Definitions

  • This disclosure is generally directed to toilet equipment and more particularly to a toilet lid with a sculptured, decorated surface which may be assembled to a toilet seat.
  • Toilet seats have existed in various forms for many decades. Usually, they comprise a seating board having a circumferential seating surface around a hole that is substantially positioned in the middle and matches the aperture of the toilet bowl.
  • the seating board provides a surface on which the occupant can sit comfortably.
  • such toilet seats often comprise a lid, which may cover the seating board and thus provide a protective cover for both the seating board and the toilet bowl aperture.
  • toilet seats both seating board and lid parts, have plain, non-adorned surfaces which do not include any type of embellishments such as painting, photographs, or engraving. Additionally, the choice of material for the toilet lid and seat further limits the types of embellishments that may be utilized. While toilet lids and seats made of plastic materials may be fabricated in various shapes and sizes though injection and or compression molding, the choice of material renders these products expensive. Toilet seats primarily made of wooden materials can only be cost-efficiently manufactured in a limited variety of shapes. In addition, only a small proportion of toilet seats available on the market have adorned or decorated surfaces. For instance, toilet seat lids can be adorned with silk-screen printing, hand painting, water-transfer printing, heat transfer printing, and the like.
