Shock-absorbing bag

Abstract

A shock-absorbing bag is formed of a single piece of sheet member folded up and sealed into a predetermined shape defining a holding space for holding an object. The sheet member has a first sheet layer, a second sheet layer sealed to the first sheet layer, at least one air chamber defined in between the first sheet layer and the second sheet layer, and an air valve provided at one of the first sheet layer and the second sheet layer through which air is driven into or forced out of the at least one air chamber.

What is claimed is:  
     
         1 . A shock-absorbing bag formed of a single piece of sheet member folded up and sealed into a predetermined shape defining a holding space for holding an object, said sheet member comprising a first sheet layer, a second sheet layer sealed to said first sheet layer, at least one air chamber defined in between said first sheet layer and said second sheet layer, and an air valve provided at one of said first sheet layer and said second sheet layer through which air is driven into or forced out of said at least one air chamber.  
     
     
         2 . The shock-absorbing bag as claimed in  claim 1 , wherein said sheet member includes two side panels, a front panel, a bottom panel, a back panel, and a top cover panel adapted for forming six sides of the shock-absorbing bag.  
     
     
         3 . The shock-absorbing bag as claimed in  claim 2 , wherein said at least one air chamber includes a plurality of air chambers respectively formed in said side panels, said front panel, said bottom panel, said back panel, and said top cover panel.  
     
     
         4 . The shock-absorbing bag as claimed in  claim 3 , wherein said air chambers are disposed in air communication with one another.  
     
     
         5 . The shock-absorbing bag as claimed in  claim 2 , further comprising connector means provided at said side panels, and a shoulder strap fastened to said connector means.  
     
     
         6 . The shock-absorbing bag as claimed in  claim 2 , further comprising fastener means adapted for fastening said top cover panel to said front panel to close said holding space.  
     
     
         7 . The shock-absorbing bag as claimed in  claim 1 , wherein said air valve is disposed inside said holding space.  
     
     
         8 . The shock-absorbing bag as claimed in  claim 1 , further comprising at least one pocket formed at one side of said sheet member.  
     
     
         9 . The shock-absorbing bag as claimed in  claim 1 , wherein said at least one air chamber comprises at least two separated subsidiary air chambers.
