Publication number: 20230037335Abstract: The invention relates to hygienic paper in web form for moist applications that preferably consists of mutually contiguous sheets that are connected to one another via a tear-off perforation, wherein the hygienic paper consists of a cellulose mass with embedded reinforcement fibers and the reinforcement fibers have an increased tear strength on an initial moistening and at least partly lose their tear strength after an extended moistening, whereby the sheets disintegrate into smaller pieces over the course of the time after the moistening, at the latest in the sewer system. The invention further relates to hygienic paper comprising individual sheets, wherein the sheets are each provided with at least one disintegration perforation that provides a disintegration of the sheets into smaller pieces over the course of the time after a moistening, at the latest in a sewer system.Type: ApplicationFiled: January 12, 2021Publication date: February 9, 2023Inventor: Werner Kaufmann

Patent number: 7185841Abstract: A dispenser for hygiene paper is proposed which makes available dry toilet paper and dispenses moistened hygiene paper. For this purpose, the dispenser contains a housing, a roll holder for the hygiene paper, a unit for the moistening with a liquid container, a moistening roll and at least one liquid tank which communicate with one another and a unit for the dispensing with a transport roll for the hygiene paper which is in contact with the moistening roll with an intermediate layer of the hygiene paper. The dispenser can be divided into a base housing and an insertion part. The advantage of the dispenser consists of commercially available toilet paper being made available and of moistened hygiene paper being dispensed in a specific length or in any desired length and of the dispenser being made simply and being easy to handle.Type: GrantFiled: November 19, 2002Date of Patent: March 6, 2007Inventor: Werner Kaufmann
