  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. FIG. 1A is a front perspective view of a wrapping carton 100, and FIG. 1B is a front view of the wrapping carton 1. 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 protrudes to the outside of the main body 10 and the tip is directed to the bottom plate 13 side. The protrusions 15p are provided on the side plate top side 17 at the upper end of each of the two side plates 15. The side plate top side 17 is a top side (end side) of the side plate 15 where the side plate 15 and the opening surface 10 h intersect. Further, the main body 10 has a sub-plate (not shown) that is continuous with the front plate 12 at the front plate edge 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 in this embodiment also serves as a boundary between the front plate 12 and the sub-plate (not shown). . The sub-plate (not shown) is the whole in the direction parallel to the front plate 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 “axis direction D”). Is connected to the front plate 12. The sub-plate (not shown) 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 (not shown) is bent with respect to the front plate 12 at the front plate edge 19 so as to overlap the front plate 12 and is in contact with the front plate 12 on the surface. The sub-plate (not shown) has an end on the bottom plate 13 side bonded to the front plate 12 along the axial direction D.

  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 is connected to the lid plate 21 in the entire axial direction D. 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. The tip side 22t that faces the bent side 21f, except for both ends in the axial direction D, is bent side 21f in the direction orthogonal to the axial direction D as it moves from the center in the axial direction D to each end. And the distal end side 22t are formed to be short. With this configuration, the tip side 22t at the center in the axial direction D is formed so as to protrude toward the bottom plate 13 when the lid 20 is closed. The central portion in the axial direction D here is a range of １ ／ of the length in the axial direction D of the lid piece 22. In the present embodiment, except for both end portions in the axial direction D, the tip side 22t protrudes toward the bottom plate 13 side, including the outside of the central portion in the axial direction D. Both ends in the axial direction D of the tip side 22t are lowered (formed so as to approach the bottom plate 13). With such a configuration, the tip side 22t facing the bent side 21f is formed in a substantially 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. In other words, when the lid portion 20 is closed, the lid cover piece 22 has the opening surface 10h side when the front plate 12 is virtually divided by a virtual straight line VL parallel to the front plate edge 19 (parallel to the axial direction D). The front plate 12 is configured to cover the entire axial direction D. The position of the virtual straight line VL is assumed to be about ½ of the height of the front plate 12 in the present embodiment where the shortest height of the lid piece 22 is about ½ of the height of the front plate 12. However, it can be appropriately changed according to the shape of the lid lid piece 22. 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 (a folded line 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. That is, the concave portion 25d functions as a gap into which the protrusion 15p is fitted when the lid portion 20 is closed. The recess 25d is formed between the joining piece 22j and the top side 25s. The top side 25 s is a line of intersection between the lid plate 21 and the side lid piece 25. In the present embodiment, the joining piece 22j corresponds to a step forming piece. 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.

  Here, with reference to FIG. 2 (A), the periphery of the end portion of the lid cover piece 22 will be described in detail. FIG. 2A is a partial front view of the wrap carton 1. In the wrap carton 1, the front end side 22t of the lid cover piece end portion 22e approaches the bottom plate 13 side as it goes outward in the axial direction D. In other words, the lid cover piece end portion 22e has an average length in the height direction of a portion of the lid cover piece 22 on the inner side in the axial direction D with respect to the lid cover piece end portion 22e, and a height of a portion adjacent to the lid cover piece end portion 22e. It is formed longer than the average length in the direction. The lid cover piece end portion 22e is an end portion of the lid cover piece 22 in the axial direction D, and typically the wrap film 91f is pulled out from the wrap roll 91r accommodated in the main body portion 10 to close the lid portion 20. This is the portion of the lid piece 22 that is outside the width of the drawn wrap film 91f. Further, the portion adjacent to the lid cover piece end portion 22e is a cover from the boundary with the lid cover piece end portion 22e to a position that is inside the axial direction D by a length corresponding to the length in the axial direction D of the lid cover piece end portion 22e. This is the part 22. The maximum length in the height direction of the lid end piece 22e is determined so that at least the virtual straight line VE intersects the lid end piece 22e. Here, the virtual straight line VE passes through at least one of the cutting edges of the cutting blade 23 in the portion adjacent to the lid cover end portion 22e, and is inclined in a range between an angle parallel to the axial direction D and an angle parallel to the tip side 22t. Is a virtual straight line including a portion extending beyond the end of the cutting blade 23. In the example shown in FIG. 2A, the virtual straight line VE passes through two of the cutting edges of the cutting blade 23 in a portion adjacent to the lid cover piece end portion 22e and is parallel to the tip side 22t in a portion adjacent to the lid cover piece end portion 22e. It is a straight line. The cutting blade 23 is the end immediately after the length in the axial direction D enters the lid piece end portion 22e so that all the cutting edges come out from the tip side 22t. In the present embodiment, one ridge of the blade is in the lid end piece 22e. The front end side 22t of the lid cover end portion 22e has a gently curved arc shape (so-called R shape). Such an R shape makes it difficult to break because there is no bending point. Moreover, such an R shape can prevent the end of the cutting blade 23 from being unnecessarily hidden while increasing the average length of the lid cover piece end 22e in the height direction, and the cutting performance of the wrap film 91f. Can be suppressed. The distal end side 22t of the lid cover piece end portion 22e is generally aligned with the lower end of the side cover piece 25 at the outer end in the axial direction D. Typically, one side of the joining piece 22j continuing from the front end side 22t is substantially aligned with the lower side of the side lid piece 25 (see FIG. 1A). The wrap carton 1 is formed such that the average length in the height direction of the lid cover piece end portion 22e is longer than the average length in the height direction of the portion of the lid cover piece 22 adjacent to the inside thereof. Strength is improved than before. Further, in the wrap carton 1, one side of the joining piece 22 j continuing from the tip side 22 t is substantially aligned with the lower side of the side lid piece 25, so that the lower side of the side lid piece 25 is caught by something and the side lid piece 25 is It is possible to suppress turning and peeling from the joining piece 22j.

  Incidentally, unlike the conventional wrap carton shown in FIG. 2 (B), the length of the end portion of the lid cover piece 122 in the height direction is not long, and the tip side 122t formed in a V shape as a whole is formed. When extending linearly to the end portion, the height of the end portion in the axial direction D of the lid piece 122 is shortened. Then, when the wrap film is pulled out and cut with the cutting blade 23, the lid piece 122 may be distorted. In addition, when the height of the end portion in the axial direction D of the lid piece 122 is short and the tip side 122t of the end portion in the axial direction D is located above the lower side of the side lid piece 25, what is the lower side of the side lid piece 25? There is a possibility that the side cover piece 25 will turn over and peel off from the joining piece 22j. In the lap carton 1 shown in FIG. 2 (A), as described above, the probability of the inconvenience of the conventional wrap carton can be reduced.

  With reference to FIG. 3, the protrusion 15p provided on the side plate top side 17 will be described in detail. The left side view of FIG. 3 shows an open state. The protrusion 15p is formed in an elongated shape with the protrusion tip side 15ps, which is the tip side, extending along the side plate top side 17. In the present embodiment, the protrusion tip side 15 ps extends in parallel to the side plate top side 17. In this embodiment, the pair of sides connecting the projection tip side 15 ps and the side plate top side 17 of the projection 15 p are orthogonal to the projection tip side 15 ps and the side plate top side 17. On the other hand, the side on the front plate 12 side is away from the front plate 12 as it approaches the projection tip side 15 ps from the side plate top side 17 with respect to the projection tip side 15 ps and the side plate top side 17. It is diagonal. With such a configuration, the length of the protrusion tip side 15 ps is shorter than the length of the protrusion 15 p connected to the side plate top side 17. Further, the length of the protrusion tip side 15 ps is shorter than the width of the side plate 15 (hereinafter referred to as “side plate width 15 W”), and the protrusion tip side 15 ps is rear plate 14 than the center of the side plate width 15 W. It exists near. As a result, the end on the front plate 12 side of the protrusion tip side 15 ps is present away from the front plate 12 by a predetermined distance Sn. Here, the predetermined distance Sn is a length in a direction parallel to the direction in which the side plate top side 17 extends. The reason why the end of the protrusion tip side 15 ps is separated from the front plate 12 by the predetermined distance Sn is as follows.

  The protrusion 15p has a tip (protrusion tip side 15ps) facing the bottom plate 13 when the lid 20 is closed, but the tip is opposite to the bottom plate 13 by the joining piece 22j when the lid 20 is opened. It is bounced up to face. At this time, the protrusion 15p rotates with the side plate top side 17 as the rotation axis, and takes a locus in which the tip forms an arc. Therefore, the tip of the protrusion 15 p protrudes to the outside of the main body 10 most far from the side plate 15 on a virtual plane that passes through the side plate top side 17 and is orthogonal to the side plate 15. In the present embodiment, the protrusion tip side 15 ps and the side plate top edge 17 are parallel to each other, so that the entire protrusion tip side 15 ps protrudes to the outside of the main body 10 at an equal distance. At this time, as the projection 15p protrudes outward, the side lid piece 25 also bends outward. On the other hand, in the present embodiment, as described above, the tip side 22t (see FIG. 2A) of the lid cover piece end portion 22e approaches the bottom plate 13 side, and the end portion of the side cover piece 25 on the lid cover piece 22 side. Since it is connected to the lid lid piece 22 over the entire height, it is difficult to bend outward. On the other hand, the end portion of the side cover piece 25 opposite to the lid cover piece 22 has a room to bend outward. Therefore, in the present embodiment, when the lid portion 20 is opened and closed, the protrusion 15p is provided so that the protrusion tip side 15ps is present near the rear plate 14 where the side cover piece 25 is relatively easily bent outward, and the protrusion tip side 15ps. A predetermined distance Sn is separated from the end of the front plate 12 and the front plate 12. The force to bend the side lid piece 25 outward is generated when the projection tip side 15ps pushes the side lid piece 25, so that the side plate top side 17 of the projection 15p does not contact the side lid piece 25. The connecting portion may be relatively long so that the protrusion 15p is difficult to separate from the side plate top side 17. The predetermined distance Sn is preferably 10% or more of the side plate width 15W, more preferably 20% or more, from the viewpoint of smooth opening and closing of the lid portion 20. On the other hand, the predetermined distance Sn is preferably 60% or less of the side plate width 15W from the viewpoint of making the action of engagement between the projection tip side 15ps and the joining piece 22j when the lid portion 20 is closed. 40% or less is more preferable. In the present embodiment, the length of the protrusion tip side 15ps is about 50% of the side plate width 15W, and the predetermined distance Sn is about 30% of the side plate width 15W. In the present embodiment, the projection tip side 15ps and the rear plate 14 are also separated from each other on the rear plate 14 side (the projection 15p is also formed on the side plate top side 17 on the rear plate 14 side rather than the projection 15p). However, the protrusion 15p may be extended until it reaches the rear plate 14.

  Returning to FIG. 1 again, the description of the overall configuration of the lap carton 1 will be continued. In the wrap carton 1, 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.

  Here, the details of the flap 12f will be described with reference to FIG. 4 together with FIG. FIG. 4 is a front view of the wrap carton 1 and shows an open state. In the present embodiment, the flaps 12f are provided on both sides of the central region 12t along the front plate edge 19 so as to sandwich the central region 12t located at the center of the upper portion of the front plate 12. Here, the “central region 12t” is when the centroid of the lid cover piece 22 (the portion of the lid cover piece 22 near the top of the V-shaped tip side 22t) is pushed toward the front plate 12 with the lid portion 20 closed. Further, it is a portion of the front plate 12 with which the lid cover piece 22 contacts. At this time, the lap carton 1 having elasticity 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 12t. 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. A portion of the front plate 12 with which the lid cover piece 22 comes into contact when it is stopped by and stops moving to the rear plate 14 side is defined as a central region 12t.

  For the sake of convenience of explanation, two flaps 12f provided with the central region 12t interposed therebetween are shown as a left flap 12fA and a flap 12f on the right side of the central region 12t. 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 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 passes through the front plate 12 from the point 12cAN on the front plate edge 19 close to the central region 12t closer to the left side plate 15A than the central region 12t, and is 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 end side 19. The point 12cAN is positioned in the vicinity of the central region 12t 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 12t 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 central region 12t than the left end of the wrap film 91f. The left end of the left flap 12fA does not reach the left end of the wrap film 91f in a range that can be sandwiched between the flap 12fA and the lid piece 22, and this state is coincident with the left end of the wrap film 91f. It is assumed that the left flap 12fA extends substantially to the left end of the wrap film 91f, and the left flap 12fA has a left end outside the left end of the wrap film 91f. When the left end of the left flap 12fA is formed closer to the central region 12t 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, in the axial direction D, the left end of the left flap 12fA is formed 10 mm closer to the center region 12t than the left end of the front plate 12, and the left end of the left flap 12fA is located in the vicinity of the left end of the wrap film 91f. ing. By forming the left flap 12fA in this way, the width of the wrap film 91f is equal to the width of the wrap film 91f by the heel cover piece 22 that is less likely to be distorted because the average length in the height direction of the heel cover piece end 22e is increased. Substantially the end portion can be pinched, and slipping at the time of cutting the wrap film 91f can be suppressed. The maximum length in the height direction of the left flap 12fA is formed to be about ½ of the length in the height direction of the front plate 12. In the present embodiment, the lower side of the left flap 12fA is once again approached to the front plate edge side 19 after being slightly closer to the front side plate edge 19 when it is traced from the central region 12t 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 auxiliary plate (not shown) can be kept good. . When the left flap 12fA is excessively lifted from the surface of the front plate main body 12b (see FIG. 1A), the both ends of the cut line 12cA are slightly separated from the front plate end side 19 so that the left flap 12fA The floating condition can be adjusted. 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 upper limit of the distance between the end of the cut line 12cA and the front plate edge 19 is such that the left flap 12fA is the main body to the extent that the drawn long object 91f can be sandwiched between the full width of the left flap 12fA and the lid cover piece 22. It is preferable to determine within a range that opens to the outside of the portion 10, and it is assumed that both ends of the cut line 12 c </ i> A substantially reach the front plate edge 19. 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 a sub-plate (not shown) at the front plate edge 19. Further, the left flap 12fA is connected to the sub-plate (not shown) at the front plate end side 19 so that the front plate end side 19 can be rotated about the rotation axis. 12b (see FIG. 1A) is configured to float (project from the front plate body 12b).

  A stopper 50 as a locking means is formed on the surface of the left flap 12fA. 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 weakly attaches 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 away from the attachment surface, the wrap film 91f is easily peeled off. In the present embodiment, 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 shown in FIG. 4, there is a portion that is not formed intermittently within a range in which the wrap film 91f can be locked to such an extent that the wrap film 91f can be prevented from moving to the extent that hinders cutting. , Which means that there is a portion that is not formed at both ends. The stopper 50 can employ various modes useful for locking the wrap film 91f in addition to the mode shown in FIG. 1 and the mode shown in FIG. In the present embodiment, the stopper 50 is also formed on the surface of the front plate 12 outside the left flap 12fA.

  The right flap 12fB is formed symmetrically with the left flap 12fA about a virtual straight line 12v that bisects the front plate 12 into left and right. The points 12cBN and 12cBS of the right flap 12fB correspond to the points 12cAN and 12cAS of the left flap 12fA, respectively. In the present embodiment, the stopper 50 is also formed on the right flap 12fB over the entire length in the axial direction D, and the stopper 50 is also formed on the surface of the front plate 12 outside the right flap 12fB. Has been. Thus, the stopper 50 is formed substantially along the front plate edge 19 on the surface of each flap 12f. 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. Furthermore, in the present embodiment, the front plate edge 19 between the flap 12f and the side plate 15 (outside the flap 12f in the axial direction D) is also locked by means such as UV varnish application like the stopper 50. Is formed, and the occurrence of slipping of the wrap film 91f is further suppressed at the end in the width direction of the wrap film 91f that is relatively likely to slip when the wrap film 91f is cut.

  FIG. 5 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. 5, 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, which is not shown in FIG. 1, and 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 extend over the entire axial direction D. It is connected. 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. 5, side lid pieces 25 are connected to the lid 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.

  The operation of the wrapped carton 100 will be described with reference to FIGS. 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. 5) connected to the tip of the lid piece 22 via a perforation 29c (see FIG. 5) on the tip side 22t. The front plate 12 is bonded at a plurality of points. The wrapped carton 100 is displayed in a retail store in this state. In the present embodiment, as the average length in the height direction of the lid cover piece end portion 22e is increased, the area where the side cover piece 25 adheres to the joining piece 22j is relatively large. The lift of the piece 25 from the side plate 15 is suppressed, and the side lid piece 25 is hardly caught by something. When the wrap film 91f of the wrapping carton 100 in the consumer's hand is used for the first time, the cut piece 29 is cut off at the perforation 29c while being peeled off from the front plate 12, and separated from the lid cover piece 22. By opening the wrap carton 1 in this way, the lid 20 can be rotated around the rear plate edge 18 with respect to the main body 10. When the lid 20 is opened, the lid 20 can be opened by applying a force such that the projection 15p fitted in the recess 25d is detached from the recess 25d. In the present embodiment, the protrusion tip side 15 ps is provided closer to the rear plate 14 than the center of the side plate width 15 W, and the end of the protrusion tip side 15 ps on the front plate 12 side is predetermined with respect to the front plate 12. Since the distance Sn is present at a distance, even if the average length in the height direction of the lid cover piece end portion 22e is long and the end portion of the side cover piece 25 on the lid cover piece 22 side is difficult to bend outward, When the protrusion 15p is rotated by the movement of the joining piece 22j when the part 20 is opened and closed, an excessive resistance force does not act, and the opening and closing of the lid part 20 can be suppressed.

  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 using the wrap film 91f, 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.

  As described above, when the wrap film 91f is cut from the center of the width toward both ends by causing the cutting blade 23 corresponding to the V-shaped tip to bite into the center of the width of the wrap film 91f. Since the cutting blade 23 is formed in a double-folded polygonal line (since it is formed in a straight line from the center to the end), the wrap film 91f can be smoothly cut to the end of the width. When the wrap film 91f is cut in this way, a force in the direction in which the tip side 22t is separated from the front plate 12 acts on the lid piece 22 with the bent side 21f as the rotation axis. In the wrap carton 1 according to the present embodiment, the average length in the height direction of the lid cover piece end portion 22e is long, and therefore, when the wrap film 91f is cut, the lid cover piece 22 is in a direction away from the front plate 12. Even if the force acts on the lid portion 20, distortion of the lid portion 20 can be suppressed as compared with the conventional case.

  Further, when the wrap film 91f is pulled out and cut, the wrap film 91f is sandwiched between the flap 12f floating outward and the lid cover piece 22 of the closed lid portion 20 and formed along the front plate edge 19. Since the movement is restricted by the stopper 50, the stopper 50 is appropriately cut without sliding. In particular, in the wrap carton 1 according to the present embodiment, the flap 12f is divided into the left flap 12fA and the right flap 12fB and is provided independently on both sides of the central region 12t. When the centroid of the lid piece 22 is pushed, the flap 12f is hung and the sub-plate 16 (not shown in FIGS. 1 to 4 and not shown in FIG. 5) is prevented from sinking. For this reason, the drawn wrap film 91f is integrally extended from the vicinity of the center region 12t toward the side plate 15 to the substantially end of the width of the wrap film 91f, and the height of the lid end piece 22e. It can be firmly sandwiched between the lid cover piece 22 whose average length in the direction has become longer and is less likely to be distorted, and slipping during cutting of the wrap film 91f can be suppressed. 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.

  As described above, according to the wrap carton 1 and the wrapping carton 100 according to the present embodiment, the average length in the height direction of the heel cover piece end portion 22e is that of the portion of the heel cover piece 22 adjacent on the inside thereof. Since it is formed longer than the average length in the height direction, the strength of the lid 20 can be increased. Moreover, since the cutting blade 23 is formed in the shape of a folded line, the wrap film 91f can be smoothly cut to the end of the width. Moreover, since one side of the joining piece 22j continuing from the front end side 22t is substantially aligned with the lower side of the side lid piece 25, it is suppressed that the lower side of the side lid piece 25 is caught by something and the side lid piece 25 is turned up. can do.

  In the above description, the cutting blade 23 is V-shaped (bi-folded polygonal line shape), but may be a linear shape called a so-called flat blade. In this case, the tip side 22t of the lid cover piece 22 is linear (typically a straight line parallel to the bent side 21f) except for the lid cover end 22e. Increasing the length of the lid end piece 22e in the height direction is particularly useful when a V-shaped cutting blade 23 is used, which tends to shorten the length of the lid end piece 22e in the height direction. Even if it is applied when the cutting blade 23 is linear, it contributes to the reinforcement of the lid 20 and is useful. In particular, when the linear cutting blade 23 is used and the length in the height direction of the lid piece 22 is relatively short over the entire axial direction D, the length in the height direction of the lid piece end 22e. It is useful to lengthen the length. In addition, when the cutting blade 23 is formed in a linear shape, when cutting the drawn wrap film 91f, the wrap film 91f is generally cut from one end of the width of the wrap film 91f to the other end. It becomes. Even in the case where the cutting blade 23 is formed in a V shape (a folded line shape), the wrap film 91f can be cut from one end to the other end of the width of the wrap film 91f. In addition to the V-shaped (bi-folded polygonal line) and flat blades, the cutting blade 23 is formed in a V-shaped (bi-folded polygonal line) central portion in the axial direction D, and the outer side thereof is the axial direction. D may be formed parallel to D. Regardless of the shape of the cutting blade 23, when the wrap film 91f is cut from one end of its width to the other end, if the length of the lid end piece 22e in the height direction is long, the lid Since the part 20 becomes difficult to be distorted, the cut property is improved.

  In the above description, the cutting blade 23 is attached to the lid piece 22 so that all the cutting edges come out from the tip side 22t even at the end in the axial direction D. However, the end in the axial direction D is the lid. You may extend in the axial direction D so that it may be covered by the one end part 22e. In this case as well, the virtual straight line VE does not change from the lid cover end portion 22e. When the end in the axial direction D of the cutting blade 23 is covered with the lid end piece 22e, the joining area between the cutting blade 23 and the lid cover piece 22 can be increased, and the joining between the cutting blade 23 and the lid cover piece 22 is achieved. Strength can be improved. On the other hand, if the length of the cutting blade 23 is such that all the cutting edges come out from the tip side 22t even at the end in the axial direction D, the amount of the cutting blade 23 used can be suppressed.

  In the above description, the front plate 12 as the side on the front plate 12 side of the pair of sides connecting the projection tip side 15 ps and the side plate top side 17 approaches the projection tip side 15 ps from the side plate top side 17. However, it may be perpendicular to the protrusion tip side 15 ps and the side plate top side 17. However, from the viewpoint of making it difficult to separate the protrusion 15p from the side plate top side 17, the locking function by the projection 15p is made from the viewpoint of smoothing the opening and closing of the lid portion 20 while lengthening the portion where the projection 15p connects to the side plate top side 17. In order to increase the predetermined distance Sn within a range in which the protrusion 15p can be secured, the length of the protrusion tip side 15ps is preferably shorter than the length of the protrusion 15p connected to the side plate top side 17.

  In the above description, the projection tip side 15 ps is parallel to the side plate top side 17. However, the deflection of the side cover piece 25 when the projection 15 p protrudes outward on the front plate 12 side. It may be formed so that it may become the outline along. For example, the protrusion tip side 15ps may be formed in a gently curved shape so that the distance between the protrusion tip side 15ps and the side plate top side 17 becomes shorter toward the front plate 12 side. . However, from the viewpoint of securing the lock function by the protrusion 15p when the lid portion 20 is closed, it is preferable that the protrusion tip side 15ps is parallel to the side plate top side 17.

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