BACKGROUND OF THE INVENTION
  The present invention relates to a cardboard or cardboard packaging device having a packaging object holding or protecting means for holding or protecting a packaging object at a predetermined position, and an assembling method thereof.
  As the above-mentioned packaged items, in addition to the articles themselves provided for the purpose, for example, difficult-to-stand containers (or flexible containers, the same applies hereinafter), that is, deformed by the contents or the same form as the contents A container made of a material to be taken is filled with the contents, for example, a sealing material, various paints, etc., which are filled with a building fluid material such as powder, granule, liquid or viscous material used for construction.
[0002]
[Prior art]
  Conventionally, it is known to use a packing or a holding or protective frame adapted to the packaged object in order to hold or protect the packaged object at a predetermined position of the packaging body.
[0003]
[Problems to be solved by the invention]
  These packings and holding or protective frames have the inconvenience that must be prepared separately from the packaging body itself, and in addition, packing is loaded in the gap around the packaged items in the packaging body, As for the holding or protecting frame, there is a problem that it has to be accommodated in the packaging device in a state in which the object to be packaged is loaded or fitted.
[0004]
  The object of the present invention is to integrate holding or protecting means corresponding to the packing, holding or protecting frame, that is, to-be-packaged holding or protecting means for holding or protecting the to-be-packaged object in a predetermined position, integrally with the packaging body. In order to eliminate the inconvenience and inconvenience as described above, the packing, holding, or protective frame is manufactured and prepared separately from the packaging body. It is to reduce the cost required for loading, the cost required for the loading or fitting work, the manpower, and the like.
[0005]
  In addition, the above difficult-to-be-sustained containers, that is, containers made of materials that are deformed by the contents or take the same form as the contents are literally difficult to stand by themselves, compared to self-supporting containers made of metal or hard synthetic resin. In addition to being inconvenient for filling or taking out the contents, it is also inconvenient for packing, shipping and storage in the state in which the contents are filled.
[0006]
  However, the above-mentioned self-supporting container is generally expensive and must be collected after being used after being crushed or left in a bulky state. Despite the disadvantage of generating harmful substances such as dioxins when disposed of or recycled, difficult-to-stand containers are relatively inexpensive and can be collected in a non-bulky state such as being easily folded after use. It is advantageous as a container because it hardly generates harmful substances such as dioxin when it is incinerated or recycled.
[0007]
  Another object of the present invention is to make use of the above-mentioned advantages of a difficult-to-support container, while eliminating the inconvenience of filling or taking out the material, packing in the packed state, shipping transportation, and inconvenience of storage. Is to provide.
[0008]
  Still another object of the present invention is that it is possible to automatically assemble and reduce the manufacturing cost, and yet is made of corrugated cardboard and cardboard that can be subjected to pollution-free processing after use, but has a higher external force, particularly compressive load resistance, compared to the conventional one. An object of the present invention is to provide a packaging device that can be stacked several tens of levels depending on the case, even if the packaged items are in a weighted state.
