[0002] With the improvement of people's living standards, convenient and fast dining methods have become the mainstream choice of people. Lunch boxes are of great significance in improving the convenience of dining. Paper lunch boxes use paper as the base material, and the surface is covered with paraffin and polyethylene coatings for food packaging or holding cold and hot foods. The use of paper lunch boxes is easy to recycle, which can greatly reduce pollution to the environment and has very important environmental protection value. Although paper lunch boxes are made of paper materials, when recycling lunch boxes, the lunch boxes with open lids are large in size, and ordinary trash cans are difficult to put in or can only accommodate a few lunch boxes, which seriously affects the waste recycling of paper lunch boxes. Lunch boxes with printed lids are put into trash cans. Because the food grease and water attached to the inner wall of the lunch box are difficult to clean, it is difficult to discharge the liquid attached to the lunch boxes recycled into the trash can. The paper lunch boxes immersed in liquids for a long time will invade the liquid, affecting recycling. Summary of the invention

DETAILED DESCRIPTION

[0024] like Figure 1-4As shown, a disposable environmentally friendly lunch box for arranging and classifying dishes comprises a lunch box body 1 and a cover 2 covered on the lunch box body 1, wherein the lunch box body 1 comprises a first receiving chamber monomer 11 and a second receiving chamber monomer 12, wherein the first receiving chamber monomer 11 is fixed on the second receiving chamber monomer 12, and a plurality of vegetable grids for arranging dishes are formed between the first receiving chamber monomer 11 and the second receiving chamber monomer 12, and a placement groove 21 and a clamping strip 22 are further provided on the upper surface of the cover 2, wherein the placement groove 21 and the clamping strip 22 are provided for placing a spoon through the placement groove 21 and clamping the tail of the spoon in the clamping strip 22 for fixing. The chopsticks can also be fixed by the clamping strip 22. In order to solve the technical problem described in the background technology, the present invention fixes and forms the dish grid by clamping the first receiving chamber monomer 11 and the second receiving chamber monomer 12. When the present invention needs to be recycled, the first receiving chamber monomer 11 and the second receiving chamber monomer 12 can be directly disassembled by stepping on, tearing or splitting, thereby reducing the occupied area of ​​the lunch box. Moreover, the soup can be completely discharged when the first receiving chamber monomer 11 and the second receiving chamber monomer 12 are disassembled, thereby fundamentally solving the problem of food grease, water and the like attached to the inner wall of the lunch box being difficult to clean.

[0025] The first receiving chamber monomer 11 can be fixed to the second receiving chamber monomer 12 by bonding, clamping, etc. In order to further fix the second receiving chamber monomer 12 and prevent the vegetable grid formed by the first receiving chamber monomer 11 and the second receiving chamber monomer 12 from collapsing or bending during transportation after the vegetables are loaded, in the present invention, a positioning hole is provided in the middle of the lunch box body 1, and a corresponding limiting rod 23 is provided at the lower end of the lid 2. When the lid 2 is covered on the lunch box body 1, the limiting rod 23 is embedded in the positioning hole, and the limiting rod 23 is inserted into the positioning hole. Figure 2 , 4 As shown, the positioning hole is formed on the middle surface of the first storage chamber monomer 11 and the second storage chamber monomer 12 by means of the snap fit between the two. Therefore, the positioning hole is fixed by means of a limiting rod 23 embedded in the positioning hole. The limiting rod 23 can respectively form a restraining effect on the first storage chamber monomer 11 and the second storage chamber monomer 12, thereby avoiding the above-mentioned problem in the transportation diagram.

[0026] In order to prevent the vegetable juice contained in the vegetable grid from overflowing, an impermeable bottom sheet 14 is wrapped below the first receiving chamber monomer 11 and the second receiving chamber monomer 12, and an impermeable fixing sheet 13 is attached to the connecting end of the first receiving chamber monomer 11 and the second receiving chamber monomer 12, and the impermeable fixing sheet 13 extends to the surface of the impermeable bottom sheet 14 and the upper part of the first receiving chamber monomer 11, respectively, so as to cover the gap at the connecting end of the first receiving chamber monomer 11 and the second receiving chamber monomer 12 through the impermeable fixing sheet 13, and strengthen the closure of the first receiving chamber monomer 11 and the second receiving chamber monomer 12 through the impermeable fixing sheet 13. Figure 4 As shown, a sheet-like waterproof layer is provided at the lower end of the first receiving chamber monomer 11 and the lower end of the second receiving chamber monomer 12. When the first receiving chamber monomer 11 is fixed on the second receiving chamber monomer 12, the two sheet-like waterproof layers overlap, and the two sheet-like waterproof layers can be directly stacked by bonding, or can be bonded by a food-grade adhesive. Because when loading dishes, rice, or soup, the weight of the food will squeeze the first receiving chamber monomer 11 or the second receiving chamber monomer 12 placed on the upper part, thereby improving the tightness between the first receiving chamber monomer 11 and the second receiving chamber monomer 12, and the lower side of the sheet-like waterproof layer is also wrapped by a waterproof bottom film 14, so that the soup will not overflow even if a gap appears between the two sheet-like waterproof layers.

[0027] like Figure 4 As shown, the cross-sections of the first receiving chamber monomer 11 and the second receiving chamber monomer 12 are both G-shaped structures, and the middle parts of the first receiving chamber monomer 11 and the second receiving chamber monomer 12 both have a bending portion, and the two bending portions are staggered with each other. The purpose of such arrangement is to form a positioning hole in the middle part of the first receiving chamber monomer 11 and the second receiving chamber monomer 12 with a G-shaped structure when the two are fixed, and to allow the first receiving chamber monomer 11 and the second receiving chamber monomer 12 to overlap, thereby improving the closure.

[0028] Furthermore, a first positioning groove 111 is provided at the lower end of the bent portion of the first receiving chamber monomer 11, and a corresponding third positioning groove 121 is provided at the upper end of the bent portion of the second receiving chamber monomer 12. When the first receiving chamber monomer 11 is fixed on the second receiving chamber monomer 12, the first positioning groove 111 is embedded in the third positioning groove 121 and interlaced with each other. This arrangement is to form the above-mentioned vegetable grid, and the vegetable grid formed in this way can be distinguished from the lunch boxes in the prior art. The lunch boxes in the prior art are all formed by heating plastic and pressing it. When recycled, the main body and the vegetable grid will occupy a large amount of space. However, the lunch box in the present invention can be recycled by removing the first receiving chamber monomer 11 from the second receiving chamber monomer 12.

[0029] It should be explained that the lunch box in the present invention is made of degradable material, and a waterproof layer is applied on the surface of the material when making the lunch box to play a hydrophobic role.

[0030] Furthermore, the head end of the first receiving chamber monomer 11 and the head end of the second receiving chamber monomer 12 respectively extend over the tail end of each other and form a covering surface, and the anti-seepage fixing sheet 13 is respectively adhered to the two covering surfaces. Such a setting can reduce the gap between the first receiving chamber monomer 11 and the second receiving chamber monomer 12 through the covering surface, and when the anti-seepage fixing sheet 13 is used for bonding and fixing, the first receiving chamber monomer 11 and the second receiving chamber monomer 12 can be fixed at the same time.

[0031] In addition, a second positioning groove 112 is provided on the first receiving chamber monomer 11 near the covering surface of the second receiving chamber monomer 12, and a fourth positioning groove 122 is provided on the second receiving chamber monomer 12 near the covering surface of the first receiving chamber monomer 11, and a fifth positioning groove 131 is provided on the lower end of the anti-seepage fixing plate 13. The second positioning groove 112 and the fourth positioning groove 122 are respectively engaged with the fifth positioning groove 131 on the adjacent anti-seepage fixing plate 13. The advantage of such a setting is that while the anti-seepage fixing plate 13 is bonded and fixed, the stability of the connection between the anti-seepage fixing plate 13 and the first receiving chamber monomer 11 or the second receiving chamber monomer 12 can be increased by engaging, that is, a limiting function is formed by the fifth positioning groove 131, so as to avoid the anti-seepage fixing plate 13 from being offset or formed due to various reasons after the first receiving chamber monomer 11 and the second receiving chamber monomer 12 are bonded.

[0032] Furthermore, the anti-seepage fixing sheet 13 is divided into two parts, left and right, by the fifth positioning groove 131 . The left and right parts of each anti-seepage fixing sheet 13 are respectively in contact with the surface of the first accommodation chamber monomer 11 and the second accommodation chamber monomer 12 .

[0033] Furthermore, the edge of the anti-seepage bottom film 14 has a raised layer, which is attached to the surface of the first storage chamber monomer 11 and the second storage chamber monomer 12. The role of the raised layer is not only to wrap the first storage chamber monomer 11 and the second storage chamber monomer 12, but the more important purpose is to form a lateral limiting function for the first storage chamber monomer 11 and the second storage chamber monomer 12, and cooperate with the cover 2 to fix the first storage chamber monomer 11 and the second storage chamber monomer 12 at the same time, and as Figure 3As shown, the cross-section of the lid 2 is a "bow"-shaped structure, and the inner diameter of the middle part of the lid 2 is smaller than the outer diameter of the upper part of the lunch box body 1. Therefore, when the lid 2 is placed on the lunch box body 1, the lunch box body 1 can be deformed by squeezing, and its upper part can be squeezed into the lid 2. Such a design can effectively prevent the soup from overflowing, and improve the fixation of the lid 2 to the lunch box body 1, so that it will not fall off easily.

[0034] Furthermore, the head end of the first storage chamber monomer 11 is located inside the second storage chamber monomer 12, while the tail end extends outside the second storage chamber monomer 12 and fits with the surface of the second storage chamber monomer 12. The head end of the second storage chamber monomer 12 is located inside the first storage chamber monomer 11, but the tail end is outside the first storage chamber monomer 11 and fits with the surface of the first storage chamber monomer 11. The purpose of such arrangement is to form an overlapping area between the first storage chamber monomer 11 and the second storage chamber monomer 12, and to use the overlapping area to increase the tightness between the two.

[0035] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
