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 the fitting of a flap.

  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). ).

JP 2008-239252 A (FIGS. 3 and 8, etc.)

  However, the flap formed by cutting the top of the box front wall fits into the box front wall when it is flush with the box front wall, such as when the lid is closed, Even when the lid is opened, the expected function may not be exhibited without being separated from the front wall of the box.

  In view of the above problems, an object of the present invention is to provide a wound body storage box and a storage box containing a wound body that prevent the fitting of a flap.

  To achieve the above object, the wound body storage box according to the first aspect of the present invention houses a wound body 91r around which a long object 91f is wound, for example, as shown in FIG. It is the main-body part 10 formed in the rectangular parallelepiped shape, Comprising: It forms in the opening surface 10h which one of four rectangular surfaces parallel to the axis 91a of the winding body 91r opened when the winding body 91r was accommodated. In addition, the front plate 12 that constitutes one of the two rectangular surfaces orthogonal to the opening surface 10h, and the front plate 12 at the front plate edge 19 that is the edge that intersects the opening surface 10h of the front plate 12 A main body 10 having a sub-plate 16 (see, for example, FIG. 1B) that is in contact with the front plate 12 inside the main body 10 while being connected to each other is provided; the front plate 12 extends in the plane of the front plate 12 By cutting along the cut line 12c that passes therethrough, the front plate edge 19 is set as the rotation axis. The cut line 12c is formed so that both ends thereof reach the sub plate 16 from the front plate 12 over the front plate edge 19 (for example, FIG. 1 (). B))); the distance between the cut lines 12c in the axial direction D increases as the score line 12c (see FIG. 1A) formed in the sub-plate 16 moves away from the front plate edge 19; It extends with an angle with respect to the direction orthogonal to the front plate edge 19 so as to be wide, and is located outside the projected flap 12f when the flap 12f is projected onto the sub-plate 16 (for example, 2 (A)); the length of the component in the direction perpendicular to the front plate edge 19 of the cut line 12c formed in the sub-plate 16 is 6 mm or less.

If comprised in this way, since the cut line has reached the sub board across the front board edge from the front board, the part of the flap adjacent to the cut line which has reached the sub board floats from the sub board It becomes a tendency and the fitting of the flap to the part of the front plate (front plate main body) other than the flap can be prevented from the relevant part as a starting point. Moreover, since the length of the component in the direction orthogonal to the front plate edge of the score line formed in the sub plate is 6 mm or less, it is possible to avoid bending the sub plate in the portion facing the flap. And by extension, a decrease in strength can be suppressed.
Moreover, if comprised in this way, it can prevent that the subplate of the part which opposes the flap of the part between the edge part of a score line, and the front-plate end side protrudes outside a main-body part, and opposes a flap. It can avoid more reliably that the subplate of the part to be bent will be bent.
Moreover, if comprised in this way, the both ends of a flap will tend to float from a subplate, and it can prevent the fitting to the front plate main body of a flap more reliably.

  Further, the wound body storage box according to the second aspect of the present invention is, for example, as shown in FIG. 2A, in the wound body storage box according to the first aspect of the present invention, the front plate end side. The length 12W between both ends of the cut line 12c in the component in the direction D parallel to 19 is formed to be 1/5 or more of the length of the front plate edge 19.

  If comprised in this way, it can suppress that the subplate of the part facing a flap will bend.

  Moreover, the wound body storage box 1 according to the third aspect of the present invention is, for example, as shown in FIG. 1A, the wound body storage box 1 according to the first aspect or the second aspect of the present invention. The flap 12f includes a first flap 12fA and a second flap 12fB provided at an interval from the first flap 12fA.

  If comprised in this way, the probability which will be in the state which does not have the flap which floated from the sub-plate at all can be reduced.

  Moreover, the wound body storage box which concerns on the 4th aspect of this invention is a wound body which concerns on any one aspect of the said 1st aspect thru | or 3rd aspect of this invention, as shown, for example in FIG. In the storage box, the front plate 12 is configured such that a step S is formed between the front plate end side 19A of the flap 12f portion and the front plate end side 19 of the portion 12b other than the flap 12f.

  If comprised in this way, fitting to the front-plate main body of a flap can be prevented further more reliably.

  A container with a wound body according to the fifth aspect of the present invention includes, for example, a wound body 91r around which a thin film-like long object 91f is wound, as shown in FIG. The wound body storage box 1 according to any one of the first to fourth aspects is provided.

  If comprised in this way, it will become a storage box containing a winding body which can prevent the fitting of the flap to a front board main body, suppressing the fall of intensity | strength.

  According to the present invention, the portion of the flap adjacent to the cut line reaching the sub plate tends to float from the sub plate, and the flap is fitted to the front plate portion other than the flap starting from the portion. Can be prevented.

(A) is the fragmentary front view which looked at the sub-plate of the lap carton concerning the embodiment of the present invention from the inside, and (B) is the partial side sectional view of the wrap carton concerning the embodiment of the present invention. It is an expanded view of the lap carton which concerns on embodiment of this invention. It is a partial front view which shows the circumference of the flap of the wrap carton which concerns on the modification of embodiment of this invention.

  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 surface 10h of the main body portion 10, and the lid cover 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 cut 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. For the convenience of explanation, the two flaps 12f are referred to as a left flap 12fA and a right flap 12f as a right flap 12fB when viewed from the front (when viewed from the front plate 12). To do. 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. Both the left flap 12fA and the right flap 12fB are 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.

  When the left flap 12fA is viewed facing the front plate 12, a cut line 12cA formed in the surface of the front plate 12 and a front plate end side 19 are contoured. The cut line 12cA is a line that mainly cuts 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 when viewed in front of the front plate 12, and from the point on the front plate edge 19 from the surface of the front plate 12 It is formed by cutting the in-plane of the front plate 12 so as to reach the point on the front plate edge 19 close to the left side plate 15A. Both ends of the cut line 12cA are separated from each other in the axial direction D, and are both hung on the front plate edge 19. 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 end side 19 once again when it is traced from the center in the axial direction D of the front plate 12 to the left side plate 15A side. It is formed in a smooth curve that separates from the plate edge 19. In other words, the center portion of the left flap 12fA is slightly recessed above both ends.

  As shown in the partial front view of the auxiliary plate 16 of the lap carton 1 shown in FIG. 2A viewed from the inside, the cut line 12 c extends to the auxiliary plate 16. The cut line 12c formed in the sub plate 16 extends from the front plate 12 (see FIG. 1A) beyond the front plate end side 19. In the present embodiment, both ends of the cut line 12 c reach the sub plate 16. The length of the component in the direction perpendicular to the front plate edge 19 (hereinafter referred to as “orthogonal component length H”) of the score line 12c formed in the sub plate 16 is 6 mm or less. By being comprised in this way, it can prevent that the subplate 16 bends with the straight line which ties the both ends of the cut line 12c, and is trying to suppress the fall of the intensity | strength of the lap carton 1. FIG. Further, the cut line 12c formed in the sub-plate 16 is formed on the front plate end side 19 so that the distance between both the cut lines 12c in the axial direction D increases as the distance from the front plate end side 19 increases. It extends at an angle with respect to the orthogonal direction. In other words, when the flap 12f is projected onto the sub-plate 16 that is in contact with the front plate 12 at the surface, the flap 12f projected on the sub-plate 16 (shown by a broken line in FIG. 2A) is outside the flap 12f. The cut line 12c formed in the sub plate 16 is located. By being configured in this way, the sub-plate 16 at a portion between the straight line connecting both ends of the cut line 12c and the front plate end side protrudes to the outside of the main body portion 10 (see FIG. 1A). Even if it does so, it will be prevented by the front-plate main body 12b, and it will contribute to the difficulty of the bending of the subplate 16 in the straight line which ties the both ends of the cut line 12c.

  Further, the length between both ends of the cut line 12c in the component in the axial direction D (hereinafter referred to as “length between both ends 12W”) is the length of the front plate end side 19 (the left side plate 15A and the right side plate). It is preferable that it is 1/5 or more of the length (between 15B) because it contributes to the difficulty of bending the sub-plate 16 at the straight line connecting both ends of the cut line 12c. In the present embodiment, the orthogonal component length H is 2.5 mm, and the length 12W between both ends is 120 mm (about 2/5 of the front plate edge 19). In addition, the orthogonal component length H of the cut line 12c in the surface of the sub-plate 16 is preferably 1 mm or more from the viewpoint of suppressing the fitting of the flap 12f to the front plate body 12b. From the viewpoint of preventing the sub-plate 16 from being bent along a straight line connecting both ends, it is preferably 4 mm or less, and more preferably 3 mm or less.

  With reference to FIG. 1 again, the description of the configuration of the wrap carton 1 will be continued. When viewed from the front plate 12, the both ends of the cut line 12cA constituting the outline of the left flap 12fA are the front plate ends. By reaching the side 19, a considerable amount of the left flap 12fA can be lifted from the sub plate 16 (from the surface of the front plate main body 12b). The left flap 12fA 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 by the cut line 12cA. Further, if the length 12W between both ends (see FIG. 2A) is 1/5 or more of the length of the front plate edge 19, it is possible to prevent the left flap 12fA from being cut off and dropped. This is preferable because a distance for connecting the left flap 12fA and the sub-plate 16 can be secured. Further, since the left flap 12fA is connected to the sub plate 16 at the front plate end side 19, the left flap 12fA can rotate about the front plate end side 19 as a rotation axis, and is lifted 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).

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

  The right flap 12fB provided in line symmetry with the left flap 12fA has a cut line 12cB formed in the plane of the front plate 12 and the front plate edge 19 when viewed in front of the front plate 12. Is the outline. When the cut line 12cA and the cut line 12cB are not distinguished (typically when the generically described flap 12f is described), they are simply referred to as “cut line 12c”. Also on the right flap 12fB, the stopper 50 is formed in a line-symmetric manner with respect to the left flap 12fA. The stopper 50 is provided on the front plate edge 19 between the left flap 12fA and the right flap 12fB, between the left flap 12fA and the left side plate 15A, and between the right flap 12fB and the right side plate 15B. Are formed along.

  As shown in FIGS. 1B and 2A, the sub plate 16 includes a cut piece 16f. The cut piece 16f is formed by cutting the surface of the sub-plate 16 along the cut line 16c. In the present embodiment, as shown in FIG. 1B, two cutout pieces 16f are provided. Regarding the two cut pieces 16f provided, for convenience of explanation, the cut piece 16f on the back side of the left flap 12fA is called the left cut piece 16fA, and the cut piece 16f on the back side of the right flap 12fB is called the right cut piece 16fB. I will do it. When a configuration common to the left cut piece 16fA and the right cut piece 16fB is described, it is simply referred to as “cut piece 16f”. In the present embodiment, the cut piece 16f is provided at a position included in the flap 12f when projected onto the front plate 12. The sub plate 16 is bonded to the front plate 12 below the bottom point of the flap 12f (on the bottom plate 13 side). In other words, the flap 12f is not bonded to the sub-plate 16, and the cut piece 16f is not bonded to the front plate 12. By being configured in this way, the flap 12f cut by the cut line 12c can float from the sub plate 16, and the cut piece 16f cut by the cut line 16c can be removed from the other sub plate 16. Can protrude. With the above-described configuration, as shown in FIG. 2B, the flap 12f floats outside, and the cutout piece 16f floats inside.

  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, 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. 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. In the wrap carton 1, a pair of left and right cut pieces 16 f that protrudes inward of the main body 10 with the front plate edge 19 as a rotation axis are provided, so that when the wrap film 91 f is pulled out, the main body 10 The accommodated lap roll 91r is suppressed by the cut piece 16f, and the wrap roll 91r can be prevented from jumping out of the main body portion 10. 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 floats outside the main body portion 10, so that the wrap film 91f attached to the stopper 50 formed on the flap 12f The tip also floats from the front plate body 12b and is easy to pick. In the present embodiment, since the score line 12c reaches the sub plate 16 from the front plate 12 beyond the front plate end side 19, it reaches the front plate end side 19 of the sub plate 16 at the length 12W between both ends. The adjacent portion can be shifted to the inside or outside of the main body 10 with respect to the surface of the other portion of the sub-plate 16, and the portion of the flap 12 f adjacent to the cut line 12 c floats from the sub-plate 16. It tends to leave. Thereby, even when the lid portion 20 is closed and the lid cover piece 22 is pushed toward the front plate 12, the flap 12f can be prevented from fitting into the front plate body 12b, and is placed on the flap 12f. It can be avoided that the leading end of the wrap film 91f is not lifted from the front plate body 12b and becomes difficult to pick. Further, in the wrap carton 1, since the flap 12f is not formed between the left flap 12fA and the right flap 12fB, the wrap film 91f can be easily picked by putting a finger into this gap.

  Further, from the viewpoint of increasing the strength of the wrap carton 1, if the wrap carton 1 is made of a relatively hard paperboard, if the cut line 12c does not reach the subboard 16, the paperboard is bent 180 degrees. In the vicinity of the front plate edge 19 adjacent to the front plate body 12b (the front plate edge 19 between the two flaps 12f), the paperboard is bent out of a predetermined position (position where the folding is planned). The surface portion of the bent portion may break. In the present embodiment, even if it is bent and deviated from a predetermined position in the vicinity of the front plate edge 19 adjacent to the flap 12f, it reaches the sub-plate 16 from the front plate 12 over the front plate edge 19. Since the edge of the bent folding line can be cut by the cut line 12c, the front plate edge 19 between the two flaps 12f can be bent at a predetermined position, and the surface layer portion is broken. Can be suppressed.

  As described above, according to the wrapped carton 100 according to the present embodiment, the cut line 12c reaches the sub-plate 16 from the front plate 12 across the front plate end side 19, and thus the flap. 12f can be prevented from fitting into the front plate main body 12b, and the ease of picking the wrap film 91f can be ensured.

  As shown in FIG. 4, the front plate edge 19A of the flap 12f portion of the front plate 12 is formed above the front plate edge 19 of the front plate body 12b, and the front plate edge of the flap 12f portion is formed. A step S may be formed between the side 19A and the front plate end side 19 of the front plate body 12b. With this configuration, when the flap 12f is closed so as to be in contact with the sub plate 16 at the surface, a gap is formed between the flap 12f and the front plate body 12b, and the flap to the front plate body 12b is formed. The fitting of 12f can be prevented more reliably.

  Or although illustration is abbreviate | omitted, the front-plate edge 19A of the flap 12f part of the front board 12 is formed below the front-plate edge 19 of the front-plate main body 12b, and the front-plate edge of the flap 12f part You may comprise so that a level | step difference may be formed between 19A and the front-plate edge 19 of the front-plate main body 12b. When configured in this manner, when the flap 12f is closed so as to be in contact with the sub-plate 16, the part of the flap 12f (the portion along the lower side) overlaps the front plate body 12b. The fitting of the flap 12f into the front plate body 12b can be prevented more reliably.

  In the above description, both ends of the cut line 12c have reached the sub plate 16, but one end of the cut line 12c has reached the sub plate 16 and the other end. The configuration may be such that the portion does not reach the sub plate 16 and is stopped at the front plate end side 19. In this case, in the wrapping carton 100 in which the cutting blade 23 is formed in a V shape, taking the central portion in the width direction of the wrap film 91f contributes to the convenience, the flap 12f in the central portion in the axial direction D is used. From the viewpoint of preferentially preventing the front plate body 12b from being fitted, the end closer to the center in the axial direction D of both ends of the cut line 12c reaches the sub plate 16. Is preferred.

  In the above description, the cut line 12c formed in the sub-plate 16 extends so that the distance between the two cut lines 12c in the axial direction D increases as the distance from the front plate edge 19 increases. However, the distance between the two cut lines 12c in the axial direction D increases as the distance from the front plate edge 19 increases, for example, in a direction orthogonal to the front plate edge 19. You may be comprised so that it may extend.

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

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