  • Patent number: 6029289
    Abstract: An injection-moulded plastic child's chamber pot includes a basin part whose wall merges with a seating and supporting part at the top thereof. The front wall part of the basin part slopes obliquely upwards and rearwards in the position of use of the pot. A bottom edge region of an outer wall part, formed integrally with the basin part and the seating and supporting part, and extending downwardly beneath the underside of the basin part, forms a bottom support surface via which the pot is intended to rest on a supporting surface. All pot surfaces define a release angle in relation to the parting direction of two tool halves which form the injection-moulding tool in which the pot is produced and which have a parting plane which coincides with the plane of the support surface and slopes in relation to the normal to the parting direction at an angle corresponding to the angle of inclination of the front wall part plus the release angle of said front wall part.
