ABSTRACT:
The present inventions relates to a mold for forming a one piece flip-top cap and process for making such a cap. A mold for forming and closing the one piece flip-top cap prior to ejection from the mold includes a first mold part, an inner core mold part and a second mold part movable into relationship with the first mold part and the inner core mold so as to form a mold cavity therebetween. The mold produces a one piece flip-top cap with a living hinge between the body and lid of the cap and which is maintained in a closed position upon ejection from the mold. Pull straps are used to ensure full closure of the cap lid to the body prior to ejection.
