    • A gasket (1) having a reversibly compressible lower portion (17), and an upper portion (14) having at least one upwardly extending extension, is described. The upper portion (14) of the gasket (1) includes a first (34) and optionally a second (37) upwardly extending extension, each having an exterior surface (43, 55). The first and second extensions of the upper portion each have a vertical center line (49, 58) that resides over (or extends through) an underlying exterior longitudinal groove (73, 76) of the lower portion, such that when the gasket is compressed along its vertical center axis (23) a force (79, 82) is exerted laterally outward along (or through) the exterior surfaces of the upwardly extending extensions. The force exerted laterally outward along the exterior surface of an upwardly extending extension serves to maintain a seal (214, 217) formed by abutment of the exterior surface of the extension with a separate surface (e.g., the upper edge (190, 193) of a channel (121) in which the gasket resides) while the gasket is reversibly compressed along its vertical center axis. Also described is a method of preparing a coated molded article (223) in a mold apparatus (8) that includes the gasket of the present invention.
    • 描述了具有可逆压缩的下部(17)的垫圈(1)和具有至少一个向上延伸的延伸部的上部(14)。 垫圈(1)的上部(14)包括第一(34)和任选的第二(37)向上延伸的延伸部,每个具有外表面(43,45)。 上部的第一和第二延伸部各自具有垂直的中心线(49,58),该垂直中心线位于下部的下面的外部纵向凹槽(或者延伸穿过)下方(或延伸穿过)下部的外部纵向凹槽(73,76),使得当垫圈被压缩 沿其垂直中心轴线(23)沿着(或穿过)向上延伸的延伸部分的外表面横向向外施加力(79,82)。 沿着向上延伸的延伸部的外表面横向向外施加的力用于保持通过将延伸部的外表面与分离的表面(例如,上部边缘(190,193))的邻接形成的密封件(214,217) 垫圈位于其中的通道(121),同时垫圈沿其垂直中心轴线可逆地压缩。 还描述了在包括本发明的垫圈的模具装置(8)中制备涂覆的模制品(223)的方法。
