Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained without creative work by the ordinary skilled person in the art all belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

Example 1:

referring to fig. 1 to 3, an aluminum foil four-cell lunch box is preferred, wherein the box body is made of aluminum foil and includes a box body and a box cover (not shown) fastened to the box body, the box body is rectangular, the shape of the box cover (not shown) is matched with the shape of the opening of the box body, in this embodiment, the box body is about 24.5mm long and about 21mm wide, four cell slots, namely, a first cell slot 1, a second cell slot 2, a third cell slot 3 and a fourth cell slot 4, are arranged in the box body, the depth of the cell slots is about 4mm, the second cell slot 2, the third cell slot 3 and the fourth cell slot 4 are rectangular, the cell bodies of the second cell slot 2, the third cell slot 3 and the fourth cell slot 4 are trapezoidal, and the bottom of the box body is recessed corresponding to the four cell slots respectively to form a cell wall 8 of each cell slot; the periphery of the opening of the box body is horizontally and circularly provided with a box body outer edge 5, one end of the box body outer edge 5 is a free end, the other end of the box body outer edge is connected with a box body step 14, the box body step 14 is connected with a box wall 8, and the box wall 8, the box body step 14 and the box body outer edge 5 are integrally formed; first minute check groove 1, second minute check groove 2, third minute check groove 3 and fourth minute check groove 4 surround and form central boss 6 towards the cell wall 8 of one side at the box body center, be provided with constant head tank 7 on the central boss 6, preferably, the quantity of constant head tank 7 is two. The positioning column (not shown in the figure) on the aluminum foil processing equipment presses the positioning groove 7, the positioning groove 7 is limited in position and quantity, so that the aluminum foil lunch box is prevented from easily deviating during processing and manufacturing, the expected lunch box shape can be obtained, the attractiveness of the aluminum foil lunch box is improved, the processing efficiency is improved, and the generation of unqualified products is reduced.

Preferably, the box body outer edge 5 is a folded edge structure which is folded inwards along a connecting line of the box body step 14 and the box body outer edge 5 and is used for sealing a box cover (not shown in the figure). The box body outer edge of aluminium foil is easily buckled, and the leakproofness is good moreover, and the setting of overlap limit structure has improved packing efficiency.

More preferably, the edge folding structure is a structure in which high edge portions 501 and curled edge portions 502 are sequentially alternated, the high edge portions 501 are disposed at four corner corners of the outer edge 5 of the box body, the curled edge portions 502 are disposed in the direction along the length and width of the box body, and the curled edge portions 502 are bent upward and extended and then curled outward to form curled edges. The high edge 501 improves the strength of the outer edge 5 of the box body of the lunch box, and is convenient for users to hold.

Preferably, be close to box body step 14 position between first branch check groove 1 and the second branch check groove 2 and be provided with first boss 9, be close to box body step 14 position between second branch check groove 2 and the third branch check groove 3 and be provided with second boss 10, be close to box body step 14 position between third branch check groove 3 and the fourth branch check groove 4 and be provided with third boss 11, be close to box body step 14 position between fourth branch check groove 4 and the first branch check groove 1 and be provided with fourth boss 12, equal level is provided with strengthening rib 13 on first boss 9, second boss 10, third boss 11 and the fourth boss 12.

Preferably, the 8 surfaces of the two cell walls of the two adjacent cell slots facing outwards form an included angle of 30-50 degrees. The included angle is less than 30 degrees, so that the volume of the lunch box made of the same aluminum foil material is reduced, and the difficulty of processing and manufacturing is increased by more than 50 degrees. The included angle is more preferably 40 °.

Example 2:

the difference from embodiment 1 is that the edge folding structure is a high-edge structure. The high limit structure is the same structure with the high limit portion 501 in embodiment 1, and the height of the high limit structure is about 5mm, so that the box body is easier to bend and press inwards quickly along the 5 peripheral high limit structures, and the periphery of the box cover (not shown in the figure) can be sealed by the high limit structure, thereby improving the tightness of the lunch box.

Example 3:

the difference from the embodiment 1 is that the outer edge 5 of the box body is a curled edge structure, and the curled edge structure is curled outwards after being bent upwards to form a curled edge. The edge-curling structure greatly enhances the strength of the outer edge 5 of the box body of the lunch box, particularly the strength of the corners around the lunch box, so that the overall strength of the lunch box is greatly improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
