ABSTRACT:
A handle structure for cartons has a handle body and two symmetrical fastening pairs disposed at two ends of the handle body. Each fastening pair includes an inside L frame, an outside L frame, and a flexible ligament connecting the inside L frame and the outside L frame. While the locations of the inside L frame and the outside L frame are shifted through the flexible ligament, the inside fastening strip of the inside L frame and the outside fastening strip of the outside L frame can adjoin closely. Moreover, the inside unfolded strip of inside L frame and the outside unfolded strip of the outside L frame are led to a status as two wings spanned in parallel at both sides of the flexible ligament.
