Problems solved by technology

[0003] The structure of the above-mentioned lunch box can meet the basic function of loading items, but in the production process, the space between the pressing surface and the box body is formed by direct folding, and the folding position is usually judged by the operator based on experience. Not only is the position of the folding line unstable, but also after the folding is performed on the basis of the same material and the same thickness of the box body, the lower pressing edge will generate a large restoring force, making it difficult to shape the shape of the folding

Embodiment 1

[0053] A lunch box with folded edges and corners, see figure 1 , including the inner box body 1. In this embodiment, the shape of the inner box body 1 is a square structure. The inner box body 1 is provided with a accommodating slot 2, and the inner box body 1 is provided with a box mouth 3. The box of the inner box body 1 Port 3 is set up.

[0054] see figure 1 , the inner box body 1 is provided with a folding piece 4, the folding piece 4 is located at the box mouth 3, the number of the folding piece 4 is four, and the folding point between the folding piece 4 and the inner box body 1 is A folding line 5 is provided, and the folding line 5 is formed by a plurality of through grooves penetrating through the inner box body 1 arranged in a straight line at intervals.

[0055] see figure 1 as well as figure 2 , also includes a box cover 6, the periphery of the box cover 6 is provided with a cover edge 7, and the inner side of the cover edge 7 is provided with a cartridge pro...

Embodiment 2

[0058] The difference from Embodiment 1 is: see image 3 , and also includes an outer box body 9 , and the outer box body 9 is sleeved on the outside of the inner box body 1 .

[0059] see image 3 as well as Figure 5 , between the inner box body 1 and the outer box body 9 is also provided with a clamping rod assembly 10, the clamping rod assembly 10 includes three clamping rod segments 11 arranged in separate parts, and two ends of the clamping rod segment 11 are respectively provided with plug The end 111 and the socket 112, the plug end 111 on the clamping rod segment 11 can be inserted into the socket 112 of another adjacent clamping rod segment 11, and a connecting line 12 is connected between the two adjacent clamping rod segments 11.

[0060] see Figure 4 , Figure 5 as well as Image 6 , the outer side wall of the inner box body 1 includes a front side wall 13, a rear side wall 14, a left side wall 15, a right side wall 16, a lower side wall 17, the front side w...

Embodiment 3

[0066] Embodiment 3: On the basis of Embodiment 3, the following structure is added.

[0067] see Figure 7 , in the outer box body 9, there are two fixed components 26, each fixed component 26 includes a devil stick 24, a rotating rod 25, and the two ends of the rotating rod 25 are the trigger end 251 and the bonding end 252, respectively. The middle part is rotatably connected to the inner box wall of the outer box body 9, and the two fixing components 26 are respectively located at the outer box body 9 near the left side wall 15 and the right side wall 16. The devil stick 24 includes a male stick 241, a negative stick 242, the male adhesive sheet 241 is installed on the bonding end 252, and the female adhesive sheet 242 is installed on the lower side wall 17 of the inner box body 1. After the inner box body 1 squeezes the trigger end 251 of the rotating rod 25, the rotating rod 25 is rotated, and the male adhesive sheet 241 of the rotational bonding end 252 is bonded to th...

Abstract

The invention provides a lunch box with folded edges and corners and a method of using the lunch box. The present invention includes an inner box body, an accommodating groove is arranged in the inner box body, a box mouth is arranged on the inner box body, a folded sheet is arranged on the inner box body, the folded sheet is located at the box mouth, and the folded piece and the inner box body are connected with each other. There is a folding line at the turning point between the two, and the folding line is formed by a plurality of through grooves penetrating through the inner box body, which are arranged in a straight line at intervals. The restoring force of the folded sheet is greatly reduced, and the difficulty of folding and shaping is greatly reduced. In addition, the inner box can be made of starch, plant fiber, water repellent, and mold release agent after being stirred and mixed to be called mud, and then the mud and the lining paper are molded together at high temperature. The paper material is biodegradable and has certain environmental protection properties.

Description

technical field [0001] The present invention relates to lunch boxes, in particular, to a lunch box with folded edges and corners and a method of using the lunch box. Background technique [0002] For example, the Chinese utility model patent lunch box with the publication number CN2235746Y, its structure mainly includes a box body with a recessed part in the middle, a long strip-shaped pressing surface extending in front of the top edge of the box body and on both sides, and the upper cover The extending upper pressing surfaces on both sides of the bottom edge face each other and fit each other, and the connection between the upper cover and the box body is also completed by the mutual cooperation between the tenon on the upper cover and the hole on the lower pressing surface. [0003] The above lunch box structure can meet the basic item loading function, but in the production process, the direct folding is used between the pressing surface and the box body, and the folding...
