Title: Deodorizing floor sheet
Inventor: IHARA HIROSHI
IPC: A47K17/02
Filed: 2002-08-08
Abstract: <P>PROBLEM TO BE SOLVED: To restrain generation of a malodor by forming a floor sheet used by being laid on a floor surface of a toilet in a cleaning unnecessary and easily replaceable disposable form.  <P>SOLUTION: This floor sheet 1 is formed by laminating a surface layer sheet 2 having a water absorbing effect on a surface and an impervious sheet 3 having a waterproof effect on the reverse. Both are laminated by using pulp nonwoven fabric including chitosan and using pulp as the surface layer sheet 2 and using a polyethylen resin as the impervious sheet 3. The nonwoven fabric has a characteristic of not getting loose even when being cut out, and since the polyethylen resin is freely cut, this floor sheet 1 can be freely cut out according to a shape of a toilet bowl so that clearance is not formed between the floor sheet and the toilet bowl. An ammonia smell generated from a waste material such as urine absorbed in the pulp nonwoven fabric of the surface layer sheet 2 is removed by the deodorizing function possessed by the chitosan. The impervious sheet 3 prevents stain of the floor surface since moisture is not passed below, and the floor sheet 1 becomes strong by lamination of this resin, and is not torn by friction in use.  <P>COPYRIGHT: (C)2004,JPO
