Abstract
A dispenser for length material comprises a first resiliently biased locking roller and a second locking roller defining a nip therebetween for the passage of length material to be dispensed, the second roller being carried on a frame which upon appropriate movement causes the second roller to move into a locking position in relation to the first locking roller to clamp the length material to prevent unreeling or return of the free end thereto once appropriate cutting of a portion of the length material has been effected.
Claims23
A dispenser for a length material comprising:
- a rotatable first locking member defining a first axis and being radially biased by a biasing member;
- a second locking member defining a second axis substantially parallel to said first axis and spaced therefrom;
- a nip defined between the first and second locking members for receiving therethough in use at least an end portion of the length material;
- and
- a movable frame circumjacent the first locking member for selective contact therewith, the frame carrying said second locking member and being adapted to use to effect relative movement between a locked configuration in which in use the length material is clamped in the nip by the biased first locking member acting against the second locking member and an unlocked configuration in which the length material is free to move through the nip.

A dispenser system comprising:
- a roll of length material having at least an end portion and a dispenser mounted on a portion of the roll of length material, the dispenser comprising:
- a rotatable first locking member defining a first axis and being radially biased towards the portion of the roll of length material by a biasing member;
- a second locking member defining a second axis substantially parallel to said first axis and spaced therefrom;
- a nip defined between the first and second locking members for receiving therethough in use at least an end portion of the length material;
- and
- a movable frame circumjacent the first locking member for selective contact therewith, the frame carrying said second locking member and being adapted to use to effect relative movement between a locked configuration in which in use the length material is clamped in the nip by the biased first locking member acting against the second locking member and an unlocked configuration in which the length material is free to move through the nip.
