Frame air-cushioning material

Abstract

An inexpensive frame air-cushioning material capable of compactly and stably packaging precision apparatuses formed in rectangular shapes and having specified thicknesses, wherein two sheets of synthetic resin films are stuck to each other, the inner edge parts thereof forming the end part of an outer frame, the inner edge parts formed by dividing the longitudinal intermediate parts thereof into multiple parts between the inner edge parts, and the divided edge parts formed by dividing the vertical intermediate parts thereof into multiple parts are thermally fused to each other and at least one air flow port is provided at the inner edge parts and the divided edge parts to form a frame having a plurality of air chambers communicating with each other. The frame air-cushioning material is characterized in that air is filled in the air chambers through an air filler port provided on at least one of the air chambers to inflate the entire part of the air chambers so that the insides thereof can be pressed against a product and the outsides thereof can be pressed against the inside walls of a carrying container.

1 . A frame air-cushioning material that is interposed between a product to be packaged and an inner wall of a carrying container to protect the product from the external force such as impact, 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 edge 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 dividing vertical intermediate parts thereof into multiple parts are thermally fused to 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; and 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 the inside thereof is pressed against the product and the outside thereof is pressed against an inner wall of the carrying container.  
   
   
       2 . The frame air-cushioning material according to  claim 1 , wherein air chambers at a bottom end of the frame air-cushioning material are folded inside, notches are disposed so that an angle of 90° is formed at a part where the inner edge part and the divided edge part intersect, and notch edge parts of the notches 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 portions interest each other, so as to be folded inside, are thermally fused partially on a diagonal line to form a top cap part made of a plurality of air chambers.  
   
   
       3 . The frame air-cushioning material according to  claim 1 , wherein the air chambers at top and bottom ends of the frame air-cushioning material are folded inside, notches are disposed so that an angle of 90° is 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 having a same shape and a plurality of air chambers.  
   
   
       4 . The frame air-cushioning material according to  claim 1 , wherein 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.  
   
   
       5 . The air-cushioning material according to  claim 1 , wherein the 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.  
   
   
       6 . The air-cushioning material according to  claim 1 , wherein an antistatic agent is mingled in a synthetic resin film constituting a raw material.
