Abstract: Composite molded articles having relatively rigid and flexible resin regions are bonded to one another along an interfacial fusion zone. A normally solid thermoplastic polyalkylene terephthalate resin preform (which will constitute the relatively rigid region of the composite article) is placed in a mold cavity. The flexible region of the composite article is then formed by introducing a molten thermoplastic polyester elastomer resin into the mold cavity at a temperature which is greater than the melt temperature of the solid preform. The introduced thermoplastic polyester elastomer resin contacts and at least partially plasticizes a surface region of the solid preform along the interfacial bonding zone within the mold cavity to thereby cause the polyester elastomer resin to coalesce with the at least partially plasticized surface region of the polyester resin. Upon cooling and solidification, the solid preform and the polyester elastomer are fused to one another along the interfacial bonding zone.

Abstract: An aerosol container includes a cylindrical container body having an open end, a lid injection-molded from a thermoplastic resin material and sealingly coupled to the container body and defining a mouth opening, and a metal dispensing cap sealingly coupled to the lid and closing the mouth opening. The dispensing cap is provided with a dispensing nozzle for dispensing the contents of the container in aerosol form. The lid itself includes an upper annular mounting bead sealingly coupled to the dispensing cap and having an interior upper surface (that establishes the mouth opening), and an interior lower surface that is radially outwardly disposed relative to the interior upper surface thereof. Important to the present invention, the lid includes at least three gates circumferentially equally spaced-apart relative to one another along the interior lower surface of the mounting bead.

Abstract: An automotive outer door operating member is integrally formed of a thermoplastic resin and comprises a handle and arms extending from the handle; characterized in that the thickness ratio of the root of each arm to the handle at the junctions of the arms and the handle is 0.5 or below.
