Refill device for a dispensing system

A refill device for a dispensing system comprising:

• a material web wound to form a roll;
• a support bar having a central region and two bearing journals each forming an end part of said support bar respectively projecting on both sides from said roll, said central region having a substantially cylindrical outer contour;
• at least one of said two bearing journals having a mating surface, said mating surface being configured to not be a rotation surface;
• and
• said roll of said material web being rotatably disposed on said central region of said support bar,
• wherein a winding of said material web encloses said central region of said support bar to cause a breakaway torque of at most 0.2 Nm to be introduced for drawing off the material web, and
• wherein a follow-on torque for unwinding the material web effective after overcoming the breakaway torque lies between 0.0025 Nm and 0.1 Nm.
