    摘要: This relates to a container, particularly adapted for receiving a hot-fill product. Most particularly, the container is a blow molded plastic container with the principal plastic material being a polyester resin. Critical areas of the container have walls of a laminated construction with preferably at least five layers of which two layers is a moisture barrier layer. The polyester resin primarily utilized, PET, is very sensitive to moisture pickup and by utilizing the moisture barrier layers, the moisture pickup of the primary resin may be reduced with a resultant reduction in the shrinkage and distortion of such container when hot filled.

    摘要: Method and apparatus for sequentially delivering multiple shots of polymer material to a plurality of mold cavities to form multilayer articles. A first shot of greater than 50% of the total article weight of a first polymer material is simultaneously delivered to a plurality of mold cavities using, at each cavity, a chamber of predetermined volume that is prefilled with the first polymer material. A second shot of no greater than 10% of the total article weight of a second material is simultaneously delivered to all of the cavities beginning subsequent to the step of delivering the start of the first shot delivery step. The second shot of second material is delivered through a manifold channel that fluidly communicates with each cavity, and is injected to all cavities under pressure exerted by a source of the second material that is common to all of the plurality of cavities.

    摘要: A method of reheat blow molding a container includes the step of positioning a preform in a blow mold cavity with at least one of the walls having an opening with an anvil received therein for movement between a first position outside the cavity and a second position at least partially within the cavity. Further, expanding the preform within the cavity while moving the anvil from its first position to its second position so that the expanding preform forms a pocket for receiving a handle therein.

    摘要: A method making a plastic container in accordance with one aspect of the present invention includes molding an intermediate container product having a body and a moil integral with the body. The body is of layered construction that includes at least one layer of barrier resin that extends part-way into but not throughout the moil. The upper portion of the moil, in which the barrier material is absent, is removed for recycling as process regrind. The lower portion of the moil is removed to form the container. In the preferred embodiment of the invention, the upper portion of the moil is removed in a laser trimming operation. The lower portion of the moil is removed in the preferred embodiment of the invention by inserting a plug into the open end or mouth of the container, and employing a cutting tool that is positioned by the plug for accurately trimming of the container product with respect to the mouth of the container. The cutting tool preferably is either a pair of shear rollers or a laser cutting tool.

    摘要: A method of making a plastic container having a threaded wide-mouth finish includes providing a preform having at least an exterior surface of molded polyester construction. The preform is placed in a mold cavity having a first portion for forming a container body, a second portion adjacent to the first portion for forming a cylindrical finish wall without threads, and a third portion adjacent to the second portion for forming a trim dome or moil. The preform is expanded within the mold cavity to form a one-piece intermediate product that includes a body, a cylindrical wide-mouth finish wall and a moil. After removing the intermediate product from the cavity, the moil is severed from the end of the finish wall. At least one thread is then formed on the finish wall by engaging the finish wall with at least one thread-forming tool, which may be heated to facilitate the forming operation.

    摘要: Method of securing a separate handle (18) to a plastic blow-molded container, the container having a molded external flange which is not subject to stretching during the blow-molding process. The flange has a substantially flat underside face and serves as a rigid support for the handle (18) when a substantially flat upper abutment surface of the handle (18) is positioned against the flange. Preferably, the upper end of the handle (18) has a downwardly extending lug (15) which is surrounded by the blow-molded sidewall of the container. The preform and handle (18) can be brought together into position where the upper end of the handle is adjacent to the underside of the external flange by relative movement of the preform and handle (18) towards each other along a first path which is substantially perpendicular to the longitudinal axis of the preform. In addition, the handle (18) and preform can be brought together prior to their introduction into the mold, and then introduced together into the blow mold along a second path which is also substantially perpendicular to the longitudinal axis of the preform. Further, the preform can be heated prior to introduction into the mold, while the handle (18) remains unheated.
