Foldable carrying handle for a portable lunchbox

A foldable carrying handle used for a portable lunch-box, made of plastic and having seven pieces which are hingedly interconnected into one-part bar-shaped body and comprising:

• a cross bar having the same width as said lunchbox and positioned at the center of said bar-shaped body;
• two upper overlapping pieces symmetrically disposed at both ends of said cross bar and hingedly interconnected thereto through slimmer inner edges in such a way that top slots formed are directed outwards;
• two lower overlapping pieces symmetrically disposed at outer ends of both upper overlapping pieces and hingedly interconnected thereto through slimmer outer edges in such a way that middle slots formed are directed inwards;
• and
• two positioning pieces symmetrically disposed at outer ends of both lower overlapping pieces and hingedly interconnected thereto through slimmer inner edges in such a way that lower slots formed are directed outwards, a finger-shaped fastener being positioned on the inner side of said positioning pieces, respectively;
• wherein said finger-shaped fasteners of said two positioning pieces are inserted into connection holes at both sides of said lunchbox in such a way that said cross bar is situated atop while said upper overlapping pieces and said lower overlapping pieces vertically extend at both sides of said cross bar, thereby forming an inverted U-shaped carrying handle, and wherein said upper overlapping pieces and said lower overlapping pieces are inwardly folded at said edges when said cross bar is pressed downwards;
• and
• wherein two corresponding protruding pieces are formed at both sides of each of said lower overlapping pieces, and wherein in folding said carrying handle, said protruding pieces are engaged into indentations of said lower overlapping pieces and said cross bar for fixing said carrying handle in place.
