摘要： Provided is an injection molding device including a middle flow channel (16) which forms an intermediate layer of a preform which is subject to biaxial stretch blow molding. The middle flow channel (16) is segmented into a predetermined number of flow sub-channels by vertical blocking rib piece(s) (20). Side wall's upstream portions (20b) of the vertical blocking rib piece (20) 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 (20) that is located on the downstream side is tucked in at least one of the inner flow channel (15) and the outer flow channel (17).

摘要： A technical problem of this invention is to control the behavior of an intermediate layer in the preform bottom at high productivity and in a high degree of accuracy in the injection molding of a preform having a second-resin layer laminated with main-resin layers A principal means of this invention to solve this technical problem is a process for injection molding a preform in a test tube shape having an intermediate layer of a second-resin layer laminated with main-resin layers. This process comprises the steps of: supplying a main resin from an outer flow channel and an inner flow channel to a joined flow channel at a predetermined supply velocity for a predetermined period of time; supplying a second resin from a middle flow channel to the joined flow channel simultaneously with the main resin at a predetermined supply velocity for a certain period of time within the predetermined period of time; and sliding a shut-off pin to bring the pin forefront to a predetermined position near an outlet of the inner flow channel, which is open to the joined flow channel, previously before the second resin is supplied, or during a period of time starting after a predetermined time from the start of the second resin supply and ending with the termination of the supply, so that the velocity of main resin supply from the inner flow channel to the joined flow channel is reduced to a predetermined level by adjusting the degree of aperture for the outlet.

摘要： Provided is a synthetic resin container or bottle with a window obtained by subjecting a test tube-shaped preform made by injection molding to biaxial stretch blow molding. The container includes a transparent base layer (211); a circumferential wall formed of the transparent base layer (211); and a light-blocking or opaque intermediate layer (212) formed in the base layer (211) in a laminated manner to cover an area of a predetermined height of the circumferential wall. The intermediate layer (212) is formed in a laminated manner over an area covering an entire circumference of the circumferential wall excluding a non-laminated section (213), where the intermediate layer (212) is not formed, that extends in a shape of a longitudinal strip along the central axis direction of the container on the circumferential wall of the container. The non-laminated section (213) serves as a window section (213w).

摘要翻译：本发明的技术问题是在具有与主要树脂层层压的第二树脂层的预成型件的注射成型中以高生产率和高精度控制预成型件底部中的中间层的行为。解决该技术问题的本发明的主要手段是注射成型具有与主要树脂层层压的第二树脂层的中间层的试管形状的预制件的方法。该方法包括以下步骤：以预定供应速度将主树脂从外部流动通道和内部流动通道供应到接合流动通道达预定时间段; 在预定时间段内以预定供应速度将主树脂同时从中间流动通道供应到接合流动通道一段特定时间; 并且在供给第二树脂之前或者在开始之后的一段时间期间滑动关闭销以使销前端到达内部流动通道的出口附近的预定位置，该内部流动通道的出口向接合流动通道开放从第2树脂供给开始到供给结束为止的规定时间，通过调整开口度，将从内侧流路到结合流路的主树脂的供给速度降低到规定的水平为出口。

摘要： A problem to be solved by this invention is providing a device enabling to control the problem of delamination in the laminated and biaxially drawn, blow molded bottle (201). A major means of this invention to solve this problem is provision of a device to be used to injection mold a laminated preform (101) and draw it biaxially so that blow molded bottle (201) exhibits vertical connecting zones (214a) having no intermediate layer and having substrate layers (211, 212, 213) welded directly with each other are formed in parallel in a circumferential direction and in a plural number along an axial direction of the bottle and are disposed on both right and left sides of each intermediate layer (213) segment to be formed in this height range (h2), and that horizontal connecting zones (214p) having no intermediate layer and having substrate layers welded directly with each other are also formed in parallel in an axial direction and in a plural number along a circumferential direction of the bottle and are disposed on both upper and lower sides of each intermediate layer segment to be formed, thus allowing the intermediate layer (213) to be segmentalized in the circumferential and axial directions by both the vertical (214a) and horizontal (214p) connecting zones.
