The pack 1 for tobacco products according to the present embodiment is a box-shaped pack having a longitudinal axis A as shown in FIGS. 1 to 6 and enclosed inside by an inner surface 4 made of metal foil paper. Cigarette 3 (cigarette product) is stored.

Such a pack 1 for tobacco products has an inner box having a container 7 including a front surface 10, a rear surface 11, two

side surfaces

12 and 12, and a bottom surface 13, and a hinged lid 8 attached to the container 7. The member 5, the back wall 17, two longitudinal walls 18 extending along the longitudinal axis A, and two upper and lower lateral walls 19 </ b> A and 19 </ b> B extending orthogonally to the longitudinal axis A, and the inner box inside And an outer box member 6 in which a recess 20 for accommodating the member 5 is formed.

Of these, the two

lateral walls

19A and 19B of the outer box member 6 are composed of an upper lateral wall 19A and a lower lateral wall 19B. Further, the inner box member 5 is hinged to a corresponding lower lateral wall 19B of the outer box member 6 so as to rotate along a hinge line 21 formed at a connecting portion between the front surface 10 and the bottom surface 13. .

Therefore, the inner box member 5 can be rotated around the hinge 21 between a first position accommodated in the outer box member 6 and a second position partially taken out from the outer box member 6.

As described above, the hinged lid 8 of the inner box member 5 has the upper wall 14, the rear wall 15, and the two

side walls

16 and 16. The rear wall 15 of the hinged lid 8 is continuous with the back surface 11 of the inner box member 5, and the

side walls

16, 16 are continuous with the

side surfaces

12, 12 of the inner box member 5.

The hinge-type lid 8 is coupled to coupling means 26 provided between the upper wall 14 and the upper lateral wall 19A of the outer box member 6, and the inner box member 5 is taken out from the outer box member 6. The hinged lid 8 is automatically opened.

On the other hand, when the inner box member 5 is housed in the outer box member 6, the hinge type lid 8 is closed by the coupling means 26, and the upper wall 14 of the hinge type lid 8 contacts the front surface 10 of the inner box member 5. Thus, the inner box member 5 is closed by the hinged lid 8.

As described above, the inner box member 5 is removably accommodated in the recess 20 of the outer box member 6. The inner box member 5 includes a container 7 including a front surface 10, a rear surface 11, two

side surfaces

12 and 12, and a bottom surface 13, and a hinged lid 8 attached to the container 7. The hinged lid 8 can be opened and closed freely.

Next, the inner box member 5 having the container 7 and the hinged lid 8 and the outer box member 6 will be further described. The hinged lid 8 is the same as the upper wall 14 parallel to the bottom surface 13, the rear wall 15 occupying the same plane as the back surface 11 and connected to the back surface 11 along the hinge line 9, and the side surfaces 12 of the container 7. And two triangular side walls 16 occupying a plane.

The hinged lid 8 is pivotable about the hinge line 9, and when in the closed position shown in FIG. 1, the free edge formed by the side wall 16 and the upper wall 14 of the hinged lid 8 described above is 7 are arranged in contact with the corresponding free edges respectively formed by the side surface 12 and the front surface 10.

In addition to the main rectangular back wall 17 (FIG. 6) as described above, the outer box member 6 has two longitudinal walls 18 and a longitudinal axis A that are firmly joined around the four sides of the back wall 17. It has an upper lateral wall 19A and a lower lateral wall 19B arranged across.

The outer box member 6 has a recess 20 (FIG. 6). The recess 20 has a back surface 11 of the inner box member 5 in contact with the back wall 17 of the outer box member 6 and a bottom surface 13 in contact with the lower lateral wall 19B. Then, the inner box member 5 is accommodated in such an arrangement that the upper wall 14 contacts the upper lateral wall 19 </ b> A and the side surface 12 contacts the longitudinal wall 18 of the outer box member 6.

The depth of the outer box member 6 is substantially equal to the depth of the inner box member 5 having the lateral side surface 12.

The inner box member 5 is hinged to the edge portion forming the hinge line 21 of the lower lateral wall 19B of the corresponding outer box member 6 along the corner edge (connecting portion) connecting the front surface 10 and the bottom surface 13. . The inner box member 5 is in the first position shown in FIG. 1 and the first position shown in FIG. 4 in which the pack 1 is fully opened by pulling out a part of the inner box member 5 from the recess 20. It becomes possible to rotate around the hinge line 21 between the two positions.

A motion limit coupling means 22 is disposed between the longitudinal wall 18 of the outer box member 6 and the side surface 12 of the inner box member 5, and the motion limit coupling means 22 causes the inner box member 5 to move within a predetermined rotation angle. It rotates on the two hinge lines 21. The movement limiting coupling means 22 includes a pair of tabs 23 that are formed by cuts 24 provided on the side surfaces 12 and whose free ends protrude toward the front surface 10 of the inner box member 5. Each tab 23 engages an adaptively shaped edge of the anti-folding portion 25 formed by the inner surface of the corresponding longitudinal wall 18 so that the inner box member 5 moves around the hinge line 21 as shown in FIG. Angular motion within a limited range is determined when rotating.

The coupling means 26 is disposed between the upper wall 14 of the hinged lid 8 and the corresponding lateral wall 19 of the outer box member 6, and the inner box member 5 is rotated by the coupling means 26 to rotate the outer box member 6. The hinged lid 8 is automatically opened when it is separated from the recess 20 of the above. The coupling means 26 includes a single tab 27 formed by a notch 28 on the outer box member 6 side and protruding from the edge of the upper lateral wall 19 toward the rear wall 17 of the outer box member 6, and a hinged lid 8 and a slot 29 formed in the upper wall 14. Further, a distal end portion 36 is formed at the distal end of the notch 28 of the outer member 6.

The slot 29 serves to form a tab 29a that coincides with the corner edge between the upper wall 14 and the rear wall 15 of the lid.

As shown in FIG. 5, when the inner box member 5 is rotated and taken out from the outer box member 6, the tab 29 a of the inner member 5 is engaged with the notch 28 of the outer member 6. In this case, when the inner box member 5 is pulled out from the outer box member 6, the tab 29a gradually slides into the notch 28 while sliding the tip 36 on the outer member 6 side, so that the tab 29a and the notch 28 are finally The hinged lid 8 is pulled rearward by the engagement, and the hinged lid 8 rotates around the hinge line 9.

As shown in FIGS. 2 and 6, the back wall 17 of the outer box member 6 allows the user to easily remove the inner box member 5 from the outer box member 6 so that the lid 8 automatically opens accordingly. In addition, a circular opening 32 that enables the inner box member 5 to contact the back surface 11 is provided.

In a further embodiment (not shown) of the pack 1, the hinged lid 8 may have a structure having a front wall that occupies the same plane as the front surface 10 of the inner box member 5. In this example, the two side walls 16 exhibit a trapezoidal outline rather than a triangle.

Next, the hinge type lid 8 will be described in further detail. As shown in FIG. 7, which will be described later, the upper wall 14 of the hinge-type lid 8 is provided with an extension 40 which is bent at the tip edge thereof via a folding line 41 to increase rigidity (FIG. 4 (a). ) (B)).

The extension 40 of the upper wall 14 of the hinged lid 8 is bent outward through a folding line 41 to increase the rigidity of the leading edge of the upper wall 14.

That is, the upper wall 14 of the hinge-type lid 8 is made of a punched blank, but when the foldable extension 40 is not provided at the distal end edge of the upper wall 14, the distal end edge of the upper wall 14 has rigidity. Therefore, when the leading edge of the upper wall 14 of the hinged lid 8 comes into contact with the front surface 10 of the inner box member 5, the leading edge of the upper wall 14 is curved and the space between the upper wall 14 and the front surface 10. It is conceivable that a gap occurs in In this case, the powder of tobacco products spills outward from the gap between the upper wall 14 and the front surface 10.

On the other hand, according to the present embodiment, the extension 40 of the upper wall 14 of the hinged lid 8 is bent outward through the folding line 41, so that the rigidity of the leading edge of the upper wall 14 is increased. Can be increased.
When the hinged lid 8 is closed and the upper wall 14 of the hinged lid 8 closes the front surface 10 of the inner box member 5, the folding line 41 or the extension of the upper wall 14 contacts the upper edge of the front surface 10. Will be in touch. In this case, since the leading edge of the upper wall 14 is reinforced by the extension 40 and has high rigidity, the leading edge of the upper wall 14 is not curved. For this reason, the folding line 41 of the upper wall 14 abuts the upper edge of the front surface 10 over its entire length, whereby the front surface 10 of the inner box member 5 can be reliably sealed by the upper wall 14 of the hinged lid 8. .

In the above embodiment, the example in which the extension 40 of the upper wall 14 is bent outward through the folding line 41 is shown, but the present invention is not limited thereto, and the extension 40 of the upper wall 14 is inward. You may bend it up.

Alternatively, the extension portion 40 of the upper wall 14 may be bent inward or outward via a folding line 41 and the extension portion 40 may be bonded to the outer surface or the inner surface of the upper wall 14. Since the extension 40 is bent and bonded to the upper wall 14 in this way, the rigidity of the leading edge of the upper wall 14 can be increased.

That is, when the extension 40 is not bonded to the upper wall 14 of the hinge-type lid 8, the extension 40 can reduce the gap by covering the gap generated between the upper wall 14 and the front surface 10.

Further, when the extension 40 is bonded to the outside of the upper wall 14 of the hinged lid 8, the rigidity of the upper wall 14 can be increased and the generation of a gap with the front surface 10 can be suppressed.

Further, when the extension 40 is bonded to the inner side of the upper wall 14 of the hinge-type lid 8, the rigidity of the upper wall 14 is increased, the generation of a gap with the front surface 10 is suppressed, and the extension 40 is inward. When folded, the upper wall 14 swells downward by the thickness of the paper, so that the gap with the front surface 10 can be reduced.

Next, blanks for the inner box member 5 and the outer box member 6 will be described. As shown in FIGS. 7 and 8, reference numerals 5 ′ and 6 ′ denote two flat blanks of packaging material, and a series of bending steps are performed to form the inner box member 5 and the outer box member 6.
