Abstract

The present disclosure relates to a dispenser (10) for use with rolls of film material, particularly coreless rolls. The mandrels (40, 42, 40') of the dispenser can move between a retracted position wherein the dispenser has a reduced diameter, such as for when the dispenser is being inserted into a roll of film, and an increased diameter, such as for when the film is being dispensed from the dispenser. The mandrels (40, 42) have sections which are joined by various spring configurations (60, 62, 64) and are formed as being axially slidable with respect to a central shaft (12) with lug elements (14). As the mandrel is slid along the central shaft, the lug elements deflect the spring configurations outwardly so as move the mandrels radially outwardly and increase the radius of the dispenser.
