The invention relates to pressed paperboard containers, such as disposable paper plates and bowls, having increased strength and rigidity, and the processes used to form such containers by the formation of non-radial pleats at outer regions of the container. The invention also provides pleats about the outer periphery that are non-linear along the length of the pleat. Such non-radial and non-linear pleats are formed by forming non-radial and non-linear scores in a blank of paperboard converted into the container geometry.

The present invention generally provides an insulating vessel for beverages. The vessel has an outsert and a insert. The insert is positioned within the cavity of the outsert. In one embodiment the insert has a plurality of insulating members that are spaced from an inner surface of the outsert to define a series of air gaps between an outer surface of the insulating members and the inner surface of the outsert. In another embodiment, the insert and outsert have generally conical side walls with substantially the same taper angle so as to be in a friction lock relationship with one another.

Drinking cup lids are especially adapted and configured to afford some measure of protection to the game piece from beverage seepage through a straw opening. Preferably, the cup lid is configured so that a game piece is spaced above the straw opening co-located within a recessed well of the lid thereby allowing beverage seepage to remain physically separated from the game piece. Access to the beverage within the cup is facilitated by providing a cross-cut straw aperture in the game piece which is in substantial alignment to the straw opening formed in the lid. A beveled segment of a raised plateau on which the game piece is affixed allows a tab associated with the game piece to be more easily grasped and removed by a customer to reveal the printed text/indicia of the game piece.

Domed lids for beverage cups include an arcuately convex lower side wall section, and an arcuately convex upper side wall section protruding upwardly from the lower side wall section. Most preferably, each of these upper and lower side wall section is in the form of a respective spherical surface, with the upper side wall section having a lesser radius of curvature as compared to the radius of curvature of the lower side wall section. In particularly preferred forms, cup lids are provided having an arcuately convex lower side wall section establishing a circular base skirt adapted to being attached to an upper lip of a cup; and an arcuately convex upper side wall section. The upper side wall section is joined at a lower edge region thereof to the lower side wall section by means of an annular concavity, and protrudes coaxially upwardly from the lower side wall section to an annular apical edge region. The upper side wall section includes a reentrant well recessed below the apical edge region and defines an opening in a terminal surface thereof.
