    • A seat cover comprises a sheet of biodegradable material wound about itself so as to define a hollow core, with the hollow core having an interior perimeter sufficiently large so as to fully encompass a toilet seat about a trans-axial perimeter thereof when inserted thereover. A seat cover also may comprise a plurality of biodegradable balls connectedly associated with a substrate, wherein the substrate has substantially the shape of a toilet seat. A method of making a seat cover comprises winding a sheet of biodegradable material about an object having a trans-axial perimeter about the same size as a toilet seat, wherein a wind partially overlaps a preceding wind such that winding progresses in an axial direction along the object with each successive wind, and removing the wound sheet from the object. A method of making a seat cover also comprises connectedly associating a plurality of biodegradable balls to a substrate along an exterior surface thereof, wherein the substrate has the shape of a toilet seat.
    • 座椅护罩包括围绕其本身缠绕的片状的生物可降解材料,以便限定中空的芯,其中空芯具有足够大的内部周长,以便当插入其中时完全包围围绕其跨轴周边的马桶座圈。 座椅套还可以包括与衬底连接的多个可生物降解的球,其中衬底基本上具有马桶座的形状。 一种制作座椅罩的方法包括将一片可生物降解材料卷绕在具有与马桶座圈相同尺寸的跨轴周长的物体上,其中风部分地与先前的风相重叠,使得卷绕沿轴向方向沿着 对象,每个连续的风,并从对象中去除伤口片材。 制作座椅罩的方法还包括沿其外表面将多个可生物降解的球连接到基底上,其中基底具有马桶座的形状。
