  • Patent number: 5390820
    Abstract: An elevating dispenser for flexible sheet materials and more particularly for interleafed cosmetology end papers. The flexible sheets are contained in a carton with a dispensing aperture in the top wall. The dispensing aperture has flaps to retain the end of successively drawn sheets above the aperture for ease of withdrawal. The stack of sheets rests within the carton on an elevating platform which is flexibly attached on two opposing sides to the base of the adjacent side walls of the carton by flexibly folded extension panels which allow upward urging of the elevating platform. This facilitates the removal of sheets from a stack of diminishing thickness as the sheets are removed, one at a time. The elevating platform is retained in progressively upward positions by friction between its edges and the inside surfaces of the carton walls and by tabs in the end walls which are pressed into the chamber of the carton beneath the elevating platform.
