3D storage bag having a 3D storage chamber

Abstract

A 3D storage bag includes opposing flexible plastic front and back panels, the two opposite lateral sides of each of the flexible plastic front and back panels each having a first segment and second and third segments respectively extended from the top and bottom ends of the first segment, the first segments of the two opposite lateral sides of the flexible plastic front and back panels being respectively sealed together, a flexible plastic top panel bonded to the flexible plastic back panel and the second segments of the two opposite lateral sides of the flexible plastic front and back panels and defining with the flexible plastic front panel an opening, a flexible plastic bottom panel bonded to the bottom sides of the flexible plastic front and back panels and the third segments of their two opposite lateral sides of the flexible plastic front and back panels, and a fastening tape for closing/opening the opening.

1 . A 3D storage bag, comprising:
 opposing flexible plastic front panel and flexible plastic back panel each having a top side, a bottom side and two opposite lateral sides, the two opposite lateral sides of each of said flexible plastic front panel and flexible plastic back panel each having a first segment, a second segment extended from a top end of said first segment and a third segment extended from a bottom end of said first segment, the first segments of the two opposite lateral sides of said flexible plastic front panel and said flexible plastic back panel being respectively sealed together;   a flexible plastic top panel having three of four sides thereof respectively bonded to a top side of said flexible plastic back panel and the second segments of the two opposite lateral sides of said flexible plastic front panel and flexible plastic back panel and the other one of the four sides in proximity to and spaced from the top side of said flexible plastic front panel by an opening;   a flexible plastic bottom panel having four sides thereof respectively bonded to the bottom sides of said flexible plastic front panel and said flexible plastic back panel and the third segments of the two opposite lateral sides of said flexible plastic front panel and said flexible plastic back panel; and   a fastening tape adapted for closing/opening the opening between said flexible plastic front panel and said flexible plastic top panel, said fastening tape comprising a male fastening tape member fixedly fastened to an inner face of said flexible plastic top panel and a female fastening tape member fixedly to an inner face of said flexible plastic front panel and fastenable with said male fastening tape.   
     
     
         2 . The 3D storage bag as claimed in  claim 1 , further comprising an exhaust valve bonded to said flexible plastic front panel and adapted for exhaust of air out of the 3D storage bag. 
     
     
         3 . The 3D storage bag as claimed in  claim 2 , wherein said exhaust valve comprises a valve body bonded to said flexible plastic front panel and defining therein an air passage in communication between the space inside the 3D storage bag and the atmosphere, a valve flap set in said air passage inside said valve body and movable to open/close said air passage, and a valve cap fastened to said valve body to keep said valve flap in said valve body, said valve cap having a plurality of exhaust holes. 
     
     
         4 . The 3D storage bag as claimed in  claim 1 , further comprising a hanger bonded to said flexible plastic front panel near one side thereof, said hanger comprising an external hanging hook suspending outside the 3D storage bag and an internal hanging hook suspending inside the 3D storage bag. 
     
     
         5 . The 3D storage bag as claimed in  claim 4 , wherein said hanger further comprises an exhaust valve bonded to said flexible plastic front panel and fixedly mounted on a top end of said internal hanging hook and a valve cap capped on the exhaust valve and affixed to a bottom end of said external hanging hook. 
     
     
         6 . The 3D storage bag as claimed in  claim 1 , wherein the third segments of the two opposite lateral sides of said flexible plastic front panel and said flexible plastic back panel are bonded together.
