Problems solved by technology
[0003] Current cups are generally all made of plastic, which are very difficult to degrade after use. If they are discarded, they will cause great harm and pollution to environmental sanitation, and the cup holders in the prior art are also made of non-degradable materials. When these appliances are scrapped, it is very difficult to dispose of the material left behind

Embodiment
[0028] see Figure 1-Figure 4 , a fully degradable PLA round cup and tray rack, including a cup body 1 and a cup holder 2, the upper end of the cup holder 2 is provided with a cup hole 3, and the lower end of the cup hole 3 is fixedly connected with a cup holder 4, the cup Both the body 1 and the cup holder 4 are made by removing the moisture in the raw materials at one time by a no-bake injection molding machine. There are vent holes 5 at the bottom, four cup holes 3 on the upper end of the cup holder 2, and four cup holders 4 corresponding to the lower ends of the cup holes 3 are also fixedly connected to facilitate the even placement of the cup body 1. The inside of the cup holder 4 is fixedly connected with a spacer 6, and the spacer 6 is provided with four equiangular angles. A certain space is formed between the cup holders 4, which can dissipate heat quickly. The upper end of the cup holder 2 is provided with anti-slip stripes 7, and the anti-slip stripes 7 are provide...

The invention discloses a full-degradable PLA circular cup and a tray rack, which comprise a cup body and a cup holder, a cup hole is arranged on the upper end of the cup holder, a cup base is fixedly connected to the lower end of the cup hole, the cup body and the cup base are both made by removing water in raw materials at a time through a baking-free injection molding machine, a vent hole is arranged at the bottom of the cup base, a partition block is fixedly connected to the interior of the cup base, and anti-skid stripes are arranged at the upper end of the cup holder. The full-degradable PLA circular cup and the tray rack are made of polylactic acid material, can be degraded and does not affect the environment, the unique baking-free injection molding machine is adopted for removing water in the raw materials at a time, the surface of the product is smoother, forming is stable, the production period is short, and the product can be produced in batches; after use, the full-degradable PLA circular cup and the tray rack are made of the degradable polylactic acid material, the material can be subjected to innocent treatment after being scrapped in the later period, the environment is protected, colored pollution is avoided, the material used by the product can also be made into other products, and contributions are made to the environmental protection cause.
Description
technical field [0001] The invention relates to the field of daily necessities manufacturing, and more specifically relates to a fully degradable PLA round cup and tray frame. Background technique [0002] Polylactic acid is a new type of biodegradable material made from starch raw materials proposed by renewable plant resources such as corn. The starch raw material is saccharified to obtain glucose, and then fermented by glucose and certain strains to produce high-purity lactic acid, and then synthesize polylactic acid with a certain molecular weight by chemical synthesis. It has good biodegradability, can be completely degraded by microorganisms in nature after use, and finally produces carbon dioxide and water without polluting the environment; polylactic acid has good thermal stability, processing temperature is 170-230 ℃, and has good solvent resistance , can be processed in a variety of ways, such as extrusion, spinning, biaxial stretching, injection blow molding, pro...
