METHODS, CONTAINERS, AND SYSTEMS TO INCREASE SIDEWALL STRENGTH

摘要

Method to increase strength of a rolled rim container having a sidewall defining a perimeter, a base at a first end of the sidewall, and an opening defined at a second end of the sidewall opposite the base. A portion of the sidewall at the second end is provided with or can be rolled to form a rolled rim. The rolled rim defines an interface along the perimeter between an outer surface of the sidewall and an exposed surface of the rolled rim. A bead material is applied along the interface between the exposed surface of the rolled rim and the outer surface of the sidewall. The bead material is cured to form a bead between the exposed surface of the rolled rim and the outer surface of the sidewall. Rolled rim containers and systems for forming the same are also disclosed.

1. A method to increase strength of a rolled rim container, comprising:
providing a container having a sidewall defining a perimeter, a base at a first end of the sidewall, and an opening defined at a second end of the sidewall opposite the base; rolling a portion of the sidewall at the second end to form a rolled rim container having a rolled rim, the rolled rim defining an interface along the perimeter between an outer surface of the sidewall and an exposed surface of the rolled rim; applying a bead material along at least a portion of the outer surface of the sidewall; and curing the bead material to form a bead between the exposed surface of the rolled rim and the outer surface of the sidewall.
