Abstract

A dispenser assembly (1) for dispensing a sheet (2) from a roll of sheet material (3), the roll of sheet material (3) defining a cavity (4) extending longitudinally, the dispenser assembly (1) comprises: a roll holder (5) for removably holding the roll of sheet material (3), the roll of sheet material (3) being free to rotate relatively to the roll holder (5); a base (6) for supporting the roll holder (5) and for coupling the dispenser assembly (1) with an environment structure (7); and - a pair of coupling elements (8) comprising a first element (9) coupled to the roll of sheet material (3) and a second element (10) integral to the roll holder (5), the first element (9) being coupled in a free to rotate and removable manner relatively to the second element (10) by magnetic coupling. The first element (9) comprises a longitudinally extending engaging portion (11) which is arranged to at least partially engage with an end portion (12) of the cavity (4) of the roll of sheet material (3) so that the first element (9) is fixedly secured to the roll of sheet material (3).

Description

technical field [0001] One aspect of the invention relates to a dispenser assembly. The invention further relates to a roll of sheet material suitable for dispensing by the dispenser assembly of the invention. Such dispenser assemblies are particularly, but not exclusively, useful for dispensing rolls of paper towels.
