ABSTRACT:
A latch member of a case or similar container blow-molded from thermoplastic material is pivotally and permanently secured to the case by a bearing formed substantially simultaneously with and from the same thermoplastic material as the body of the case. Formation of a permanent bond between the bearing member and the latch member is avoided by employing a latch member formed of material having a higher melt temperature than the material used in the formation of the main body of the case and the bearing member, and also by effecting relative movement between the latch member and the bearing member while the thermoplastic material forming the bearing member is still in a heated condition. Apparatuses for positioning the latch member within the mold are also disclosed.
