摘要： A method of forming a wide mouth blow molded thermoplastic container (1) comprising the steps of i) stretch blow molding from a preform (5), an intermediate article defining the container with the mouth being threaded (12) and/or flanged, the mouth terminating in an accommodation element (10) having a neck finish (6) that supports the preform (5) in the blow mold (11); ii) heat setting the intermediate article including the entire container (1) while still in the mold (11); and iii) removing the intermediate article of manufacture from the mold (11) and severing the accommodation element (10) to produce the container (1), and an article when made by the method. The method also includes post forming of a rim portion (17, 18, 19) of the container (1) following separation of the container (1) from the accommodation element (10).

摘要： A multi-cavity coinjection mold (10) and method for simultaneously producing a plurality of multi-layered articles comprising: a mold structure defining a plurality of mold cavities (12); a first supply source (26) for supplying metered amounts of a first molding material; a second supply source (28) for supplying metered amounts of a second molding material; a hot runner system (24) in communication with the first (26) and second (28) supply sources for conveying the metered amounts of the first and the second materials separately to a region proximate each of the cavities; a valve mechanism (20) per cavity for receiving the metered amounts of the first and second materials from the hot runner system (24) and for sequentially supplying desired quantity of the first and second materials contiguously to each cavity (12). A pin scavenging material packing arrangement is also provided.
