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.
