  The present invention relates to a packaging box formed by punching a material such as corrugated cardboard with a wooden mold or the like and a manufacturing method thereof.

  A conventional packaging box is disclosed in Patent Document 1. This packing box is formed into a predetermined shape by punching a material made of corrugated cardboard or the like with a wooden mold or a metal mold and bending it. In the case of a large packaging box, it is necessary to increase the cost of the wooden mold and the like, so that the material such as cardboard is divided into two. FIGS. 10A and 10B show the first and second members punched in two.

  The first and second members 10 and 20 are formed in the same shape and have two side portions 11, 12, 21, and 22 each forming a side surface of the packaging box. Different decorations a and b are applied to the side surfaces 11 and 12 of the first member 10 and the side surfaces 21 and 22 of the second member 20.

  Upper flaps 13, 14, 23, and 24 are formed adjacent to one end of each of the side surfaces 11, 12, 21, and 22 to form the upper surface of the packaging box by bending. Lower flaps 15, 16, 25, and 26 are formed adjacent to the other ends of the side surfaces 11, 12, 21, and 22 to form the bottom surface of the packaging box by bending.

  On one side surface portion 11, 21 of the first and second members 10, 20, joint portions 17, 27 are formed adjacent to end portions in a direction orthogonal to the upper flaps 13, 23 and the lower flaps 15, 25. The Characters “A” and “B” representing the first and second members 10 and 20 are printed on the joint portions 17 and 27.

Next, as shown in FIG. 11, the joint portion 17 of the first member 10 and the side surface portion 22 of the second member 20 on the side where the joint portion 27 is not formed are joined by an adhesive or a staple. Similarly, the joint portion 27 of the second member 20 and the side surface portion 12 of the first member 10 on the side where the joint portion 17 is not formed are joined. And while bending between the side surface parts 11 and 12 and between the side surface parts 21 and 22, the upper flaps 13, 14, 23, and 24 and the lower flaps 15, 16, 25, and 26 are bent and the figure mentioned later.

  In addition, according to the present invention, since the identification marks of the packaging boxes of different models are arranged at different distances from the side surfaces, it is possible to more easily discriminate the combination of different models at the time of joining and inspection.

  Embodiments of the present invention will be described below with reference to the drawings. For convenience of explanation, the same parts as those of the conventional example shown in FIGS. 1 and 2 are perspective views of the packaging box according to the first embodiment as viewed from above and below. The packaging box 1 is formed by joining a first member 10 and a second member 20 in which a material such as corrugated cardboard is punched out with a wooden mold or a mold, and bending it at a predetermined position. Two different decorations a and b are applied to the side surface of the packaging box 1 by the first and second members 10 and 20. The bottom surface side of the packaging box 1 is closed by adhering an adhesive tape, and the upper surface side is closed by folding the first and second members 10 and 20 and fitting them.

  FIGS. 3A and 3B are plan views showing the first and second members 10 and 20. The first and second members 10 and 20 are formed in the same shape, and have two side portions 11, 12, 21, and 22 each forming two side surfaces of the packaging box 1. Different decorations a and b are applied to the side surfaces 11 and 12 of the first member 10 and the side surfaces 21 and 22 of the second member 20.

  Upper flaps 13, 14, 23, 24 that form the upper surface of the packing box 1 by bending are formed adjacent to one end of each of the side surfaces 11, 12, 21, 22. Lower flaps 15, 16, 25, and 26 that form the bottom surface of the packaging box 1 by bending are formed adjacent to the other ends of the side surfaces 11, 12, 21, and 22. On one side surface portion 11, 21 of the first and second members 10, 20, joint portions 17, 27 are formed adjacent to end portions in a direction orthogonal to the upper flaps 13, 23 and the lower flaps 15, 25. The

  The lower flaps 15 and 16 of the first member 10 are each provided with an identification mark 19a at one end on the side away from each other. The lower flaps 25 and 26 of the second member 20 are each provided with an identification mark 29a at one end on the side away from each other. The identification marks 19a and 29a have the same rectangular shape and are formed in different colors. The distance L1 between the identification mark 19a and the side surfaces 11 and 12 is the same as the distance L2 between the identification mark 29a and the side surfaces 21 and 22.

  As shown in FIG. 4, the first and second members 10 and 20 having the above-described configuration are formed by bonding the joint portion 17 of the first member 10 and the side surface portion 22 of the second member 20 on the side where the joint portion 27 is not formed. And are joined by staples. Similarly, the joint portion 27 of the second member 20 and the side surface portion 12 of the first member 10 on the side where the joint portion 17 is not formed are joined. And while bending between the side surface parts 11 and 12 and between the side surface parts 21 and 22, upper flaps 13, 14, 23, and 24 and lower flaps 15, 16, 25, and 26 are bent, and it is in FIG. A rectangular box 1 is formed.

  When joining the joint 17, the identification marks 19 a and 29 a formed on the adjacent lower flaps 15 and 26 are close to each other. When joining the joint portion 27, the identification marks 19a and 29a formed on the adjacent lower flaps 16 and 25 are close to each other. At this time, the identification marks 19a and 29a having the same shape have the same distances L1 and L2 from the side surface portions 11, 12, 21, and 22.

  For this reason, by joining the joining portions 17 and 27 so that the positions of the identification marks 19a and 29a coincide with each other, the positional deviation α (see FIG. 11) of the first and second members 10 and 20 can be easily performed. Can be reduced. Therefore, the defect rate of the packaging box 1 can be reduced. The identification marks 19a and 29a may be provided only on the lower flaps 15 and 26, or may be provided only on the lower flaps 16 and 25.

  Also, by confirming that the identification marks 19a, 29a of the same shape and different colors are close to each other, it is easily determined that the combination of the first and second members 10, 20 is correct, and the first, second members 10, 20 can be joined. Then, when the first members 10 are mistakenly joined or when the second members 20 are joined together, the color of the identification marks 19a and 29a can be visually recognized to easily determine the defect. Therefore, it is not necessary to grasp the decorations a and b, and the number of inspection steps can be reduced.

  The identification marks 19a and 29a have different colors, but may have different patterns. Furthermore, although the identification marks 19a and 29a are formed in a rectangle, other shapes such as a triangle may be used. At this time, for example, if the identification marks 19a and 29a are triangular, the alignment can be performed accurately if the vertexes are inverted so that the vertices face each other. Further, the identification marks 19a, 29a may be formed on the upper flaps 13, 14, 23, 24. However, it is more preferable to form the lower flaps 15, 16, 25, and 26 that are normally hidden when the packaging box 1 is installed because it does not impair the aesthetic appearance.

  Next, a description will be given of the case of manufacturing a multi-type packaging box in which the second and third packaging boxes (not shown) are added to the first packaging box 1 shown in FIG. FIGS. 5A and 5B are plan views showing the first and second members of the second packaging box, and FIGS. 6A and 6B are the first and second parts of the third packaging box. It is a top view which shows a member.

  The first and second members 10 ′ and 20 ′ of the second packaging box shown in FIGS. 5A and 5B are decorated on the side portions 11, 12, 21 and 22 with the decorations a and b of the first packaging box 1. Different decorations c and d are applied. The lower flaps 15, 16, 25 and 26 are provided with identification marks 19 b and 29 b having the same shape as the first packing box 1. The identification marks 19b and 29b are formed with different colors of the same shape. Furthermore, the distances L3 and L4 from the side surfaces 11, 12, 21, and 22 of the identification marks 19b and 29b are the same. The distances L3 and L4 are different from the distances L1 and L2 (see FIG. 3) from the side surfaces 11, 12, 21, and 22 of the identification marks 19a and 29a.

  The first and second members 10 "and 20" of the third packing box shown in Figs. 6A and 6B have decorations e and f different from the decorations a to d on the side surfaces 11, 12, 21, and 22. It has been subjected. The lower flaps 15, 16, 25, and 26 are provided with identification marks 19c and 29c having a shape different from that of the first packing box 1. The identification marks 19c and 29c are formed with different colors having the same shape.

  According to the above configuration, the positions of the identification marks 19b, 29b on the second packaging box are different from the identification marks 19a, 19c, 29a, 29c on the first and third packaging boxes. For this reason, for example, even if the first member 10 of the first packaging box 1 and the second member 20 ′ of the second packaging box are mistakenly joined, the positions of the identification mark 19a and the identification mark 29b are visually recognized at the time of inspection. Thus, it is possible to easily determine a defect.

  Further, the identification marks 19c, 29c of the third packing box are different in shape from the identification marks 19a, 19b, 29a, 29b of the first and second packing boxes. Therefore, for example, even if the first member 10 of the first packing box 1 and the second member 20 '' of the third packing box are mistakenly joined, the shapes of the identification mark 19a and the identification mark 29c are visually recognized at the time of inspection. Thus, it is possible to easily determine a defect.

  Therefore, it is not necessary to grasp the decorations a to f even when the number of packaging boxes is increased, and the number of inspection steps can be reduced.

  Next, a second embodiment will be described. This embodiment is different from the first embodiment shown in FIGS. 7A and 7B show the first and second members 10 and 20 of the first packing box. Characters 18 and 28 of “1A” and “1B” indicating the first and second members 10 and 20 of the first packing box are added to the identification marks 19a and 29a of the first and second members 10 and 20, respectively. ing.

  FIGS. 8A and 8B show the first and second members 10 ′ and 20 ′ of the second packing box. The identification marks 19b and 29b of the first and second members 10 ′ and 20 ′ include characters “2A” and “2B” 18 indicating the first and second members 10 ′ and 20 ′ of the second packaging box, 28 is added. The same applies to the third packing box. Other parts are the same as those in the first embodiment.

  According to the present embodiment, since the characters 18 and 28 indicating the first and second members of the packaging boxes of each model are added to the identification marks 19a to 19c and 29a to 29c, the first and second members are joined or joined. It is possible to more easily determine that the combination of the first and second members is correct at a later inspection. Therefore, it is possible to further reduce the packaging box defects and man-hours.

  Next, Fig.9 (a), (b) is a top view which shows the 1st, 2nd members 10 and 20 of the packaging box of 3rd Embodiment. The packing box of the present embodiment is configured such that the upper surface side and the bottom surface side are closed by sticking an adhesive tape. Other parts are the same as those of the first embodiment shown in FIGS. In this embodiment, the same effect as that of the first embodiment can be obtained.

  In the first to third embodiments, the divided first and second members 10 and 20 are joined to form a packaging box, but the packaging box is made by joining the members divided into three or more parts. In the case of forming, the same effect can be obtained by the same configuration.
