Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a packaging device used for packaging objects such as air conditioners. In addition, a bottom plate a is provided in which a buffering material is attached to a tray-shaped outer box to support the packaged items, and a top plate is provided in which a buffering material is attached to the tray-shaped outer box in the same way as the bottom plate a. Supports c1, c2, c3, which are inserted into each corner of the bottom plate a and the top plate and connect the bottom plate and the top plate.
c4 is provided, the object to be packed d is stored in the space between the bottom plate and the top plate connected by the supports C1, c2, c3, and c4, and the bottom plate and the top plate are tied together with the band e to complete the packaging. Problems to be Solved by the Invention However, with this type of packaging device, it is necessary to provide supports at each corner to protect the items to be packed from the load of stacking during storage, and the supports also bear the unbalanced load during stacking. Taking into consideration factors such as strength and strength variations, we use sturdy pillars with thick plates to prevent them from bending due to easy force.In addition, because the four pillars are fixed individually, the pillars are vulnerable to external forces from the horizontal direction. There is a risk of quality deterioration during storage if the support is tilted.Furthermore, this support is easily handled by hand during cargo handling, and bending strength is also required to withstand being pulled sideways. In addition, when using a packaging device using pillars for large, tall products or heavy items, it is difficult to make pillars with sufficient strength to reliably protect the items to be packed. There are drawbacks such as quality deterioration during cargo handling and high material costs.Therefore, the present invention (which eliminates all of these conventional drawbacks and uses inexpensive materials for storage and handling) The present invention provides a packaging device that can be applied to large and heavy items and improves the stability and quality of the products. Means for solving the four problems Invention C & Two fold lines form a U-shape. The side pillars were fixed tightly along the fold line so that they were located at the inside corner of the U-shape with the paperboard in a U-shape. Also provided
Furthermore, a bottom plate and a top plate with a buffer inserted inside both ends of the tray-shaped outer box are installed.Both the bottom plate and the top plate have the outer surface of the buffer inserted inside and the width of the outer box. Along with forming a groove into which the above-mentioned side pillar can be inserted! ζ An L-shaped cut portion is provided at each corner of the outer box of the buffering material to be inserted.The present invention has the structure described above, and the support is inserted into the inside of the U-shaped paperboard. Fixed side columns increase strength against stacking loads during storage, improving quality during storage.Horizontal columns improve protection from strong storms and external forces, improving quality during storage and handling. Embodiment: An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In FIG. 1, 1 is corrugated paper. It is a side pillar that is formed in a U-shape and protects the packaged items from the stacking load during storage. Two folding lines 3 are provided for folding into a shape. Furthermore, fix the support 4 with adhesive or the like so that it is aligned with the fold line 3 on the inside of these two fold lines 3. The position is slightly shifted from the fold line 3 so that it is the inside corner of the bent corner.In Fig. 1, 5 is the bottom K that supports the object to be packed.6 is also the object to be packed. As shown in detail in FIG. 3, the base plate 2 of the side column 1 and the support column 4 are inserted into the bottom plate 5 and the top plate 6 when the outer package is formed into a tray shape from corrugated paper or the like. L for easy insertion
Even though the cut portion 9 in the shape of a letter is provided at the corner, when inserting the buffer material 8 into the outer box 7, the groove tl for easily inserting the mount 2 of the side column l into the bottom plate 5 also creates a buffer. Material 8
Even if it is formed between the side surface 8a of the outer box 7 and the width surface 7a of the outer box 7,
When packing, the item to be packed is inserted into the cushioning material 8 of the bottom plate 6, and the mount 2 and pillar 4 of the side column 1 are inserted into the groove t1 of the bottom plate 6 and the cut portion 9 of the cushioning material 8. 1 into the bottom plate 5 facing each other, then top plate 6 from above.
In the same way as the bottom plate 5, the mount 2 of the side column l and the column 4 are attached to the top plate 6.
The package is completed by inserting the item into the groove t1 and the cut portion 9 of the top plate 6 and the buffer material 8 of the top plate 6, and finally binding the bottom plate and the top plate with the band 10. By making the pillars 4 installed on the side pillars 1 in close contact with the mount 2, the two pillars 4 are always integrated and exhibit strength against horizontal external forces such as tilting and shifting. Therefore, vertical stability is increased, and strength loss due to variations in stacking loads during storage is prevented, and strength and stability during storage are also improved.Furthermore, workers do not have to hold the support while handling cargo, making it easier to handle cargo. TF also prevents accidents.
By providing side pillars, it is possible to improve the workability of cargo handling by providing holes for the handles like in conventional cardboard boxes, and it is also possible to improve the design of the packaging box. This packaging device has various advantages, such as improved safety and increased strength against stacking loads, making it possible to reduce the safety factor relative to the strength of the support itself, and reducing the manufacturing cost of the support.

Effects of the Invention As is clear from the above embodiments, the packaging device of the present invention, in which the bottom plate and the top plate are connected by side pillars with pillars fixed to the inside of the C-shaped paperboard, increases the strength against loads during storage. It is a packaging device that improves storage stability, improves safety and workability during cargo handling, and improves the overall quality of transportation.It is also a packaging device that can produce cost benefits. Large size and
It can also be applied as simple and inexpensive packaging for heavy items.
