With reference to FIGS. 1-6, the pack 10 including the box portion 11 and the hinged lid 12 of the first embodiment is shown. The pack includes a front wall 13 and a rear wall 14, left and right side walls 15 and 16 connecting them, and an upper wall 17 and a bottom wall 18. The front wall 13 and the rear wall 14 are the larger walls of the pack and are on the same plane. The left and right side walls 15 and 16 are smaller walls than the front wall 13 and the rear wall 14, and are on the same surface.

The front wall 13 includes a box front wall 13a and a lid front wall 13b. Similarly, the rear wall 14 and the left and right side walls 15 and 16 include the box rear wall 14a, the left and right side walls 15a and 16a of the box and the lid rear wall 14b, and the left and right side walls 15b and 16b of the lid, respectively.

The lid 12 is hinged to the box 11 at a hinge wire 19 on the pack rear wall 14 where the lid rear wall 14b is in contact with the box rear wall 14a. The hinge wire 19 is horizontal and parallel to the top wall 17 and bottom wall 18 of the pack. The box is located at the top of the box and includes an opening 20 for ejecting the contents of the pack. The opening and closing of the opening can be selected by turning the lid 12.

The inner frame 21 is housed inside the box 11. The inner frame 21 includes a front panel 22 and left and right side panels 23 and 24. These panels come into contact with the inner surfaces of the front wall 13a of the box and the left and right side walls 15a and 16a of the box, respectively. The inner frame 21 is attached at a predetermined position and protrudes from the opening 20 of the box 11. The inner frame 21 includes protrusion lock tabs 25 and 26 at left and right end portions 27 and 28 where the front panel 22 contacts the left and right side panels 23 and 24, respectively. As shown by d ₁ <d ₂ in FIG. 5, the left protruding lock tab 25 is shorter than the right protruding lock tab 26.

The upper edge 29 of the box 11 is asymmetrically formed. The upper edge 29 includes a lowered recess 30 located approximately in the middle of the front wall 13a, an inclined edge 31 angled upward from the left side of the recess 30 toward the left wall 15a, and the recess 30. It includes a horizontal edge 32 extending horizontally from the right side toward the right side wall 16a. The box upper edge 33 on the left side of the puck extends approximately linearly from the inclined edge 31 to the end of the hinge wire 19, and the box upper edge 34 on the right side of the puck extends from the horizontal edge 32 to the hinge wire 19. Extends approximately linearly to the end of. Therefore, since the end of the inclined edge 31 on the left side of the pack is higher than the end of the horizontal edge 32 on the right side of the pack, the rear wall 14 and the upper edge 33 of the left box are as shown in FIGS. 2 and 3. The angle θ ₁ between the _two is larger than the angle θ ₂ between the rear wall 14 and the upper edge 34 of the right box.

The present invention is not limited to a particular angle, but in certain embodiments, the angle θ ₁ is 70-80 ° and the angle θ ₂ is 50-65 °. Along with this, the difference between the angle θ ₁ and the angle θ ₂ may be 5 to 30 °. In another embodiment, the angle θ ₁ is 75-80 °, the angle θ ₂ is 55-65 °, and the difference between the angle θ ₁ and the angle θ ₂ may be 10-25 °. In another embodiment, the angle θ ₁ is 75-80 °, the angle θ ₂ is about 60 °, and the difference between the angle θ ₁ and the angle θ ₂ may be 15-20 °. In yet another embodiment, the angle θ ₁ may be about 77 °, the angle θ ₂ may be about 60 °, and the difference between the angle θ ₁ and the angle θ ₂ may be about 17 °.

The lower edge portion of the lid side wall has a shape corresponding to the upper edge portions 33 and 34 of the box side wall, and abuts when the lid is closed. Thus, the shut lines or seams 35, 36 are formed on both sides of the pack with the lower edges of the lid in contact with the upper edges 33, 34 of the box, with the edges 33, 34 relative to the rear wall 14, respectively. The same angles θ ₁ and θ ₂ are formed. Since the angles θ ₁ and θ ₂ formed by the shut line or seams 35 and 36 and the rear wall 14 are different, the seam 35 on the left side of the pack is the pack's seam 35 as shown in FIGS. 2 and 3 as l ₁ <l ₂ . It is shorter than the seam 36 on the right side. In particular, l ₁ is shorter than the seams of conventional smoking packs with hinged lids, such as the packs disclosed in Patent Document 1 below.

FIG. 8 shows a blank 39 for forming the pack 10 of the first embodiment. The blank 39 can be folded along the bending line (shown by the dashed line). The box front wall 13a and the box rear wall 14a, the lid front wall 13b and the lid rear wall 14b, and the pack upper wall 17 and the pack bottom wall 18 have the same reference numbers. The hinge wire 19 is formed at a bending line between the box rear wall 14a and the lid rear wall 14b. The lower edge portion 37 of the lid is formed at a bending line between the front wall 13b of the lid and the inner tab 40 folded inside the lid 12. The blank includes the left side panels 41, 42 of the box. When forming the pack, the left side wall 15a of the box is formed by laminating and pasting these panels. Similarly, the box right side wall 16a is formed by laminating and pasting the box right side panels 43 and 44. The left and right side walls 15b and 16b of the lid are formed by laminating the lid left side panels 45 and 46 and the lid right side panels 47 and 48, respectively. The location of the adhesive for sticking the panels together is indicated by a cross-hatch area "G", and a large number of notched / embossed parallel lines "L" form the rounded edges of the pack. ..

FIG. 7 is a schematic flowchart of an example of a production line for producing a pack 10 of smoking products, in which a cigarette (S1) is placed in a cigarette stand (S2) and foil is supplied from a foil supply unit (S3). Then, the cigarette bundle is wrapped (S4). An inner frame blank is supplied from a blank reel (S5) and placed so as to cover a bundle of cigarettes wrapped in foil (S6). The pack blank 39 is supplied from the blank stack (S7) to the blank base (S8), and the inner frame and the pack blank 39 are bonded at the essential points G in the bonding operation (S9), and the pack blank 39 is bent and pressed in the pressing step (S10). Is placed on a cigarette stack and folded around it to complete the finished product pack 10. After being formed, the pack 10 is packaged and sealed with cellophane to keep the contents fresh until the consumer opens it (S11).

Through the manufacturing process described above, the pack 10 is conveyed in the manufacturing apparatus, especially in the folding and pressing step S10, and thereafter with the pack side walls facing the traveling direction. Through the folding step S10, the leading side of the pack is pressed and held on the holding surface, while the fingers of the device fold the remaining blank panel around the cigarette bundle to form the assembled pack. Therefore, the pack panels that overlap on the leading side are continuously pressed in place to ensure that the panels are glued together and aligned accurately. However, the overlapping panels on the trailing side are only bent in place by the movement of the fingers of the device, which is quickly retracted. Due to this fast folding, misalignment of overlapping panels can occur at the trailing lid / box edge. This is especially noticeable at the seams due to the angle of inclination. The seam forms a shut line between the lid and the box. The steeper the angle of inclination of the seam, the larger and more pronounced the misalignment. The angle θ ₁ between the back wall 14 of the puck and the seam 35 on the trailing side wall 15 is larger, and the seam 35 (l ₁ ) on the trailing side wall is associated with it than the seam 36 (l ₂ ) on the leading side wall. ) Is shorter, the edges of the lid / box face more at right angles to each other, and the seam 35 is more horizontal (ie, more parallel to the top and bottom walls 18 of the pack). By doing this, the misalignment of any side panel can be reduced. Therefore, when transporting the pack 10 through the apparatus, the direction of the pack is determined so that the left side wall 15 is on the trailing side and the right side wall 16 is on the leading side.

In addition, the trailing side of the pack as it passes through the device is easily scratched, which tends to cause peeling of the overlapping panels of the blanks forming the side wall of the pack. As the angle θ between the back wall of the pack and the seam becomes smaller, the upper part of the box side wall adjacent to the hinge wire forms a sharper tip, making it difficult to glue the side panel to that tip, and the side panel. Is easy to peel off. By increasing the angle θ ₁ between the puck rear wall 14 and the seam 35 on the trailing (left) side wall 15, the tip of the upper part of the box side wall 15a adjacent to the hinge wire 19 becomes less sharp. , It becomes easy to glue to the tip portion, and the risk of peeling of the overlapping panels 41 and 42 is reduced. The same applies to the panels 45 and 46 of the lid side wall 15b that follow. This is very beneficial. This is because, as described above, the panels 41/42 and 45/46 that overlap on the trailing side wall of the pack 10 are not pressed as long as the preceding side wall panels and are not fixed in place and are made of adhesive. This is because the time required to form a secure bond is short. By reducing the sharpness of the tip, the risk of peeling of the outermost panels 42 and 45 is reduced. Packs with a small seam angle, resulting in a lower box top edge and a longer lid anterior wall, have several advantages other than those mentioned above. For example, it is easy to take out the contents, and a lot of space for a lock tab for surely closing the lid is secured on the inner frame that protrudes from the box. Therefore, it is beneficial for both arrangements that the pack of this embodiment has different seam angles on each side wall.

Further, a part of the pack manufacturing process includes a step of arranging the tax payment stamp 38 so as to cover the seam of the pack edge (see FIG. 6). The stamp 38 may be a label that has adhesiveness by itself or a label that is attached to a pack. The stamp must be torn the first time the pack is opened, which requires enough force to affect the lid 12. The provision of a short seam 35 (l ₁ ) on _one side wall of the pack reduces the length to be torn and reduces the force required to open the pack. This allows consumers to open the package more easily. In FIG. 6, the stamp 38 extends so as to cover only the left side wall 15 of the pack 10. However, the tax stamp 38 may also be placed over the short seam 35 of the left side wall 15 of the pack, or may extend across the adjacent trailing edge of the pack 10 around the rear wall 14 and the hinge line 19. ..

By asymmetrically designing the locking tabs 25 and 26 on the inner frame 21, the force required for opening can be further reduced. Since the lock tab 25 is shorter than the lock tab 26, the frictional force applied to the inside of the lid 12 is reduced. Therefore, when the pack 10 is opened and the lid 12 is opened, the frictional resistance of the left side of the pack is lower than that of the right side. This allows the tax stamp to supplement the increased force required for opening on the left side rather than the right side of the pack, and also to assist in a small initial tilt when opening the lid to tear and open the tax stamp. .. Also, the pack can be easily opened with one hand.

Pack with one hand by touching a part of the front panel 22 of the inner frame 21 away from the upper edge 29 of the box front wall 13a in the region of the recess 30 where the lower edge 37 of the lid front wall 13b is lowered. Will be easier to open. It becomes easier to put a finger on the lower edge portion 37 of the lid, and it becomes easier to open the pack 10.

Since the lid front wall 13b has different seam angles θ ₁ and θ ₂ on the side walls 15 and 16, the lower edge portion of the front wall 13b of the lid 12 at the opposite corner where the lid front wall 13b is adjacent to the two lid side walls 15b and 16b. The height is different. The lower edge of the front surface of the lid may extend linearly between these different heights. However, as an embodiment, a part of the lower edge portion 37 of the lid front wall 13b is horizontal and parallel to the pack upper surface 17, the bottom wall 18, and the hinge wire 19. By doing so, when the lower edge of the lid front wall faces downward over the entire width of the pack 10 front wall, it is possible to avoid forming a very sharp tip between the seam and the pack rear wall 14 on the side wall of the pack. As described above, the sharp tip causes a problem of separation / peeling of overlapping panels. This embodiment can avoid this problem. Further, the direction in which the lid is pushed open by the horizontal portion of the lower edge portion 37 of the lid front wall 13b is perpendicular to the hinge wire 19. From this, when the lower edge of the lid front wall faces downward over the entire width of the pack 10 front wall, the performance is improved and naturally when the lid is pushed open as compared with the case where the lid is obliquely related to the hinge line. You can open the lid.

The horizontal portion of the lower edge 37 of the lid front wall 13b is the center of the lid front wall 13b from the viewpoint that the user can open the pack naturally and intuitively at a natural position for pushing open the pack lid 12. It is preferable to be in.

Although all four vertical edges of the pack are rounded in the pack 10 of the embodiments shown in the figure and described herein, the present invention is not intended to be limited to this design. Another embodiment includes different designs for the ridge. For example, an oblique or right angle or a right angle on the front surface and a right angle on the back surface.
