Yes, if the sign on the bucket is missing, you need to buy another sign. Trademark is an important symbol of products, which can help consumers identify the source and quality of products. If the trademark disappears, consumers may not be sure of the authenticity and quality of the product, thus reducing the credibility and market competitiveness of the product.

In this case, it is suggested to contact the barrel manufacturer or trademark agency to buy the trademark again. If the bucket manufacturer has stopped production or can't be contacted, you can consider designing and making the trademark yourself, but you need to ensure the legitimacy of the trademark and meet the requirements of relevant laws and regulations. At the same time, we also need to pay attention to the quality of trademarks and anti-counterfeiting measures to ensure that consumers can correctly distinguish the source and quality of products.
