 12 includes a flap 12f and a front plate main body 12b. Each of the flaps 12f is configured to be connected to the sub plate 16 at the front plate edge 19 so that it does not fall off from the main body 10 even if it is cut along the cutting line 12c. Further, each of the flaps 12f is connected to the sub-plate 16 at the front plate end side 19, so that the front plate end side 19 can be rotated about the rotation axis, and is floated from the sub-plate 16 by this rotation ( In other words, it is configured to float from the front plate body 12b (project from the front plate body 12b).

  A stopper 50 as a locking means is formed substantially along the front plate edge 19 on the surface of each flap 12f. 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.

  Further, the wrap carton 1 having the basic structure as described above has a recess 17 (see FIG. 1B) formed on the inner side of the front plate 12 (the back side of the front plate 12) which is the inner side of the main body portion 10. Yes. The recesses 17 are formed at both ends in the axial direction D. In this embodiment, the recess 17 is formed by cutting out the sub plate 16. When the notch of the sub-plate 16 for forming the recess 17 is formed below the height of the flap 12f, it avoids the formation of a hole penetrating the inside and outside of the main body 10 in the front plate 12. Is preferable. In addition, since the dent 17 is formed in the size mentioned later in order to exhibit the intended function, the arrangement of the dent 17 has priority over the arrangement of the flap 12f. In other words, when the flap 12 f is formed above the recess 17, the flap 12 f may be formed in a range of a space that exists above the recess 17.

  Here, with reference to FIG. 2 together with FIG. 1, the recess 17 formed inside the main body 10 will be described. 2A is a partial front view showing the periphery of the recess 17 of the lap carton 1, and FIG. 2B is a partial cross-sectional view taken along the line BB in FIG. 2A. The recess 17 is formed in view of the following circumstances. The wrap film 91f pulled out from the wrap roll 91r accommodated in the main body 10 may sag. Further, the sagging wrap film 91f may be sandwiched between the wrap roll 91r and the main body 10 on the front plate 12 side. Even if the slack wrap film 91f is sandwiched, if there are dents 17 at both ends in the axial direction D of the main body 10, it can be avoided that both end portions in the axial direction D of the wrap film 91f are sandwiched between the both. it can. Therefore, generation | occurrence | production of the pressing force used as the starting point which the wrap film 91f tears diagonally from the end of the axial direction D can be avoided, and it can prevent that the wrap film 91f tears from the end of the axial direction D. As described above, the recess 17 is formed by cutting out the end of the sub-plate 16. Thereby, the dent 17 is configured to be recessed in a direction away from the lap roll 91r than the portion of the sub plate 16 positioned on the inner side in the axial direction D with respect to the portion where the sub plate 16 is cut out. .

  In this embodiment, the recess 17 is formed in a substantially quadrant shape. In the quadrant, the maximum height 17Hm that is the maximum height of the recess 17 and the maximum width 17Wm that is the maximum distance in the axial direction D of the recess 17 are not the same, and the contour of the notch It means that the arc is included. The dent 17 has a required height 17H and a required width 17W required to exhibit the function of the dent 17 inside the maximum height 17Hm and the maximum width 17Wm. The required height 17H has a required upper end 17Ht (see FIG. 2B), which is the upper end, at least from the center height 91ch, which is the height of the center of the unused lap roll 91r accommodated in the main body 10. Is also determined to be higher. The height difference 17Hd, which is the distance between the required upper end 17Ht and the center height 91ch, is preferably 1 mm or more, and more preferably 3 mm or more. As the height difference 17Hd increases, a step due to the dent 17 can be secured, so that the risk of the end portion in the axial direction D of the wrap film 91f being sandwiched between the wrap roll 91r and the main body portion 10 on the front plate 12 side is reduced. It is possible to prevent the wrap film 91f from tearing from the end in the axial direction D.

  The required width 17W is formed in such a length that the end portion 91re (see FIG. 1A) in the axial direction D of the wrap roll 91r does not contact the main body portion 10. If the end portion 91re of the wrap roll 91r is assumed to be sandwiched between the end portion 91re of the wrap roll 91r and the main body portion 10, the tip end of the wrap film 91f is axially This is the portion of the wrap roll 91r that causes the wrap film 91f to be obliquely cut when it is picked at the center portion D and the wrap film 91f is pulled out. The required width 17W may be determined within a range in which the end 91re of the wrap roll 91r does not contact the main body 10 when the wrap roll 91r is accommodated in the main body 10. The required width 17W may be, for example, 15 mm, 20 mm, 30 mm, or 2% to 10% of the length in the axial direction D of the wrap roll 91r. The required width 17W is preferably not too large from the viewpoint of suppressing a decrease in strength of the front plate 12.

  The dent 17 has a required height 17H and a required width 17W, and is expanded to a maximum height 17Hm and a maximum width 17Wm, so that the end in the axial direction D of the wrap film 91f is on the lap roll 91r and the front plate 12 side. The risk of being sandwiched between the main body 10 and the wrap film 91f can be prevented from tearing from the end in the axial direction D. In addition, the recess 17 is not formed in a rectangular shape having a maximum height of 17 Hm and a maximum width of 17 Wm, but is formed in a quadrant so that the respective functions of the recess 17 and the flap 12 f are exhibited. Interference between the recess 17 and the flap 12f can be avoided. Further, the depth of the recess 17 (the distance in the thickness direction of the material constituting the main body 10) is preferably 0.4 mm or more, and more preferably 0.7 mm or more. As the depth of the recess 17 increases, a step due to the recess 17 can be secured, so that the end in the axial direction D of the wrap film 91f is sandwiched between the wrap roll 91r and the main body 10 on the front plate 12 side. The risk can be reduced, and the wrap film 91f can be more effectively prevented from tearing from the end in the axial direction D.

  FIG. 3 shows a development view of the wrap carton 1. In the present embodiment, the main body 10 and the lid 20 are formed by bending a coated cardboard having a thickness of about 0.45 to 0.7 mm, punched into a predetermined mold shown in FIG. Yes. 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.

  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 sub-plate 16, the front plate 12, the bottom plate 13, the rear plate 14, the cover plate 21, and the lid cover piece 22 are arranged in this order, and adjacent members are connected over the entire axial direction D. Further, a cut piece 29 is connected to the outside of the lid cover piece 22 through a perforation 29c. The sub-plate 16, the front plate 12, the bottom plate 13, and the rear plate 14 are bent along a folding line extending in the axial direction D, and the joining piece 12 j, the joining piece 14 j, and the side plate 15 are each orthogonal to the axial direction D. The joint piece 12j is overlapped and adhered to the outside of the joint piece 14j, and the side plate 15 is further overlapped and adhered to the outside thereof, thereby forming the rectangular parallelepiped body portion 10. Has been. 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 located between the sub-plate 16 and the front plate 12 as seen in the development view shown in FIG. And the sub-plate 16 is bonded to the front plate 12, and is bent between the bottom plate 13 and the rear plate 14, and between the lid plate 21 and the lid cover piece 22, and the lid cover piece 22 and the cut piece 29 are joined to the front plate. The cut pieces 29 are stacked on the front plate 12 and folded into a flat shape in which the cut pieces 29 are bonded to the front plate 12 at a plurality of points. The folded wrap carton 1 is in a state where the side plate 15 and the joining pieces 12j, 14j, and 22j are not joined. The folded wrap carton 1 is formed by peeling the joining pieces 12j, 14j, and 22j from the wrap carton 1 and flattening them. In order to improve manufacturing efficiency, the folded wrap carton 1 is not assembled and temporarily folded. Generally, it is manufactured so that Even in this case, the folded wrap carton 1 can be regarded as one form of the wrap carton 1 because it originally exhibits its existence in an assembled state. The folded wrap carton 1 is first formed into a rectangular tube shape with both ends opened at the manufacturing site of the wrapping carton 100. After the wrap roll 91r is inserted from one end surface, the side plate 15 is closed. It becomes a carton 100 with a wrap.

  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.

  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, the wrap film 91f is sandwiched between the flap 12f that floats outward and the lid cover piece 22 of the closed lid 20 and is formed along the front plate edge 19. Therefore, the movement is regulated, so that it is appropriately cut without skidding.

  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 is lifted from the front plate body 12b. Therefore, the tip of the wrap film 91f attached to the stopper 50 formed on the flap 12f. Will float from the front plate body 12b and is easy to pick. In particular, since the wrap carton 1 does not have the flap 12f formed between the left and right flaps 12f, the wrap film 91f can be easily picked by putting a finger into this gap. The wrap film 91f that is pulled out from the wrap roll 91r and has the tip attached to the stopper 50 is normally in a tight state. However, for some reason, a large amount of the wrap film 91f is pulled out from the wrap roll 91r, and the wrap film 91f between the tip of the wrap film 91f adhering to the stopper 50 and the wrap roll 91r becomes slack. Sometimes. At this time, the sagging wrap film 91f may enter the main body 10 and be sandwiched between the wrap roll 91r and the main body 10 (see FIG. 4A). Conventionally, in this state, when trying to use the wrap film 91f, if the tip of the wrap film 91f is peeled off from the stopper 50 and the wrap film 91f is to be pulled out from the wrap roll 91r, the wrap film 91f is inclined from the end in the axial direction D. There was a case of tearing. However, according to the wrapping carton 100 according to the present embodiment, the dent 17 is formed in the lap carton 1 where the wrap film 91f can be sandwiched between the end portion 91re of the wrap roll 91r and the main body portion 10. Yes. Therefore, even if the wrap film 91f sags and enters the main body portion 10, the wrap film 91f can be prevented from being sandwiched between the end portion 91re of the wrap roll 91r and the main body portion 10. Thereby, generation | occurrence | production of the diagonal tear of the wrap film 91f can be prevented.

  The reason why the dent 17 is formed in the wrap carton 1 is as follows. The present inventors have found that the above-described oblique tearing of the wrap film 91f can be caused by the wrap film 91f being sandwiched between the end portion 91re and the main body portion 10 of the wrap roll 91r. This is presumably due to the following reasons. First, when the slack wrap film 91f is sandwiched between the wrap roll 91r and the main body portion 10 in the entire axial direction D, when the wrap film 91f is picked and pulled out, a tensile stress in the pull-out direction P is generated in the wrap film 91f. . The tensile stress T can be decomposed into a component Tp in the drawing direction P and a component Td in the axial direction D (see FIG. 4B). In the wrap film 91f sandwiched between the wrap roll 91r and the main body portion 10, the pulling direction component Tp is larger and the axial direction component Td is smaller as the tensile stress T in the portion closer to the center in the axial direction D is smaller. As the stress T increases, the pull-out direction component Tp decreases and the axial direction component Td increases. For example, the tensile stress T (E) acting on the end portion of the wrap film 91f in the axial direction D has a larger axial component Td than the tensile stress T (F) acting on the central portion. Become. Since the axial direction component Td generates a shearing force on the wrap film 91f, when the wrap film 91f is sandwiched by the end portion 91re where the axial direction component Td increases and a tensile stress T is applied, the lap film 91f is obliquely cracked. It is assumed that will occur. In the wrapped carton 100 according to the present embodiment, the wrap film is formed between the end portion 91re of the wrap roll 91r and the main body portion 10 by forming the recesses 17 at both ends in the axial direction D on the back side of the front plate 12. It is avoided that 91f is pinched. Thereby, generation | occurrence | production of the pressing force used as the starting point which the wrap film 91f tears diagonally can be avoided, and it can prevent that the wrap film 91f tears diagonally.

  As described above, according to the wrap carton 1 and the wrap-containing carton 100 according to the present embodiment, the wrap carton 1 that can sandwich the wrap film 91f between the end portion 91re of the wrap roll 91r and the main body portion 10 is provided. Since the dent 17 is formed at the place, even if the wrap film 91f sags and enters the main body portion 10, the wrap film 91f is sandwiched between the end portion 91re of the wrap roll 91r and the main body portion 10. This can be avoided, and the occurrence of oblique tearing of the wrap film 91f can be prevented.

  In the above description, the recess 17 is formed by cutting out both ends in the axial direction D of the sub-plate 16. However, the sub-plate 16 (sub-surface) facing the inner portion of the end portion 91re of the wrap roll 91r is formed. When the plate 16 is not provided, a protrusion is formed on the back side of the front plate 12 so as to approach the lap roll 91r, so that the sub plate 16 (or the back side of the front plate 12) facing the end 91re is relatively Alternatively, it may be formed so as to be recessed. In addition, when forming a protrusion so that it may approach the lap roll 91r, as shown in FIG. 5, a protrusion is formed with the embossing 16p formed by embossing the sub-plate 16 (or front plate 12). Alternatively, instead of embossing, the protruding portion may be formed by attaching paperboard or the like to the sub-plate 16 (or the back side of the front plate 12). Alternatively, as shown in FIG. 6, the protruding portion may be formed of a sub-subplate 16 t formed by folding the sub-plate 16 at the lower end.

  In the above description, the recess 17 is formed on the inner side of the main body 10 corresponding to the front plate 12, but the slack wrap film 91f is between the end 91re of the wrap roll 91r and the rear plate 14. When it can be pinched, it is preferable that a recess 17 is also formed inside the main body 10 corresponding to the rear plate 14. Similarly, when the sagging wrap film 91f can be sandwiched between the end 91re of the wrap roll 91r and the bottom plate 13, a recess 17 may be formed inside the main body 10 corresponding to the bottom plate 13. preferable.

  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, a pair of flaps 12f are formed on the front plate 12. However, one flap 12f may not be formed, or three or more flaps 12f may be formed. Furthermore, the arrangement and size of the provided flaps 12f can be determined as appropriate. In addition, when the dent 17 does not interfere with the flap 12, the dent 17 that has been formed in a quadrant shape in the above description has a height of 17H or higher and a width of 17W or higher. It may be formed by cutting out into a rectangular shape, and the upper end when cut out into a rectangular shape may coincide with the front plate edge 19. In other words, in the above description, the sub-plate 16 is connected to the front plate 12 over the entire axial direction D. Instead of the above-described mode, the sub-plate 16 is disposed inside the main body portion 10 with a length excluding the portion of the sub-plate 16 facing the end portion 91re of the wrap roll 91r.
