[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0026] Please refer to Figures 1-8 In the embodiments of the present application, a tin buckle iron box comprises a box body 1 and a box bottom cover 2. The box body 1 is hollow and has openings at both ends. The box bottom cover 2 can be buckled with the box body 1 to close the bottom opening of the box body 1. The box bottom cover 2 comprises a bottom plate 21 and a peripheral plate 22 connected to the outer periphery of the bottom plate 21. The middle part of the bottom plate 21 is protruded downward to form a protruding part 23. The first sealant 13 is arranged between the protruding part 23 and the peripheral plate 22. When the box body 1 is buckled with the box bottom cover 2, the peripheral plate 22 is folded towards the bottom plate 21. The bottom edge of the box body 1 is bent and extends into the space between the peripheral plate 22 and the bottom plate 21. The peripheral plate 22, the bottom plate 21 and the bottom edge of the box body 1 are attached to each other. The first sealant 13 is filled in the gap between the peripheral plate 22, the bottom plate 21 and the bottom edge of the box body 1.

[0027] The box body 1 is made of a base plate 11 by hooking the head and tail ends of the base plate 11. When the base plate 11 is in an unfolded state, the head end of the base plate 11 is bent to form a V-shaped hooking part 12. The second sealant 24 is arranged between the two side edges of the hooking part 12 and close to the connection positions of the two side edges. The tail end of the base plate 11 is bent to form a folded edge 14. When the base plate 11 is connected at the head and tail ends to form a hollow shape, the folded edge 14 extends into the space between the two side edges of the hooking part 12. The two side edges of the hooking part 12 and the folded edge 14 are attached to each other. One of the two side edges of the hooking part 12 and the base plate 11 are attached to each other. The second sealant 24 is filled in the gap between the two side edges of the hooking part 12 and the folded edge 14.

[0028] Thus, the iron box is formed by the base plate 11, the bottom plate 21 and the peripheral plate 22, which is simple and reasonable in structure, low in manufacturing cost, suitable for batch production, and can improve the air tightness and water tightness among the base plate 11, the bottom plate 21 and the peripheral plate 22 by filling the first sealant 13 and the second sealant 24 in the gaps at the connecting positions of the base plate 11, the bottom plate 21 and the peripheral plate 22, so as to prevent the food contained in the iron box from being damp and deteriorated in a short time. In addition, the V-shaped hooking part 12 and the protruding part 23 provide sufficient filling space for the first sealant 13 and the second sealant 24.

[0029] The materials of the box body 1 and the box bottom cover 2 are tinplate.

[0030] The gap a between the peripheral plate 22 and the protruding part 23 is 2.2 mm.

[0031] The distance b between the inner side of the bottom plate 21 and the bottom end surface of the box body 1 is 1 mm.

[0032] The injection width c of the first sealant 13 is 1.3 mm, and the injection thickness d of the first sealant 13 is 0.4 mm.

[0033] The injection width e of the second sealant 24 is 1.5 mm, and the injection thickness f of the second sealant 24 is 1 mm.

[0034] The distance g between the inner side of the hooking part 12 and the outer side of the base plate 11 is 0.85 mm, and the length h of one side of the hooking part 12 is 3.5 mm.

[0035] The connection tightness among the base plate 11, the bottom plate 21 and the peripheral plate 22 is improved by reasonable size setting.

[0036] In order to improve the food safety, the first sealant 13 and the second sealant 24 are made of edible materials.

[0037] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Accordingly, the embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the present application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
