Description

[Detailed description of the invention] Industrial application field The present invention is a packaging method for packaging objects such as equipment to protect them from damage to their surfaces when packaging and transporting them. This is a reinforcing material for packaging used in the corners of boxes.

BACKGROUND TECHNOLOGY Conventionally, the above-mentioned reinforcing material for packaging has been made of an angular hollow material such as paperboard that does not have a reinforcing material such as wood inside, or an angular hollow material such as paperboard that does not have a reinforcing material inside the hollow material. In some cases, a reinforcing material such as wood to be stored in a container and a molded polystyrene foam material to fill the space between the two were prepared separately, and these were assembled together.

Problems that the invention aims to solve Regarding the conventional packaging reinforcing materials mentioned above, the former is simply an angular hollow material such as paperboard, so when used in the corners of a packaging box, it lacks strength due to the internal hollowness. In the latter case, a reinforcing material such as wood is housed inside an angular hollow material such as paperboard, and a Styrofoam material with no adhesive is inserted between the hollow material and the reinforcing material to create an assembly type. Because it is a thing,
These parts are not adhesively fixed together and tend to come apart, and furthermore, a special mold is required for molding the styrofoam material, making it economically extremely expensive.

Means for Solving the Problems The present invention eliminates both of the above drawbacks, stores reinforcing material such as wood inside an angular hollow material such as paperboard, and creates an adhesive space between the hollow material and the reinforcing material. The purpose of this is to obtain an angular elongated object by integrally foaming and adhesively fixing it using a strong urethane foam material.

Function Therefore, as shown in Figure 3 A and B, angled long reinforcing members a, a, etc. were inserted vertically into the four corners of the packaging box B that covered the packaged item A, and a lid c was placed. rear,
The reinforcing material can be positioned from the outside of the box by wrapping it with string or PP bands (polypropylene bands), or it can be placed in an angular length along the outside edge of the packaging box B containing the items to be packed, as shown in Figure 4. Shaku reinforcing material a, a
...and then pack the outside of the reinforcing material with string or PP band b.

Embodiment In Fig. 1, reference numeral 1 denotes a long hollow exterior material with an angular cross section made of a hollow paper tube such as paperboard. Inject and foam the foam material liquid 3,
The packaging reinforcing material a is obtained by integrally bonding and fixing the exterior material 2 and the reinforcing material 2.

The manufacturing method is as shown in Fig. 2, by tilting the hollow exterior material 1 into a chevron shape, inserting the reinforcing material 2 into it, and pouring the undiluted solution of the urethane foam material 3 into the space 4 as shown by the arrow. Inject it into the container and seal it.
It is foamed and integrally adhesively fixed.

In other embodiments, as shown in FIG.
The shape is the same, and the reinforcing material 2 such as wood stored inside the reinforcing material 2 is a flat plate (A, 2) or an angular shape (B, C), and its position within the exterior material can be changed as appropriate. As shown, the angle angle α of the exterior material 1 can be made smaller than a right angle.

The exterior material may be paper such as kraft paper, cardboard base paper, building material base paper, paperboard, woven fabrics made of nylon, vinylon, rayon, glass fiber, etc., plastic films such as polyethylene, polypropylene, etc., and the reinforcing material may be, Wood materials such as plywood, particle board, fiber board, plastic materials such as vinyl chloride resin and styrene resin, metal materials such as aluminum, etc. may be used.

Effects of the invention This invention uses a reinforcing material such as wood, which is inserted into an angular hollow exterior material such as paperboard, as a reinforcing material for packaging.
The space is filled with urethane foam material, and the exterior material and reinforcing material are integrally bonded and fixed, so there is no need to assemble them one by one.
This has the effect that the reinforcing material for packaging can be obtained economically and at low cost without the materials falling apart.
