Description

  The present invention relates to a wound body storage box and a storage box with a wound body, and more particularly to a wound body storage box and a storage body with a wound body that prevent a flap that floats a film from rising excessively.

  Food wrap films that wrap food, dishes, or dishes such as dishes with each dish are widely used. A food wrap film is typically stored in a long rectangular container (container box) in which a long plastic film (rolled body) wound in a roll is formed by folding paperboard. In use, the film at the tip is pulled out from the roll by the required amount and cut with a cutting blade attached to the lid of the container. From the viewpoint of improving the convenience of the user, as a container that makes it easy to pick up the wrap film, a flap is provided that opens to the outside with the upper side of the box front wall as the base axis by cutting into the upper part of the box front wall of the box body constituting the container, When the lid is closed, the flap is covered with the lid front wall of the lid, and when the lid is opened, there is one that separates the tip of the wrap film from the box front wall (see, for example, Patent Document 1). ).

  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 connected to the front plate 12 over the entire direction parallel to the front plate edge 19 (the same as the direction in which the axis 91a of the wrap roll 91r extends, hereinafter referred to as “axis 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 bent with respect to the front plate 12 at the front-plate end side 19 so as to be in contact with the front plate 12 on the surface. In this specification, when the sub-plate 16 is in contact with the front plate 12 in a plane, the entire surface of the sub-plate 16 is conceptually in contact with the surface of the front plate 12, in other words, the sub-plate 16. Is bent 180 degrees with respect to the front plate 12. Strictly speaking, even if the vicinity of the front plate edge 19 is bent and rebounded (restoring force), the sub plate 16 and the front plate 12 are not in contact with each other. It can be seen that they are substantially in contact, and such a state is also included in “contact with a 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 an outer flap 12f. The outer flap 12f is formed by cutting the surface of the front plate 12 along a cut line 12c as a front plate cut line. In the present embodiment, two outer flaps 12f are provided symmetrically about a virtual straight line (not shown) that bisects the front plate 12 in the axial direction D. For the convenience of explanation, the two outer flaps 12f are viewed from the front (when viewed from the front plate 12 facing forward), the left outer flap 12f is the left outer flap 12fA, and the right outer flap 12f is the right outer. It is assumed that the flap is 12 fB. The left outer flap 12fA and the right outer flap 12fB correspond to a first outer flap and a second outer flap, respectively. Hereinafter, when a configuration common to the left outer flap 12fA and the right outer flap 12fB is described, they are simply collectively referred to as “the outer flap 12f”. Further, the side plate 15 close to the left outer flap 12fA may be called the left side plate 15A (first side plate), and the side plate 15 close to the right outer flap 12fB may be called the right side plate 15B (second side plate). The side plate 15 is a general term for these. Both the left outer flap 12fA and the right outer flap 12fB are formed so as to be within the region of the front plate 12 covered with the lid lid 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.

  The left outer flap 12fA is contoured by a cut line 12cA formed in the plane of the front plate 12 and the front plate end side 19. 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 center in the axial direction D of the front plate 12, and passes through the front plate 12 from a point on the front plate end side 19 and is close to the left side plate 15A. It is formed by cutting the surface of the front plate 12 so as to reach a point on the side 19. Both ends of the cutting line 12cA are separated from each other in the axial direction D, and both are hooked on the front plate edge 19. The maximum length of the left outer flap 12fA in the height direction is formed to be about ½ of the length of the front plate 12 in the height direction. In the present embodiment, the lower side of the left outer flap 12fA once again approaches the left side plate 15A side from the center in the axial direction D of the front plate 12 and then once again approaches the front plate edge 19 again. It is formed in a smooth curve that separates from the front plate edge 19. In other words, the center portion of the left outer flap 12fA is slightly recessed above both ends. Since both ends of the cut line 12cA constituting the outline of the left outer flap 12fA reach the front plate end side 19, the left outer flap 12fA can be floated from the sub plate 16 by a considerable amount. The left outer flap 12fA is connected to the sub-plate 16 at the front plate edge 19 so that the left outer flap 12fA does not fall off from the main body 10 even if it is cut along the cutting line 12cA. Further, since the left outer flap 12fA is connected to the sub plate 16 at the front plate end side 19, it can be rotated about the front plate end side 19 as a 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 main body 12b (project from the front plate main body 12b) so as to be separated from the sub plate 16.

  A stopper 50 as a locking means is formed on the surface of the left outer flap 12fA 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 right outer flap 12fB, which is provided symmetrically with the left outer flap 12fA, has a cut line 12cB formed in the plane of the front plate 12 and the front plate edge 19 as an outline. When the cut line 12cA and the cut line 12cB are not distinguished (typically when the generic outer flap 12f is described), the cut line 12cA and the cut line 12cB are simply referred to as a “cut line 12c”. Also on the right outer flap 12fB, the stopper 50 is formed in a line-symmetric manner with respect to the left outer flap 12fA. The stopper 50 is also provided between the left outer flap 12fA and the right outer flap 12fB, between the left outer flap 12fA and the left side plate 15A, and between the right outer flap 12fB and the right side plate 15B. It is formed along the end side 19.

  Here, the inner flap 16f included in the sub-plate 16 will be described with reference to FIG. 2 together with FIG. 2A is a partial front view showing the periphery of the inner flap 16f of the wrap carton 1, and FIG. 2B is a partial side sectional view of the wrap carton 1. As shown in FIG. The inner flap 16f is formed by cutting the surface of the sub-plate 16 along a cut line 16c as a sub-plate cut line. In the present embodiment, as shown in FIG. 1B, two inner flaps 16f are provided. For convenience of explanation, the inner flap 16f on the back side of the left outer flap 12fA is referred to as the left inner flap 16fA, and the inner flap 16f on the back side of the right outer flap 12fB is referred to as the right inner flap 16fB. . When a configuration common to the left inner flap 16fA and the right inner flap 16fB is described, it is simply referred to as an “inner flap 16f”.

  As shown in FIG. 2A, in the present embodiment, the inner flap 16f is provided at a position included in the outer flap 12f when projected onto the front plate 12. In the present embodiment, the length between both ends of the cut line 12c in the axial direction D (hereinafter referred to as “outer flap length 12W”) is the length of the front plate 12 in the axial direction D for one outer flap 12f. The length between both ends of the cutting line 16c in the axial direction D (hereinafter referred to as “inner flap length 16W”) per one inner flap 16f is the axis of the front plate 12. The length in the direction D is about 0.25 times. The inner flap length 16W is about 0.65 times (13/20) the outer flap length 12W. In other words, the inner flap 16f covers 13/20 of the outer flap 12f in the axial direction D. Here, the term “cover” means a state in which a part of the outer flap 12f is hidden by the inner flap 16f when the inner flap 16f is projected onto the front plate 12, and in this embodiment, the outer flap is hidden. A portion of the outer flap 12f corresponding to 13/20 of the length 12W is hidden by the inner flap 16f.

  In the inner flap 16f having such an inner flap length 16W, both ends of the cutting line 16c are separated from each other in the axial direction D. The cut line 16c is formed so that each end portion thereof is located in a region of the sub plate 16 sandwiched between the front plate end side 19 and the boundary line B. The front plate edge 19 and the boundary line B are the outer edges of this region. The boundary line B is an imaginary straight line on the sub-plate 16 that is parallel to the front plate edge 19 and is 8 mm away from the front plate edge 19 in a direction perpendicular to the front plate edge 19. In the present embodiment, the cut line 16c swells toward the bottom plate 13 between both ends, and the maximum length of the inner flap 16f in the height direction is about 1/5 of the length of the front plate 12 in the height direction. Is formed. The sub plate 16 is bonded to the front plate 12 below the bottom point of the outer flap 12f (on the bottom plate 13 side). In other words, the outer flap 12 f is not bonded to the sub-plate 16, and the inner flap 16 f is not bonded to the front plate 12. By being configured in this way, the outer flap 12f cut along the cut line 12c can float from the sub-plate 16, and the inner flap 16f cut along the cut line 16c protrudes from the other sub-plates 16 can do.

  Further, the inner flap 16f has both ends of the cut line 16c positioned on the virtual straight line VL. The virtual straight line VL is assumed to be included in the region of the sub-plate 16 sandwiched between the front plate edge 19 and the boundary line B, is parallel to the front plate edge 19, and extends from the front plate edge 19 to the bottom plate 13. This is a virtual straight line on the sub-plate 16 having a predetermined distance H on the side. The predetermined distance H is such that the smaller the inner flap 16f is, the easier it is to float, and the smaller the predetermined distance H is, the more difficult it is to float the inner flap 16f. There is a virtual straight line VL on the sub-plate 16, and from the viewpoint of preventing the floating of the inner flap 16f from becoming too large, it should be 2 mm or more. In this embodiment, it is 3 mm. Further, the virtual straight line VL has a width of approximately 2 to 3 mm, and the distance between the both ends of the cut line 16c and the front plate end side 19 may be different within the range of the width. In the present embodiment, the end of the cutting line 16c on the side plate 15 side has a shortest distance to the front plate edge 19 of 4.0 mm, and the end on the center has a shortest distance of 2 to the front plate edge 19. .5mm.

  As shown in FIG. 2B, with the above-described configuration, the outer flap 12f floats outward and the inner flap 16f floats inward. The inventors of the present invention have a force (restoring force) repelling each other around the front plate end side 19 between the outer flap 12f and the inner flap 16f bent at the front plate end side 19, and the outer flap 12f acts on the outer flap 12f. The rise S of 12f (vertical distance to the front end of the outer flap 12f with respect to the surface of the front plate body 12b in the cross section perpendicular to the axis) is related to the floating amount of the inner flap 16f, and this principle is used. Thus, it has been conceived that the rising S of the outer flap 12f is made appropriate by adjusting the floating amount of the inner flap 16f. The rising S of the outer flap 12f is larger as the inner flap length 16W is smaller, and is smaller as the inner flap length 16W is larger. Therefore, the inner flap length 16W is not less than 1/4 and not more than 3/4 of the outer flap length 12W. Is preferred. Further, the appropriate predetermined distance H is determined from the viewpoint that the rising S of the outer flap 12f is appropriate, but it is preferable to adjust appropriately within the range of 0 to 8 mm, and the rising of the outer flap 12f. 3 mm or more is preferable from the viewpoint of preventing S from becoming excessive, and 5 mm or less is preferable from the viewpoint of preventing the rising S of the outer flap 12f from becoming excessively small.

  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 and generates the repulsive force of the outer flap 12f and the inner flap 16f described above. 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, and the side lid piece 25 and the joining piece 22j are each bent along a folding line extending in a direction perpendicular to the axial direction D, As described above, the three-dimensional lid portion 20 is formed by overlapping and bonding the side lid pieces 25 on the outside of the joining piece 22j.

  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. In the present embodiment, since the inner flap 16f is provided by forming the cut line 16c in the sub-plate 16, the restoring force (repulsive force) of the outer flap 12f bent at the front plate end side 19 is obtained. The outer flap 12f can escape to the inner flap 16f, and the outer flap 12f does not float (project) excessively from the front plate body 12b, and the cut piece 29 before excision is peeled off by the restoring force of the outer flap 12f in an unopened state. Can be avoided. When using the wrap film 91f of the wrapped carton 100 that has been distributed without damaging the wrap carton 1 and is in the hands of the consumer, the cut piece 29 is cut off at the perforation 29c while peeling off the front plate 12. Then, it is separated from the lid 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, the wrap film 91f is sandwiched between the outer 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 Since the movement is regulated by 50, it is cut appropriately without skidding.

  Since the wrap film 91f sandwiched between the outer flap 12f and the lid lid 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 outer flap 12f is lifted from the front plate body 12b as the inner flap 16f is appropriately formed. The tip of the wrap film 91f adhering to the stopper 50 formed on the top is also lifted from the front plate body 12b, and is easy to pick. In particular, since the outer flap 12f is not formed between the left outer flap 12fA and the right outer flap 12fB in the wrap carton 1, the wrap film 91f can be easily picked by putting a finger into this gap.

  As described above, according to the wrapped carton 100 according to the present embodiment, since the appropriate cut line 16c is formed in the sub-plate 16, the outer flap 12f is appropriately lifted from the front plate body 12b. Thus, damage to the wrap carton 1 due to the restoring force of the outer flap 12f can be prevented, and the ease of picking the wrap film 91f can be ensured.

  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 outer flap 12fA and the right outer flap 12fB are formed on the front plate 12. However, one outer flap 12f may not be formed, or three or more outer flaps 12f may be formed. It may be formed, and the arrangement and size of the provided outer flap 12f can be determined as appropriate.

  In the above description, two inner flaps 16f are also provided so as to correspond to each of the two outer flaps 12f. However, one of the two axial directions D in the axial direction D with respect to the two outer flaps 12f. The number of the outer flaps 12f and the number of the inner flaps 16f may not correspond to each other, for example, by providing one long inner flap 16f in the axial direction D that covers a length of / 5 or more. For example, a plurality of inner flaps 16f are provided for one outer flap 12f, and the total length of the plurality of inner flaps 16f in the axial direction D is 1/5 or more of the length of the outer flap 12f in the axial direction D. You may be comprised so that it may become.

  In the above description, the sub-plate 16 includes the inner flap 16f in which the inner portion cut by the cutting line 16c floats inside the main body portion 10. However, the inner flap that floats inside the main body portion 10 is used. 16f is not formed, and the cut line 16c having a length of 1/5 or more of the length of one outer flap 12f in the axial direction D is linearly or curvedly (including wavy lines, zigzag lines, etc.) It is good also as a structure which escapes a part of repulsive force of the outer flap 12f to the subplate 16 side by forming in the position facing the flap 12f. Also in this case, both ends of the cutting line 16c are located in the region of the sub plate 16 sandwiched between the front plate end side 19 and the boundary line B. In particular, when the cutting line 16c is a straight line, the entire cutting line 16c is located in the region of the sub-plate 16 sandwiched between the front plate edge 19 and the boundary line B.

  In the above description, the inner flap 16f is provided at a position included in the outer flap 12f when projected onto the front plate 12, but when projected onto the front plate 12, one outer flap length 12W. If the inner flap 16f and the outer flap 12f overlap with each other at 1/5 or more, the inner flap 16f may be extended to the outside of the outer flap 12f (the front plate body 12b portion). The same applies to the case where the straight or curved cut line 16c is formed without forming the inner flap 16f that floats inside the main body 10.

  In the above description, the both ends of the cut line 16c are positioned on the virtual straight line VL. However, each end of the cut line 16c is formed on the sub-plate 16 sandwiched between the front plate end side 19 and the boundary line B. Within the region, the distance from the front plate edge 19 can be determined as appropriate. As an extreme example, one end of the cut line 16c may be positioned on the front plate end side 19 and the other end may be positioned on the boundary line B. When the difference in distance between each end of the cutting line 16c and the front plate end side 19 in the direction orthogonal to the front plate end side 19 increases, the degree to which the outer flap 12f floats from the front plate main body 12b when viewed in the axial direction D The bias becomes larger. That is, of the two ends of the cutting line 16c, the shorter the distance to the front plate edge 19 is, the longer the corresponding portion of the outer flap 12f on the back side floats from the front plate body 12b. The degree increases. In other words, by adjusting the difference in distance between each end of the cutting line 16c and the front plate edge 19, the deviation of the degree to which the outer flap 12f as seen in the axial direction D floats from the front plate body 12b is adjusted. be able to. If the both ends of the cut line 16c are configured to be on the virtual straight line VL, it is possible to suppress the deviation of the degree that the outer flap 12f floats from the front plate body 12b.

  Below, the result of having verified the change of the rising S of the outer flap 12f with respect to the change of the inner flap length 16W is shown. The wrap carton 1 used for this verification has a length in the axial direction D of 310 mm, and a height and a depth of 44 mm each. Further, as shown in FIG. 1A, two outer flaps 12f are provided symmetrically, and the outer flap length 12W is 120 mm, the maximum height is 20 mm, and the left outer flap 12fA and the right outer flap 12fB are There is a gap of 40 mm. The wrap carton 1 is formed by processing a coated cardboard having a thickness of 0.7 mm. Several types of lap carton 1 having the above basic conditions were prepared by changing the inner flap length 16W of the inner flap 16f provided on the sub plate 16. Note that the cut line 16c forming the inner flap 16f has both ends reaching the front plate edge 19 (that is, the predetermined distance H is 0), and the maximum height of the inner flap 16f is 10 mm. Even if the inner flap length 16W is different, the inner flap 16f has a virtual straight line that bisects the inner flap length 16W in the axial direction D matches a virtual straight line that bisects the outer flap length 12W in the axial direction D. Is provided.

Example 1
In Example 1, the inner flap length 16W was set to 30 mm. At this time, the percentage of the inner flap length 16W to the outer flap length 12W is 25%. In Example 1, the rising S of the outer flap 12f was 3.2 mm.
(Example 2)
In Example 2, the inner flap length 16W was set to 75 mm. At this time, the percentage of the inner flap length 16W to the outer flap length 12W is approximately 62%. In Example 2, the rising S of the outer flap 12f was 2.5 mm.
(Example 3)
In Example 3, the inner flap length 16W was 90 mm. At this time, the percentage of the inner flap length 16W to the outer flap length 12W is 75%. In Example 3, the rising S of the outer flap 12f was 2.0 mm.

(Comparative Example 1)
In Comparative Example 1, the inner flap length 16W was set to 0 mm (that is, the inner flap length 16f was not provided) (therefore, the percentage of the inner flap length 16W to the outer flap length 12W was 0%). In Comparative Example 1, the rising S of the outer flap 12f was 4.8 mm.
(Comparative Example 2)
In Comparative Example 2, the inner flap length 16W was 110 mm. At this time, the percentage of the inner flap length 16W to the outer flap length 12W is about 92%. In Comparative Example 2, the rising S of the outer flap 12f was 0.7 mm.

  FIG. 4A collectively shows the conditions and results of Examples 1 to 3 and Comparative Examples 1 and 2. When the usage conditions of Examples 1 to 3 were observed, the leading end of the wrap film 91f that was pulled out and placed on the outer flap 12f was sufficiently separated from the front plate body 12b by the outer flap 12f, and the wrap film 91f. It was easy to pick. Further, when the lid portion 20 was closed, it was determined that the lifting of the lid cover piece 22 due to the repulsive force of the outer flap 12f was not excessive, and the lap carton 1 before opening was not damaged by the repulsive force of the outer flap 12f. . From the above verification, according to the first to third embodiments, it can be said that the rising S of the outer flap 12f is in an appropriate range.

  On the other hand, in Comparative Example 1, the rising S of the outer flap 12f was large, and it was sufficient to grab the leading end of the drawn wrap film 91f, but the lifting of the lid piece 22 when the lid portion 20 was closed was large, There was a concern that the lap carton 1 before opening was damaged by the repulsive force of the outer flap 12f. In Comparative Example 2, the rising S of the outer flap 12f was small, the separation of the front end of the wrap film 91f from the front plate body 12b was insufficient, and the wrap film 91f was difficult to pick.

  Next, without changing the outer dimensions and material of the wrap carton 1 and the configuration of the outer flap 12f, the inner flap length 16W is fixed to 75 mm (therefore, the percentage of the inner flap length 16W to the outer flap length 12W is about 62%). Several types were prepared by changing the distance (predetermined distance H) from the front plate edge 19 at both ends of the cutting line 16c. The shortest distance from the front plate edge 19 to the lowest part of the inner flap 16f is fixed to 10 mm. Moreover, the distance from the front-plate edge 19 of the both ends of the cutting line 16c shown below is the same at both ends of the cutting line 16c.

Example 4
In Example 4, the distance from the front plate edge 19 at both ends of the cutting line 16c (hereinafter referred to as “predetermined distance H”) was 3 mm. In Example 4, the rising S of the outer flap 12f was 2.8 mm.
(Example 5)
In Example 5, the predetermined distance H was 5 mm. In Example 5, the rising S of the outer flap 12f was 3.4 mm.
(Example 6)
In Example 6, the predetermined distance H was 8 mm. In Example 6, the rising S of the outer flap 12f was 3.7 mm.
(Comparative Example 3)
In Comparative Example 3, the predetermined distance H was 12 mm. In Comparative Example 3, the rising S of the outer flap 12f was 4.6 mm.

  FIG. 4B summarizes the conditions and results of Examples 4 to 6 and Comparative Example 3. When the usage conditions of Examples 4 to 6 were observed, the tip of the wrap film 91f was sufficiently separated from the front plate body 12b, and it was easy to pick up the wrap film 91f. Further, it was determined that when the lid 20 was closed, the lid cover piece 22 was not lifted up excessively by the repulsive force of the outer flap 12f, and the wrap carton 1 before opening was not damaged by the repulsive force of the outer flap 12f. . From the above verification, according to Examples 4 to 6, it can be said that the rising S of the outer flap 12f is in an appropriate range. On the other hand, in Comparative Example 3, since the rising S of the outer flap 12f is large, the lid cover piece 22 is lifted greatly when the lid 20 is closed, and the lap carton 1 before opening is damaged by the repulsive force of the outer flap 12f. There was concern.

  From the results of the verification described above, it was confirmed that the rising S of the outer flap 12f can be adjusted by adjusting the inner flap length 16W or by adjusting the predetermined distance H. Further, the inner flap length 16W is preferably 1/4 or more and 3/4 or less of the outer flap length 12W, and the predetermined distance H is preferably 8 mm or less.
