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.

  As a structure of the cutting blade, a structure that forms a straight line extending in the axial direction of the wound body and a structure that forms a V shape with the center in the axial direction of the wound body as a vertex are generally known. When cutting a film using a V-shaped cutting blade, use one hand to grasp the tip of the film, pull out the film from the wound body by the required amount, and use the other hand to hold the container in the longitudinal center of the container. Close the part. At this time, the lid front plate of the lid portion is pushed toward the main body portion side of the container with the other hand, whereby the film is sandwiched between the lid front plate of the lid portion and the main body portion, and the film pulled out during this time Twist the container to bite the cutting blade. Thus, a film can be cut | disconnected (for example, refer patent document 1).

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1A to 4. 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. 1B and 4). 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.

(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 has a flap 12 f configured so that a wrap film 91 f drawn from the wrap roll 91 r can be sandwiched between the front plate 22 of the lid 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. 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.

  In the present embodiment, the left flap 12fA 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 addition, a score line formed in the front plate 12 to cut the left flap 12fA extends until reaching the upper edge 19 of the front plate 12 or in the vicinity of the upper edge 19. In this case, the left flap 12fA can rotate with the upper edge 19 of the front plate 12 as the upper edge.

  In FIG. 2, a contour located below the upper edge 19 in the contour of the left flap 12fA is represented by reference numeral 12fAc. In FIG. 2, the cut line remaining on the front plate 12 after the left flap 12fA is cut and raised is indicated by reference numeral 12cA. As shown in FIG. 2, the outline 12fAc of the left flap 12fA extends over the entire area along the front plate 12 after the left flap 12fA is cut, that is, along the cut line 12cA remaining on the front plate 12. ing.

  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 contour 12fAc of the left flap 12fA constituted by the lower side (tip end side) of the left flap 12fA is temporarily raised when it goes from the central region 12t side in the axial direction D to the left side plate 15A side. It has a smooth curved shape with excellent design properties, such that it approaches the edge 19 side and then leaves the upper edge 19 again. 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.

  By the way, as described above, the outline of the flap 12f extends along the front plate 12 after the flap 12f is cut and raised, that is, along the cut lines 12cA and 12cB remaining on 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, a convex region 32 that faces the inner surface of the flap 12f when the lid portion 20 is closed is formed on the outer surface of the reinforcing plate 31. . The convex region 32 is a convex portion 32a that protrudes outward from the outer surface of the reinforcing plate 31, and includes a convex portion 32a that can come into contact with the inner surface of the flap 12f. 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 “inner surface” is a surface formed on the container 1 and facing the accommodation space for accommodating the wound body, and the “outer surface” is a surface opposite to the inner surface, That is, it is the surface opposite to the surface facing the accommodation space. About the reinforcement board 31, the exposed surface which can be visually recognized by the user is an inner surface facing the accommodation space side, and the surface facing the flap 12f and the front plate 12 on the side opposite to the exposed surface is the outer surface. It has become.

  The method for forming the convex portion 32a of the convex region 32 is not particularly limited, and various methods can be adopted. For example, the embossing is performed on the inner surface of the reinforcing plate 31, whereby the convex portion 32 a can be formed on the outer 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 32a.

  As long as the flap 12f can be prevented from fitting into the front plate 12, the shape and arrangement of the convex region 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 convex region 32 including a plurality of convex portions 32 a may be formed so as to be able to intermittently contact the flap 12 f over substantially the entire area of the flap 12 f in the axial direction D.

  Preferably, the convex portion 32a of the convex region 32 corresponds to the corner portions 12fN and 12fS of the left flap 12fA and the corner portions 12fN and 12fS of the right flap 12fB of the outer surface of the reinforcing plate 31, as shown in FIGS. It is formed at least in the portion to be. As a result, the flap 12f can be effectively prevented from fitting into the front plate 12. Here, the corner portions 12fN and 12fS are portions of the flap 12f whose contours are largely bent. In the example shown in FIG. 2, the corner portions 12 fN and 12 fS are portions between a portion extending away from the upper edge 19 and a portion extending substantially along the upper edge 19 in the flap 12 f. In the present embodiment, the corners 12fN and 12fS of the flap 12f can be defined as follows.

In FIG. 2, the distance from the upper edge 19 to the contour 12fAc of the left flap 12fA is maximized, and the point near the central region 12t is represented by reference numeral 12cAN ′. First, a straight line L _N0 that connects the end point 12cAN near the central region 12t of the left flap 12fA and the maximum point 12cAN ′ is generated. Next, a straight line L _N1 that is parallel to the straight line L _N0 and is in contact with the contour 12fAc of the left flap 12fA is generated. In FIG. 2, the point where the straight line L _N1 is in contact among the points on the contour 12 f Ac of the left flap 12 f A is indicated by the symbol P _N. For example, of the left flap 12Fa, the portion in the vicinity of the thus contact _{P N} which is generated, can be defined as a corner 12fN the central region 12t side of the left flap 12Fa. The corner 12fS near the left side plate 15A of the left flap 12fA is similarly defined. That is, initially, to generate a straight line LS ₀ connecting the end points 12cAS and maximum point 12cAS the left side plate 15A nearer ', then a straight line parallel to the straight line LS _0, the contact _{P S} to the contour 12fAc the left flap 12fA A straight line LS ₁ that is in contact with is generated. The portion in the vicinity of the contact point _{P N} is defined as a corner 12 Fs. Similarly, for the right flap 12fB, a corner 12fN near the central region 12t and a corner 12fS near the right side plate 15B are defined.

(Presser plate)
In order to prevent the wrap roll 91r from jumping out, the fixing piece 17 provided in the vicinity of the side plate 15 has been described. However, the member for preventing the wrap roll 91r from jumping out is not limited to the fixed piece 17, and other members may be provided in the container 1. For example, as shown in FIGS. 1B and 3, a holding plate 33 that extends into the container 1 and protrudes toward the wrap roll 91 r may be provided in the container 1.

  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). . Each pressing plate 33A, 33B may be provided so as to at least partially overlap each flap 12fA, 12fB when viewed from the horizontal direction. 2 and 3 show examples in which the pressing plates 33A and 33B are configured so that the entire pressing plates 33A and 33B overlap the flaps 12fA and 12fB when viewed from the horizontal direction.

  As shown in FIG. 1B and FIG. 3, each pressing plate 33 </ b> A, 33 </ b> B 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. In addition, the cut line 33c formed in the reinforcing plate 31 to cut and raise the holding plates 33A and 33B reaches the upper edge of the reinforcing plate 31, that is, the upper edge 19 of the front plate 12, or the upper edge 19 It extends to the vicinity. In this case, each pressing plate 33A, 33B can rotate with the upper edge 19 of the front plate 12 as the upper edge.

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. 4 is a plan view showing an example of a paperboard 50 for producing the container 1.

  In the paperboard 50 shown in FIG. 4, 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.

  The method for producing the paperboard 50 shown in FIG. 4 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. Thereafter, each ruled line, the convex region 32 (or the concave portion 32a), and the like are formed on the paperboard 50 by embossing the paperboard 50 or the like.

  The method for producing the container 1 by forming the paperboard 50 is not particularly limited, and various methods can be used.

  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.

  In the present embodiment, as described above, the flap 12f has a central portion that is recessed closer to the upper edge 19 than both end portions. For this reason, the outline 12 f Ac of the flap 12 f is non-parallel to the cutting blade 23 that extends linearly from the end of the container 1 toward the central portion of the container 1. For this reason, compared with the case where the flap extends in parallel with the cutting blade 23, when the lid portion 20 is closed after the wrap film 91f is pulled out by a necessary amount, the wrap film 91f and the lid front plate 22 of the lid portion 20 The frictional force generated between them can be reduced. Accordingly, it is possible to simultaneously support the wrap film 91f appropriately by the flap 12f and to easily close the lid portion 20.

  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 pressing plate 33 for preventing the wrap roll 91r from jumping out. The holding plate 33 is formed by cutting and raising a part of the reinforcing plate 31. Further, the pressing plate 33 can be rotated about the upper edge 19 of the front plate 12 as a rotation axis, like the flap 12f. For this reason, when pushing the centroid of the lid front plate 22 to cut the wrap film 91f, the flap 12f is rotated toward the inside of the container 1 with the upper edge 19 as the rotation axis, and at the same time the upper edge 19 is rotated as the rotation axis. As described above, the holding plate 33 can be rotated toward the inside of the container 1. That is, since the flap 12f and the pressing plate 33 have a common rotation axis, the flap 12f and the pressing plate 33 can be interlocked. Thereby, it is possible to simultaneously realize the sandwiching of the wrap film 91f between the flap 12f and the lid front plate 22 and the protrusion of the pressing plate 33 toward the wrap roll 91r. This can more reliably prevent the wrap roll 91r from jumping out when the wrap film 91f is cut. As described above, when the pressing plates 33A and 33B are configured so that the entire pressing plates 33A and 33B overlap the flaps 12fA and 12fB when viewed from the horizontal direction, the flaps 12f and the pressing plates 33 are separated from each other. The degree of interlocking can be made higher.

  By the way, when the flap 12f and the pressing plate 33 are interlocked as described above, it is considered that the flap 12f easily rotates toward the reinforcing plate 31. This is because when the flap 12f is rotated about the upper edge 19 so that the flap 12f approaches the reinforcing plate 31, the elastic resistance force acting on the flap 12f from the reinforcing plate 31 causes the pressing plate 33 to rotate. It is because it is eased by moving. The fact that the flap 12f easily rotates toward the reinforcing plate 31 means that the flap 12f can easily approach the cut lines 12cA and 12cB of the front plate 12. Even in such a case, according to the present embodiment, the convex region 32 facing the inner surface of the flap 12f is formed on the outer surface of the reinforcing plate 31 as described above. For this reason, when the convex part 32a of the convex area | region 32 contacts the inner surface of the flap 12f, it can prevent that the flap 12f fits into the front plate 12. FIG. Therefore, according to the present embodiment, it is possible to simultaneously improve the cutting property of the wrap film 91f by the flap 12f and prevent the wrap roll 91r from popping out by the pressing plate 33.

  In the present embodiment, an example is shown in which the convex region 32 formed on the reinforcing plate 31 includes five convex portions 32a configured to face the inner surface of the flap 12f. However, the specific form of the convex region 32 is not particularly limited. For example, the convex region 32 may include four or less convex portions 32a, or may include six or more convex portions 32a. In any case, the convex region 32 preferably includes a convex portion 32a formed in a portion corresponding to the corner portions 12fN and 12fS of the flap 12f. As a result, the flap 12f can be effectively prevented from fitting into the front plate 12.

  Moreover, as shown in FIG. 5, the convex area | region 32 may be comprised from the one convex part 32a extended in the longitudinal direction of the container 1 corresponding to the flap 12f. It should be noted that embossing for forming the protrusions 32a on the paperboard 50 is generally performed on the paperboard 50 with cut lines such as the cut lines 12cA and 12cB for the flaps 12f and the cut lines 33c for the pressing plate 33. Implemented after forming. The cut line is configured as a perforation, for example. Then, the container 1 is produced by bending the paperboard 50 along a ruled line or a crease line. Here, if the size per one convex portion 32a is large, when embossing for forming the convex portion 32a on the paperboard 50 is performed, a cut line already formed on the paperboard 50, for example, a cut line 33c, is formed. May break. If the score line breaks during embossing, the member is cut and raised along the score line, and as a result, the subsequent folding process may be hindered. Therefore, in consideration of the embossing process and the subsequent bending process, it is preferable that the size of each protrusion 32a is small. That is, as shown in FIG. 3, it is preferable that the convex region 32 includes a plurality of convex portions 32a.

  Moreover, in this Embodiment, the outline 12fAc and 12fBc of the flap 12f showed the example extended along the front plate 12 after the flap 12f was cut and raised over the whole region. That is, an example is shown in which the outlines 12fAc, 12fBc of the flap 12f and the cut lines 12cA, 12cB remaining on the front plate 12 after the flap 12f is cut and raised coincide with each other. However, as shown in FIG. 6, the outlines 12fAc and 12fBc of the flap 12f may not coincide with the cut lines 12cA and 12cB remaining on the front plate 12 after the flap 12f is cut and raised. The cut lines 12cA and 12cB of the front plate 12 as shown in FIG. 6 can be realized by cutting out other portions adjacent to the flap 12f from the front plate 12 in addition to the flap 12f. As described above, the contours 12fAc, 12fBc of the flap 12f and the contour of the front plate 12 are partially mismatched, so that the possibility that the flap 12f fits into the front plate 12 can be reduced. In the form shown in FIG. 6, more reinforcing plates 31 are exposed to the outside by cutting out a part of the front plate 12 more than in the form shown in FIG. For this reason, in consideration of design, it is preferable that the contours 12fAc and 12fBc of the flap 12f and the contours of the front plate 12 coincide as shown in FIG.

  Moreover, in this Embodiment, the outline 12fAc and 12fBc of the front plate 12 showed the example which has a smooth curvilinear shape. However, as shown in FIG. 7, the contours 12fAc and 12fBc of the front plate 12 may have a linearly extending portion. In this case, the corners 12fN and 12fS of the flap 12f are defined as portions corresponding to the boundary between the curvedly extending portion and the linearly extending portion of the flap 12f.

  Moreover, in this Embodiment and the modification, the example in which the convex area | region 32 for preventing the flap 12f fitting in the front plate 12 was formed in the outer surface of the reinforcement board 31 was shown. However, the present invention is not limited to this, and a convex region (not shown) that faces the outer surface of the reinforcing plate 31 when the lid portion 20 closes the opening of the main body portion 10 is formed on the inner surface of the flap 12f. Also good. Similarly to the case of the present embodiment and the modification, the convex region formed on the inner surface of the flap 12f also includes a convex portion that protrudes from the inner surface of the flap 12f toward the inside of the container 1. For this reason, it can prevent that the flap 12f fits into the front plate 12. Preferably, the convex region formed on the inner surface of the flap 12f is formed at least at the corners 12fN and 12fS of the flap 12f on the inner surface of the flap 12f. As a result, the flap 12f can be effectively prevented from fitting into the front plate 12.

  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.
