- the air-cushioning material is characterized in that two sheets of synthetic resin films prepared in accordance with a dimension and shape of a product to be packaged are stuck to each other, inner edge parts thereof forming an end part of an outer frame, inner edge parts formed by dividing longitudinal intermediate parts thereof into multiple parts between the inner edge parts, and divided edge parts formed by similarly dividing vertical intermediate parts thereof into multiple parts are thermally fused each other, and at least one air flow port is provided to the inner edge parts and the divided edge parts to form a frame having a plurality of air chambers communicating with each other.
- the air-cushioning material is further characterized in that at least one of the air chambers is provided with an air filler port with a check valve function, air is filled through the air filler port into the air chambers to inflate an entirety of the air chambers, and thereby the inside thereof is pressed against the product and the outside thereof is pressed against an inner wall of the carrying container.
- the invention is characterized in that, in the foregoing frame air-cushioning material, air chambers at a bottom end are folded inside, notches are disposed so that an angle of 90° may be formed at a part where the inner edge part and the divided edge part intersect, notch edge parts thereof are thermally fused to form a bottom part made of a plurality of air chambers; and parts where the inner edge parts of the air chambers at a top end and the divided edge parts interest each other are, so as to be folded inside, thermally fused partially on a diagonal line to form a top cap part made of a plurality of air chambers.
- the invention is characterized in that, in the frame air-cushioning material, the air chambers at the top and bottom ends are folded inside, notches are disposed so that an angle of 90° may be formed at parts where the respective inner edge parts and divided edge parts intersect, and notch edge parts of the notches are thermally fused to form a bottom part and a top cap part same in shape and having a plurality of air chambers.
- the air-cushioning material according to the invention is characterized in that, in the frame air-cushioning material, the air chambers at the top and bottom ends are folded inside, parts where the respective inner edge parts and divided edge parts intersect, so as to be folded inside, are thermally fused partially on a diagonal line to form a bottom part and a top cap part having a same shape and a plurality of air chambers.
- the air-cushioning material according to the invention is characterized in that, in the frame air-cushioning material, in place of an air filler port provided to at least one of the air chambers and having a function of check valve, after air is filled in the air chambers, the air-filler port is thermally fused to seal.
- the air-cushioning material according to the invention is characterized in that, in the frame air-cushioning material, an antistatic agent is mingled in a synthetic resin film constituting a raw material.
- FIG. 1 is a plan view showing a state before forming a frame of a synthetic resin film that forms an outer frame of a frame air-cushioning material according to an example of the invention.
- FIG. 2 is a plan view showing a state before forming a frame (corresponding to FIG. 1 ) in another example.
- FIG. 3 is an enlarged perspective view schematically showing an inflated state of a single air chamber in another example.
- FIG. 4 is a plan view showing a state before forming a frame (corresponding to FIG. 1 ) in still another example.
- FIG. 5 is a plan view showing a state before forming a frame (corresponding to FIG. 1 ) in still further another example.
- FIG. 6 is an entire perspective view schematically showing a state before use of a frame air-cushioning material formed according to one example of the invention.
- a packaging frame air-cushioning material will be exemplified.
- the frame air-cushioning material according to the invention can be preferably applied not only to packaging rectangular ones but also to packaging polygonal articles having a specified thickness.
- a frame air-cushioning material is formed by stacking, as shown in FIG. 1 , a first frame film 1 and a second frame film 2 both made of a synthetic resin, thermally fusing inner edge parts 5 and inner edge parts 6 that are divided longitudinally into four, and forming a belt-like synthetic resin film having four air chambers having a length of 1225 mm and a width of 40 mm.
- the inner edge parts 5 and the inner edge parts 6 are provided with a width of 5 mm as a fusing margin.
- the material is partitioned into squares having a side of 300 mm, and divided edge parts 13 are thermally fused to form a belt-like synthetic resin film made of substantially 16 rectangular air chambers 7 .
- at least one non-fused part is provided to the inner edge parts 6 and the divided edge parts 13 to form an air flow port 8 , and through the air flow ports 8 the respective air chambers 7 are integrally communicated.
- At least one of the air chambers 7 is provided with an air filler port 3 and the air filler port 3 is provided with a check valve 4 .
- the respective chambers Owing to air supplied from the air filler port 3 , the respective chambers have a desired uniform air pressure (3.5 Kpa/cm 2 in the example) to be inflated.
- the air filler port 3 may be thermally fused to be sealed after air is filled in.
- Notches 12 are formed so that when four air chambers 7 positioned at the bottom end of the belt-like synthetic resin film made of 16 rectangular air chambers 7 in the example are bent inside, the four air chambers may form a substantial right-angle of 90°, notch edge parts 14 of the notches 12 are thermally fused to form a bottom part 9 made of four air chambers, and thereby as shown in FIG. 6 a square frame having the bottom part 9 is completed.
- a bottom surface of a precision electric component packaged with the cushioning effect of the bottom part 9 has an increase in the friction resistance owing to a surface contact, the cushioning effect owing to air and protection owing to the frame shape, and so can be secure from fears such as collapse of cargo or slippage.
- FIG. 1 In another example according to the invention, as shown in FIG.
- a top cap part 10 ′ is processed similarly to the bottom part 9 , and thereby an article to be packaged is packaged as if surrounding it by attaching by winding from a periphery (side face) and above and down. Accordingly, more stable cushioning effect can be expected.
- a top cap part 10 having folding parts 11 and four air chambers is formed, and thereby an upper (or surface) constituent part of a precision electric component to be packaged is protected by air chambers in square. Accordingly, even when the precision electric components are stacked to be housed in a housing container, contacts between the components or contacts between the components and the housing container owing to the collapse of cargo can be prevented in advance from occurring. Furthermore, when a notch is disposed in the center of the folding part 11 , the top cap part 10 is allowed to open outside; accordingly, the components can be readily set and taken out.
- an A-B part of the frame is thermally fused and a C-D part is simply folded, the frame becomes capable of coping with arbitrarily-shaped articles to be packaged.
- An air filler port 3 ′ in the example is not provided with a check valve, but after air is filled in, is sealed by thermal fusion to form a seal 4 ′ as mentioned above.
- Such a process can be selectively applied also to other examples.
- four air chambers located at a bottom end may form a frame in a same shape with respect to the top cap part 10 and the bottom part 9 ′ as shown in FIG. 5 , as a bottom part 9 ′ of a structure having a folding part 11 ′ so that four corners thereof can be conveniently folded inside similarly to the top cap part 10 according to the example shown in FIG. 1 .
- the cushioning member according to the invention can package an article to be packaged by not only vertically sandwiching but also clasping sideward.
- the frames in the respective examples are constituted so that in accordance with a dimension and a shape of an article to be packaged the number of steps of the air chambers and a length of partition thereof are controlled.
- the air chambers can be disposed connecting in a vertical direction as well, and when such a structure is taken, the frame can be used as a cushioning material of a polygonal article to be packaged, finally a disc-like article to be packaged.
- a frame air-cushioning material is formed with one where in a synthetic resin film that is a frame-forming raw material, specifically PE/PA/PE, PE/PETAL or deposition/PE, an antistatic agent is previously mixed.
- an antistatic agent is previously mixed.
- the number of air chambers on a side surface is further increased to be capable of preferably packaging a thicker product or the like. Furthermore, by applying lamination to a crossed portion, the wear resistance and the impact resistance can be improved and thereby the safety can be further secured.
- a shape of the frame air-cushioning material is formed into a rectangle in accordance with a shape of a corresponding precision electric component.
- the frame air-cushioning material according to the invention having advantages such as shown below, is very high in the industrial value thereof. That is, the frame air-cushioning material according to the invention, only by filling in air, comes to completion in a inner packaging state; accordingly a packaging operation becomes very convenient.
- a shape of the cushioning material is formed in accordance with an external shape of a product to be packaged; accordingly, when, in particular, rectangular products or the like are packaged, there is no fear of causing slippage from left to right and up and down with an external packaging container, and, together with the cushioning effect owing to air, even in storage or transport of precision instruments such as medical instruments and semiconductor products, excellent safety can be secured.
- the frame air-cushioning material according to the invention when a synthetic resin film that is a raw material thereof is mixed with an antistatic agent and used, can prevent in advance the electrification of static electricity which is most hated in the precision electric components and medical instruments from occurring, and thereby the malfunction of a machine caused thereby and adhesion of dust can be effectively avoided.
- materials to be used are reduced to the limit and the cushioning material before use, being a thin sheet, largely contributes to reduction of a storage space and transportation cost and to energy saving.
