Description of the Invention: [Technical Field] The present invention relates to a method for forming a scribe line of a blank (b 1 a n k) and a package manufacturing method and package using the same. [Prior Art] Such a package is generally referred to as a hinged id padkage. The hinged lid type package is formed in a rectangular parallelepiped shape having four corner edges extending along its length. Since such a package has a corner edge, when the manufacturer grasps the package, the hand is attached to the hand. Because of the k-like, it is preferable to have a package member formed as a rounded rounded corner instead of the package having the above-mentioned corner. Here, a blank (plastic sheet) for forming a package having the above-mentioned rounded edge is known (see, for example, Patent Document 1). In Patent Document 1, in order to obtain the above-mentioned rounded edge, a scribe line is formed on _ by embossing a knife to bend the scribe line portion. However, as in the patent document! In the scribe line described, the surface on which the scribe line is formed is expanded, so that the surface on the scribe line side is convex and guided. In this way, it is impossible to directly supply the packaging machine that is used when the content is turned down. In addition, even if the package is replaced by the scribe line (4), it is necessary to return the shape of the circular portion. If the shape of the package is bulged and deformed, it will be a quality problem and cannot be used as a product. (Previous Technical Document) 322976 4 201240795 [Patent Document] Patent Document 1: JP-A-2004-98586 (Summary of the Invention) [Problems to be Solved by the Invention] The present invention can prevent the entire blank material from being formed with a score line Deformation such as warpage recovery, so that it can be stably supplied to the packaging machine, and it is not deformed when it is made into a package. (IV) H-line forming method and manufacturing method of cigarette package having rounded edge using the same And a cigarette package. [Means for Solving the Problems] The present invention provides a method for forming a scribe line of a blank, comprising: forming a thin portion of a case after bending, and forming a resin-made filling material; and as a bending portion The plurality of strips along the edge of the outer edge of the casing are formed, and a plurality of strips along the edge are formed, and the lines of the scribing line form a guard sequence; and in the foregoing line forming process, the The formation of the closing line causes plastic deformation of the surface opposite to the aforementioned _ line forming region to form a groove along the scribe line. Preferably, the case includes a container having a case 2 having an open end, and a box-shaped cover that is connected to the open end through a hinge and opens and closes the open end, and the cover is provided with: a direction extending and used to form a main portion of the stalker and a subsection connected to the end of the main portion through the hinge portion for forming a subsection of the cover, the main portion Having a cross-folding line arranged in the aforementioned direction to be the front wall, the bottom wall and the rear wall of the container 322976 5 201240795 front main panel, bottom panel and rear main panel And an outer side portion and an outer side inner side main flaps of the side wall of the container are respectively connected to the front side of the front main board and the rear main board; the front part has: Arranging in the foregoing direction through the horizontal folding line, and to be the rear sub-wall, the top wall and the front wall of the front cover, the rear sub-panel, the top panel and the front sub-front (front sub- And an inner and outer side sub-flaps of the inner side portion and the outer side portion of the side wall of the cover, respectively, connected to the two sides of the rear sub-board and the front sub-plate; The scribe line forming region is formed between the front main board and the outer main flap, between the rear main board and the inner main flap, between the rear sub-board and the inner sub-fold, and the front pair Between the plate and the aforementioned outer sub-folding plate. Preferably, in the blank forming step, a printing layer is formed on a surface opposite to a surface on which the scribe line forming region is disposed, and the printing layer is used to connect the object stored in the casing. The information is transmitted to the side of the scribe line forming region. Preferably, the blank is made of polyethylene terephthalate. Further, the present invention provides a method for producing a package, which is a method for producing a package having a rounded edge using a method for forming a scribe line of a blank, characterized in that: after the step of forming the scribe line, a method is formed The surface on the side of the scribe line is directed outward, and is bent to form the casing. The present invention also provides a package which is manufactured from a cigarette package manufactured by the method of 322,976,2012, the method of the present invention, and having the aforementioned rounded edges. [Effect of the Invention] According to the present invention, there is provided a process of forming a chain material to be a chain after bending, and a portion to be an outer edge portion of the casing as a bending portion. a scribe line forming step of the plurality of scribe lines at the edge portion; and in the scribe line forming step, the surface opposite to the scribe line forming region is plastically deformed by the formation of the scribe line A groove along the scribe line. That is, the scribing line is formed only on the surface on the side of the outer surface when the billet is formed into a box, and the surface on the one side is scribed, and the surface on the opposite side is plastically deformed to be automatically formed. Groove. Therefore, there is no case where the groove is stretched and stretched to both sides, and the entire blank is not slightly curved. Therefore, the crucible can maintain the shape of the sheet and can be stably supplied to the packaging machine. Since the warpage as described above is prevented, the shape is not deformed when the package is formed. In addition, since it is formed into a shape suitable for a package composed of a main portion and a sub-assembly, which is a scented package (so-called hinged lid type package), it is formed as a scented package and is formed in a scribe line. The area is bent and has a rounded edge 'easy to fit the hand. Further, since the printed layer is formed on the surface opposite to the surface having the line forming region in the blank forming step, the scribe line is not formed directly on the printed layer. Furthermore, if the material is made of polyethylene terephthalate (PET), it is easy to process the score line. In addition, after the _ line is formed, the outer side of the scribed line 7 322976 201240795 is bent to form the aforementioned box. If the part is made in this way, 'because the scribe line forms the 11 field. It is bent along a plurality of lines, so that a cigarette package having a rounded edge can be obtained. Therefore, when grasped by hand, it is easy to fit the hand. [Embodiment] (4) The secret package (box) 1 of the figure 1 is formed as a whole substantially square right μ 4+ and covered with a transparent outer envelope film (not shown). The outer envelope has a seal strip, and when the outer cover film is torn along the seal strip, one of the packs will be injured. The fragrant final package i is provided with a container 2. The upper end L of the container 2 is covered by a cover 6. cover? The 6-series is connected to the trailing edge of the open σ end by means of the hinge 4, and can be rotated around the hinge* to open and close the σ end. More specifically, it can be clearly seen from Fig. 2 that the container 2 has The upper edge of the opening is formed obliquely. Moreover, the container 2 further includes a ^-shaped inner frame (i bribe frame) 1 (). The inner frame 1{) is partially protruded from the upper end of the container 2 to form the open end 12 of the container 2. The front wall of the inner frame ι has an aeees opening σ 14, and the secret opening 14 is formed in a substantially U shape. The cover 6 is formed in a box shape having an obliquely formed lower end of the opening. The lid 6 can cover the open end 12 of the container 2 in a state of covering the protruding portion of the inner frame 10. At this time, the lower end of the cover 6 is in contact with the upper end of the container 2. The container 2 of a conventional package has four corner edges extending in the longitudinal direction thereof, but the container 2 of the present invention has a rounded edge 16 instead of a corner edge. The rounded edges 16 are arcuate in shape from the cross section of the container 2. The lid 6 also has the same rounded edge 18 relative to each of the rounded edges 16. When the cover 6 322976 8 201240795 is covered, it is clear from Fig. 1 that the rounded edge 16 is disposed on the same line as the rounded edge ι8 corresponding to the rounded edge 16 to form a package! a longitudinal edge. Further, as will be described later, the inner frame 1G also has side corner edges ^. In order to obtain a fragrance having such a rounded edge, the present invention provides a manufacturing method as described below. The fragrant final package 1 is formed by bending a sheet-like (four) 3 (see Fig. 3). The Qiu 3 system is formed in a plurality of portions in advance to form a horizontal folding line 5 and is easily bent. The 3rd line can be bent into a box opening/shape by cutting into a desired shape in advance. The material forming step for forming such a chain 3 is carried out in a known order. Here, in the (four) forming step, the folding line (that is, the so-called vertical folding line) which is to be the above-mentioned longitudinal edge is not formed. This month is the part of the fold line that is to be the fold line of the longitudinal edge, that is, it is to be a box! The scribe line forming region 8 of the edge portion 3 performs a scribe line forming step of forming a plurality of scribe lines 7 along the edge portion. The scribe line 7 is formed on the outer surface of the case i to be folded, and the scribe line forming region 8 is tied to the surface to be the outer side, and the scribe line 7 is formed only in the scribe line 7 - the side of the face. In the scribe line forming step, the surface on the opposite side to the scribe line forming region 8 is plastically deformed by the formation of the scribe line 7, and the groove 9 along the scribe line 7 is formed (refer to FIG. 5). ). That is, as described above, the score line 7 is formed only on the side-side surface when the case 1 is made into the case 1 but the score line 7 is formed on the side of the side. The groove 9 is automatically formed by deforming the opposite side. This groove 9 is formed by using the cutting device 11 as shown in Fig. 4. The cutting device U is a 322976 9 201240795 rotary die cutter having ten parallel blades 13 spaced, for example, at a spacing of about 0.8 mm. The scribe line forming region 8 is pressed by the blade 13 to form the scribe line 7 and the groove 9. Specifically, the scribe line forming region 8 is pressed by the blade 13 to form a scribe line 7 on one surface of the blank 3, and if the pressurizing operation is pressurized to a certain depth, it is generated. The blank 3 is plastically deformed to the both sides by the scribe line 7 as a boundary, and finally the concave surface 7 is automatically formed at a position corresponding to the deepest portion 7a of the scribe line 7 on the side opposite to the scribe line forming region 8. Slot 9. This groove 9 extends along the score line 7 as described above. Specifically, the groove 9 is formed along the score line 7 corresponding to each of the score lines 7. The depth D of the scribe line 7 is 134_74/im, for example, when the thickness of the blank is 307.97 μm. Since the groove 9 as described above is formed, the blank 3 does not occur to be stretched to the both sides by the groove 9, and the entire blank 3 is not warped. Therefore, the blank 3 can maintain the shape of the sheet and can be stably supplied to the packaging machine. Further, since the warpage as described above is prevented, the shape of the package 1 is not deformed. In the billet forming step, the surface on the side opposite to the surface on which the score line forming region 8 is disposed is formed to convey information relating to the object stored in the casing 1 to the side of the score line forming region. (that is, the printed layer 15 that conveys information to the outer side when the case 1 is formed). The printed layer 15 should be formed as much as possible in a portion where the cutting process is not desired. However, if the printed layer 15 is formed on the opposite side of the scribe line forming region 8, the scribe line 7 is not formed directly on the surface. The printed layer 15. Further, when the blank 3 is made of polyethylene terephthalate (PET), the handling property is good, and the processing of the score line 10 322976 201240795 7 is also easy. • In order to be applied to the cigarette package 1, the blank 3 has a shape as described below. The blank 3 is provided with a main portion 19 extending in one direction (the direction from the bottom to the top in Fig. 3) for forming the container 2, and an end connected to the main portion 19 through the hinge portion 4 A secondary portion 20 of the cover 6 is formed. The main portion 19 has a front wall 21a, a bottom wall (not shown), and a front wall 21a, a bottom plate 22, and a rear main plate 23, which are arranged in the above-described direction through the horizontal folding line 5. Further, on both sides of the front main plate 21 and the rear main plate 23, outer portions and inner side portions and inner main flaps 25, 26 which respectively form the side walls of the container 2 are connected. The main flaps 25, 26 are connected to the main plates 21, 23 through the above-described score line forming region 8. Further, the inner main flaps 26 are respectively connected to the inner bottom flaps 33 by the transverse folding lines 5, respectively. The inner bottom flap 33 is a reinforcing member of the bottom plate 22 and forms an inner portion of the bottom wall of the container 2. On the other hand, the sub-portion 20 has the perforated line 5 interposed in the one direction, and the sub-plate 27, the top plate 28, and the front sub-plate 29 after the rear wall 27a, the top wall 28a, and the front wall 29a of the cover 6 are to be formed. . On both sides of the rear sub-plate 27 and the front sub-plate 29, inner and outer sub-folding plates 30, 31 which respectively form the inner side portion and the outer side portion of the side wall of the cover 6 are connected. The sub-folding plates 30, 31 are connected to the sub-plates 27, 29 through the above-described scribe line forming region 8. Further, the inner top flaps 30 are connected to the inner top flaps 30 through the horizontal folding line 5, respectively. The inner top flap 32 is a reinforcing member of the top panel 28 that forms the inner portion of the top wall of the lid 6. 11 322976 201240795 As described above, the 'blank forming area 8 is formed between the front main plate 21 and the outer main folding plate 25, between the rear main plate 23 and the inner main folding plate, and the rear sub-plate 27 and the inner sub-folding plate 30. Between the front and the front sub-plate 29 and the outer sub-folding plate 31. That is, the longitudinal edges of the case i are all formed by the score line forming region 8 and the score line 7 is formed in the line forming region 8 as described above, so that the front edge is bent to make the frontal front The edges all become the rounded edges 16, 18. As described above, after the scribe line forming step, the surface on the side on which the scribe line 7 is formed is bent outward to form the box 丨, because the scribe line forming region 8 is scribed along the plurality of lines. The line 7 is bent so that a cigarette package having a rounded edge 16, 18 can be obtained. Therefore, when the package 1 is grasped by hand, it is easy to grip and is easily attached to the hand. Although the present invention shows the hinged lid type package in Figs. 1 and 2, the same applies to the tongue-type package. Further, as shown in Fig. 6, in consideration of the rebound of the bent portion when the blank 3 is bent to form the casing 1, the portion of the scribe line forming region 8 may be formed into an unformed scribe. The line 7 is not formed into the region 34. For example, the non-formation region 34a, specifically, the score line forming region 8 between the rear main plate 23 and the inner main flap 26, and the end portion on the bottom plate 22 side is formed in a triangular shape. Further, for example, the non-formation region 34b is a score line forming region 8 between the rear sub-plate 27 and the inner sub-folding plate 30, and an end portion on the top plate 28 side is formed in a triangular shape. Further, for example, the non-formation region 34c is a score line forming region 8 between the front main plate 21 and the outer main flap 25, and an end portion on the side of the bottom plate 22 is formed in a rectangular shape. 12 322976 201240795 Furthermore, as shown in Fig. 7, the scribe line forming method of the present invention is also applied to the inner frame ι. Specifically, the scribe line forming region 8 is formed between the main plate 17 and the folded plates on both sides thereof, and the aging 7 is formed in the same manner as the above-described blank 3. Thereby, the inner frame 10 having the rounded edge as described above can be obtained.
