ABSTRACT:
This specification discloses apparatus for connecting handles, or other parts, to plastic injection blow molded containers such as buckets, pitchers and other articles; the handles being parts that are not molded integral with the blow molded containers, but that are stiffer and stronger parts than the blow molded walls of the containers. The blow molded element is made with recesses for receiving the bales, or handles, and is made flexible so that end portions of the handles can be forced into the recesses by expanding the entrances to the recesses. The fit is designed to give the maximum undercut that cannot be pulled out of the mold without damaging the part. The mating part can be made to snap in with a design that minimizes the ability to remove it, such as for a paint can.
