Definitions

  • the present disclosure relates broadly to a toilet seat cover, to a toilet seat, a method of manufacturing a toilet seat cover and to a method of manufacturing a toilet seat.
  • Flush toilets typically comprise a bowl portion (or toilet bowl) which receives e.g. waste.
  • the bowl portion has an opening which is defined by the rim of the bowl portion.
  • the rim can be overlaid with a sanitary/toilet seat.
  • the toilet seat is typically hinged to an end of the rim, to allow the seat to be laid over the rim when sitting is desired.
  • the seat can be lifted or rotated off the rim into an erect position substantially perpendicular to the opening of the bowl, and may be rested against a wall surface or water tank of the flush toilet.
  • toilet seats may be soiled or dirty which discourage users from sitting on or to even come into contact with the seats.
  • a seat laid over the rim may be soiled by a standing male user.
  • cleaners may be employed to attempt to clean each toilet seat as soon as it is used. However, this may be a costly and non-practical way of matching number of cleaners to peak period usage of toilets. Moreover, cleaners may not have applied any antiseptic agents or sterilizing chemicals to clean the surface of the seat.
  • Some users may use disposable covers which may be placed on the seats directly.
  • seat covers typically comprise a sheet of paper shaped like toilet seats.
  • Such sheets are typically of inadequate thickness for manufacturing cost effectiveness and may break easily when not handled properly, particularly when the disposable covers are wet, as a result of e.g. a wet toilet seat or urine from a previous user.
  • the paper disposable covers generally do not fit well on toilet seats as they are smaller in size compared to the toilet seats. As such, users have to lay a few pieces of such paper disposable cover, on top of each other in order to cover the seats completely, and also to provide sufficient thickness. This inefficient coverage results in additional cost incurred. Further, such sheets do not rest properly on toilet seats and tend to slip when the user sits on it.
  • a toilet seat cover comprising a top sheet of material; a bottom sheet of material, the bottom sheet coupled to the top sheet on two coupling edges of the bottom sheet; said cover capable of receiving a toilet seat between the top and bottom sheets.
  • the two coupling edges may be opposing outer edges; such that the cover is capable of receiving the seat between the opposing outer edges.
  • the top and bottom sheets may comprise respective hole portions, the respective hole portions aligned to form a central opening of the cover; said central opening capable of being aligned substantially with a hollow portion of the toilet seat when the toilet seat is received between the top and bottom sheets.
  • the toilet seat cover may further comprise a flap hinged from a side of the central opening; said flap being capable of extending through the hollow portion of the toilet seat when the toilet seat is received between the top and bottom sheets.
  • At least one of the top and bottom sheets may comprise one or more perforations for forming the respective hole portion when the perforations are torn.
  • the perforations may allow the flap to be formed when the perforations are torn.
  • At least one of the top and bottom sheets may comprise one or more additional perforations for reducing a size of the flap, when the one or more additional perforations are torn.
  • the flap may be hinged proximate a front edge of the cover.
  • the top and bottom sheets may each comprise a fluid permeable material. At least one of the top and bottom sheets may comprise a fluid impermeable material.
  • At least one of the top and bottom sheets may comprise an internal layer of material and an external layer of material, the external layer being exterior of the cover.
  • the internal layer may comprise a fluid impermeable material.
  • the external layer may comprise an absorbent material.
  • the top and bottom sheets may be rectangular in shape.
  • the bottom sheet may be further coupled at one or more other edges of the bottom sheet to the top sheet, each said other edges corresponding to a coupling edge; each said other edge disposed from the corresponding coupling edge such that each other edge and respective coupling edge forms a sleeve for receiving one fork of a horseshoe shaped-toilet seat.
  • the other edges may be joined together substantially along respective perimeters to form a ring.
  • the bottom sheet may be further coupled to the top sheet on a front edge of the bottom sheet; and the cover further comprises a mouth for allowing the seat to be inserted through.
  • the bottom sheet may further comprise an additional opening positioned between the central opening and a mouth edge, said additional opening extending across substantially the opposing outer edges.
  • the top and bottom sheets may each further comprise peripheral areas extending beyond a surface area of a received toilet seat, capable of being folded and disposed under the toilet seat.
