Embodiment 1, referring to Fig. 1, Fig. 2, Fig. 3, base plate metal pattern at 2 quarter one, with the hard base plate 2 of non-toxic plastic polyethylene from high pressure process material single injection-molded, it is identical to do two block sizes with nontoxic software plastics polyethylene from high pressure process again, a pair of side plate (film) 3, use two structures of metal (nontoxic) or plastics (nontoxic) system then, the framework 1 that size is the same, with the same square plate (film) 4 of two sizes of nontoxic software plastics polyethylene from high pressure process system, side's plate (film) 4 glueds joint into side plate (film) admittedly with framework 1 and then the pair of side plates (film) that framework 1 side's plate 4 is formed is contained on the base plate 2, and make side plate (film) and base plate 2 can locate self-locking, then another is contained in the place, peripheral slit that forms side's body container on the base plate 2 to side plate (film) and is sealed, cover lid 6 and be a folding lunch box with strip of paper used for sealing.

The operating process of present embodiment 1 is as follows: at first open lid 6, pull open a pair of side plate of forming with framework 1 and square plate (film) 4 (film) then, make framework 1 by the elasticity of self and four jiaos of locked grooves, the 5 location self-lockings of base plate 2, and make a pair of software non-toxic plastic side plate (film) 3 be in tensioning state to become side's body container at this moment, when not having a dinner, firmly a pair of side plate of being made up of framework 1 and non-toxic plastic polyethylene from high pressure process side plate (film) 4 (film) is inwardly depressed with base plate 2 and be close to, lid 6 and base plate 2 are fastened be a thin square folded body lunch box then.

Embodiment 2 is referring to Fig. 4, shown in Figure 5, folded chassis is carved a metal pattern, be placed on hinge 11 in the mould and folded chassis 10 usefulness non-toxic plastic polypropylenes 2600 single injection-moldeds, it is identical to do a pair of size with polypropylene 2600, the software side plate (film) 9 that size is the same, use metal (nontoxic) or plastics (nontoxic) to make a pair of structure then, the framework 8 that size is the same, with two sizes of nontoxic software plastics polypropylene 2600 systems, equirotal side's plate (film) 7 is contained in this on base plate 10 side plate 9 side plate and another then accordingly, form side's body container, slide fastener 13 is fixed on dermatotome 12 peripheries makes slide fastener 13 draw back gathering freely, base plate 10 is glued to forms an integral body on the dermatotome 12.

The operating process of present embodiment 2 is as follows: when people have a dinner, unzip 13, open folded chassis 10, pull open the side plate that a correspondence is made up of framework 8 and square plate (film) 7 then, framework 8 is stuck in by self elasticity in the draw-in groove 14 of base plate 10 locatees self-locking, and making two software side plates 9 be in tensioning state, be side's body container this moment.When people do not have a dinner, firmly pinch framework 8 both sides, make framework 8 break away from draw-in groove 14 and be close to base plate 10, the folding thereupon and base plate 10 of biside plate (film) 9, folding accordingly base plate 10 again, draw slide fastener 13 in, be side's body leather goods folding lunch box.
