ABSTRACT:
A system for dispensing coreless rolls of product. The system includes: (1) a rotary dispenser including a frame, a mounting mechanism and a pair of cooperating plungers, each plunger including: a base, the base being fixed to the frame; a distal end, the distal end having a radius of curvature; and a central shaft, the central shaft connecting the base and the distal end and providing sufficient length so the plunger has a length at least as great as its widest dimension so the plunger is adapted to penetrate a mounting hole defined at an end of a careless roll product, and (2) a coreless roll of product that is self-supporting in the rotary dispenser, the careless roll including: a rolled web of product that is wound substantially throughout its diameter about a winding axis into a cylinder having first and second flat ends; and at least one flat end defining a mounting hole at substantially the center of the winding axis of the coreless roll, the mounting hole having a depth and having sides generally perpendicular to the end of the roll, the sides being separated by a distance that is less than the depth of the hole. The mounting hole of the coreless roll is adapted to receive a plunger from a rotary dispenser such that radial displacement of the careless roll with respect to the frame is prevented during use.
