  However, even when the protective member described in Patent Document 1 is mounted on the container body, the impact load from the corner of the panel of the packaged object may act on the corner of the container body, In order to maintain the shape, it is important to reduce the impact load acting on the corner of the container body.

  The present invention has been made in view of such a point, and the object of the present invention is that an impact load is applied to the corner of the panel of the package object in a state where the package object is packed with the packing material. Even if it is a case, it is providing the packing material which can reduce the impact load to the corner part of a container main body.

  As a result of intensive studies, the inventors have deformed so as to absorb the impact load when the impact load is applied to the corner of the panel of the package in a state where the package is packed with the packing material. New knowledge was obtained that the impact load on the corners can be reduced by providing the structure at the corners of the container body.

  The present invention is based on this new knowledge, and the packing material according to the present invention is a packing material for packing an object to be packed in which a circuit board is connected to a side portion of the panel via a flexible circuit. The packing material includes a container body in which a storage recess for storing an object to be packed is formed, and a lid that covers the container body so as to seal an opening formed in the storage recess. The housing recess is formed with a substrate housing recess for housing the circuit board of the article to be packed, and the container is formed at a corner of the housing recess on the side where the substrate housing recess is formed. A protective member that is detachably fitted to the main body and that protects a corner portion of the panel of the packed object is provided, and a fitting concave portion that is fitted to the protective member is formed at the corner portion. And the protective member is fitted into the fitting recess. In this state, a rib projecting from the side wall portion of the container body toward the protection member is formed so that the front end surface contacts the protection member, and the protection member is fitted into the fitting recess. In this state, the rib is provided so that the substrate receiving recess is located on one side of the both sides of the rib and the gap is formed on the other side. To do.

  According to the present invention, when packing an object to be packed, the objects to be packed are stacked in the storage recess so that the circuit board of the object to be packed is released into the substrate storage recess. At this time, the corner portions of the stacked panels of the objects to be packed can be protected by fitting the protective members into the fitting recesses formed in the corner portions of the container body.

  Here, in a state where the protective member is fitted in the fitting recess, a rib protruding from the side wall portion of the container main body toward the protective member is formed on the container main body, and the tip end surface of the rib contacts the protective member. ing. Thereby, the impact load from the corner | angular part of the panel which acts on a protection member can be received by the front end surface of a rib.

  Further, in a state in which the protective member is fitted in the fitting recess, the rib is formed so that the board housing recess is located on one side and the gap is formed on the other side of the rib. Since it is formed, the rib is easily deformed as compared with other corner portions. Thereby, the impact energy from the corner | angular part of the panel which acts on a protection member can be absorbed by deformation | transformation of a rib. As a result, the impact load on the corner of the container body can be reduced even when an impact load is applied to the corner of the panel of the package in a state where the package is packed with the packing material. Can do.

  As a more preferable aspect, in a state where the protective member is fitted in the fitting concave portion, the protective member extends further to the substrate housing concave portion side than the tip end surface of the rib. According to this aspect, since the corner of the panel of the article to be packed can be protected at the position extending further toward the substrate housing recess than the front end surface of the rib, the corner of the panel of the article to be packed is protected. This is effective when the space to be used is small. Further, the portion extending further to the substrate housing recess side than the tip surface of the rib is not in contact with the tip surface of the rib, so when an impact load is applied, this portion bends and absorbs the impact energy. be able to.

  As a more preferred embodiment, the fitting recess communicates with the storage recess, extends in a first direction, communicates with the first fitting recess, and the first direction. A second fitting recess extending in the intersecting second direction is formed, and the protection member is fitted into the first and second fitting recesses.

  According to this aspect, the first fitting concave portion and the second fitting concave portion constituting the fitting concave portion extend in different directions, and the protective member is fitted and restrained in these directions. Even if the protective member acts on the protective member, the protective member can be prevented from rotating or moving.

  As a more preferred aspect, the rib has a reduced thickness as it proceeds from the base end portion of the rib to the distal end surface of the rib. According to this aspect, the thickness of the rib decreases as it proceeds from the base end portion of the rib that supports the impact load acting on the rib to the distal end surface of the rib that directly receives the impact load acting on the rib. Therefore, it is possible to prevent the rib from being damaged by the impact load and to suitably deform the rib.

  As another more preferable aspect, the rib has a portion where the thickness of the rib is reduced between a base end portion of the rib and the tip end surface of the rib. According to this aspect, when an impact load is applied, the rib is easily deformed in a portion where the thickness of the rib is reduced, so that the shock energy is easily absorbed by the rib.

  As a more preferable aspect, a thinned portion is formed on the rib. According to this aspect, the ribs can be easily deformed by the impact load by providing the rib portions on the ribs.

  According to the present invention, even when an impact load is applied to the corner of the panel of the packed object in a state where the packed object is packed with the packing material, the impact load to the corner of the container body is reduced. be able to.

The protective member 30 ′, the fitting recess 25 ′, and the protective member 30 ′ shown in FIG. 1 have substantially the same configuration as that described in Patent Document 1 described above, and thus detailed description thereof is omitted.

  As shown in FIG. 3, in the present embodiment, a fitting recess 25 that fits into the protection member 30 is formed in the corner portion 21 d. At the corner 21d, the front end surface 26a is in contact with the protective member 30 (specifically, a fitting portion 33 described later) in a state where the protective member 30 is fitted in the fitting recess 25 in plan view. A rib 26 protruding from the side wall 24 of the container body 20 toward the protection member 30 is formed.

  In the present embodiment, as shown in FIG. 3, the substrate housing recess 21 c is provided on one side (inside the container body 20) of both sides of the rib 26 with the protective member 30 fitted in the fitting recess 25. The rib 26 is provided so that the space | gap part 27 may be formed in the other side (outside of the container main body 20). That is, the rib 26 has a structure that can be deformed independently of the other portions of the corner 21d by providing the gap 27.

  The fitting recess 25 includes a first fitting recess 25a that communicates with the storage recess 21 in a plan view and extends in the first direction with the longitudinal direction of the container body 20 as the first direction. Further, the fitting recess 25 communicates with the first fitting recess 25a and extends in a second direction intersecting the first direction (specifically, the short direction of the container body 20 perpendicular to the first direction). An extending second fitting recess 25b is formed.

  Specifically, as shown in FIG. 3, the second fitting recess 25b extends from the end of the first fitting recess 25a to both sides along the longitudinal direction. In the present embodiment, the second fitting recess 25 b communicates with the gap 27, and the fitting recess 25 and the gap 27 are integrally formed when the container body 2 is molded.

  The protection member 30 according to the present embodiment is a member that protects each corner portion Pc of the panel Pa on the side to which the circuit board Pb on the long side is connected when the article P is packed. Specifically, each protection member 30 includes a protection member main body 31 and an impact cushioning material 32 (see FIGS. 2 and 3).

  In the protective member main body 31, the housing recess 21 is formed from the fitting portion 33 that fits into the fitting recess 25 of the container body 20 and the corner 21 d of the housing recess 21 in a state in which the fitting portion 33 is fitted. A pair of arm portions 34, 34 formed integrally with the fitting portion 33 is formed so as to extend to each inner wall surface. The shock absorbing material 32 is disposed on the surface of each arm portion 34, 34 so as to protect the corner portion Pc of the panel Pa through, for example, an adhesive or an adhesive sheet.

Sometimes, the corner portion Pc can be protected by contacting the shock absorbing material 32 of the protection member 30.

  Here, in the state in which the protective member 30 is fitted in the fitting recess 25, the container body 20 is formed with ribs 26 that protrude from the side wall 24 of the container body 20 toward the protective member 30. The front end surface 26 a is in contact with the protection member 30. Thereby, the impact load from the corner | angular part Pc of the panel Pa which acts on the protection member 30 can be received by the front end surface 26a of the rib 26.

  Further, in the present embodiment, in the state where the protective member 30 is fitted to the fitting recess 25 in the rib 26, the substrate housing recess 21 c is located on one side of both sides of the rib 26, and the other side Is formed so that a gap 27 is formed. As a result, unlike the other portions of the corner 21d, the rib 26 is easily deformed independently. Therefore, the impact energy from the corner portion Pc of the panel Pa acting on the protection member 30 is deformed (compressed). It can be absorbed by deformation or bending). As a result, even when an impact load is applied to the corner portion Pc of the panel Pa of the packaged object P in a state where the packaged material P is packed with the packing material 1, it is directed to the corner portion 21d of the container body 20. The impact load can be reduced.

  Moreover, in this embodiment, the 1st fitting recessed part 25a and the 2nd fitting recessed part 25b which comprise the fitting recessed part 25 are extended in a different direction (direction orthogonal), and the 1st of the protection member 30 is added to these.
