Abstract
A film dispenser for use in unwinding film from coreless film rolls. A first dispenser member is selectively matable with a second dispenser member. The first and second dispenser members can be mated together in at least two angular positions. The position of a radially outward facing surface of the dispenser can be adjusted based on the angular position of the dispenser members so that the dispenser can firmly engage and support film rolls of varying internal dimensions. Each of the dispenser members can have a radially extending support wall. The support walls define complementary interlocking formations. When the dispenser members are mated together, the complementary interlocking formations engage one another to form a rigid connection between the dispenser members. The engaged support walls radially support a central region of the film roll.
