[0023] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the bottle body 1 includes a bottle body 101, a bottle mouth 102 and a clamping ring 103. The top of the bottle body 101 is fixedly connected to the bottom of the bottle mouth 102, and the outer wall of the bottle mouth 102 is provided with a bottle mouth external thread. The outer wall of the bottom of the bottle mouth 102 is movably clamped with the inner wall of the clamping ring 103. Food is loaded into the bottle body 101, and the bottle body material is a degradable material.
[0024] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the carrying ring 2 is composed of two connecting columns 201, a handle 202 and a hanging ring 203. One end of the two connecting columns 201 is fixedly connected to the two sides of the bottle body 101 respectively, and two connecting through holes are respectively arranged inside the two ends of the handle 202. The inner walls of the two connecting through holes are movably connected to the outer walls of the two connecting columns 201 respectively, and one side of the handle 202 is fixedly connected to one side of the hanging ring 203. By rotating the handle 202 to a vertical direction, the entire plastic bottle can be carried by hand, and the bottle can be hung on the hook through the hanging ring 203 for easy carrying and transportation.
[0025] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sealing cover 3 includes a sealing cover body 301, a first sealing ring 302 and two clamping blocks 303. The inner wall of the sealing cover body 301 is provided with a sealing inner thread, and the inner wall of the sealing inner thread is threadedly connected to the outer wall of the outer thread of the bottle mouth. The outer wall of the sealing cover body 301 is provided with a sealing outer thread, and the inner top wall of the sealing cover body 301 is movably abutted against the top of the first sealing ring 302. The two sides of the bottom of the sealing cover body 301 are respectively fixedly connected to one side of the two clamping blocks 303, and the top of the sealing cover body 301 is respectively provided with four limiting through holes. The sealing cover body 301 is rotated, and the sealing cover body 301 is threadedly connected to the bottle mouth 102 through threads. The first sealing ring 302 at the inner top of the sealing cover body 301 abuts against the top of the bottle mouth 102 to play a sealing role.
[0026] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the drying box 4 is composed of four sealing limit blocks 401, four limit columns 402, four limit springs 403 and a drying box body 404. The bottoms of the four sealing limit blocks 401 are respectively fixedly connected to the tops of the four limit columns 402, and the outer walls of the four limit columns 402 are respectively movably engaged with the inner walls of the four limit springs 403, the bottoms of the four limit springs 403 are respectively movably abutted against the top of the sealing cover 301, and the bottoms of the four limit columns 402 are respectively fixedly connected to the top of the drying box body 404. When the sealing limit block 401 is pressed down, the sealing limit block 401 is pressed down to drive the limit columns 403 to be pressed down, and the limit columns 403 are pressed down to drive the drying box body 404 to be pressed down. The downward pressing of the drying box body 404 can leave a gap so that the desiccant in the drying box body 404 can dry the food. At the same time, the drying box body 404 also effectively reduces the risk of food contamination caused by desiccant damage.
[0027] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the bottle cap 5 includes a bottle cap body 501, a second sealing ring 502 and an anti-slip ring 503. The inner wall of the bottle cap body 501 is provided with an inner thread of the cap body, and the inner wall of the inner thread of the cap body is threadedly connected with the sealing outer thread. The inner top wall of the bottle cap body 501 is movably abutted with the tops of the four limit blocks 401 respectively, and the inner top wall of the bottle cap body 501 is movably abutted with the top of the second sealing ring 502. The outer wall of the bottle cap body 501 is fixedly connected with the inner wall of the anti-slip ring 503. The anti-slip ring 503 is rotated, and the rotation of the anti-slip ring 503 drives the bottle cap body 501 to be threadedly connected with the sealing cover body 301 through threads. The second sealing ring 502 on the inner top of the bottle cap body 501 abuts against the top of the sealing cover body 301 to play a sealing role. Through the two blocking blocks 303, when the bottle cap 5 is rotated, the sealing cover 3 will not rotate.
[0028] The use method and advantages of the utility model: When the food packaging plastic bottle made of degradable material is in operation, the working process is as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, by rotating the handle 202 to a vertical direction, the entire plastic bottle can be carried by hand, and the bottle can be hung on a hook through the hanging ring 203 for easy carrying and transportation. The bottle body 101 is loaded with food. After the food is loaded, the sealing cover body 301 is rotated, and the sealing cover body 301 is threadedly connected to the bottle mouth 102 through threads. The first sealing ring 302 at the inner top of the sealing cover body 301 abuts against the top of the bottle mouth 102 to play a sealing role. The anti-skid ring 503 is rotated, and the two blocks 303 can prevent the sealing cover 3 from rotating when the bottle cap 5 is rotated. The anti-skid ring 503 rotates to drive the bottle cap body 501 to be threadedly connected to the sealing cover body 301 through threads, and the inner top of the bottle cap body 501 is screwed to the bottle cap body 501. The second sealing ring 502 is in contact with the top of the sealing cover body 301 to play a sealing role. The double-layer sealing effect can preserve food for a long time. By rotating the anti-skid ring 503, the anti-skid ring 503 rotates and drives the bottle cap body 501 to rotate. The inner top wall of the bottle cap body 501 abuts against the top of the sealing limit block 401, pressing the sealing limit block 401 downward, and the sealing limit block 401 is pressed downward to drive the limit column 403 to be pressed downward, and the limit column 403 is pressed downward to drive the drying box body 404 to be pressed downward. The pressing of the drying box body 404 can leave a gap so that the desiccant in the drying box body 404 can dry the food. At the same time, the drying box body 404 also effectively reduces the risk of food contamination caused by desiccant damage.
