Abstract

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.
