[0002] Disposable tableware has brought great convenience to people's daily lives and is still in large quantities. Although some people have pointed out that it is a huge waste of resources, the application of new materials and new technologies will provide new solutions to the resource and environmental problems caused by its use. Therefore, these disposable items will continue to exist in our lives for a long time. In some special occasions, such as hospitals and epidemic areas, a large number of such disposable items are needed to avoid the risk of infection. In the current use of disposable items, most businesses can dispose of them in accordance with regulations after use, but in actual use, some illegal vendors use used lunch boxes to provide them to consumers in the catering industry for profit. On the one hand, these disposable items are designed for single use and do not have the basis for multiple use. On the other hand, these disposable items will carry a large number of pathogens after use, which will bring great risks to consumers' health when used again, and there are great safety hazards.

[0016] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0017] like Figure 1 and Figure 3 The figure shows a degradable bowl cover that avoids reuse, comprising a bowl body 1 made of degradable material and a cover body 2 used in conjunction with the bowl body 1, the outer wall of the bowl body 1 is attached with a label sticker 3 made of water-absorbing material, the label sticker 3 is printed with a logo layer 4, the outer surface of the label sticker is coated with a wax powder layer 5 with a melting point of 60 to 95 degrees Celsius, and the wax powder layer 5 covers the logo layer 4.

[0018] In the present embodiment, the identification layer 4 is a text printing layer with the word "used" printed on it. When the bowl cover is in an unused state, the wax powder layer 5 is composed of opaque wax powder, and the text printing layer cannot be seen, proving that the bowl cover is in an unused state; when the bowl cover is used, the high temperature of the food is transmitted to the wax powder layer 5 by the bowl body 1. The wax powder layer 5 is melted by the heat and absorbed by the label sticker 3 to become transparent, and the text printing layer is revealed. Consumers can clearly see the word "used", and the wax powder is absorbed by the label sticker 3 after melting and cannot be restored. Consumers can judge whether the bowl cover is used for the first time based on this, thereby avoiding reusing the heated bowl cover. It has the advantages of simple structure, low cost and high reliability, and is highly practical.

[0019] In this embodiment, the identification layer 4 can also be a color coating. Taking red as an example, white is marked next to the identification layer 4 for unused and red is marked for used. In actual application, the wax powder layer 5 is white powder, proving that the box cover is unused. When the wax powder layer 5 is melted by heat and absorbed by the label sticker 3 to become a thin transparent layer, the red coating appears to achieve the technical effect of marking as used.

[0020] In this embodiment, the logo layer 4 is attached with a waterproof layer 6, and the logo layer 4 and the wax powder layer 5 are embedded between the label paper and the waterproof layer 6 to prevent the wax powder layer 5 from being rubbed off during storage or transportation and affecting the function, with high reliability.

[0021] In the present embodiment, the middle portion of the cover body 2 is recessed downward to form a heat-insulating support body 7, and the outer surface of the heat-insulating support body 7 is provided with the label sticker 3. Through the label sticker 3 on the cover body 2, consumers can immediately observe whether the outer cover has been used. In actual use, the cover body 2 is turned over and placed on the table. When the bowl body 1 is placed on the table, due to the design of the heat-insulating support body 7, an insulating hollow layer can be formed between the bottom surface of the bowl body 1 and the table top, thereby effectively preventing the actual object from overheating and scalding the table top, and having high safety.
