摘要： Overmolded containers (20) and methods of manufacture thereof are disclosed, which may provide enhanced visual and tactile characteristics, enabling innovative packaging designs, improved grippability and thermal insulation. The containers can be made cost effectively manner, with minimal impact on polymer recycling streams. The methods of making the container include the steps of providing a container preform (12) which comprises a thermoplastic polymer, such as a PET copolymer; overmolding an elastomeric material (14) over at least a portion of the preform to form an overmolded preform; and blow-molding the overmolded preform to form an overmolded container. In one embodiment, the overmolded container is a beverage container. Overmolded preforms are also disclosed.

摘要： A polyester container, such as a polyethylene terephthalate container produced by blowmolding can be given a modified exterior surface, such as a frosted appearance, by being blowmolded in a mold that has an irregular, pitted surface, the mold being at a temperature of at least about 40 °C above the glass transition temperature of the polyester resin. At this temperature of the mold the polyester resin will flow into the irregularities of the mold and produce a frosted appearance to the exterior surface of the container. One technique to give the mold an irregular, pitted surface is to grit-blast the interior of the mold that is to have the frosted appearance. Other modifications other than a frosted appearance can be imparted to the surface of a container. These include recesses, projections and serrations.
