  • Mat in the form of a liner or pad for sanitary facilities and method of producing the mat by injection molding
    Patent number: 6289528
    Abstract: A Mat (1) in the form of a liner or pad for sanitary installations is formed of a carrier (3) of flexible plastic with suction cups (5) located on its bottom (4) and a layer of nonwoven fabric (2) on its top (1.1) is constructed to enable the mat (1) to be efficiently produced and for the mat to have good adhesion between the nonwoven fabric (2) and the carrier (3) even when experiencing high squeezing stress. This is achieved by making the carrier (3) of a thermoplastic elastomer (TPE) injecting the elastomer onto the back of nonwoven fabric (2) in an injection mold.
