[0016] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] Such as Figure 1As shown in the figure, a packaging food box made of straw provided by the present invention includes a box body 1 with an open side. The box body 1 includes a bottom plate 1.1. Three adjacent side plates are fixed vertically by iron nails above the bottom plate 1.1. A U-shaped structure is formed among the three vertical plates 1.2. Corresponding sliding grooves 3 are arranged in two relatively arranged vertical plates 1.2. A top plate 1.3 is fixed above the three vertical plates 1.2 by iron nails. A through groove is opened on one side of the top plate 1.3 close to the open side of the box body 1. An insertion plate 2 is inserted into the through groove, and the insertion plate 2 seals the open side of the box body 1.

[0018] In order to better push the insertion plate 2, a push groove 1.6 is arranged on the outer side surface of the insertion plate 2. Press the finger on the push groove 1.6 and then push the insertion plate 2 upward to open the box body 1.

[0019] Guide slide bars 1.5 are connected to the two opposite sides close to the open side in the box body 1. Each guide slide bar 1.5 is glued to the corresponding vertical plate 1.2. Guide grooves 1.7 are arranged on the two side surfaces of the insertion plate 2. Each guide slide bar 1.5 is slidably guided in the corresponding guide groove 1.7. The guide slide bars 1.5 are used for the up and down guiding of the insertion plate 2.

[0020] As Figure 2 and Figure 3 As shown in the figure, sliding grooves 3 are vertically arranged in two relatively arranged vertical plates 1.2. A relief groove 1.4 is arranged on the top plate 1.3. The relief groove 1.4 communicates with the two sliding grooves 3. A sliding plate 4 is slidably connected in each sliding groove 3. A fixing plate 5 is nailed above the two sliding plates 4. The fixing plate 5 is arranged above the box body 1. The fixing plate 5 can be inserted into the relief groove 1.4. By pulling the fixing plate 5, the two sliding plates 4 can be pulled to move up and down.

[0021] A through hole is opened on the fixing plate 5. A nut is adhesively fixed in the through hole. A support bolt 5.1 is threadedly connected in the nut. After lifting the fixing plate 5, by rotating the support bolt 5.1, the support bolt 5.1 moves downward until the lower end abuts against the relief groove 1.4 to support the fixing plate 5. A handle 5.2 is connected to the fixing plate 5. The handle 5.2 is a cloth belt handle. The two ends of the handle 5.2 are nailed to the fixing plate 5 by nails. The handle 5.2 can facilitate lifting the fixing plate 5.

[0022] Vertically fix two partitions 6 in the box body 1 by nails and glue. The two partitions 6 divide the interior of the box body 1 into three cavities 7. At the lower sides of both sides in each cavity 7, communication grooves 8 are provided. Each communication groove 8 communicates with the corresponding sliding groove 3. In each cavity 7, a placing plate 9 is arranged. Both ends of the placing plate 9 are fixed with sliding blocks by nails. The sliding blocks pass through the corresponding communication grooves 8. One side of the sliding block is connected and fixed to the corresponding sliding plate 4 by iron nails.

[0023] On each placing plate 9, lunch boxes 10 with open tops are arranged. The material of the lunch boxes 10 can be made of plastic, wood or metal. In order to make the lunch boxes 10 more compatible with the box body 1, in this embodiment, the material of the lunch boxes 10 is preferably wood material. That is, two positioning slide rails 9.1 are glued on each placing plate 9. The two positioning slide rails 9.1 on the same placing plate 9 are symmetrically arranged. At the bottom of each lunch box 10, two sliding grooves are provided. The corresponding positioning slide rails 9.1 are slidably connected in each sliding groove. The lunch boxes 10 are positioned by the positioning slide rails 9.1. When placing the lunch boxes 10, the lunch boxes 10 slide into the box body 1 along the positioning slide rails 9.1 until the lunch boxes 10 abut against the side walls of the box body 1.

[0024] At the top of each cavity 7, a cover plate 11 for covering the open mouth of the lunch box 10 is glued. When pulling the handle 5.2, the two sliding plates 4 move upward, thereby driving the lunch box 10 to move upward so that the cover plate 11 can cover the lunch box 10. In order to further ensure the temperature of the food, a sealing strip 12 is connected to the lower side of each cover plate 11 to ensure the sealing and heat preservation of the lunch box.

[0025] The above-mentioned plate-like structures are all made of straw-pressed boards. Using straw as raw material to make food boxes can not only turn waste into treasure, but also effectively prevent straw burning and environmental pollution by recycling a large amount of straw. Moreover, the price of straw is low and the production cost will be greatly reduced. In addition, most of the materials of this product are made of straw, giving a retro aesthetic feeling. In addition, it also has the characteristics of firmness and light weight. In addition, this product has good heat preservation effect. During the process of carrying, due to the weight of the box body 1 and the food itself, it will drive the cover connection between the lunch box 10 and the cover plate 11 to be tighter, further improving the sealing and heat preservation of the food.
