Exterior rim wash bowl
A one-piece bowl including an open top, a bottom opening, a rim portion, an interior space and a plurality of cavities is provided. The rim portion substantially surrounds the bowl near the open top, and an inner channel is formed along and within the rim portion. The interior space is substantially defined by an interior surface, the open top and the bottom opening. The plurality of cavities extends from the inner channel to the interior space. The inner channel and the cavities are configured to pass fluid from an outer fluid source to the interior space. A mold assembly and a method for forming a one-piece greenware piece for the bowl are also provided. The mold assembly includes a top mold component and a bottom mold component that are configured to mate and thereby form a reservoir substantially defining the bowl.

4. The bowl of claim 3 , wherein the interior space is configured to continuously taper from the upper edge of the rim portion to the bottom opening.
5. The bowl of claim 1 , wherein the rim portion projects away from the interior space.
6. The bowl of claim 1 , wherein the cavities are formed in a substantially radial direction.
7. The bowl of claim 1 , wherein the plurality of cavities is oriented at a slight downward angle from the inner channel to the interior space.
8. The bowl of claim 1 , wherein a section of the interior surface of the bowl on which the cavities are formed has an angle of inclination that is closer to vertical than horizontal.
9. The bowl of claim 1 , wherein the bowl includes a fluid supply hole for introducing fluid into the inner channel.
10. The bowl of claim 1 , wherein the bowl includes a base allowing the bowl to stand on its own.
11. The bowl of claim 10 , wherein the bowl substantially constitutes a receptacle portion of a toilet system, and the inner channel and the bottom opening are operably connected with a flushing system of the toilet system.
12. A one-piece bowl including:
an interior surface defining an open top, a bottom opening, and an interior space;
a rim portion substantially surrounding the bowl near the open top;
an inner channel formed along and within the rim portion; and
a plurality of cavities extending from the inner channel to the interior space,
wherein the interior space extends to the upper edge of the rim portion;
wherein the inner channel and the cavities are configured to operably pass fluid originating from an outer fluid source to the interior space, and
wherein the rim portion projects away from the interior space such that the rim portion does not extend into the interior space, and the interior surface of the rim portion and the interior surface are integral components that form a continuous smooth surface defined by an arc of a line.
13. A one-piece bowl including:
an interior surface defining an open top, a bottom opening, and an interior space;
a rim portion substantially surrounding the bowl near the open top;
an inner channel formed along and within the rim portion; and
a plurality of cavities extending from the inner channel to the interior space,
wherein the inner channel and the cavities are configured to operably pass fluid originating from an outer fluid source to the interior space, and
wherein an interior surface of the rim portion and the interior surface are integral components that form a continuous smooth surface defined by an arc of a line that is free of substantial protrusions, corners, and edges projecting into the interior space of the bowl.
14. A one-piece bowl including:
an interior surface defining an open top, a bottom opening, and an interior space;
a rim portion substantially surrounding the bowl near the open top;
an inner channel formed along and within the rim portion; and
