The name of the patent application is "cosmetic packaging box", can it represent the product patent?

Not correct. The packaging box is the patent of the packaging box, and the product itself is not the packaging box. Whether your product is imported or locally produced, if the product has a patent, it is usually in the formula or production technology. What does it mean to represent the product itself? Just to confuse consumers, how easy it is to apply for a package design. Marking the patent number reminds people of the product itself. These are two different things, but he did get the patent (for the box), and it is not illegal to print it on the box. If he wants to express that the patent represents the technology of the product itself, you ask him if the product formula has a patent. If it is imported, is the formula patented abroad? By the way, let's see if his patent number is just a simple number, or did you write down the patent name? If only a number is marked, and the marking is not standardized, there should be the words "China Design Patent". If it is mislabeled, it may be considered as a patent.
