Description

  The present invention relates to a toilet seat, and more particularly to a toilet seat formed by joining a toilet seat front member and a toilet seat back member.

  In many cases, such as a heated toilet seat, a toilet seat front member and a toilet seat back member are joined and the inside is hollow. The joint surface (interface) between the toilet seat front member and the toilet seat back member is exposed on the side surface and the lower surface of the toilet seat to form a streak portion. Dirt easily enters the streaks. If dirt enters this mating surface, it cannot be removed by wiping, and streaky dirt remains.

  In particular, the toilet seat front member and the toilet seat back member made of synthetic resin are generally formed by injection molding. However, in order to prevent burrs from being generated in the injection molded product, the toilet seat front member and the toilet seat back member are usually formed. The corner edge of the member is rounded. By rounding the corner edge in this way, the mating surface of the toilet seat front member and the toilet seat back member becomes a streak portion having a relatively large width and is exposed on the side surface or the lower surface of the toilet seat. In addition, even if this stripe-shaped part ultrasonically welds a toilet seat front member and a toilet seat back member, it does not eliminate.

Japanese Patent Laid-Open No. 2001-149269 describes that the mating surface is an inclined surface in order to prevent dirt from adhering to the mating surface between the toilet seat front member and the toilet seat back member.
