However, the packaging container of the present invention is not limited to a quadrangle such as a substantially square, a rectangle, or a rhombus, but may be a polygon such as a triangle or a pentagon. In addition, the first side wall part 11a, the second side wall part 11b, the third side wall part 11c, and the fourth side wall part 11d have an opening, and a translucent resin film is attached to the opening to transmit the light. The contents may be confirmed through the conductive resin film.

  An upper lid portion 12 is provided on any one of these side wall portions. In the illustrated embodiment, the upper lid portion 12 is connected to the upper edge of the third side wall portion 11c. The upper lid part 12 is connected to an edge part opposite to the edge part connected to the third side wall part 11c, and is provided with a tongue part 12a. The upper lid portion 12 may have a portion that forms a hanging portion for display.

  Moreover, the bottom cover part 13 is provided in any one side wall part of these side wall parts. In the illustrated embodiment, the bottom cover portion 13 is provided so as to be connected to the lower end of the first side wall portion 11a. A tongue 13a is provided on the bottom lid 13 so as to connect to the edge opposite to the edge connected to the first side wall 11a.

  Further, in the illustrated embodiment, middle lid portions 14 and 15 are provided respectively connected to the upper edges of the second side wall portion 11b and the fourth side wall portion 11d adjacent to the third side wall portion 11c, respectively. Inner lid portions 16 and 17 are provided to connect to the lower edges of the second side wall portion 11b and the fourth side wall portion 11d, respectively.

An adhesive margin 18 is provided so as to be connected to the side end of the first side wall 11a. A space between the first side wall portion 11a and the adhesive margin portion 18 is bent linearly by a fold line L4. The folding lines L1 to L4 may be assembled in a mountain fold or may be assembled in a valley fold.
The glue margin 18 is formed by bending the first side wall part 11a to the fourth side wall part 11d along the folding lines L1 to L4 and assembling them into a box-shaped container. The surface facing the internal space is referred to as the “rear surface”) and is the portion that is in contact with the superimposed surface. A bonding material such as glue is at least partially attached to either or both of the front surface of the margin portion 18 and the rear surface of the fourth side wall portion 11d, and the front surface of the margin portion 18 and the rear surface of the first side wall portion 11a. By overlapping and pressing, the margin portion 18 and the first side wall portion 11a are bonded. Instead of adhesion with a bonding material such as glue, adhesion with a double-sided adhesive tape may be performed.

  A linear folding line between the margin portion 18 and the first side wall portion 11a corresponds to a corner portion of the packaging container 10. A notch 19 is formed on the first side wall 11a side of the linear fold line between the glue margin 18 and the first side wall 11a. The cut 19 is formed between the upper end and the lower end of the first side wall portion 11a, and more specifically, is formed in the central portion that bisects the upper end and the lower end of the first side wall portion 11a. Further, the notch 19 is formed substantially parallel to a linear folding line between the margin portion 18 and the first side wall portion 11a. Although the length of the cut 19 depends on the size of the packaging container, it is about 5 mm to about 15 mm, and about 10 mm in the illustrated example. As shown in FIG. 2, the cut 19 is for forming a protrusion 20 at the corner of the glue margin 18 and the first side wall 11 a, and the cut 19 corresponding to the tip of the protrusion 20 is the user's The length that can be caught by the fingertip can be set to the above length.

  The notch 19 can be formed at a position about 1 mm away from the linear folding line between the adhesive margin portion 18 and the first side wall portion 11a toward the first side wall portion 11a. The distance of the notch 19 from the bend line corresponds to the height of the protrusion 20 in FIG. Therefore, the notch 19 corresponding to the tip of the protrusion 20 can be set to the above distance as a height that can be caught by the fingertip of the user.

  A first perforation 21 is formed at the glue margin 18 by connecting to one end of the notch 19, and a second perforation 22 is formed at the glue margin 18 by connecting to the other end of the notch 19.

  The first perforation 21 is connected to one end of the notch 19 and extends on a linear bending line between the glue margin 18 and the first side wall 11a, and the first straight line 21a And a second linear portion 21b extending in a direction inclined from the extending direction of the first linear portion 21a. The second straight portion 21b extends to the end of the margin allowance 18, in the illustrated example, to the longitudinal end of the margin allowance 18. The angle formed by the extending direction of the first straight part 21a and the extending direction of the second straight part 21b is preferably an obtuse angle.

  The second perforation 22 is connected to one end of the notch 19 and extends on a linear bending line between the glue margin 18 and the first side wall 11a, and the first straight portion 22a And a second linear portion 22b extending in a direction inclined from the extending direction of the first linear portion 22a. The second straight line portion 22b extends to the end of the margin allowance 18, and to the longitudinal end of the margin allowance 18 in the illustrated example. The angle formed by the extending direction of the first straight part 22a and the extending direction of the second straight part 22b is preferably an obtuse angle.

  The margin portion 18 is divided into three regions by a first perforation 21 and a second perforation 22. Among these regions, the region surrounded by the upper end of the glue margin 18, the second straight portion 21 b of the first perforation 21 and the folding line is defined as a first region 18 a, and the second straight line of the first perforation 21 A region sandwiched between the portion 21b and the second straight portion 22b of the second perforation 22 is defined as a second region 18b, and the lower end of the glue margin 18 and the second straight portion 22b of the second perforation 22 and the folding line A region surrounded by is defined as a third region 18c. A bonding material such as glue for bonding the margin portion 18 and the back surface of the fourth side wall portion 11d is attached only to the second region 18b, and is not attached to the first region 18a and the third region 18c. .

  In FIG. 2 which shows the perspective view of the packaging container 10 of this embodiment, the notch 19 protrudes at the corner as the tip of the protrusion 20. Therefore, when the packaging container 10 is unfolded, the user can open the corner portion by hooking his / her finger on the protrusion 20 and peeling the fourth side wall portion 11d from the first side wall portion 11a starting from the protrusion 20. .

  In addition, the first straight portion 21a of the first perforation 21 is connected to one end of the notch 19 and the first straight portion 22a of the second perforation 22 is connected to the other end. When the packaging container 10 is unfolded, the perforation is easily broken along the first straight portion 21a and the first straight portion 22a formed at the corners, the tears at the corners are enlarged, and the adhesive margin 18 And the first side wall portion 11a are easily separated.

  Furthermore, since the second straight line portion 21b is connected to the first straight line portion 21a of the first perforation 21, and the second straight line portion 22b is connected to the first straight line portion 22a of the second perforation 22, respectively. When the user unfolds the packaging container 10, the second straight portions 21 b and 22 b are easily broken following the perforation of the first straight portions 21 a and 22 a, and the tear is expanded so as to cross the adhesive margin 18. Thus, separation of the glue margin 18 and the first side wall 11a is facilitated.

  Since the glue margin 18 has glue or the like formed only in the second region 18b, after the perforation of the second straight portion 21b and the second straight portion 22b is broken by the development of the packaging container 10 by the user. The second region 18b remains on the back surface of the fourth sidewall portion 11d, and the first region 18a and the third region 18c are connected to the first sidewall portion 11a.

  Therefore, the packaging container 10 is separated along the notch 19, the first perforation 21 and the second perforation 22, and can be easily developed, so that a character message or the like written on the back surface can be easily obtained. I can read it.

  Moreover, the 1st perforation 21 and the 2nd perforation 22 for developing the packaging container 10 are formed in the glue margin part 18, and are formed in the 1st side wall part 11a-the 4th side wall part 11d. Therefore, the tear when the container is deployed does not reach the first side wall part 11a to the fourth side wall part 11d. Therefore, it can be avoided that the character messages written on the back surfaces of the first side wall part 11a to the fourth side wall part 11d are partially difficult to read.

  Moreover, since the 1st straight line part 21a of the 1st perforation 21 and the 1st straight line part 22a of the 2nd perforation 22 are extended along the bending line of a corner | angular part, it is the 2nd of the paste margin parts 18. A sufficient area of the region 18b can be secured. Therefore, it is possible to sufficiently secure the adhesive strength due to the adhesive adhered to the second region. In other words, there is no need to worry about a decrease in the adhesive strength as compared with the conventional packaging container.

  The second straight line portion 21b of the first perforation 21 is connected to the first straight line portion 21a at an obtuse angle. Similarly, the second straight line portion 22b of the second perforation 22 is connected to the first straight line portion 22a. On the other hand, since the connection is made at an obtuse angle, the rift extending from the first straight portions 21a and 21a easily moves to the second straight portions 21b and 22b. In addition, it is easy for the perforation to connect at an obtuse angle, while ensuring a sufficient area of the second region 18b of the margin part 18, separation between the first region 18a and the second region 18b, and the second region Separation between 18b and the third region 18c is ensured.

  The packaging container 10 of this embodiment is comprised from one sheet | seat (blank) so that it may become clear also from the expanded view of FIG. This sheet is typically made of paper, but is not limited to paper, and may be a plastic or a laminate.

  The method for assembling the packaging container 10 according to the present embodiment shown in FIGS. 1 and 2 includes a step of processing the sheet into a blank shape of the development view shown in FIG. 1 and a folding line according to the development view shown in FIG. A step of forming or folding, and a step of bonding the margin portion 18 and the first side wall portion 11a with glue (adhesive). These steps are not limited to the order of the steps described above. The step of bonding the margin portion 18 and the first side wall portion 11a with glue includes attaching glue to one or both of the margin portion 18 and the first side wall portion 11a. These processes can be performed with a box making machine. The packaging container of the present embodiment can be manufactured by a box making machine, and thus manual operation is not required due to automation by the box making machine.

  The packaging container 10 of the present embodiment can be flattened and folded in a flat state when not in use, and therefore does not become bulky during storage and transportation of the packaging container 10 itself.

  The packaging container of the present invention is not limited to the embodiment shown in FIG. 1 and FIG. 2, and various modifications are possible without departing from the spirit of the present invention. For example, the notch 19 is not limited to the one located at the central portion between the upper end and the lower end of the first side wall portion 11a, and may be formed at a position closer to the upper side or lower side than the central portion. In addition, when the first straight line portion 21a of the first perforation 21 and the first straight line portion 22a of the second perforation 22 are located on the bend line between the first side wall portion 11a and the adhesive margin portion 18.
