Problems solved by technology

Another issue that can arise with container lip design is that the inner edge of the lip (which is usually formed by a trimming operation) can present a sharp edge.
This sharp edge can be uncomfortable and / or dangerous to the consumer, whether they are drinking directly from the container, or grasping product located within the container.

Related Art [0005] Plastic containers, such as polyolefin or PET containers, may be used for packaging food, dairy, and other drinkable products. Such containers can be sealed at the opening in the neck using a conventional closure such as a screw-on or push-on lid. Additionally or alternatively, these containers can be thermosealed with a suitable lid, for example, a foil lid. A thermosealed lid is designed to be pulled off to allow access to the contents of the container. Once opened, the contents can be, for example, ...
