Abstract: Containers and a method for forming such containers having larger brims with reduced brim curl defects is disclosed including providing a plurality of container blanks for forming containers, forming a plurality of container shells from the plurality of blanks, accumulating the plurality of container shells at an accumulation station, subjecting at least an upper periphery of the shells to a humid atmosphere to precondition the shells with the atmosphere preferably including steam, successively removing the shells from the accumulator and subsequently forming a brim curl about an upper periphery of the shell with the shells being subject to the humid atmosphere for a predetermined time period sufficient to form defect-free brim curls by extending the forming strain limits of the paperboard material. This method being carried out by using an accumulator for accumulating the container shells for further processing.

Abstract: A container formed of paper material is disclosed including a substantially cylindrical body having an upper, a lower, a bottom integrally formed with the cylindrical body and closing the lower end, and a brim integrally formed on the upper end of the cylindrical body, the paper material being oriented such that the machine direction of the paper material is aligned with the circumferential direction of the container. The container being formed by providing a paper blank having a machine direction and a cross machine direction, forming the paper blank into a substantially cylindrical body having first and second open ends with the machine direction of the paper blank being aligned substantially with the circumferential direction of the body, closing one of the open ends to form a bottom of the container and forming a brim about the other of the open ends.
