Method of forming a container having a rolled rim, including providing a thermoformable sheet, and thermoforming the sheet to form a hollow body. The hollow body has an open first end and an opposite closed second end with a sidewall extending between the first end and the second end, and a rim structure formed at the first end of the hollow body. The rim structure includes an inner wall portion, a flange, and a skirt. The method further includes coining an upper section of the inner wall portion of the rim to form a controlled inner diameter, and rolling the rim structure to form a rigid rolled rim along an outer diameter of the open first end of the hollow body, the skirt extending toward the sidewall after being rolled.

The disclosure relates to forming shaped thermoplastic articles having smooth peripheries. Many thermoplastic articles have sharp edges formed upon molding or cutting the article from a feedstock sheet. Such sharp edges can damage thin plastic films or flesh which they contact, and smoothing the edges is desirable. Described herein are methods of forming a smooth periphery for such sharp-edged articles by rolling over the sharp edge. The smoothing operation is performed by forming a deflectable flange including a bend region separated from the potentially sharp peripheral edge by a spacer, deflecting a portion of the deflectable flange, and softening at least one bent portion of the deflectable flange to yield a smooth periphery upon cooling. The deflection can include curling the spacer at or near the peripheral edge. The methods can be performed incrementally and/or in a reciprocating fashion.

A drink cup includes a body formed to include an interior fluid-storage region and a brim. The brim is coupled to the body to surround an opening into the interior fluid-storage region. The brim is formed by a brim-forming machine.

The invention relates to a can containing a liquid and/or a gaseous medium which has positive pressure or develops such during transport or storage, wherein the cylindrical can shell of the can consists mainly of paper or cardboard material and is closed at the bottom with a bottom element and at the top with a cover element, wherein the can withstands an internal pressure of at least 5 bar, wherein the innermost layer of the can shell consists of a straight-wound barrier layer having a longitudinally extending folded seam, wherein the barrier layer is a prefabricated laminate made of an inner diffusion-tight barrier film or an inner diffusion-tight barrier laminate and an outer kraft paper layer.

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.
