SYSTEM FOR DISPENSING CORELESS ROLLS OF PRODUCT

摘要

A system for dispensing coreless rolls of product (12, 710). The system includes: (1) a rotary dispenser (10, 40, 100) including a frame (14, 42, 102), a mounting means, and a pair of cooperating plungers (28, 52, 114), each plunger (28, 52, 114) 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 (28, 52, 114) has a length at least as great as its widest dimension so the plunger (28, 52, 114) is adapted to penetrate a mounting hole (800) defined at an end of a coreless roll product (12, 710), and (2) a coreless roll (12, 710) of product that is self-supporting in the rotary dispenser (10), the coreless roll (12) including: a rolled web of product that is wound substantially throughout its diameter about a winding axis (806, 906) into a cylinder having first and second flat ends (712); and at least one flat end (712) defining a mounting hole (800) at substantially the center of the winding axis (806, 906) of the coreless roll (12, 710), the mounting hole (800) having a depth and having side (702) generally perpendicular to the end (712) of the roll (12, 710), the sides (702) being separated by a distance that is less than the depth of the hole (800). The mounting hole (80) of the coreless roll (12, 710) is adapted to receive a plunger (28, 52, 114) from a rotary dispenser (10) such that radial displacement of the coreless roll (12, 710) with respect to the frame (14, 42, 102) is prevented during use.
