The utility model is a kind of structure of lunch box, please cooperate referring to Fig. 1-2, and it mainly is made up of through the vacuum seaming lunch box body 10 and lid 11.

Wherein: this lunch box body 10 is a metal material, cooperate the mould punching press (to cooperate the mould punching press to make the method for product through machine because of seeing through machine, the mode that the relevant industry of system is commonly used is so the detailed content of relevant in the literary composition " machine cooperates mould to stamp out finished product " will not be given unnecessary details.) structure that formed.

These lid 11 homology metal materials, its central part forms loam cake 111, glutinous being provided with opened element 2 on loam cake 111, in addition, this loam cake 111 and lid 11 adjacent rings enclose and form groove 112 (cooperating referring to Fig. 3), these groove 112 two ends join with linking part 113, and the structure person that this 113 while of linking part lid 11 and loam cake 111 link to each other; This bottom portion of groove 1122 forms two parallel recess 1121 in loam cake 111 inner face ends, but this groove 112, linking part 113 and recess 1121 all are a punching press is shaped in lid 11, in addition, this bottom portion of groove 1122 is equipped with projection 114 in loam cake 111 outside end either side linking parts 113, and the circumference of this projection 114 just is the reverse side of loam cake 111 inner face end bottom portion of groove 1122 recess 1121.

The end is in lunch box body 10 food of packing into, again with lid 11 and lunch box body 10 with seaming mode secure bond for it, and (method of vacuum-packed various foods, article is that relevant industry is commonly used it, does not repeat them here to make its lunch box 10 inside be vacuum state.), so be the structure of the utility model easy-opening safety lunch box.

Because of the utility model is a metal material, has suitable hardness, so food vacuum seaming also can be able to be accepted long-time, long-distance transporting, because of the thing of suffering from indigestion with the mode bag of vacuum seaming, high temperature sterilization, can at room temperature store for a long time again so need not to use antioxidant.

Right emphasis is that the utility model constitutes with metal material, but since at the beginning of the design be at the modern like convenient custom set it, so need only when opening " single-point " cemented unlatching element 2 in loam cake 111 is taken off, be placed in again on the projection 114 of loam cake 111 (shown in Fig. 4), rotate afterwards and open element 2 with pulling projection 114, just can be via following principle and step, easily and safety reach the purpose of opening lunch box:

1. be formed with two parallel recess 1121 (cooperating referring to shown in Fig. 1-3) on the bottom portion of groove 1122 of loam cake 111 inner face ends, the formation of its recess 1121 still makes bottom portion of groove 1122 paths occur;

Moreover, in the loam cake 111 outside end grooves 112, its circumference of set projection 114 just is the reverse side at 1122 liang of parallel recesses places 1121 of loam cake 111 inner face end bottom portion of groove;

3. so be enclosed within (cooperation is referring to Fig. 4) on the projection 114 when the consumer will open element 2, and rotate when opening element 2 with pulling projection 114, this bottom portion of groove 1122 just can be owing to the reason that has recess 1121, and can be when projection 114 is unlocked element 2 pullings, follow recess 1121 and by projection 114 pull-ups, and prolong outstanding recess 1121 and drawn back (cooperation) referring to Fig. 5 by projection 114, also make loam cake 111 be raised this moment indirectly, again with the reason that is formed with recess 1121 because of bottom portion of groove 1122, so when bottom portion of groove 1122 during by projection 114 pull-ups, its bottom portion of groove 1122 all can not form sharp keen burr (cooperating referring to Fig. 6) with groove 112, and go to when holding in addition when opening element 2 those ends by linking part 113, this loam cake 111 just can open (shown in Fig. 7) fully, and mat linking part 113 and linking for it with lid 11;

And because the utility model is a quite creative creation, can effectively improves and commonly use the shortcoming that lunch box causes, hereat the applicant will additionally propose following explanation at this:

1. because the design of recess, so make bottom portion of groove when being pulled away from groove, can not form sharp keen burr in the parting surface of its bottom portion of groove and groove, make the consumer when the unlatching lunch box, do not have by the anxiety of incised wound;

2. in addition also because of the design of recess, so can allow bottom portion of groove follow recess to be pulled away from groove easily simultaneously, easily be easy to open lunch box, again because loam cake is to be within the groove with the lid place of separation, so when the consumer eats with regard to mouth with lunch box, its oral area only touches the groove of lid front end, does not also have by the anxiety of incised wound.

3. in addition, because of on the utility model the lid open fully in, intercalationly on it still link to each other for it with lid with linking part, so lunch box is edible finish after, also dish can be considered to be worth doing residue and place in the lunch box body, and with on the lid that loam cake turns back with the lunch box body links to each other, again the lunch box body is thrown into garbage can, so just can not cause the secondary pollution of dish bits residue, also can not allow the consumer have an opportunity loam cake is arbitrarily abandoned, compliance with environmental protection requirements and avoid causing potential danger.

Moreover, because the utility model system makes with the metal material, after so the food consumption in the lunch box finishes, still the lunch box of using can be concentrated, reclaiming profit again has, and avoids causing environmental pollution, can say that system quite meets the creation of environmental protection notion, and except rectangle, the utility model also can be along with the difference of the food of packing, and stamps out moulding as cylindric classes such as (referring to Fig. 8) with machine.
