Abstract
A plastic container is provided having a sidewall, a downwardly extending upper lip, and a perforated line defined at a top edge of the container where the lip and sidewall are joined. The sidewall and lip may be formed from a container body constructed of a single sheet of material that is wrapped such that marginal edge portions of the blank are brought together in overlapping fashion to form a side seam. When the sidewall and lip are formed from such a blank of material, the perforated line is formed a specified distance below a top edge of such blank. The perforated line reduces the amount of force, heat and lubricant required in order to form (e.g., curl, roll, fold or bend) the upper lip of the container. The slits of the perforated line may extend across a width of the blank in either a uniform or variable fashion.
