    • An opener for tab-top, screw-top and crimped top beverage containers is disclosed. The opener comprises: an injection-molded, substantially flat, elongated handle of an essentially constant wall thickness having a central portion and two ends; a cavity molded in one end of the handle; a serrate frustoconical receptacle molded in the central portion of the handle; an opening molded in the other end of the handle; a passage also molded in the other end and communicating with the opening; and a steel insert frictionally retained in the passage, a portion of the insert protruding into the opening. In use, the cavity receives a tab-top tab, the receptacle engages a screw-top cap, or the opening receives a crimped-top cap, the insert engaging the edge of the cap. The ergonomic handle is then used as a lever to open the container. A permanent magnet may be attached to the opener to allow easy storage on a magnetic surface. The opener may be provided with holes for attaching a cord or tether.
    • 公开了顶盖,螺旋顶和卷边顶部饮料容器的开启器。 开启器包括:具有中心部分和两端的基本上恒定的壁厚的注射成型的,基本平坦的细长手柄; 模制在手柄的一端的模腔; 在手柄的中心部分模制的锯齿形截头圆锥形容器; 在手柄的另一端成型的开口; 在另一端模制并与开口连通的通道; 以及摩擦地保持在所述通道中的钢插入件,所述插入件的一部分突出到所述开口中。 在使用中,空腔容纳翼片形突片,插座接合螺旋盖,或者开口接收压接顶盖,插入物接合盖的边缘。 然后将符合人体工程学的手柄用作打开容器的杠杆。 永磁体可以连接到开启器以便容易地存储在磁性表面上。 开启器可以设置有用于附接绳索或系绳的孔。
