Abstract (en)
A paperboard container and a method and apparatus for producing it are disclosed.

The second region preferably comprises a ledge or shoulder formed in the side wall of the container and spaced from both the top and the bottom of the side wall. A top piece preferably rests on the ledge or shoulder, and serves as a lid.
