  • Patent number: 6298488
    Abstract: A kitchen grip or implement for kitchen use is composed of a water-resistant and stain proof material having temperature control characteristics. Such a material forms the implement from at least one sheet having a textured, recessed or irregular surface providing a non-slip contact surface while the opposite surface of the sheet is composed of a close fabricated fabric which is affixed to the sheet of non-slip contact surface material. The fabric sheet may be a sheet of nylon/polyester composition which is affixed to the non-slip contact surface sheet which may be composed of a chloride rubber. The sheets are die cut to the shape of a useful implement such as a hand mitt, a trivet, a lid holder or the like. A two-piece implement such as a hand mitt requires that two sheets of the fabric and chloride rubber composition be sewn together by means of a zigzag lock stitch employing nylon thread.
