The present invention relates to a packing device used for packing products. Background art

In the conventional packing apparatus, for example, when the object to be packed is an air conditioner, the object to be packed B supported at both ends by a cushioning material A formed in a tray shape as shown in FIG. And tied together with fastening band D to complete packing.

However, the above-described conventional configuration is a structure in which only both ends of the packaged object are supported by the cushioning material, and the center of the packaged object is not supported. Therefore, in the conventional configuration, the packaged product itself is damaged due to the deflection of the packaged product when a drop impact is applied, so the cushioning material shape must be changed or the packaged product must be protected from damage. It was necessary to add partial cushioning. In addition, in the conventional configuration, the cylindrical outer box holds the storage strength, and the cushioning material holds the buffer protection function to protect the packaged object from impact. In many cases, the number of man-hours required for packing work has increased, which has increased costs.

In addition, in the conventional configuration, when unpacking and repacking work, when taking out the package from the inside of the packing device, one side of the opening of the cylindrical outer box is placed on the floor, and the other side is opened. Had to extract the cushioning material and outer box from the container, and then remove the items to be packed. Therefore, workability at the installation site was poor. In addition, the packaged material immediately after the cushioning material and the outer box were taken out was fixed only by the cushioning material on one side, so there was a drawback that the packaged material was accidentally turned over and damaged.

In addition, when handling the packing device, the operator places his finger on the handhole shape provided on the side of the cushioning material. Was being carried. However, the size of the hand holes could not be large enough to affect the storage strength during product storage. Due to small handholes, handling was poor. The present invention is intended to solve such a conventional problem, and is excellent in workability and protection at the time of handling a package, having both a protection function and a storage function for an object to be packaged at a low cost and as one component of a packing apparatus. And a packaging device. Disclosure of the invention

There are surfaces 3—b and 3—c that support Surface 3—a and surface 3—b are separated by crease 4, and surface 3—b and 3—c are separated by crease 5 I have.

In addition, glue margins (lower overlapping portions) 6 and 7 are provided for adhesive bonding with cardboard 1. The glue allowance 6 is located between the face 3-a and the crease 8. The glue allowance 7 is located at the boundary between the surface 3-c and the crease 9. In addition, a glue allowance (upper overlapping part)〗 0 is provided opposite to the glue allowance 6, and the glue allowance 10 is located at the boundary between the surface 3-a and the folding line 11.

FIG. 2 is a diagram showing a packing apparatus in which the members shown in FIGS. 1A and 1B of the present embodiment are bonded and integrated. Cardboard 3 consisting of five sides with folds and a thick paper 3 adhesively bonded by glue allowances 6 and 7 provided on cardboard 3 with folds and cuts at both ends of sides 1 — a and 1-b Things. As a result, the packing apparatus of the present embodiment becomes a single unfolded sheet.

At the time of packing, as shown in Fig. 3A, the thick paper 3 adhesively bonded to both ends of the five-faced thick paper 1 with the folds is bent upright from the folds 8 and 9. The object 2 to be packed is inserted between the upright cardboards 3, and both sides of the object 2 are supported by the surface 3-a of the cardboard 3.

Next, as shown in Fig. 3B, the side 1-b provided on the cardboard 1 is bent along the crease to cover the top and bottom of the package 2. At this time, the sides 3-b and 3-c of the cardboard 3 are folded along the creases 4 and 9 and the crease 5 with the cut. As shown in FIG. 5, the surfaces 3-b and 3-c are adjacent to each other and form a buffer thickness for supporting and fixing the top and bottom of the packaged object 2.
