摘要： An injection molding apparatus produces a one-piece molded end closure has a pull ring spaced from a main panel, which has an annular flange extending therefrom and may have score lines. The pull ring is connected to the main panel by a tenon. The apparatus includes a slidable member disposed in a first passage in a core having a cavity surrouding a portion of the first passage. The core and the slidable member have end surfaces spaced from an end surface of a cavity insert to form a recess therebetween into which molten plastic is injected to form the main panel. The core has a second passage communicating the recess with the cavity in the core so that the molten plastic flows into the cavity to form the pull ring with the tenon being formed in the second passage in the core. The slidable member is removed from the first passage prior to moving the cavity insert away from the core to enable removal of the pull ring through the first passage in the core and the tenon from the second passage in the core without any tearing of the pull ring or rupturing of any score lines in the main panel when the end closure is removed from the core.
摘要翻译： 注射成型设备产生一体式模制端盖，其具有与主面板间隔开的拉环，其具有从其延伸的环形凸缘并且可具有刻痕线。 拉环通过榫头连接到主面板。 该装置包括设置在芯中的第一通道中的可滑动构件，其具有围绕第一通道的一部分的空腔。 芯部和可滑动部件具有与腔插入物的端面间隔开的端表面，以在其间注入熔融塑料以形成主面板。 芯部具有使凹部与芯体中的空腔连通的第二通道，使得熔融塑料流入空腔中以形成拉环，其中榫头形成在芯体中的第二通道中。 在将空腔插入物从芯体移开之前，将可滑动构件从第一通道中取出，以便能够通过芯中的第一通道和榫头从芯中的第二通道移除拉环，而不会拉动拉环 或者当端盖从芯中取出时，在主面板中的任何刻痕线断裂。

摘要： A one-piece molded end closure has a pull ring spaced from a main panel having an annular flange extending therefrom. When the end closure is frangible through having score lines formed in the main panel, the pull ring is connected by a tenon adjacent a score point, which is the junction of two score lines and inside of the inner diameter of the pull ring, so that pulling on the pull ring, which is substantially parallel to the main panel, starts rupturing of the two score lines. The end closure also may be a plug type having a friction fit within a container whereby there are no score lines; the pull ring is still used to remove the end closure from the open end of the container. The method and apparatus for molding enable production of the end closure as one piece without any tearing of the pull ring or rupturing of the score lines when the end closure is removed from the molding apparatus. The main panel may be formed with a single continuous score line and the pull ring not at the center of the main panel. The end closure also may be formed integral with a cylindrical side wall of the container rather than having the end closure molded separately and then being sealed to an open end of a container.
