摘要： A three-piece tank assembly including a tank, a support base, and a support liner. The tank has a conical bottom with a discharge conduit at its apex; a longitudinally corrugated antisplash filling trough integrally formed with a sidewall of the tank; and an integrally formed cover including a bunghole for providing access to the filling trough. The discharge conduit may include a flow valve and check valve. The base includes a sidewall for nesting engagement with the tank sidewall, a flat ground-engaging surface and transverse longitudinal slots for receiving the forks of a forklift. The support liner has an upstanding wall and a conical top wall for supporting the conical bottom of the tank and nesting within the support base. Mating projections and grooves in the tank and support base prevent relative movement of the three elements of the tank assembly. Each of the three elements is rotationally molded of cross-linked, high density polyethylene. Also disclosed is a method of forming an open-ended, inwardly projecting tubular member, or an open-ended outwardly projecting conduit, with or without a flange at its distal end, in a molded container.
摘要翻译：一个三件式的油箱组件，包括油箱，支撑底座和支撑衬套。罐具有锥形底部，其顶部具有排出管道; 与槽的侧壁一体形成的纵向波纹的反间隙填充槽; 以及整体形成的盖，其包括用于提供进入填充槽的通孔。排放管道可以包括流量阀和止回阀。基座包括用于与罐侧壁嵌套接合的侧壁，平坦的地面接合表面和用于接收叉车叉的横向纵向槽。支撑衬里具有直立的壁和用于支撑罐的锥形底部并嵌套在支撑基座内的锥形顶壁。罐和支撑基座中的配合突起和凹槽防止罐组件的三个元件的相对运动。三个元件中的每一个由交联的高密度聚乙烯旋转成型。还公开了一种在模制容器中形成开口的向内突出的管状构件或开口向外突出的导管，在其远端具有或不具有凸缘。
