Abstract A nestable two-piece cup or container the sidewall portion of which is formed from a double-ended, crescent-shaped blank of paperboard or other sheet-like material by rolling it into a frusto-conical configuration with the edges of the blank overlapping one another in face to face contact and being glued to one another to form a side seam of double thickness, one of the edges of the blank being scored or perforated or otherwise deformed to form a tab which is manually removable from, or foldable out of, face to face contact with the other edge of the blank by the user of the cup to give a visible indication that the cup has been used and to thereby discourage the vendor from attempting to refill a previously used cup. The first user of the cup may be motivated to so deform the cup by placing a number, symbol or other graphic message on the underside of the tab or on the sidewall of the blank in the region normally covered by the tab, of a portion of such cups, and by advising the users of such cups that prizes will be awarded to those whose cups bear such graphic message.
A nestable, two-piece container comprising, in combination: a tubular sidewall member of generally, frusto-conical outer configuration formed from a crescent-shaped blank of paperboard, the blank being folded to form such member and having opposed straight edge portions of the blank overlapping one another and secured to one another in face to face relationship; the upper open end of said sidewall member being rolled back upon itself to form a rim; and a bottom member secured to the bottom of the sidewall member and adapted to close the bottom of suCh container, said sidewall member having a tab formed integrally therewith in an edge portion of the blank from which said sidewall member is formed, said tab being defined by deforming said blank along an irregular line extending from a first point adjacent said edge and spaced below said rim into said blank and back to a second point which is adjacent said edge and between said first point and said bottom member, said tab being manually removable from face to face relationship with the adjacent portion of the other edge portion.
