ABSTRACT:
A process and apparatus for the manufacture of a deodorant stick holder comprising a perforated cage and a hook for retaining the cage in a toilet pan, the perforated cage itself being formed by two half-cages joined by flanges at their facing open ends. In the method the hook together with a connecting ring, is moulded in one cavity simultaneously with the moulding of one half-cage in another moulding cavity of a single mould. Upon opening of the mould the connecting ring is first displaced axially to snap fit onto the half-cage end flange and the so assembled unit is then stripped from a core of the mould.
