Embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, the same or similar components are denoted by the same or like reference numerals, and the description thereof will be omitted.

First, an embodiment of the present invention will be described with reference to Fig. 1, and a packaging film cassette 1 as a winding body housing case and a paper cassette 100 containing a packaging film as a winding box of the winding body will be described. Packaging film carton In the 100-series packaging film cassette 1, a packaging film roll 91r as a winding body is housed. Fig. 1(A) is a perspective view of a carton 100 containing a packaging film, and Fig. 1(B) is a plan view of a packaging film carton 1. Fig. 1(A) shows the open state. The wrap film roll 91r is formed into a roll shape by winding a wrap film 91f as a film-shaped long product on a cylindrical core around an axis 91a. The packaging film roll 91r is formed in an elongated shape, and the wrap film 91f is wound and wound in the longitudinal direction, and the outer diameter of the roll shape is smaller than the width 91fw of the wrap film 91f. Therefore, the width direction of the wrap film 91f is the longitudinal direction of the wrapping film roll 91r (the same direction as the direction in which the axis 91a of the wrapping film roll 91r extends, hereinafter referred to as "the axial direction D"). In the following description, the packaging film 91 is collectively referred to as the "packaging film 91" without distinguishing the outer shape of the packaging film roll 91r and the wrap film 91f. In the present embodiment, the wrap film 91f is made of polyvinyl chloride as a raw material to have a thickness of 5 to 20 μm. The packaging film cassette 1 is provided with a main body portion 10 for accommodating the packaging film roll 91r, and a cover portion 20 connected to the main body portion 10.

In the present embodiment, the main body portion 10 is a box in which a rectangular parallelepiped having a size of an unused packaging film roll 91r is placed so that one of the elongated faces becomes the opening face 10h. The main body portion 10 is formed in an elongated shape in the same direction (axial direction D) as the packaging film reel 91r when the packaging film reel 91r is housed. When the body portion 10 forms a gap, it does not hinder the rotation of the unused unused packaging film roll 91r about the axis 91a, and on the other hand, the size thereof is formed as small as possible, and the size of the body portion 10 in the present embodiment. It is formed into a width of 44 mm, a height of 44 mm, and a length of 310 mm. Thus, the packaging film cassette 1 can be sized for one hand. The body portion 10 has a front side plate 12 and a bottom plate formed in cooperation with the opening surface 10h to form a rectangular parallelepiped side surface. 13. The rear plate 14 and the two ribs 15 constituting the end faces 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 10h and the bottom plate 13. The ribs 15 are generally formed in a square shape, but may be rectangular shapes having different longitudinal and lateral lengths. In the following description, the state in which the bottom plate 13 is placed on the horizontal surface is used, and the bottom plate 13 side is downward and the opening surface 10h side is upward.

At a central portion of the upper end of the rib 15 is provided a projection 15p which is formed by folding a small piece extending upward by about 3 mm to the outside. There are two protrusions 15p which are respectively disposed at the upper ends of the individual ribs 15. Further, the body portion 10 has a sub-plate (not shown) provided on the back side of the front plate 12 (inside of the main body portion 10) and connected to the front plate 12 on the front plate end side 19. The front end side 19 is a portion where the front plate 12 and the opening surface 10h intersect each other on the end side of the front plate 12, and in the present embodiment, also serves as a boundary between the front plate 12 and the sub-plate. The size of the sub-plate is slightly the same as that of the front plate 12, but is not in contact with the bottom plate 13, and is disposed closer to the inner side of the body portion 10 than the front plate 12. The end side of the bottom plate 13 end of the sub-plate is bonded to the front plate 12 in the axial direction D.

The cover portion 20 is a member that closes the opening surface 10h of the body portion 10. The cover portion 20 has a cover plate 21, a cover sheet 22, a blade 23, and a side cover sheet 25. The cover plate 21 is a rectangular flat member having a size similar to that of the opening surface 10h. By aligning the cover 21 with the opening surface 10h, a rectangular parallelepiped that closes the body portion 10 can be formed. The size of the cover plate 21 is slightly the same as that of the opening surface 10h, and indicates that the cover plate 21 is increased in size corresponding to the thickness of the cover sheet 22 and the thickness of the side cover sheet 25, and the size thereof can form a gap that does not hinder the opening and closing of the cover portion 20. The extent of it. One side of the axial direction D of the cover plate 21, and the body The plate end side 18 is connected after the portion 10. In other words, the body portion 10 and the cover plate 21 are connected by the rear plate end side 18. The rear plate end side 18 refers to the end side of the plate 14 after the rear plate 14 intersects the opening face 10h. The cover 21 is constructed such that the rear end side 18 can be rotated relative to the body portion 10 as the axis of rotation. Further, in the present embodiment, the central portion of the rear plate end side 18 which is substantially equally divided into three in the axial direction D is chamfered to form the chamfered portion 18b. The term "chamfering" as used herein refers to forming a surface of a building member, such as an edge of a building member, after forming a ridge line which is a boundary between the panel 14 and the cover 21 after the packaging film cassette 1 is formed. If the edge is removed, the face like the corner is equivalent to the chamfered portion 18b. In the present embodiment, the length of the chamfered portion 18b in the axial direction D is about 120 mm, and the width of the chamfered surface is about 5 mm. By forming the chamfered portion 18b, the packaging film cassette 1 covering the lid portion 20 is gripped by the center portion of the lid 21 and the rear panel 14 by hand, and the corner of the rear panel end side 18 is It becomes gentler and it is easier to hold the packaging film tray 1.

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 covered. The bent side 21f forms a boundary between the cover 21 and the cover sheet 22, and the cover 21 and the cover sheet 22 share a linear side. The height of both ends of the axial direction D of the cover sheet 22 (the length of the short side direction of the rectangular front panel 12) is about 1/2 of the length of the short side direction of the front panel 12, and the height of the central portion of the axial direction D is the front. The length of the short side direction of the board 12 is about 3/4. The structure of the front end side 22t with respect to the bent side 21f is to shorten the distance between the bent side 21f and the front end side 22t in the direction orthogonal to the axial direction D as moving from the center to the respective ends in the axial direction D. With this configuration, the front end side 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 cover portion 20 is covered, and covers the upper portion of the front panel 12 in a pentagonal shape. The cover sheet 22 is constructed such that the length in the axial direction D is slightly longer than the front panel 12 and also longer than the width of the packaging film 91 received in the body portion 10. Thus, the cover sheet 22 is constructed such that the wrap film 91f that can be withdrawn from the body portion 10 is sandwiched between the cover sheet 22 and the front panel 12 over its entire width. A blade 23 for cutting the wrap film 91f is attached to the end side 22t of the cover sheet 22. The blade 23 is disposed in a V shape along the front end side 22t so that the blade edge projects from the front end side 22t.

The side cover piece 25 is disposed orthogonally to both the cover plate 21 and the cover piece 22. The side cover sheets 25 are provided at both ends of the cover plate 21 (covering sheet 22) in total. The basic shape of the side cover sheet 25 is formed such that the length of the long side is the same as the short side of the cover 21, and the length of the short side and the height of the central portion of the cover sheet 22 (the shortest distance from the front end of the V shape to the bent side 21f) ) A slightly rectangular shape. The side cover sheet 25 is fixed to the engaging piece 22j connected to the cover sheet 22 by an adhesive. On the inner side of the side cover piece 25, a concave portion 25d is formed between the engaging piece 22j and the cover plate 21. When the cover portion 20 is covered, the projection 15p provided at the upper end of the rib 15 is fitted in the recess 25d. 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 plate 12.

In the present embodiment, the body portion 10 and the lid portion 20 are formed by processing a coated cardboard having a thickness of about 0.45 to 0.7 mm. Therefore, the packaging film carton 1 has elasticity. Further, in the present embodiment, for convenience of explanation, the main body portion 10 and the cover portion 20 are distinguished from the viewpoint of function, but The body portion 10 and the lid portion 20 are integrally formed by dicing the same sheet of raw paper. The surface of the body portion 10 and the lid portion 20 is subjected to surface treatment such as water repellent processing in addition to the design pattern that can stimulate the consumer's desire to purchase.

The packaging film cassette 1 is formed on the upper portion of the front panel 12, and is cut into the front surface of the front panel 12 to form a flap 12f that is separated from the sub-plate (not shown) and floats to the outside of the main body portion 10. That is, the structure of the front panel 12 includes the ailerons 12f. In the present embodiment, a central portion and a region at both ends in which the front plate 12 is longitudinally (the same direction as the axial direction D) are vacated, and a pair of right and left ailerons 12f are provided along the front plate end side 19. The pair of flaps 12f are formed to be in a position and size covered by the cover sheet 22 when the lid portion 20 is covered. The pair of flaps 12f are configured to be coupled to the sub-plate (not shown) on the front end side 19 so that the front end side 19 can be rotated. On the surface of the pair of ailerons 12f, the stopper portion 50 as a locking means is formed substantially along the front plate end side 19.

In the present embodiment, the stopper portion 50 is formed by applying a UV lacquer. The UV lacquer forming the stopper portion 50 has a property of adhering to the packaging film 91f but not adhering to paper, dust, or the like. Further, the packaging film 91f attached to the stopper portion 50 has a strong adhesion force in a direction parallel to the attachment surface (shear direction), but is in a direction perpendicular to the attachment surface (a direction in which the attachment surface is pulled away). The adhesion is weak. That is, the structure of the stopper portion 50 is such that when the wrap film 91f is pulled out from the body portion 10, that is, in the drawing direction P, along the front plate 12, the stopper portion 50 adheres to the wrap film 91f to avoid the packaging film 91f. Displacement in the withdrawal direction P, when the wrap film 91f is lifted in the direction of separation from the attachment surface, The fresh film 91f will be peeled off. The stopper portion 50 is formed in such a manner that a strip-shaped stopper portion is formed along the front plate end side 19 in the vicinity of the front plate end side 19, and a space is left in the axial direction D in the entire height range of the belt shape. The ground is formed with a plurality of gaps extending in the height direction. The stopper portion 50 of this embodiment is also formed on the surface of the front plate 12 at the center and both ends.

The packaging film cassette 1 is further formed with a central concave embossing 31 as a concave embossing on the cover 21 and a central convex embossing 41 as an outer embossing of the cover. The central concave embossing 31 is formed by embossing the outer surface of the cover 21 by about 0.05 to 0.5 mm. In other words, the central concave embossing 31 is formed as an inner convex portion of the relief portion. The central raised embossing 41 is formed by embossing the outer surface of the cover 21 by about 0.05 to 0.5 mm. In other words, the central raised embossing 41 is formed as an embossed portion of the outer convex. The central concave embossing 31 and the central convex embossing 41 are formed in a predetermined range 1c in the center of the axial direction D. The predetermined range 1c is generally a range in which the user holds the gripping portion when the paper cassette 100 containing the packaging film is used. In the present embodiment, the chamfered portion 18b is formed (in the axial direction D, the cover 21 is approximately One third of the length, that is, about 120mm). The predetermined range 1c corresponds to a range in which a large stress is applied when the wrap film 91f is cut and is to be reinforced. In view of the viewpoint of the reinforcing cover 21, the length of the predetermined range 1c in the axial direction D can also be changed in accordance with the length of the cover plate 21 in the axial direction D, for example, when the length of the cover plate 21 in the axial direction D is 230 mm. The length of the predetermined range 1c in the axial direction D may be 100 mm (about 2/5 of the length of the cover 21), and when the length of the cover 21 in the axial direction D is 160 mm, the predetermined range 1c is in the axial direction D. The length can be 80mm (about 1/2 of the length of the cover plate 21). Further, in the axial direction D, the center of the predetermined range 1c coincides with the center of the cover plate 21. In the present embodiment, five central concave embossments 31 and four central convex embossments 41 are formed in the predetermined range 1c.

Here, referring to Fig. 2, the central concave embossing 31 and the central convex embossing 41 will be described in more detail. 2(A) is a partial plan view of the cover plate 21 around the central concave embossing 31 and the central convex embossing 41, and FIG. 2(B) is a partial cross-sectional view taken along line B-B of (A). First, the undercut embossing 31 will be described. The central concave embossing 31 is preferably formed in two or more predetermined ranges 1c of the cover plate 21. In the present embodiment, as described above, five central concave embossments 31 are formed in the predetermined range 1c of the cover 21. The central concave embossing 31 extends substantially toward the chamfered portion 18b (the rear plate end side 18) with the bent side 21f as a starting point SP. The term "substantially starting from the bent side 21f as the starting point SP" means that the starting point SP of the central concave embossing 31 is connected to the bent side 21f, and the distance from the bent side 21f is several mm. The allowable range of the starting point SP away from the bent side 21f is about 5 mm or less, preferably 2 to 3 mm or less.

The five central concave embossments 31 are arranged symmetrically along the line with a virtual baseline Vb orthogonal to the curved side 21f as an axis of symmetry. The virtual baseline Vb is a virtual straight line passing through a point 21fm among the bent edges 21f and orthogonal to the curved side 21f. The starting points SP of the central concave embossments 31 are generally arranged at equal intervals in the axial direction D. In the present embodiment, the arrangement interval is 10 mm. Among the five central concave embossments 31, a central concave embossing 31 located at the center is placed on the virtual baseline Vb. The central concave embossing 31 which is not placed on the virtual baseline Vb extends from the end of the bent side 21f toward the end of the rear plate end side 18 with respect to the virtual base line Vb. In the present embodiment, the central concave embossing 31 is disposed The closer to the outer side (the side of the rib 15) than the virtual baseline Vb, the greater the extent to which the end is enlarged. According to this configuration, it is possible to generate an effective resistance against the stress generated on the cover plate 21 when the cover sheet 22 is pressed against the front plate 12.

Further, the central concave embossing 31 is continuously formed from the starting point SP substantially at the bent side 21f to at least the virtual straight line SL. The virtual straight line SL is parallel to the bent side 21f, and the virtual straight line SL passes through a point from the starting point SP in the direction orthogonal to the bent side 21f to the 1/6 of the distance Wb of the rear plate end side 18. In the present embodiment, the length of the central concave embossing 31 on the virtual baseline Vb is the longest, about 1/3 of the length of the short side of the cover 21, and is disposed at one of the outermost sides of the cover 21 The embossing 31 is slightly shorter than the central concave embossing 31 (about 1 to 3 mm) in the center, and is disposed on the outermost one of the central concave embossing 31, which is slightly shorter than the adjacent central concave embossing 31. (about 1~3mm). Further, each of the central concave embossments 31 passes through the inside of the virtual semicircular arc Vc. The virtual semicircular arc Vc is a virtual semicircular arc having a predetermined length radius centered on the point 21fm of the bent side 21f. The predetermined length of the radius of the virtual semicircular arc Vc is generally slightly longer (about 2 to 5 mm) than the longest of the distance between the center (middle point 21fm) and the starting point SP of each of the central concave embossments 31. By forming each of the central concave embossments 31 in such a range, when the cover sheet 22 is pressed against the front plate 12, the vicinity of the point 21fm which is easily crushed can be appropriately reinforced.

It is preferable that the center convex embossing 41 is formed in two or more predetermined ranges 1c of the cover plate 21, and in the present embodiment, as described above, four central convex embossings 41 are formed in the predetermined range 1c of the cover plate 21. 4 central raised embossments 41 on the outer side of the virtual semicircular arc Vc from the bent side 21f end to the rear plate The end side 18 ends. The four central raised embossments 41 are on both sides of the virtual baseline Vb, and each of the two is arranged in line symmetry with the virtual baseline Vb as the axis of symmetry. Each of the central projection embossments 41 extends from the end of the bent side 21f toward the end of the rear plate end side 18 with respect to the virtual base line Vb. Among the four central raised embossments 41, one of the farthest distances from the virtual baseline Vb is specifically set to the outermost central raised embossing 41e (corresponding to the "outer cover outer convex embossing"), the outermost central convex The embossing 41e is formed on the outermost side in the axial direction D among all the central concave embossments 31 and the central convex embossments 41 existing in the predetermined range 1c. The central convex embossing 41 (including the outermost central convex embossing 41e) recessed on the side opposite to the central concave embossing 31 passes through the outer surface of the virtual semicircular arc Vc, even at the vicinity of the midpoint 21fm When the bending occurs at the 21st place, the effect of eliminating the bending can be exerted, and when the pressing force on the side of the plate 12 before the cover sheet 22 is released, the effect of restoring the bending of the cover 21 can be exhibited. As described above, by forming the central concave embossing 31 and the central convex embossing 41, when the cover 21 has a tendency to be bent outward to form a convex shape due to the formation of the casing, it is possible to suppress the increase in bending, and Prevent the strength from weakening.

As shown in Fig. 1, end projection embossments 21p are formed at both ends of the cover plate 21 which is closer to the outer side than the predetermined range 1c of the cover plate 21. The end projection embossing 21p is formed in a fold line shape having one corner, and a plurality of ends are arranged in the axial direction D. By forming the end projection embossing 21p at the end of the cover 21, for example, the packaging film cassette 1 is delivered to another person or the like, it is possible to prevent the packaging film cassette 1 from slipping when the end of the packaging film sheet 1 is held. In addition, although omitted in the drawings, the cover sheet 22 may be embossed to make the outer surface of the cover sheet 22 concave, forming a concave embossing, or by embossing. The processing causes the outer surface of the cover sheet 22 to bulge to form a raised embossing. Further, the concave embossing or the embossing embossing formed on the cover sheet 22 may be formed such that one end is substantially connected to the bent side 21f.

With continued reference to Figures 1 and 2, the function of the carton 100 containing the packaging film will be described. The function of the packaging film carton 1 will be explained as one of the functions of the carton 100 containing the packaging film. The unopened carton 100 containing the packaging film is connected to a peeling piece (not shown) via a perforation (not shown) on the front end side 22t at the front end of the cover sheet 22, and the peeling piece (not shown) The front panel 12 is bonded by a plurality of points. When the wrap film 91f is used for the first time, the release sheet (not shown) is peeled off from the front plate 12, and is cut by an eyelet (not shown) to be separated from the cover sheet 22. By opening the packaging film carton 1 as described above, the lid portion 20 is in a state of being rotatable relative to the body portion 10 about the rear plate end side 18.

The unpacked carton 100 containing the packaging film is provided with a film roll 91r in the body portion 10. In the packaging film roll 91r, an extraction sticker (not shown) is attached to the front end of the wrap film 91f, and the extraction tape (not shown) is pinched, and the front end of the wrap film 91f can be peeled off from the wrap film roll 91r. , easily take out the plastic wrap 91f. When the wrap film 91f is used, the wrap film 91f is taken out from the wrap film roll 91r by a necessary length, and then cut by the blade 23. At this time, in a state where the wrap film 91f is taken out by the necessary length, the lid portion 20 is covered, and the wrap film 91f is sandwiched between the front plate 12 and the cover sheet 22, and the center of the cover sheet 22 is pressed with the thumb. The paper cassette 100 containing the packaging film is twisted about the axis 91a so that the center of the blade 23 is stuck into the drawn plastic wrap 91f, even when the wrap film 91f has been attached to the overlapping tableware or the like. It is also easy to cut off, so it is very suitable.

When the figure of the cover sheet 22 is pressed to suppress the sliding of the wrap film 91f, the force by which the cover 21 bends in the direction orthogonal to the axial direction D acts on the cover 21. In particular, since the central predetermined range 1c of the axial direction D is away from the side cover piece 25, it is difficult to enjoy the supporting effect of the side cover piece 25, and there is a tendency that it is easily bent. In the packaging film cassette 1 of the present embodiment, the central concave embossing 31 and the central convex embossing 41 are formed in the predetermined range 1c of the cover 21 as described above, so that the direction orthogonal to the axial direction D can be suppressed. The upper cover 21 is bent, and the crushing of the corners near the bent side 21f (the corner at which the cover 21 and the cover sheet 22 intersect) is suppressed. In particular, since the bending of the cover plate 21 at the initial stage of the bending can be reduced, the damage (deterioration) of the packaging film case 1 can be effectively suppressed.

Since the wrap film 91f sandwiched between the flaps 12f and the cover sheet 22 after the cutting is adhered to the stopper portion 50, it can be prevented from being wound back toward the packaging film roll 91r. Further, when the wrap film 91f is used later, when the lid portion 20 is opened, the aileron 12f floats to the outside of the body portion 10, so that it adheres to the front end of the wrap film 91f formed on the stopper portion 50 of the aileron 12f. It will float from the front plate 12 on the outer side of the aileron 12f, and it is easy to pinch. In particular, since the flap film 1 does not form the ailerons 12f in the central portion, a gap is formed between the center portion of the front panel 12 and the wrap film 91f, so that the cling film 91f can be easily pinched by the fingers deep into the gap.

As described above, according to the packaging film cassette 1 of the present embodiment, the central concave embossing 31 and the central convex embossing 41 are formed in the predetermined range 1c of the cover 21, and therefore, they are housed in the body portion 10. Packaging film roll The plastic wrap 91f is taken out from the cylinder 91r, and the cover portion 20 is covered, and the cover sheet 22 is pressed toward the front plate 12 side. When the wrap film 91f is to be cut, the bending of the cover plate 21 can be suppressed, and the vicinity of the bent side 21f can be suppressed. The corner where it occurs is crushed.

Next, a packaging film carton according to a modification of the embodiment of the present invention will be described with reference to Fig. 3 . Figure 3 (A) is a partial plan view of the central concave embossing 31 of the packaging film carton 1A of the first modification and the cover plate around the central convex embossing 41, and Figure 3 (B) is a second modification. A partial plan view of the central recessed embossing 31 of the packaging film carton 1B and the cover plate around the central raised embossing 41. According to the packaging film carton 1A shown in Fig. 3(A), five central concave embossings 31 and two central convex embossings 41 are formed in the predetermined range 1c. Among the five central concave embossings 31 One, located on the virtual baseline Vb. The remaining four central concave embossments 31 are on either side of the virtual baseline Vb, and each two are arranged in line symmetry with the virtual baseline Vb as the axis of symmetry. Each of the central concave embossments 31 substantially extends toward the chamfered portion 18b (the rear plate end side 18) with the bent side 21f as a starting point SP. The starting point SP of each of the central concave embossments 31 is arranged at an interval of 10 mm. The central concave embossing 31 on the virtual baseline Vb continues from the starting point SP to a position about 1/2 of the distance Wb. The four central concave embossments 31 not located on the virtual baseline Vb continue from the starting point SP to a position about 5/7 of the distance Wb in the direction orthogonal to the curved side 21f. In addition, the four central concave embossments 31 which are not located on the virtual baseline Vb extend in an arc shape (the end is enlarged), and the further toward the rear end side 18 side, the farther away from the virtual baseline Vb, parallel to the curved side 21f. In the direction, the distance between the starting point SP and the end of the rib 15 extending adjacent to the starting point SP is approximately 2 to 2.5 times. Each of the central concave embossments 31 passes through the inside of the virtual semicircular arc Vc.

The two central raised embossments 41 are on either side of the virtual baseline Vb, and are individually arranged in line symmetry with the virtual baseline Vb as the axis of symmetry. Two central raised embossments 41 are formed on the outer side of the virtual semicircular arc Vc. Each of the central raised embossments 41 is curved with the same curvature as the central concave embossing 31 not located on the virtual baseline Vb. The length of the central convex embossing 41 in the short-side direction of the cover plate 21 is about 1/3 of the length of the short side of the cover plate 21. The central projection embossing 41 is formed in a slightly central portion of the short side direction of the cover plate 21. The two central raised embossments 41 are respectively the outermost central raised embossments 41e. Therefore, the center convex embossing 41 is formed on the outermost side in the axial direction D with respect to all the central concave embossments 31 existing in the predetermined range 1c.

In the packaging film carton 1B shown in Fig. 3(B), five central concave embossments 31 and two central convex embossings 41 are formed in the predetermined range 1c, but the embossing is mainly performed in the central concave. The shape of 31 is different from that of the packaging film cassette 1A (see Fig. 3(A)). In the packaging film cassette 1B, five linear concave embossments 31 in a straight line are arranged at equal intervals (for example, 10 mm) and extend in a direction orthogonal to the bent side 21f. Among the five central concave embossments 31, the central concave embossing in the center is located on the virtual baseline Vb. Each of the central concave embossments 31 substantially extends toward the chamfered portion 18b (the rear plate end side 18) with the bent side 21f as a starting point SP. The central concave embossing on the virtual base line Vb of the central concave embossing 31 and one of the two adjacent central embossings continue from the starting point SP to about 1/2 of the distance Wb. The other three central concave embossments 31 continue to the chamfered portion 18b (the outer edge of the cover 21 on the side of the rear plate end side 18). Further, the central concave embossing 31 may not continue to the chamfered portion 18b (the outer edge of the cover 21 on the side of the rear plate end side 18), In the present modification, at least one of them is preferably continued to the chamfered portion 18b (the outer edge of the cover plate 21 on the side of the rear plate end side 18). Each of the central concave embossments 31 passes through the inside of the virtual semicircular arc Vc.

The two central projection embossments 41 of the packaging film cassette 1B are formed to be substantially the same as the central projection embossing 41 of the packaging film cassette 1A (see Fig. 3(A)). In short, the two central convex embossments 41 of the packaging film carton 1B are curved in an arc shape, on the outer side of the virtual semicircular arc Vc, on both sides of the virtual baseline Vb, with the virtual baseline Vb as the axis of symmetry, each line Arranged symmetrically. However, the length of the central projection embossing 41 of the packaging film carton 1B in the short side direction of the cover sheet 21 is longer than the central projection embossing 41 of the packaging film carton 1A (refer to Fig. 3(A)). It is about 1/2 of the length of the short side of the cover plate 21. The central projection embossing 41 is formed in a slightly central portion of the short side direction of the cover plate 21. The two center convex embossments 41 are respectively the outermost center convex embossments 41e formed on the outermost side in the axial direction D with respect to all the central concave embossments 31 existing in the predetermined range 1c.

In the packaging film carton 1A shown in FIG. 3(A) and the packaging film carton 1B shown in FIG. 3(B), a central concave embossing 31 and a central convex are formed in a predetermined range 1c of the cover plate 21. The embossing 41 is pulled out, so that the wrap film 91f is taken out from the wrap film roll 91r housed in the main body portion 10, and the cover portion 20 is covered, and the cover sheet 22 is pressed toward the front plate 12 side to cut the wrap film. At 91f, it is possible to suppress the bending of the cover plate 21 and suppress the corner crushing occurring in the vicinity of the bent side 21f.

In the above description, although the packaging film cassette 1 is formed in a rectangular parallelepiped shape, the bottom plate 13 may be curved along the packaging film roll 91r, or The shape of the front plate 12 and/or the rear plate 14 is curved along the shape of the rectangular shape of the package film roll 91r (in this case, the bottom plate 13 may be omitted). Further, although the chamfered portion 18b is formed on the packaging film case 1, the plate end side 18 may be formed in a straight line across the entire axial direction D without forming the chamfered portion 18b.

In the above description, the central convex embossing 41 is formed in a line symmetry with the virtual base line Vb as the axis of symmetry. However, if it is formed in the predetermined range 1c (more preferably, it is outside the virtual semicircular arc Vc), it may not be a line. symmetry. For example, the following two designs may be employed, that is, the position is line symmetrical but the shape is not line symmetrical (the length is different, one is curved, the other is linear, etc.), or the shape is line symmetrical but the position is not line symmetrical. As long as the foveal embossing 31 is formed within the predetermined range 1c (more preferably, it passes through the inside of the virtual semicircular arc Vc), it may be formed to be line symmetrical with the virtual baseline Vb.

Example

With respect to the rectangular-shaped packaging film paper cassette 1 shown in Fig. 1, it was confirmed that the embossing method formed on the cover 21 was variously changed, and the cover 21 was easily bent. By using the following compression device, the relationship between the amount of compression and the compressive force when the cover sheet 22 in the vicinity of the bent side 21f in the center of the axial direction D is pressed toward the rear end side 18 is calculated, and the bending ease of the cover 21 is calculated. .

Fig. 4 is a perspective view showing an experimental manner of confirming the strength of the cover plate 21. As shown in Fig. 4, the compression device 80 has a circular flat-shaped placing table 81 and a pressing bar 82 formed of a solid round bar. Round flat of the placement table 81 The plate diameter is 200 mm (about 2/3 of the length of the axial direction D of the packaging film cassette 1). When the placement table 81 is placed, the placement surface is made horizontal. The pressing rod 82 is formed to have a diameter of 13 mm and a length of 100 mm. When the pressing bar 82 is disposed, the axis is vertically extended, and the extension line of the axis is passed through the center of the circle of the placing table 81. The compression device 80 is configured to detect the amount of movement (mm) of the pressing bar 82 and the compressive force (N) acting on the pressing bar 82, and can output these values.

With respect to the compression device 80 configured as above, the cover sheet 22 is directed upward, the rear plate 14 is brought into contact with the placement table 81, and the packaging film cassette is placed on the placement table 81. At this time, when the pressing bar 82 is lowered vertically downward, the packaging film cassette is placed at a position where it comes into contact with the covering sheet 22 in the vicinity of the bent side 21f in the center of the axial direction D. The strength of the cover plate 21 is confirmed, and the pressing rod 82 is directed toward the cover sheet 22, and is lowered at a rate of 100 mm/min, and the position where the pressing rod 82 is in contact with the cover sheet 22 is taken as the origin, and the pressing rod 82 is lowered by 10 mm from the origin. The relationship between the amount of movement (mm) of the pressing bar 82 and the compressive force (N) at this time is detected.

The variation of the embossing formed on the cover 21 is as follows.

In the first embodiment, the central concave embossing 31 and the central convex embossing 41 shown in Figs. 1 and 2 are used. Further, in the first embodiment, the end projection embossing 21p shown in Fig. 1 was not formed. In the second, third and comparative examples described below, embossing corresponding to the end projection embossing 21p shown in Fig. 1 was not formed.

In the second embodiment, the central concave embossing 31 and the central convex embossing 41 shown in Fig. 3(A) are used.

Embodiment 3 adopts the concave depression shown in FIG. 3(B) The pattern 31 and the central raised embossing 41.

In the comparative example, a curved convex embossing which is not in contact with both the bent side 21f and the rear plate end side 18 and has an arc shape and an outer surface convex is used (see Fig. 5).

Fig. 5 shows the form of the curved convex embossing 121p of the comparative example. The curved convex embossing 121p is two sides on the two sides of the virtual dividing line SDL, and a total of four are formed. The virtual dividing line SDL is a virtual straight line orthogonal to the axial direction D and passing through the center of the cover plate 21, and is a line that bisects the cover plate 21 in the axial direction D. Each of the two curved convex embossments 121p is formed by line symmetry with the virtual dividing line SDL as an axis. The four curved convex embossments 121p are formed in a predetermined range 1c (refer to FIG. 1). The length of each curved convex embossing 121p in the direction orthogonal to the axial direction D is formed to be 0.4 times the length of the upper cover 21 in the same direction. Further, as viewed between the virtual dividing line SDL and the rib 15, the curved projection embossing 121p advances toward the rear plate 14 end with the cover sheet 22 end, and is bent obliquely to the rib 15. The curve of the curved convex embossing 121p is a ratio of the length orthogonal to the axial direction D, that is, the orthogonal length PV, to the length parallel to the axial direction D, that is, the parallel length PH (PV/PH) is 3.6. The curved convex embossing 121p is formed in a curved shape and is raised toward the virtual dividing line SDL side, and the curve is formed into an arc of a radius of 45 mm. When viewed at the end of the rear plate 14 side, the curved convex embossing 121p is formed such that the curved convex embossing adjacent to the virtual dividing line SDL is about 15 mm from the virtual dividing line SDL (the length of the short side of the cover 21 is approximately 1/3), the curved embossing of the end of the rib 15 is about 15 mm from the adjacent curved embossing. If the line symmetry curve embossing is regarded as the same shape, then 4 curve convex embossing The shape of 121p is the same.

Fig. 6 shows the relationship between the amount of compression and the compressive force of the cover plate 21 in the first to third embodiments and the comparative example. In the graph of Fig. 6, the solid line LE indicates the relationship in the first embodiment, the single-dot chain line LD indicates the relationship in the embodiment 2, the double-dot chain line LF indicates the relationship in the embodiment 3, and the broken line LQ indicates the comparative example. Relationship. When the wrap film 91f is cut, the amount of compression of the cover 21 when the cover sheet 22 is pressed toward the front plate 12 is about 3 to 5 mm (hereinafter referred to as "practical area"), from the graph of Fig. 6. It was confirmed that in the practical region, the compressive force of Examples 1 to 3 was larger than that of the comparative example (mostly 10 to 20% higher), and the strength of the cover 21 was large.
