Description

  The present invention relates to a panel packaging body for packaging a panel for a display device or a panel such as a glass substrate which is a component of the display device panel, and more specifically, a packaging box comprising a box and a lid. It is related with the package for panels which comprises two or more sets.

  Conventionally, as a panel packing body for packing a panel such as a liquid crystal panel and a panel for a display device represented by an electroluminescence panel and a glass substrate which is one part of the display device panel, there are various configurations. Are known. As one of them, using a packing box composed of a box having an opening on the upper surface and a lid for closing the opening, in a state where panels and buffer sheets are alternately stacked on the housing of the box There are some which are configured to be accommodated (for example, see Japanese Patent Application Laid-Open No. 2007-84124 (Patent Document 1), Japanese Patent Application Laid-Open No. 2007-314236 (Patent Document 2), Japanese Patent Application Laid-Open No. 2008-239210 (Patent Document 3), etc.) ).

  The packaging box composed of the box and the lid is generally formed of a resin foam, and is advantageous in terms of weight reduction and impact resistance, and has an advantage that it can be manufactured at a relatively low cost. In addition, the box and the lid can be fitted to each other, so that the sealability of the accommodating portion in which the panel is accommodated can be kept high. There is an advantage that it is possible to prevent such foreign matters from adhering. Thus, various advantages can be obtained by using a packaging body for a panel that uses a packaging box composed of a box and a lid.

  However, in the case of the panel packaging body configured using the packaging box composed of the box body and the lid described above, the stacked packaging boxes become bulky in the height direction during transportation or storage. There is. This is because the lid is individually attached to the box, so that an extra volume is generated by the thickness of the lid. This problem becomes particularly prominent when the panels are configured to be accommodated in the packaging box in a divided manner, resulting in a problem that the number of panels accommodated per predetermined volume is reduced, and transportation costs and storage costs are increased.

  On the other hand, in recent years, various display devices have been greatly increased in size, and accordingly, a large-sized panel such as a display device panel and a glass substrate which is a component of the display device panel is distributed. Is starting to do. When such a large panel is accommodated in the packaging box, the panel needs to be accommodated in the packaging box in order to facilitate handling of the packaging box in a state where the panel is packaged. That is, when a large number of panels are packed in a packing box, the weight of the entire packing box is greatly increased, and it is virtually impossible to manually move or transfer the packing box.

  Usually, equipment such as a forklift or a dedicated transfer device is often used for moving or transferring the packaging box in a state where the panel is packed. However, depending on the location, the equipment is not necessarily complete, and even if the equipment is fully equipped, it may be sufficiently assumed that manual movement or transfer is required. Therefore, in the panel packaging body, it is necessary not only to support movement and transfer using dedicated equipment but also to support manual movement and transfer.

  In consideration of the above, the box is not individually provided with a lid, but a heavy box-like structure that allows the boxes to be directly stacked is adopted, and the lid is only attached to the box located at the uppermost stage. It is conceivable to have a configuration for mounting. If comprised in this way, the thickness which a cover body occupies in a height direction can be reduced significantly, and it suppresses that the packaging body for panels is bulky in a height direction, accommodating a panel in a box. be able to. However, in the case of a panel packaging body adopting such a heavy box-like configuration, the following problems arise separately.

  1stly, since it is the structure which does not provide a cover body in a box individually, when storing a box body without laminating | stacking, the number of cover bodies is insufficient, and the accommodating part of a box body will be exposed. The foreign matter may adhere to the panel. To solve this problem, prepare the necessary number of lids separately in advance and transport them together with the packing body packed with the panel, or prepare a plurality of lids in advance at the delivery location, etc. Although this can be solved by taking measures, it is necessary to transport or store only the lid, and in reality, complicated management is required.

  Second, in order to move or transfer the packing box using a forklift or a dedicated transfer device, a transfer groove for inserting a support arm (fork) is provided on the side of the lower surface of the box. However, when the box is provided with the groove, when the boxes are stacked in a heavy box shape, the housing part communicates directly with the outside through the groove. As a result, there arises a problem that foreign matter such as dust or dust adheres to the panel during transportation or storage. More specifically, the transfer groove is usually provided on the lower surface of the box so as to reach a pair of opposite side surfaces, but when the boxes are stacked in a heavy box shape, When the housing portion of the box body and the groove portion of the box body located in the upper stage of the box body face each other directly, the end portions of the groove portion (that is, a pair of opposed box bodies stacked in a heavy box shape) The edge part of the groove part located on the side surface is exposed to the outside, and a problem arises in that foreign matter enters the housing part of the lower box from the exposed edge part of the groove part.

  Thus, as a structure of the panel packaging body, it is not sufficient to simply stack the boxes in a heavy box shape, and further improvement is necessary.

  Therefore, the present invention has been made to solve the above-described problems, and can maintain the hermeticity of the accommodating portion in which the panel is accommodated during transportation or storage, and a dedicated facility is used. An object of the present invention is to provide a panel packaging body that not only supports movement and transfer, but also supports manual movement and transfer, and does not become bulky in the height direction when stacked.

  In order to solve the above-described problem, the present inventors do not provide a groove for transfer on the lower surface of the box of the packaging box, but a hollow shape extending inward from the side surface to the bottom plate of the packaging box. The idea is to provide a hole so that the lower upper surface opening is completely closed by the lower surface of the upper box even when the boxes are stacked in a heavy box shape. However, when the configuration is adopted, it is necessary to form the thickness of the bottom plate portion of the box to a considerable extent, and as a result, there arises a problem that the thickness in the height direction becomes bulky by the thick bottom plate portion. End up. In addition, when this configuration is adopted, it is also necessary to prepare a necessary number of lids in advance and transport them together with the package in which the panel is packed. Therefore, it is necessary to take measures such as preparing a plurality of items in advance, and complicated management as described above is required.

  Therefore, the present inventors prepared in advance the number of lids corresponding to the number of boxes, and when the boxes are not used stacked in a heavy box shape, attach them individually to the box. When the container located inside each box can be sealed, and the boxes are stacked and used in a heavy box shape, a lid is attached to the upper surface of the box located at the uppermost stage, and the stacked boxes It was conceived that all of the above problems could be solved by attaching an excess lid remaining on the opposite side surfaces of the body and closing the end of the groove located on the side surface with the attached lid.
