Methods and apparatus may permit the storage of flexible sheet materials in a space-efficient manner and may provide a continuous point-of-use dispensing capability of such sheet materials at such stored location. Serially joined sheet materials may be separated from one another at sheet materials separation zones utilizing interference tabs having yieldable configurations, intra-planar configurations, trans-axial configurations, movement resistive configurations, and projective configurations. Such interference tab configurations may permit the simplified design and construction of a sheet materials dispensation apparatus, and multiple flexible sheet materials may be serially joined for use with such configurations. A substantially rigid enclosure for storing such serially joined sheet materials and incorporating an interference tab having one or more of such configurations may be dimensioned to dispense sheet materials from within an open-ended receptacle, for example a refuse container.
