Winding body storage box and storage box with winding body

The present invention relates to a wound body storage case and a storage case containing the wound body, and more particularly to a wound body storage case and a storage case containing the wound body which can prevent the wound body from falling out.

It is widely used for food wraps for foods such as ingredients, dishes, dishes, and the like. The plastic wrap for food is typically a long plastic film (rolled body) wound in a roll shape and stored in a long rectangular parallelepiped container (storage box). When used, the film at the front end is self-rolled. The cartridge is pulled out of the required amount and cut with a cutting blade attached to the lid of the container. The wrap film for food has the following disadvantages: when the film is pulled out from the reel, the reel itself falls out of the container. As a technique for eliminating such an inconvenience, there is a leading edge of the side panel before the storage box, and a guide wing having a protruding amount slightly larger than one-half of the length of one side of the end panel is connected via a folding line (for example, reference) Patent Document 1).

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or similar reference numerals are given to the same or corresponding components, and the description thereof will be omitted.

First, with respect to Fig. 1, a wrap film cassette 1 as a wound body storage case and a wrap film roll 91r as a wound body in a wrap film holder 1 according to an embodiment of the present invention are described as being equipped with a winding. A carton 100 containing a plastic wrap for the storage box of the body. Fig. 1(A) is a perspective view of a carton 100 containing a cling film, and Fig. 1(B) is a side cross-sectional view of a carton 100 containing a cling film. Fig. 1(A) shows the open state. The cling film reel 91r is formed by winding a wrap film 91f as a film-like elongate object around a cylindrical winding core around an axis to form a roll. In the present 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 film cassette 1 includes a main body portion 10 that houses the wrap film roll 91r, a lid portion 20 that is connected to the main body portion 10, and a pressure plate 30 that is connected to the main body portion 10.

The main body portion 10 is a case in which one of the elongated faces is formed as an opening face 10h in a rectangular parallelepiped that can accommodate an unused wrap roll 91r. Regarding the size of the body portion 10, one In the present embodiment, the gap is formed as small as possible so as not to prevent the unused wrap roll 91r from rotating around the axis. In the present embodiment, the width is 44 mm, the height is 44 mm, and the length is 310 mm. The main body portion 10 has a side surface of the front plate 12, the bottom plate 13, the rear plate 14, and one end surface constituting the rectangular parallelepiped, which cooperate with the opening surface 10h and constitute a 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 10h and the bottom plate 13. The side plates 15 are typically formed in a square shape, but may be rectangular in which the lengths of the vertical and horizontal directions are different. A projection 15p formed by folding a small piece extending upward by about 3 mm to the outside is provided at a central portion of the upper end side 15s of the side plate 15 at 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. In the following description, the state in which the bottom plate 13 is placed on the horizontal surface is used as a reference, and the side of the bottom plate 13 is referred to as the lower side and the opening surface 10h side as the upper side.

The lid portion 20 is a member that closes the opening surface 10h by fitting the body portion 10 to the outside. The lid portion 20 has a cover plate 21, a cover sheet 22, a cutting blade 23, and a side cover sheet 25. The cover plate 21 is a rectangular flat member slightly larger than the opening surface 10h, and can be a rectangular parallelepiped of the plug body portion 10 by overlapping the cover plate 21 and the opening surface 10h. The fact that the cover 21 is slightly larger than the opening surface 10h means that the cover 21 is larger than the thickness of the cover sheet 22 and the thickness of the side cover sheet 25, and the large formation does not hinder the opening and closing of the cover portion 20. The extent of the gap. One of the longitudinal directions of the cover plate 21 is connected to the rear end edge 18 of the body portion 10. In other words, the body portion 10 and the cover plate 21 are connected via the rear plate end edge 18. The rear plate end 18 is the end of the plate 14 after the portion where the rear plate 14 intersects the opening face 10h. The cover plate 21 is configured to be rotatable relative to the body portion 10 with the rear plate end edge 18 as a rotational axis.

The cover sheet 22 is disposed to be orthogonal to the cover 21 via the bent side 21f, and extends toward the bottom plate 13 when the cover portion 20 is closed. The height of both ends of the mask sheet 22 in the direction in which the axis of the wrap film roll 91r extends (hereinafter referred to as "axis direction D") (the length in the short side direction of the rectangular front plate 12) is the short side direction of the front plate 12. The length is about 1/2, and the height of the central portion in the axial direction D is about 3/4 of the length of the short side direction of the front plate 12. Before the bend edge 21f The end edge 22t is formed such that the distance between the bent side 21f and the front end side 22t in the direction orthogonal to the axial direction D becomes shorter as it moves from the center of the axial direction D to the respective end portions. According to this configuration, the front end 22t is formed in a V shape with respect to the bent side 21f. The cover sheet 22 overlaps the outer side of the front panel 12 along the front panel 12 when the lid portion 20 is closed, and covers the upper portion of the front panel 12 in a pentagonal shape. The length of the mask sheet 22 in the axial direction D is slightly longer than that of the front panel 12, and is longer than the width of the wrap film 91f housed in the body portion 10. Thereby, the masking sheet 22 is configured such that the wrap film 91f pulled out from the body portion 10 can be sandwiched between the mask sheet 22 and the front panel 12 over its entire width. A cutting blade 23 for cutting the wrap film 91f is attached to the front end 22t of the cover sheet 22. The cutting blade 23 is provided in a V shape along the front end side 22 so that the blade edge protrudes from the front end side 22t.

The side cover piece 25 is disposed orthogonally to both the cover plate 21 and the cover sheet 22. The side cover sheets 25 are provided in total at two ends of the cover plate 21 (covering sheet 22). The basic shape of the side cover sheet 25 is such that the long side is the same length as the short side of the cover plate 21, and the height of the short side and the central portion of the cover sheet 22 (the shortest distance from the V-shaped front end to the bent side 21f) is Rectangles of approximately the same length. The side cover piece 25 is formed by removing the corners at the side of the bottom plate 13 side and the side of the rear plate 14 side based on the basic shape. The side cover piece 25 is fixed to the joining piece 22j connected to the masking piece 22 with an adhesive. A recess 25d is formed between the engaging piece 22j and the cover 21 on the inner side of the side cover piece 25. In the recessed portion 25d, when the lid portion 20 is closed, a projection 15p provided at the upper end of the side panel 15 is fitted. The cover portion 20 constructed as described above covers the opening 10h of the body portion 10 when closed, and the cover sheet 22 covers the upper portion of the front panel 12.

The pressure plate 30 prevents the wrap film reel 91r housed in the main body portion 10 from falling out of the main body portion 10 by covering the opening surface 10h of the main body portion 10. The platen 30 has a cover plate 31 and an insert piece 32 (see Fig. 1(B)). The superposed plate 31 is a rectangular flat member slightly smaller than the opening surface 10h, and is connected to the front end 19 of the main body portion 10 in the present embodiment. The front end edge 19 is a portion of the front side of the front panel 12 where the front panel 12 and the opening surface 10h intersect. The side of the cover panel 31 that is joined to the front end edge 19 is referred to as the splice edge 39. In this embodiment, the front end edge 19 is also connected. End edge 39. The cover plate 31 is slightly smaller than the opening face 10h, and when the cover plate 31 is rotated with the joint end edge 39 as the rotation axis, the cover plate 31 is in a state of being small enough to enter the body portion 10.

The cover plate 31 is formed with a slit-shaped pull-out port 31s which is elongated in the axial direction D. The length of the pull-out port 31s in the axial direction D is formed to be substantially the same as the width of the wrap film 91f accommodated in the main body portion 10 in a state of being wound around the winding core. At this time, if the length of the axial direction D of the pull-out port 31s is slightly larger than the width of the wrap film 91f, the resistance against the sheathing plate 31 when the wrap film 91f is pulled out can be eliminated, which is preferable. Further, in order to prevent the wrap film roll 91r housed in the main body portion 10 from moving in the axial direction D, the length of the core of the wrap roll 91r is formed to be slightly shorter than the inner size of the main body portion 10, and The wrap film 91f is wound around the winding core so that the end portion in the axial direction D of the wrap film 91f wound around the winding core is wound on the inner side of the end portion of the winding core by about 3 to 5 mm, and the wrap film 91f is wound. It is preferred because the position relative to the pull-out port 31s is relatively stable. The central portion of the axial direction D of the pull-out port 31s is an expanded portion 31sE which is wider in the direction orthogonal to the axial direction D than both ends thereof. The expansion portion 31sE is formed in such a size that a finger can be inserted into the body portion 10 through the pull-out port 31s from the outer side of the body portion 10, and the front end of the wrap film 91f wound up as the wrap film roll 91r can be pinched and pulled out. Outside the body portion 10. The pull-out port 31s is formed in the vicinity of the opposite end edge 38 such that the area of the cover plate 31 becomes larger between the opposite end edge 38 and the pull-out port 31s than between the opposite end edge 38 and the pull-out port 31s.

The insertion piece 32 is a member provided to stabilize the position of the cover plate 31 covering the opening face 10h. The insertion piece 32 is connected to the end edge 38 of the cover plate 31 opposite to the continuous end edge 39, and is opposite to the cover plate 31 in such a manner as to enter the body portion 10 when the cover plate 31 covers the opening face 10h. Set the place. Since the insertion piece 32 is provided along the main body portion 10, the orthogonality herein also includes substantially orthogonality which is close to orthogonal but not strictly orthogonal. The height of the insertion piece 32 (the distance orthogonal to the axial direction D) is self-cleaning film cassette 1 from the viewpoint of stabilizing the cover sheet 31 during use, and in the manufacture of the paper cassette 100 containing the wrap film. When the end surface is inserted into the wrap film roll 91r, it is preferable to prevent the insertion of the wrap film roll 91r from being disturbed, and the height is equal to the height of the rear plate 14, but the attachment and detachment of the insert piece 32 is easy. From the viewpoint of the saving of the member, it is preferably about 1/4 to 1/2 of the height of the rear plate 14, and preferably about 1/3 of the height of the rear plate 14. However, it is also possible to form a size other than the size of the wrap film cassette 1 or the characteristics of the wrap film 91f stored therein. The cover plate 31 and the insert piece 32 are typically configured to be distinguished by bending one plate-like member at the opposite end 38. When the cover sheet 32 covers the opening surface 10h, the insertion piece 32 is provided along the rear plate 14 of the main body portion 10 in the present embodiment. At this time, at least a portion (preferably a face) of the insertion piece 32 may be disposed in contact with the rear plate 14. According to this configuration, the frictional force of the insertion piece 32 with respect to the rear plate 14 can suppress the opening of the cover plate 31 to the outside. On the other hand, the insertion piece 32 is detachably disposed without being directly connected to the main body portion 10. When it is desired to take out the wrap film reel 91r housed in the main body portion 10, the continuous end side 39 can be used as The platen 30 is opened to the outside by the rotation axis, so that the wrap roll 91r is easily taken out from the body portion 10.

As shown in the expanded view of Fig. 2, the main body portion 10, the lid portion 20, and the pressure plate 30 are integrated as a material before assembly in the present embodiment. The wrap film cassette 1 is formed by processing a cardboard having a thickness of about 0.45 to 0.7 mm. Therefore, the wrap film cassette 1 has elasticity. That is, in the present embodiment, for the sake of convenience of description, the main body portion 10, the lid portion 20, and the pressure plate 30 are distinguished from the viewpoint of function, but the main body portion 10, the lid portion 20, and the pressure plate 30 are cut into a base paper and assembled. And formed into one. The surface of the main body portion 10 and the lid portion 20 is subjected to surface treatment as a whole after the printing is designed to cause the consumer's desire to purchase.

As shown in FIG. 2, in the front plate 12, the joining piece 12j is connected to the both ends of the axial direction D. In the rear plate 14, a joint piece 14j is connected to both ends of the axial direction D. The two side plates 15 are respectively connected to both ends of the bottom plate direction D of the bottom plate 13. The insertion piece 32, the cover sheet 31, the front plate 12, the bottom plate 13, the rear plate 14, the cover plate 21, and the cover sheet 22 are arranged in this order, and the adjacent members are integrally connected to each other in the axial direction D. Further, on the outer side of the cover sheet 22, through the perforation line A cut piece 29 is attached to the 29c. In the cover plate 21, side cover sheets 25 are connected to both ends of the axial direction D. In the mask sheet 22, a joint piece 22j is connected to both ends of the axial direction D. In the two engaging pieces 14j, a locking hole 17 is formed in the vicinity of the rear plate 14 and the side cover piece 25.

The insertion piece 32, the cover plate 31, the front plate 12, the bottom plate 13, and the rear plate 14 are bent at a bending line extending in the axial direction D, and the engaging piece 12j, the engaging piece 14j, and the side plate 15 are respectively in the axial direction D The bending line extending in the direction orthogonal to the boundary is bent, and the main body portion 10 and the rectangular parallelepiped body portion 10 are formed by overlapping the joining piece 12j on the outer side of the joining piece 14j and overlapping the side plate 15 on the outer side of the joining piece 14j. The pressure plate 30 of the opening face 10h. Further, the rear plate 14, the cover plate 21, and the cover sheet 22 are bent at a bending line extending in the axial direction D, and the side cover sheets 25 and the engaging pieces 22j are respectively bent in a direction orthogonal to the axial direction D. The fold line is bent, and the side cover piece 25 is superposed on the outer side of the joint piece 22j as described above, thereby forming the three-dimensional cover portion 20. When the wrap film cassette 1 is assembled from the material as described above, the locking holes 17 are formed on both end faces of the inner side of the main body portion 10 on the inner side of the side plate 15.

In Fig. 3, the structure around the locking hole 17 is shown. Fig. 3(A) is a partial perspective view showing a state in which the side panel 15 in the middle of the assembly of the wrap film cassette 1 is opened, Fig. 3(B) is a partial perspective view showing the inner side of the main body portion 10, and Fig. 3(C) is a cling film tray. Partial horizontal section of 1 . In Fig. 3(B), the cover portion 20 is omitted for convenience of explanation. In the present embodiment, since the side plate 15 is provided, the locking hole 17 does not penetrate the main body portion 10 and becomes a recess. The length of the axial direction D of the portion corresponding to the height of the locking hole 17 at both ends of the insertion piece 32 in the axial direction D is formed to be larger than the inner size of the main body portion 10 by a thickness of substantially two pieces of the engaging piece 14j (refer to the figure). 3(C)). According to this configuration, when the insertion piece 32 is disposed inside the main body portion 10, the insertion piece 32 can be engaged with the locking hole 17. In the present embodiment, the insertion piece 32 and the locking hole 17 constitute a locking portion.

When the manufacturing place of the wrap film cassette 1 is different from the manufacturing place of the carton 100 containing the wrap film, the wrap film cassette 1 is typically placed in a flat folded state as follows, and is placed in a wrap film. The manufacturing site of the carton 100 is transported: in the expanded view shown in Figure 2. As seen, between the cover plate 31 and the front plate 12, between the bottom plate 13 and the rear plate 14, and between the cover plate 21 and the cover sheet 22, respectively, and the cover plate 21 is superposed on the cover plate 31 and The rear plate 14 is superposed on the insertion piece 32, and after the cover piece 22 and the cut piece 29 are superposed on the front plate 12, the cut piece 29 is attached to the front plate 12 at a plurality of points. The wrap film cassette 1 in a folded state is in a state in which the side plates 15 and the respective engaging pieces 12j, 14j, and 22j are not joined. In the case of the plastic wrapper 1 in a folded state, each of the joining pieces 12j, 14j, and 22j is peeled off from the wrap film case 1 to be flat. However, in order to improve the manufacturing efficiency, it is generally manufactured so as not to be assembled and folded. . In this case, since the original meaning is exhibited in the assembled state, the folded wrap film cassette 1 can also be regarded as one of the cling film cassettes 1.

In the manufacturing place of the paper box 100 in which the plastic wrap is placed, the folded wrap plastic paper cassette 1 is first formed into a rectangular tubular shape with both ends open, and the self-adhesive film roll 91r is inserted from one end surface, and the joining piece 14j and the engaging piece are used. 12j, the side plate 15, the engaging piece 22j, and the side cover piece 25 are sequentially bent, and the joining piece 14j, the joining piece 12j, and the side plate 15 are mutually connected, and the side cover piece 25 is attached to the joining piece 22j, thereby being loaded. There is a plastic wrapper 100. At this time, when the insertion piece 32 is attached to the rear plate 14, when the flattened wrap film 1 is raised into a rectangular tubular shape, the insertion opening cover 31 and the insertion of the wrap roll 91r can be prevented. Since the sheet 32 is sealed, it is preferable to prevent the insertion of the wrap film roll 91r into the wrap film cassette 1 from being hindered. Further, when the insertion piece 32 is detachably attached to the rear plate 14, the case where the plastic wrapper 100 is placed, for example, the front end of the wrap film 91f temporarily pulled out into the main body portion 10 is used. When it is desired to open the platen 30, it can be easily opened. Here, the peelable adhesion is generally referred to as a mode in which the original shape of the insert piece 32 and the main body portion 10 is retained even after peeling, without losing its function.

Next, the action of the paper box 100 equipped with the wrap film will be described with reference to FIG. The function of the wrap film cassette 1 will be described as one of the functions of the carton 100 containing the wrap film. The unopened carton 100 containing the wrap film is attached to the front end of the cover sheet 22, and the cut piece 29 (see FIG. 2) is connected via the perforation line 29c (see FIG. 2) on the front end side 22t, and the piece 29 is cut out in plural. Point On the front panel 12. When the wrap film 91f of the carton 100 containing the wrap film is dispensed and delivered to the consumer's hand for the first time, the cut piece 29 is peeled off from the front plate 12 while being cut at the perforation line 29c to separate the self-masking piece 22 Separation. By thus unsealing the wrap film cassette 1, the lid portion 20 is rotatable relative to the main body portion 10 around the rear plate end side 18.

The carton 100 containing the wrap film after the unsealing is provided with the wrap film roll 91r in the main body portion 10, and the opening surface 10h of the main body portion 10 is covered by the cover plate 31 of the press plate 30. On the cling film reel 91r, a pull-out sticker (not shown) is attached to the front end of the wrap film 91f, and the pull-out sticker (not shown) is pulled and pulled out, and the wrap film 91f is self-preserved from the front end. The spool 91r is peeled off, so that the wrap film 91f can be easily pulled out. At this time, since the expansion portion 31sE is formed in the pull-out port 31s of the sheathing plate 31, even if the pressure plate 30 is not opened to the outside to expose the entire opening surface 10h, the self-expanding portion 31sE can be inserted into the body portion 10 by pinching. The cling film 91f is pulled out. Further, the pressure plate 30 may be opened to the outside, and the wrap film 91f may be pulled out, and the front end of the drawn wrap film 91f may be passed through the pull-out port 31s, and then the platen 30 may be closed again to cover the opening surface 10h.

When the wrap film 91f is used, after the lid portion 20 is opened, the wrap film 91f is pulled out from the wrap film roll 91r by a required length and cut by the cutter blade 23. At this time, since the opening surface 10h is covered by the cover sheet 31, and the cover sheet 31 is prevented from opening to the outside by the insertion piece 32 entering the body portion 10 and being engaged, the wrap film roll 91r can be prevented from being implicated by the wrap film 91f. It falls out from the body portion 10. Further, if the lid portion 20 is closed while the wrap film 91f is pulled out to the required length, the front panel 12 and the masking sheet 22 are sandwiched by the wrap film 91f, and the center of the masking sheet 22 is pressed with the thumb, so that When the center of the cutting blade 23 is bitten into and pulled out of the wrap film 91f, the carton 100 containing the wrap film is twisted around the axis, and it is easy to be attached to the tableware or the like to be wrapped with the wrap film 91f. It is more suitable because it is cut off.

After the preservative film 91f to be used is cut, the front end of the wrap film 91f connected to the wrap film roll 91r usually remains between the front plate 12 and the cover sheet 22, but even if it is assumed to fall into the opening face 10h In this case, since it is placed on the cover 31 between the front end edge 19 and the pull-out port 31s, it can be prevented from being rewound and adhered to the wrap roll 91r. When the wrap film 23 is cut by the cutting blade 23, even if the lid portion 20 is cut in a half-open state, the front end of the cut-off wrap film 91f which is connected to the wrap film roll 91r remains on the cover sheet 31. Therefore, it can be prevented from adhering to the wrap roll 91r. Further, in order to prevent the front end of the cut-off wrap film 91f from being rewound to the wrap film roll 91r, a part or all of the front plate 12 or a cover plate 31 may be covered by the portion covered by the cover sheet 22 when the cover portion 20 is closed. The plate 21 is provided with a locking mechanism for attaching the wrap film 91f by applying varnish, attaching a label, or the like in the vicinity of the front plate 12 facing the plate 21. Further, in order to easily pinch the front end of the wrap film 91f, the front plate 12 may be formed on the front plate 12 which is covered by the cover sheet 22 when the cover portion 20 is closed, and the flap in which the front plate end side 19 is suspended as the rotation axis is formed. In this case, the locking mechanism can be placed on the flap.

As described above, in the wrap film cassette 1, the opening surface 10h of the main body portion 10 is covered by the cover sheet 31 of the pressing plate 30, and the insertion piece 32 connected to the cover sheet 31 enters the inside of the main body portion 10 and follows the rear. Since the plate 14 is disposed, when the wrap film 91f is pulled out, even if the wrap film roll 91r is pulled by the wrap film 91f and is to be dropped from the main body portion 10, the wrapper 31 prevents the wrap film roll 91r from falling out. The wrap roll 91r is prevented from falling out of the body portion 10. Further, since the insertion piece 32 is fitted into the locking hole 17, the insertion piece 32 is engaged with the main body portion 10. Therefore, even if the force of the wrap film roll 91r to be dropped from the main body portion 10 acts, the cover plate can be prevented. 31 opens to the outside.

Further, in the case where the insertion piece 32 is detachably attached to the rear plate 14, it is possible to prevent the paper box 100 containing the wrap film from being manufactured in the following order, that is, folding to make the wrap film 1 in the flat state stand up In the case of a rectangular tube shape, and then the wrap film roll 91r is inserted from the end surface of the rectangular tube, the insertion opening cover plate 31 and the insertion piece 32 of the wrap film roll 91r are closed. Further, in the case of manufacturing the paper box 100 containing the wrap film in the above-described order, instead of peeling the insert piece 32 to the rear plate 14, the cover plate 31 and the cover plate 21 may be replaced in the manufacturing stage. Peelable to follow. In this case, the insertion opening cover plate 31 and the insertion piece 32 of the wrap film roll 91r can be prevented from being closed during the manufacturing stage, and are used in the hands of the consumer. At the time of separating the cut piece 29 from the cover sheet 22 and opening the lid portion 20 for the first time, the cover sheet 31 and the lid 21 are peeled off.

In the above description, the pressure plate 30 is connected to the front plate 12, but may be connected to the one side plate 15. In this case, when the cover plate 31 covers the opening face 10h, the insertion piece 32 is disposed inside the body portion 10 along the other side plate 15. Further, in the above description, the pressing plate 30 is integrally formed with the main body portion 10. However, the pressing plate 30 may be formed separately from the main body portion 10, and may be connected to the main body portion 10 close to the opening surface 10h. Upper end. In this case, in addition to the front plate 12 or the side plate 15, it may be connected to the rear plate 14. The pressure plate 30 is formed as an individual independent of the main body portion 10 and is connected to the rear plate 14. When the cover plate 31 covers the opening surface 10h, the insertion piece 32 is disposed inside the main body portion 10 along the front plate 12.

In the above description, the pull-out port 31s is formed in the configuration of the wrap film cassette 1 in which the front end edge 19 is also the splice end edge 39, and the opposite end edge 38 between the splice end edge 39 and the pull-out port 31s is The larger between the pull-out ports 31s is formed in the vicinity of the opposite end edge 38, in other words, in the vicinity of the rear plate 14, but may be formed in the direction orthogonal to the axial direction D at the opposite end 38 and the joint end. In the middle of the side 39, it may be formed in the vicinity of the front panel 12. However, if the pull-out port 31s is formed in the vicinity of the rear plate 14, the area of the cover plate 31 between the front plate end edge 19 and the pull-out port 31s becomes large, and the wrap film 91f which is pulled out from the wrap film roll 91r can be improved. It is preferable that the front end does not rewind to the state in which the wrap film roll 91r is placed on the cover plate 31.

In the above description, the locking portion is slightly longer than the body portion 10 by the length of the locking hole 17 formed in the engaging piece 14j of the rear plate 14 and the height of the locking hole 17 in the axial direction D. The inner size insert piece 32 is configured, but may be configured as follows.

In the form shown in the partial vertical cross-sectional view of Fig. 4(A), the expansion portion 32p bulging outward is formed on both sides of the insertion piece 32 orthogonal to the axial direction D, and the two expansion portions 32p of the insertion piece 32 are interposed therebetween. The length (the distance in the axial direction D) is formed to be the same as or smaller than the inner size of the main body portion 10, and is formed on the engaging piece 14j instead of forming the locking hole 17 (refer to FIG. 3) to be covered by the cover plate 31. The shape of each of the sides of the expansion portion 32p of the insertion piece 32 is sandwiched up and down when the opening surface 10h There are two recesses 14jd recessed toward the inner side of the body portion 10. According to this configuration, even when the insertion piece 32 moves the opposite end 38 (see FIG. 1(A)) as an axis to move toward or away from the main body portion 10, the insertion piece 32 and the main body portion 10 can be maintained. The card is locked so that the card can be stabilized. Further, when the portion between the two concave portions 14jd of the engaging piece 14j is recessed toward the side plate 15 side, the fitting of the portion between the expanded portion 32p and the concave portion 14jd can be further deepened, and the engaging piece 14j can be further reinforced (the main body portion 10) ) the force of engagement with the insertion piece 32.

In the form shown in the partial horizontal cross-sectional view of Fig. 4(B), instead of forming the locking hole 17 (see Fig. 3), the engaging piece 14j is formed at the position of the locking hole 17 (see Fig. 3). The convex portion 14jp projecting inward, and the length of the insertion piece 32 in the axial direction D is larger than the length between the tops of the convex portions 14jp formed on both sides in the axial direction D, and is formed to be smaller than the inner size of the main body portion 10. According to this configuration, the length of the insertion piece 32 in the axial direction D can be made the same as that of the cover plate 31, and the manufacturing is simple.

In the above description, the pull-out port 31s formed in the sheathing plate 31 is a slit shape elongated in the axial direction D, but may be formed as an axis with, for example, the first modification shown in FIG. 5(A). The width in the direction orthogonal to the direction D is a rectangular opening having a width equal to or smaller than the diameter of the core of the wrap roll 91r and having a sufficient width (for example, 15 mm or more), that is, the pull-out port 31sA. If it is formed as the pull-out port 31sA, it is of course possible to prevent the wrap film roll 91r from falling out, and when the front end of the wrap film 91f is rewound, it is easy to pinch the front end of the wrap film 91f and pull it out without opening the cover sheet 31 to the outside. . When the stacking plate 31 is formed with the pull-out port 31sA, the expansion portion 31sE that is expanded in the direction orthogonal to the axial direction D may be provided (see FIG. 1(A)).

Alternatively, as in the second modification shown in FIG. 5(B), the pull-out port formed on the sheathing plate 31 may be configured to cut into the line 31c. The cut-in line 31c mainly extends in the axial direction D with a length substantially the same as the width of the wrap film 91f, and is formed to extend toward the rear plate 14 at both ends thereof. At this time, the broken line 31t of the perforation line or the scribe line is formed so that the front end plate 14 of the joining cut line 31c is bent toward the front end, and the portion of the cover sheet 31 surrounded by the cut line 31c is defined by the fold line 31t as the rotation axis. The other parts float upwards, so that the pull can be reduced The resistance when the cling film 91f is out. When the cover plate 31 is formed with the cut-in line 31c as the pull-out port, the expansion portion 31cE which is expanded in the direction orthogonal to the axial direction D may be formed so that the cut-in line 31c is widened toward the front plate 12 side.
