摘要:
Method of making a fastening element (10) and fastening element (10) comprising a first portion (12), a second portion (14) and a film hinge (16) provided between the first and second portions (12, 14) and connecting the first and second portion (12, 14). The film hinge (16) is adapted to be bent and comprises a first structure (18) extending in a first direction (X1), a second structure (20) extending in a second direction (X2) and a third structure (22) provided between the first structure and the second structure. The third structure (22) comprises an interface part (24) extending between the first and second structure (18, 20) and a bulge (26) protruding from the interface part (24), in order to allow an injection moulding of the fastening element (10) through the third structure (22).

摘要:
A blow molded plastic bottle with a suspending member formed on its neck portion. In the stage of injection-molding a preform made of a crystalline resin material, the suspending member shaped like a flat plate is formed integrally on the side of the lower part of the neck portion in such a way as to extend laterally with its flat surface directed upward. The suspending member has its end integrally formed on the side of the neck portion and stretched by pulling to form a thin-walled bend. The stretched-orientation characteristics of the bend are effectively exploited to impart bending strength and flexibility to the suspending member so that it is bent freely in upward and downward directions.
