Japanese Patent No. 4205587 Japanese Patent No. 4485725 Special table 2008-522910 JP-T-2005-510224 Japanese Patent No. 3253624

  In a conventional box type package with a hinge lid, the lid member is connected to the package body via the hinge so as to be rotatable (turnable), so that it is difficult to obtain a feeling that the lid member opens and closes when the lid member is opened and closed. The lid member cannot be held in an open posture.

  The present invention has been made in view of the above circumstances, and the object thereof is to obtain a good feeling when the lid member opens and closes when the lid member is opened and closed, and the lid member is opened. In some cases, the present invention provides a box-type package that can hold a lid member in an open posture without being gripped by a user.

  The present invention employs the following means in order to solve the above problems. A box-type package according to the present invention includes a package body having an open end at the top, a lid member that is pivotally connected to a rear opening edge of the open end via a hinge, and opens and closes the open end, and the package A flat spring member having one end fixed to the inner surface of the package body and the other end fixed to the inner surface of the lid member. The flat spring member is a bent line parallel to the hinge. With the opening / closing operation of the lid member, the first region portion fixed to the package body and the second region portion fixed to the lid member are relatively bent with the bending line as a boundary. , Between a first tilted state in which the second region part tilts forward with respect to the first region part and a second tilted state in which the second region part tilts backward with respect to the first region part. To reverse the posture.

  According to the box-type package having the above configuration, the flat spring member having a bending line parallel to the hinge that rotatably connects the package body and the lid member is disposed in the package. Since the flat spring member has one end fixed to the inner surface of the package body and the other end fixed to the inner surface of the lid member, the first and second regions are bent by bending the lid member. The part pivots (rotates) relative to the bending line. In this way, when the flat spring member reverses its posture between the first tilted state and the second tilted state, the reaction caused by the reverse is transmitted to the user's hand, and the sound generated at the time of the reverse is generated. Stimulates the user's hearing. Thereby, when a user opens and closes the cover member of a package, the feeling of opening and closing of a cover member can be obtained suitably.

  Since the hinge of the box-type package according to the present invention is provided at the rear opening edge of the opening end, the flat spring member is in the first tilted state when the lid member is in the closed state, and is first in the open state. 2 tilted. The flat spring member is fixed to the package main body side and the lid member, and can be held in a posture in which the lid member is opened in order to restrict free rotation of the lid member.

  Here, it is preferable that the bent line of the flat spring member is formed at a position higher than the hinge. In the flat spring member, the first region is a first dimension that is a straight line connecting the first fixed portion fixed to the package body and the bent line, and the second region in the flat spring member. A sum of a second dimension, which is a dimension of a straight line connecting the first fixing part and the hinge, whose portion is fixed to the lid member, is a dimension of a straight line connecting the first fixing part and the hinge. It is preferably longer than the sum of the dimension and the fourth dimension, which is the dimension of a straight line connecting the second fixing portion and the hinge. According to this, the flat spring member can be more reliably reversed between the first tilted state and the second tilted state in accordance with the opening / closing operation of the lid member.

  The box-type package is provided on the package body, and abutment means that abuts against the first region portion of the flat spring member when the lid member is closed, and restricts the first region portion from moving forward. May be further provided. By providing such a restricting means, the flat spring member is changed from the second tilted state to the first tilted state when the lid member is closed, regardless of the type and amount of objects to be accommodated in the package. It becomes possible to reverse more reliably.

  The objects to be accommodated in the box-type package are not particularly limited, but an aggregate of rod-shaped articles, for example, tobacco products can be preferably exemplified as the objects to be accommodated. That is, the article to be stored according to the present invention may be a tobacco product. Examples of cigarette products include cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), cigarillos, snus, snuff, chewing tobacco, and electronic cigarettes.

  The means for solving the problems in the present invention can be employed in combination as much as possible.

  According to the present invention, in a box-type package, it is possible to obtain a good feeling when the lid member opens and closes when the lid member is opened and closed, and when the lid member is opened, the user does not hold it. It is also possible to hold the lid member in the open posture.

<Example 1>
FIG. 1 is a perspective view of a box-type package (hereinafter simply referred to as “package”) 1 according to a first embodiment. The package 1 is a so-called hinge-lid box-type package having a substantially rectangular parallelepiped shape. The package 1 includes a package main body 2 and a lid member 3 that is rotatably connected to the package main body 2 via a hinge. The lid member 3 may be referred to as “lid”.

  FIG. 1 shows a state in which the package 1 with the lid member 3 opened is viewed from the front side. FIG. 2 is a perspective view of the package 1 with the lid member 3 closed as viewed from the back side. Hereinafter, in this specification, the front side of the package 1 is defined as “front”, and the back side is defined as “rear”. The package body 2 and the lid member 3 in the present embodiment are made of, for example, a paper material, but are not limited thereto.

  The package body 2 includes an outer box 21 and an inner frame 22. The outer box 21 is a box having a shape in which the upper end side of the rectangular parallelepiped shape is cut obliquely. The package body 2 will be described in detail with reference to FIGS. 1 and 2. The package body 2 has a front wall 23, a rear wall 24, a side wall 25, and a bottom wall 26. The front wall 23 and the rear wall 24 each have a rectangular shape, and the rear wall 24 has a rectangular shape whose height is longer than that of the front wall 23, and is disposed opposite to the front wall 23. The pair of side walls 25 connects both side edges of the front wall 23 and the rear wall 24 to each other, and has a trapezoidal shape in which a rectangular upper end is a hypotenuse. That is, the upper edge 25 a of the side wall 25 is inclined so as to connect the upper end of the front wall 23 and the upper end of the rear wall 24. The bottom wall 26 has a rectangular shape and is connected to the lower ends of the front wall 23 and the rear wall 24.

  A hinge 27 is formed at the upper end of the rear wall 24 of the outer box 21. The hinge 27 extends between the rear portions of the upper end edges 25a of the side walls 25, and connects the rear wall 24 and the lid member 3 so as to be rotatable with respect to each other. The outer box 21 configured as described above includes an oblique opening end 21a at the upper end thereof. The lid member 3 is connected to the rear opening edge of the opening end 21a via a hinge 27 so as to be rotatable (turnable).

  The inner frame 22 includes a front frame 28 having a substantially U shape, and side frames 29 connected to both side edges of the front frame 28. The inner frame 22 is bonded to the inner surface of the outer box 21, that is, the inner surfaces of the front wall 23 and the side wall 25 in a state of partially protruding upward from the opening end 21 a at the upper portion of the outer box 21. The inner frame 22 reinforces the opening end 21 a of the outer box 21 and also functions as a guide for guiding the opening and closing of the lid member 3. Here, as is apparent from FIG. 1, the front frame 28 has a substantially rectangular cutout recess 28a. The notch recess 28a opens the front surface of the inner frame 22 widely, and makes it easy to take out tobacco products (contained items).

  The lid member 3 is connected so as to be orthogonal to the rectangular rear wall 31 connected to the hinge 27, a rectangular top plate 32 connected to be orthogonal to the rear wall 31, and the top plate 32. A rectangular front wall 33 and a set of side walls 34. Each set of side walls 34 has a trapezoidal shape, and connects the side edges of the rear wall 31, the top plate 32, and the front wall 33. As described above, the lid member 3 is rotatable about the hinge 27. When the lid member 3 is closed, the oblique side of the side wall 34, that is, the inclined lower end edge of the side wall 34, is the outer box 21 described above. And the upper edge 25a of the side wall 25 coincide with each other.

  The package 1 includes a flat spring member 4 provided on the housing space side of the package body 2. FIG. 3 shows a blank material of the flat spring member 4. The flat spring member 4 is a thin flat plate member. In the present embodiment, the flat spring member 4 is made of a paper material such as card paper or Manila cardboard, like the package body 2 and the lid member 3. The blank material of the flat spring member 4 has a rectangular shape and includes a first region portion 41 and a second region portion 42. A main body side fixing portion 43 and a lid side fixing portion 44 are formed on the outer end sides of the first region portion 41 and the second region portion 42, respectively.

  In the process of manufacturing (assembling) the package 1, an adhesive is applied to the main body side fixing portion 43 in the first region portion 41, and the main body side fixing portion 43 is fixed (fixed) to the package main body 2. Similarly, an adhesive is applied to the lid-side fixing portion 44 in the second region portion 42, and the lid-side fixing portion 44 is fixed (fixed) to the lid member 3. A bend line 45 that is parallel to the short side direction of the blank material of the flat spring member 4 is formed at the boundary between the first region portion 41 and the second region portion 42. This blank material is configured to be able to be bent with respect to both mountain folds and valley folds with a bend line 45 as a boundary.

  The flat spring member 4 will be described with reference to FIGS. 4A and 4B and FIGS. 5A and 5B. FIG. 4A is a perspective view of the package 1 with the lid member 3 closed. FIG. 4B is a perspective view of the package 1 in a state where the lid member 3 is opened. FIG. 5A is a longitudinal sectional view of the package 1 in a state where the lid member 3 is closed. FIG. 5B is a longitudinal sectional view of the package 1 in a state where the lid member 3 is opened. 4A and 4B, the flat spring member 4 is indicated by a solid line, and the other members are indicated by a two-dot chain line. 5A and 5B omit illustration of the inner frame 22.

  In the flat spring member 4, a main body side fixing portion 43 formed on the outer end side of the first region portion 41 is bonded to the inner surface of the outer box 21 in the package main body 2, more specifically, the inner surface of the rear wall 24. . In the flat spring member 4, the lid side fixing portion 44 formed on the outer end side in the second region portion 41 is bonded to the inner surface of the top plate 32 in the lid member 3. As described above, the flat spring member 4 is provided inside the package 1, that is, on the accommodation space side of the package body 2, and is fixed to the inner surface thereof.

  The bent line 45 of the flat spring member 4 is formed to be parallel to the hinge 27 (hinge line). In other words, the flat spring member 4 is bonded to each of the package body 2 and the lid member 3 so that the bending line 45 is parallel to the hinge 27. The flat spring member 4 has a first region portion 41 provided on the package body 2 side and a second region portion 42 provided on the lid member 3 side. Further, the flat spring member 4 has a bending line 45 in the height direction of the package 1 (a direction from the bottom wall 26 toward the top plate 32, corresponding to a direction along the front wall 23 and the rear wall 24). It is fixed to the inner surface of the package 1 so as to be arranged at a high position. Therefore, the flat spring member 4 is installed in a manner in which a part of the first region portion 41 protrudes from the upper portion of the outer box 21 of the package body 2.

  Here, each part dimension of the package 1 is demonstrated. A direction orthogonal to the bending line 45 of the flat spring member 4 is defined as a length direction of the flat spring member 4. In the flat spring member 4, a portion where the main body side fixing portion 43 of the first region portion 41 is fixed to the inner surface (the rear wall 24 in this embodiment) of the outer box 21 in the main body package 2 is referred to as “first fixing. The dimension of the straight line connecting the first fixed part P1 and the bending line 45 is defined as “first dimension S1”. In addition, when the main body side fixing portion 43 has a certain amount of bonding margin as in the present embodiment, the first fixing portion P1 indicates the inner end position of the main body side fixing portion 43 in the first region portion 41.

  On the other hand, in the flat spring member 4, a portion where the lid-side fixing portion 44 of the second region portion 42 is fixed to the inner surface of the lid member 3 (the top plate 32 in this embodiment) is defined as “second fixing portion P <b> 2”. The dimension (distance) of the straight line connecting the second fixed part P2 and the bending line 45 is defined as “second dimension S2”. When the lid-side fixing portion 44 has a certain amount of bonding margin as in the present embodiment, the second fixing portion P2 indicates the inner end position of the lid-side fixing portion 44 in the second region portion 42. The first fixed part P1, the second fixed part P2, the first distance dimension S1, and the second dimension S2 are shown in FIG. 5B.

  Next, the third dimension S3 and the fourth dimension S4 will be described with reference to FIG. 5A. Here, the dimension of the straight line connecting the first fixed part P1 and the hinge 27 is defined as “third dimension S3”. On the other hand, the dimension of the straight line connecting the second fixed part P2 and the hinge 27 is defined as “fourth dimension S4”.

  Here, each dimension of the first dimension S1, the second dimension S2, the third dimension S3, and the fourth dimension S4 is the shortest distance in the direction perpendicular to the hinge 27 and the bending line 45, all between the two points. It is what you point to. The first dimension S1 corresponds to the distance at which the first fixing portion P1 and the bending line 45 are separated in the direction orthogonal to the bending line 45 on the surface of the flat spring member 4. The second dimension S2 corresponds to a distance at which the second fixing portion P2 and the bending line 45 are separated from each other in the direction orthogonal to the bending line 45 on the surface of the flat spring member 4. Further, the third dimension S3 is a direction in which the first fixing portion P1 and the hinge 27 are orthogonal to the hinge 27 (on the package body 2) on the surface of the rear wall 24 of the package body 2 (more specifically, the outer box 21). This corresponds to a distance apart in the height direction. The fourth dimension S4 is the shortest distance that connects the second fixing portion P2 and the hinge 27 linearly. That is, the fourth dimension S4 is not a distance along the surface of the lid member 3.

  The package 1 in this embodiment is configured such that the sum of the first dimension S1 and the second dimension S2 is longer than the sum of the third dimension S3 and the fourth dimension S4 (S1 + S2> S3 + S4). .

  In the package 1 configured as described above, the operation of the flat spring member 4 when the user opens and closes the lid member 3 will be described. The flat spring member 4 is fixed to the inner surface of the package body 2 on the first region 41 side and fixed to the inner surface of the lid member 3 on the second region portion 42 side. Limit movement.

  As shown in FIGS. 4A and 5A, in the state where the lid member 3 is in the closed position, the flat spring member 4 has the first region portion 41 arranged along the rear wall 24 of the package body 2, and this first region portion. The second region 42 is maintained in a first tilted state in which the second region 42 is tilted forward of the package 1 with respect to 41.

  For example, when taking out a tobacco product from the package 1, the user turns the lid member 3 from the closed position to the open position as shown in FIGS. 4B and 5B. With the opening operation of the lid member 3, the lid member 3 turns around the hinge 27 toward the back side of the package 1. In the flat spring member 4, the first region portion 41 is fixed to the inner surface of the rear wall 24 in the package body 2 (outer box 21), and the second region portion 42 is fixed to the inner surface of 32 in the lid member 3. Accordingly, in the flat spring member 4, the first region portion 41 and the second region portion 42 are bent relatively with respect to the bending line 45 as the lid member 3 opens. As a result, the inclination angle of the second region portion 42 with respect to the first region portion 41 gradually becomes gentle (shallow).

  In the process in which the lid member 3 rotates from the closed position to the open position, the flat spring member 4 in the first tilted state is centered on the bend line 45 with moderate bending (bending) due to its own bending rigidity. Bend to. That is, the flat spring member 4 functions as a leaf spring and bends while bending the first region portion 41 and the second region portion 42, and the inclination angle of the second region portion 42 with respect to the first region portion 41 gradually increases. Change your posture in a gentler direction. When the turning angle of the lid member 3 exceeds a certain angle, the flat spring member 4 is reversed with the bend line 45 as a boundary, and the second region portion 42 tilts toward the rear side of the package 1 with respect to the first region portion 41. The posture is changed to the second tilted state.

  When the flat spring member 4 is reversed at the bend line 45, the resistance transmitted to the user is released for a moment by turning the lid member 3 while bending the flat spring member 4, The reaction is transmitted to the user's hand. Thereby, when performing a lid opening operation of the package 1, the user can obtain a feeling that the lid member 3 has been opened to a predetermined opening position, and can evoke a sense of achievement. Further, since the flat spring member 4 generates a sound when it is reversed with the bend line 45 as a boundary, the user can also feel that the lid member 3 is opened by perceiving the sound. In addition, as shown to FIG. 4A and 5B, said open position can illustrate the state which the cover member 3 was open | released to the attitude | position which can take out the cigarette in the package 1 smoothly.

  As shown in FIGS. 4B and 5B, in the state where the lid member 3 is in the open position, the flat spring member 4 is maintained in the second tilted state. In this state, the inner surface of the top plate 32 in the lid member 3 is held by the second region portion 42 of the flat spring member 4, thereby restricting free rotation of the lid member 3. Thereby, the lid member 3 does not wobble due to its own weight or the repulsive force of paper, and the user can maintain the package 1 in the open state shown in FIGS. 4B and 5B without holding the lid member 3. . Here, the limitation on the rotation of the lid member 3 means that the opened lid member 3 limits the rotation operation that the lid member 3 tends to close by its own weight. Needless to say, when the lid member 3 is intentionally closed against this, the lid member 3 is allowed to rotate.

  By the way, since tobacco products such as cigarettes are accommodated in the package 1, the first region portion 41 of the flat spring member 4 is pressed against the rear wall 24 side of the package body by the cigarette. The pressing force with which the cigarette accommodated in the package body 2 presses the first region portion 41 toward the rear wall 24 is transmitted from the first region portion 41 to the second region portion 42 and the lid member 3, and the lid member 3 is opened. Used to hold on. Therefore, in the package 1, when the user opens the lid member 3, the lid member 3 does not wobble, and the lid member 3 can be stably held in the open state.

  When closing the lid member 3 in the opened state, the user performs an operation such as pushing the lid member 3 forward of the package 1 with an appropriate force. As a result, the flat spring member 4 maintained in the second inclined state resists the biasing force that biases the inner surface of the lid member 3, and the lid member 3 rotates (turns) around the hinge 27 in the closing direction. To do.

  At that time, since the first region portion 41 of the flat spring member 4 interferes with the cigarette accommodated in the package body 2 and is pressed by the cigarette, the first region portion 41 can be freely separated from the rear wall 24. Be regulated. As a result, the flat spring member 4 bends about the bend line 45 while bending the first region portion and the second region portion 42. In this way, the flat spring member 4 is gradually inclined with respect to the first region portion so that the second region portion 42 is inclined to the rear side, and finally is reversed with the bend line 45 as a boundary. Then, the posture is changed from the second tilted state to the first tilted state.

  Then, when the flat spring member 4 is reversed at the bend line 45 during the closing operation of the lid member 3, the reaction generated when the flat spring member 4 is reversed or the sound generated when the flat spring member 4 is reversed is the same as during the opening operation. By being transmitted to the user, the user can obtain a feeling that the lid member 3 is securely closed.

  As described above, in the package 1, by providing the flat spring member 4, the free rotation of the lid member 3 around the hinge 27 is limited. Thereby, the attitude | position can be stably maintained in both the state which has the cover member 3 in a closed position, and the state which exists in an open position. In particular, even if the user does not hold the lid member 3, the lid member 3 is held in an open state, so that the user can smoothly remove the object to be stored from the package 1. Therefore, it is possible to provide the package 1 that is very easy to use.

  When the lid member 3 is opened and closed, the flat spring member 4 is configured to reverse the posture between the first tilted state and the second tilted state, so that the lid member 3 is surely opened and closed. A sense can be imparted to the user. Thereby, the operational feeling of the package 1, a feeling of use, etc. can be improved and the commercial value of the package 1 can be raised.

  Further, in the package 1 of this embodiment, the flat spring member 4 is installed so that the bending line 45 is higher than the hinge 27, and the total of the first dimension S1 and the second dimension S2 is the third dimension S3. The flat spring member 4 was configured to be longer than the total with the fourth dimension S4. According to this, when opening the lid member 3, it is easy to push out the vicinity of the bending line 45 of the flat spring member 4 in the first tilted state from the rear side to the front side of the package 1. When the member 3 is closed, it is possible to easily push out the vicinity of the bent line 45 of the flat spring member 4 in the second inclined state from the front side to the rear side of the package 1. Thereby, the flat spring member 4 can be more reliably reversed between the first tilted state and the second tilted state when the lid member 3 is opened and closed.

  As shown in FIG. 5A, an appropriate gap may be formed between the bent line 45 of the flat spring member 4 and the top plate 32 of the lid member 3 when the lid member 3 is closed. . The gap formed between the bending line 45 and the top plate 32 in a state where the lid member 3 is closed is not limited to a specific dimension, but is preferably about 3 mm to 7 mm, for example.

  Moreover, in the package 1 in the present embodiment, the main body side fixing portion 43 in the first region portion 41 of the flat spring member 4 is fixed to the inner surface of the rear wall 24 of the outer box 21. It is also possible to provide flap pieces on both side edges of the end located on the opposite side to the bent line 45 and to bond the flap pieces to each side 25. In the present embodiment, the lid-side fixing portion 44 of the flat spring member 4 is bonded to the top plate 32 of the lid member 3, but it may be bonded to the front wall 33 instead. In the flat spring member 4, the first region 41 is fixed integrally with the inner surface of the package body 2 (outer box 21), and the second region 42 is fixed integrally with the inner surface of the lid member 3. The fixing method is not limited to the bonding and fixing method employed in this embodiment. Therefore, for example, the flat spring member 4 may not be a separate member from the lid member 3 and the package body 2, and the package 1 including the flat spring member 4 may be manufactured by folding a single blank material.

  In the package 1A in the second embodiment, a flat spring member 4A having a function equivalent to that of the flat spring member 4 described in the first embodiment is provided therein. The flat spring member 4A is formed from the same blank material 100 as the lid member 3 and the package body 2, and the connection mode between the lid member 3 and the package body 2 is different from that of the first embodiment.

  The blank material 100 shown in FIG. 6 mainly shows portions corresponding to part of the flat spring member 4 </ b> A and the lid member 3. The blank material 100 is configured using a paper material such as card paper or Manila cardboard, for example. On one end side of the blank material 100, a positioning panel 101 for forming a positioning portion 46 described later is formed. The positioning panel 101 includes a first area panel 102, a second area panel 103, a front wall inner panel 104, a front wall outer panel 105, and a top panel 106 in the order in which they are arranged. A broken line in the figure is a folding line when the blank material 100 is woven.

  Details of the positioning unit 46 will be described later. The first region panel 102 and the second region panel 103 form the first region portion 41 and the second region portion 42 of the flat spring member 4A in a state where the blank material 100 is assembled as the package 1A. A bent line 45 is formed at the boundary between the first region portion 41 and the second region portion 42. In the blank material 100, a slit is formed in a portion corresponding to the bending line 45 in addition to the folding line described above, and the slit can be bent in either the mountain fold direction or the valley fold direction. The technical features of the first region portion 41, the second region portion 42, and the bent line 45 are as described in the first embodiment. Further, the front wall inner panel 104 and the front wall outer panel 105 are folded back to each other, so that the front wall 33 of the lid member 3 is configured as a double wall. The top panel 106 is a panel that forms the top 32 of the lid member 3.

  Of the front wall 33, a portion formed by the front wall outer panel 105 is referred to as an outer wall portion 33A, and a portion formed by the front wall inner panel 104 is referred to as an inner wall portion 33B. In the package 1A, the boundary portion between the second region portion 42 and the inner wall portion 33B of the front wall 33 in the flat spring member 4A corresponds to the second fixing portion P2 described in the first embodiment, and the top plate 32 of the lid member 3 is used. Glued to. Further, in the package 1A, the first region portion 41 and the positioning portion 46 in the flat spring member 4A are bent and disposed as shown. In the package 1 </ b> A, the boundary between the first region portion 41 and the positioning portion 46 in the flat spring member 4 </ b> A corresponds to the first fixing portion P <b> 1 and is bonded to the rear wall 24 of the package body 2.

  As shown in FIG. 6, the length dimension (reference symbol X in the figure) of the positioning panel 101 in the blank member 100 is larger than the length dimension (reference symbol Y in the figure) of the first region panel 102. The above-mentioned “length dimension” refers to a dimension in a direction perpendicular to the bending line 45 formed at the boundary between the first region panel 102 and the second region panel 103 in the blank material 100, for example.

  Here, the positioning portion 46 is a member for preventing the position where the first region portion 41 of the flat spring member 4A is bonded to the rear wall 24 from being shifted from a desired position when the package 1A is manufactured. That is, at the time of manufacturing the package 1 </ b> A, the positioning portion 46 folded back with respect to the first region portion 41 is abutted against the inner surface of the top plate 32 of the lid member 3. In this way, the boundary portion (first fixing portion P1) between the first region portion 41 and the positioning portion 46 is the rear wall of the package body 2 in a state where the front end side of the positioning portion 46 is abutted against the inner surface of the top plate 32. 24 is adhered. If it does in this way, the 1st fixed part P1 to which the 1st field part 41 of flat spring member 4A is fixed to package body 2 can be pasted up easily to a predetermined proper position. That is, by providing the package 1A with the positioning portion 46, when the first region portion 41 of the flat spring member 4A is bonded to the package body 2, it is difficult for the first fixing portion P1, which is the bonding portion, to be displaced. be able to.

  Further, in the flat spring member 4 </ b> A, when the lid member 3 is closed, a gap space is formed above the bending line 45, and the size of the gap formed between the inner surface of the top plate 32 and the bending line 45. Is substantially equal to the difference between the length dimension X of the positioning panel 101 (positioning portion 46) and the length dimension Y of the first region panel 102 (first region portion 41). Therefore, according to the package 1A according to the present embodiment, by adjusting the difference between the length dimension Y and the dimension X, the flat spring member 4A is adjusted so that the height of the bending line 45 becomes a desired height. It can be easily arranged.

<Example 3>
Next, a package 1B according to the third embodiment will be described with reference to FIGS. In the package 1B according to the present embodiment, the inner frame 22A is different from the inner frame 22 according to the first embodiment. Here, the difference from the package 1 of the first embodiment will be mainly described, and members common to the package 1 will be denoted by common reference numerals, and detailed description thereof will be omitted.

  8 and 9 are perspective views of the package 1B according to the third embodiment. The package 1B includes an outer box 21 and an inner frame 22A. The outer box 21 is common to the first embodiment. The inner frame 22 </ b> A includes a front frame 28 having a substantially U shape, a side frame 29 connected to both side edges of the front frame 28, and a back frame 29 </ b> A connected to the front end side of each side frame 29. That is, the package 1B in the present embodiment is characterized in that the inner frame 22A includes a back frame 29A.

  The front frame 28 of the inner frame 22 </ b> A is equal to the internal dimension of the front wall 23 of the outer box 21, and the pair of side frames 29 are equal to the internal dimension of the side wall 25 of the outer box 21. The back frame 29 </ b> A is connected to the end of each side frame 29 that is not connected to the front frame 28. The back frame 29A is folded in a direction orthogonal to the side frame 29 and inside the accommodation space, and is arranged so that the back surface of the back frame 29A faces the surface of the first region portion 41 of the flat spring member 4. Yes.

  As described in the first embodiment, the inner frame 22A configured as described above reinforces the opening end of the outer box 21, functions as a guide for guiding the opening and closing of the lid member 3, and the lid member 3 in the open state. When the flat spring member 4 is closed, the plate spring member 4 in the second tilted state functions as a member that assists the operation when it is reversed to the first tilted state.

  As described above, the object accommodated in the package 1B interferes with the first region portion 41 of the flat spring member 4 during the lid closing operation of the lid member 3, so that the first tilted state is changed from the second tilted state. The reversal of the flat spring member 4 is prompted. However, for example, when the number of cigarettes accommodated in the package body 2 is small, it is difficult to restrict the movement of the first region portion 41 of the flat spring member 4 by the cigarette when the lid member 3 is closed.

  On the other hand, in the package 1B according to the present embodiment, the inner frame 22A including the back frame 29A is installed in the package body 2. The back frame 29 </ b> A contacts the first region 41 of the flat spring member 4 when the lid member 3 rotates from the open position to the closed position, and this first region 41 is the rear wall of the package body 2. It is possible to restrict movement from the 24 side toward the front wall 23 side. In the present embodiment, the back frame 29A corresponds to the restricting means.

  As described above, according to the package 1B of the present embodiment, when the lid member 3 is closed, the back frame 29A restricts the first region 41 of the flat spring member 4 from moving forward. It becomes easier to bend the second region portion 42 relative to the first region portion 41. As a result, reversal of the flat spring member 4 can be promoted, and the transition from the second tilted state to the first tilted state is facilitated. That is, according to the package 1 </ b> B, the flat spring member 4 can be more reliably reversed during the lid closing operation of the lid member 3 regardless of the type and amount of the objects to be accommodated. Therefore, it is possible to provide a box type package that allows the user to obtain a good feeling when opening and closing the lid member 3.

  Although the preferred embodiments of the present invention have been described above, the box-type package according to the present invention can be implemented by combining the embodiments as much as possible. Further, in the present embodiment, the case where tobacco products such as filter cigarettes and double-cut cigarettes are accommodated in the package has been described as a suitable application example of the objects to be accommodated in the box-type package. Articles other than tobacco products may be accommodated.
