<p>The hygienic covering for a lavatory seat consists of a rectangular piece of paper (4) which can be disposed of after use. The paper sheet is slightly larger than the top of the seat. In the middle of the sheet is a perforated tear-off circular line (5) so that a central hole can be torn off to expose the aperture of the seat pan. The sheet is folded in two lengthwise, with each strip again folded in two so that the sheet is concertina-shaped inside its package-box (1). The box has a slot (3) on the top (2) through which the sheets are extracted.</p> |
