DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning packing material, and more particularly to a packing cushioning material used for packing an article to be packed such as an electronic device.

[0002]

2. Description of the Related Art Conventionally, foamed synthetic resin materials such as foamed polystyrene and foamed polyurethane have been widely used as a cushioning material of this kind. However, these synthetic resin foam materials have a large volume and are therefore transported and used during storage. There is a problem that the space is taken up at the time of later disposal and the cost increases. In addition, there is a concern that disposal problems after use may cause pollution problems.

There is a method of using a so-called air bag in which an air bag made of a synthetic resin is filled with air as a cushioning material for solving such a problem. For example, Japanese Utility Model 4-100
No. 470 is disclosed. FIG. 6 is a vertical sectional view showing a state of packing in this conventional example. In FIG. 6, a buffer bag, which is a non-breathable hermetic bag, is placed so as to wrap the baggage 63 in the carrying case 62 of the cardboard box.
The bag is inflated by feeding air from the air supply port 64 with a non-return action provided in 1 and the bag 63 is fixed in the case.

FIG. 7 shows another example of the prior art.
(A) in this conventional example is a plan view in which a cushioning material for packing is developed, and (b)
FIG. 3 is a perspective view showing a state in which the article to be packaged is packed with the packing cushioning material. In FIG. 7A, the packing cushioning material 7 is used.
Reference numeral 1 denotes five connected or superposed two films or sheets made of a synthetic resin, which are formed in a bag shape and are covered corresponding to the front surface, upper and lower surfaces, and left and right side surfaces of the packaged object 72. Air bags 73, 74, 75, 76, 77.
The air bags 74 and 76 are divided into two small compartments, and the air bags 73 and 75 are divided into three small compartments.
In addition, all the compartments are illustrated as communicating with each other by a flow channel 71a formed by a non-adhesive portion of two films. The air bag 73 is provided with an air inlet 78 at one location. By injecting air from the air inlet 78, five air bags 73, 74, and 7 are provided.
5, 76, 77 are configured to expand.

In FIG. 7 (b), the cushioning material 7 for packing is used.
In order to pack the article to be packed 72 in the first step, each of the five air bags 73, 74, 75, 76, 77 is inflated from the air inlet 8, and the five air bags 73, 74, 75 are inflated. , 7
6, 77 cover the front, upper and lower surfaces, and left and right side surfaces of the packaged object 72. Then, it is put in the outer box in this state.

[0006]

As described above, the cushioning material for packing an air-filled air bag in the conventional example is formed of a thin film sheet or the like, so that the cushioning material itself is light, and the air is released. It can be stored, transported, or disposed after use, so that there is an advantage that the space is saved, the cost is low, and there is almost no pollution.

However, in the former in the conventional example,
Since the air bags are separated one by one, there is a problem that it takes time and labor when filling or discarding air.

In the latter, a plurality of air bladders are communicated according to the shape of the article to be packaged, so there is no problem as in the former, but when the shape of the article to be packaged changes, the configuration of the air bladder also increases. It is necessary to change it, and there is a problem that the air bag is dedicated and cannot be standardized depending on the shape of the article to be packaged.

[0012] Alternatively, a plurality of airbags communicating in a straight line are provided, and a connection portion of each of the airbags or a predetermined airbag is detachable, and a check valve for flowing air in one direction is provided. The air bag at the uppermost stream in the flow direction has an air supply port and the air bag at the most downstream in the air flow direction has an air outlet, and each air bag is filled with air from the air supply port. In addition, the air in each air bag can be exhausted from the exhaust port.

[0013] Alternatively, a plurality of airbags may be radially communicated around at least one airbag so as to wrap the packaged object, and the connection portion of each airbag or a predetermined airbag can be separated and air can be separated. A check valve for flowing in one direction is provided, and an air supply port portion of the air bag at the center of the radially communicated air bag and an exhaust port portion at each end of the air bag radially communicated with the air bag are provided. Each air bag is filled with air from an air supply port, and air is discharged from each air port to each air bag.

Further, the airbag provided from the air supply port and the airbag provided with the exhaust port may be color-coded mutually.
