Claim:
A container comprising: a bottom; and a cylindrical or conical sidewall, wherein the upper portion of said sidewall is formed with a set of creases defining a foldable closure, said creases including three sets of creases; a first set of mountain creases including curved arcs proceeding around the circumference of said sidewall; a second set of mountain creases that extend from vertices of said first set upward to the upper edge of said sidewall; a third set of valley creases extended from said vertices of said first set upward to the upper edge of said sidewall, each disposed at an angle relative to an adjacent mountain crease from said second set; said mountain and valley creases dividing the upper portion into a series of geometric panels; said creases formed so that when all creases are folded, the panels form a barrier above the contents of said container, and each of said valley folds cross in the center of said closure, and said valley folds extend substantially beyond the center of said closure.
