Abstract: A product roll includes, in its most preferred embodiment, a cylindrical core defining a core central passage for receipt of a dispenser spindle and including a core outer surface and a core inner surface, a roll of product coaxially wound around and attached to the core outer surface, and a rotation retardant attached to the core inner surface for retarding rotation of the product roll with respect to the dispenser spindle. Alternate embodiments include a cylindrical core with an adhesive filler as one component of the core mass, a multi-layered core having an inner layer defining friction-increasing projections and indentations, and a core insert with a strong outer adhesive for relative stationary engagement with the core and a weak inner adhesive for impeding rotation of the core and core insert assembly.

Abstract: A rotation-retarded product roll which product roll includes, in its most preferred embodiment, a cylindrical core defining a core central passage for receipt of a dispenser spindle and including a core outer surface and a core inner surface, a roll of product coaxially wound around and attached to the core outer surface, and a rotation retardant attached to the core inner surface for retarding rotation of the product roll with respect to the dispenser spindle. In an alternate embodiment of the present invention, an alternately formed core inner surface retards rotation of the product roll with respect to the dispenser spindle.
