Shockproof packing bag

Abstract

A shockproof packing bag includes an upper and a lower bag body combined together and formed with an accommodating chamber therebetween. The upper and the lower bag body are respectively provided with an inner layer and an outer layer, which have their peripheral edges combined together by thermal fusing to form the upper and the lower bag body. The upper and the lower bag body have their peripheral edges attached with a zipper and are respectively formed with an air chamber between the inner and the outer layer. The upper and the lower bag body have one lateral side thermally fused together to form a compressed side having an air tap fitted therein. After inflated, the packing bag will form plural air bags for wrapping and positioning articles therein, having effect of shock prevention, usable repeatedly and highly effectively for environmental protection.

1 . A shockproof packing bag comprising an upper bag body and a lower bag body combined together, between said upper bag body and said lower bag body formed an accommodating chamber, said upper and said lower bag body respectively provided with an inner layer and an outer layer, said inner layer and said outer layer having their peripheral edges combined together by thermal fusing to form said upper bag body and said lower bag body, said upper and said lower bag body having their peripheral edges attached with a zipper, an air chamber formed between said inner layer and said outer layer, said upper and said lower bag body having one lateral side combined together by thermal fusing to form a compressed side, said compressed side having an air tap fitted therein.  
   
   
       2 . The shockproof packing bag as claimed in  claim 1 , wherein said upper and said lower bag body have their peripheral edges respectively combined with a male zipper member and a female zipper member by thermal fusing.  
   
   
       3 . The shockproof packing bag as claimed in  claim 1 , wherein said inner layer and said outer layer of said upper and said lower bag body are respectively provided with a plurality of compressed points therebetween.  
   
   
       4 . The shockproof packing bag as claimed in  claim 1 , wherein said air tap is formed by compressing the opposite sides of the intermediate portions of two soft films, said air tap formed with an insert slot in the center, the outer uncompressed ends of said two soft films having one film formed with an oblique cut surface, said air tap having its inner end not compressed, the inner opening of said insert slot of said air tap formed shrinking gradually.
