ABSTRACT:
Described is a device designed to dispense tissue paper or cloth web by a self-locking dispenser system. The dispenser system consists of a release mechanism which is activated by hands-on mechanical or hands-free electo-mechanical means. The gear train in the dispenser mechanism is connected to the tissue or towel roll axle and thus regulates the motion of the roll. The dispensing system, in activated mode, allows free passage of the tissue or towel web out of the dispenser through an opening in the dispenser housing but, in the released position, itself locks up the tissue or towel web in this opening with a tight prong device thus prohibiting the web from further movement. This is accomplished without locking up the roll axle. The whole system including the roll is installed inside an air-tight housing which allows usage of dry as well as moistened tissue or towel. The dispenser housing is provided with a movable, transparent front cover to provide visibility to the extent of roll usuage. Finally, the dispenser housing has the optional means to provide manual dispensing of the web free from the self locking mechanism.
