DEFINITION

Classification: 428/174

(under subclass 98) Product wherein the web or sheet, or a component thereof, has nonthickness surfaces* which are (1) defined other than by two parallel planes and (2) equidistantly spaced at all points.

(1) Note. Excluded from this definition of nonplanar is a roll or coil of material; the product itself must be nonplanar, not the manner of packaging or storing.
