<Structure of package>

[0019] Figs. 1 and 2 are perspective views of a hinged-lid package (hereinafter, simply called "a package") 1 according to a first embodiment. Figs. 1 and 2 are perspective views of the package 1 seen from a diagonally front side of a frontage. The package 1 is a box-shaped package with a hinge lid that forms a substantially rectangular parallelepiped-shape as a whole. The package 1 includes an outer box 2 as a containing portion, a lid 3 as a lid portion that is connected to the outer box 2 rotatably via a hinge 5, and an inner frame 4 that is fitted to the outer box 2. Hereinafter, in the present description, a frontage side of the package 1 is defined as "a front side", and a back side is defined as "a rear side" except for a case specially mentioned. Further, a lid side of the package 1 is defined as "an upper side", and an opposite side (a bottom side of the package) is defined as "a lower side". As a material that is used for the package 1, a paper material such as cardboard, and manila board is preferably used, but the material of the package 1 is not limited to this. For example, as the material of the package 1, not only a resin material such as a plastic but also other materials can be properly used. In the case of using a paper material for the material of the package 1, a paper material with a basic weight of 100 g/m² or more and 400 g/m² or less, for example, may be used.

[0020] The outer box 2 is a box body having a shape in which an upper end side of a rectangular parallelepiped-shape is diagonally cut out. The outer box 2 has a front wall 21, a rear wall 22, a pair of side walls 23 and a bottom wall 24. The front wall 21 forms a substantially rectangular shape, the rear wall 22 forms a rectangular shape, and the front wall 21 and the rear wall 22 are disposed to face each other. In more detail, the front wall 21 has a hexagonal shape in which upper corner portions of a rectangular shape are diagonally cut off. Further, the rear wall 22 has a height dimension longer than the front wall 21. The side walls 23 connect both side edges of the front wall 21 and the rear wall 22 to one another. The bottom wall 24 is connected to lower ends of the front wall 21, the rear wall 22 and the side walls 23, and has a rectangular shape. An upper end edge 23a of the side wall 23 connects an upper end of the front wall 21 and an upper end of the rear wall 22. The outer box 2 has a diagonal open end 25 at an upper portion.

[0021] The outer box 2 has a front side edge portion 26 having a square (a right angle) shape. The front side edge portions 26 form boundary portions of the front wall 21 and the respective side walls 23, and are edge portions that connect the front wall 21 and the side walls 23. The front side edge portion 26 is a so-called square edge, and corresponds to a front side edge portion at a containing portion side according to the present invention. Further, at upper ends of the respective front side edge portions 26, inclined surface locking edges 27 that are formed by diagonally cutting off upper end portions of the respective front side edge portions 26 are formed. In the present embodiment, the inclined surface locking edge 27 corresponds to a locking portion according to the present invention.

[0022] Further, the hinge 5 is provided at a rear side opening edge of the outer box 2, namely, an upper end of the rear wall 22. The hinge 5 extends along the rear wall 22 of the outer box 2, and rotatably connects the lid 3 to the rear wall 22. Note that for the purpose of improving the beauty, feel or the like, embossing, flock finishing by using staple pile (flock), pseudo embossing by applying varnish (varnishing) thickly or the like may be properly applied to an outer surface of the outer box 2.

[0023] The lid 3 is a box-shaped lid member having a front wall 31, a rear wall 32, a pair of side walls 33 and a top wall 34. In the present embodiment, the lid 3 corresponds to a lid portion according to the present invention. In the lid 3, the front wall 31 and the top wall 34 have substantially rectangular shapes, and the rear wall 32 has a rectangular shape. The rear wall 32 of the lid 3 is connected to the rear wall 22 of the outer box 2 via the hinge 5, and is disposed to face the front wall 31. Further, the top wall 34 is connected to the rear wall 32 to be orthogonal to the rear wall 32. Further, the pair of side walls 33 connect the rear wall 32, the top wall 34 and the front wall 31, and have substantially trapezoidal shapes. The lid 3 which is formed as above is capable of rotating with respect to the outer box 2 with the hinge 5 as a center, and opens and closes the open end 25 by being put on the open end 25 of the outer box 2. Note that when the lid 3 is closed, lower end edges of the side walls 33 of the lid 3 coincide with the upper end edges of the side walls 23 in the outer box 2.

[0024] The lid 3 has front side edge portions 36 each having a chamfered shape. The front side edge portions 36 form boundary portions of the front wall 31 and the respective side walls 33, and are edge portions that connect the front wall 31 and the side walls 33. The front side edge portion 36 is a so-called chamfered edge, and corresponds to a front side edge portion of the lid portion according to the present invention. At lower ends of the respective front side edge portions 36, protruded claws 37 that protrude downward are formed. In the present embodiment, the protruded claw 37 corresponds to a locked portion according to the present invention.

[0025] The inner frame 4 has a front surface frame 41 that forms a substantially U-shape, and a pair of side surface frames 42 that are connected to both side edges of the front surface frame 41. Further, in the inner frame 4, an edge portion 43 that connects the front surface frame 41 and the side surface frame 42 is in a so-called chamfered shape. A width (a chamfered width) of the edge portion (hereinafter, called "the front side edge portion") 43 in the inner frame 4, and a width (a chamfered width) of the front side edge portion 36 in the lid 3 are substantially equal, and the lid 3 and the inner frame 4 do not interfere with each other when the lid 3 is closed. Further, the inner frame 4 is bonded to an inner surface of the outer box 2 in a state in which the inner frame 4 is partially protruded upward from the open end 25 of the upper portion of the outer box 2. In the present embodiment, the front surface frame 41 is bonded to the front wall 21 in a lap region in which the front surface frame 41 and the front wall 21 of the outer box 2 are laid on each other, but a method and a mode of fixing the inner frame 4 to the outer box 2 are not limited to this.

[0026] The inner frame 4 reinforces the open end 25 of the outer box 2, and also functions as a guide member that guides opening and closing of the lid 3. As is obvious from Fig. 2, the front surface frame 41 has a substantially rectangular cutout concave portion 41a. The cutout concave portion 41a widely opens a front surface of the inner frame 4, and facilitates extraction of cigarettes.

<Blank>

[0027] In the present embodiment, the package 1 is formed by folding and bonding respective parts of a first blank B1 for forming the outer box 2 and the lid 3, and a second blank B2 for forming the inner frame 4. Fig. 3 illustrates the first blank B1, and Fig. 4 illustrates the second blank B2. For the first blank B1 and the second blank B2, a paper material such as cardboard and manila board, or a resin such as a plastic sheet can be used, but the material is not limited to them. Further, in explanation of the blanks, explanation is made with the up and down directions in the drawings as a reference.

[0028] As illustrated in Fig. 3, the first blank B1 has an outer box zone R1 to be the outer box 2, and a lid zone R2 to be the lid 3. The outer box zone R1 has a front wall panel P1 to be the front wall 21 of the outer box 2, and side wall panels P2 and P2 to be the side walls 23 of the outer box 2 connect to both side edges of the front wall panel P1.

[0029] Further, a bottom wall panel P3 to be the bottom wall 24 of the outer box 2 connects to an upper edge (an upper edge in Fig. 4) of the front wall panel P1. A rear wall panel P4 that is located at a side opposite from the front wall panel P1 to be the rear wall 22 of the outer box 2 connects to the bottom wall panel P3. Inner side panels P5 and P5 that face the side wall panels P2 connect to both side edges of the rear wall panel P4. Further, inner bottom flaps P6 connect to lower edges of the respective inner side panels P5, and the inner bottom flaps P6 are laid on the bottom wall panel P3 and reinforce the bottom wall 24 of the outer box 2.

[0030] The lid zone R2 has a rear wall panel P7 to be the rear wall 31 of the lid 3, and a lower edge of the rear wall panel P7 is connected to the rear wall panel P4 in the outer box zone R1 via a folding line and a slit S1. Further, a top wall panel P8 to be the top wall 34 of the lid 3 connects to an upper edge of the rear wall panel P7 in the lid zone R2. Further, inner side flaps P9 to be parts of the side walls 33 of the lid 3 respectively connect to both side edges of the rear wall panel P7. Inner top flaps P10 connect to upper edges of the respective inner side flaps P9, and these inner top flaps P10 are laid on the top wall panel P8 to reinforce the top wall 34.

[0031] Further, a front wall panel P11 that is located at a side opposite from the rear wall panel P7 to be the front wall 31 of the lid 3 connects to an upper edge of the top wall panel P8. An inner font flap P12 further connects to an upper edge of the front wall panel P11. The inner front flap P12 is folded inside and is laid on the front wall panel P11, and thereby reinforces the front wall 31 of the lid 3. Further, side wall panels P14 to be the side walls 33 of the lid 3 respectively connect to both side edges of the front wall panel P11 via edge portion panels P13 to be the front side edge portions 36 of the lid 3. The aforementioned inner side flaps P9 are laid on the side wall panels P14 and are bonded, and thereby reinforce the side walls 34. Further, a protruded portion is formed on upper end sides of the edge portion panel P13 and the side wall panel P14 in such a manner as to be astride the edge portion panel P13 and the side wall panel P14, and the protruded claw 37 of the lid 3 is formed by the protruded portion.

[0032] As illustrated in Fig. 4, the second blank B2 has a front surface panel P15 to be the front surface frame 41 of the inner frame 4, and side surface panels P17 to be the side surface frames 42 connect to both side edges of the front panel P15 via edge portion panels P16 to be the front side edge portions 43 of the inner frame 4.

[0033] The first blank B1 and the second blank B2 which are described above are respectively folded along folding lines illustrated by broken lines in Figs. 3 and 4. As a result, the package 1 including the outer box 2, the lid 3 and the inner frame 4 as illustrated in Fig. 1 and Fig. 2 is formed. In more detail, in the outer box zone R1 of the first blank B1, folding is performed along the respective folding lines, the inner bottom flaps P6 are laid on the bottom wall panel P3, and the inner side flaps P5 are laid on and bonded to the side wall panels P2, whereby the outer box 2 is formed. Subsequently, the front surface panel P15 of the second blank B2 is bonded to the front wall panel P1 of the outer box zone R1, whereby the outer box 2 and the inner frame 4 are integrated.

[0034] Meanwhile, in the lid zone R2 of the first blank B1, folding is performed along the respective folding lines, the inner top flap P10 is laid on the top wall panel P8, and the inner side flaps P9 are laid on and bonded to the side wall panels P14, whereby the lid 3 is formed. Note that in the present embodiment, the inner front flap P12 in the lid zone R2 is not bonded to the front wall panel P11, but may be bonded to the front wall panel P11.

[0035] Referring to Figs. 5A to 5C, an opening and closing operation of the package 1 and a lock mechanism included by the package 1 will be described. In Figs. 5A to C, reference numerals and symbols common to those in Figs. 1 an 2 indicate the same members. Fig. 5A illustrates a state in which the lid 3 of the package 1 is opened. In this state, a user accesses the cigarettes which are the objects to be contained which are contained inside the outer box 2, and can freely extract the cigarettes. Fig. 5C illustrates a state in which the lid 3 in the package 1 is completely closed, that is, a state in which the package 1 is closed. Fig. 5B illustrates a state in which the lid 3 is substantially closed.

[0036] The lock mechanism of the package 1 is a mechanism for restraining the closed lid 3 from being accidentally opened against an intention of the user, in order to improve lid closure of the package 1 (the lid 3). In the present embodiment, the lock mechanism of the package 1 is formed by a combination of the inclined surface locking edge 27 which is provided at the outer box 2 side, and the protruded claw 37 which engages with the inclined surface locking edge 27 and is provided at the lid 3 side. Note that as described above, the protruded claw 37 is formed to protrude toward the lower side of the lid 3, from a lower end of the front side edge portion 36 which connects the front wall 31 and the side wall 33 in the lid 3. Further, the inclined surface locking edge 27 is formed by diagonally cutting off the upper end of the front side edge portion 26 by which the front wall 21 and the side wall 22 of the outer box 2 are connected, and is constructed to be able to receive the protruded claw 37 which is provided at the lid 3 side when the lid 3 is closed.

[0037] Further, as illustrated in Figs. 1, 2 and 5A to C, the protruded claws 37 are formed at both the front side edge portions 36 in the lid 3, that is, a pair of respective front side edge portions 36. Further, the inclined surface locking edges 27 are formed at both of the front side edge portions 26 in the outer box 2, that is, a pair of the respective front side edge portions 26. The lock mechanism of the package 1 is constructed by the combinations of the protruded claws 37 and the inclined surface locking edges 27 which are formed to be engaged with one another at a left and a right of the package 1. Accordingly, the package 1 according to the present embodiment includes the two pairs of lock mechanisms in total at a left front side and a right front side of the package 1.

[0038] Next, an operation at a time of opening and closing the package 1 will be explained based on the drawings. First, when the lid 3 of the package 1 is closed, the package 1 sequentially shifts to the state illustrated in Fig. 5C via the states illustrated in Figs. 5A and 5B. Fig. 5B illustrates the state immediately before the lock mechanism of the package 1 operates, that is, immediately before the corresponding protruded claws 37 and inclined surface locking edges 27 are engaged with one another.

[0039] As described above, in the package 1, the front side edge portions 26 which connect the front wall 21 and the respective side walls 23 of the outer box 2 are square edges having square shapes, and the front side edge portions 36 which connect the front wall 31 and the side walls 33 of the lid 3 are chamfered edges having chamfered shapes. As a result, in the state in which the lid 3 is closed, the front side edge portion 36 at the lid 3 side is disposed at an inner side in a cross sectional direction of the package 1 as compared with the front side edge portion 26 of the outer box 2. In other words, a relative relation of the front side edge portion 26 and the front side edge portion 36 is specified so that the front side edge portion 36 of the lid 3 is disposed in the inner side in the cross sectional direction of the package 1, from the front side edge portion 26 of the outer box 2.

[0040] As described above, in the package 1, in the cross sectional direction, the front side edge portion 36 at the lid 3 side is disposed at the inner side from the front side edge portion 26 of the outer box 2, and therefore, when an operation of closing the lid 3 is performed by relatively rotating the outer box 2 and the lid 3 with the hinge 5 which is formed at the back side of the package 1 as the center, a tip end side of the protruded claw 37 which protrudes from the lower end of the lid 3 engages with the inclined surface locking edge 27 which is provided at the outer box 2. More specifically, the protruded claw 37 collides with an outer surface side of the inclined surface locking edge 27. Subsequently, when the lid 3 is further operated to rotate in a closing direction, the protruded claw 37 rides over the inclined surface locking edge 27 from the outer surface side to an inner surface side of the inclined surface locking edge 27. Thereby, as illustrated in Fig. 5C, the protruded claw 37 of the lid 3 is locked by the inclined surface locking edge 27 of the outer box 2, and the lid 3 is brought into the closed state.

[0041] As above, when the lid 3 is closed, the protruded claw 37 of the lid 3 is locked by the inclined surface locking edge 27 of the outer box 2, whereby the rotational operation in the opening direction of the lid 3 is restricted as long as the protruded claw 37 of the lid 3 does not ride over the inclined surface locking edge 27 from the inner surface side to the outer surface side again. Thereby, an accidental opening operation of the lid 3 which is not intended by a user can be prevented, and lid closing performance of the package 1 can be improved. Namely, the package 1 which is excellent in lid closing performance can be provided.

[0042] Note that when a force is applied in the opening direction of the lid 3 to open the package 1 by the intention of the user, from the state illustrated in Fig. 5C, the protruded claw 37 of the lid 3 rides over the inclined surface locking edge 27 from the inner surface side to the outer surface side, whereby lock of the lid 3 by the inclined surface locking edge 27 is released. Thereby, the lid 3 can be freely rotated in the opening direction, and the user can open the lid 3.

[0043] As above, according to the package 1 according to the present embodiment, excellent lid closing performance is included, and the lock mechanism thereof is constructed by the combinations of the protruded claws 37 and the inclined surface locking edges 27 which are provided at the respective front side edge portions in the lid 3 and the outer box 2. According to the above, the locking portions are not provided in sites near centers which have high utility value as display spaces for advertisement and the like which display advertisement/publicity and the other information relating to the product and the manufacturer of the front wall 21 and the side walls 23 in the outer box 2 side, the protruded region of the inner frame 4, and sites near to centers of the front wall 31 and the side walls 33 in the lid 3 side, and therefore, the display space for advertisement and the like of the package 1 can be sufficiently secured.

[0044] Further, by adopting the new and novel lock method which is not found in the prior art, like the lock mechanism which is constructed by the combinations of the protruded claws 37 which are provided at the front side edge portions 36 of the lid 3 and the inclined surface locking edges 27 which are provided at the front side edge portions 26 of the outer box 2, eagerness to buy of consumers can be aroused. As a result, the commercial value of the package 1, or the product containing the objects to be contained can be further enhanced. Further, according to the lock mechanism adopted by the package 1, the cutouts, the cut and raised pieces and the like which are to be the locking portions do not need to be formed in the inner frame as in the prior art, and therefore, reduction in strength and rigidity of the package 1 also can be avoided.

[0045] As above, according to the package 1 according to the present embodiment, the hinged-lid package excellent in lid closing performance without causing inconveniences such as insufficiency of a display space for advertisement and the like, and reduction in strength and rigidity of the package can be provided.

[0046] The preferred embodiment of the present invention is described as above, and proper changes can be added to the above described embodiment within the range without departing from the gist of the present invention. For example, as a modification of the package 1, the structure of the lock mechanism may be changed. That is to say, another mode may be adopted as the lock mechanism if the lock mechanism is constructed by the combinations of the locking portions and the locked portions which are provided at the respective front side edge portions in the lid 3 and the outer box 2, and the lock mechanism is not limited to the combinations of the protruded claws and the inclined surface locking edges which are described above. Further, the locked portions at the lid 3 side do not always need to be provided at the lower ends of the front side edge portions 36, the locking portions at the outer box 2 side do not always need to be provided at the upper ends of the front side edge portions 26, and the disposition positions may be changed as long as the disposition positions do not depart from the gist of the present invention.

[0047] Further, in the present embodiment, the front side edge portion 26 is made the square edge, and the front side edge portion 36 is made the chamfered edge so that the front side edge portion 36 of the lid 3 is disposed at the inner side of the package 1 from the front side edge portion 26 of the outer box 2, in the state in which the lid 3 is closed, but other shapes may be adopted as the shapes of the respective front side edge portions 26 and 36. For example, the front side edge portion 26 at the outer box 2 side may be made a square edge, and the front side edge portion 36 at the lid 3 side may be made a round edge in a circular-arc shape. Further, if only the front side edge portion 36 of the lid 3 is disposed at the inner side of the package 1 from the front side edge portion 26 of the outer box 2, a combination of the shapes of the front side edge portion 26 at the outer box 2 side and the front side edge portion 36 at the lid 3 side is not limited to the above described illustration, and various shapes can be adopted.

Further, a width dimension of the rear wall 92 is slightly larger than a width dimension of the rear wall 62 in the outer box 6. Further, in a region of a substantially lower half in the rear wall 92, an opening portion 95 is formed. The opening portion 95 is formed throughout an entire width of the rear wall 92. Accordingly, an opening width of the opening portion 95 is substantially equal to or slightly larger than the width dimension of the rear wall 62 in the outer box 6. Note that an edge portion that is formed in a boundary position of the rear wall 92 and the side wall 93 in the first tray portion 9 has a chamfered shape, and is a so-called chamfered edge.

[0057] The front wall 91 of the first tray portion 9 has a substantially rectangular shape, and a height dimension thereof is substantially equal to a dimension that is obtained by subtracting a height dimension of the front wall 71 in the lid 7 from a height dimension of the package 100. Namely, a sum of the height dimension of the front wall 91 in the first tray portion 9 and the height dimension of the front wall 71 in the lid 7 is substantially equal to the height dimension of the package 100. Further, a width dimension of the front wall 91 in the first tray portion 9 is substantially equal to a width dimension of the front wall 71 in the lid 7, and is slightly larger than a width dimension of the front wall 61 in the outer box 6. Further, the front wall 91 of the first tray portion 9 is joined to the front wall 61 of the outer box 6 to be relatively rotatable, via a third hinge 53. The third hinge 53 is formed to extend along an upper end edge of the front wall 91 in the first tray portion 9.

[0058] Respective front side edge portions 96 that are formed in boundary positions of the front wall 91 and the respective side walls 93 in the first tray portion 9 have square shapes. The front side edge portion 96 is a so-called square edge, and corresponds to an outer front side edge portion according to the present invention. Further, at upper ends of the respective front side edge portions 96 in the first tray portion 9, inclined surface locking edges 97 that are formed by diagonally cutting off the upper end portions are formed. In the present embodiment, the inclined surface locking edge 97 corresponds to the locking portion according to the present invention

[0059] Further, the second tray portion 10 of the outer tray 8 has a substantially rectangular shape. The second tray portion 10 has a substantially same size as the top wall 74 of the lid 7, and in the state in which the lid 7 is closed, the second tray portion 10 of the outer tray 8 is laid on the top wall 74 of the lid 7. Further, the second tray portion 10 is joined to a fourth hinge 54 that is formed at a front side edge portion of the top wall 74 in the lid 7, namely, an edge portion forming a boundary of the top wall 74 and the front wall 71 to be relatively rotatable. Note that the first to the fourth hinges 51, 52, 53 and 54 are parallel with one another, and are formed along a width direction of the package 100.

[0064] As illustrated in Fig. 12, the fourth blank B4 has a second lid zone R5 to be a remaining part of the lid 7, and an outer tray zone R6 to be the outer tray 8. The second lid zone R5 has a front wall panel P31 to be the front wall 71 of the lid 3, and an inner front flap P32 that reinforces the front wall panel P31 connects to an upper edge of the front wall panel P31. Further, side panels P33 to be the side walls 73 of the lid 7 respectively connect to both side edges of the front wall panel P31. Further, protruded portions that protrude upward are formed in boundary portions of the front wall panel P31 and the side wall panels P33 which connect to the front wall panel P31, and by the protruded portions, the protruded claws 77 of the lid 7 are formed.

[0065] In the outer tray zone R6, a top panel P34 to be the second tray portion 10 of the outer tray 8 connects to the front wall panel P31 in the second lid zone R5. Further, a rear wall panel P35 to be the rear wall 92 in the first tray portion 9 connects to a lower edge of the top panel P34. Further, side wall panels P36 to be the side walls 93 in the first tray portion 9 respectively connect to both side edges of the rear wall panel P35. Further, a bottom wall panel P37 to be the bottom wall 94 in the first tray portion 9 connects to a lower edge in one of the side wall panels P36. Further, a first reinforcement side panel P38 that reinforces the side wall 93 of the first tray portion 9 by being laid on the other side wall panel P36 connects to a lower edge of the bottom wall panel P37.

[0066] Further, a front wall panel P39 to be the front wall 91 in the first tray portion 9 connects to a right edge of the bottom wall panel P37.

Further, a junction panel P42 that is bonded to the front wall panel P21 of the outer box zone R3 in the third blank B3 connects to a right edge of the front wall panel P39.

[0067] The third blank B3 and the fourth blank B4 which are described above are folded at folding lines illustrated by the broken lines in Figs. 11 and 12. As a result, the package 100 including the outer box 6, the lid 7 and the outer tray 8 as illustrated in Figs. 6 to 10 is formed.

[0068] In more detail, the inner bottom flaps P26 are laid on the bottom wall panel P23 and the inner side flaps P25 are laid on the side wall panels P22 to be bonded, whereby the outer box 6 is formed. Note that by double folding lines in the boundary positions of the front wall panel P21 and the side wall panels P22, the chamfered edges which connect the front wall 61 and the side walls 63 of the outer box 6 are formed. Further, by double folding lines in boundary positions of the rear wall panel P24 and the inner side panels P25, the chamfered edges which connect the rear wall 62 and the side walls 63 of the outer box 6 are formed.

[0069] Further, the inner top flaps P30 are laid on the top wall panel P28, and the inner side flaps P29 are laid on the side wall panels P33 to be bonded, whereby the lid 7 is formed. Note that after the inner front flap P32 is folded back to the front wall panel P31, the inner front flap P32 may be bonded to the front wall panel P31, or does not have to be bonded. Further, by double folding lines in boundary positions of the front wall panel P31 and the side wall panels P33, the chamfered edges that connect the front wall 71 and the side walls 73 of the lid 7 are formed.

[0070] Further, in the outer tray zone R6 of the fourth blank B4, the second reinforcement side panel P40 is bonded to the one side wall panel P36, and the first reinforcement side panel P38 and the third reinforcement side panel P41 are bonded to the other side wall panel P36. Subsequently, the junction panel P42 is bonded to the front wall panel P21 of the third blank B3, whereby the outer tray 8 is formed. Note that by double folding lines in boundary positions of the rear wall panel P35 and the side wall panels P36 in the outer tray zone R6, the chamfered edges which connect the rear wall 92 and the side walls 93 in the first tray portion 9 are formed.

[0071] Further, the first hinge 51 of the package 100 is formed by the folding line and the slit S2 which form a boundary of the rear wall panel P24 in the outer box zone R3, and the rear wall panel P27 in the first lid zone R4. Further, the second hinge 52 of the package 100 is formed by a folding line that forms a boundary of the rear wall panel P35 and the top panel P34 in the outer tray zone R6. Further, the third hinge 53 of the package 100 is formed by a folding line that forms a boundary of the junction panel P42 and the front wall panel P39 in the outer tray zone R6. Further, the fourth hinge 54 of the package 100 is formed by a folding line that forms a boundary of the front wall panel P31 in the second lid zone R5 and the top panel P34 in the outer tray zone R6.

[0072] Next, with reference to Figs. 6 to 10, an opening and closing operation of the package 100 and a lock mechanism included by the package 1 will be described. In the package 100, in the first tray portion 9 of the outer tray 8, a depth dimension of the bottom wall 94 is equal to a depth dimension of the bottom wall 64 in the outer box 6, and a height dimension of the rear wall 92 is equal to a sum of a height dimension of the rear wall 62 of the outer box 6 and a height dimension of the rear wall 72 of the lid 7. Further, a depth dimension of the second tray portion 10 is equal to a depth dimension of the top wall 74 in the lid 7. Therefore, as illustrated in Figs. 6 and 7, in the state in which the lid 7 is closed, the first tray portion 9 of the outer tray 8 can be disposed along an outer surface of the outer box 6 without interfering with the outer box 6. Further, the second tray portion 10 of the outer tray 8 can be disposed along the top wall 74 of the lid 7. Thereby, a whole of the package 100 can be restrained from being bulky when the lid 7 of the package 100 is closed.

[0073] For example, the package 100 is assumed to be placed on a horizontal surface such as a table, for convenience. When the cigarette contained in the package 100 is to be extracted, an operator performs an opening operation of the lid 7 by grasping both of the side walls 93 in the first tray portion 9 of the outer tray 8 with one hand, picking the lid 7 with the other hand, and the like. Namely, the lid 7 is rotated with respect to the outer box 6 with the first hinge 51 as a center.

[0074] The first tray portion 9 is rotatably joined to the outer box 6 of the package 100 via the third hinge 53. Further, the second tray portion 10 is rotatably joined to the lid 7 via the fourth hinge 54. Furthermore, the first tray portion 9 and the second tray portion 10 are rotatably connected via the second hinge 52. Accordingly, when the opening operation of the lid 7 is performed, in an interlocking manner with the opening operation, the first tray portion 9 and the second tray portion 10 rotate with the second hinge 52 as the center, the first tray portion 9 rotates with respect to the outer box 6 with the third hinge 53 as the center, and the second tray portion 10 rotates with respect to the lid 7 with the fourth hinge 54 as the center.

[0075] As a result, the second tray portion 10 which is laid on the top wall 74 of the lid 7 separates from the top plate 74, and the rear wall 92 of the first tray portion 9 which is laid on the rear wall 62 of the outer box 6 separates from the rear wall 62 of the outer box 6. At this time, the first tray portion 9 can be relatively rotated with respect to the outer box 6 with the third hinge 53 as the center without interfering with the rear wall 62 of the outer box 6, because in the rear wall 92 of the first tray portion 9, the opening portion 95 having an opening width which is equal to or slightly larger than the width dimension of the rear wall 62 of the outer box 6 is formed. By doing so, the outer box 6 operates to rise from the outer tray 8 while the lid 7 is opened, as illustrated in Figs. 8 to 10.

[0076] Meanwhile, when the lid 7 is operated in a closing direction by the operator from the state illustrated in Figs. 8 to 10, in the interlocking manner with the rotating operation of the lid 7, the first tray portion 9 and the second tray portion 10 rotate with the second hinge 52 as the center, the first tray portion 9 rotates with respect to the outer box 6 with the third hinge 53 as the center, and the second tray portion 10 rotates with respect to the lid 7 with the fourth hinge 54 as the center, respectively. As a result, an inclination angle of the outer box 6 to the outer tray 8 decreases. Namely, the outer box 6 which is raised with respect to the outer tray 8 falls down to be in a posture along the outer tray 8 again, and is brought into the state illustrated in Figs. 6 and 7.

[0077] As above, according to the package 100 in the present embodiment, the outer tray 8 is included, and therefore, the outer box 6 can be automatically raised from the outer tray 8 in the interlocking manner with the opening operation of the lid 7. Thereby, the operator can easily extract the cigarettes contained inside the package 100. Further, the rising operation of the outer box 6 which is in the interlocking manner with the opening action of the lid 7 as described above is a new action which is not found in the prior art. By adopting the new opening and closing method like this, the package 100 can stimulate the eagerness to buy of consumers, and can enhance the commercial value of the product including the package 100.

[0078] Furthermore, the package 100 includes the lock mechanism for realizing favorable lid closure similarly to the package 1 according to the first embodiment. The lock mechanism is constructed by the protruded claws 77 which are provided at the lid 7, and the inclined surface locking edges 97 which are provided at the first tray portion 9 of the outer tray 8 and are engaged with the protruded claws 77. As is also illustrated in Figs. 8, 9 and the like, the protruded claws 77 are formed at both of the respective front side edge portions 76 in the lid 7, that is, a pair of the front side edge portions 76. Further, the inclined surface locking edges 97 are formed at both of the respective front side edge portions 96 in the first tray portion 9, that is, a pair of front side edge portions 96. Namely, the package 100 includes two pairs of lock mechanisms in total at the left front side and the right front side of the package 100.

[0079] In the package 100, the front side edge portion 96 of the first tray portion 9 in which the inclined surface locking edge 97 is formed at the upper end is made a square edge, and the front side edge portion 76 of the lid 7 in which the protruded claw 77 is formed at the lower end is made a chamfered edge. Therefore, in the state in which the lid 7 is closed, the front side edge portion 76 at the lid 7 side is brought into a state disposed at the inner side in the cross sectional direction of the package 100, as compared with the front side edge portion 96 of the first tray portion 9. Namely, in the package 100, the relative relation of the front side edge portion 96 and the front side edge portion 76 is specified so that the front side edge portion 76 of the lid 7 is disposed at an inner side in the cross sectional direction of the package 100 from the front side edge portion 96 of the first tray portion 9, in the state in which the lid 7 is closed.

[0080] According to the package 100, the protruded claw 77 provided at the lid 7 side is received and locked by the inclined surface locking edge 97 which is provided at the outer tray 8 side, when the lid 7 is closed. In more detail, in a process in which the lid 3 in the opened state is closed, the protruded claw 77 of the lid 7 collides with an outer surface side of the inclined surface locking edge 97 of the outer tray 8. When the lid 7 is further rotated in the closing direction from the above state, the protruded claw 77 of the lid 7 rides over the inclined surface locking edge 97 to the inner surface side from the outer surface side of the inclined surface locking edge 97. As a result, the protruded claw 77 of the lid 7 is locked by the inclined surface locking edge 97, and the lid 7 is locked to the closed state. Thereby, the lid 7 is restrained from being accidentally opened. Thereby, lid closing performance of the package 100 can be improved.

[0081] Note that in the respective embodiments described above, the case of containing tobacco products such as filter cigarettes and plain cigarettes in the package is described as the preferred application example of the objects to be contained which are contained in the package 1, but the objects to be contained are not limited to this, and articles such as sweets and chewing gum may be contained, for example.
