1. A container blank comprising:
a paperboard shell layer comprising two transverse edges on opposing sides of a central axis, a shell bottom edge extending between said transverse edges orthogonal to said central axis, and a shell top edge opposite said shell bottom edge and extending between said transverse edges;
wherein said shell layer comprises:
a body portion extending from said shell bottom edge to a lower line of limitation;
a predetermined removeable portion extending from said lower line of limitation to an upper line of limitation; and
a cap portion extending from said upper line of limitation to said shell top edge; and
a paperboard core layer, wherein when said core layer is in facing relationship with said shell layer said core layer extends from below said lower line of limitation to a core rim above said upper line of limitation;
wherein when said core layer is in facing relationship with said shell layer said core rim is located at a rim distance from said shell bottom edge as measured parallel to said central axis and said rim distance is a function of distance from said central axis;
wherein when said core layer is in facing relationship with said shell layer said core rim has a rim distance global maxima and a rim distance global minima relative to said shell bottom edge; and
wherein said core rim is sinusoidal.
