Patent number: 9884442Abstract: An injection molding device including a middle flow channel which forms an intermediate layer of a preform which is subject to biaxial stretch blow molding. The middle flow channel s segmented into a predetermined number of flow sub-channels by vertical blocking rib piece(s). Side wall's upstream portions of the vertical blocking rib piece are formed as angled surfaces whose distance from each other decreases from the downstream side to the upstream side, and/or, an end portion of the vertical blocking rib piece that is located on the downstream side is tucked in at least one of the inner flow channel and the outer flow channel.Type: GrantFiled: May 15, 2014Date of Patent: February 6, 2018Assignee: YOSHINO KOGYOSHO CO., LTD.Inventors: Tamotsu Toyoda, Hiroshi Hosokoshiyama, Mamoru Sato, Yasuhiro Ishizawa

Patent number: 8061540Abstract: This invention is aimed at preventing containers effectively from performance deterioration, such as exposure of the recycled material at the neck and reduced strength of the pinch-off portion, as caused by a high ratio of recycled material used as the middle layer. There is provided a multi-layered blow-molded container molded from cylindrical multi-layered parison, wall of the container comprising at least an outer layer, an inner layer, and a middle layer, wherein the outer and inner layers are made of a same synthetic resin, while the middle layer is made of a recycled material consisting primarily of the synthetic resin used for the outer and inner layers. This container is characterized in that it has either middle-layer excluded zones or a thin middle-layer zone. These zones are provided at a predetermined range along the direction in which the parison is extruded.Type: GrantFiled: August 9, 2007Date of Patent: November 22, 2011Assignee: Yoshino Kogyosho Co., Ltd.Inventor: Tamotsu Toyoda
