Paper towel dispenser
US-7338007-B2Abstract
The present invention relates to a paper towel dispenser in which the towels are provided from a reel enrolled around a central nucleus. The nucleus has at both ends guiding devices of the reel along both lateral descending grooves; thus, the reel can slide in a descending direction until the periphery of said reel is supported by a gyratory stop. When the external diameter of the reel decreases it continues sliding along the grooves until the guiding means enter into unlocking devices of the reels making the reel descend until the guiding devices push downwards a posterior end of a lever, the other end of said lever having indicating devices and threading devices of a new reel. Said posterior end ejects the nucleus when it is empty towards a cavity in the inferior part of the dispenser in order to be taken away afterwards.
