Cup made of paper material having a fillable interior space formed by a shell and a base. The base via a skirt at the lower end of the interior space is fastened in a substantially liquid-tight manner to the shell, and a lower periphery of the skirt forms a footprint for the cup. The cup has an external shell composed of a planar blank of paper or paper-like material. Longitudinal edges of the blank are connected to one another in an overlap region so that the external shell forms a sleeve. The external shell, has a frustoconical shape having a first cone angle and, except for the overlap region, from the predefined spacing to the lower end is configured in a single ply. The shell, from the predefined spacing to the lower end, at least in portions tapers more heavily than in the region above the predefined spacing.

A paper cup and a method of forming the same. The paper cup may include a sidewall and a floor portion that collectively define a cavity. In one aspect, the paper cup may include a rim that is coated with a rigid shell that encapsulates the rim. In another aspect, a void defined by a rim of the paper cup may be filled with a rigid filler material, and the rigid filler material may be one that expands upon application of heat thereto. In yet another aspect, the paper cup may include a separate rim component that is attached to the sidewall. The separate rim component may be formed from molded pulp fibers, and it may include a flange portion that is attached to the sidewall and a rim portion that protrudes from the sidewall.

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 pack of cardboard with a base, a fixed lid and an encircling side wall, has a reclosable removal opening provided in the lid. The removal opening may be covered by a movably arranged cardboard layer. More than one cardboard layer may be provided for covering the removal opening.
