Title:
MANUFACTURING DEVICE FOR BLOWINGGIN MOLDED PLASTIC ARTICLE
Document Type and Number:
Japanese Patent JPS56106830
Kind Code:
A
Abstract:
A method particularly adapted for making pinched-shut, non-blown portions of a blown article, e.g. the non-blown handle openings in a blown plastic jug including engaging a localized portion of a blowable shape, which portion corresponds to a non-blown portion of the final blown article, with a blow mold projection prior to complete enclosure of the blown shape in the blow mold. Such engagement fixes the engaged portion to the blow mold for joint displacement during further blow mold closure. This engagement can be obtained by either (1) specifically shaping the blowable shape for engagement by the mold pinching portions or (2) utilizing retractable abutments carried by the mold itself.
