JP5963521B2 - A container for storing a wound body wound with a long object and a container containing the wound body - Google Patents

Description

  The present invention relates to a container that can accommodate a wound body on which a thin film-like long object is wound, and a container containing a wound body, and in particular, a container and a winding that can appropriately cut a long object. It relates to a container with a body.

  A thin film-like object, such as a food wrap film, that can wrap foods, dishes or dishes such as dishes together with dishes is widely used. A food wrap film (hereinafter also simply referred to as a film) is typically housed in a rectangular parallelepiped container in a wound state wound in a roll shape. The container generally includes a bottom plate, a front plate, a rear plate, and a pair of side plates, and is a main body portion having an open top surface that can accommodate a wound body, and a rear body portion. A lid that is pivotally connected to the upper edge of the face plate and can close the opening of the main body. The lid is attached with a cutting blade capable of cutting the film after it is pulled out from the wound body by a necessary amount.

  Generally, the container is provided with a mechanism for preventing the wound body from jumping out of the container when the film is pulled out of the container. For example, in the container described in Patent Document 1, a plate-shaped fixed piece, and the width direction of the fixed piece configured to be directed in the vertical direction, that is, the direction in which the wound body tends to jump out, In the vicinity of the side plate of the main body, it is provided above the accommodated wound body. This fixing piece is connected via a crease line to a reinforcing plate attached to the inner surface of the front plate in order to reinforce the front plate of the main body. Further, the fixed piece is bent inward of the container along the fold line so that the fixed piece reaches above the wound body.

  In addition, when the width direction of a fixed piece faces an up-down direction as mentioned above, a lower edge will contact a winding body among the upper edge and the lower edge which are the edges of the width direction of a fixed piece. In this case, preferably, the lower edge of the fixed piece has a shape suitable for the outer peripheral surface of the wound body, for example, an arc shape so that the lower edge of the fixed piece can effectively contact the wound body. ing.

Japanese Patent No. 4244165

  By the way, when the lower edge of the fixed piece has a shape adapted to the outer peripheral surface of the wound body as described above, the shapes of the upper edge and the lower edge of the fixed piece become asymmetric. For this reason, when the fixing piece is bent inside the container along the crease line, the force and torque (hereinafter also simply referred to as force) acting on the crease line become non-uniform. For example, when a predetermined force is applied to the tip of the fixed piece to bend the fixed piece, the force transmitted to the crease line through the fixed piece may be different between the upper edge side and the lower edge side of the fixed piece. In this case, on either the upper edge side or the lower edge side of the fixed piece, the fixed piece is bent along the portion other than the crease line with respect to the reinforcing plate, and as a result, the arrangement and orientation of the fixed piece are not intended. May end up.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1A to 8. First, the entire container 1 in the present embodiment will be described with reference to FIG. 1A. In addition, in each figure, the same or similar code | symbol is attached | subjected to the mutually same or similar member, and the overlapping description is abbreviate | omitted.

Container FIG. 1A is a perspective view showing a container 100 containing a wrap roll (rolled body). The wrap roll 91r is in the form of a roll obtained by winding a long thin film, for example, a wrap film 91f, around its axis 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”. The wrap film 91f is, for example, a film having a thickness of 5 to 20 μm formed using polyvinylidene chloride as a raw material. The container 1 includes a main body 10 that can accommodate the wrap roll 91r, and a lid 20 that is rotatably connected to the main body 10.

(Main body)
The main body 10 is a rectangular parallelepiped box having a size that can accommodate an unused wrap roll 91r, and one of its elongated surfaces is opened to form an opening surface 10h. The size of the main body 10 is as small as possible while forming a gap that does not prevent the accommodated unused lap roll 91r from rotating around the axis 91a. For example, the main body 10 is formed with a size of 44 mm in width, 44 mm in height, and 310 mm in length. The main body 10 includes a front plate 12, a bottom plate 13, a rear plate 14 that form side surfaces extending in the longitudinal direction of the rectangular parallelepiped together with the opening surface 10h, and a pair of 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 plate 15 is typically formed in a square shape, but may have a rectangular shape with 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, based on the state where the bottom plate 13 is placed on a horizontal surface.

  At the central portion of the upper edge of the side plate 15, there is provided a protrusion 15p formed by folding back a small piece extending upward by about 3 mm. Further, the upper edge 19 of the front plate 12 is connected to a reinforcing plate 31 that is folded along the inner surface of the front plate 12 with the upper edge 19 as a ruled line (fold line) 31r (FIGS. 4 and 8). reference). The reinforcing plate 31 is substantially the same size as the front plate 12 but is not in contact with the bottom plate 13. The lower edge of the reinforcing plate 31 is bonded to the inner surface of the front plate 12 along the longitudinal direction of the reinforcing plate 31.

  The fixing piece 17 is connected to the reinforcing plate 31 through a crease line 17r formed in the reinforcing plate 31 in the vicinity of the side edge 31b of the reinforcing plate 31. The fixed piece 17 is a member for preventing the lap roll 91r from jumping out by contacting the lap roll 91r from above. Here, “the vicinity of the side edge 31 b of the reinforcing plate 31” means the position of the crease line 17 r so that the path of the wrap film 91 f pulled out from the wrap roll 91 r is not significantly hindered by the fixing piece 17. It means that. The detailed configuration of the fixed piece 17 will be described later.

(Cover)
The lid 20 is a member that is connected to the upper edge 18 of the rear plate 14 of the main body 10 and can close the opening surface 10 h of the main body 10. The lid 20 includes a lid top plate 21, a lid front plate 22, a cutting blade 23, and a lid side plate 25. The lid portion 20 is configured to be rotatable with respect to the main body portion 10 with the upper edge 18 of the rear plate 14 of the main body portion 10 as a rotation axis.

  The lid front plate 22 is provided so as to be orthogonal to the lid top plate 21 via the crease line 22r and extend toward the bottom plate 13 when the lid 20 is closed. For this reason, the lid front plate 22 can at least partially overlap the front plate 12 of the main body 10 when the lid 20 closes the opening surface 10 h of the main body 10. The lid front plate 22 has a height (the length of the lid front plate 22 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 “axial direction D”). The height of the front plate 12 in the short side direction is about ½, and the height at the center in the axial direction D is about 3/4 of the length of the front plate 12 in the short side direction. Yes. The tip 22t facing the crease line 22r is configured such that the distance between the crease line 22r and the tip 22t decreases in the axial direction D from the center to the end. For this reason, the front-end | tip part 22t facing the crease line 22r has a V-shape. The lid front plate 22 overlaps the outer surface of the front plate 12 along the front plate 12 when the lid 20 is closed, and covers the upper portion of the front plate 12 in a pentagonal shape. The lid front plate 22 is configured so that the wrap film 91f drawn from the wrap roll 91r accommodated in the main body 10 can be sandwiched between the front plate 12 over the entire width. A cutting blade 23 for cutting the wrap film 91f is attached to the tip 22t of the lid front plate 22. The cutting blade 23 is provided in a V shape along the tip 22t so that the cutting edge protrudes from the tip 22t.

  The lid side plate 25 is provided so as to be orthogonal to both the lid top plate 21 and the lid front plate 22. The lid side plate 25 is connected to both ends of the lid upper plate 21. Further, joining pieces 22j are connected to both ends of the lid front plate 22, and the joining pieces 22j are fixed to the inner surface of the lid side plate 25 with an adhesive or the like. The joining piece 22j is configured to have an area smaller than that of the lid side plate 25, and therefore, a step portion 25d resulting from the thickness of the joining piece 22j is formed inside the lid side plate 25. The step portion 25d is configured such that a projection 15p provided on the upper edge of the side plate 15 is fitted when the lid portion 20 is closed.

  The main body 10 and the lid 20 are formed by processing coated cardboard having a thickness of about 0.45 mm to 0.7 mm, for example. For this reason, the container 1 has predetermined 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 generally manufactured by first cutting out one base paper to form a paperboard and then forming the paperboard 50 by bending or the like. That is, the main body 10 and the lid 20 are integrally formed.

(flap)
As shown in FIG. 1A, the front plate 12 of the main body 10 can protrude forward from the front plate 12, and the lap drawn from the wrap roll 91r when the opening surface 10h is closed. A flap 12f configured to sandwich the film 91f with the lid front plate 22 of the lid portion 20 is provided. Hereinafter, the flap 12f will be described in detail with reference to FIGS. 1B to 3.

  1B and 1C are a cross-sectional view and a perspective view showing the vicinity of the flap 12f of the container 1 in an enlarged manner. FIG. 2 is a front view showing the container 1 with the lid 20 open. In the present embodiment, the flaps 12f are provided on both sides of the central region 12t along the upper edge 19 of the front plate 12 so as to sandwich the central region 12t located at the upper center of the front plate 12. Here, the “central region 12t” means that the centroid of the lid front plate 22 (a part of the lid front plate 22 near the top of the V-shape of the tip 22t) faces the front plate 12 with the lid 20 closed. It is a part of the front plate 12 that the lid front plate 22 contacts when pushed. In addition, since the container 1 has elasticity, the range in which the lid front plate 22 and the front plate 12 are in contact with each other can be changed according to the magnitude of the force pushing the lid front plate 22 toward the front plate 12. Therefore, when the central region 12t is defined, when the centroid of the lid front plate 22 is pushed toward the front plate 12 with the unused lap roll 91r accommodated in the main body 10, the front plate 12 A portion of the front plate 12 that comes into contact with the lid front plate 22 when stopped by the lap roll 91r in the main body 10 and stops moving to the rear plate 14 side is defined as a central region 12t.

  Regarding the two flaps 12f provided with the central region 12t in between, for convenience of explanation, in front view (see FIG. 2), the flap 12f on the left side of the central region 12t is referred to as a left flap 12fA (first flap). The right flap 12f of 12t is referred to as a right flap 12fB (second flap). Hereinafter, when a configuration common to the left flap 12fA and the right flap 12fB is described, it may be simply referred to as a “flap 12f”. Further, the side plate 15 close to the left flap 12fA may be referred to as a left side plate 15A (first side plate), and the side plate 15 close to the right flap 12fB may be referred to as a right side plate 15B (second side plate). The side plate 15 is a general term for the left side plate 15A and the right side plate 15B.

  The outline of the left flap 12fA is constituted by a cut line 12cA formed in the surface of the front plate 12 and an upper edge 19 of the front plate 12. The cut line 12cA is a line that cuts a part of the front plate 12. The cut line 12cA passes from the point 12cAN on the upper edge 19 close to the central region 12t closer to the left side plate 15A than the central region 12t to the point on the upper edge 19 that passes through the surface of the front plate 12 and is close to the left side plate 15A. It is formed by cutting the surface of the front plate 12 so as to reach 12cAS. The point 12cAN is positioned in the vicinity of the central region 12t to such an extent that the wrap film 91f does not slip so that the cut edge of the wrap film 91f is unacceptable when the drawn wrap film 91f is cut. In the example shown in FIG. 2, the point 12cAS is located slightly closer to the center region 12t than the left end of the drawn wrap film 91f. However, the present invention is not limited to this, and the point 12cAS may be located between the left end of the wrap film 91f and the left side plate 15A. “Slightly closer to the center region 12t than the left end of the wrap film 91f” means that the wrap film 91f is sandwiched between the left flap 12fA and the lid front plate 22 so that the wrap film 91f can be cut without sagging when the wrap film 91f is cut. This means that the position of the point 12cAS is determined.

  When the left end of the left flap 12fA is formed closer to the central region 12t than the left end of the wrap film 91f, a decrease in strength of the main body 10 around the side edge of the front plate 12 in the axial direction D can be suppressed. . In the present embodiment, in the axial direction D, the left end of the left flap 12fA is formed closer to the central region 12t by 15 mm than the left side edge of the front plate 12, but the present invention is not limited to this. It may be formed closer to the central region 12t by 5 mm. The maximum protrusion length of the left flap 12fA is set to about ½ of the length of the front plate 12 in the vertical direction. In the present embodiment, the lower side (front end side) of the left flap 12fA once again approaches the upper edge 19 side once again when moving from the central region 12t side in the axial direction D toward the left side plate 15A side. It is formed in a smooth curve away from the edge 19. In other words, the center portion of the left flap 12fA is recessed closer to the upper edge 19 than both end portions. The left flap 12fA is formed in a size that is covered with the cover front plate 22 and does not appear on the outer surface when the cover 20 is closed.

  In general, the shorter the distance between both ends 12cAN, 12cAS of the cut line 12cA constituting the outline of the left flap 12fA and the upper edge 19 of the front plate 12, the more apart the left flap 12fA is from the reinforcing plate 31, that is, the degree to which it floats. Becomes larger. Further, when both ends 12cAN and 12cAS reach the upper edge 19, the degree to which the left flap 12fA floats is further increased. In the present embodiment, both ends 12cAN and 12cAS of the cut line 12cA constituting the outline of the left flap 12fA may reach the upper edge 19 of the front plate 12.

  A stopper 12s for locking the wrap film 91f may be formed on the surface of the left flap 12fA. The stopper 12s is formed by, for example, UV varnish applied on the left flap 12fA. As shown in FIG. 1C, similar stoppers 12s and 19s may be formed on the front plate 12 or the upper edge 19 of the front plate 12 between the left flap 12fA and the left side plate 15A.

  The right flap 12fB is formed symmetrically with the left flap 12fA about a virtual straight line 12v that bisects the front plate 12 to the left and right. The points 12cBN and 12cBS of the right flap 12fB correspond to the points 12cAN and 12cAS of the left flap 12fA, respectively.

  As described above, the flap 12f is formed by raising a part of the front plate 12 along a score line formed in the plane of the front plate 12. In this case, when the opening surface 10h of the main body portion 10 is closed by the lid portion 20, a phenomenon that the flap 12f is fitted into the front plate 12 may occur. In order to prevent such a phenomenon from occurring, as shown in FIG. 1B, the outer surface of the reinforcing plate 31 is provided with a convex portion 32 that can contact the inner surface of the flap 12f when the lid portion 20 is closed. It may be done. As a result, the flap 12f can be prevented from fitting into the front plate 12, and the flap 12f can thereby function stably.

  The method for forming the convex portion 32 is not particularly limited, and various methods can be adopted. For example, the convex portion 32 can be formed on the outer surface of the reinforcing plate 31 by embossing the inner surface of the reinforcing plate 31. In this case, a recess is formed on the inner surface of the reinforcing plate 31 as shown in FIG. 1B. In the following description and drawings, these convex portions and concave portions may be represented by the same reference numeral 32.

  As long as the flap 12f can be prevented from fitting into the front plate 12, the shape and arrangement of the convex portions 32 are not particularly limited. FIG. 3 is a view showing a state where the flap 12f is removed for convenience from the container 1 shown in FIG. As shown in FIG. 3, a plurality of convex portions 32 may be provided so that the flap 12 f can be intermittently contacted over substantially the entire area of the flap 12 f in the axial direction D.

(Fixed piece)
Next, the fixed piece 17 of the main body 10 will be described in detail. As shown in FIG. 1A, the two fixing pieces 17 are reinforced in the vicinity of the side edge 31b of the reinforcing plate 31 on the left side plate 15A side or the right side plate 15B side so as to be in contact with the left side plate 15A or the right side plate 15B. It is connected to the plate 31. In FIG. 1A, the left fixed piece 17 is referred to as a left fixed piece 17A (first fixed piece), and the right fixed piece 17 is referred to as a right fixed piece 17B (second fixed piece). Hereinafter, when a configuration common to the left fixed piece 17A and the right fixed piece 17B is described, it may be simply referred to as a “fixed piece 17”.

  First, the structure of the fixed piece 17 will be described with reference to FIGS. 4 to 6. 4 is an enlarged perspective view showing the fixing piece 17 of the container 1 when the wrap roll 91r is not accommodated, and FIG. 5 is a perspective view showing a state where the wrap roll 91r is accommodated in the container 1. It is. FIG. 6 is an enlarged plan view showing the fixed piece 17. Note that the structures of the left fixed piece 17A and the right fixed piece 17B are symmetrical with respect to the center of the main body 10 in the longitudinal direction. Therefore, in the following description, various structures of the fixed piece 17 will be described with reference to only one of the left fixed piece 17A and the right fixed piece 17B.

  As shown in FIGS. 4 and 5, the left fixed piece 17 </ b> A is configured to be able to extend to the container 1 with the crease line 17 r of the reinforcing plate 31 as a base. The left fixed piece 17A includes an upper edge 17c extending from the base portion 17f into the container 1, a lower edge 17d extending from the base portion 17f into the container 1 below the upper edge 17c, and the upper edge 17c and the lower edge 17d. And a distal end portion 17e facing the base portion 17f. That is, the outline of the left fixed piece 17A is formed by the upper edge 17c, the lower edge 17d, the tip portion 17e, and the base portion 17f.

  The left fixed piece 17A is configured such that the width direction of the left fixed piece 17A can be directed in the vertical direction when the left fixed piece 17A extends to the container 1. Here, the width direction is a planar direction of the plate-like left fixed piece 17A (a direction orthogonal to the thickness direction of the left fixed piece 17A). Note that “facing in the vertical direction” means that the planar direction of the left fixed piece 17A has at least a component in the vertical direction. For example, when the components in the plane direction of the left fixed piece 17A are classified into the vertical component and the horizontal component, the vertical component and the horizontal component are equivalent. That is, the plane direction of the left fixed piece 17A is about 45 degrees with respect to the horizontal direction.

  In this case, the vertical force generated when the wrap roll 91r is about to jump out of the main body portion 10 acts on the left fixed piece 17A in parallel or substantially parallel to the plane direction of the left fixed piece 17A. In general, a plate-like member such as the left fixed piece 17A has a larger section modulus with respect to a force applied in the plane direction than a force applied in the thickness direction. For this reason, according to the present embodiment, the left fixed piece 17A can stop the lap roll 91r from floating upward. Moreover, since the lower edge 17d of the left fixed piece 17A and the outer peripheral surface of the wrap roll 91r are in line contact with each other instead of being planar, the contact area between the left fixed piece 17A and the wrap roll 91r can be reduced. Accordingly, it is possible to suppress the rotation of the wrap roll 91r when the wrap film 91f is pulled out from being inhibited by the left fixed piece 17A.

  As shown in FIGS. 4 and 5, the lower edge 17d of the left fixed piece 17A has a shape suitable for the outer peripheral surface of the wrap roll 91r, for example, an arc shape. As a result, the lap roll 91r can slide smoothly with respect to the left fixed piece 17A. As a result, it is possible to improve the rotation of the wrap film 91f when the wrap film 91f is pulled out and to prevent the wrap film 91f from moving in the front-rear direction in the main body portion 10.

  On the other hand, as shown in FIGS. 4 and 5, the upper edge 17c of the left fixed piece 17A is configured to extend substantially parallel to the upper edge at substantially the same height as the upper edge of the left side plate 15A. Yes. For this reason, the left fixed piece 17A in the width direction can be ensured as large as possible while preventing the left fixed piece 17A from protruding largely upward from the upper edge of the left side plate 15A. Accordingly, the resistance force exerted on the lap roll 91r by the left fixed piece 17A can be increased as much as possible while suppressing the phenomenon that the closing of the lid portion 20 is inhibited by the left fixed piece 17A. . Note that “extends substantially parallel to the upper edge” means that the maximum distance in the vertical direction between the upper edge of the left side plate 15A and the upper edge 17c of the left fixed piece 17A is 0.2 mm or less. It means that

  By the way, when the upper edge 17c and the lower edge 17d of the left fixed piece 17A are configured as described above, the shapes of the upper edge 17c and the lower edge 17d are asymmetric. For example, when a perpendicular line is drawn from the distal end portion 17e of the left fixed piece 17A to the base portion 17f, the perpendicular line intersects the base portion 17f at the upper edge 17c with respect to the central portion of the base portion 17f. Specifically, as shown in FIG. 6, when a perpendicular line 17en is drawn from the center point 17ec of the tip end part 17e to the base part 17f, an intersection point 17rm of the perpendicular line 17en and the base part 17f is a center point 17fc of the base part 17f. It is located on the upper edge 17c side. In this case, when a predetermined force is applied to the distal end portion 17e of the left fixed piece 17A to bend the left fixed piece 17A along the crease line 17r, the force transmitted to the crease line 17r via the left fixed piece 17A is It is considered that the upper edge 17c side and the lower edge 17d side of the fixing piece 17A are different. For example, the force transmitted to the fold line 17r on the lower edge 17d side of the left fixed piece 17A (hereinafter also referred to as the lower fold line 17rb) is a fold line 17r on the upper edge 17c side (hereinafter referred to as the upper edge side fold). It may be less than the force transmitted to the line of sight 17ra). Further, as shown in FIG. 6, the lower edge 17d has a shape that is recessed toward the inside of the left fixed piece 17A. Therefore, the force applied to the distal end portion 17e is applied to the lower edge side fold line 17rb. Is thought to be difficult to communicate properly. In such a case, on the lower edge 17d side, there is a possibility that the left fixed piece 17A is bent at a place other than the crease line 17r with respect to the reinforcing plate 31.

  In order to prevent such unintended folding from occurring, in the present embodiment, the crease line 17r is configured to have higher foldability at the lower edge side crease line 17rb than at the upper edge side crease line 17ra. That is, the lower edge side crease line 17rb is easier to bend than the upper edge side crease line 17ra. For this reason, even if it is a case where force is not easily transmitted from the front-end | tip part 17e to the lower edge side crease line 17rb, the left fixed piece 17A can be appropriately bent along the lower edge side crease line 17rb with respect to the reinforcing plate 31. . Thereby, the left fixed piece 17A provided in a desired arrangement and orientation can be obtained more reliably. For example, the upper edge 17c of the left fixed piece 17A can be more reliably extended substantially parallel to the upper edge at substantially the same height as the upper edge of the left side plate 15A.

  The method for evaluating the bendability of the upper edge side crease line 17ra and the lower edge side crease line 17rb is not particularly limited, and various methods can be used. For example, first, a first sample having a crease line having a structure equivalent to the upper edge side crease line 17ra and a second sample having a crease line having a structure equivalent to the lower edge side crease line 17rb are prepared. Next, the first sample and the second sample are bent, and the force required at that time is measured. Based on this measurement value, the bendability of the upper edge side crease line 17ra and the lower edge side crease line 17rb can be evaluated.

  The specific structure of the crease line 17r including the upper edge crease line 17ra and the lower edge crease line 17rb as described above is not particularly limited. For example, the crease line 17r may be configured as a perforation including a plurality of joints and breaks arranged in order. In the example shown in FIG. 6, the crease line 17r includes the first joint CPa, the first fractured part BPa, the second joint CPb, the second fractured part BPb, the third joint CPc, and the first 3 rupture portion BPc is included. Among these, the upper edge side crease line 17ra is configured by the first joint CPa, the first fracture BPA, and the second joint CPb, and the second fracture BPb, the third junction CPc, and the third fracture BPc An edge side crease line 17rb is formed.

  In the example shown in FIG. 6, the crease line 17r is a ratio of the total length of the rupture part to the total length of the joint part in the lower edge crease line 17rb (hereinafter also referred to as a rupture part ratio of the lower edge crease line 17rb). ) In the upper edge side crease line 17ra is configured to be larger than the ratio of the total length of the rupture portion to the total length of the joint portion (hereinafter also referred to as the rupture portion ratio of the upper edge side crease line 17ra). ing. For example, the lengths of the first joint portion CPa, the first fracture portion BPa, the second joint portion CPb, the second fracture portion BPb, the third joint portion CPc, and the third fracture portion BPc are 2.5 mm and 3.5 mm, respectively. 2.0 mm, 3.5 mm, 1.0 mm and 3.5 mm. In this case, the breaking portion ratio of the upper edge side crease line 17ra is 3.5 mm / (2.5 mm + 2.0 mm) = 0.78, while the breaking portion ratio of the lower edge side crease line 17rb is (3. 5 mm + 3.5 mm) /1.0 mm = 7.0. By thus configuring the upper edge side fold line 17ra and the lower edge side fold line 17rb, the lower edge side fold line 17rb can be more easily bent than the upper edge side fold line 17ra.

  The absolute values of the lengths of the respective joint portions and the respective fracture portions are not particularly limited. Preferably, the length of the joint portion at the lower edge side fold line 17rb is 1.6 mm or less, and the upper edge side folding is performed. The length of the joint at the line of sight 17ra is greater than 1.6 mm. “1.6 mm or less” is a concept including the case where the joint portion is 0.0 mm. Here, “the joint portion is 0.0 mm” means that the lower edge side crease line 17rb is constituted only by the fracture portion. As supported in the embodiments described later, by setting the length of the joint portion in this way, the left fixed piece 17A can be more reliably bent along the lower edge side crease line 17rb. In order to reduce the risk of the left fixed piece 17A being damaged, the length of the joint portion on the lower edge side crease line 17rb is set to a predetermined value larger than 0.0 mm, for example, 0.5 mm or more. Also good.

  More preferably, the length of the joint portion at the lower edge side crease line 17rb is 1.3 mm or less. As is supported in the embodiments described later, by setting the length of each joint portion in this way, the left fixed piece 17A can be more reliably bent along the lower edge side fold line 17rb.

  The effect obtained by configuring the crease line 17r as described above will be further described with reference to FIG. In FIG. 7, the shift in the vertical direction between the upper edge of the right side plate 15B of the main body 10 and the upper edge 17c of the lower edge side crease line 17rb is represented by an arrow with a symbol Δh. According to the present embodiment, by configuring the crease line 17r as described above, the right fixed piece 17B can be appropriately bent along the crease line 17r, and as a result, the deviation Δh can be reduced from −0.2 mm to −0.2 mm. It can be in the range of +0.2 mm. Here, Δh is a plus sign, meaning that the upper edge 17c of the right fixed piece 17B is located above the upper edge of the right side plate 15B. On the other hand, the fact that Δh is a minus sign means that the upper edge 17c of the right fixed piece 17B is positioned below the upper edge of the right side plate 15B. According to the present embodiment, by setting the shift Δh within the range of −0.2 mm to +0.2 mm, the right fixing piece 17B is prevented from protruding greatly upward from the upper edge of the right side plate 15B. The dimension of the right fixed piece 17B in the width direction can be as large as possible. Naturally, the same effect as that of the right fixed piece 17B can be obtained with respect to the left fixed piece 17A.

(Presser plate)
In addition to the fixed piece 17, a member for preventing the wrap roll 91 r from jumping out may be provided in the container 1. For example, as shown in FIG. 1B and FIGS. 3 to 5, a holding plate 33 that extends along the axial direction D and protrudes toward the wrap roll 91 r may be provided in the container 1. For example, as shown in FIGS. 1B and 3, the pressing plate 33 is formed by raising a part of the reinforcing plate 31 along a cut line 33 c formed in the surface of the reinforcing plate 31.

  The pressing plate 33 may be provided on both sides of the central region 12t, similarly to the flap 12f. Hereinafter, the pressing plate 33 on the left side of the central region 12t may be referred to as a right pressing plate 33A (first pressing plate), and the pressing plate 33 on the right side of the central region 12t may be referred to as a left pressing plate 33B (second pressing plate). . As shown in FIG. 3, each pressing plate 33A, 33B may be provided so as to overlap each flap 12fA, 12fB when viewed from the horizontal direction.

Method for producing a container Next, a method of manufacturing the container 1. As described above, the container 1 is obtained by first cutting out one base paper to form a paperboard, and then forming the paperboard by bending or the like. FIG. 8 is a plan view showing an example of a paperboard 50 for producing the container 1.

  In the paperboard 50 shown in FIG. 8, the area | region for comprising the various board | plates and pieces of the container 1 is shown with the same code | symbol as the case of FIG. 1A thru | or FIG. Further, in order to bend various plates and pieces, ruled lines and crease lines located between the plates or between the plates and pieces are denoted by reference numerals 12r, 13r, 15r, 15pr, 17r, 21r, 22jr, 25r, 31r, 36r, 37r and the like. Furthermore, cut lines for raising various members are indicated by reference numerals 12cA, 12cB, 33c, 17rc, and the like.

  Also, the front plate 12 has a joining piece 36 (first joining piece 36A and second joining piece) adhered to the side plate 15 (or joining piece 37 described later) in order to fix the angle of the front plate 12 with respect to the bottom plate 13. 36B) are connected via a ruled line 36r. Similarly, a joining piece 37 (first joining piece 37A and second joining piece) bonded to the side face plate 15 (or the joining piece 36 described above) in order to fix the angle of the rear face plate 14 with respect to the bottom face plate 13 is attached to the rear face plate 14. The joining pieces 37B) are connected via ruled lines 37r.

  As shown in FIG. 8, the portion constituting the reinforcing plate 31 of the paperboard 50 extends sideward until the side edge 31 b exceeds the crease line 17 r of the fixed piece 17. By configuring the reinforcing plate 31 in this way, in the container 1 obtained from the paperboard 50, the reinforcing plate 31 can be brought to the vicinity of the side edge of the front plate 12, and thereby the side edge of the front plate 12 The strength of the main body 10 around can be increased. On the other hand, in this case, the portion of the paperboard 50 that constitutes the lower edge 17d of the fixed piece 17 is at least partially adjacent to the portion of the paperboard 50 that constitutes the reinforcing plate 31 via the score line 17rc. .

  The method for producing the paperboard 50 shown in FIG. 8 is not particularly limited, and various methods can be used. For example, first, one base paper is cut out and the outline of the paperboard 50 is adjusted. Next, or simultaneously with the cutting from the base paper, each score line is formed on the paperboard 50. Then, each ruled line, the convex part 32 (or the concave part 32), etc. are formed in the paperboard 50 by embossing etc. with respect to the paperboard 50. FIG.

  The method for producing the container 1 by forming the paperboard 50 is not particularly limited, and various methods can be used. By the way, there is a possibility that the process of bending or cutting a plate or piece interferes with each other. For example, in the present embodiment, the flaps 12f are provided on both sides of the central region 12t. As a result, as shown in FIG. 8, the left flap 12fA extends to the vicinity of the left fixed piece 17A, and the right flap 12fB It extends to the vicinity of the right fixed piece 17B. For this reason, the process of bending the fixing piece 17 may interfere with the process of cutting the flap 12f, or may be hindered by the presence of the cut and raised flap 12f. Since the direction in which the flap 12f is cut and the direction in which the fixing piece 17 is bent are reversed, it is considered that there is a high possibility that such interference and inhibition will occur. Here, according to the present embodiment, as described above, the crease line 17r is configured to have higher bendability at the lower edge side crease line 17rb than the upper edge side crease line 17ra. For this reason, even if the process of bending the fixing piece 17 is a case where interference or inhibition due to the flap 12f is received, the fixing piece 17 can be appropriately bent along the crease line 17r.

  As described above, the portion of the paperboard 50 that forms the lower edge 17d of the fixed piece 17 is at least partially adjacent to the portion of the paperboard 50 that forms the reinforcing plate 31 via the cut line 17rc. . In this case, due to the presence of the reinforcing plate 31, it is difficult to apply a force to the fixed piece 17 in the vicinity of the crease line 17r. Therefore, in the step of bending the fixed piece 17, the fixed piece 17 is bent by applying a force to a portion of the fixed piece 17 away from the crease line 17 r. That is, it is considered difficult to transmit the force uniformly to the crease line 17r. Even if such a restriction occurs, according to the present embodiment, the crease line 17r is configured to have higher bendability at the lower crease line 17rb than the upper crease line 17ra. . For this reason, even if the step of bending the fixing piece 17 is subject to interference or inhibition due to the presence of the reinforcing plate 31, the fixing piece 17 can be appropriately bent along the crease line 17r.

  8 shows an example in which the portion of the paperboard 50 that forms the lower edge 17d of the fixed piece 17 is adjacent to the portion of the paperboard 50 that forms the reinforcing plate 31 via the cut line 17rc. However, the present invention is not limited to this, and as shown in FIG. 9, in the paperboard 50, the portion constituting the fixed piece 17 may extend outward from the portion constituting the side edge 31 b of the reinforcing plate 31. . In view of increasing the strength of the main body 10 around the side edge of the front plate 12, the paperboard 50 shown in FIG. 8 is preferable.

  Next, the operation of the container 1 manufactured as described above will be described.

  When using the wrap film 91f, the wrap film 91f is pulled out from the wrap roll 91r by a necessary length and cut by the cutting blade 23. At this time, the lid 20 is closed with the wrap film 91f pulled out by a required length, the wrap film 91f is sandwiched between the front plate 12 and the lid front plate 22, and the centroid of the lid front plate 22 is pressed with the thumb. When the container 100 with a wound body is twisted around the axis 91a so that the center of the cutting blade 23 is inserted 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. It is.

  When the wrap film 91f is cut, the cutting blade 23 is put in a state in which tension is applied in the drawing direction. For this reason, if the flap 12f is provided at the center of the front plate 12 with about 1/3 of the entire length of the front plate 12 in the axial direction D, the lid 20 is closed and the centroid of the lid front plate 22 is When pressed, it is conceivable that a gap is formed between the front plate 12 and the lid front plate 22 at a portion outside the flap 12f. In this case, the wrap film 91f corresponding to a portion outside the flap 12f may be cut while sliding (while being pulled out) with respect to the container 1 according to the tension in the pulling direction. As a result, it may occur that the cutting line of the wrap film 91 f does not become a cut edge corresponding to the cutting blade 23. Alternatively, even if the flap 12f is continuously formed with a length substantially the same as the entire length of the front plate 12 in the axial direction D, the lid 20 is closed and the centroid of the lid front plate 22 is pushed. When the center portion of the flap 12f is pushed, both outer portions of the flap 12f sink so as to approach the reinforcing plate 31, and as a result, between the front plate 12 and the lid front plate 22 at the outer portion. It is conceivable that there will be a gap in the gap. In this case, the wrap film 91f corresponding to the portion where the gap is formed is cut while sliding with respect to the container 1 according to the tension in the pull-out direction. As a result, it may occur that the cutting line of the wrap film 91 f does not become a cut edge corresponding to the cutting blade 23.

  On the other hand, in the container 1 according to the present embodiment, the flap 12f is divided into a left flap 12fA and a right flap 12fB, and is provided independently on both sides of the central region 12t. For this reason, when the lid part 20 is closed and the centroid of the lid front plate 22 is pushed, it is possible to prevent the flap 12f from being sunk so as to approach the reinforcing plate 31. As a result, the drawn wrap film 91f can be sandwiched between the flap 12f and the lid front plate 22, and slippage when the wrap film 91f is cut can be suppressed. Furthermore, in the container 1, since the stopper 12s is formed over the entire length of the flap 12f in the axial direction D, the wrap film 91f sandwiched between the flap 12f and the lid front plate 22 moves (slides) in the pull-out direction. Can be stopped. This makes it possible to cut the wrap film 91f more appropriately.

  Since the wrap film 91f sandwiched between the flap 12f and the lid front plate 22 after being cut is attached to the stopper 12s, it is prevented from being rewound onto the wrap roll 91r. Further, when the wrap film 91 f is used next time, the flap 12 f floats outside the main body 10 when the lid 20 is opened. For this reason, the front end of the wrap film 91f adhering to the stopper 12s formed on the flap 12f is also lifted from the front plate 12 outside the flap 12f, and can be easily picked. In particular, in the container 1 according to the present embodiment, since the flap 12f is not formed in the central region 12t, a gap is formed between the central region 12t and the wrap film 91f. The wrap film 91f can be easily picked by inserting.

  As described above, according to the wound body-containing container 100, the wrap film 91f can be sandwiched between the flap 12f and the lid front plate 22 when the wrap film 91f is cut. For this reason, the movement (slip) of the wrap film 91f in the pull-out direction can be stopped even outside the central region 12t, and thus the wrap film 91f can be appropriately cut.

  Further, according to the present embodiment, the container 1 is provided with the fixing piece 17 for preventing the wrap roll 91r from jumping out. The fixed piece 17 is bent with respect to the reinforcing plate 31 with a crease line 17r formed in the reinforcing plate 31 as a rotation axis. As described above, the fold line 17r of the fixed piece 17 is optimally set so that the fixed piece 17 is appropriately bent along the fold line 17r. Therefore, as described above, even when the flap 12f is divided into the left flap 12fA and the right flap 12fB and is provided independently on both sides of the central region 12t, the fixed piece having a desired arrangement and orientation is provided. 17 can be obtained.

  In addition, in the above-mentioned form, the winding body accommodated in the container 1 showed the example which is the wrap roll 91r by which the wrap film 91f was wound. However, the example of the wound body accommodated in the container 1 is not limited to the wrap roll 91r. For example, the container 1 may be used to accommodate a wound body made of an aluminum sheet or a cooking sheet.

  Hereinafter, the present invention will be described in more detail with reference to examples. In addition, this invention is not limited to this Example.

  The length of the joint at the lower fold line 17rb of the fold line 17r of the fixed piece 17 is changed, and the value of the deviation Δh between the upper edge of the side plate 15 and the upper edge 17c of the fixed piece 17 at that time is changed. evaluated. Specifically, first, a fixing piece 17 as shown in FIG. 6 was prepared. Next, the length of the third joint portion CPc of the lower edge side crease line 17rb is 0.0 mm, 0.5 mm, 0.7 mm, 1.0 mm, 1.3 mm, 1.6 mm, or 2.0 mm as described above. The value of Δh was evaluated. At this time, the length of the third fracture portion BPc is changed to 4.5 mm, 4.0 mm, 3.8 mm, 3.5 mm, 3.2 mm in accordance with changing the length of the third joint portion CPc as described above. , 2.9 mm or 2.5 mm. On the other hand, the lengths of the first joint portion CPa, the first fracture portion BPa, the second joint portion CPb, and the second fracture portion BPb are constant values of 2.5 mm, 3.5 mm, 2.0 mm, and 3.5 mm, respectively. did. It is constituted by the length of the upper edge side crease line 17ra constituted by the first joint CPa, the first fracture part BPa and the second joint part CPb, and the second fracture part BPb, the third joint part CPc and the third fracture part BPc. The length of the lower edge side crease line 17rb was always 8.0 mm.

The evaluation of measuring Δh by changing the length of the third joint portion CPc as described above was carried out with n numbers of 10. The results are shown in FIG. 10 as a table and shown in FIG. 11 as a graph. As shown in FIGS. 10 and 11B, when the length of the third joint portion CPc of the lower edge side crease line 17rb is 1.6 mm or less, the deviation Δh is within the range of −0.2 mm to +0.2 mm ( could be in the range) indicated by arrow R _1. On the other hand, when the length of the third joint portion CPc of the lower edge side crease line 17rb is 2.0 mm, the deviation Δh is outside the range of −0.2 mm to +0.2 mm. When the length of the third joint portion CPc is 2.0 mm, the bendability of the lower edge side crease line 17rb cannot be made sufficiently high, and as a result, the left fixed piece 17A has been bent at an unintended location. Conceivable.

In FIG. 11, an approximate straight line generated with respect to the point of the measurement result when the length of the third joint portion CPc is 0.0 mm to 1.3 mm is indicated by a symbol L ₁ , and the third joint portion CPc. the length of the approximate line was generated is shown at _{L 2} for points of measurement results in the case of 1.3Mm～2.0Mm. As apparent from FIG. 11, the gradient of the straight line L ₁ is made significantly smaller than the gradient of the straight line L _2. As a result, when the length of the third joint portion CPc is 0.0 mm to 1.3 mm, the deviation Δh is stably within the range of 0.0 mm to +0.2 mm (the range indicated by the arrow R ₂ ). Yes. Therefore, by setting the length of the third joint portion CPc of the lower edge side crease line 17rb to 1.3 mm or less, even if the length of the third joint portion CPc is slightly deviated from the design, it is stable. Thus, it can be said that the absolute value of the deviation Δh can be reduced.
