Is there a patent in tetra pak?

Enter the patent retrieval analysis platform in official website, China National Intellectual Property Administration, and enter Tetra Pak for retrieval under the conventional retrieval items. There are many results. I don't know which company you are talking about.

In addition, the technical content of design patents is relatively low. In order to reduce the workload and shorten the application time, the examination is not very strict, so there will be some similar patents.
