Figure 7 is a diagram showing the final folding step of the hinged lid package.

As is apparent from FIGS. 1 and 2, the hinge lid package of one embodiment includes a casing 10 and a lid body 12, and the casing 10 and the lid body 12 are each formed in a rectangular parallelepiped shape. The case 10 includes a case body 14 having an upper end that is obliquely opened. Furthermore, the casing 10 further includes a U-shaped inner casing 16. The inner frame 16 projects from the upper end of the casing body 14 and cooperates with the casing body 14 to provide an upper end 18 to the opening of the casing 10.

On the other hand, the lid body 12 is connected to the box body 14 via the hinge 20, and the upper end 18 of the box body 10 can be opened and closed. When the above-described hinge cover package is used as a cigarette package, the inner package is housed in the case 10. The inner package comprises, for example, a bundle of a plurality of filter cigarettes, and an inner wrapper that bundles the bundle.

As is apparent from Fig. 1, the casing main body 14 has four longitudinal edges extending in the longitudinal direction thereof, and at least one of the longitudinal edges forms a circular arc-shaped box side arcuate edge 22. However, in the present embodiment, all of the vertical edges form the box side arcuate edge 22.

On the other hand, when the lid body 12 is in the closed state, the longitudinal edges of the four longitudinal edges of the lid body 12 on the same line as the arc-shaped edge 22 of the box body also form a circular arc-shaped cover side arcuate edge 24. In the present embodiment, all of the longitudinal edges of the casing main body 14 are the casing side arcuate edges 22, and therefore all of the longitudinal edges of the cover body 12 are also the cover side arcuate edges 24.

Viewed in a cross section of the casing 10, the box side arc edge 22 has The arc shape is on the other hand, and the lid side arcuate edge 24 also has an arc shape when viewed in a cross section of the lid body 12.

Therefore, in the hinge lid package of the present embodiment, when the lid body 12 is in the closed state, four combinations of the box side arcuate edge 22 and the lid side arcuate edge 24 on the same line are provided.

At least one of the combinations has a plurality of slits 26 in at least one of the box side arcuate edge 22 and the lid side arcuate edge 24 . The slits 26 are formed in a region of at least a portion of the corresponding arcuate edge and penetrate the region. This type of slit 26 facilitates the formation of a corresponding arcuate edge, that is, the formation of an arc.

In the case of the present embodiment, the box side arcuate edges 22 each have a plurality of slits 26 formed in a region extending from the bottom of the casing body 14 by a predetermined distance. For example, a plurality of slits 26 are arranged in the longitudinal direction of the box-side circular arc edge 22 in the above-described region at intervals, and one slit row 28 is formed.

Each slit 26 traverses the box side arcuate edge 22 obliquely, but can also traverse the box side arcuate edge 22 horizontally.

Furthermore, the slits 26 of the two box side arc edges 22f defining the width of the front wall 30 in the box body 14 are inclined opposite to each other, and on the other hand, the rear wall 32 is defined in the box body 14. The slits 26 of the width side of the box side arc edges 22r are also inclined opposite to each other. At this time, it is preferable that the slits 26 of the box side arcuate edges 22f, 22r on the same side are inclined in opposite directions to each other.

On the other hand, in the case of the present embodiment, among the four cover side arc edges 24, only the width of the front wall 34 defining the cover 12 is 2 The cover side arcuate edges 24f have the same slit row 36 as the slit row 28, and the slit rows 36 are formed on at least a part of the lid side arcuate edge 24f. In the illustrated example, the slit row 36 is formed over the entire length of the lid side arcuate edge 24f. The slit 26 of the slit row 36 is preferably inclined in the same direction as the slit 26 of the box side arcuate edge 22f on the corresponding side.

Further, the two cover side arcuate edges 24r of the lid body 12 defining the width of the rear wall 38 may have a slit row (not shown). At this time, it is preferable that the slit forming the slit row of the lid-side circular arc edge 24r is inclined in the same direction as the slit of the box-side circular arc edge 22r on the corresponding side.

Figure 3 shows the blank 40 used to form the above-described case body 14 and cover 12. The blank 40 is made of, for example, paper, and has a main block 42 and a sub-block 44, and the main block 42 and the sub-block 44 are connected to each other through a folding line 46 which is the aforementioned hinge 20.

In detail, the case body 14 is formed by folding of the main block 42. The main block 42 has a rear plate 48, a bottom plate 50, and a front plate 52 which are sequentially arranged from the side of the folding line 46 toward the longitudinal direction of the blank 40, and the adjacent plates are connected to each other through a folding line indicated by a broken line. The rear plate 48, the bottom plate 50, and the front plate 52 are the rear wall 32, the bottom wall, and the front wall 30 of the above-described case body 14.

On both side edges of the rear plate 48, inner side flaps 56 are respectively connected via the bending belts 54, and the box side arcuate edges 22r are formed by the respective bending belt areas 54. At the lower end of each inner flap 56, an inner bottom flap 58 is joined through a fold line indicated by a broken line. The inner bottom flaps 58 serve as reinforcing members for reinforcing the bottom wall of the casing body 14.

Further, on both side edges of the front plate 52, outer flaps 62 are respectively connected via the bending belt region 60, and the box side arcuate edges 22f are formed by the respective bent belt regions 60. The outer side flaps 62 and the inner side flaps 56 on the same side are superposed on each other through the adhesive to form the side walls of the box body 14. At this time, the bending belt regions 54, 60 form the casing side arcuate rim 22, whereby the side walls of the casing main body 14 have the casing side arcuate edges 22f and 22r, respectively.

On the other hand, the sub-block 44 has a rear plate 64, a top plate 66, a front plate 68, and a front auxiliary plate 70 arranged in this order from the side of the folding line 46 toward the longitudinal direction of the blank 40, and the adjacent plates are passed through each other with a broken line. Connected as shown by the fold line. The rear plate 64, the top plate 66, and the front plate 68 are the rear wall 38, the top wall, and the front wall 34 of the lid body 12, and the front auxiliary panel 70 is a reinforcing member for reinforcing the front wall 34.

On both sides of the rear plate 64, the inner flaps 74 are respectively connected through the bending belts 72, and the above-mentioned lid side arcuate edges 24r are formed by the respective bending belt regions 72. At the upper edge of each inner flap 74, an inner top flap 76 is attached through a folding line indicated by a broken line, and the inner top flap 76 serves as a reinforcing member for reinforcing the top wall of the lid body 12.

Further, on both sides of the front plate 68, the outer flap 80 is connected to each other through the bending belt region 78, and the above-described lid side arcuate edge 24f is formed by each of the bent belt regions 78. The outer side flaps 80 and the inner side flaps 74 on the same side are superposed on each other through the adhesive to form the side walls of the lid body 12. At this time, the bending belt regions 72 and 78 form the lid side circular arc edge 24, whereby the side walls of the lid body 12 have the lid side arcuate edges 24f and 24r.

The aforementioned bending zone 60 can have, for example, a plurality of pressures The trace 82 is used as a fold line. The indentation lines 82 extend over the entire length of the bending zone 60 and are disposed at intervals in the width direction of the bending zone 60.

In detail, the indentation line 82 is formed by press working the blank 40. Fig. 4 is an enlarged view showing the circle IV of the 1-point chain line in Fig. 3. As is apparent from Fig. 4, the indentation line 82 provides a linear recess on the surface of the blank 40, and on the other hand, a ridge line corresponding to the concave portion is provided on the back surface of the blank 40. This collection of indentation lines 82 softens the bend zone 60.

Further, as described above, the slit row 28 is formed in a partial region of the bending zone 60. At this time, as viewed from Fig. 3, the slit row 28 is disposed on the upper portion of the bending zone 60. . However, when the upper portion of the bending zone 60 is folded, it is positioned at the lower portion of the front wall 30 of the casing body 14.

As seen in Fig. 4, the slit 26 forming the slit row 28 extends obliquely across the bend zone 60, i.e., obliquely across the indentation line 82. However, Fig. 4 shows only one slit 26 and three indentation lines 82 for convenience in drawing. Further, in Fig. 4, in order to clearly show the region in which the slit 26 penetrates one of the bending zone 60, the opening width of the slit 26 is exaggerated, but the slit 26 may not have the opening width.

The bend zone 54 also has a combination of a plurality of indentation lines 82 and a slit row 28, similar to the bend zone 60. At this time, as seen from FIG. 3, the slit 28 of the curved region 54 is disposed below the bending band 54.

On the other hand, although the bending zone 72 of the sub-block 44 has only a plurality of indentation lines 82, the bending zone 78 has a slit row 36 and a plurality of indentations. A combination of lines 82. As described above, the slit row 36 is formed over the entire length of the bending zone 78 in the case of the present embodiment.

Figure 5 shows the blank 84 used to form the aforementioned inner frame 16.

The blank 84 is made of, for example, paper, and has a center plate 86 at its center, which has a U-shaped notch 88 at its upper edge, and a projection 90 corresponding to the notch 88 at its lower edge.

At the two side edges of the center plate 86, side flaps 94 are respectively connected through the bending belt regions 92, and the bending belt regions 92 are in the at least part of the same manner as the bending belt regions 54, 60, 78 described above. There is a slitted column 28. In addition, the bend zone 92 can have both the slit row 28 and the aforementioned indentation line 82.

For example, as seen from Fig. 5, the right side bend zone 92 has a slit row 28 at its both ends, whereas the left bend zone 92 has a slit row 28 at its center.

When the U-shaped inner frame body 16 is formed by the above-described blank 84, the inner frame body 16 easily has the same arcuate edge as the above-described case side arcuate edge 22.

The bending zone 54, 60, 72, 78 may have a plurality of the aforementioned scribe lines (Patent Document 1) instead of the plurality of indentation lines 82. At this time, the scribe lines extend parallel to each other along the longitudinal direction of the bending zone, or are inclined with respect to the longitudinal direction of the bending zone, and are arranged at intervals in the longitudinal direction.

Furthermore, the bending zones 54, 60, 78, 92 do not have to have indentations. Line 82 or a line such as a score line. That is, since the bending zones 54, 60, 78, 92 all have the aforementioned slit rows 28 or 36, as long as the slit rows 28, 36 give sufficient weight to the bending zones 54, 60, 78, 92 Softness, that is, no fold line is required.

At this time, the slit row 28 is preferably formed over the entire range of the bending zones 54, 60, 92, and the figure 6 shows a part of the bending zone 54, 60, 92 having only the slit row 28.

However, the bending zone 92 may have any one of the slit row 28 or a plurality of polygonal lines.

The order of folding and bending of the above-mentioned blanks 40, 84 is known to those skilled in the art. Therefore, the detailed description of the order of the steps will be omitted, and the operation of the bending belt regions 54, 60, 78 will be specifically described below.

The bend zones 54, 60, 78 all have a slit row 28 or 36. The slit rows 28 or 36 can further increase the flexibility of the bend bands 54, 60, 78 regardless of the fold line of the indentation line 82 or the like.

Therefore, when the bending belt regions 54, 60, 78 are bent into the box side arc edges 22r, 22f and the lid side arc edge 24f, the box side arc edges 22r, 22f and the cover side arc edges The formation of 24f has become very easy.

Further, the restoring force of the box side arcuate edges 22r and 22f and the lid side arcuate edge 24f to return to the original flat state is also greatly reduced, so that the inner side of the side wall of the case body 14 does not occur. The sheet 56 and the outer flap 62 are then separated, and the outer flap 62 is peeled off from the inner flap 56.

Similarly, the inner flap 74 and the outer flap 80 forming the side wall of the lid 12 do not have the inner flap 74 and the outer side. The flaps 80 are then separated and the outer flaps 80 are peeled off from the inner flaps 74.

As a result, the side walls of the casing body 14 and the lid body 12 are stably formed, and the molding of the hinge lid package is not caused.

In particular, in the above-described embodiment, the slit row 36 of the lid side arcuate edge 24f is disposed over the entire length of the box side arcuate edge 24f, so that it is advantageous in that the side wall of the lid body 12 is stably formed. .

That is, as seen from Figs. 1 and 2, the side wall of the lid body 12 is smaller than the side wall of the box body 14, so that the securing contact area between the outer flap 80 and the inner flap 74 is also small.

However, since the slit row 36 of the bending zone 78 on the side of the outer flap 80 is formed over the entire length of the bending zone 78, the bending zone 78 is excellent in flexibility. The restoring force of the lid side arcuate edge 24f is weak, and even if the area of the side wall of the lid body 12 is small, the outer side of the outer flap 80 and the inner flap 74 can be maintained, and the stable side wall of the lid body 12 can be formed.

On the other hand, the slit rows 28 of the box-side circular arc edges 22f and 22r are disposed only below the box-side arcuate edges 22f and 22r, respectively, and the slit rows 28 are advantageous for the stability of the casing body 14. The formation of the side walls.

In this regard, an additional explanation will be given with reference to FIG.

First, Figure 7 shows the final folding process of the hinged lid package.

In the final folding process, the left and right side walls of the box body 14 and the left and right side walls of the lid body 12 are respectively formed. At this time, the box body 14 and the lid body 12 are as shown by the arrows in FIG. The pair of heater blocks 96 are sandwiched from the left and right.

That is, the outer flap 80 forming the side wall of the cover 12 The inner flap 74 and the outer flap 62 and the inner flap 56 forming the side wall of the box body 14 are respectively sandwiched between the heater block 96 and the inner package IP. Thus, the adhesive between the outer flap 80 and the inner flap 74 and the adhesive between the outer flap 62 and the inner flap 56 are heated from the heater block 96 to be dried to follow the corresponding flaps.

Here, the inner package IP includes a bundle body of the filter cigarette FC and a packaging material W that bundles the bundle body. Further, the filter cigarette FC has a cigarette and a filter which is wound around the filter paper TP and is connected to the base end of the cigarette, and the end of the filter cigarette FC on the filter side is positioned in the inner frame 16.

Therefore, the diameter of the end portion of the filter cigarette FC on the filter side is larger than the diameter of the front end portion of the cigarette to the thickness of the filter paper, and when viewed from the bundle body of the filter cigarette FC, the bundle side of the cigarette side The lower end portion is more easily compressed toward the width of the bundle than the top of the bundle on the filter side.

Moreover, an inner frame 16 is present on the top side of the inner package IP within the hinged lid package.

Therefore, when the case body 14 and the cover body 12 are sandwiched by the pair of heater blocks 96, in particular, the pushing force of the heater block 96 relative to the side wall of the case body 14 cannot be made to extend over the entire length of the side wall. It is uniform, and it is easy to make the pressing force (heating) for the lower portion of the side wall weaker than the pressing force (heating) for the upper portion of the side wall. This is that the adhesion force at the lower portion of the sidewall is weaker than the adhesion at the upper portion of the sidewall.

However, as described above, the slit row 28 of the box side arcuate edges 22f, 22r is formed only in the lower portion of the case side arcuate edges 22f, 22r, and the lower portion of the case side arcuate edges 22f, 22r Restorative force is closer to the side of the box The restoring force at the upper portion of the arc edges 22f, 22r is smaller. Therefore, even if the adhesive force of the adhesive at the lower portion of the side wall becomes weak, the state of the joint between the outer flap 62 and the inner flap 56 can be favorably maintained, and the side wall of the casing body 14 can be stably formed.

Furthermore, the slit rows 28, 36 of the box side arc edges 22r, 22f and the cover side arc edge 24f can be visually recognized from the outside of the hinge cover package, so that the appearance of the hinge cover package is additionally provided by slitting The unique pattern of columns 28 and 36 enhances the aesthetics of the hinged lid package.

Further, since the slit rows 28 of the box-side circular arc edges 22r and 22f are disposed only below the box-side circular arc edges 22r and 22f, the rigidity of the entire casing main body 14 is not extremely lowered.

The present invention is not limited to the above embodiments, and various modifications can be made.

For example, the cover side arcuate edge 24f may have a slit row 36 in a portion thereof rather than in the entire region.

If the rigidity of the entire hinge cover package can be sufficiently ensured, the slit row can be arranged on the entire box side arcuate edge 22 and the lid side arcuate edge 24.

Further, the blanks 40, 84 may be formed of materials other than paper such as plastic.
