The angle β between the front end edge 19 and the boundary line 37 is preferably such that when the wrap film cassette 1 is assembled, the pressing portion 34 can be appropriately pressed against the pressing plate 31 at an angle of the pressing portion 34 with respect to the side plate 15. The width of the pressing portion 34 is considered in the manner of pressing the angle (typically 90°). The degree is determined by 34w (or angle α). The angle β is in a state in which the wrap film cassette 1 is assembled (see FIG. 1), and the angle of the pressing portion 34 with respect to the side plate 15 is maintained in an appropriate state, and the fixing piece 38 is in contact with the back side of the front plate 12. The state becomes the smallest acute angle. The angle β is typically determined between the minimum acute angle and the right angle. In the present embodiment, it is approximately 80° to 85°.

When the plastic wrapper 1 shown in FIG. 1 is assembled from the unfolded view shown in FIG. 2, the pressing plate 31, the front plate 12, the bottom plate 13, and the rear plate 14 are tied at a bending line extending in the axial direction D. The first flap 14j, the second flap 12j, and the third flap 13j are bent at a bending line extending in a direction orthogonal to the axial direction D, respectively. Then, the second fin 12j is overlapped on the outer side of the first fin 14j, and the second fin 12j is overlapped on the outer side of the first fin 14j, and then the third fin 13j is formed, thereby forming the rectangular body portion 10 to which the pressing plate 31 is connected. . The side plate 15 is configured by superposing the first fin 14j, the second fin 12j, and the third fin 13j. Further, the fixing piece 38 is bent toward the inner side of the main body portion 10 so as to be close to the front plate 12, so that the boundary line 37 between the fixing piece 38 and the intermediate portion 35 is folded, and the pressing piece 33 is folded at the auxiliary line 36. Thereby, the pressing portion 34 protrudes toward the opposite side plate 15. At this time, the compressing force is applied to the fixing piece 38 and the intermediate portion 35, so that the fixing piece 38 and the intermediate portion 35 are stabilized, and as a result, the pressing portion 34 is also positioned with respect to the body portion 10. That is, the pressing piece 33 is fixed to the main body portion 10 in cooperation with the fixing piece 38. In the present embodiment, the pressing portion 34 is located on the opening surface 10h. At this time, in the present embodiment, since the angle β (see FIG. 3) is formed to be approximately 80° to 85°, the fixing piece 38 does not come into contact with the back surface of the front plate 12 and floats, but the degree of floating does not hinder The rotation of the wrap roll 91 is performed. The pressing plate 31 is disposed on the inner side of the main body portion 10 (on the side closer to the wrap film roll 91r) than the pressing portion 34. With this arrangement, when the front end edge 19 of the pressing plate 31 is rotated as the rotation axis and is to be opened to the outside of the main body portion 10, both ends of the pressing plate 31 in the axial direction D are blocked by the pressing portion 34, thereby The pressing plate 31 is prevented from opening to the outside. Further, the fixing piece 38 is pressed against the front plate 12 side by the force received from the intermediate portion 35, so that the pressing piece 33 can be stabilized even if it is not attached to the front plate 12, but it can also be contacted by The way the back of the front panel 12 determines the angle After β (see FIG. 3), the surface portion 10 is further firmly fixed to the main body portion 10 by the surface.

On the other hand, in the cover plate 21, as shown in FIG. 2, the side cover sheets 25 are connected to both ends of the axial direction D. A joint piece 22j is connected to both ends of the cover sheet 22 in the axial direction D. The rear plate 14, the cover plate 21, and the cover sheet 22 are bent at a bending line extending in the axial direction, and the side cover sheets 25 and the engaging pieces 22j are respectively bent at a line extending in a direction orthogonal to the axial direction D. The three-dimensional cover portion 20 is formed by being folded over the outer side of the engaging piece 22j and then the side cover piece 25 as described above.

In the case where 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 conveyed to the carton 100 containing the cling film in the following state. Manufacturing site: when viewed in the unfolded view shown in FIG. 2, between the pressing plate 31 and the fixing piece 38 and the front plate 12 (front plate end side 19), between the bottom plate 13 and the rear plate 14, and the cover plate 21 and The cover sheets 22 are bent between the cover sheets 22, and after the cover sheets 22 and the cut pieces 29 are superposed on the front plate 12, the cut pieces 29 are then folded into a flat state at a plurality of points. In the plastic wrapper 1 in a folded state, the first flap 14j, the second flap 12j, the third flap 13j, the side cover sheet 25, and the engaging piece 22j are not bent at a bending line orthogonal to the axial direction D. It is folded, so it becomes the unjoined state. In the plastic wrapper 1 in a folded state, the first flap 14j, the second flap 12j, the third flap 13j, the side cover sheet 25, and the joining piece 22j are peeled off from the wrap film cassette 1 to be flat, but The manufacturing efficiency is improved, and it is usually not assembled, but is manufactured in a folded state. In this case, the folded wrap film paper cassette 1 is considered to be in a state of being assembled, and may be regarded as one of the plastic wrap.

The folded plastic wrap paper cassette 1 is first formed in a rectangular tubular shape with open ends at the manufacturing place of the carton 100 containing the wrap film, and is inserted into the wrap film roll 91r from one end surface, according to the first fin 14j. The second flap 12j, the third flap 13j, the engaging piece 22j, and the side cover piece 25 are sequentially bent, and the second flap 12j is joined to the first flap 14j and the third flap 13j, and the joining piece is joined. 22j and the side cover sheet 25 are next, whereby the paper box 100 containing the wrap film is formed. This embodiment The cling film cassette 1 is not configured to extend the pressing plate 31 in the axial direction D and to lock the main body portion 10 from the outer side of the side plate 15 in order to suppress the rotation of the pressing plate 31, so that the assembly can be used without pressing. The cartoning machine (carton assembly machine) of the plastic wrapper of the board 31 can suppress equipment investment and mass production. Further, when the wrap film cassette 1 is in the folded state, when the pressing plate 31 and the lid 21 are attached, the manufacturing position of the paper cassette 100 containing the wrap film is formed into a rectangular tube having both ends open. It is preferable that the pressing plate 31 does not block the space in which the wrap roll 91r is inserted. For this purpose, the pressing plate 31 and the cover plate 21 are preferably made of the following strength: when the plastic wrapper 1 in the folded state is formed into a rectangular tubular shape with open ends, it is not peeled off, and is provided with a wrap film. When the cut sheet 29 is removed from the state of the paper cassette 100, it is easily peeled off when the lid portion 20 is opened. Further, when the wrap film cassette 1 is in a folded state, the fixing piece 38 and the lid 21 are not attached, whereby the fixing piece 38 is also close to the front plate 12 even when the rectangular tube is formed in both ends. Next, the pressing piece 33 can be supported when the side plate 15 is formed.

The operation of the carton 100 containing the wrap film will be described with continued reference to Figs. 1 to 3 . The function of the wrap film cassette 1 will be described as one of the functions of the carton 100 containing the cling film. The unopened carton 100 containing the wrap film is attached to the cut end piece 29 (see FIG. 2) via the perforated eye line 29c (see FIG. 2) on the front end side 22t, and the cut piece 29 is attached to the front end of the cover sheet 22. A plurality of points are connected to the front panel 12. When the preservative film 91f of the carton 100 containing the wrap film is reached for the first time, the cut piece 29 is peeled off from the front plate 12, and cut at the perforated eye line 29c to be separated from the cover sheet 22. In this manner, the wrap film cassette 1 is unsealed, whereby the lid portion 20 is in a state of being rotatable relative to the main body portion 10 around the rear plate end side 18.

In the paper cassette 100 containing the wrap film after the opening, the pressing plate 31 is initially placed on the pressing piece 33 (outer side). In this state, when the front end edge 19 of the pressing plate 31 is opened to the outside as a rotation axis, the wrap roll 91r is inserted into the main body 10. The wrap film roll 91r is attached with a drawing seal (not shown) at the front end of the wrap film 91f, and the front end of the wrap film 91f is peeled off from the wrap film roll 91r by sucking the extraction seal (not shown). Thus easy The fresh-keeping film 91f is taken out. After the prepreg 91f is withdrawn, the pressing plate 31 is rotated around the front end edge 19 to be closed, and the pressing plate 31 is inserted under the pressing piece 33. At this time, the coated cardboard constituting the wrap film cassette 1 has elasticity, and the portions of the pressing plate 31 which are adjacent to the front end edge 19 in the axial direction D are cut into a quarter arc shape, so that if the pressing is performed When both ends of the axial direction D of the plate 31 are close to each other and the pressing plate 31 is flexibly bent, it is easy to hide the pressing plate 31 under the pressing piece 33. In this way, if the pressing plate 31 is located closer to the inner side of the main body portion 10 than the pressing piece 33, even if the pressing force is applied to the pressing plate 31 to the outside, the pressing plate 33 can be prevented, so that the pressing plate 31 can be prevented from being moved toward the outer side. The outside opens. Further, in the present embodiment, since the concave portion 31d is formed in the pressing plate 31, the pressing plate 31 can be configured to be located inside the main body portion 10 from the beginning, and the concave portion 31d can be formed from the concave portion 31d. The seal film (not shown) is pinched by the adjacent gap 10s, and the wrap film 91f is taken out.

When the cover film 20 is opened, the pinch sheet 12f is floated on the outer side of the main body portion 10, so that the front end of the wrap film 91f is floated from the outer side of the pinch sheet 12f. Hold it. After the front end of the wrap film 91f is pinched, the wrap film 91f of a desired length is taken out from the wrap film roll 91r and cut by the cutter blade 23. At this time, since the wrap film 91f has self-adhesiveness, the wrap film roll 91r is to be swelled from the main body portion 10 as the wrap film 91f is taken out. However, since the wrap film cassette 1 has the pressing plate 31, even if the wrap roll 91r is to be swelled, the pressing plate 31 can be prevented from bulging. Since the pressing plate 31 is pressed by the pressing piece 33 connected to the side plate 15 so as not to open to the outside, it is possible to prevent the pressing plate 31 from being swelled together with the wrap roll 91r. Further, since the pressing piece 33 is fixed to the main body portion 10 in cooperation with the fixing piece 38, the pressing plate 31 can be appropriately pressed. When the fresh-keeping film 91f that has been taken out is cut, the cover portion 20 is closed while the wrap film 91f is taken out by the required length, and the wrap film 91f is held by the front plate 12 and the cover sheet 22, and the cover sheet 22 is pressed with the thumb. In the center, when the center of the cutting blade 23 is cut into the drawn cling film 91f, the plastic wrapper 100 is twisted around the axis 91a, even if the wrap film 91f is attached to the wrapped tableware or the like. It is easy to cut and is preferred.

After the fresh-keeping film 91f to be used is cut, the front end of the wrap film 91f connected to the wrap roll 91r is usually left between the front plate 12 and the cover sheet 22, but enters as in the direction of the opening face 10h. In the state of being placed on the pressing plate 31 in the wrap film cassette 1 including the pressing plate 31, it is possible to avoid the rewinding and adhere to the wrap roll 91r. When the fresh-keeping film 91f 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 wrap film 91f which is connected to the wrap film roll 91r after being cut is left at the pressing plate. 31, thereby avoiding adhesion to the wrap roll 91r. Further, in order to prevent the leading end of the cut-off film 91f after the cutting from being rewound to the wrap roll 91r, it is also possible to apply a varnish or a label or the like before the cover portion 20 is closed to the portion covered by the cover sheet 22. A locking mechanism for attaching the cling film 91f is provided at a part or all of the 12 or the pinch piece 12f or a position of the pressing plate 31 facing the front plate 12 opposite to the cover plate 21.

As described above, according to the carton 100 containing the wrap film of the present embodiment, the wrap film cassette 1 is configured such that both ends of the pressing plate 31 in the axial direction D are pressed by the pressing piece 33, and the pressing piece 33 and the fixing are fixed. Since the sheet 38 is configured to be fixed (fixed) so as not to move relative to the main body portion 10, the wrap film roll 91r can be appropriately prevented from being swelled from the main body portion 10 by the withdrawal of the wrap film 91f with a relatively simple configuration.

In the above description, the cutting blade 23 is formed in a V shape along the front end side 22t, but may be formed in a straight line shape. When the cutting blade is formed in a straight line, the wrap film 91f is usually cut from one end of the width of the preservative film 91f toward the other end.

In the above description, the main body portion 10 is formed in a rectangular parallelepiped shape, but may be formed into a shape other than a rectangular parallelepiped shape. For example, the bottom plate 13 is bent along the wrap roll 91r or the front plate 12 and the rear plate are connected. The cross section of 14 orthogonal to the axial direction D is formed in a triangular shape.

In the above description, the kneading sheet 12f and the finger hole 12h are formed in the front plate 12, but the pinch piece 12f and the finger hole 12h may not be formed.

In the above description, the concave portion 31d is formed on the side of the plate 14 side after the pressing plate 31, However, the side of the plate 14 side after the pressing plate 31 may be formed in a straight line, and in this case, it is preferably formed to be parallel to the rear plate end side 18 (or the front plate end side 19). Alternatively, a configuration may be adopted in which the pressing plate 31 is formed to have the same size as the opening surface 10h (may also be in contact with the rear plate end edge 18), and a gap for taking out the preservative film 91f is formed inside the pressing plate 31. 10s.

In the above description, the pressing piece 33 is connected to the side plate 15 by being integrally formed with the second flap 12j. The fixing piece 38 is integrally connected to the front plate 12 and connected to the main body portion 10, but may be mutually The pressing piece 33 and the fixing piece 38 which are integrally formed are configured as separate bodies (separate) from the main body portion 10, and are connected to the side plate 15 by attaching the pressing piece 33 to the side plate 15 or to the hole formed in the side plate 15 And attaching to the body portion 10 by attaching the fixing piece 38 to the body portion 10. Further, the fixing piece 38 can be configured to be connected to the main body portion 10 other than the front plate 12 as shown below.

Fig. 4 is a partial perspective view of a wrap film cassette according to a modification of the embodiment of the present invention, showing the second fin 12j and the periphery of the pressing piece, and omitting other portions. In the first modification shown in FIG. 4(A), the second fin 12j is further extended from the second end 19j, and is folded at the second end 19j, and then on the opposite side from the second flap 12j. The mountain fold and the valley fold are formed thereby forming the pressing portion 134, the intermediate portion 135, and the fixing piece 138. The second flap 12j, the pressing portion 134, the intermediate portion 135, and the fixing piece 138 are integrally formed. The pressing piece 134 and the intermediate portion 135 constitute a pressing piece 133. The pressing portion 134 extends horizontally in the direction of the inner side of the main body portion 10 by the mountain fold at the second end side 19j. A mountain fold below the second end edge 19j becomes the auxiliary line 136. The fixing piece 138 is connected to the side plate 15 (main body portion 10) by a surface which is followed by a second piece 12j which is a part of the side plate 15 (see FIGS. 1 and 2). The boundary between the fixing piece 138 and the intermediate portion 135 is appropriately moved away from the second end side 19j, thereby preventing the pressing portion 134 from being rotated around the second end side 19j. The angle formed by the pressing portion 134 and the intermediate portion 135 avoids the rotation of the pressing portion 134, and the pressing portion 134 can appropriately press the pressing plate 31 (refer to FIG. 1), preferably 10°. ~30°, more preferably around 15°.

In the second variation shown in FIG. 4(B), the second fin 12j is further extended from the second end 19j. In the extension, the inside of the extended portion is formed with a track shape 233c of a track and field shape (including two straight lines in parallel and a shape of two semi-arcs connecting them). The slit 233c is formed by leaving a straight portion of the track of the track and field event (not cut), and is formed by another straight portion and a semi-arc portion connected to both ends thereof. The slit 233c is formed on the opposite side of the second flap 12j, and the straight portion that is not cut is disposed on the second end 19j. In the present modification, the length of the slit 233c is approximately 2/3 to 3/4 of the length of the second end side 19j, and the outer side of the slit 233c is connected to the second flap 12j. By folding the portion of the outer side of the slit 233c that is connected to the second flap 12j, the inside of the slit 233c extends horizontally in the direction of the inner side of the main body portion 10 as the pressing piece 233, and the outside of the slit 233c serves as the fixing piece 238. The side plate 15 (the main body portion 10) is connected to the second fin 12j which is formed in a part of the side plate 15 in a face-to-face manner.

In the third modification shown in FIG. 4(C), the second flap 12j extends only the width 34w of the pressing portion 34 corresponding to the wrap film holder 1 (see FIG. 1) from the second end side 19j ( 3 refers to the amount, and the extended portion is cut along the second end 19j at both ends of the second end 19j. Further, the end portion of the cut portion has an angle with respect to the second end side 19j, and two bending lines are formed for each end portion. The bending line on the inner side of the two bending lines is folded as the auxiliary line 336, and the bending line on the outer side is folded as the boundary line 337. The portion sandwiched by the auxiliary line 336 extending from both end portions serves as the pressing portion 334, and the portion sandwiched by the auxiliary line 336 and the boundary line 337 becomes the intermediate portion 335, and becomes a fixing piece 338 outside the boundary line 337. The pressing piece 334 and the intermediate portion 335 constitute a pressing piece 333. The fixing piece 338 is connected to the side plate 15 (the body portion 10) by being joined to the second fin 12j constituting one of the side plates 15.
