In addition, the detailed description about the adhesion | attachment of the blank of the inner body 9 of the packaging container 1 and the inner body 9 and the outer body 8 is abbreviate | omitted here.

  When the packaging container 1 formed in this way forms the packaging container 1 from the blank 2, the cigarette T is packaged in the cigarette T that is packaged in the inclusion body, thereby packaging the cigarette T. In the packaging container 1 in which the cigarette bundle is packaged, the outer periphery of the packaging container 1 is encased in an enveloping film such as a transparent film. Thereby, it becomes a tobacco product.

  Next, opening of the packaging container 1 configured as described above and opening and closing of the lid 6 will be described. First, the packaging container 1 wrapped with the outer packaging film is removed by opening the outer packaging film and moving away from the container 5. By the movement of the lid body 6, the indentation 71 of the hinge portion 7 is bent, and the rotation portion 31 is formed.

  Thereafter, when the lid body 6 is opened and closed, the rotating portion 31 becomes the rotation axis of the lid body 6, and the rotating portion 31 is bent so that the lid body 6 rotates. For this reason, by separating the lid body 6 from the storage body 5, the lid body 6 is pivoted around the pivoting portion 31, and the packaging container 1 can be opened and closed.

  As shown in FIG. 4, the packaging container 1 consumes several packaged cigarettes T, and a gap is generated between the cigarettes T and the packaging container 1. The lid 6 can be opened and closed with 31 as an axis. Hereinafter, the opening and closing of the lid body 6 by pressing the hinge portion 7 will be specifically described with reference to FIGS.

  As shown in FIG. 3, when the lid 6 is closed, the packaging container 1 is such that a part of the lower end of the second front wall 21 of the lid 6 is formed between the protruding portion 16 of the first front wall 11 and the inner body 9. It is sandwiched between the front inner wall 17. Thereby, the lid body 6 covers the upper open end of the storage body 5, the lid body 6 is fixed by the protruding portion 16 so as to prevent rotation, and the packaging container 1 is closed.

  When opening the packaging container 1 in such a closed state, first, the lid body 6 is slightly moved upward to open the second front wall 21 from the holding of the protruding portion 16 and the front inner wall 17. Next, the second guide part 33 is pressed below the pivot part 31 of the hinge part 7, preferably between the pivot part 31 and the first guide part 32 of the hinge part 7.

  Specifically, the first side wall 13 of the packaging container 1 is pinched with the thumb and middle finger of one hand, and the hinge portion 7 is pressed with the index finger.

  By the pressing of the hinge portion 7, the second guide portion 33 below the rotating portion 31 is bent toward the valley fold side, and the first guide portion 32 is bent toward the mountain fold side. At the same time, the rotating portion 31 is guided by the indentation 71 and the cutting portion 74 and bends to the valley fold side in the same manner as the first guide portion 32.

  Due to these bends, the rotation portion 31 and the first guide portion 32 are bent in the pressing direction. Specifically, as shown in FIG. 2, the pressed portion is bent between the rotating portion 31 and the first guide portion 32 due to the bending of the rotating portion 31 and the first guide portion 32, and the second guide portion 33. Are bent so that planes of symmetry are close to each other.

  Further, the second rear wall 22 bends so that the left and right surfaces of the second rear wall 22 protrude around the second guide portion 33 above the rotation portion 31 due to the bending of the rotation portion 31. . That is, the second guide portion 33 above the rotating portion 31 is guided to bend toward the mountain fold side and bends in the direction opposite to the pressing direction.

  By bending these parts, the lid body 6 is pivoted about the pivoting portion 31 while the second rear wall 22 is bent (curved), the lid body 6 is separated from the storage body 5, and the packaging container 1 is It becomes an open state. Note that the packaging container 1 can maintain an open state by continuously pressing the hinge portion 7.

  Next, when the pressing of the hinge portion 7 is released, the bent rotation portion 31 and the first and second guide portions 32 and 33 are restored, and the lid body 6 is rotated around the rotation portion 31 in the closing direction. To do. The hinge portion 7 is not completely restored since the dents (folds) are generated once the indentations 71, 72, 73 are bent. The lid 6 interferes with the inner body 9. For this reason, the lid 6 is not naturally closed by releasing the pressing of the hinge portion 7.

  Therefore, when the packaging container 1 is completely closed, the lid body 6 is directly rotated to cause the lid body 6 and the inner body 9 to interfere with each other, and a part of the lower end of the second front wall 21 protrudes. It is held between the part 16 and the front inner wall 17. As a result, the lid 6 is brought into contact with the upper end of the storage body 5 to close the opening of the storage body 5.

  According to the packaging container 1 configured in this manner, the first rear wall 22 is bent by pressing below the rotating portion 31 of the hinge portion 7, and the rotating portion formed obliquely by this bending. 31 bends, and the bend causes the lid 6 to pivot about the pivoting portion 31.

  Further, the hinge portion 7 has a configuration in which the first guide portion 32 is provided below the rotation portion 31 and the second guide portion 33 is provided on the center side of the rotation portion 31 and the first guide portion 32. The second guide portions 32 and 33 guide the bending more reliably, and the lid body 6 is reliably rotated.

  Next, a blank 2A forming such a packaging container 1A will be described. In addition, in FIG. 8, the chain line shows the broken line of blank 2A, and the thick line has shown the cut part, respectively.

  The blank 2A is a piece of material obtained by cutting a paper material into a shape in which the packaging container 1A is developed by punching. The blank 2 </ b> A includes a front surface 130, a pair of side surfaces 131, a rear surface 132, a bottom surface 133, and a top surface 134. Further, the blank 2A includes a first connection surface 135, a second connection surface 136, a third connection surface 137, a fourth connection surface 138, a fifth connection surface 139, a sixth connection surface 140, and a seventh connection surface. A connection surface 141.

  The front surface 130 is formed by indentations 145, 146, 147, 148 and a cutting portion 149 in a shape in which the first front wall 11A, the second front wall 21A, and the zipper portion 120 are continuous. In addition, the cutting | disconnection part 149 forms the external shape of the zipper part 120 by making continuous. The cutting portion 149 is formed in an arrangement and shape that can be cut when a unidirectional force is applied to the zipper portion 120.

  The pair of side surfaces 131 are provided adjacent to the front surface 130 via the indentations 145 and 147, respectively. The side surface 131 is formed in the shape of the first and second side walls 13A, 23A by the indentations 145, 149, 150, 151 and the indentations 147, 152, 153, 154. The side surface 131 has a plurality of cutting portions 155 that form the upper end of the first side wall 13A and the lower end of the second side wall 23A.

  The rear surface 132 is formed by indentations 150, 156, 157 and a cutting portion 157 in such a manner that the first and second rear walls 12A, 22A are continuous via the hinge portion 7A. The rear surface 132 has a hinge portion 7 </ b> A formed by the indentations 161 and 162 and a plurality of cutting portions 163. The indentation 161 is provided in the same shape as the rotation part 31 </ b> A, and the plurality of cutting parts 163 are formed by cutting a part of the indentation 161.

  The inclining angle of the indentation 161 and the cutting portion 163 that form the rotating portion 31A is formed to be substantially the same as that of the indentation 71 and the cutting portion 74 of the rotating portion 31 described above.

  The bottom surface 133 is provided, for example, adjacent to the front surface 130 via an indentation 148, and is laminated and bonded to the second to fourth connection surfaces 136 to 138 to form the bottom wall 14A of the packaging container 1A. It is made possible.

  The top surface 134 is provided, for example, adjacent to the front surface 130 via the indentation 146, and is laminated and bonded to the fifth to seventh connection surfaces 139 to 141, so that the top wall 24A of the packaging container 1A is adhered. It is formed so that it can be formed.

  The first connection surface 135 is provided adjacent to the one side surface 131 via the indentation 153 and is formed so as to be laminated with a part of the rear surface 132 so as to be bonded. When the first connection surface 135 is stacked on the rear surface 132, a cut or indentation is provided at a portion overlapping the indentation 161 provided on the rear surface 132.

  In the blank 2A configured as described above, each indentation except the indentations 161 and 162 forming the hinge portion 7 is folded in the same direction, and the bottom surface 133, the top surface 134, and the joining surfaces 135 to 141 are laminated by an adhesive. And the packaging container 1A is formed by being bonded.

  1 A of packaging containers comprised in this way cut | disconnect the zipper part 120, and rotate the cover body 6A in the direction which spaces apart from the storage body 5A, The cutting | disconnection part 155 fractures | ruptures, and the cover body 6A and the storage body 5A Are spaced apart from each other, and the indentation 161 of the hinge portion 7A is bent to form a rotating portion 31A. Thereafter, when the lid 6A is opened and closed, the rotating part 31 of the hinge part 7 is bent.

  Note that the packaging container 1A has the lid 6A with the pivoting part 31A as an axis by pressing the hinge part 7A or the first side wall 13A in the same manner as the packaging container 1A because the pivoting part 31A is bent once. Can be opened and closed.

  That is, the packaging container 1 </ b> A presses the second guide portion 33 below the rotating portion 31 </ b> A. For example, while holding the first side wall 13A of the packaging container 1A with the thumb and middle finger of one hand, the hinge part 7A is pressed with the index finger.

  By the pressing of the hinge portion 7A, the second guide portion 33A below the rotation portion 31A is bent toward the valley fold side, and the periphery of the second guide portion 33A is bent in the pressing direction, so that the rotation portion 31A will bend to the valley fold side.

  For this reason, in the rotation part 31A, as shown in FIG. 7, it bends so that a symmetrical surface may mutually adjoin centering on the 2nd guide part 33. As shown in FIG. Further, the second rear wall 22A rotated by the rotating portion 31A is bent so that the left and right surfaces of the second rear wall 22A protrude around the second guide portion 33A above the rotating portion 31A. . Accordingly, the lid body 6A rotates about the rotating portion 31A as a fulcrum while the second rear wall 22A is bent, like the lid body 6 of the packaging container 1 described above, and the lid body 6A is separated from the storage body 5A. The packaging container 1A is in an open state. In addition, 1 A of packaging containers can maintain an open state by maintaining the press of hinge part 7A.

  As described above, according to the packaging container 1 </ b> A according to the present embodiment, the hinge portion 7 </ b> A has the rotating portion 31 that is inclined obliquely downward as it goes toward the center side in the width direction W. Similarly to the packaging container 1 described above, the lid 6A is rotated by pressing the hinge portion 7A or pressing the first side wall 13A.

  The present invention is not limited to the above embodiment. For example, in the above-described example, the rotating portions 31 and 31A have been described as having the cut portions 74 and 163 in the indentations 71 and 161. However, the length and number of the cut portions 74 and 163 are the same as those of the blanks 2 and 2A. It can be set as appropriate depending on the paper material and dimensions, and a configuration in which the cutting part 74 is not provided may be employed.

  In particular, in the above-described example, the rotating portions 31 and 31A are set to 20 ° with respect to the ridge line with the second rear walls 22 and 22A and the top walls 24 and 24A, but the present invention is not limited thereto. This 20 ° is a dimension that provides a preferable opening when formed with the above dimensions and paper material, and can be appropriately set according to each dimension, paper material, and application. Similarly, the first guide portion 32 can be set as appropriate.

  Moreover, in the example mentioned above, in the packaging container 1, the structure which has the rotation part 31, the 1st guide part 32, and the 2nd guide part 33 as the hinge part 7 is rotated as the hinge part 7A in the packaging container 1A. Although the configuration including the portion 31A and the second guide portion 33A has been described, the configuration is not limited thereto. For example, the first guide unit may be provided without the second guide unit, or the rotation unit alone may be used. Furthermore, a configuration having the second guide part only above or below the rotation part 31 may be employed.

  However, each guide part guides the bending when the hinge part is pressed in order to bend the rotating part and rotate the lid, to partially concentrate the bending and increase the amount of bending. The hinge part has a large amount of bending around the hinge part 7, so that the amount of rotation of the lid body also becomes large.

  For this reason, when there are few guide parts, since a bending will disperse | distribute and a bending amount will reduce, the rotation amount of a cover body will reduce. However, the amount of rotation of the lid varies depending on the size and shape of the packaging container and the paper material, and the requirement for the degree of rotation of the lid also varies depending on the intended use. For this reason, each guide part provided in a hinge part can be suitably set with the use use of a packaging container, each dimension shape, a paper raw material, etc.

  Furthermore, in the example mentioned above, although it was set as the structure which provides each indentation as a folding line which guides bending in the blanks 2 and 2A, it is not limited to this. For example, when bending a blank with a blank manufacturing apparatus, it is not necessary to guide the folding line, and therefore, for example, it is not necessary to provide an indentation. In addition, various modifications can be made without departing from the scope of the present invention.
