ABSTRACT:
A system and method for dispensing roll material is described that substantially prevents toilet paper runaway and is useful in reducing irritation caused by using dry toilet paper. In one embodiment, the dispenser has a structure that has a thin, but strong curved, rigid arm with a tooth that is biased to engage the toilet paper roll in such a manner that it will only permit the roll to turn only in one direction. If the roll is attempted to be turned in the opposite direction, the tooth, which is disposed toward the roll, will engage the roll and prevent rotation in the second direction without substantially damaging the toilet paper on the roll. In a second embodiment, the toilet paper dispenser will dispense a predetermined amount of toilet paper into a receiver that has a sufficient size that it will fold over onto itself a predetermined number of times. Once the predetermined amount of toilet paper is disposed in the receiver, the system will dispense a measured amount of lotion, cream, or other type of cleansing liquid that will provide not only cleansing of the desired tissue area but also act as a lubricant for the toilet paper so that it will not irritate the tissue.
