    摘要： A lightened, molded plastic closure exhibiting enhanced strength includes a top wall portion, and an internally threaded, depending annular skirt portion. The interior surface of the skirt portion, below the closure thread, defines an array of alternating grooves and lands, which together define a plurality of circumferentially spaced, vertically extending strengthening ribs on the inside surface of the skirt portion. The skirt portion thus exhibits desirably enhanced column strength, thereby facilitating efficient formation by “stripping” from an associated core pin during molding. In the preferred form, the exterior surface of the skirt portion is provided with a plurality of circumferentially spaced gripping knurls respectively aligned with the grooves defined at the interior surface of the skirt portion.

    摘要翻译： 具有增强强度的减轻的模制塑料封闭件包括顶壁部分和内螺纹的垂直环形裙部。 裙部的内表面在封闭线下方限定了交替的凹槽和平台的阵列，这些凹槽和平台在裙部的内表面上共同限定了多个周向间隔开的垂直延伸的加强肋。 因此，裙部显示出期望增强的柱强度，从而有助于通过在模制期间从相关的芯销“剥离”而进行有效的形成。 在优选形式中，裙部的外表面设置有分别与限定在裙部的内表面处的凹槽对准的多个周向间隔的夹紧滚花。
