Abstract
Refill for a dispenser, with a material web wound to form a roll and at least one substantially axially adjustable bearing journal. The at least one substantially axially adjustable bearing journal is adjustable substantially axially outwards away from the roll starting from a defined inner end position in which it protrudes axially beyond the roll. A bearing unit for such a refill, and a dispenser for housing the refill and dispensing the material web are also provided.
Claims35
A refill for a dispenser, the refill comprising:
- a material web wound to form a roll;
- a bearing unit having an axial support disposed in said material web wound to form said roll;
- at least one bearing journal mounted so as to be axially displaceable with respect to said axial support, wherein said at least one bearing journal is mounted so as to be rotatable about its longitudinal axis with respect to said axial support and wherein said at least one bearing journal has a shape without circular symmetry with respect to the longitudinal axis of said at least one bearing journal at least in areas;
- said at least one bearing journal being mounted so as to be displaceable between a defined inner end position and a defined outer end position and to protrude axially beyond said roll when in both the inner and outer end positions;
- and
- stops that define the defined inner and outer end positions of said at least one bearing journal.

A bearing unit for a refill formed from a material web wound to form a roll, the bearing unit comprising:
- an axial support for inserting into the material web;
- at least one bearing journal mounted so as to be axially displaceable with respect to said axial support, wherein said at least one bearing journal is mounted so as to be rotatable about its longitudinal axis with respect to said axial support and wherein said at least one bearing journal has a shape without circular symmetry with respect to the longitudinal axis of said at least one bearing journal at least in areas;
- said axial support having a counter stop;
- and
- at least one stop attached to or formed on said at least one bearing journal, said at least one stop strikes said counter-stop on said axial support, whereby an inner and outer end position of said at least one bearing journal are defined.

A device, comprising:
- a refill for a dispenser, said refill containing a material web wound to form a roll;
- a bearing unit having an axial support disposed in said material web wound to form said roll and at least one bearing journal mounted so as to be axially displaceable with respect to said axial support, wherein said at least one bearing journal is mounted so as to be rotatable about its longitudinal axis with respect to said axial support and wherein said at least one bearing journal has a shape without circular symmetry with respect to the the longitudinal axis of the at least one bearing journal at least in areas, wherein when said at least one bearing journal is in a transportation position said at least one bearing journal lies inside said roll and does not protrude at sides of said roll;
- said axial support having a counter stop;
- and
- at least one stop attached to or formed on said at least one bearing journal, said at least one stop strikes said counter-stop on said axial support, whereby an inner and outer end position of said at least one bearing journal are defined.
