Claim 1
Independent Claim
172 words
A roll of paper covers for a toilet bowl seat which seat has laterally spaced bowl-shaped side portions, said roll comprising a web of a plurality of lengths of paper at least as long as the front to back dimension of a bowl-shaped side portion and having a width greater than the width of the bowl-shaped side portion, said lengths of paper being defined by continuous transverse lines of perforations, each length of paper having at least one linear line of perforations extending inwardly from the opposite side edges substantially perpendicular thereto and at a position intermediate the ends of said lengths of paper, said line of perforations terminating short of the middle portion of each length of paper leaving the middle portion of each length of paper unperforated, the distance across said middle portion being sufficient to make the paper strong enough to remain untorn under a force substantially in the longitudinal direction of said web and which is sufficient to tear the paper along said continuous transverse lines of perforations.
