  • Patent number: 4524474
    Abstract: An absorption pad useful for protecting a bed, furniture, or the like, includes a lower liquid impervious material layer and an upper liquid absorbent material layer laminated thereto. The liquid absorbent layer is impregnated with strings or filaments of a liquid resistant agent which does not stiffen the pad. The strings or filaments form a grid-like pattern for defining compartments between the strings over preferably the entire area of the absorption pad, thereby for limiting the spread of liquid over the pad. The layers are laminated together, and may be laminated by an adhesive. The laminating areas may be in a filament pattern corresponding to and overlapping the filament pattern of the strings of the liquid resistant agent.
