Abstract
A porthole window includes a circular base section being a viewing glass having a substantially planar inner surface and a border region, and a rigid plastic side-wall section of the bowl tapering in a direction of the base section. The viewing glass, over an entire border region of the base section, is curved in a direction of the side-wall section such that the border region of the base section forms a rounded glass shoulder. On the outer border of the glass shoulder, the viewing glass has an annular connecting section running obliquely in relation to the inner surface of the base section and, at its head end, firmly engages with the inner end of the side-wall section.
