Abstract
Means for shaping a stack of discrete interleaved sheets to improve the pop-up type dispensing thereof from a package containing the stack and having a dispensing orifice thereabove. The sheets are characterized by such stiffness that, when arranged in a conventional interleaved stack wherein the interleaved sheet portions are substantially planar and horizontal, during the removal of a given sheet from the stack through the package dispensing orifice the portion of the next succeeding sheet overlying a portion of the sheet being removed tends near its adjacent folded edge to lift away from the sheet being removed, permitting the sheet being removed to slip out from under the succeeding sheet, resulting in failure of the succeeding sheet to achieve its pop-up position through the dispensing orifice. The means to shape the stack comprises support means for the stack so configured as to cause the central portion of the stack to be depressed so that the interleaved portions of the sheets are non-planar and are concave in at least one plane in which the vertical axis of the package lies.
