Is a perspective view of the embodiment in the case of a sealed letter, and FIG. 7 is a development view in the case where the container body can be developed.

The physical distribution packaging container of this embodiment is summarized as follows.
It is composed of two parts, a packing container body 1 and a cushioning air bag 2. The packaging container body 1 is an ordinary cardboard box,
An outer container such as a wooden box or a wooden frame, which is the type of the object 3 to be transported,
Various types are selected and used according to size, shape, form, and the like. Here, a cube-shaped cardboard box is used. An air inlet port lead-out portion 5 for leading out an air inlet port 4 for injecting air into the buffer air bag 2 is formed in a part of the packaging container body 1.

The buffer air bag 2 is a bag body formed of a resin sheet, and is provided with an air inlet 4 in a part thereof so that the amount of internal air can be adjusted. A check valve 4a is provided. The cushioning air bag 2 is a bag body 2a to be arranged on the side inner peripheral surface of the packaging container body 1.
And a bag body 2b arranged on the upper inner surface and a bag body 2c arranged on the lower inner surface, which are integrally fixed to the respective surfaces. That is, the cushioning air bag 2 (2
a side sheet 6 forming a, 2b, 2c) is fixed to the inner surface of the main body 1 of the container, and by injecting air into the inside, the sheet 7 side of the object to be transported expands toward the center of the container 1 to be transported. The object 3 is configured to be pressed and held in six directions. Further, the buffer air bag 2 has an air inlet 4, and the air inlet 4 is disposed in the air inlet outlet portion 5 of the packaging container body 1 so that the buffer air bag 2 is provided from the outside of the packaging container body 1. It is designed to be able to inject air.

Here, as the resin sheet forming the cushioning air bag 2, for example, a multi-layer film obtained by laminating or bonding a low density polyethylene resin, an ethylene-vinyl alcohol copolymer resin, and a polyamide resin with an adhesive is used. I am using. This is because the multilayer film of this structure eliminates the deterioration of the gas barrier property due to the hygroscopicity, which is a difficulty of the ethylene-vinyl alcohol copolymer resin, by the low-density polyethylene resin having strong hydrophobicity and the strength of the low-density polyethylene resin. Is reinforced with a polyamide resin, has excellent film properties in all aspects such as gas barrier properties, chemical resistance, and physical strength, and is preferable for forming a bag. As this resin sheet, different kinds of multi-layer film, vinyl chloride,
Alternatively, a polyethylene sheet is used.

Further, the transportation object side sheet 7 forming the transportation object 3 side of the cushioning air bag 2 is formed by the air inclusion sheet 8 made of the different type multi-layered film having the above-mentioned construction. The air-encapsulating sheet 8 has a projection film made of a different type of multi-layer film airtightly integrated with an adhesive on the upper surface side of the flat film made of the different type of multi-layer film (usually so that the low density polyethylene resin faces each other). A large number of air-encapsulation projections 9 are formed on the inner surface of the projection. Further, in the case of this configuration, the impact resistance can be further reduced.

In the above-mentioned physical distribution packaging container of the present embodiment, the buffer air bag 2 is attached to or formed on the inner peripheral portion of the container body 1, and the transportation object 3 is stored so as to be covered with the buffer air bag 2. After that, when air is injected into the buffering air bag 2 through the air inlet 4 provided in the container body 1 to inflate the buffering air bag 2, the buffering air bag 2 conforms to the outer shape of the transport object 3. It is deformed to form a void portion 1 between the container body 1 and the object 3 to be transported.
It can be fixed and held by setting 0 to the filled state and applying pressure to the object 3 to be transported from the inner peripheral wall of the container body 1. Here, since the check valve 4a is provided in the air inlet 4, the injected air is not discharged without operating the check valve 4a. The internal pressure does not drop, and the object to be transported can be fixed and held in a stable state at all times.

By adjusting the amount of air injected into the buffer bladder 2 and adjusting the internal pressure of the buffer bladder 2,
It is possible to stabilize and hold the transportation object 3 of various types, shapes, and forms in the container. Here, in the case where the transport object 3 is a heavy object such as an electric product or has a form having a sharp protrusion (particularly when formed on the bottom surface), the buffer air bag 2 may be damaged. Because of this, this transportation target 3
It is preferable to use the plate body 11 having rigidity between the cushioning air bag 2 and the cushioning air bag 2 (see FIG. 4).
Here, a refrigerant may be used as the air. In the case of this structure, it acts so that it can be used as a storage and transportation container for fresh food. Further, a liquid can be used instead of the gas body.

Therefore, in the case of the physical distribution packaging container of the above-mentioned embodiment, since the transportation target object 3 forms the buffer air layer in the packaging container body 1 by the buffer air bag 2, the transportation target object of all kinds. However, it is held in a stable state inside the container and is damaged by vibration or falling during transportation.
You can avoid damage.

It should be noted that the present invention is not limited to the above-described embodiments, but includes configurations that can be modified and implemented within the scope of the present invention. Incidentally, it goes without saying that the configuration shown in FIGS. 5 to 7 may be adopted. The configuration shown in FIG. 5 is different from the above-described embodiment in that the cushioning air bag 2 in which the air inclusion sheet is not arranged on the side of the object to be transported is used. Here, the cushioning air bag 2 may have a form in which a sheet body such as a canvas or a non-woven fabric is polymerized in order to impart strength to the inner surface or the outer surface of the bag (this configuration can also be applied to the above-mentioned embodiments. ).

The configuration shown in FIG. 6 is embodied as an item delivery envelope 12 as a physical distribution packaging container.
That is, the cushioning air bag 2 is arranged as the lining material of the envelope 12, and the envelope 12 normally takes the form of a quadruple bag, and the air inlet 4 has the outer tongue piece. It is configured to be hermetically sealed by the portion 13. And
This structure has a further cushioning effect as compared with a conventional envelope containing a packaging material such as an air-encapsulating sheet, and can be effectively used as a bag for delivering small items such as machine parts and electronic device parts.

Further, the configuration shown in FIG. 7 is embodied as a corrugated cardboard box 14 which can be developed as a physical distribution packaging container. That is, the cushioning air bag 2 is integrally formed in advance on each surface 14a (usually 6 surfaces) forming the cardboard box 14, and the cardboard box 14 is folded at the same time as the cardboard box 14 is folded. The cushioning air bag 2 is attached so that an air layer can be obtained. Here, the cushioning air bag 2 is not formed separately corresponding to each surface of the box 14, but is usually formed as one bag body, and is configured to be able to inject air from one air injection port 4. ing. The partition may be partially formed as necessary, or a plurality of air bags may be formed and connected to each other by a pipe or the like.

[0022]

As is apparent from the above description, according to the distribution packaging container of the present invention, since the buffer air bag capable of adjusting the air injection amount is attached or formed on the inner periphery of the container body, the container is formed. The void portion formed between the main body and the object to be transported has an effect that it can be easily filled and stable and held regardless of the type, shape, and form of the object to be transported.

Therefore, according to the present invention, it is possible to provide a physical distribution packaging container which is easy to handle, can buffer-protect a transportation object which is easily damaged or damaged by an impact during transportation, and can reduce the generation of waste.
