In a front plate 12 of the body part 10, a locking means 50 locking the long article is formed in a covered region W covered when the lid part is closed. The covered region W is divided into major regions M having three regions M1, M2, M3 and a central region C. The locking means 50 is constituted so that an area of a portion of the first region M1 surrounded by an outer edge including a gap 51g is larger than the area of each of the second region M2 and the third region M3 and the maximum height of the locking means 50 in the first region M1 is equal to or more than 1/2 of the maximum height of the first region M1 itself. Accordingly, when peeling the long article from the locking means 50 upon drawing the long article by picking up a width central part, locking force in edge parts where tension of a longitudinal direction component becomes large becomes relatively small. Accordingly, the long article is prevented from being damaged.

Description

  The present invention relates to a wound body storage box and a storage box with a wound body, and particularly relates to a wound body storage box and a storage body with a wound body capable of suppressing damage to a long object drawn from the wound body.

  Food wrap films that wrap food, dishes, or dishes such as dishes with each dish are widely used. A food plastic wrap film is typically a long plastic film (rolled body) wound in a roll, and is contained in a long rectangular parallelepiped container (container box). The required amount of film is pulled out of the roll and cut with a cutting blade attached to the lid of the container. In order to prevent the cut end of the drawn film from rolling back into the container, a part that is covered with a cover plate on the upper front outer side of the container is provided with a temporary fixing part for locking the film after cutting There is. Furthermore, as a wrap film storage box that has been improved so that the shape of the side edge of the cut film is aligned in a straight line while preventing the drop in cutting performance when cutting the drawn film from its side edge, a temporary fastening portion is provided. It is arranged at a position from the position 3 to 6 mm away from the upper edge of the front plate to the cutting edge of the cutting tool at the tip of the lid piece, and the shape of the band extends to the full length of the box, and the band Two notches having a width corresponding to about 1/2 to 3/4 of the width of the belt body and a corresponding length in the longitudinal direction are provided at three locations, the longitudinal center portion and both longitudinal end portions, and the resulting two protrusions Some parts are arranged so that the butt part is formed toward the bottom plate side of the box (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 7-33139 (paragraph 0009, FIGS. 1 and 2 etc.)

  However, the wrapping film storage box described in the above-mentioned Patent Document 1 has a length of the notch in the longitudinal center of the belt body that is longer than the length of the notches in both longitudinal ends. When peeling the film temporarily fixed from the formed front plate, if you try to peel it off by grabbing the center of the width of the film, the film part that is locked to the two protrusions with strong adhesion The component force in the longitudinal direction of the working tension increases, and the film may be torn.

  An object of this invention is to provide the wound body storage box and the storage box containing a wound body which can suppress damage to a long thing in view of the above-mentioned subject.

  In order to achieve the above object, the wound body storage box according to the first aspect of the present invention is a winding around which a long object 91f is wound, as shown in FIGS. 1, 2 and 5B, for example. The main body 10 that accommodates the winding body 91r is formed with an opening through which the long object 91f can be pulled out when the winding body 91r is housed, and the opening surface 10h that is the surface on which the opening is formed. The main body 10 intersects the rear plate 14 intersecting, the front plate 12 formed in a flat plate shape facing the rear plate 14 and intersecting the opening surface, the opening surface 10h, the rear plate 14 and the front plate 12. A main body 10 having a pair of side plates 15 constituting the end surfaces of the rear plate; and a lid portion 20 rotatably connected to a rear plate end side 18 which is an end side intersecting the opening surface 10h of the rear plate 14. When the lid portion 20 is closed, the lid plate 21 that covers the opening surface 10h and the lid connected to the lid plate 21 A lid portion 20 having a lid cover piece 22 that covers a part of the front plate 12 along a front plate edge 19 that is a piece 22 and an edge that intersects the opening surface 10h of the front plate 12; 12, the locking means 50 that locks the long object 91f substantially at a predetermined position in a covering region W (see FIG. 2) that is a region covered with the lid cover piece 22 when the lid 20 is closed. The covering region W is formed in the longitudinal direction D, which is a direction parallel to the front plate edge 19, and the center in the longitudinal direction D of the lid piece 22 with the lid 20 closed. Center region C in a predetermined range with reference to the range where the lid piece 22 and the front plate 12 are in contact with each other when the portion is pushed toward the front plate 12, and the main region M on the side plate 15 side of the central region C. The main region M is further divided into three equal parts in the longitudinal direction D and the side plate 15 from the central region C side. In order toward the first region M1, the second region M2, and the third region M3; a first locking region Q1 that is a portion surrounded by the outer edge of the locking means 50 in the first region M1 (FIG. 5 (B)) is an area of the second locking region Q2 (see FIG. 5 (B)), which is a portion surrounded by the outer edge of the locking means 50 in the second region M2, and in the third region M3. In a height direction that is larger than the area of the third locking region Q3 (see FIG. 5B) that is a portion surrounded by the outer edge of the locking means 50 and that is perpendicular to the front plate edge 19. When viewed, the maximum distance HQ1 in the height direction of the first locking region Q1 (see FIG. 5B) is the maximum distance HM1 in the height direction of the first region M1 (see FIG. 5B). It is formed in half or more. Here, “the outer edge of the locking means” refers to the outline of the locking means as a whole by replenishing the gap even if there is a gap where the locking means is not partially formed. This is the boundary where Further, typically, the main body is formed in a rectangular parallelepiped shape, and the opening surface is one of four rectangular surfaces that are parallel to the axis of the wound body when the wound body is accommodated in the main body. The rear plate forms one of two rectangular surfaces orthogonal to the opening surface, the front plate forms a rectangular surface facing the rear plate, and the pair of side plates are perpendicular to the four rectangular surfaces. A rectangular parallelepiped end face is formed.

  With this configuration, when the long object is peeled off from the locking means when the long object is pulled out from the wound body by picking the central part in the longitudinal direction (width direction of the long object), the tension in the longitudinal direction is reduced. Since the locking force at the end in the longitudinal direction of the long object that becomes large is relatively small, damage to the long object is suppressed.

  In addition, the wound body storage box according to the second aspect of the present invention is, for example, as shown in FIG. 3, in the wound body storage box according to the first aspect of the present invention, the first region M1 (for example, FIG. 2) is formed by intermittently opening a plurality of gaps 51g where the locking means 50 extending in the direction intersecting the longitudinal direction D is not formed.

  If comprised in this way, the difficulty of pulling out will be suppressed more.

  Moreover, the wound body storage box 1 according to the third aspect of the present invention is, for example, as shown in FIGS. 1 and 2, the wound body storage box 1 according to the first aspect or the second aspect of the present invention. The front plate 12 includes a flap 12f that can sandwich the long object 91f drawn from the wound body 91r with the lid cover piece 22 when the lid 20 is closed. Typically, the front plate 12 has a flap 12 f in the covering region W, and the flap 12 f extends along the front plate edge 19. Moreover, the winding body storage box which concerns on the 4th aspect of this invention is the winding body storage box 1 which concerns on the said 3rd aspect of this invention, for example, as shown in FIG.1 and FIG.2. The first flap 12fA provided to be included in the main region M between the first side plate 15A and the central region C, which is one of the pair of side plates 15, and the first side plate 15A A second flap 12fB provided in a main region M between the opposing second side plate 15B and the central region C; and the first flap 12fA is formed in the central region C. The second flap 12fB is formed so as to extend integrally from the vicinity toward the first side plate 15A and substantially to the end of the width of the long object 91f; Formed integrally extending to the edge of the long object 91f toward the plate 15B. It has been.

  If comprised in this way, the latching by the latching means of the elongate object pulled out can be performed more effectively.

  Moreover, the wound body storage box which concerns on the 5th aspect of this invention is a wound body which concerns on any one aspect of the said 1st aspect thru | or 4th aspect of this invention, as shown, for example in FIG. In the storage box 1, the lid piece 22 is connected to the lid plate 21 via a linear bent side 21 f, and the leading end side 22 t facing the bent side 21 f extends from the midpoint of the leading end side 22 t to the leading end side. The distance between the bent side 21f and the front end side 22t in the direction orthogonal to the bent side 21f is shortened as it moves toward the end of 22t.

  With this configuration, when a long object is cut from the center in the longitudinal direction toward both ends, the long object immediately after cutting near the center is effectively locked by the locking means. It becomes easy to cut by suppressing the generation of wrinkles on the scale.

  Moreover, the wound body storage box which concerns on the 6th aspect of this invention is any one of the said 1st aspect thru | or 5th aspect of this invention, as shown, for example in FIG.2 and FIG.5 (B). In the wound body storage box according to the aspect, the locking means 50 is formed in the main region M over substantially the entire longitudinal direction D when viewed in the longitudinal direction D, and when viewed in the height direction. The average distance in the height direction of the third locking region Q3 is less than 0.7 times the maximum distance in the height direction of the first locking region Q1. Here, the “average distance in the height direction” is synonymous with the average value of the distance in the height direction.

  If comprised in this way, damage to a long thing will be suppressed more and it will become easier to cut | disconnect.

  Moreover, the container-containing storage box according to the seventh aspect of the present invention includes, for example, as shown in FIG. 1, a wound body 91r around which a thin thin film 91f is wound; The winding body storage box 1 which concerns on any one aspect of the aspect thru | or a 6th aspect is provided.

  With such a configuration, the winding that can suppress damage to the long object when the long object is peeled from the locking means when the long object is pulled out from the wound body by pulling the center in the longitudinal direction. It becomes a containing box.

  According to the present invention, when the long object is peeled from the locking means when the long object is picked from the center in the longitudinal direction and pulled out from the winding body, the longitudinal direction of the long object increases in the longitudinal direction. Since the locking force at the end portion of the frame is relatively small, damage to the long object is suppressed.

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

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

  The main body 10 is a box in which one of the elongated surfaces is an opening surface 10h with respect to a rectangular parallelepiped having a size capable of accommodating an unused wrap roll 91r. The size of the main body 10 is formed as small as possible while a gap that does not prevent the accommodated unused lap roll 91r from rotating around the axis 91a is formed. In the present embodiment, the width is 44 mm, It has a size of 44 mm in height and 310 mm in length. The 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 substantially the same size as the front plate 12 but is not in contact with the bottom plate 13 and is provided inside the main body 10 with respect to the front plate 12. The sub-plate 16 is bonded to the front plate 12 at the end on the bottom plate 13 side along the longitudinal direction.

  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 lid plate 21 has one side in the longitudinal direction 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 (length in the short side direction of the rectangular front plate 12) at both ends in the direction in which the axis 91a of the wrap roll 91r extends (hereinafter referred to as “axis direction D”) is short of the front plate 12. About 1/2 of the length in the side direction and the height of the central portion in the axial direction D is about 3/4 of the length in the short side direction of the front plate 12. As the front end side 22t facing the bent side 21f moves from the center in the axial direction D to each end, the distance between the bent side 21f and the front end side 22t in the direction orthogonal to the axial direction D decreases. It is formed to become. With such a configuration, the tip side 22t facing the bent side 21f is formed in a V shape. When the lid portion 20 is closed, the lid cover piece 22 overlaps the outside of the front plate 12 along the front plate 12 and covers the upper portion of the front plate 12 in a pentagonal shape. The lid piece 22 is configured such that the length in the axial direction D is slightly longer than that of the front plate 12 and is longer than the width of the wrap 91 accommodated in the main body 10. Thereby, the lid cover piece 22 is comprised so that the lap | wrap film 91f pulled out from the inside of the main-body part 10 can be pinched | interposed between the front plates 12 over the whole width. A cutting blade 23 for cutting the wrap film 91f is attached to the distal end side 22t of the lid piece 22. The cutting blade 23 is provided in a V shape along the tip side 22t so that the cutting edge comes out of the tip side 22t.

  The side lid piece 25 is provided orthogonal to both the lid plate 21 and the lid lid piece 22. A total of two side lid pieces 25 are provided at both ends of the lid plate 21 (the lid lid piece 22). The basic shape of the side cover piece 25 is such that the long side is the same length as the short side of the cover plate 21, and the short side is the height at the center of the lid piece 22 (from the V-shaped tip to the bent side 21f). It is formed in a rectangle having the same length as the shortest distance. The side cover piece 25 is fixed to the joining piece 22j connected to the lid cover piece 22 with an adhesive. A recess 25 d is formed on the inner side of the side lid piece 25 between the joining piece 22 j and the lid plate 21. When the lid portion 20 is closed, a protrusion 15p provided on the upper end of the side plate 15 is fitted into the recess 25d. When the lid portion 20 configured as described above is closed, the lid portion 20 covers the opening 10h of the main body portion 10, and the lid lid piece 22 covers the upper portion of the front plate 12.

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

  Here, the details of the flap 12f will be described with reference to FIG. 2 together with FIG. FIG. 2 is a front view of the main body 10 of the lap carton 1. In the present embodiment, the flap 12f is located outside the central region C along the front plate edge 19 so as to sandwich the central region C located in the center in the longitudinal direction of the front plate 12 (the same direction as the axial direction D). Is provided. The “central region C” is defined as follows. A portion of the front plate 12 that is covered with the lid piece 22 when the lid 20 is closed is referred to as a “covering region W”. In FIG. 2, a portion surrounded by a virtual boundary line 12 b indicated by a two-dot chain line, a front plate end side 19, and both side plates 15 is a covered region W. The covering region W is divided into three in the longitudinal direction (axial direction D) of the front plate 12, and the middle region is defined as a central region C and both sides thereof as “main regions M”. In other words, two main regions M are formed so as to sandwich the central region C therebetween. The width (longitudinal distance) of the central region C is such that the centroid of the lid cover piece 22 (the portion of the lid cover piece 22 near the V-shaped apex of the tip side 22t) faces the front plate 12 with the lid 20 closed. When pressed, the distance is an arbitrary value within a range of ± 20% with reference to the distance in the range where the lid cover piece 22 contacts. For example, when the centroid of the lid cover piece 22 is pushed toward the front plate 12 with the lid portion 20 closed, if the range where the lid cover piece 22 contacts the front plate 12 is 40 mm, the width of the central region C is It can be arbitrarily determined between 32 mm and 48 mm. At this time, the elastic wrap carton 1 can change the range in which the lid cover piece 22 and the front plate 12 are in contact with each other depending on the magnitude of the force pushing the lid cover piece 22 toward the front plate 12, but defines the central region C. In doing so, when the centroid of the lid piece 22 is pushed toward the front plate 12 with the unused wrap roll 91r accommodated in the main body 10, the front plate 12 is in the wrap roll 91r in the main body 10. The distance in the longitudinal direction of the range in which the lid cover piece 22 and the front plate 12 are in contact with each other when it stops and is no longer moved toward the rear plate 14 is used as a reference for defining the width of the central region C. In the present embodiment, the width of the central region C is defined as 40 mm and is approximately 13% of the width of the front plate 12 (distance in the longitudinal direction), but the width of the central region C is 20 mm to 70 mm, preferably 30 mm. It may be determined in a range of ˜50 mm, or 6% to 25%, preferably 10% to 16% of the width (distance in the longitudinal direction) of the front plate 12.

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

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

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

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

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

  The predetermined position where the stopper 50 is formed in the height direction differs depending on the area. For convenience of explanation of this difference, each main region M is further divided into three equal parts in the axial direction D, and the first region M1, the second region M2, It shall be partitioned from the third region M3. The sections of the first region M1, the second region M2, and the third region M3 are formed symmetrically about an imaginary straight line 12v that bisects the front plate 12 to the left and right. Note that the covering region W, the central region C, the main region M, the first region M1, the second region M2, and the third region M3 are virtually divided for convenience of explanation, and each boundary line is actually It does not matter whether it appears on the front plate 12 or not. In the present embodiment, in the height direction, the maximum distance of the stopper 50 is the largest in the first region M1, and decreases in the order of the second region M2 and the third region M3.

  The stopper 50 will be described in more detail. In the present embodiment, as the basic shape of the lower contour advances from the boundary between the central region C and the first region M1 toward the left side plate 15A, the stopper 50 After the distance in the height direction (hereinafter sometimes simply referred to as “height”) is gradually increased, the distance reaches the maximum at a position advanced about 2/3 of the length in the axial direction D of the first region M1. From there, the end of the left flap 12fA is gradually decreased from the position where the length in the axial direction D of the second region M2 is about 1/3 from the boundary between the first region M1 and the second region M2. Up to approximately the same height. An overview of the shape of the stopper 50 is a downwardly convex arc shape near the central region C, and an elongated strip shape near the left side plate 15A.

  In the present embodiment, the maximum distance of the stopper 50 in the height direction is substantially the maximum distance of the first region M1 in the height direction (the height of the boundary line between the first region M1 and the central region C). The height of the belt-like stopper 50 formed in approximately 2/3 and formed in the third region M3 is substantially 0.5 times the maximum distance of the stopper 50 in the height direction. Even when the stopper 50 is formed in a size different from that of the present embodiment, the maximum distance of the stopper 50 in the height direction is substantially ½ of the maximum distance of the first region M1 in the height direction. As described above, the average height of the strip-shaped stopper 50 formed in the third region M3 is substantially less than 0.7 times, preferably less than 0.6 times the maximum distance of the stopper 50 in the height direction. It is good to have. That the stopper 50 is “substantially” formed in the height direction means that the stopper 50 is formed as long as the stopper 50 performs the intended function, such as prevention of rewinding of the wrap film 91f and improvement of cutability. This means that the parts that are not present are allowed to exist intermittently.

  Furthermore, in the present embodiment, a gap 51g where the stopper 50 is not formed is formed in a portion of the stopper 50 formed in an arc shape. A plurality of vertically long gaps 51g extending in the height direction (direction in which the wrap film 91f is pulled out) are formed at intervals in the axial direction D. In the present embodiment, the gap 51g is formed so as not to divide the stopper 50 formed along the front plate edge 19 and to leave a band of the stopper 50 of about 3 mm on the front plate edge 19 side. . In the present embodiment, the stopper 50 is also formed on the surface of the front plate 12 outside the left flap 12fA. In the present embodiment, the stopper 50 formed in the main region M between the central region C and the left side plate 15A has an area in the first region M1 that is more than twice the area in the third region M3. It is larger than the area in the second region M2. In other words, the stopper 50 is formed large near the central region C and small near the left side plate 15A.

  With reference to FIG. 3, the summary of the shape of the stopper 50 formed on the left flap 12fA described so far is shown. FIG. 3 is a partial front view around the left flap 12fA of the present embodiment. The stopper 50 is formed of an arc-shaped portion 50a on the central region C side and a strip-shaped portion 50b on the left side plate 15A side. The entire stopper 50 is continuously formed with an interval 50H of about 2 mm between the front plate edge 19 and the front plate edge 19. An interval 50G between the tip of the arc-shaped portion 50a having the maximum height and the cutting line 12cA is formed to be about 4 mm. A gap width 51W, which is the width of the gap 51g formed in the arcuate portion 50a, is about 3 mm common to each gap 51g. The comb width 50W, which is the width of the arc-shaped portion 50a of the portion formed in a comb shape by forming a plurality of gaps 51g, is also about 3 mm. The base height 50aE, which is the height of the base extending in the axial direction D that connects the comb-shaped portions on the front plate edge 19 side, is uniformly formed at about 3 mm. The belt end height 50bE, which is the height of the end of the belt-like portion 50b on the left side plate 15A side, is about 3 mm, and the center height 50bC, which is the height of the belt-like portion 50b at the boundary with the arcuate portion 50a, is about 5 mm. The side of the belt-like portion 50b on the cut line 12cA side is formed in a straight line. Accordingly, the height of the belt-like portion 50b is formed so as to gradually increase from the belt edge to the center of the belt. For this reason, the height of the strip-shaped stopper 50 formed in the third region M3 described above refers to the average height.

  2 and 1 again, the description of the flap 12f will be continued. The right flap 12fB is formed symmetrically with the left flap 12fA about the virtual straight line 12v. The points 12cBN and 12cBS of the right flap 12fB correspond to the points 12cAN and 12cAS of the left flap 12fA, respectively. Also on the right flap 12fB, the stopper 50 is formed in line symmetry with the stopper 50 formed on the left flap 12fA with the virtual straight line 12v as an axis. The stopper 50 is also formed in the central region C along the front plate edge 19 at the same height as the base height 50aE.

  With continued reference to FIGS. 1 and 2, the operation of the wrapped carton 100 will be described. The operation of the wrap carton 1 will be described as a part of the operation of the wrapping carton 100. In the unopened wrapped carton 100, a cut piece (not shown) is connected to the tip of the lid piece 22 via a perforation (not shown) on the tip side 22t. The plate 12 is bonded at a plurality of points. When the wrap film 91f is used for the first time, the cut piece (not shown) is cut off at the perforation (not shown) while being peeled off from the front plate 12, and separated from the lid piece 22. By opening the wrap carton 1 in this way, the lid 20 can be rotated around the rear plate edge 18 with respect to the main body 10.

  The unwrapped carton 100 with a wrap has a wrap roll 91 r in the main body 10. The wrap roll 91r has a drawer seal (not shown) attached to the tip of the wrap film 91f, and the tip of the wrap film 91f is peeled from the wrap roll 91r by pulling out the drawer seal (not shown). The wrap film 91f can be pulled out easily. When the wrap film 91f is used, the wrap film 91f is pulled out from the wrap roll 91r by a necessary length and cut by the cutting blade 23. At this time, the lid portion 20 is closed with the wrap film 91f pulled out by a necessary length, the wrap film 91f is sandwiched between the front plate 12 and the lid cover piece 22, the centroid of the lid cover piece 22 is pressed with the thumb, and the cutting blade When the wrapping carton 100 is twisted around the axis 91a so that the center of the wrap film 91f is drawn into the drawn wrap film 91f, it is easy to cut even when the wrap film 91f is attached to the tableware to be wrapped.

  When the wrap film 91f is pulled out and cut, normally, the center portion in the width direction at the tip of the wrap film 91f is picked and pulled out, and the lid portion 20 is closed and cut without changing. While the wrap film 91f is being cut along the cutting blade 23 from the center portion in the width direction of the wrap film 91f toward the both ends, the wrap film 91f near the center portion in the width direction immediately after being cut is the wrap film 91f. Since there is no tension between the finger gripping the tip, the force drawn toward the end that has not yet been cut acts. For this reason, if it is insufficient to sandwich the wrap film 91f between the front plate 12 and the lid cover piece 22, the wrap film 91f immediately after being cut approaches the end portion, and wrinkles are generated. There is a risk that it cannot be cut. According to the wrap carton 1 according to the present embodiment, since the area of the stopper 50 formed in the first region M1 of the main region M near the center in the width direction of the wrap film 91f is relatively large, The wrap film 91f near the center in the width direction can be suppressed so as not to skid. Further, since the flap 12f is formed in the main region M, the force that the flap 12f pushes the wrap film 91f toward the lid piece 22 acts as an auxiliary, and the wrap film 91f immediately after cutting is prevented from slipping. Will contribute. In the central region C, when the lid cover piece 22 is pushed toward the front plate 12 with the lid portion 20 closed, the lid cover piece 22 and the front plate 12 come into contact with each other. It can be suppressed so as not to skid. These actions are particularly advantageous for a relatively long lap carton of 250 mm or more, such as the wrap carton 1 of the present embodiment in which the length in the axial direction D is 310 mm.

  Since the wrap film 91f sandwiched between the flap 12f and the lid cover piece 22 after being cut is attached to the stopper 50, the wrap film 91f is prevented from being rewound onto the wrap roll 91r. Further, when the wrap film 91f is used next time, when the lid portion 20 is opened, the flap 12f floats outside the main body portion 10, so that the wrap film 91f attached to the stopper 50 formed on the flap 12f The tip also floats from the front plate 12 outside the flap 12f and is easy to pick. In particular, since the flap 12f is not formed in the central region C of the wrap carton 1, since a gap is formed between the central region C and the wrap film 91f, the wrap film can be easily put by inserting a finger into the gap. 91f can be picked. The center area C is between the left flap 12fA and the right flap 12fB, and corresponds to the central portion in the width direction of the wrap film 91f.

  Here, referring to FIG. 4 together with FIG. 1 and FIG. 2, the operation of pulling out the wrap film 91f adhering to the stopper 50 will be described. In pulling out the wrap film 91f picked between the left flap 12fA and the right flap 12fB, first, the wrap film 91f is turned away from the front plate 12 and peeled off from the stopper 50. At this time, the wrap film 91f attached to the stopper 50 along the front plate edge 19 in substantially the entire axial direction D has a portion of the wrap film 91f that has been picked and the wrap attached to the stopper 50. The tension T acts on an imaginary line connecting an arbitrary part of the film 91f. The tension T can be decomposed into a component Tp in the drawing direction P and a component Td in the axial direction D. In the wrap film 91f attached to the stopper 50, the pulling direction component Tp is larger and the axial direction component Td is smaller as the tension T is closer to the center in the width direction, and the pulling direction component Tp is smaller as the tension T is closer to the end. The axial component Td is small and large. For example, the tension T (E) acting on the end portion in the width direction of the wrap film 91f has a greater axial component Td than the tension T (F) acting on the center portion. Since the axial direction component Td generates a shearing force on the wrap film 91f, if the axial direction component Td becomes too large, the wrap film 91f may be broken. According to the wrap carton 1 according to the present embodiment, since the area of the stopper 50 formed in the third region M3 at the end in the width direction of the wrap film 91f is relatively small, the axial direction component Td at the end is An increase in size can be suppressed, and damage to the wrap film 91f can be suppressed.

  As described above, according to the wrap carton 1 according to the present embodiment, the stopper 50 has a ratio of the area formed in the first region M1 to the area formed in the third region M3 is 2 or more. In addition, the area formed in the second region M2 is smaller than the area formed in the first region M1. Thus, since the area where the stopper 50 is formed is large in the first region M1 close to the central region C and small in the third region M3 close to the end portion, the wrap film 91f is directed from the central portion in the width direction to both end portions. When cutting, the wrap film 91f immediately after cutting can be appropriately suppressed so as not to slip, and when the wrap film 91f is pulled out, an increase in shear force can be suppressed to prevent damage to the wrap film 91f. it can.

In the stopper 50 of the wrap carton 1 described above, the gap 51g formed in the arc-shaped portion 50a is filled with a band-shaped base portion extending in the axial direction D on the front plate end side 19 side. It may be configured as follows.
FIGS. 5A and 5B are partial front views showing the left flap 12fA of the wrap carton 1A according to the variation. FIG. 5A is a view showing the stopper 50A, and FIG. The wrap carton 1A according to the variation is different from the stopper 50 (see FIGS. 2 and 3) of the wrap carton 1 in that the stopper 50A is as follows.

  First, the stopper 50A formed on the left flap 12fA will be described. In the arc-shaped portion 50d (corresponding to the arc-shaped portion 50a (see FIG. 3) in the wrap carton 1), the gap 51g penetrates to the front plate edge 19 side. doing. In other words, a plurality of gaps 51g formed in the arcuate portion 50d extending in the height direction are formed at intervals in the axial direction D over the entire height direction. The configuration of the arc-shaped portion 50d other than the above is the same as that of the arc-shaped portion 50a (see FIG. 3) in the wrap carton 1. The configuration of the belt-like portion 50b is the same as that of the wrap carton 1 (see FIGS. 1 to 3). Next, the stopper 50A formed on the surface of the front plate 12 between the left flap 12fA and the left side plate 15A will be described. Compared with the stopper 50 (see FIG. 2) formed on the wrap carton 1, The distance in the vertical direction is the same, but the distance in the axial direction D is long and extends to the cutting line 12cA.

  The size of the stopper 50A formed in the main area M between the central area C and the left side plate 15A in the first area M1, the second area M2, and the third area M3 is the locking area Q (FIG. 5 ( When viewed in terms of the area of B), the relationship is as follows. The “locking region Q” is a portion surrounded by the outer edge of the stopper 50A (locking means), and the “outer edge of the stopper 50A” is a gap 51g where the stopper 50A is not partially formed. Even if it is, it is a boundary which can be seen as the outline of the stopper 50A as a whole by filling the gap 51g (filling with the stopper 50A). In other words, the locking region is a region of the stopper 50A including a portion where the stopper 50A does not exist even if there is a portion where the stopper 50A does not exist (gap 51g). Hereinafter, the locking region Q in the first region M1 is referred to as a first locking region Q1, the locking region Q in the second region M2 is referred to as a second locking region Q2, and the locking region Q in the third region M3 is referred to as a locking region Q. The third locking region Q3. In the wrap carton 1A according to the variation, the area of the first locking region Q1 is larger than the area of the second locking region Q2 and larger than the area of the third locking region Q3. In particular, in the example shown in FIG. 5, the area of the first locking region Q1 is twice or more than the area of the third locking region Q3.

  The height of the stopper 50A in the first region M1, the second region M2, and the third region M3 is the same as that of the stopper 50 (see FIG. 2) in the lap carton 1. Further, the stopper 50A is formed symmetrically about the virtual straight line 12v (see FIG. 2) as an axis, like the wrap carton 1 (see FIG. 2). The stopper 50A configured as described above is easier to pull out the wrap film 91f while keeping the slippage (easy to cut) when cutting the wrap film 91f as compared with the stopper 50 (see FIG. 3). Can be improved. In consideration of the balance between ease of cutting and pulling out of the wrap film 91f, the area of the second locking region Q2 is 70% or less, preferably 1/2 or less, of the area of the first locking region Q1. The maximum height HQ2 of the second locking region Q2 is lower than the maximum height HQ1 of the first locking region Q1, and the area of the third locking region Q3 is 70% of the area of the first locking region Q1. Hereinafter, it is preferable to set it to 1/2 or less, and the maximum height HQ3 of the third locking region Q3 may be lower than the maximum height HQ1 of the first locking region Q1.

  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. Even in this case, the area where the stopper 50 is formed is smaller in the third region M3 closer to the end than the first region M1 close to the central region C, so that the shear when pulling out the wrap film 91f is reduced. The increase in force can be suppressed and damage to the wrap film 91f can be suppressed.

  In the above description, the left flap 12fA and the right flap 12fB are formed on the front plate 12. However, the flap 12f is not formed at all, or one flap 12f may not be formed. Even if the flap 12f is not formed, the side slip at the time of cutting can be suppressed while the damage at the time of pulling out the wrap film 91f is suppressed by the stopper 50 being formed at a predetermined position. However, when the flap 12f is formed, the distance between the front plate 12 and the lid lid piece 22 when the lid portion 20 is closed becomes small and the wrap film 91f is likely to adhere to the stopper 50. The effect of preventing rewinding can be improved.

In the above description, the gap 51g is formed in the arc-shaped portion 50a of the stopper 50. However, the gap 51g may not be formed, and the stopper 50 may be formed in a different manner from the above. Good.
6 (A) and 6 (B) are diagrams showing a modification of the stopper formed in the lap carton according to the embodiment of the present invention, and FIG. 6 (C) shows a pattern according to the first comparative example. FIG. 6 (D) is a view showing a stopper according to the second comparative example. The stopper 55 according to the first modification shown in FIG. 6A has substantially the same contour as the stopper 50 (see FIG. 3) (therefore, the first region M1, the second region M2, and the third region M3). The area ratio in FIG. 3 is also substantially the same), except that a gap that divides in the axial direction D is formed in a portion corresponding to the band-like portion 50b of the stopper 50 shown in FIG. 3, and the stopper 55 is formed in an island shape. ing. The stopper 56 according to the second modification shown in FIG. 6B has a contour and an area ratio in the first to third regions M1, M2, and M3 that are substantially the same as the stopper 50 (see FIG. 3). The difference is that 57 g is formed to extend in the axial direction D.

  In the first comparative example shown in FIG. 6C, no stopper is formed. For convenience of comparison, this aspect is denoted by reference numeral 58 and referred to as a pattern 58. That is, the pattern 58 is a mode in which no stopper is formed on any of the flaps 12f. In the pattern 58 according to the first comparative example, when the wrap film 91f is cut at both ends, it is difficult to suppress the side slip of the wrap film 91f immediately after cutting. The stopper 59 according to the second comparative example shown in FIG. 6D is formed over substantially the entire surface of the flap 12f, and the area of the first region M1 is predetermined with respect to the areas of the other regions M2 and M3. It is not sized. In the stopper 59 according to the second comparative example, when the width center of the tip of the wrap film 91f is picked and pulled out, a large shearing force is generated at the end of the wrap film 91f attached to the stopper 59, and the wrap film 91f is damaged. There is a fear.

  The stopper 50 according to the embodiment shown in FIG. 3, the stoppers 55 and 56 according to the first and second modifications shown in FIGS. 6A and 6B, and the first shown in FIG. 6C. A wrapped carton in which the pattern 58 according to the comparative example and the stopper 59 according to the second comparative example shown in FIG. 6D are formed (same as the wrapped carton 100 shown in FIG. 1 except for the form of each stopper). , Have 30 people use the monitor and evaluate the ease of cutting the wrap film 91f from the center of the width to both ends and the ease of pulling out the wrap film 91f attached to the stopper. received.

  FIG. 7 shows a graph of the evaluation results. The evaluation is selected from five levels: 1: bad, 2: somewhat bad, 3: normal, 4: slightly good, 5: good, and the vertical axis of the graph of FIG. The horizontal axis indicates the type of stopper (pattern). In the graph of FIG. 7, the shaded bar graph indicates the ease of cutting, and the unmarked bar graph indicates the ease of withdrawal. The stopper 50 according to the embodiment and the stoppers 55 and 56 according to the first and second modified examples both exceed 3.0 in terms of ease of cutting and ease of pulling out. The pattern 58 according to the first comparative example is very easy to pull out, but is very easy to cut. The stopper 59 according to the second comparative example is extremely easy to cut, but is extremely low in pulling out. For this reason, it is difficult to employ the pattern 58 according to the first comparative example and the stopper 59 according to the second comparative example.
