Abstract:

A molding system and related method for forming a molded article, such as a container, is disclosed. In one embodiment, the injection material is supplied though a side gate and drawn into the mold cavity using a vacuum assist and optional heating of the mold portions, if necessary. This creates a preform having a closed end with a smooth outer surface without gate marks or other vestiges of the injection molding process. The preform is then blow molded to form an article or container having a smooth outer surface adjacent to a closed end thereof.

Abstract:

A double container, structure for use in forming a double container, and related method are disclosed. The double container may be formed by connecting first and second open-ended containers in a generally opposed relationship. In the preferred embodiment, pairs of matching projections extend from the end wall of each container. One or both projections on one container may include a melting area or region that is placed in contact with the corresponding projection on the opposite container. Ultrasonic energy is then supplied to melt the melting area or region as the containers are pressed together. Upon solidification, a bond is thus formed between the projections to create the double container. In a second embodiment, an intermediate structure for receiving a second container is attached to the first container, such as by ultrasonic welding.
