Ceramic toilet bowl and method for manufacturing the bowl

Abstract

A ceramic bowl obtained by means of casting in moulds comprises: a liquid collection pan () having a main axis (Z) of extension; a liquid distribution rim () having at least one portion configured to reproduce the top edge () of the pan () along a common plane (P) of lie; the rim portion () has a tubular chamber () with toroidal cross-section for the passage of liquids and having as axis of rotation the axis (Z) of the pan (); a separate outer casing () for housing the single component formed by pan () and rim (); the bowl comprises a first set of perimetral surfaces () which define one part of the tubular chamber () of the rim () and the surface joining the rim portion () to the pan () and which are parallel to each other and extend in a direction transverse to the common plane (P) of lie, and a second set of perimetral surfaces () which define the other part of the tubular chamber () and extend parallel to the plane (P) of lie and are connected to the first set of surfaces () so as to configure continuous outer surfaces devoid of recesses or projections; one of the surfaces () of this second set defining the top wall of the tubular chamber () is provided with a projecting flange () forming a surface () for resting the rim () on a top surface () of the casing ().
