The side plate 22 has a rectangular flat plate shape similar to the side plate 18.

  The side plate 22 is connected to the side plate 16 by bonding an adhesive piece 40 connected to the left end side of the side plate 16 to the inner surface near the front end side of the side plate 22.

  A lid plate 12 is connected to the upper end of the side plate 16. The cover plate 12 is rotatably connected to the side plate 16. The lid plate 12 includes a main body 50, an engagement piece 52, a guide tape 54, an insertion hole 56, and two break start portions 58 and 58. The main body 50 has a substantially rectangular flat plate. The main body 50 is rotatably connected to the side plate 16 over the entire length in the left-right direction at the upper end side of the side plate 16. The main body 50 has the same length in the left-right direction as the bottom 24 and the side plate 16, and the length in the front-rear direction is shorter than the bottom 24 and the side plates 18, 22. The rear end of the main body 50 is located behind the center position of the bottom 24 and the side plates 18 and 22 in the front-rear direction.

  An engagement piece 52 is connected to the rear end side 50 a of the main body 50. The engagement piece 52 protrudes rearward from the front end side 50 b of the main body 50 at a part of the center in the left-right direction of the main body 50. The engagement piece 52 is shorter in the left-right direction at the end of the engagement piece 52 on the main body 50 side than the rear portion.

  A guide tape 54 is affixed to the inner surface of the main body 50. In FIG. 2, the guide tape 54 is shown on the outer surface of the main body 50 for the sake of explanation, but actually, the guide tape 54 is arranged at the position shown in FIG. 2 on the inner surface of the main body 50. . The guide tape 54 is disposed in the vicinity of the rear end side 50 a of the main body 50. The guide tape 54 is disposed in parallel to the rear end side 50a, that is, the left-right direction over the entire length in the left-right direction. Even when the guide tape 54 is applied in a direction parallel to the left-right direction by design, the guide tape 54 may not actually be applied in parallel due to an error in the application device.

  In the main body 50 in front of the guide tape 54, two fracture start portions 58 and 58 are disposed apart from the guide tape 54 in the front-rear direction. Each break start portion 58 includes a plurality of slits that are intermittently arranged on a straight line. In the present embodiment, the “slit” means a notch penetrating the plate, and means that the gap between the plates on both sides of the notch is not opened.

  The fracture start portions 58 are disposed at both the left and right ends of the main body 50. The right fracture start portion 58 extends from the right end side of the main body 50 toward the center in the left-right direction. The fracture start portion 58 is inclined rearward, that is, in a direction approaching the guide tape 54 with respect to the guide tape 54 from the right end side of the main body 50 toward the center. The left fracture start portion 58 extends from the left end side of the main body 50 toward the center in the left-right direction. The fracture start portion 58 is inclined rearward, that is, in a direction approaching the guide tape 54 with respect to the guide tape 54 from the left end side of the main body 50 toward the center. The fracture start portions 58 are disposed at both the left and right ends of the main body 50, but are not disposed at the central portion except for the left and right ends of the main body 50.

  In the main body 50, an insertion hole 56 is disposed in front of the guide tape 54 and the break start portion 58 and behind the front end side 50 b of the main body 50, that is, the boundary with the side plate 16. The insertion hole 56 is disposed slightly forward from the front end side of the lid plate 14 described later. The insertion hole 56 has an opening extending in the left-right direction at the center portion, and has a slit extending in the left-right direction at both left and right ends of the opening.

  A lid plate 14 is connected to the upper end of the side plate 20. The lid plate 14 is rotatably connected to the side plate 20. As shown in FIG. 1, when the packaging container 10 is closed, the cover plate 14 is disposed so as to overlap the cover plate 12. On the other hand, in a state where the packaging container 10 is opened, the rear end side 60b of the cover plate 14 is opposed to the front end side 50b of the cover plate 12 with an interval in the front-rear direction.

  The lid plate 14 has the same configuration as the lid plate 12. That is, the lid plate 14 includes a main body 50 of the lid plate 12, an engagement piece 52, a guide tape 54, an insertion hole 56, and a main body 60 corresponding to the two fracture start portions 58 and 58. The joining piece 62, the guide tape 64, the insertion hole 66, and the two fracture | rupture start parts 68 and 68 are provided.

  Each of the bent pieces 32 and 34 is rotatably connected to the upper ends of the side plates 18 and 22.

(How to open and close the packaging container)
Next, a method for opening and closing the packaging container 10 will be described with reference to FIGS. In the packaging container 10, the side plates 18 and 22 are first rotated from the state shown in FIG. Next, the cover plate 12 is first rotated with respect to the side plate 16, moved to a position overlapping the bent pieces 32 and 34 and facing the bottom portion 24. Next, the lid plate 14 is rotated with respect to the side plate 20 and is placed above the lid plate 12. Next, the engagement piece 62 of the lid plate 14 is inserted into the insertion hole 56. As a result, the engagement pieces 62 engage with the cover plate 12, and the cover plates 12 and 14 are closed as shown in FIG.

  In the opening at the center of the insertion hole 56, the length in the left-right direction is slightly longer than the short portion in the left-right direction located at the end of the engagement piece 62 on the main body 60 side. It is shorter than the long part in the left-right direction. Further, the total length in the left-right direction including the slits at both the left and right ends of the insertion hole 56 is longer than the portion extending in the left-right direction at the front end portion of the engagement piece 62. In this configuration, when the engagement piece 62 is inserted into the insertion hole 56, the engagement piece 62 widens the slit of the insertion hole 56 and passes through the insertion hole 56. When the engaging piece 62 is inserted into the insertion hole 56 up to a short portion in the left-right direction on the main body 60 side, the slit of the insertion hole 56 is closed. As a result, the engagement piece 62 is engaged with the slit of the insertion hole 56 on the inner surface side of the lid plate 12 and is maintained in a state where the lid plate 14 is not opened.

  As shown in FIG. 4, when opening the packaging container 10, the main body 60 of the cover plate 14 is broken along the breaking start portion 68 so that the broken portion 70 is separated from other portions of the main body 60. it can. A guide tape 64 is disposed on the lower surface of the fracture portion 70. For this reason, as shown in FIG. 5, by pulling the broken portion 70 together with the guide tape 64 from the main body 60, the main body 60 can be broken to the right end side without breaking the broken portion 70 halfway.

  As a result, the broken portion 70 can be separated from the main body 60 as shown in FIG. Thereby, the engagement piece 62 and the main body 60 can be separated and separated. According to this configuration, the broken portion 70 can be separated along the guide tape 64 by pulling the broken portion 70. Thereby, the packaging container 10 can be opened smoothly. In particular, by arranging the plurality of slits of the breaking start portion 68 so as to approach the guide tape 64 with respect to the guide tape 64, the broken portion 70 can be guided to the vicinity of the guide tape 64. Thereby, it can prevent that the fracture | rupture part 70 remove | deviates from the guide tape 64, and is cut | disconnected.

  Further, since the broken portion 70 is cut along the guide tape 64, it can be avoided that the main body 60 is broken apart from a portion other than the portion along the guide tape 64 by being detached from the guide tape 64.

  Furthermore, by disposing the guide tape 64, it is not necessary to dispose the slit for breaking, for example, the perforation, over the entire length of the main body 60 in the left-right direction. Thereby, it can avoid that the rigidity of the cover plate 14 falls. Further, when the engagement piece 62 is inserted into the insertion hole 56, it is possible to avoid the main body 60 from being bent at the breaking start portion 68.

  Further, a guide tape 64 is disposed in the vicinity of the front end side 60 a of the main body 60. For this reason, when the main body 60 is broken along the guide tape 64, the main body 60 on the rear side of the guide tape 64 may be broken. On the front end side 60a side of the guide tape 64, the engagement piece 62 is excluded, No need to break. Thereby, the force required to break the main body 60 can be reduced.

  In the blank BL of the packaging container 10, the cover plates 12 and 14 are located on the same side with respect to the side plates 16, 18, 20 and 22. In the blank BL, the guide tapes 54 and 64 are aligned on a straight line. For this reason, when affixing the guide tapes 54 and 64 on the blank BL, the guide tapes 54 and 64 can be affixed by arranging the tape on the blank BL in a straight line. Thereby, the work efficiency which arrange | positions the guide tapes 54 and 64 to the blank BL can be improved.

  The configuration “arranged on a straight line” includes not only a configuration arranged on a straight line in an actual blank BL but also a configuration arranged on a straight line in the blank BL in the design. That is, in the design, even if the guide tapes 54 and 64 are designed to be arranged in a straight line on the blank BL, due to the error of the attaching device for attaching the guide tapes 54 and 64, the actual blank BL is not necessarily The case where the guide tapes 54 and 64 are not arranged on a straight line is also included in the configuration “arranged on a straight line”. Further, in consideration of the error of the sticking device, a configuration in which the guide tapes 54 and 64 are arranged on the blank BL by shifting from the straight line in the design in advance is also included in the “placed on the straight line” configuration. In other words, the guide tapes 54 and 64 can affix the guide tapes 54 and 64 to the affixing device during the tape affixing operation without moving the blank BL in a direction other than the tape affixing direction. Placed in position.

  Further, since each of the main body 50 of the cover plate 12 and the main body 60 of the cover plate 14 is shorter than the bottom portion 24 in the front-rear direction, the main bodies 50, 60 have the same length as the bottom portion 24 in the front-rear direction of the bottom portion 24. Compared to the configuration, the blank BL can be made smaller.

  Furthermore, when the guide tapes 54 and 64 are arranged in the blank BL by making the length in the left-right direction of the bent pieces 32 and 34 shorter than the longitudinal direction of the main bodies 50 and 60, the bent pieces 32 and 34 It does not get in the way. In the modification, the length of the bent pieces 32 and 34 in the left-right direction may be longer than the length of the main bodies 50 and 60 in the front-rear direction. In this case, when arranging the guide tapes 54 and 64 in the blank BL, the tapes may be attached to the bent pieces 32 and 34 as well.

  As shown in FIG. 3, connecting portions 80 and 80 that connect the left and right ends of the cover plate 14 and the bent pieces 32 and 34 are arranged in the blank BL. In the connecting portions 80 and 80, when the lid plate 14 and the bent pieces 32 and 34 are separated from each other on the flat plate, the lid plate 14 and the bent pieces 32 and 34 are connected without separating only the connecting portions 80 and 80. Has been.

  The packaging container 10 is manufactured in a direction in which each of the irregularities of the cardboard paper extends in parallel to the height direction of the packaging container 10. When folding from the blank BL at the boundary between the side plates 16, 18, 20, and 22, it is possible to prevent the folding curve from being shifted due to the influence of the corrugated cardboard paper.

  As shown in FIG. 7, after the lid plate 14 is broken and the packaging container 10 is opened, when the object is accommodated again using the packaging container 10, the lid plate 12 is placed above the lid plate 14 after the fracture. The packaging container 10 can be reused by stacking the engaging pieces 52 into the insertion holes 66 of the lid plate 14. For example, it is useful when the packaging container 10 is used for reciprocal delivery. Furthermore, when the lid plate 14 is broken, the main body 60 does not need to be largely damaged, and therefore the insertion hole 66 is damaged and the engagement piece 52 cannot be properly engaged with the main body 60. .

  In order to open the packaging container 10 from the state where the lid plate 12 is disposed upward and closed, the main body 50 is broken along the breaking start portions 58 at the left and right ends of the main body 50. Thereby, the main body 50 is broken so that the engagement piece 52 is separated from the main body 50. According to this configuration, the lid plate 14 can achieve the same effect as when the packaging container 10 is opened by breaking the main body 60 such that the engagement piece 62 is separated from the main body 60.
