  Conventionally, it has a cylindrical shape including a top plate, left and right side plates, and a bottom plate, and is bent into a V-shape inward in a longitudinal section across at least a part of the height direction of both side plates. A packaging cushioning material made of corrugated paper that can be bent and expanded vertically by elasticity is known (see, for example, Patent Document 1).

JP 2010-36925 A

  The cushioning material for packing described in Patent Literature 1 has a limited range of deformation and cannot sufficiently cope with changes in the number and size of the objects to be stored. The remaining space in the storage portion of the storage object varies depending on the shape of the storage object to be packed. Therefore, the cushioning material for packing needs to be newly designed according to what is packed, and there is a problem that the cost increases.

  An object of the present invention is to provide a packing cushioning material that can be freely changed in one direction.

  The packing cushioning material according to the present invention includes a rectangular first flat plate, a rectangular second flat plate facing the first flat plate, one end of the first flat plate, and one end of the second flat plate. Between the first side plate provided between the first flat plate, the other end of the first flat plate opposite to the one end and the other end of the second flat plate opposite to the one end. A first side end portion extending in a direction intersecting with the one end portion of the first flat plate, and a first side end portion, A second side end portion, a first bent portion formed in parallel with the one end portion of the first plane plate and bent inward of the square tube, and the second side end portion from the first side end portion side. A first notch part having a predetermined width and a predetermined length notched around the first bent part in the direction, and the second side plate faces the first side end of the first side plate First A side end and a fourth side end facing the second side end of the first side plate, and the other end of the first flat plate are formed in parallel and bent inward of the square tube. A second bent portion; and a second cutout portion in which the periphery of the second bent portion is cut out by a predetermined width and a predetermined length from the fourth side end portion toward the third side end portion, One bent part can enter the second notch part, and the second bent part can enter the first notch part.

  In this packing cushioning material, the packaging cushioning material is deformed so that the first flat plate and the second flat plate approach each other when the first bent portion and the second bent portion are bent inside the square tube. By changing the amount of bending of the first bent portion and the second bent portion, it can be changed to an arbitrary size. Moreover, since the 1st bending part and the 2nd bending part have spring property, the shock absorbing material for packing is excellent in impact resistance, and can play the role of a shock absorbing material. Further, since the first bent portion can enter the second cutout portion and the second bent portion can enter the first notch portion at all, the first flat plate and the second flat plate come close to each other for packing. The cushioning material can be deformed to a thin state. Therefore, the variable amount of the distance between the first flat plate and the second flat plate of the packing cushioning material can be increased. Therefore, a packing cushioning material that can be freely changed in one direction can be realized.

  In the packing cushioning material, one end of the first side plate is connected to the one end of the first flat plate, and the other end of the first flat plate is connected to the one end of the second flat plate. An end is connected, and on the inside of the first plane plate, a rectangular third plane plate is provided in parallel with the first plane plate, and one end of the third plane plate is the first plane plate Proximate to one end, the other end of the third plane plate opposite to the one end is adjacent to the other end of the first plane plate, and the other end of the second plane plate is The other end portion of the second side plate is connected to the other end portion of the third flat plate, and the one end portion of the second side plate is connected to the other end portion of the third flat plate.

  In this case, the outer shape of the cushioning material for packing is formed by the third flat plate overlapping the first flat plate. Moreover, since the one end part of the 3rd plane board is adjoining to the one end part of the 1st plane board, the part which the 3rd plane board overlaps with the 1st plane board can be taken large. Accordingly, the rigidity is increased in the overlapping portion, and it is prevented from being bent. Therefore, the strength of the entire packing cushioning material is increased.

  In the packing cushioning material, the packing cushioning material is formed of a corrugated cardboard plate, provided between at least one pair of surfaces facing each other in the thickness direction of the second flat plate, and extended in a certain direction. The crests and troughs are alternately arranged to further form a corrugated core, and the extending direction of the crests and troughs is the one end and the other end of the second flat plate It may be parallel to the part.

  In this case, the extending direction of the crest and trough of the core of the corrugated board is parallel to the one end and the other end of the second flat plate, so the one end and the other end of the second flat plate are bent. The rigidity in the direction can be increased.

  In the packing cushioning material, the length of the first notch is at least half of the length between the first side end and the second side end of the first side plate, The length of the second notch may be at least one half of the length between the third side end and the fourth side end of the second side plate.

  In this case, the first notch and the second notch are sized so that the first bent part can enter the second notch and the second bent part can enter the first notch. As a result, the first flat plate and the second flat plate approach and the packing cushioning material can be deformed to a thin state. Therefore, the variable amount of the distance between the first flat plate and the second flat plate of the packing cushioning material can be increased.

  Next, with reference to FIG. 5, the corrugated board 7 which developed the packing cushioning material 1 will be described. FIG. 5 shows the inner surface of the packing cushioning material 1 developed. The corrugated cardboard plate 7 having a substantially rectangular shape in plan view has a first flat plate 10, a first side plate 40, a second flat plate 20, a second side plate 50, and a third flat plate from the lower side to the upper side in FIG. The face plates 30 are arranged in a line. The first flat plate 10, the second flat plate 20, and the third flat plate 30 are each rectangular in plan view. The first side plate 40 has a substantially U shape rotated 90 degrees clockwise, and the second side plate 50 has a substantially U shape rotated 90 degrees counterclockwise. Between the first plane plate 10 and the first side plate 40, a crease 3 that is valley-folded in a direction orthogonal to the longitudinal direction of the corrugated board 7 is provided, and between the first side plate 40 and the second plane plate 20. Is provided with a crease 4 that folds in a direction orthogonal to the longitudinal direction of the corrugated board 7, and a valley between the second flat plate 20 and the second side face plate 50 in the direction orthogonal to the longitudinal direction of the corrugated board 7. A fold 5 is provided, and a crease 6 is provided between the second side plate 50 and the third flat plate 30 to fold the cardboard plate 7 in a direction perpendicular to the longitudinal direction.

  Further, the first side plate 40 is provided with a first bent portion 41 that is a crease that folds in a direction perpendicular to the longitudinal direction of the corrugated board 7, and the second side plate 50 has a longitudinal direction of the corrugated board 7. A second bent portion 51 is provided as a fold that folds in the orthogonal direction. Further, the first side face plate 40 is formed with a first notch 42 which is a notch having a rectangular shape in front view from the right side in FIG. Further, the second side plate 50 is formed with a second cutout portion 52 which is a cutout having a rectangular shape in front view from the left side in FIG. Accordingly, the corrugated board 7 is folded at the crease 3, the crease 4, the crease 5, and the crease 6, the first bent portion 41 and the second bent portion 51 are fold-folded, and the third flat plate 30 is changed to the first flat plate 10. When packed inside, the cushioning material 1 for packing, which is a front-view spindle-type square tube shown in FIGS. 2 to 4, is formed. What is necessary is just to determine the magnitude | size of the cardboard board 7 according to the magnitude | size of the cushioning material 1 for packing to form.

  As shown in FIG. 4, the length in the extending direction of the first bent portion 41 of the first notch portion 42 is the first side end portion 43 that is the width of the first side plate 40 and the second side portion 40. The length of the second notch 52 in the extending direction of the second bent portion 51 is the width of the second side plate 50 on the third side. There is more than half of the length between the end 53 and the fourth side end 54. Therefore, the first bent portion 41 can enter the second notch 52 and the second bent portion 51 can enter the first notch 42 at all.

  Next, storage of the tape cassette 90 and the packing cushioning material 1 in the cassette storage portion 102 of the case 100 will be described with reference to FIGS. 3 and 6 to 10. First, the case where one tape cassette 90 and the cushioning material 1 for packing are accommodated in the cassette accommodating part 102 is demonstrated with reference to FIG.3 and FIG.6. When one tape cassette 90 is stored in the cassette storage unit 102, the remaining space of the cassette storage unit 102 becomes large. Therefore, as shown in FIGS. 3 and 6, the packing cushioning material 1 with a small deformation amount is inserted. In this case, the first bent portion 41 and the second bent portion 51, which are folds of the corrugated board 7 of the packing cushioning material 1, are less bent due to the rigidity of the corrugated board 7. The distance to 20 becomes longer. Therefore, as shown in FIG. 3, the first bent portion 41 does not enter the second notch portion 52, and the second bent portion 51 does not enter the first notch portion 42 at all. The remaining space in which one tape cassette 90 is stored in the cassette storage unit 102 is filled with the packing cushioning material 1 as shown in FIG.

  Next, a case where the two tape cassettes 90 and the packing cushioning material 1 are stored in the cassette storage unit 102 will be described with reference to FIGS. When two tape cassettes 90 are stored in the cassette storage unit 102, the remaining space of the cassette storage unit 102 is less than half. Accordingly, as shown in FIGS. 7 and 8, the packing cushioning material 1 having a medium deformation amount is inserted. In this case, as shown in FIG. 8, the first bent portion 41 enters the second notch portion 52, and the second bent portion 51 enters the first notch portion 42 at all. The remaining space in which the two tape cassettes 90 are stored in the cassette storage unit 102 is filled with the packing cushioning material 1 as shown in FIG.

  Next, a case where three tape cassettes 90 and the cushioning material 1 for packing are stored in the cassette storage unit 102 will be described with reference to FIGS. 9 and 10. When three tape cassettes 90 are stored in the cassette storage unit 102, the remaining space of the cassette storage unit 102 is very small. Therefore, as shown in FIGS. 9 and 10, the packing cushioning material 1 whose deformation amount is greatly crushed is inserted. In this case, as shown in FIG. 10, the first bent portion 41 has entered deeply into the second cutout portion 52, and the second bent portion 51 has entered deeply into the first cutout portion 42. The remaining space in which the three tape cassettes 90 are stored in the cassette storage unit 102 is filled with the packing cushioning material 1 as shown in FIG.

  As described above, in the packing cushioning material 1 of the above embodiment, the first bent portion 41 can enter the second notch 52 and the second bent portion 51 can enter the first notch 42 at all. The first flat plate 10 and the second flat plate 20 approach each other, and the packing cushioning material 1 can be deformed to a thin state. Therefore, the variable amount of the distance between the first flat plate 10 and the second flat plate 20 of the packing cushioning material 1 can be increased. Therefore, the packing cushioning material 1 that can be freely changed in one direction can be provided. Moreover, since the 1st bending part 41 and the 2nd bending part 51 have spring property with the rigidity of the cardboard board 7, the cushioning material 1 for packing is excellent in impact resistance, and can fully fulfill | perform the role of a buffering material. Moreover, since the 3rd plane board 30 overlaps with the 1st plane board 10, the intensity | strength of the cushioning material 1 for packing goes up. Further, since the extending direction of the crests and troughs of the core 2 of the corrugated board 7 is parallel to the one end 21 and the other end 22 of the second flat plate 20, the one end 21 of the second flat plate 20. And the rigidity to the direction which bends the other end part 22 can be improved.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, when the second side plate 50 is viewed from the first side plate 40 even if the first cutout portion 42 and the second cutout portion 52 are not the same size, but one is larger and the other is smaller, It suffices if there is a range where the notch 42 and the second notch 52 overlap at all. Further, in FIG. 5, the first notch 42 may be cut out so as to reach the crease 3 and the crease 4. Similarly, the second cutout portion 52 may be cut out so as to reach the crease 5 and the crease 6. The packing cushioning material 1 can cope with not only the change in the number of tape cassettes 90 but also the change in the thickness of one tape cassette 90. In addition, the cushioning material 1 for packing can be used in order to fill the clearance gap between the storage parts of various things to be stored other than the above embodiment.
