  A method for manufacturing the packaging container 10 will be described. In the following description of the manufacturing method, F of the arrow in FIG. 3 is front, B is rear, R is right, L is left, U is up, and D is down.

  From the state of FIG. 3 with the bubble cushioning material 40 on top and the paper 20 on the bottom, the peripheral wall portions 64 and 65 are integrated with the contact pieces 76 and 77 as shown in FIG. The bent pieces 72, 73, 74, and 75 are bent so as to be orthogonal to the peripheral wall portions 64 and 65 and orthogonal to the bottom wall portion 61 (along the left-right direction). .

  Then, as shown in FIG. 5, the peripheral wall portions 62, 63 are bent upward so as to be orthogonal to the bottom wall portion 61, and the upper edge portions 66, 67 are further back and forth with respect to the peripheral wall portions 62, 63. The flap portions 68 and 69 are bent so as to be orthogonal to each other, and the flap portions 68 and 69 are bent downward so as to be orthogonal to the upper edge portions 66 and 67. Then, the locking piece 70 is inserted into the locking hole 61a and the locking piece 71 is inserted into the locking hole 61b from above, and locked. Thereby, the state by which the surrounding wall part 62, the surrounding wall part 63, the upper edge parts 66 and 67, and the flap parts 68 and 69 were bent is maintained.

  At this time, the bent pieces 72 and 73 are sandwiched between the peripheral wall portion 62 and the flap portion 68, and the bent pieces 74 and 75 are sandwiched between the peripheral wall portion 63 and the flap portion 69 to restrict movement, and accordingly, the peripheral wall The state where the parts 64 and 65 are bent is also maintained.

  The contact pieces 76 and 77 are folded in a bellows so as to form two ridges on the upper side along a broken line indicated by a broken line, and are folded outward so as not to shield the opening 15a, thereby completing the packaging container 10. .

  In the present embodiment, the bottom wall portion 61 corresponds to the bottom wall portion of the main body of the claims (referred to as the bottom wall portion 151), the peripheral wall portions 62, 63, 64, 65, the upper edge portions 66, 67, The flap portions 68 and 69, the locking pieces 70 and 71, and the bent pieces 72, 73, 74, and 75 correspond to the peripheral wall portion of the main body of the claims (referred to as the peripheral wall portion 152).

  In other words, other than the contact pieces 76 and 77, the bottom wall portion 61, the peripheral wall portions 62, 63, 64, 65, the upper edge portions 66, 67, the flap portions 68, 69, the locking pieces 70, 71 and the bent pieces 72, 73, 74, 75 constitute the main body 15.

  A usage mode of the packaging container 10 will be described. The to-be-contained object W is an industrial product provided with an electronic component as shown in FIGS. 7 and 9, and has a shape in which the top in the longitudinal direction of the ellipse is cut off when viewed from the opening 15a side of the main body 15 in the accommodated state. The central portion Wa in the longitudinal direction of the object W is wide and formed so as to become narrower from the central portion Wa in the longitudinal direction of the object W toward the end Wb. And the thickness of the direction which goes to the bottom wall part 61 from the opening part 15a of the to-be-contained object W is made substantially the same.

  As shown in FIG. 6, the contact pieces 76 and 77 are bent, and the object W is accommodated between the contact pieces 76 and 77 in the main body 15 as shown in FIGS.

  At this time, as shown in FIGS. 7 and 9, the contact pieces 76 and 77 are in a state in which the vicinity of the center in the longitudinal direction is in contact with the vicinity of the center portion Wa of the wide object W and is strongly bent. Become. In addition, the contact pieces 76 and 77 are in a state where both end portions in the longitudinal direction are in contact with the narrow end portions Wb and Wb of the object W and are weakly bent. (This state corresponds to the contact means in the claims).

  In the bent contact pieces 76 and 77, as shown in FIG. 8, a portion where the bubble cushioning material 40 is folded is formed, and the bubble cushioning material 40 is elastically deformed to return to its original shape. The pieces 76 and 77 urge the object W toward the opposite peripheral wall portions 64 and 65, respectively. In particular, the bubble portion 40b1 is largely affected by the elastic deformation and the action of restoring the original shape.

  Moreover, in the to-be-contained object W of this embodiment, since it is a shape which becomes line symmetrical in a transversal direction when it sees from the opening part 15a side, the mutual urging | biasing force of a pair of contact piece 76 and 77 balances. The position of the object W is not biased to any end side in the short direction of the main body 15. Therefore, the object W is prevented from hitting the inner side of the peripheral wall portions 64 and 65.

  In other words, the abutting pieces 76 and 77 correspond to the shape of the object to be accommodated W due to the elastic deformation of the bubble cushioning material 40, and restrict the movement of the object to be accommodated W within the main body 15. Prevent W from being damaged.

  The object W is in contact with the flap portions 68 and 69 at the end portions Wb and Wb in the longitudinal direction, but the bubble cushioning material 40 is provided inside the paper 20 constituting the peripheral wall portions 62 and 63 and the flap portions 68 and 69. Is attached and elastically deformable, and the peripheral wall portions 62 and 63 and the flap portions 68 and 69 function as a buffer, so that the object W is not damaged.

  8 and 8, since the bubble cushioning material 40 is also attached to the inside of the bottom wall portion 61 and the peripheral wall portions 64 and 65, the object W is not damaged. .

  Further, since the paper 20 that is harder than the bubble cushioning material 40 gives rigidity to the contact pieces 76 and 77, compared to the case in which the contact pieces 76 and 77 are configured by only the bubble cushioning material 40, the paper is harder in the main body 15. The operation of accommodating the object W is facilitated.

  From the above, the packaging container 10 can be transported without restricting the movement of the object W within the main body 15 without damaging the object W.

  In the packaging container 10 having the above-described configuration, a cylindrical peripheral wall portion 152 (peripheral wall portions 62, 63, 64, 65, upper edge portions 66, 67, flap portions 68, 69, locking pieces 70, 71, bent pieces 72, 73, 74, 75) and a bottom wall portion 151 (bottom wall portion 61) that closes one end of the peripheral wall portion 152, the main body 15 is configured, and a packaging container in which the article W is stored in the main body 15. The contact pieces 76 and 77 are provided as contact means that extend from the main body 15 and come into contact with the object W. The contact pieces 76 and 77 are bubble cushions as elastically deformable buffer members. When the material 40 and the paper 20 that is harder than the bubble cushioning material 40 as the base material are overlapped, the contact pieces 76 and 77 are formed, and the object W is accommodated in the main body 15. The contact pieces 76 and 77 are in contact with the object W in a folded state. To.

  According to this, the abutting pieces 76 and 77 as the abutting means correspond to the shape of the object W to be accommodated by the elastic deformation of the bubble cushioning material 40 as the cushioning member after holding the shape by the paper 20. The movement of the object W within the main body 15 can be restricted to prevent the object W from being damaged.

  In addition, since the bubble cushioning material 40 is attached at least to the inside of the main body 15, the object W is damaged by combining the contact pieces 76 and 77 and the bubble cushioning material 40 in a composite manner. It contributes to preventing it.

  In addition, since the bubble cushioning material 40 is used as the cushioning member and the paper 20 is used as the base material, the object to be accommodated is combined with the elastic deformation force caused by the bubbles of the bubble cushioning material 40 and the shape retaining force of the paper 20. The manufacturing cost can be reduced after exerting the urging force to W and the effect as a buffer.

  In addition, since the contact pieces 76 and 77 as contact means are formed by accordion folding, the contact means can be formed relatively easily compared to other folding methods, and handling is easy. Can be.

  The packaging container of the present invention is not limited to the above configuration. That is, various design changes can be made without departing from the gist of the present invention.

  For example, although the bubble cushioning material 40 is stuck on one side of the paper 20, the bubble cushioning material 40 can be stuck on both sides of the paper 20. With such a configuration, it is possible to easily dispose the bubble cushioning material 40 in a portion that is in contact with the object W inside the main body 15 and a portion that is outside the main body 15. And when conveying in the state which the packaging containers 10 contact | connect, the to-be-contained object W can be prevented from being damaged even if the packaging containers 10 collide by the bubble cushioning material 40. FIG.

  Moreover, although the main body 15 of the packaging container 10 has a rectangular parallelepiped shape, it can be appropriately changed such as a cylindrical shape, an elliptical cylindrical shape, a long cylindrical shape, or a polygonal cylindrical shape with one end side closed.

  Further, although the contact pieces 76 and 77 are extended from the peripheral wall portions 64 and 65, it is possible to extend from other portions constituting the main body 15 such as the bottom wall portion 61 and the peripheral wall portions 62 and 63.

  In addition, although two contact pieces 76 and 77 as contact means are provided, depending on the shape and usage of the packaging container 10, one or a plurality other than two may be provided. it can.

  In addition, the folding method of the contact pieces 76 and 77 is two accordion folds, but existing fold processing such as accordion folds, heading folds, shifted accordion folds, etc. in which the number of ridges is changed is applied. be able to.

  In addition to paper, the base material of the packaging container 10 may be cardboard, wood, an elastomer plate, a composite material containing these, or the like.

  Moreover, although the main body 15 is formed by bending paper, the main body 15 can be integrally formed by die processing using synthetic resin or the like.

  Further, as the buffer member, a two-layer bubble buffer material or a sponge-like sheet can be used.

  Moreover, the to-be-contained object W can select suitably industrial products, a cracked thing, etc. of shapes other than the shape mentioned above. Even in such a case, the elastic deformation of the bubble cushioning material 40 as the buffer member corresponds to the shape of the object to be accommodated W, and the movement of the object to be accommodated W within the main body 15 is restricted to be accommodated. It is possible to prevent the article W from being damaged.
