The key lies in the patented packaging box of the tea packaging shop you bought.
If this box is not a special box for other brands of tea, it is not necessarily infringement, just like you bought a porcelain jar with a patent for design in a porcelain factory and sold it with tea, it is not infringement, and it is not very strict to say that exhaustion avoids infringement;
If this box is a special box for a brand of tea, and this box shop is their special supplier, if you use it again, it may confuse consumers and cause infringement on them.
Pay special attention to whether there are trademarks (names, logos, etc.). ) other tea brands.
